Abstract
Background Studies have demonstrated low hepatitis A virus (HAV) vaccination rates among persons with HIV (PWH). Methods We conducted a retrospective study of persons entering HIV care at two clinics in Houston, Texas between 2010 and 2018. We defined those eligible for HAV vaccination as those who had no history of HAV vaccination and had a negative anti-HAV IgG at entry to care. Kaplan-Meier curves summarized time to receipt of HAV vaccines. The proportions of patients who received 1 and 2 HAV vaccines at 6, 12, and 24 months were estimated. Cox proportional hazards regression evaluated associations between patient characteristics and vaccination. Significant factors were included in a multivariable Cox proportional hazards model. Results Of 6,515 patients, 1372 were eligible for HAV vaccination. Of eligible patients, 29.2 % received 1 HAV vaccination at 6 months, 37.1 % at 12 months, and 47.8 % at 24 months. At 6 months, 10 % received 2 HAV vaccinations, 21.1 % at 12 months, and 33.4 % at 24 months. In multivariable analysis, men who have sex with men (adjusted HR 1.35, 95 % CI 1.06, 1.73) or those who had CD4 count ≥ 200 cells/µl (adjusted HR 2.52, 95 % CI 1.89, 3.37) had their second vaccination sooner than those who were not men who have sex with men or who had CD4 counts < 200 cells/µl, respectively. Patients > 50 years of age had their second vaccination sooner than those aged 30-50 years (adjusted HR 1.47, 95 % CI 1.08, 1.99). Those with active substance history had a longer time to second vaccination compared to those with no substance use history (adjusted HR 0.57, 95 % CI 0.40, 0.82). Conclusions HAV vaccination rates were low and highlight the need for effective solutions to address HAV immunization gaps in PWH, especially among young patients, those with active substance use disorders, and those with significant immunocompromise.

Interventions for improving coverage of childhood immunisation in low- and middle-income countries. Cochrane Database Syst Rev 2023; 12:CD008145.

Abstract
BACKGROUND Immunisation plays a major role in reducing childhood morbidity and mortality. Getting children immunised against potentially fatal and debilitating vaccine-preventable diseases remains a challenge despite the availability of efficacious vaccines, particularly in low- and middle-income countries. With the introduction of new vaccines, this becomes increasingly difficult. There is therefore a current need to synthesise the available evidence on the strategies used to bridge this gap. This is a second update of the Cochrane Review first published in 2011 and updated in 2016, and it focuses on interventions for improving childhood immunisation coverage in low- and middle-income countries. OBJECTIVES To evaluate the effectiveness of intervention strategies to boost demand and supply of childhood vaccines, and sustain high childhood immunisation coverage in low- and middle-income countries. SEARCH METHODS We searched CENTRAL, MEDLINE, CINAHL, and Global Index Medicus (11 July 2022). We searched Embase, LILACS, and Sociological Abstracts (2 September 2014). We searched WHO ICTRP and ClinicalTrials.gov (11 July 2022). In addition, we screened reference lists of relevant systematic reviews for potentially eligible studies, and carried out a citation search for 14 of the included studies (19 February 2020). SELECTION CRITERIA Eligible studies were randomised controlled trials (RCTs), non-randomised RCTs (nRCTs), controlled before-after studies, and interrupted time series conducted in low- and middle-income countries involving children that were under five years of age, caregivers, and healthcare providers. DATA COLLECTION AND ANALYSIS We independently screened the search output, reviewed full texts of potentially eligible articles, assessed the risk of bias, and extracted data in duplicate, resolving discrepancies by consensus. We conducted random-effects meta-analyses and used GRADE to assess the certainty of the evidence. MAIN RESULTS Forty-one studies involving 100,747 participants are included in the review. Twenty studies were cluster-randomised and 15 studies were individually randomised controlled trials. Six studies were quasi-randomised. The studies were conducted in four upper-middle-income countries (China, Georgia, Mexico, Guatemala), 11 lower-middle-income countries (Côte d'Ivoire, Ghana, Honduras, India, Indonesia, Kenya, Nigeria, Nepal, Nicaragua, Pakistan, Zimbabwe), and three lower-income countries (Afghanistan, Mali, Rwanda). The interventions evaluated in the studies were health education (seven studies), patient reminders (13 studies), digital register (two studies), household incentives (three studies), regular immunisation outreach sessions (two studies), home visits (one study), supportive supervision (two studies), integration of immunisation services with intermittent preventive treatment of malaria (one study), payment for performance (two studies), engagement of community leaders (one study), training on interpersonal communication skills (one study), and logistic support to health facilities (one study). We judged nine of the included studies to have low risk of bias; the risk of bias in eight studies was unclear and 24 studies had high risk of bias. We found low-certainty evidence that health education (risk ratio (RR) 1.36, 95% confidence interval (CI) 1.15 to 1.62; 6 studies, 4375 participants) and home-based records (RR 1.36, 95% CI 1.06 to 1.75; 3 studies, 4019 participants) may improve coverage with DTP3/Penta 3 vaccine. Phone calls/short messages may have little or no effect on DTP3/Penta 3 vaccine uptake (RR 1.12, 95% CI 1.00 to 1.25; 6 studies, 3869 participants; low-certainty evidence); wearable reminders probably have little or no effect on DTP3/Penta 3 uptake (RR 1.02, 95% CI 0.97 to 1.07; 2 studies, 1567 participants; moderate-certainty evidence). Use of community leaders in combination with provider intervention probably increases the uptake of DTP3/Penta 3 vaccine (RR 1.37, 95% CI 1.11 to 1.69; 1 study, 2020 participants; moderate-certainty evidence). We are uncertain about the effect of immunisation outreach on DTP3/Penta 3 vaccine uptake in children under two years of age (RR 1.32, 95% CI 1.11 to 1.56; 1 study, 541 participants; very low-certainty evidence). We are also uncertain about the following interventions improving full vaccination of children under two years of age: training of health providers on interpersonal communication skills (RR 5.65, 95% CI 3.62 to 8.83; 1 study, 420 participants; very low-certainty evidence), and home visits (RR 1.29, 95% CI 1.15 to 1.45; 1 study, 419 participants; very low-certainty evidence). The same applies to the effect of training of health providers on interpersonal communication skills on the uptake of DTP3/Penta 3 by one year of age (very low-certainty evidence). The integration of immunisation with other services may, however, improve full vaccination (RR 1.29, 95% CI 1.16 to 1.44; 1 study, 1700 participants; low-certainty evidence). AUTHORS' CONCLUSIONS Health education, home-based records, a combination of involvement of community leaders with health provider intervention, and integration of immunisation services may improve vaccine uptake. The certainty of the evidence for the included interventions ranged from moderate to very low. Low certainty of the evidence implies that the true effect of the interventions might be markedly different from the estimated effect. Further, more rigorous RCTs are, therefore, required to generate high-certainty evidence to inform policy and practice.

Abstract
Many social, cultural, and systemic challenges affect the uptake of measles immunisation services. Prior studies have looked at the caregivers' perspectives, but little is known about the perspectives of the health care providers on the barriers of measles immunisation services in Canada. This study examined measles immunisation coverage trends across the regional health authorities in Saskatchewan and explored the barriers and enablers to measles immunisation coverage from providers' perspectives. The study adopted an explanatory sequential mixed method. We utilized the entire population of 16,582 children under two years of age available in the Saskatchewan Immunisation Management System (SIMS) registry for 2002 and 2013 in aggregate format and interviewed 18 key informants in pre-determined two-stages in 2016 and 2017. The quantitative analysis was done with Joinpoint regression modelling, while the qualitative interview data was analyzed using hybrid inductive and deductive thematic approaches. There was a 16.89%-point increase in measles immunisation coverage in the province from 56.32% to 73.21% between 2002 and 2013. There was also a persistently higher coverage among the affluent (66.95% - 82.37%) than the most deprived individuals (45.79% - 62.60%) in the study period. The annual rate of coverage change was marginally higher among the most deprived (16.81%; and average annual percentage change (AAPC) 2.0, 95% CI 1.7-2.2) than among the affluent group (15.42% and AAPC 3.0; 95% CI 2.0-4.0). While access-related issues, caregivers' fears, hesitancy, anti-vaccination challenges, and resource limitations were barriers to immunisation, improving community engagement, service delivery flexibility, targeted social responses and increasing media role were found useful to address the uptake of measles and other vaccine-preventable diseases immunisation. There is low coverage and inequity in measles immunisation uptake in Saskatchewan from social and institutional barriers. Even though there is evidence of disparity reduction among the different groups, the barriers to increasing measles immunisation coverage have implications for the health of the socio-economically deprived groups, the healthcare system and other vaccination programs. There is a need to improve policy framework for community engagement, targeted programs, and public health discourse.

Vaccine 2022; 40:3356-3365. [PMID: 35487810 DOI: 10.1016/j.vaccine.2022.04.057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 03/10/2022] [Accepted: 04/15/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Despite important progress in global vaccination coverage, many countries are still facing preventable disease outbreaks. Timely vaccination is important in getting adequate protection against disease. In light of the paucity of relevant literature, this study investigated the timely completion of childhood routine immunization and identified factors associated with timely vaccination in Burkina Faso. METHODS We extracted data on child vaccination and other child characteristics from a household survey conducted across 24 districts in 2017. We extracted data on health system characteristics from a parallel facility survey. We applied a Kaplan-Meier time-to-event analysis to estimate timely vaccination coverage defined as the proportion of children that received a given vaccine in the period between three days before and 28 days after the recommended age. We used a Cox proportional hazard model with mixed effects to identify factors associated with timely vaccination. RESULTS In total, 3,138 children aged between 16 and 36 months who could present an immunization booklet were included in the study.The main finding is the existence of an important gap showing that timely vaccination coverage was lower than vaccination coverage. More specifically,this gap ranged from 16% for BCG to 43% for Penta 3. In addition, region and distance between the household and the nearest health facility were the main factors associated with timely full vaccination coverage and specifically for Penta3, MCV1 and MCV2. CONCLUSIONS This study highlights that timely vaccination coverage remains substantially lower than vaccination coverage. Timeliness of vaccination should therefore be considered as a metric to assess the status of immunization in a country. Geographical accessibility continues to represent a major barrier to timely vaccination, calling for specific interventions on both supply-side (e.g. outreach activities) and demand-side (e.g. vouchers or community-based interventions for vaccination) to counteract its negative effect.

Parents' and guardians' views and experiences of accessing routine childhood vaccinations during the coronavirus (COVID-19) pandemic: A mixed methods study in England. PLoS One 2020; 15:e0244049.

Abstract
Objective To explore parents’ and guardians’ views and experiences of accessing National Health Service (NHS) general practices for routine childhood vaccinations during the coronavirus (COVID-19) pandemic in England. Design Mixed methods approach involving an online cross-sectional survey (conducted between 19th April and 11th May 2020) and semi-structured telephone interviews (conducted between 27th April and 27th May 2020). Participants 1252 parents and guardians (aged 16+ years) who reported living in England with a child aged 18 months or under completed the survey. Nineteen survey respondents took part in follow-up interviews. Results The majority of survey respondents (85.7%) considered it important for their children to receive routine vaccinations on schedule during the COVID-19 pandemic; however, several barriers to vaccination were identified. These included a lack of clarity around whether vaccination services were operating as usual, particularly amongst respondents from lower income households and those self-reporting as Black, Asian, Chinese, Mixed or Other ethnicity; difficulties in organising vaccination appointments; and fears around contracting COVID-19 while attending general practice. Concerns about catching COVID-19 while accessing general practice were weighed against concerns about children acquiring a vaccine-preventable disease if they did not receive scheduled routine childhood vaccinations. Many parents and guardians felt their child’s risk of acquiring a vaccine-preventable disease was low as the implementation of stringent physical distancing measures (from March 23rd 2020) meant they were not mixing with others. Conclusion To promote routine childhood vaccination uptake during the current COVID-19 outbreak, further waves of COVID-19 infection, and future pandemics, prompt and sustained national and general practice level communication is needed to raise awareness of vaccination service continuation and the importance of timely vaccination, and invitation-reminder systems for vaccination need to be maintained. To allay concerns about the safety of accessing general practice, practices should communicate the measures being implemented to prevent COVID-19 transmission.

