Interventions to improve influenza, pneumococcal polysaccharide, and hepatitis B vaccination coverage among high-risk adults: a systematic review

Effectiveness of educational interventions for healthcare workers on vaccination dialogue with older adults: a systematic review

BACKGROUND

Healthcare workers (HCW) significantly influence older adults' vaccine acceptance. This systematic review aimed to identify effective educational interventions for HCWs that could enhance their ability to engage in a dialogue with older adults on vaccination.

METHODS

Medline, Scopus, Cochrane library and grey literature were searched for comparative studies investigating educational interventions concerning older adult vaccinations. The search encompassed all languages and publication years. Analysis was performed on the outcomes 'vaccines offered or ordered' and 'vaccination rates'. Whenever feasible, a sub-analysis on publication year was conducted. Methodological limitations were assessed using the RoB 2 for RCTs and the GRADE checklist for non-randomized studies. Study outcomes were categorized according to the four-level Kirkpatrick model (1996) for effectiveness: reaction, learning, behaviour, and results.

RESULTS

In total, 48 studies met all inclusion criteria. Most studies included reminder systems signalling HCWs on patients due for vaccination. Other interventions included seminars, academic detailing and peer-comparison feedback. Four articles reporting on the reaction-level indicated that most HCWs had a favourable view of the intervention. Two of the six articles reporting on the learning-level observed positive changes in attitude or knowledge due to the intervention. Seventeen studies reported on the behaviour-level. An analysis on eleven out of seventeen studies focusing on vaccines 'ordered' or 'offered' outcomes suggested that tailored reminders, particularly those implemented before 2000, were the most effective. Out of 34 studies reporting on the result-level, 24 were eligible for analysis on the outcome 'vaccination rate', which showed that compared to usual care, multicomponent interventions were the most effective, followed by tailored reminders, especially those predating 2000. Nonetheless, tailored reminders often fell short compared to other interventions like standing orders or patient reminders. In both the behaviour-level and result-level 'education only' interventions frequently underperformed relative to other interventions. Seventeen out of the 27 RCTs, and seven of the 21 non-randomized studies presented a low-to-medium risk for bias in the studies' findings.

CONCLUSIONS

Tailored reminders and multicomponent interventions effectively assist HCWs in addressing vaccines with older adults. However, education-only interventions appear to be less effective compared to other interventions rates, attitude, knowledge.

Barriers and facilitators of vaccine hesitancy for COVID-19, influenza, and pertussis during pregnancy and in mothers of infants under two years: An umbrella review

BACKGROUND

Vaccination during pregnancy has been repeatedly demonstrated to be safe and effective in protecting against infection and associated harms for the mother, developing baby, and subsequent infant. However, maternal vaccination uptake remains low compared to the general population.

OBJECTIVES

An umbrella review to explore the barriers and facilitators to Influenza, Pertussis and COVID-19 vaccination during pregnancy and within 2 years after childbirth, and to inform interventions to encourage uptake (PROSPERO registration number: CRD42022327624).

METHODS

Ten databases were searched for systematic reviews published between 2009 and April 2022 exploring the predictors of vaccination or effectiveness of interventions to improve vaccination for Pertussis, Influenza, or COVD-19. Both pregnant women and mothers of infants under two years were included. Barriers and facilitators were organised using the WHO model of determinants of vaccine hesitancy through narrative synthesis, the Joanna Briggs Institute checklist assessed review quality, and the degree of overlap of primary studies was calculated.

RESULTS

19 reviews were included. Considerable overlap was found especially for intervention reviews, and the quality of the included reviews and their primary studies varied. Sociodemographic factors were specifically researched in the context of COVID-19, exerting a small but consistent effect on vaccination. Concerns around the safety of vaccination particularly for the developing baby were a main barrier. While key facilitators included recommendation from a healthcare professional, previous vaccination, knowledge around vaccination, and communication with and support from social groups. Intervention reviews indicated multi-component interventions involving human interaction to be most effective.