Abstract
Background There are high expectations that mobile health (mHealth) strategies will increase uptake of health care services, especially in resource strained settings. Our study aimed to evaluate effects of an mHealth intervention on uptake of maternal health services. Methods This was an intervention cohort study conducted at six public antenatal and postnatal care clinics in inner-city Johannesburg, South Africa. The intervention consisted of twice-weekly informative and pregnancy stage-based maternal health information text messages sent to women during pregnancy until their child was one year of age. The intervention arm of 87 mother-infant pairs was compared to a control arm of 90 pairs. Univariate and multivariate analyses were used to compare the probability of the outcome between the two groups. Results Intervention participants had higher odds of attending all government-recommended antenatal and postnatal visits, all recommended first year vaccinations (OR: 3.2, 95% CI 1.63–6.31) and had higher odds of attending at least the recommended four antenatal visits (OR: 3.21, 95% CI 1.73–5.98). Conclusion We show an improvement in achieving complete maternal-infant continuum of care, providing evidence of a positive impact of informative maternal mHealth messages sent to pregnant women and new mothers.

Electronic Health Record Portal Messages and Interactive Voice Response Calls to Improve Rates of Early Season Influenza Vaccination: Randomized Controlled Trial. J Med Internet Res 2020; 22:e16373. [PMID: 32975529 PMCID: PMC7547389 DOI: 10.2196/16373] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Revised: 06/24/2020] [Accepted: 08/03/2020] [Indexed: 01/30/2023] Open
Abstract
Background Patient reminders for influenza vaccination, delivered via an electronic health record patient portal and interactive voice response calls, offer an innovative approach to engaging patients and improving patient care. Objective The goal of this study was to test the effectiveness of portal and interactive voice response outreach in improving rates of influenza vaccination by targeting patients in early September, shortly after vaccinations became available. Methods Using electronic health record portal messages and interactive voice response calls promoting influenza vaccination, outreach was conducted in September 2015. Participants included adult patients within a large multispecialty group practice in central Massachusetts. Our main outcome was electronic health record–documented early influenza vaccination during the 2015-2016 influenza season, measured in November 2015. We randomly assigned all active portal users to 1 of 2 groups: (1) receiving a portal message promoting influenza vaccinations, listing upcoming clinics, and offering online scheduling of vaccination appointments (n=19,506) or (2) receiving usual care (n=19,505). We randomly assigned all portal nonusers to 1 of 2 groups: (1) receiving interactive voice response call (n=15,000) or (2) receiving usual care (n=43,596). The intervention also solicited patient self-reports on influenza vaccinations completed outside the clinic. Self-reported influenza vaccination data were uploaded into the electronic health records to increase the accuracy of existing provider-directed electronic health record clinical decision support (vaccination alerts) but were excluded from main analyses. Results Among portal users, 28.4% (5549/19,506) of those randomized to receive messages and 27.1% (5294/19,505) of the usual care group had influenza vaccinations documented by November 2015 (P=.004). In multivariate analysis of portal users, message recipients were slightly more likely to have documented vaccinations when compared to the usual care group (OR 1.07, 95% CI 1.02-1.12). Among portal nonusers, 8.4% (1262/15,000) of those randomized to receive calls and 8.2% (3586/43,596) of usual care had documented vaccinations (P=.47), and multivariate analysis showed nonsignificant differences. Over half of portal messages sent were opened (10,112/19,479; 51.9%), and over half of interactive voice response calls placed (7599/14,984; 50.7%) reached their intended target, thus we attained similar levels of exposure to the messaging for both interventions. Among portal message recipients, 25.4% of message openers (2570/10,112) responded to a subsequent question on receipt of influenza vaccination; among interactive voice response recipients, 72.5% of those reached (5513/7599) responded to a similar question. Conclusions Portal message outreach to a general primary care population achieved a small but statistically significant improvement in rates of influenza vaccination (OR 1.07, 95% CI 1.02-1.12). Interactive voice response calls did not significantly improve vaccination rates among portal nonusers (OR 1.03, 95% CI 0.96-1.10). Rates of patient engagement with both modalities were favorable.

Abstract
Background
Bias in the publication and reporting of research findings (referred to as publication and related bias here) poses a major threat in evidence synthesis and evidence-based decision-making. Although this bias has been well documented in clinical research, little is known about its occurrence and magnitude in health services and delivery research.
Objectives
To obtain empirical evidence on publication and related bias in quantitative health services and delivery research; to examine current practice in detecting/mitigating this bias in health services and delivery research systematic reviews; and to explore stakeholders’ perception and experiences concerning such bias.
Methods
The project included five distinct but interrelated work packages. Work package 1 was a systematic review of empirical and methodological studies. Work package 2 involved a survey (meta-epidemiological study) of randomly selected systematic reviews of health services and delivery research topics (n = 200) to evaluate current practice in the assessment of publication and outcome reporting bias during evidence synthesis. Work package 3 included four case studies to explore the applicability of statistical methods for detecting such bias in health services and delivery research. In work package 4 we followed up four cohorts of health services and delivery research studies (total n = 300) to ascertain their publication status, and examined whether publication status was associated with statistical significance or perceived ‘positivity’ of study findings. Work package 5 involved key informant interviews with diverse health services and delivery research stakeholders (n = 24), and a focus group discussion with patient and service user representatives (n = 8).
Results
We identified only four studies that set out to investigate publication and related bias in health services and delivery research in work package 1. Three of these studies focused on health informatics research and one concerned health economics. All four studies reported evidence of the existence of this bias, but had methodological weaknesses. We also identified three health services and delivery research systematic reviews in which findings were compared between published and grey/unpublished literature. These reviews found that the quality and volume of evidence and effect estimates sometimes differed significantly between published and unpublished literature. Work package 2 showed low prevalence of considering/assessing publication (43%) and outcome reporting (17%) bias in health services and delivery research systematic reviews. The prevalence was lower among reviews of associations than among reviews of interventions. The case studies in work package 3 highlighted limitations in current methods for detecting these biases due to heterogeneity and potential confounders. Follow-up of health services and delivery research cohorts in work package 4 showed positive association between publication status and having statistically significant or positive findings. Diverse views concerning publication and related bias and insights into how features of health services and delivery research might influence its occurrence were uncovered through the interviews with health services and delivery research stakeholders and focus group discussion conducted in work package 5.
Conclusions
This study provided prima facie evidence on publication and related bias in quantitative health services and delivery research. This bias does appear to exist, but its prevalence and impact may vary depending on study characteristics, such as study design, and motivation for conducting the evaluation. Emphasis on methodological novelty and focus beyond summative assessments may mitigate/lessen the risk of such bias in health services and delivery research. Methodological and epistemological diversity in health services and delivery research and changing landscape in research publication need to be considered when interpreting the evidence. Collection of further empirical evidence and exploration of optimal health services and delivery research practice are required.

Abstract
IMPORTANCE Timely identification of patients likely to miss seasonal influenza vaccination (SIV) could help health care practitioners tailor services and gain efficiency. OBJECTIVE To develop and validate a predictive model of SIV uptake among at-risk adults. DESIGN, SETTING, AND PARTICIPANTS This prognostic study constructed a prediction model for vaccine uptake by adults at increased risk of influenza-associated complications. Drawing from the Clinical Practice Research Datalink database's records of primary care data of 324 284 adults routinely collected at general practices across England from January 2011 to December 2016, logistic regression models were trained on data from patients registered from January 2012 to December 2013 and validated with out-of-sample data from patients registered from January 2015 to December 2016. Data were extracted from the database December 2018 and analyzed between September 2019 and December 2019. EXPOSURES Covariates included sex, age, race/ethnicity, smoking status, socioeconomic status, previous pneumococcal vaccination, prior season SIV uptake, and clinical risk conditions. MAIN OUTCOMES AND MEASURES The main outcome was patient-level SIV uptake. Model performance was measured via misclassification rate, Brier score, sensitivity, specificity, and area under the curve. RESULTS The training data sets consisted of 324 284 (aged 18 to 64 years) and 186 426 (aged 65 years or older) patients. The mean (SD) age in the training data among patients aged 18 to 64 years was 45 (13) years; 161 487 (49.8%) were women, and 102 133 (31.5%) were categorized as white. Among patients aged 65 years or older, the mean (SD) age was 77 (8) years; 96 169 (51.6%) were women, and 64 996 (34.9%) were categorized as white. The validation data sets consisted of 35 210 patients aged 18 to 64 years and 25 497 aged 65 years or older. The mean (SD) age in the validation data set among patients aged 18 to 64 years was 42 (14) years; 17 296 (49.1%) were women, and 13 346 (37.9%) were categorized as white. Among patients aged 65 years or older, the mean (SD) age was 73 (8) years; 13 135 (51.5%) were women, and 9641 (37.8) were categorized as white. Among patients aged 18 to 64 years, SIV uptake was 35.9% (95% CI, 35.7%-36.0%) and 32.6% (95% CI, 32.1%-33.1%) for the training and validation data sets, respectively. Among patients aged 65 years or older, SIV uptake was 83.1% (95% CI, 82.9%-83.2%) and 76.1% (95% CI, 75.5%-76.6%) for the training and validation data sets, respectively. Prior season SIV uptake and pneumococcal vaccination status were the best predictors of SIV uptake. Predicted SIV uptake probabilities for patients aged 18 to 64 years were reliable, but biased toward underpredicting, whereas, among patients aged 65 years or older, they were variable and biased toward overpredicting. Briefly, in out-of-sample validation among patients aged 18 to 64 years, misclassification rates were 0.163 to 0.164, Brier scores were 0.124 to 0.125, area under the receiver operating characteristic curve values ranged from 0.876 to 0.877, sensitivity ranged from 0.705 to 0.720, and specificity ranged from 0.896 to 0.902. In patients aged 65 years or older, misclassification rates were 0.120 to 0.125, Brier scores were 0.0953 to 0.0959, area under the receiver operating characteristic curve was 0.877, sensitivity ranged from 0.919 to 0.936, and specificity ranged from 0.680 to 0.753. CONCLUSIONS AND RELEVANCE This study suggests that data obtained from primary care records could accurately predict SIV uptake among at-risk adults. Further research is needed to assess the feasibility and efficacy of implementing this model in clinical settings.

Effect of State Immunization Information System Centralized Reminder and Recall on HPV Vaccination Rates. Pediatrics 2020; 145:peds.2019-2689. [PMID: 32253263 PMCID: PMC7193977 DOI: 10.1542/peds.2019-2689] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 01/15/2020] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Although autodialer centralized reminder and recall (C-R/R) from state immunization information systems (IISs) has been shown to raise childhood vaccination rates, its impact on human papillomavirus (HPV) vaccination rates is unclear. METHODS In a 4-arm pragmatic randomized controlled trial across 2 states, we randomly selected practices representative of the specialty (pediatrics, family medicine, and health center) where children received care. Within each practice, patients 11 to 17.9 years old who had not completed their HPV vaccine series (NY: N = 30 616 in 123 practices; CO: N = 31 502 in 80 practices) were randomly assigned to receive 0, 1, 2, or 3 IIS C-R/R autodialer messages per vaccine dose. We assessed HPV vaccine receipt via the IIS, calculated intervention costs, and compared HPV vaccine series initiation and completion rates across study arms. RESULTS In New York, HPV vaccine initiation rates ranged from 37.0% to 37.4%, and completion rates were between 29.1% and 30.1%, with no significant differences across study arms. In Colorado, HPV vaccine initiation rates ranged from 31.2% to 33.5% and were slightly higher for 1 reminder compared with none, but vaccine completion rates, ranging from 27.0% to 27.8%, were similar. On adjusted analyses in Colorado, vaccine initiation rates were slightly higher for 1 and 3 C-R/R messages (adjusted risk ratios 1.07 and 1.04, respectively); completion rates were slightly higher for 1 and 3 C-R/R messages (adjusted risk ratios 1.02 and 1.03, respectively). CONCLUSIONS IIS-based C-R/R for HPV vaccination did not improve HPV vaccination rates in New York and increased vaccination rates slightly in Colorado.

Abstract
Objective: To conduct educational and promotional outreach activities to general neurologists and
to increase self-enrollment of persons with amyotrophic lateral sclerosis (ALS) in the
National ALS Registry (Registry). Methods: A multicomponent project to educate neurologists and increase Registry self-enrollment
was delivered. Project components consisted of phone calls, mailings, train-the-trainer
presentations, and key informant interviews. Project-specific metrics, continuing
education enrollment, and Registry self-enrollment data were analyzed to measure project
efficacy. Results: Mailings were sent to 1561 neurologists in 6 states during 2015 to 2016. Sixty-five
percent of responding neurologists remembered the mailing 3 months after receipt. Of
providers who saw patients with ALS in the 3-month period, 60% read the provider guide,
22% distributed a patient guide, and 15% advised a patient to self-enroll. No changes in
self-enrollment rates were observed. Conclusion: Targeted mailings to providers can be used to educate them about the Registry; however,
most providers did not distribute materials to patients with ALS. Increases in providers
receiving Registry material did not lead to increases in patient self-enrollment. Practice Implications: General neurologists have competing priorities, and they see patients with ALS
infrequently. Neurologists could be the appropriate channel to distribute Registry
information to patients, but they are not the appropriate resource to assist patients
with self-enrollment. Engaging the support staff of busy specialists can help increase
research response rates and information distribution. The lessons learned from this
project can be applied to other rare conditions and disease specialists.

Abstract
Background and objective Guidelines for chronic obstructive pulmonary disease (COPD) advocate regular influenza vaccination, which has been shown to reduce exacerbations. However, influenza vaccination rates remain low. This quality improvement project was initiated to help improve influenza vaccination rates in a tertiary hospital. Methods All patients with COPD in the airway program (TAP) in the National University Hospital at the end of 2013 were recruited. The interventions were implemented in 2014; thus, population was stratified into the pre-intervention group and post-intervention group. Those who died in 2014 were excluded. They were (1) patient education posters in the clinics on the need for regular influenza vaccination, (2) direct interventions by physicians, and (3) intervention by the nurses when vaccinations were neglected. Physicians were made aware of previous vaccination rates, vaccination card reminders were placed in the clinics, and a new electronic healthcare record system (EHR) was implemented. The patients were followed up till the end of 2015 or until death. When an influenza vaccination was administered, the patients were asked which of the interventions led to the vaccination. A questionnaire was delivered to the physicians to determine the interventions that led to any change in vaccination prescription practices. Results The pre-intervention influenza vaccination rate was low at 47.7%. The post-intervention influenza vaccination rate improved to 80.7% with the multi-pronged approach. Physicians initiated the majority of vaccinations (87.9%), while nurses helped intervene in a further 12.1%. Physicians’ vaccination prescription practices changed as a result of self-awareness of low vaccination rates, vaccination card reminders, and the new EHR. Patient education made minimal impact. Conclusion This project demonstrates that with regular audits to track progress and several easy-to-implement interventions, improving influenza vaccination rates is an achievable goal.

Home-based records and vaccination appointment stickers as parental reminders to reduce vaccination dropout in Indonesia: A cluster-randomized controlled trial. Vaccine 2019; 37:6814-6823.

Abstract
INTRODUCTION Limited evidence is available about the effectiveness of strategies to remind caregivers when to bring children back for future vaccinations in low- and middle-income country settings. We evaluated the effectiveness of two reminder strategies based on home-based vaccination records (HBR) in Indonesia. METHODS In this cluster-randomized controlled trial involving 3616 children <1 year of age, 90 health facilities were randomly assigned to either a control group or one of two intervention groups: (1) HBR-only group, where healthcare workers provided an HBR to any child without an HBR during a vaccination visit and instructed the caregiver to keep it at home between visits, or (2) HBR + sticker group, where, in addition to HBR provision, healthcare workers placed vaccination appointment reminder stickers on the HBR. The primary outcome was receipt of the third dose of diphtheria-tetanus-pertussis-containing vaccine (DTPcv3) within 7 months and the secondary outcome was receipt of a timely DTPcv3 dose. RESULTS Control group DTPcv3 coverage was 81%. In intention-to-treat analysis, neither intervention group had significantly different DTPcv3 coverage compared with the control group (RR = 0.94, 95% confidence interval [CI] 0.87; 1.02 for HBR-only group; RR = 0.97, 95% CI 0.90; 1.04 for HBR + sticker group) by study end. However, children in the HBR + sticker group were 50% more likely to have received a DTPcv3 vaccination (RR = 1.46, 95% CI 1.02, 2.09) within 60 days of DTPcv1 vaccination, compared with children in the control group; children in the HBR-only group were not more likely to have done so (RR = 1.05, 95% CI 0.71, 1.55). DISCUSSION Reminder stickers had an immediate effect on coverage by improving the proportion of children who received a timely DTPcv3 dose but no effect on the proportion who received DTPcv3 after 7 months. Coupling reminder stickers with strategies to address other reasons why children do not return for vaccination visits should be further explored.

Abstract
Background and aimsSeasonal influenza vaccination (SIV) uptake (SIVU) rates in France are below target. We (i) describe trends in French SIVU over 10 consecutive seasons among different target groups and (ii) examine the effects of the 2009 influenza A(H1N1) pandemic and the publication of new SIV recommendations in 2011 and 2013.MethodsOur study was based on records of vaccines delivered in community pharmacies for a permanent, representative sample of 805,000 beneficiaries of the French National Health Insurance Fund. For the first objective, we analysed SIVU rate trends among ≥ 65 year olds as well as among < 65 year olds with each of the following conditions: diabetes, respiratory, cardiovascular, neuromuscular, or chronic liver disease. For the second goal, we computed segmented log-binomial regression analyses.ResultsAfter the 2009 pandemic, except for the target group with liver diseases, where the difference was not statistically significant, SIVU fell significantly in all groups during the 2010/11 season, remaining relatively stable until 2015/16 in groups not targeted by new recommendations. Crude SIVU rates in 2015/16 were 48% (43,950/91,794) for ≥ 65 year olds and between 16% (407/2,565) and 29% (873/3,056) for < 65 year olds depending on their condition. SIVU increased modestly after new recommendations were published, but only in patients newly eligible for a free vaccine voucher.ConclusionsOur results suggest: (i) a prolonged confidence crisis in SIV, initially impelled by the 2009 pandemic vaccination campaign; (ii) that new recommendations are ineffective without additional measures. Interventional research in this field is a priority.

In 2018, the Victorian government implemented a free hepatitis A vaccination programme targeting all Victorian MSM. This study aimed to determine hepatitis A vaccine uptake among MSM in a sexual health clinic in Melbourne. METHODS All MSM attending the Melbourne Sexual Health Centre (MSHC) in 2018 were included. Chart review was performed to determine the proportion of men vaccinated for at least one dose of hepatitis A and to examine why men did not receive the vaccine. Multivariable logistic regression was performed to examine the factors associated with vaccine uptake. Vaccine uptake was defined as receipt of at least one dose of hepatitis A vaccine. RESULTS Of the 9582 MSM who attended MSHC in 2018, 61.3% (95% CI 60.3% to 62.2%) self-reported already being immune to hepatitis A. Of the 3713 remaining eligible men, 62.7% (95% CI 61.1% to 64.2%) received at least one dose of the hepatitis A vaccine on the day of attendance. Compared with MSM not living with HIV and not taking pre-exposure prophylaxis (PrEP), MSM taking PrEP (adjusted OR 1.28; 95% CI 1.01 to 1.62) were more likely to receive the vaccine. 1386 men (37.3%) did not receive the vaccine and 55.4% were not offered the vaccine by their treating clinician. 300 men (21.6%) were identified as non-immune after serological testing but did not return for vaccination. By the end of 2018, 85.5% of MSHC attendees (8196/9582) were immune to hepatitis A. CONCLUSION The critical vaccination threshold for hepatitis A has been estimated at >70%. Continuation of the targeted hepatitis A vaccination programme will improve immunity among the MSM population to prevent ongoing transmission and the likelihood of future outbreaks.

Text Message Reminders and Unconditional Monetary Incentives to Improve Measles Vaccination in Western Kenya: Study Protocol for the Mobile and Scalable Innovations for Measles Immunization Randomized Controlled Trial. JMIR Res Protoc 2019; 8:e13221. [PMID: 31290405 PMCID: PMC6647752 DOI: 10.2196/13221] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2018] [Revised: 04/11/2019] [Accepted: 04/28/2019] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Globally, 21 million children do not receive the measles vaccine each year. With high levels of mobile phone access and ownership, opportunities exist to leverage mobile health technologies to generate demand for immunization. OBJECTIVE The aim of the Mobile and Scalable Innovations for Measles Immunization trial is to determine if text message (short message service, SMS) reminders, either with or without mobile phone-based incentives, can improve measles immunization coverage and timeliness in rural western Kenya. METHODS This is a 3-arm, parallel, randomized controlled trial (RCT). Using simple randomization, caregivers in Siaya County, Kenya, will be randomized and evenly allocated to 1 of 3 study arms: (1) control, (2) SMS reminders only, and (3) SMS reminders plus a 150 Kenyan Shilling (KES) incentive. Participants assigned to the SMS group will be sent SMS reminders 3 days before and on the day before the measles immunization visit scheduled for when the child is 9 months of age. Participants in the incentive arm will, in addition to SMS reminders as above, be sent an unconditional 150 KES mobile-money incentive to their mobile phone 3 days before the child becomes 9 months of age. Children will be followed up to the age of 12 months to assess the primary outcome, a measles vaccination by 10 months of age. Log-binomial regressions will be used to calculate relative risks. RESULTS Enrollment was completed in March 2017. We enrolled 537 caregivers and their infants into the following groups: control (n=179), SMS reminders only (n=179), and SMS reminders plus 150 KES (n=179). Results will be made publicly available in 2020. CONCLUSIONS Few RCTs have examined the effect of text message reminders to improve measles immunization coverage. This is the first study to assess the effect of SMS reminders with and without unconditionally provided mobile-money incentives to improve measles immunization coverage.

Abstract
Background After documenting insufficient vaccinations in 444 liver transplant (LT) patients, we investigated the effects of a combined strategy (addressing both patients and primary care physicians) on immunization prevalences after a 3‐year follow‐up. Methods The primary care physicians of all adult LT patients from a university center received a written recommendation addressing immunization needs. Patients were asked for their vaccination documents by phone. Changes in immunization rates for vaccine‐preventable diseases after the intervention were calculated based on patients’ immunization documents from 2014‐2016. Results The study cohort consisted of 401 patients. Prevalence rates for all vaccinations improved during the intervention period compared to the baseline study: tetanus from 88.3% to 92.8%, diphtheria from 80.0% to 89.0%, hepatitis A from 50.1% to 60.8%, hepatitis B from 66.3% to 77.1%, and pneumococci from 62.8% to 76.3%. The influenza vaccination rate improved, but remained at a low level before (2010:13%, 2011:11.5%, 2012:19%) and during the intervention (2014:27.4%, 2015:24.4%, 2016:23.2%). Despite these vaccinations, the prevalence rates of the quality indicators standard vaccinations completed (2013:17.2%; 2016:21.2%), indicated vaccinations completed (2013:2.7%, 2016:4.5%), and all vaccinations completed (2013:1%; 2016 1.5%) improved only slightly. Conclusions Our results demonstrated that intensified communication by written information to the primary care physician and phone calls to the patients improved the number of vaccinations. Nonetheless, a potential for further improvement persists, especially with regard to annual influenza vaccinations.