CONCLUSION

The main barriers and facilitators for Influenza, Pertussis and COVID-19 vaccination have been identified and constitute the foundation for policy development at the international level. Ethnicity, socioeconomic status, concerns about vaccine safety and side effects, and lack of healthcare professionals' recommendations, are the most relevant factors of vaccine hesitancy. Adapting educational interventions to specific populations, person-to-person interaction, healthcare professionals' involvement, and interpersonal support are important strategies to improve uptake.

Overcoming barriers and enhancing facilitators to COVID-19 vaccination in the Hispanic community

BACKGROUND

Hispanic communities in the United States have been disproportionately affected by COVID-19 infections, hospitalizations, and death. Vaccination against COVID-19 is critical for controlling the pandemic; however, higher levels of vaccine hesitancy and reduced vaccine uptake constrain efforts to mitigate the pandemic and could perpetuate disparities. The aim of this study was to understand barriers and facilitators to COVID-19 vaccination through the lived experiences of Hispanic persons living in Arkansas.

METHODS

Bilingual community partners facilitated recruitment, made initial contact with potential participants, and scheduled interviews and focus groups. Individuals over the age of 18 who identified as Hispanic were invited to participate. Data was collected from 49 participants in 10 individual interviews and five focus groups. This study used a qualitative exploratory design and thematic analysis.

RESULTS

Five themes emerged as barriers for Hispanic participants: technological literacy and pre-registration, language and literacy, health insurance/health care costs, immigration status, and location and transportation. Three themes emerged as facilitators: workplace vaccination, health care provider recommendations, and engagement through schools.

CONCLUSIONS

Based on the findings of this study, a multi-modal and flexible approach will be implemented by the authors to address barriers to vaccine uptake among the Hispanic community in Arkansas.

Severe mental disorders and vaccinations - a systematic review

OBJECTIVES

People with severe mental illnesses (SMI: schizophrenia, depressive disorder, bipolar disorder) have a high risk of being infected by viruses and suffer a more severe infection illness course than the general population. The aim of this literature review was to elucidate rates as well as immunogenicity and side effects of vaccinations in SMI.

METHODS

All studies in the English or German language, which investigated either prevalence rates or effects of vaccinations in the target groups, were systematically searched in the databank PubMed by three independent authors using the PRISMA guidelines and discussed in more detail.

RESULTS

The search found 24 studies reporting epidemiological data and 16 investigating immunogenicity of vaccinations. The results on prevalence rates, antibody production, inflammation response and side effects were inconsistent. About interactions with psychotropic medication, only two studies on clozapine were found.

CONCLUSIONS

Only a few trials with heterogeneous samples have investigated prevalence and effects of vaccinations in SMI. Sex, age and other factors such as somatic comorbidities and special vaccination programmes have not been considered continuously and may influence rates as well. As individuals with SMI might be at special risk, further research on the willingness to be vaccinated as well as efficacy of vaccinations is needed.

Willingness to be vaccinated against COVID-19 is equal in individuals with affective disorders and healthy controls

Affective disorders such as major depressive disorder and bipolar disorder are associated with higher infection rates and a more severe course of coronavirus disease (COVID-19). In turn, COVID-19 could trigger mental disease relapse. Vaccinations lead to a reduction of infections and the prevention of severe courses. This work aims to survey the willingness of individuals with affective disorders to get vaccinated and concerns about vaccinations.

METHODS

An online study (April-May 2021) assessed the current infection and vaccination rate amongst individuals with affective disorder in Austria by surveying attitudes towards the vaccination, the willingness to get vaccinated soon and possible reasons for decision. The analyses included 59 individuals with affective disorders and 59 healthy controls, matched for sex and age.

RESULTS

There was an overall high willingness to get vaccinated against COVID-19. Individuals with affective disorders were more skeptical about vaccinations in general but there was no significant difference between the groups in the willingness to get vaccinated against COVID-19. In both groups reasons for waiting were mainly fears of acute and/or long-term side effects and the fast development of the vaccines.