Randomized controlled trial of centralized vaccine reminder/recall to improve adult vaccination rates in an accountable care organization setting. Prev Med Rep 2019; 15:100893. [PMID: 31193580 PMCID: PMC6536777 DOI: 10.1016/j.pmedr.2019.100893] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2018] [Revised: 05/06/2019] [Accepted: 05/12/2019] [Indexed: 01/05/2023] Open
Abstract
Our objectives were to assess 1) effectiveness of using Colorado's Immunization Information System (CIIS) to send out vaccine reminder/recalls (R/Rs) centrally vs. usual care for adult vaccine delivery within an accountable care organization (ACO) and 2) practice staff's perception of centralized R/R. From 9/2016 to 4/2017, we conducted a randomized controlled trial among adults enrolled in a Medicaid ACO at six healthcare entities. Adults were divided into two strata: 15,153 age 19–64 and 616 age 65+. Adults age 19–64 who needed influenza and/or Tdap vaccine, and adults age 65+ who needed influenza, and/or Tdap, and/or a pneumococcal vaccine were randomized to receive up to 3 R/Rs by autodialed telephone and mail or usual care. Documentation of receipt of any needed vaccines in CIIS within six months was the primary outcome. We assessed intervention effectiveness using mixed effect logistic regression. Thirteen semi-structured exit interviews were conducted with staff from each healthcare entity. The intervention was not associated with the primary outcome for the age 19–64 population [OR 1.06 (95% CI 0.98–1.15)] or age 65+ population [(OR 0.96 (0.69–1.32)]. Practice staff perceived the intervention to be beneficial and not burdensome. Perceived barriers included lack of availability of appointments and adults receiving only influenza vaccine when other vaccines were needed. In conclusion, centralized R/R was not effective at improving adult vaccination rates in a Medicaid ACO. Future studies should consider better harmonizing vaccine centralized R/Rs with vaccine delivery efforts within the practice setting. Clinical Trials Registration Number: NCT02133391.

Abstract
Routine vaccination is among the most effective clinical interventions to prevent diseases as it is estimated to save over 3 million lives every year. However, the full potential of global immunization programs is not realised because population coverage is still suboptimal. This is also due to the inadequate immune response and paucity of informative correlates of protection upon immunization of vulnerable individuals such as newborns, preterm infants, pregnant women, and elderly individuals as well as those patients affected by chronic and immune compromising medical conditions. In addition, these groups are undervaccinated for a number of reasons, including lack of awareness of vaccine-preventable diseases and uncertainty or misconceptions about the safety and efficacy of vaccination by parents and healthcare providers. The presence of these nonresponders/undervaccinated individuals represents a major health and economic burden to society, which will become particularly difficult to address in settings with limited public resources. This review describes innovative and experimental approaches that can help identify specific genomic profiles defining nonresponder individuals for whom specific interventions might be needed. We will provide examples that show how such information can be useful to identify novel biomarkers of safety and immunogenicity for future vaccine trials. Finally, we will discuss how system biology “OMICs” data can be used to design bioinformatic tools to predict the vaccination outcome providing genetic and molecular “signatures” of protective immune response. This strategy may soon enable identification of signatures highly predictive of vaccine safety, immunogenicity, and efficacy/protection thereby informing personalized vaccine interventions in vulnerable populations.

Abstract
Human papillomavirus (HPV) vaccine series completion among adolescent Hispanic males (35%) is lower than the Healthy People 2020 80% goal. This directed qualitative content analysis identified mothers' beliefs about their sons completing the series. We found that mothers (N = 19) (1) express positive feelings; (2) believe the vaccine has positive effects; (3) identify the father and doctors as supporters and friends as nonsupporters; (4) list health insurance, transportation, and clinic reminders as facilitators; and (5) mention affordability as a barrier to vaccine completion. Results provide guidance for interventions. Increasing HPV vaccination among boys will decrease the overall incidence of HPV in this population.

Crocker-Buque T, Mounier-Jack S. Vaccination in England: a review of why business as usual is not enough to maintain coverage. BMC Public Health 2018; 18:1351. [PMID: 30522459 PMCID: PMC6282278 DOI: 10.1186/s12889-018-6228-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Accepted: 11/19/2018] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND The vaccine system in England underwent radical changes in 2013 following the implementation of the Health and Social Care Act. There have since been multi-year decreases in coverage of many vaccines. Healthcare professionals have reported finding the new system fragmented and challenging. This study aims to produce a logic model of the new system and evaluate the available evidence for interventions to improve coverage. METHODS We undertook qualitative document analysis to develop the logic model using process evaluation methods. We performed a systematic review by searching 12 databases with a broad search strategy to identify interventions studied in England conducted between 2006 and 2016 and evaluated their effectiveness. We then compared the evidence base to the logic model. RESULTS We analysed 83 documents and developed a logic model describing the core inputs, processes, activities, outputs, outcomes and impacts of the new vaccination system alongside the programmatic assumptions for each stage. Of 9,615 unique articles, we screened 624 abstracts, 45 full-text articles, and included 16 studies: 8 randomised controlled trials and 8 quasi-experimental studies. Four studies suggest that modifications to the contracting and incentive systems can increase coverage, but changes to other programme inputs (e.g. human or capital resources) were not evaluated. Four multi-component intervention studies modified activities and outputs from within a GP practice to increase coverage, but were part of campaigns or projects. Thus, many potentially modifiable factors relating to routine programme implementation remain unexplored. Reminder/recall systems are under-studied in England; incentive payments to adolescents may be effective; and only two studies evaluated carer information. CONCLUSIONS The evidence base for interventions to increase immunisation coverage in the new system in England are limited by a small number of studies and by significant risk of bias. Several areas important to primary care remain unexplored as targets for interventions, especially modification to organisational management.

Abstract
BACKGROUND Primary healthcare facility managers (PHFMs) occupy a unique position in the primary healthcare system, as the only cadre combining frontline clinical activities with managerial responsibilities. Often serving as 'street-level bureaucrats,' their perspectives can provide contextually relevant information about interventions for strengthening primary healthcare delivery, yet such perspectives are under-represented in the literature on primary healthcare strengthening. Our objective in this study was to explore perspectives of PHFMs in western Kenya regarding how to leverage human resource factors to improve immunization programs, in order to draw lessons for strengthening of primary healthcare delivery. METHODS We employed a sequential mixed methods approach. We conducted in-depth interviews with key informants in Kakamega County. Emergent themes guided questionnaire development for a cross-sectional survey. We randomly selected 94 facility managers for the survey which included questions about workload, effects of workload on immunization program, and appropriate measures to address workload effects. Participants provided self-assessment of their general motivation at work, their specific motivation to ensure that all children in their catchment areas were fully immunized, and recommendations to improve motivation. Participants were asked about frequency of supervisory visits, supervisor activities during those visits, and how to improve supervision. RESULTS The most frequently reported consequences of high workload were reduced accuracy of vaccination records (47%) and poor client counseling (47%). Hiring more clinical staff was identified as an effective remedy to high workload (69%). Few respondents (20%) felt highly motivated to ensure full immunization coverage and only 13% reported being very motivated to execute their role as a health worker generally. Increasing frequency of supervisory visits and acting on the feedback received during those visits were mostly perceived as important measures to improve program effectiveness. CONCLUSION Besides increasing the number of staff providing clinical care, PHFMs endorsed introducing some financial incentives contingent on specified targets and making supervisory visits meaningful with action on feedback as strategies to increase program effectiveness in primary healthcare facilities in Kenya. Targeting health worker motivation and promoting supportive supervision may reduce missed opportunities and poor client counseling in primary healthcare facilities in Kenya.

Abstract
BACKGROUND Improved communication about childhood vaccination is fundamental to increasing vaccine uptake in low-income countries. Mozambique, with 64% of children fully vaccinated, uses a range of communication interventions to promote uptake of childhood immunisation. OBJECTIVES Using a taxonomy developed by the 'Communicate to Vaccinate' (COMMVAC) project, the study aims to identify and classify the existing communication interventions for vaccination in Mozambique and to find the gaps. METHODS We used a qualitative research approach to identify the range of communication interventions used in Mozambique. In-depth semi-structured interviews were carried out with key purposively selected personnel at national level and relevant documents were collected and analysed. These data were complemented with observations of communication during routine vaccination and campaigns in Nampula province. We used the COMMVAC taxonomy, which organises vaccination communication intervention according to its intended purpose and the population targeted, to map both routine and campaign interventions. RESULTS We identified interventions used in campaign and routine vaccination, or in both, fitting five of the seven taxonomy purposes, with informing or educating community members predominating. We did not identify any interventions that aimed to provide support or facilitate decision-making. There were interventions for all main target groups, although fewer for health providers. Overlap occurred: for example, interventions often targeted both parents and community members. CONCLUSIONS We consider that the predominant focus on informing and educating community members is appropriate in the Mozambican context, where there is a high level of illiteracy and poor knowledge of the reasons for vaccination. We recommend increasing interventions for health providers, in particular training them in better communication for vaccination. The taxonomy was useful for identifying gaps, but needs to be more user-friendly if it is to be employed as a tool by health service managers.

Abstract
BACKGROUND Reminders for influenza vaccination improve influenza vaccination coverage. The purpose of this study was to describe the receipt of reminders for influenza vaccination during the 2011-12 influenza season among US adults. METHODS We analyzed data from the March 2012 National Flu Survey (NFS), a random digit dial telephone survey of adults in the United States. Relative to July 1, 2011, respondents were asked whether they received a reminder for influenza vaccination and the source and type of reminder they received. The association between reminder receipt and demographic variables, and the association between influenza vaccination coverage and receipt of reminders were also examined. RESULTS Of adults interviewed, 17.2% reported receiving a reminder since July 1, 2011. More than half (65.2%) of the reminders were sent by doctor offices. Hispanics and non-Hispanic blacks were more likely than non-Hispanic whites to report receiving a reminder. Adults who reported having a usual healthcare provider, health insurance, or a high-risk condition were more likely to report receiving reminders than the respective reference group. Adults reporting receipt of reminders were 1.15 times more likely (adjusted prevalence ratio, 95% CI: 1.06-1.25) to report being vaccinated for influenza than adults reporting not receiving reminders. CONCLUSIONS Differences exist in receipt of influenza vaccination reminders among adults. Reminders are important tools to improve adult influenza vaccination coverage. Greater use of reminders may lead to higher rates of adult influenza vaccination coverage and reductions in influenza-related morbidity.

Abstract
Introduction A majority of otolaryngologists have not had direct experience with many vaccine-preventable diseases since the creation of national vaccination programs. Despite the elimination of endemic transmission of some of these diseases in the United States, outbreaks can occur anywhere and still pose a threat to public health around the world. Recent outbreaks and changing trends in exemption rates indicate that it is important for physicians to maintain a working knowledge of how these diseases present and of the recommended treatment guidelines. Objectives This review will evaluate the current state of vaccination rates, vaccine exemption rates and disease incidence in the United States and in the world. It will also examine the clinical presentation and treatment recommendations of these diseases. Data Synthesis United States estimated vaccination rates, vaccine exemption rates and vaccine-preventable disease incidences were obtained from data compiled by the Centers for Disease Control and Prevention. World vaccination rates and disease incidences were obtained from the World Health Organization databases, which compile official figures reported by member states. A PubMed literature review provided information on the current state of vaccination exemptions and outbreaks in the United States. Conclusion Vaccination and vaccine exemption rates continue to put the United States and many areas of the world at risk for outbreaks of vaccine-preventable diseases.

Patient attitudes toward influenza and tetanus, diphtheria and acellular pertussis vaccination in pregnancy. Vaccine 2018; 36:4548-4554. [PMID: 29907484 DOI: 10.1016/j.vaccine.2018.05.121] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2017] [Revised: 04/26/2018] [Accepted: 05/31/2018] [Indexed: 11/23/2022]
Abstract
BACKGROUND Routine influenza and tetanus, diphtheria and acellular pertussis (Tdap) vaccination of pregnant women to prevent poor maternal, fetal and neonatal outcomes is recommended practice; however, actual rates of influenza vaccine acceptance are typically well below the (Healthy People 2020, 2015) goal of 80%. OBJECTIVE We sought to identify barriers to accepting either vaccination. MATERIALS AND METHODS From December 2014 to April 2015 women were given a questionnaire eliciting their experiences, attitudes and history of influenza and Tdap vaccination in pregnancy during their routine prenatal care appointments at a tertiary care center. Patient demographics were included in the questionnaire. A similar questionnaire was administered to prenatal care providers. Patient influenza and Tdap vaccination acceptance rates were compared and predictors of vaccine acceptance were analyzed with bivariate logistic regression. RESULTS Out of the 400 patient questionnaires distributed, 338 (84.5%) were completed and returned; 24 of 45 (53.3%) provider questionnaires were returned. Vaccination acceptance rates were 70.7% for the influenza vaccine and 76.3% for the Tdap vaccine. The logistic regression model indicated that predictors of acceptance for either vaccine in pregnancy are patient attitude and previous vaccination history. Patient attitudes were more favorable towards Tdap than influenza vaccination. The combination of healthcare provider recommendation and educational materials was significantly predictive of both Tdap and influenza vaccine acceptance. The most common reasons given for declining the influenza vaccine were safety concerns; the most common reasons given for declining the Tdap vaccine were that patients did not think it was required again when they received the vaccine before pregnancy. CONCLUSIONS Our study suggests that providers can improve Tdap and influenza vaccination acceptance in pregnancy by recommending the vaccination in combination with provision of educational materials on the vaccines.

Abstract
BACKGROUND The effectiveness of interventions to increase influenza vaccination uptake in people aged 60 years and older varies by country and participant characteristics. This review updates versions published in 2010 and 2014. OBJECTIVES To assess access, provider, system, and societal interventions to increase the uptake of influenza vaccination in people aged 60 years and older in the community. SEARCH METHODS We searched CENTRAL, which includes the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE, Embase, CINAHL, and ERIC for this update, as well as WHO ICTRP and ClinicalTrials.gov for ongoing studies to 7 December 2017. We also searched the reference lists of included studies. SELECTION CRITERIA Randomised controlled trials (RCTs) and cluster-randomised trials of interventions to increase influenza vaccination in people aged 60 years or older in the community. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as specified by Cochrane. MAIN RESULTS We included three new RCTs for this update (total 61 RCTs; 1,055,337 participants). Trials involved people aged 60 years and older living in the community in high-income countries. Heterogeneity limited some meta-analyses. We assessed studies as at low risk of bias for randomisation (38%), allocation concealment (11%), blinding (44%), and selective reporting (100%). Half (51%) had missing data. We assessed the evidence as low-quality. We identified three levels of intervention intensity: low (e.g. postcards), medium (e.g. personalised phone calls), and high (e.g. home visits, facilitators).Increasing community demand (12 strategies, 41 trials, 53 study arms, 767,460 participants)One successful intervention that could be meta-analysed was client reminders or recalls by letter plus leaflet or postcard compared to reminder (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.07 to 1.15; 3 studies; 64,200 participants). Successful interventions tested by single studies were patient outreach by retired teachers (OR 3.33, 95% CI 1.79 to 6.22); invitations by clinic receptionists (OR 2.72, 95% CI 1.55 to 4.76); nurses or pharmacists educating and nurses vaccinating patients (OR 152.95, 95% CI 9.39 to 2490.67); medical students counselling patients (OR 1.62, 95% CI 1.11 to 2.35); and multiple recall questionnaires (OR 1.13, 95% CI 1.03 to 1.24).Some interventions could not be meta-analysed due to significant heterogeneity: 17 studies tested simple reminders (11 with 95% CI entirely above unity); 16 tested personalised reminders (12 with 95% CI entirely above unity); two investigated customised compared to form letters (both 95% CI above unity); and four studies examined the impact of health risk appraisals (all had 95% CI above unity). One study of a lottery for free groceries was not effective.Enhancing vaccination access (6 strategies, 8 trials, 10 arms, 9353 participants)We meta-analysed results from two studies of home visits (OR 1.30, 95% CI 1.05 to 1.61) and two studies that tested free vaccine compared to patient payment for vaccine (OR 2.36, 95% CI 1.98 to 2.82). We were unable to conduct meta-analyses of two studies of home visits by nurses plus a physician care plan (both with 95% CI above unity) and two studies of free vaccine compared to no intervention (both with 95% CI above unity). One study of group visits (OR 27.2, 95% CI 1.60 to 463.3) was effective, and one study of home visits compared to safety interventions was not.Provider- or system-based interventions (11 strategies, 15 trials, 17 arms, 278,524 participants)One successful intervention that could be meta-analysed focused on payments to physicians (OR 2.22, 95% CI 1.77 to 2.77). Successful interventions tested by individual studies were: reminding physicians to vaccinate all patients (OR 2.47, 95% CI 1.53 to 3.99); posters in clinics presenting vaccination rates and encouraging competition between doctors (OR 2.03, 95% CI 1.86 to 2.22); and chart reviews and benchmarking to the rates achieved by the top 10% of physicians (OR 3.43, 95% CI 2.37 to 4.97).We were unable to meta-analyse four studies that looked at physician reminders (three studies with 95% CI above unity) and three studies of facilitator encouragement of vaccination (two studies with 95% CI above unity). Interventions that were not effective were: comparing letters on discharge from hospital to letters to general practitioners; posters plus postcards versus posters alone; educational reminders, academic detailing, and peer comparisons compared to mailed educational materials; educational outreach plus feedback to teams versus written feedback; and an intervention to increase staff vaccination rates.Interventions at the societal levelNo studies reported on societal-level interventions.Study funding sourcesStudies were funded by government health organisations (n = 33), foundations (n = 9), organisations that provided healthcare services in the studies (n = 3), and a pharmaceutical company offering free vaccines (n = 1). Fifteen studies did not report study funding sources. AUTHORS' CONCLUSIONS We identified interventions that demonstrated significant positive effects of low (postcards), medium (personalised phone calls), and high (home visits, facilitators) intensity that increase community demand for vaccination, enhance access, and improve provider/system response. The overall GRADE assessment of the evidence was moderate quality. Conclusions are unchanged from the 2014 review.

Improving Rates of Outpatient Influenza Vaccination Through EHR Portal Messages and Interactive Automated Calls: A Randomized Controlled Trial. J Gen Intern Med 2018; 33:659-667. [PMID: 29383550 PMCID: PMC5910339 DOI: 10.1007/s11606-017-4266-9] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2017] [Revised: 09/17/2017] [Accepted: 12/04/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND Patient reminders for influenza vaccination, delivered via electronic health record (EHR) patient portal messages and interactive voice response (IVR) calls, offer an innovative approach to improving patient care. OBJECTIVE To test the effectiveness of portal and IVR outreach in improving rates of influenza vaccination. DESIGN Randomized controlled trial of EHR portal messages and IVR calls promoting influenza vaccination. PARTICIPANTS Adults with no documented influenza vaccination 2 months after the start of influenza season (2014-2015). INTERVENTION Using a factorial design, we assigned 20,000 patients who were active portal users to one of four study arms: (a) receipt of a portal message promoting influenza vaccines, (b) receipt of IVR call with similar content, (c) both a and b, or (d) neither (usual care). We randomized 10,000 non-portal users to receipt of IVR call or usual care. In all intervention arms, information on pneumococcal vaccination was included if the targeted patient was overdue for pneumococcal vaccine. MAIN MEASURES EHR-documented influenza vaccination during the 2014-2015 influenza season, measured April 2015. KEY RESULTS Among portal users, 14.0% (702) of those receiving both portal messages and calls, 13.4% (669) of message recipients, 12.8% (642) of call recipients, and 11.6% (582) of those with usual care received vaccines. On multivariable analysis of portal users, those receiving portal messages alone (OR 1.20, 95% CI 1.06-1.35) or IVR calls alone (OR 1.15 95% CI 1.02-1.30) were more likely than usual care recipients to be vaccinated. Those receiving both messages and calls were also more likely than the usual care group to be vaccinated (ad hoc analysis, using a Bonferroni correction: OR 1.29, 97.5% CI 1.13, 1.48). Among non-portal users, 8.5% of call recipients and 8.6% of usual care recipients received influenza vaccines (p = NS). Pneumococcal vaccination rates showed no significant improvement. CONCLUSIONS Our outreach achieved a small but significant improvement in influenza vaccination rates. Registration: ClinicalTrials.gov Identifier NCT02266277 ( https://clinicaltrials.gov/ct2/show/NCT02266277 ).

Abstract
Introduction: In the era of highly effective vaccines for Hepatitis A Virus (HAV) and Hepatitis B Virus (HBV), acute viral hepatitis in patients with a chronic liver disease remains a public health concern. Vaccination for HAV and HBV is endorsed by all liver society guidelines. The aim of our study was to determine the rates of immunization in an internal medicine resident clinic. Methods: We identified patients with a chronic liver disease seen at the University of Oklahoma Internal Medicine resident clinic between June 2014 and May 2015. ICD-9 code 571 was used to identify patients with a chronic liver disease. Vaccination records and patient data were reviewed. Results: A total of 141 patients with a chronic liver disease (mean age 54.1 years, 56% males) were identified. Almost half of the patients (47.5%) were also being seen in the gastroenterology clinic. During the internal medicine resident clinic visit, vaccination against HAV and HBV was addressed for 50% and 46% of the patients, respectively. Patients being seen by senior residents were more likely to be immunized against HAV (OR 2.7, p=0.009) and HBV (OR 2.1, p=0.03). Patients followed in the GI clinic were more likely to be immunized against HAV (OR 2.1, p= 0.02) and HBV (OR 2.0, p=0.02). The gender of the treating physician and etiology had no impact on vaccination rates. Discussion: Immunization rates for HAV and HBV remain subpar despite clear guidelines for patients with a chronic liver disease. This provides an important avenue for improvement. Different strategies, including resident education, developing vaccination protocols, and referral to the gastroenterology clinic, are likely to improve vaccination status for patients with chronic liver diseases.

Abstract
Background Vaccine-preventable diseases among high-risk patients are a public health priority in high-income countries. Most national immunization programs have included vaccination recommendations for these population groups but they remain hard-to-reach and coverage data are poorly available. In a pilot study, we developed and tested an automated approach for identifying individuals with underlying medical conditions to feed an immunization information system (IIS). Methods We reviewed published recommendations on medical conditions that indicate vaccination against influenza, pneumococcal disease, meningococcal disease, hepatitis A, and hepatitis B. For each medical condition, we identified the International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis and procedure codes, the user fee exempt codes and the Anatomical Therapeutic Chemical Classification System codes and we reported these data in correspondence tables. Using these tables, we extracted three lists of patients recorded in three current data sources between 2001 and 2010 in the Apulia region of Italy: the hospital discharge registry, the user fee exempt registry, and the drug prescription registry. Using a unique personal identification number, we linked these three lists of patients with the regional IIS (2012 database), obtaining a list of patients with chronic diseases eligible for vaccination. We tested completeness, sensitivity, and positive predictive value (PPV) of this approach by asking a sample of 28 general practitioners (GPs) to evaluate the matching between a sublist of patients with clinical recommendations for influenza vaccination and the GPs individual subjects medical records. Results We included a total of 1,204,496 subjects with underlying medical conditions eligible to receive any of the aforementioned vaccinations. Of these, 9% were identified in all three data sources, 18% in two sources, and 73% in one source. The completeness of this automated process in identifying GPs high-risk patients eligible for influenza vaccination was 88.9% [95% confidence intervals (95% CI): 88.1–89.8%], with a sensitivity of 69.2% (95% CI: 67.7–70.6%) and a PPV of 85.7% (95% CI: 84.4–86.8%). Conclusion The high completeness of the methodology used for identifying high-risk patients in current data sources encouraged us to apply this approach for feeding the regional IIS.