LIMITATIONS

It was a cross sectional design. Due to the online design, no objective rating of current psychopathological symptoms was assessed. Willingness to get vaccinated in general and against COVID-19 in particular were self-created variables, whereas item statistics and factor analysis were conducted.

DISCUSSION

Because of the higher risk for individuals with affective disorders, preventive strategies like vaccinating should be promoted in this group. It is important to help individuals with AD to overcome barriers such as negative beliefs and concerns about acute and/or long-term side effects.

Changing attitudes towards annual influenza vaccination amongst staff in a Tertiary Care Irish University Hospital

Background

Healthcare workers are encouraged annually to get vaccinated against influenza. This year in view of COVID-19 pandemic, attitudes of HCWs towards vaccination are particularly important. A cross-sectional study was completed to understand how to best encourage and facilitate the vaccination of HCWs based on the previous years’ findings.

Methods

An online survey was disseminated to all hospital staff via electronic channels. The clinical audit sphinx software was used for data collection and analysis.

Results

The total number of responses was n = 728, almost double the rate from 2018 (N = 393). A total of 78% (N = 551) of participants were vaccinated last year. A total of 94% (N = 677) of participants reported their intention to be vaccinated this year. The main barriers listed were being unable to find time (32%, N = 36), side effects (30%, N = 33) and thinking that it does not work (21%, N = 23). The most popular suggestions for how to increase uptake were more mobile immunisation clinics (72%, N = 517) and more information on the vaccine (50%, N = 360). A total of 82% of participants (N = 590) agreed that healthcare workers should be vaccinated, with 56% (N = 405) agreeing that it should be mandatory. Of the participants who were not vaccinated last year (N = 159), 40% (N = 63) agreed that COVID-19 had changed their opinion on influenza immunisation with a further 11% (N = 18) strongly agreeing.

Discussion

In light of the increasing number of survey participants, more staff were interested in flu vaccination this year than ever before. The COVID-19 pandemic has had some influence on staff’s likelihood to be vaccinated. Feasibility of immunisation and education posed the largest barriers to HCW vaccination.

Facilitating pneumococcal vaccination among high-risk adults: Impact of an assertive communication training program for community pharmacists

BACKGROUND

Community pharmacies are vital access points to provide a range of vaccines to adults, including pneumococcal vaccines; however, despite a growth in the number of vaccines given at these sites, the most recent rates of adults being immunized against pneumococcal disease remain below the goals set by Health People 2020. Low patient awareness is a leading reason for suboptimal vaccination rates, suggesting that a need exists to improve provider communication in recommending pneumococcal vaccination in high-risk adults.

OBJECTIVES

To evaluate the impact of a communication training program to improve pharmacist promotion of the pneumococcal vaccine among high-risk adults in Tennessee.

METHODS

A multiphase training program was initiated in partnership with 2 regions of a nationwide community pharmacy chain (n = 100) focusing on improving evidence-based, presumptive recommendations related to pneumococcal vaccination. All locations were randomized to one of 3 arms on the basis of training intensity: (1) no training; (2) online training only; and (3) online and in-person simulation training. The program focused on improving evidence-based, pharmacist vaccine recommendations using health behavior theories, sales techniques, and improvisation provided through online and in-person simulation training. Changes in vaccinations (compared with the same 6-month period in the previous year) and provider self-efficacy were evaluated by Mann-Whitney U tests, chi-square tests, and general linear models.

RESULTS

Completing the full training program led to nominal changes in pharmacist self-efficacy across the 6 items measured (P > 0.05). Overall counts of all pneumococcal vaccines were lower (-11.3%) across all stores in the period after training; however, a small increase (2.1%) was observed in the stores that underwent the full training, versus changes of -22.0% (P = 0.084) and -9.4% (P = 0.199) in control and online-only training comparisons, respectively.

CONCLUSIONS

Pharmacists' vaccine-related self-efficacy may be improved through an evidence-based communication training program, but a more holistic focus on all recommended adult vaccines may be necessary to realize meaningful improvements.