Abstract
BACKGROUND Gypsies, Travellers and Roma (referred to as Travellers) are less likely to access health services, including immunisation. To improve immunisation rates, we need to understand what helps and hinders individuals in these communities in taking up immunisations. AIMS (1) Investigate the barriers to and facilitators of acceptability and uptake of immunisations among six Traveller communities across four UK cities; and (2) identify possible interventions to increase uptake of immunisations in these Traveller communities that could be tested in a subsequent feasibility study. METHODS Three-phase qualitative study underpinned by the social ecological model. Phase 1: interviews with 174 Travellers from six communities: Romanian Roma (Bristol); English Gypsy/Irish Traveller (Bristol); English Gypsy (York); Romanian/Slovakian Roma (Glasgow); Scottish Showpeople (Glasgow); and Irish Traveller (London). Focus on childhood and adult vaccines. Phase 2: interviews with 39 service providers. Data were analysed using the framework approach. Interventions were identified using a modified intervention mapping approach. Phase 3: 51 Travellers and 25 service providers attended workshops and produced a prioritised list of potentially acceptable and feasible interventions. RESULTS There were many common accounts of barriers and facilitators across communities, particularly across the English-speaking communities. Scottish Showpeople were the most similar to the general population. Roma communities experienced additional barriers of language and being in a new country. Men, women and service providers described similar barriers and facilitators. There was widespread acceptance of childhood and adult immunisation, with current parents perceived as more positive than their elders. A minority of English-speaking Travellers worried about multiple/combined childhood vaccines, adult flu and whooping cough. Cultural concerns about vaccines offered during pregnancy and about human papillomavirus were most evident in the Bristol English Gypsy/Irish Traveller community. Language, literacy, discrimination, poor school attendance, poverty and housing were identified by Travellers and service providers as barriers for some. Trustful relationships with health professionals were important and continuity of care was valued. A few English-speaking Travellers described problems of booking and attending for immunisation. Service providers tailored their approach to Travellers, particularly the Roma. Funding cuts, NHS reforms and poor monitoring challenged their work. Five 'top-priority' interventions were agreed across communities and service providers to improve the immunisation among Travellers who are housed or settled on an authorised site: (1) cultural competence training for health professionals and frontline staff; (2) identification of Travellers in health records to tailor support and monitor uptake; (3) provision of a named frontline person in general practitioner practices to provide respectful and supportive service; (4) flexible and diverse systems for booking appointments, recall and reminders; and (5) protected funding for health visitors specialising in Traveller health, including immunisation. LIMITATIONS No Travellers living on the roadside or on unofficial encampments were interviewed. We should exert caution in generalising to these groups. FUTURE WORK To include development, implementation and evaluation of a national policy plan (and practice guidance plan) to promote the uptake of immunisation among Traveller communities. STUDY REGISTRATION Current Controlled Trials ISRCTN20019630 and UK Clinical Research Network Portfolio number 15182. FUNDING This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 20, No. 72.

Abstract
Background The main goal of physical therapy is to help the patient gain a better health status. Several studies have investigated the use of reminders to prevent such failures on the patients' side. This article presents a systematic review of the literature concerning reminders in physical therapy. Methods Databases were searched until May 2017 and literatures were found from April 1992 until 2017. The literature recruitment strategy was based on applying several keywords and Medical Subject Heading (MeSH) combination running against title and abstract, including concepts such as reminder, physical therapy. The finally selected articles were categorized through reminder aspects such as how, who feedback. Data were extracted according to PRISMA guidelines. Results In 47% of studies, the reminder was sent to the patients, 29% to the physical therapists and 12% to the caretaker team. In 24% of the studies, paper-based letters were main medium for reminders while the rest were various types of media like emails and SMS mobile text messages. 35% of the articles showed positive effects of the reminders. Conclusions Many reminder methods consisted of SMS, phone calls, letters, emails and notices on the wall were used in physical therapy. Reminders may be used to improve patients' adherence to exercise programs.

Abstract
BACKGROUND Immunization rates for children and adults are rising, but coverage levels have not reached optimal goals. As a result, vaccine-preventable diseases still occur. In an era of increasing complexity of immunization schedules, rising expectations about the performance of primary care, and large demands on primary care providers, it is important to understand and promote interventions that work in primary care settings to increase immunization coverage. One common theme across immunization programs in many nations involves the challenge of implementing a population-based approach and identifying all eligible recipients, for example the children who should receive the measles vaccine. However, this issue is gradually being addressed through the availability of immunization registries and electronic health records. A second common theme is identifying the best strategies to promote high vaccination rates. Three types of strategies have been studied: (1) patient-oriented interventions, such as patient reminder or recall, (2) provider interventions, and (3) system interventions, such as school laws. One of the most prominent intervention strategies, and perhaps best studied, involves patient reminder or recall systems. This is an update of a previously published review. OBJECTIVES To evaluate and compare the effectiveness of various types of patient reminder and recall interventions to improve receipt of immunizations. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase and CINAHL to January 2017. We also searched grey literature and trial registers to January 2017. SELECTION CRITERIA We included randomized trials, controlled before and after studies, and interrupted time series evaluating immunization-focused patient reminder or recall interventions in children, adolescents, and adults who receive immunizations in any setting. We included no-intervention control groups, standard practice activities that did not include immunization patient reminder or recall, media-based activities aimed at promoting immunizations, or simple practice-based awareness campaigns. We included receipt of any immunizations as eligible outcome measures, excluding special travel immunizations. We excluded patients who were hospitalized for the duration of the study period. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by Cochrane and the Cochrane Effective Practice and Organisation of Care (EPOC) Group. We present results for individual studies as relative rates using risk ratios, and risk differences for randomized trials, and as absolute changes in percentage points for controlled before-after studies. We present pooled results for randomized trials using the random-effects model. MAIN RESULTS The 75 included studies involved child, adolescent, and adult participants in outpatient, community-based, primary care, and other settings in 10 countries.Patient reminder or recall interventions, including telephone and autodialer calls, letters, postcards, text messages, combination of mail or telephone, or a combination of patient reminder or recall with outreach, probably improve the proportion of participants who receive immunization (risk ratio (RR) of 1.28, 95% confidence interval (CI) 1.23 to 1.35; risk difference of 8%) based on moderate certainty evidence from 55 studies with 138,625 participants.Three types of single-method reminders improve receipt of immunizations based on high certainty evidence: the use of postcards (RR 1.18, 95% CI 1.08 to 1.30; eight studies; 27,734 participants), text messages (RR 1.29, 95% CI 1.15 to 1.44; six studies; 7772 participants), and autodialer (RR 1.17, 95% CI 1.03 to 1.32; five studies; 11,947 participants). Two types of single-method reminders probably improve receipt of immunizations based on moderate certainty evidence: the use of telephone calls (RR 1.75, 95% CI 1.20 to 2.54; seven studies; 9120 participants) and letters to patients (RR 1.29, 95% CI 1.21 to 1.38; 27 studies; 81,100 participants).Based on high certainty evidence, reminders improve receipt of immunizations for childhood (RR 1.22, 95% CI 1.15 to 1.29; risk difference of 8%; 23 studies; 31,099 participants) and adolescent vaccinations (RR 1.29, 95% CI 1.17 to 1.42; risk difference of 7%; 10 studies; 30,868 participants). Reminders probably improve receipt of vaccinations for childhood influenza (RR 1.51, 95% CI 1.14 to 1.99; risk difference of 22%; five studies; 9265 participants) and adult influenza (RR 1.29, 95% CI 1.17 to 1.43; risk difference of 9%; 15 studies; 59,328 participants) based on moderate certainty evidence. They may improve receipt of vaccinations for adult pneumococcus, tetanus, hepatitis B, and other non-influenza vaccinations based on low certainty evidence although the confidence interval includes no effect of these interventions (RR 2.08, 95% CI 0.91 to 4.78; four studies; 8065 participants). AUTHORS' CONCLUSIONS Patient reminder and recall systems, in primary care settings, are likely to be effective at improving the proportion of the target population who receive immunizations.

Abstract
HPV vaccine series completion rates among adolescent Hispanic females and males (~39 and 21 %, respectively) are far below the Healthy People 80 % coverage goal. Completion of the 3-dose vaccine series is critical to reducing the incidence of HPV-associated cancers. This formative study applies social marketing theory to assess the needs and preferences of Hispanic mothers in order to guide the development of interventions to increase HPV vaccine completion. We conducted 51 in-depth interviews with Hispanic mothers of adolescents to identify the key concepts of social marketing theory (i.e., the four P's: product, price, place and promotion). Results suggest that a desire complete the vaccine series, vaccine reminders and preventing illnesses and protecting their children against illnesses and HPV all influence vaccination (product). The majority of Completed mothers did not experience barriers that prevented vaccine series completion and Initiated mothers perceived a lack of health insurance and the cost of the vaccine as potential barriers. Informational barriers were prevalent across both market segments (price). Clinics are important locations for deciding to complete the vaccine series (place). They are the preferred sources to obtain information about the HPV vaccine thus making them ideal locations to deliver intervention messages, followed by television, the child's school and brochures (promotion). Increasing HPV vaccine coverage among Hispanic adolescents will reduce the rates of HPV-associated cancers and the cervical cancer health disparity among Hispanic women. This research can inform the development of an intervention to increase HPV vaccine series completion in this population.

Characteristics of mobile phone access and usage in rural and urban Guatemala: assessing feasibility of text message reminders to increase childhood immunizations. Mhealth 2018; 4:9. [PMID: 29780812 PMCID: PMC5945665 DOI: 10.21037/mhealth.2018.03.05] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2018] [Accepted: 03/21/2018] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Despite efforts to promote vaccination in low- and middle-income countries (LMICs), over 20 million infants remain under-immunized and at risk for unnecessary morbidity and mortality. Mobile health technologies, such as Short Message Service (SMS) texts, have tremendous and untapped potential for disease management. Patient reminder systems are an important mechanism for improving childhood vaccination coverage and can be easily adapted to SMS platforms. However, current research lacks an understanding of the barriers and facilitators to mHealth program design, implementation, and scale in LMICs. METHODS We analyzed survey data collected March-November 2016 at the enrollment visit from a randomized controlled trial conducted at public health clinics in urban and rural Guatemala. Participants included eligible infants 6 weeks to 6 months of age receiving the first dose of the primary immunization series. At least one parent needed to own a mobile phone and be capable of deciphering SMS. Chi-square or Fisher's exact and Student's t-test were used to assess significance levels in demographic differences to describe factors that contribute to the feasibility of using an SMS-based vaccination reminder system. RESULTS Of 1,088 families approached for enrollment, 871 were eligible and 720 (82.7%) participated with equal numbers of urban and rural children enrolled; 54 parents did not own a mobile phone with SMS capability and three parents could not use SMS. There was no significant difference between urban and rural maternal mobile phone ownership (94.4% vs. 93.3%, P=0.53), but more urban fathers owned mobile phones (72.8% vs. 47.1%, P<0.0001) and, overall, more mothers compared to fathers owned mobile phones (93.9% vs. 61.1%, P<0.0001). Most families (90.4%) chose to have reminders sent to the mother. Urban participants reported more mobile phones present in the home (P<0.0001), but rural participants reported more telephone landlines (34.7% vs. 15.6%, P<0.0001). Most participants reported a daily average of ≤5 telephone calls made (87.4%), ≤10 texts sent (91.0%), and ≤10 texts received (89.9%), with urban families reporting greater telephone usage (P=0.006, P<0.001, and P<0.001 respectively). Parents preferred to make calls over sending texts (74.7% vs. 25.3%, P<0.0001), with more urban families preferring text messaging (31.9% vs. 18.6%, P<0.0001). CONCLUSIONS Our study results provide important insight into mobile phone access, usage, and preferences for voice and text communication across rural and urban populations of an LMIC that can be used to inform future mHealth interventions. Our findings suggest that offering a combination of more traditional communication methods with newer, modern technologies may be more effective at reminding families about vaccination visits, particularly for our rural population, and that targeting mothers for mobile phone interventions may provide the greatest benefits. Overall, our study suggests that using SMS reminders in LMICs can be a feasible tool for public health interventions.

Abstract
We evaluated a national intervention of sending written reminders to parents of children lacking childhood vaccinations, using the Danish Vaccination Register (DDV). The intervention cohort included the full birth cohort of 124,189 children born in Denmark who reached the age of 2 and 6.5 years from 15 May 2014 to 14 May 2015. The reference cohort comprised 124,427 children who reached the age of 2 and 6.5 years from 15 May 2013 to 14 May 2014. Vaccination coverage was higher in the intervention cohort at 2.5 and 7 years of age. The differences were most pronounced for the second dose of the measles-mumps-rubella vaccine (MMR2) and the diphtheria-tetanus-pertussis-polio vaccine DTaP-IPV4 among the 7-year-olds, with 5.0 percentage points (95% confidence interval (CI): 4.5-5.4) and 6.4 percentage points (95% CI: 6.0-6.9), respectively. Among the 2.5 and 7-year-olds, the proportion of vaccinations in the preceding 6 months was 46% and three times higher, respectively, in the intervention cohort than the reference cohort. This study indicates a marked effect of personalised written reminders, highest for the vaccines given later in the schedule in the older cohort. In addition, the reminders increased awareness about correct registration of vaccinations in DDV.

Abstract
Background Reminder/recall systems are effective ways to improve immunization rates, but their feasibility in primary health care (PHC) settings in Nigeria has not been adequately evaluated. In this study we describe the acceptability and adaptability of immunization reminder/recall system in an urban setting in southwest Nigeria. Methods This is a descriptive report of a cluster randomized controlled trial. Four local government areas (LGAs) were randomly assigned into a cellphone reminder/recall intervention group or a usual care control group. Within each LGA, PHC centers were purposively selected to participate in the study. In each PHC center, mothers and their infants aged 0–3 months were enrolled into the two groups during the infants’ first immunization visit. Mothers (or other contact persons) in the intervention group received cellphone calls reminding them to take their child for scheduled immunizations. Follow-up of all the children lasted till the final scheduled immunization visit for each child. The intervention lasted for 13 months. Results A total of 595 mothers/infants pairs (295 in the intervention group and 300 in the control group) participated in the study. Almost all mothers (n = 590, 99.2%) had access to their own cellphone or had access to a cellphone belonging to a significant other. Ninety-eight percent (n = 584) of all mothers were willing to receive immunization reminder/recall phone calls. Eighty-seven percent (n = 2023) of all calls (n = 2324) for the reminder/recall intervention went through to the recipients and of these calls, 1948 (96.3%) were received. The mean cost of each call in US Dollars was about 5 cents. Immunization compliance rate (the receipt of required number of doses of routine vaccines at the appropriate age at recommended interval) was 79.2% among the children in intervention group and 46.4% in the control group (p < 0.001). Conclusion Results demonstrate that cellphone reminder/recall interventions to improve routine childhood immunization are feasible in PHC settings in limited-resource settings with wide cellphone coverage, such as urban areas in Nigeria. Further research to test the potential for scale up in a variety of settings is recommended. Trial registration PACTR201702002043415; Date of registration: 17 February 2017.

Abstract
Pharmacists in California are assuming a greater role as independent providers of immunizations for children and adults under Senate Bill 493 (SB 493). One of the requirements for pharmacists as independent providers of immunizations in California is that they must report their administered doses to the California immunization registry system (CAIR). The National Vaccine Advisory Committee Standards for Immunization Practice also supports this practice by recommending that all immunizing providers report vaccinations to their local and state immunization information systems (IIS). This document presents background and specific features of CAIR; best practice recommendations for the use of IIS lookup, forecasting, follow-up, and recall; and documentation features to enhance the delivery of immunization services.

Abstract
Most children received the first dose of primary vaccines on time. Timeliness of vaccination decreased with vaccine dose. Most children had appropriate intervals between doses; marked variation occurred. The quality of routine vaccination records in Wales is high. Parental report of MMR status is reliable.
Background To achieve full benefits of vaccination programmes, high uptake and timely receipt of vaccinations are required. Objectives To examine uptake and timeliness of infant and pre-school booster vaccines using cohort study data linked to health records. Methods We included 1782 children, born between 2000 and 2001, participating in the Millennium Cohort Study and resident in Wales, whose parents gave consent for linkage to National Community Child Health Database records at the age seven year contact. We examined age at receipt, timeliness of vaccination (early, on-time, delayed, or never), and intervals between vaccine doses, based on the recommended schedule for children at that time, of the following vaccines: primary (diphtheria, tetanus, pertussis (DTP), polio, Meningococcal C (Men C), Haemophilus influenzae type b (Hib)); first dose of measles, mumps and rubella (MMR); and pre-school childhood vaccinations (DTP, polio, MMR). We compared parental report with child health recorded MMR vaccination status at age three years. Results While 94% of children received the first dose of primary vaccines early or on time, this was lower for subsequent doses (82%, 65% and 88% for second and third doses and pre-school booster respectively). Median intervals between doses exceeded the recommended schedule for all but the first dose with marked variation between children. There was high concordance (97%) between parental reported and child health recorded MMR status. Conclusions Routine immunisation records provide useful information on timely receipt of vaccines and can be used to assess the quality of childhood vaccination programmes. Parental report of MMR vaccine status is reliable.

Abstract
BACKGROUND Delivery arrangements include changes in who receives care and when, who provides care, the working conditions of those who provide care, coordination of care amongst different providers, where care is provided, the use of information and communication technology to deliver care, and quality and safety systems. How services are delivered can have impacts on the effectiveness, efficiency and equity of health systems. This broad overview of the findings of systematic reviews can help policymakers and other stakeholders identify strategies for addressing problems and improve the delivery of services. OBJECTIVES To provide an overview of the available evidence from up-to-date systematic reviews about the effects of delivery arrangements for health systems in low-income countries. Secondary objectives include identifying needs and priorities for future evaluations and systematic reviews on delivery arrangements and informing refinements of the framework for delivery arrangements outlined in the review. METHODS We searched Health Systems Evidence in November 2010 and PDQ-Evidence up to 17 December 2016 for systematic reviews. We did not apply any date, language or publication status limitations in the searches. We included well-conducted systematic reviews of studies that assessed the effects of delivery arrangements on patient outcomes (health and health behaviours), the quality or utilisation of healthcare services, resource use, healthcare provider outcomes (such as sick leave), or social outcomes (such as poverty or employment) and that were published after April 2005. We excluded reviews with limitations important enough to compromise the reliability of the findings. Two overview authors independently screened reviews, extracted data, and assessed the certainty of evidence using GRADE. We prepared SUPPORT Summaries for eligible reviews, including key messages, 'Summary of findings' tables (using GRADE to assess the certainty of the evidence), and assessments of the relevance of findings to low-income countries. MAIN RESULTS We identified 7272 systematic reviews and included 51 of them in this overview. We judged 6 of the 51 reviews to have important methodological limitations and the other 45 to have only minor limitations. We grouped delivery arrangements into eight categories. Some reviews provided more than one comparison and were in more than one category. Across these categories, the following intervention were effective; that is, they have desirable effects on at least one outcome with moderate- or high-certainty evidence and no moderate- or high-certainty evidence of undesirable effects. Who receives care and when: queuing strategies and antenatal care to groups of mothers. Who provides care: lay health workers for caring for people with hypertension, lay health workers to deliver care for mothers and children or infectious diseases, lay health workers to deliver community-based neonatal care packages, midlevel health professionals for abortion care, social support to pregnant women at risk, midwife-led care for childbearing women, non-specialist providers in mental health and neurology, and physician-nurse substitution. Coordination of care: hospital clinical pathways, case management for people living with HIV and AIDS, interactive communication between primary care doctors and specialists, hospital discharge planning, adding a service to an existing service and integrating delivery models, referral from primary to secondary care, physician-led versus nurse-led triage in emergency departments, and team midwifery. Where care is provided: high-volume institutions, home-based care (with or without multidisciplinary team) for people living with HIV and AIDS, home-based management of malaria, home care for children with acute physical conditions, community-based interventions for childhood diarrhoea and pneumonia, out-of-facility HIV and reproductive health services for youth, and decentralised HIV care. Information and communication technology: mobile phone messaging for patients with long-term illnesses, mobile phone messaging reminders for attendance at healthcare appointments, mobile phone messaging to promote adherence to antiretroviral therapy, women carrying their own case notes in pregnancy, interventions to improve childhood vaccination. Quality and safety systems: decision support with clinical information systems for people living with HIV/AIDS. Complex interventions (cutting across delivery categories and other health system arrangements): emergency obstetric referral interventions. AUTHORS' CONCLUSIONS A wide range of strategies have been evaluated for improving delivery arrangements in low-income countries, using sound systematic review methods in both Cochrane and non-Cochrane reviews. These reviews have assessed a range of outcomes. Most of the available evidence focuses on who provides care, where care is provided and coordination of care. For all the main categories of delivery arrangements, we identified gaps in primary research related to uncertainty about the applicability of the evidence to low-income countries, low- or very low-certainty evidence or a lack of studies.

Abstract
BACKGROUND A key function of health systems is implementing interventions to improve health, but coverage of essential health interventions remains low in low-income countries. Implementing interventions can be challenging, particularly if it entails complex changes in clinical routines; in collaborative patterns among different healthcare providers and disciplines; in the behaviour of providers, patients or other stakeholders; or in the organisation of care. Decision-makers may use a range of strategies to implement health interventions, and these choices should be based on evidence of the strategies' effectiveness. OBJECTIVES To provide an overview of the available evidence from up-to-date systematic reviews about the effects of implementation strategies for health systems in low-income countries. Secondary objectives include identifying needs and priorities for future evaluations and systematic reviews on alternative implementation strategies and informing refinements of the framework for implementation strategies presented in the overview. METHODS We searched Health Systems Evidence in November 2010 and PDQ-Evidence up to December 2016 for systematic reviews. We did not apply any date, language or publication status limitations in the searches. We included well-conducted systematic reviews of studies that assessed the effects of implementation strategies on professional practice and patient outcomes and that were published after April 2005. We excluded reviews with limitations important enough to compromise the reliability of the review findings. Two overview authors independently screened reviews, extracted data and assessed the certainty of evidence using GRADE. We prepared SUPPORT Summaries for eligible reviews, including key messages, 'Summary of findings' tables (using GRADE to assess the certainty of the evidence) and assessments of the relevance of findings to low-income countries. MAIN RESULTS We identified 7272 systematic reviews and included 39 of them in this overview. An additional four reviews provided supplementary information. Of the 39 reviews, 32 had only minor limitations and 7 had important methodological limitations. Most studies in the reviews were from high-income countries. There were no studies from low-income countries in eight reviews.Implementation strategies addressed in the reviews were grouped into four categories - strategies targeting:1. healthcare organisations (e.g. strategies to change organisational culture; 1 review);2. healthcare workers by type of intervention (e.g. printed educational materials; 14 reviews);3. healthcare workers to address a specific problem (e.g. unnecessary antibiotic prescription; 9 reviews);4. healthcare recipients (e.g. medication adherence; 15 reviews).Overall, we found the following interventions to have desirable effects on at least one outcome with moderate- or high-certainty evidence and no moderate- or high-certainty evidence of undesirable effects.1.Strategies targeted at healthcare workers: educational meetings, nutrition training of health workers, educational outreach, practice facilitation, local opinion leaders, audit and feedback, and tailored interventions.2.Strategies targeted at healthcare workers for specific types of problems: training healthcare workers to be more patient-centred in clinical consultations, use of birth kits, strategies such as clinician education and patient education to reduce antibiotic prescribing in ambulatory care settings, and in-service neonatal emergency care training.3. Strategies targeted at healthcare recipients: mass media interventions to increase uptake of HIV testing; intensive self-management and adherence, intensive disease management programmes to improve health literacy; behavioural interventions and mobile phone text messages for adherence to antiretroviral therapy; a one time incentive to start or continue tuberculosis prophylaxis; default reminders for patients being treated for active tuberculosis; use of sectioned polythene bags for adherence to malaria medication; community-based health education, and reminders and recall strategies to increase vaccination uptake; interventions to increase uptake of cervical screening (invitations, education, counselling, access to health promotion nurse and intensive recruitment); health insurance information and application support. AUTHORS' CONCLUSIONS Reliable systematic reviews have evaluated a wide range of strategies for implementing evidence-based interventions in low-income countries. Most of the available evidence is focused on strategies targeted at healthcare workers and healthcare recipients and relates to process-based outcomes. Evidence of the effects of strategies targeting healthcare organisations is scarce.