Physicians' Use of Evidence-Based Strategies to Increase Adult Vaccination Uptake

INTRODUCTION

This study assesses the following among primary care physicians: (1) the use of evidence-based strategies to improve adult vaccination rates, (2) the number of strategies employed simultaneously, and (3) characteristics associated with assessing adult vaccinations at each visit.

METHODS

An internet and mail survey was administered between December 2015 and January 2016 on primary care physicians designed to be representative of the American College of Physicians and American Academy of Family Physicians memberships. Data analysis was conducted in 2019.

RESULTS

The response rate was 66% (617 of 935); 94% reported using electronic health records. Standing orders (84%) and electronic provider reminders at a visit (61%) were the most common strategies reported for influenza vaccine. Electronic provider reminders at a visit (53%) and recording a vaccination in an immunization registry (32%) were the most common strategies reported for all noninfluenza vaccines. Most physicians reported using 2 or more strategies, although this was more common for influenza (74%) than for noninfluenza (62%) vaccines. In multivariable analysis, physicians who reported assessing adult vaccinations at every patient visit were more likely to work in practices where decisions about purchasing and handling vaccines were made at a larger system level (RR=1.20, 95% CI=1.04,1.40), and they reported using electronic provider reminders (RR=1.38, 95% CI=1.15, 1.69) and standing orders (RR=1.45, 95% CI=1.21, 1.75) for all noninfluenza adult vaccines.

CONCLUSIONS

Several strategies are being used to increase adult vaccination, particularly for the influenza vaccine. Investment in implementing standing orders and electronic clinical decision support for all routine adult vaccinations could help facilitate assessment of adult vaccinations at each visit and potentially improve adult vaccination rates.

Multiple mail reminders to increase adherence to influenza vaccination

INTRODUCTION

Different interventions have been proposed to reinforce the use of the influenza vaccine. The use of reminders, whether through letters, phone calls, pamphlets or technological applications, among others, has stood out among those aimed at increasing ad-herence to treatment. However, its effectiveness is not clear. In this summary, which is part of a series of reminder evaluations, we assess the use of multiple mail reminders.

METHODS

We conducted a search in Epistemonikos, the largest database of systematic health reviews, which is maintained by screening multiple sources of information, including MEDLINE, EMBASE, Cochrane, among others. We extracted the data from the identified reviews, analyzed the data from the primary studies, performed a meta-analysis and prepared a summary table of the results using the GRADE method.

RESULTS AND CONCLUSIONS

We identified eight systematic reviews including 35 primary studies, of which four analyze the use of more than one letter as a reminder. We conclude that the use of multiple mail reminders probably increase adherence to influenza vaccination in patients over 60; while it may make little or no difference in children under 6 years, but the certainty of the evidence is low.

Using the Tailoring Immunization Programmes guide to improve child immunisation in Umina, New South Wales: we could still do better

In the Central Coast Local Health District of New South Wales, Australia, childhood immunisation (CI) rates are around 95%, but pockets of underimmunisation exist. Using the World Health Organization's Tailoring Immunization Programmes, we identified areas of potential low vaccine coverage using Australian Immunisation Register (AIR) data (2016-18) and investigated factors that influence CI. Individual and group interviews with carers, community members and service providers (n=52 participants) were conducted. Data were analysed thematically and the themes presented to stakeholders for feedback before finalisation. During 2018, Umina had 218 children at least 1 month overdue for at least one vaccination. Five themes emerged: (1) broader socioeconomic factors may apply pressures that influence CI; (2) parents largely supported immunisation and knew of its benefits to their children and the community; (3) immunisation service providers are committed, experienced and collaborate with community partners; (4) there is potential to increase access to free immunisation services in Umina; and (5) AIR data and reminder systems could be better used to inform service delivery and prompt parents before immunisations are due. This study identified opportunities to improve CI coverage in Umina and new information useful in developing a tailored immunisation strategy. Awareness of the pressures socioeconomic factors may have on families could help plan and deliver supportive primary health care that includes equitable access to immunisation.