Determinants of under-immunization and cumulative time spent under-immunized in a Quebec cohort. Vaccine 2017; 35:5924-5931. [PMID: 28882440 DOI: 10.1016/j.vaccine.2017.08.072] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2017] [Revised: 08/22/2017] [Accepted: 08/24/2017] [Indexed: 11/21/2022]
Abstract
BACKGROUND Under-immunization refers to a state of sub-optimal protection against vaccine preventable diseases. Vaccine coverage for age may not capture intentional or non-intentional spacing of vaccines in the recommended provincial immunization guidelines. We aimed to identify factors associated with coverage and under-immunization and to determine the number of days during which children were under-immunized during their first 24months of life. METHODS Secondary analysis of children ≤3years recruited through active surveillance for gastroenteritis from three Quebec pediatric emergency departments from 2012 to 2014. Vaccination status for children at least 24months of age was determined using provincial immunization guidelines. Cumulative days under-immunized were calculated for DTaP-VPI-Hib, PCV, MMR, and Men-C-C. Factors associated with up-to-date (UTD) status at 24months of life and for under-immunization ≥6months were analyzed using logistic regression. RESULTS Of 246 eligible children, 180 (73%) were UTD by 24months of life. The mean cumulative days under-immunized for MMR was 107days, for PCV 209days, for Men-C-C 145days, and for DTaP-VPI-Hib 227days. Overall, 149 children (60%) experienced delay for at least 1 vaccine. Factors associated with both an UTD status at 24months and concurrently associated with being under-immunization ≥6months, included timely initiation of immunization (OR=5.85; 95% CI: 2.80-12.22) and (OR=0.13; 95% CI: 0.07-0.24), failure to co-administer 18-month vaccines (OR=0.15; 95% CI: 0.10-0.21) and (OR=3.29; 95% CI: 2.47-4.39), and having a household with ≥3 children under 18years ((OR=0.50; 0.28-0.86) and (OR=2.99; 1.45-6.22), respectively. CONCLUSION Paired with an unexpected low level of coverage at 24months of life, the majority of our cohort also experienced a state of under-immunization for a least one vaccine. Estimates of coverage do not capture intentional or non-intentional gaps in protection from vaccine preventable illnesses. Timely preventive care should be prioritized.

Breast cancer screening outreach effectiveness: Mammogram-specific reminders vs. comprehensive preventive services birthday letters. Prev Med 2017; 102:49-58. [PMID: 28655547 PMCID: PMC5638650 DOI: 10.1016/j.ypmed.2017.06.028] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2017] [Revised: 06/19/2017] [Accepted: 06/22/2017] [Indexed: 12/28/2022]
Abstract
We compared the effectiveness of two outreach strategies on timely mammography adherence: a mammogram-specific reminder letter (sent just before a woman was due) to a birthday letter (addresses multiple preventive services and not timed around due dates). We evaluated screening mammography adherence following 79,848 mammogram-specific and 151,626 birthday letters mailed between 2002 and 2012 to women aged 40-74years enrolled in Kaiser Permanente Washington. Screening mammogram adherence was specifically tied to due date and was evaluated separately by age group and up-to-date or overdue status at the time of mailing. We used generalized estimating equations to account for correlation between repeated observations, to model the odds of screening mammography adherence by letter type. Among women up-to-date, adherence following birthday letters was 22-76% lower compared to the mammogram-specific reminders, with the greatest decreases in adherence in women aged 70-74. Birthday letters were more effective at activating screening uptake among some subgroups of overdue women aged 50-69 and most overdue women aged 70-74, but universally low adherence rates were observed in overdue women. Increasing number of recommended services for women aged 50-74 who were up-to-date resulted in 12-17% lower mammography adherence, but had no effect in women aged 40-49 or in overdue women. Birthday letters are less effective than mammogram-specific reminder letters at prompting women to undergo timely breast cancer screening, particularly among women up-to-date with screening. Birthday letters may be effective at increasing overall preventive care; however, supplemental outreach may be needed around the due date to increase timely preventive services receipt.

Tan LLJ. A review of the key factors to improve adult immunization coverage rates: What can the clinician do? Vaccine 2017; 36:5373-5378. [PMID: 28803713 DOI: 10.1016/j.vaccine.2017.07.050] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2017] [Revised: 06/13/2017] [Accepted: 07/17/2017] [Indexed: 11/16/2022]
Abstract
Adult immunization coverage rates remain low in the United States and internationally, despite obvious benefits to vaccinating and maintaining a well-vaccinated adult population. Broad policy changes are required to identify and address gaps in financing, in immunization infrastructure, and patient and provider awareness and knowledge to improve the protection of our adult and aging population from vaccine-preventable diseases. There is good evidence that efforts are now underway both within the United States and across the world to advance these policy changes. There are successful interventions that have been demonstrated to improve rates in the pediatric population that must be translated into the adult patient population to meet the critical gaps that remain at the interface of the delivery of vaccinations to adults. Improvements in overall policy will only increase adult immunization coverage rates if interventions are adapted and implemented for adult patients. Often, these same interventions will be applicable to adolescent patients as well. These interventions have been reviewed by the United States Preventive Services Task Force and recommended interventions fall into three categories: (1) Enhancing Patient Access to Vaccination; (2) Improving community/patient demand; and (3) Provider- and healthcare system-directed interventions. Specific interventions that have been demonstrated successful for the adult population include interventions such as reducing patient out-of-pocket costs for vaccinations, patient or family incentive rewards, and implementation of quality measures and quality improvement interventions. Addressing the poor performance in adult immunizations requires approaches predicated on not repeating previous efforts and will require innovative thinking to integrate multiple interventions that have been successful separately, into a holistic approach to support and automate immunization assessment, recommendation, and administration. This can then lead to increased valuation of adult and adolescent immunizations within the priorities of a healthcare system, and improvements in clinic efficiency within a practice.

Evaluating Childhood Vaccination Coverage of NIP Vaccines: Coverage Survey versus Zhejiang Provincial Immunization Information System. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:ijerph14070758. [PMID: 28696387 PMCID: PMC5551196 DOI: 10.3390/ijerph14070758] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/12/2017] [Revised: 07/07/2017] [Accepted: 07/09/2017] [Indexed: 12/16/2022]
Abstract
Vaccination coverage in Zhejiang province, east China, is evaluated through repeated coverage surveys. The Zhejiang provincial immunization information system (ZJIIS) was established in 2004 with links to all immunization clinics. ZJIIS has become an alternative to quickly assess the vaccination coverage. To assess the current completeness and accuracy on the vaccination coverage derived from ZJIIS, we compared the estimates from ZJIIS with the estimates from the most recent provincial coverage survey in 2014, which combined interview data with verified data from ZJIIS. Of the enrolled 2772 children in the 2014 provincial survey, the proportions of children with vaccination cards and registered in ZJIIS were 94.0% and 87.4%, respectively. Coverage estimates from ZJIIS were systematically higher than the corresponding estimates obtained through the survey, with a mean difference of 4.5%. Of the vaccination doses registered in ZJIIS, 16.7% differed from the date recorded in the corresponding vaccination cards. Under-registration in ZJIIS significantly influenced the coverage estimates derived from ZJIIS. Therefore, periodic coverage surveys currently provide more complete and reliable results than the estimates based on ZJIIS alone. However, further improvement of completeness and accuracy of ZJIIS will likely allow more reliable and timely estimates in future.

Abstract
Immunization for children against vaccine-preventable diseases is one of the most important health intervention method in the world, both in terms of its health impact and cost-effectiveness. Through EPI and various other programs such as the Decades of Vaccines, immunization has been improving the health of children around the world. However, this progress falls short of global immunization targets of the Global Vaccine Action Plan (GVAP). Furthermore, the African region still lags behind in immunization, and suffers from a high proportion of vaccine preventable diseases as a result. Reminders and recall for vaccination have been shown to improve health care-seeking behaviours, and have been recommended for application in routine and supplemental measles immunization activities. With mobile phones becoming more accessible in Africa, SMS vaccine reminder system has been proposed as a convenient and easily scalable way to inform caregivers of the disease and the importance of immunization, to address any concerns related to immunization safety, and to remind them of vaccination schedules and campaigns. There have been 6 published articles and 1 unpublished article on the effect of SMS reminder system for immunization in Africa. The studies done has shown that SMS vaccination reminder has led to improvements in vaccination uptakes in various metrics, whether is through the increase in vaccination coverage, decrease in dropout rates, increase in completion rate, or decrease in delay for vaccination.

Abstract
Despite the existence of a highly effective measles vaccine and the decrease in worldwide deaths from measles by more than 79% from the 2000 baseline levels, measles today remains one of the leading causes of vaccine-preventable deaths in the world. The African region is a key player in the global fight against measles. Africa has made tremendous progress in its effort to immunize children and to control the disease, increasing its regional measles vaccination coverage from 56% in 2001 to 85% in 2010. The Republic of Kenya has been a strong follower of the World Health Assembly and Measles Elimination 2020 resolutions, which aims to eliminate measles from the country. Since the beginning of the 21st century, Kenya has faced many challenges, but also aid, in the form of new innovations, in their fight against measles. In 2002, Kenya started its first SIA using A-D syringes, and from 2003-2005, GAVI funded injection safety support (INS) to Kenya, as an effort to scale-up safe injection in sub-Saharan Africa. In 2016, the Kenya introduced Measles-Rubella (MR) combined vaccine in its nationwide SIA campaign, after recognizing that rubella is a disease that must be controlled along with measles. In 2009 and 2012 SIAs, Red Cross volunteers conducted H2H visits to promote immunization as well as document information from the community with regards to immunization, including the current coverage, to campaign management levels. Case-based surveillance, using real-time PCR, measles-specific IgM detection and Epi-link were used to confirm and map measles infection during outbreaks. Alternative serosurveys such as Dried Blood Spot and Urine sample surveys were also tested in Kenya. In 2013 and 2016, two studies were also conducted in Kenya on the use of SMS reminder system for routine immunization. These studies, which showed SMS to significantly improve the vaccination coverage, paved way for use of SMS in a larger scale in Kenya.