Development and Validation of a Clinical Prediction Tool for Seasonal Influenza Vaccination in England

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.

Effects of multicomponent primary care-based intervention on immunization rates and missed opportunities to vaccinate adults

Background

Adult immunization rates are below Healthy People 2020 targets. Our objective was to evaluate the effectiveness of a multicomponent intervention to improve adult immunization rates.

Methods

This prospective interventional before-and-after non-randomized study was conducted through the American Academy of Family Physicians National Research Network with 43 primary care physicians from a large multi-specialty healthcare organization (multicomponent intervention group n = 23; comparator group n = 20) in the United States. The multicomponent intervention included provider reminders, quarterly provider-level performance reports, provider education, patient visual aid materials, and standing orders on adult pneumococcal, influenza, and zoster immunizations. We assessed individual and comparative provider-level vaccination rates and missed opportunities detailing concordance with targets established by Healthy People 2020 for pneumococcal, influenza, and zoster immunizations.

Results

Vaccination rates increased after 12 months in intervention and comparator groups respectively for: a). influenza from 44.4 ± 16.7 to 51.3% ± 12.9% (by 6.9 percentage points, p = 0.001) and from 35.1 ± 19.1 to 41.3% ± 14.2%, (by 6.2 percentage points, p = 0.01); b). pneumococcal vaccinations in older adults from 62.8 ± 17.6 to 81.4% ± 16.6% (by 18.6 percentage points, for p < 0.0001) and from 55.9 ± 20.0 to 72.7% ± 18.4% (by 16.7 percentage points, p < 0.0001); and c). zoster from 37.1 ± 13.4 to 41.9% ± 13.1% (by 4.8 percentage points, p < 0.0001) and from 35.0 ± 18.7 to 42.3% ± 20.9% (7.3 percentage points, p = 0.001). Pneumococcal vaccinations in adults at risk did not change from baseline in intervention group (35.7 ± 19.6 to 34.5% ± 19.0%, p = 0.3) and improved slightly in comparator group (24.3 ± 20.1 to 28.2% ± 20.0%, p = 0.003). Missed opportunities reduced after 12 months, most noticeably, for: a). for influenza from 57.7 to 48.6% (by 9.1 percentage points, p < 0.0001) and from 69.7 to 59.6% (by 10.1 percentage points, p < 0.0001); b). pneumococcal vaccinations in older adults from 18.1 to 11.5% (by 6.6 percentage points p < 0.0001) and from 24.6 to 20.4% (by 4.3 percentage points, p < 0.0001) in intervention and comparator groups respectively.

Conclusions

Multicomponent interventions show promise in improving vaccination rates and reducing missed opportunities in older adults for pneumococcal and zoster vaccines and vaccination against influenza. Provider reminders remain the most effective strategy when delivered either as a component of these interventions or alone.

The effectiveness of financial intervention strategies for reducing caesarean section rates: a systematic review

Background

The increasing trend of Caesarean section (CS) in childbirth has become a global public health challenge. Previous studies have proposed financial intervention strategies for reducing CS rates by limiting caesarean delivery on maternal request (CDMR). This study synthesizes such strategies while evaluating their effectiveness.

Methods

The sources of data for this study are Cochrane Library, PubMed, EMBASE, and CINAHL. The publication period included in this study is from January 1991 to November 2018. The financial intervention strategies are divide into two categories: healthcare provider interventions and patient interventions. Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I) was employed to assess the risk of bias of included studies. The outcome of each study was evaluated with Grades of Recommendation, Assessment, Development and Evaluation (GRADE) through the GRADEpro Guideline Development Tool software.

Results

Nine studies were included in this systematic review: five with high certainty evidence (HCE), three with moderate certainty evidence (MCE), and one with low certainty evidence (LCE). Of the nine studies, seven are centered on the effect of provider-side interventions. Three of the HCE studies found that the diagnosis-related group payment system, risk-adjusted capitation, and equalizing fee for both facilities and physicians were effective intervention strategies. One HCE and one MCE study showed that only equalizing facility fees between vaginal and CS deliveries in healthcare service settings had no significant effect on reducing the CS rate. The MCE study showed that case payment had a negative effect on reducing the CS rates. One LCE study revealed that the effect of a global budget system was uncertain, and one HCE and one MCE study focused on combining both provider and patient-side interventions. However, equalizing fees for vaginal and CS deliveries and a co-payment policy for CDMRs failed to reduce the CS rate.

Conclusions

The effectiveness of risk-adjusted payment methods appears promising and should be the subject of further research. Financial interventions should consider stakeholders’ characteristics, especially the personal interests of doctors. Finally, high-quality randomized control trials and comparative studies on different financial intervention methods are needed to confirm or refute previous studies’ outcomes.

Reporting quality of systematic reviews of interventions aimed at improving vaccination coverage: compliance with PRISMA guidelines

Systematic reviews have become increasingly important for informing clinical practice and policy; however, little is known about the reporting characteristics and quality of SRs of interventions to improve immunization coverage in different settings. The aim of this study was to assess the reporting quality of systematic reviews of interventions aimed at improving vaccination coverage using the recommended Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guideline.PubMed and Cochrane Library were searched to identify SRs of interventions to improve immunization coverage, indexed up to May 2016. Two authors independently screened the search output, assessed study eligibility, and extracted data from eligible SRs using a 27-item data collection form derived from PRISMA. Discrepancies in reviews assessments were resolved by discussion and consensus.A total of 57 reviews were included in this study with a mean percentage of applicable PRISMA items that were met across all studies of 66% (range 19-100%) and median compliance of 70%. 39 out of the 57 reviews were published after the release of the PRISMA statement in 2009. Highest compliance was observed in items related to the "description of rational", "description of eligibility criteria", "synthesis of results" and "provision of a general interpretation of the results" (items #3, #6, #14 and #26, respectively). Compliance was poorest in the items "describing summary of evidence" (item 24, 19%), "describing indication of review protocol and registration" (item 5, 26%) and "describing results of risk of bias across studies (item 22, 33%).The overall reporting quality of systematic reviews of interventions to improve vaccination coverage requires significant improvement. There remains a need for additional research targeted at addressing potential barriers to compliance and strategies to improve compliance with PRISMA guideline.

A multi-site case study of community-clinical linkages for promoting HPV vaccination

Human papillomavirus (HPV) vaccination rates in the U.S. are suboptimal, requiring innovative partnerships between community and clinical entities to remedy this issue. A rigorous evaluation of HPV-related community-clinical linkages (CCLs) was conducted to understand their components, processes, and outcomes to increase HPV vaccination. Cancer Prevention and Control Research Network (CPCRN) investigators explored CCLs in their communities employing an iterative, case study approach. Information describing nine CCLs on HPV vaccination was collected from representatives from the community organization and clinical setting. Thematic content analysis was used to analyze and interpret data. Five CCLs included a federally qualified health center as the clinical partner, and five included a non-profit organization as the community partner. Five reflected clinically focused integration wherein engagement occurs in the community but vaccine delivery and follow-up occur in the clinical setting. The main impetus was the need to improve HPV vaccination and a community's strong interest in preventing cancer. Noted critical components were a designated person to support the CCL and funding. Results will guide HPV vaccination promotion, education, and intervention efforts. CCLs provide an opportunity to study the adaption, integration, and enhancement of evidence-based approaches to increase HPV vaccination.

Vaccination differences among U.S. adults by their self-identified sexual orientation, National Health Interview Survey, 2013-2015

Introduction

Very few studies have explored the associations between self-identified sexual orientation and comprehensive vaccination coverage. Most of the previous studies that reported health disparities among lesbian, gay and bisexual populations were not based on a nationally representative sample of U.S. adults, limiting the generalizability of the findings. Starting in 2013, the National Health Interview Survey (NHIS) included questions to ascertain the adult’s self-identified sexual orientation that allowed national level vaccination estimation by sexual orientation. This study examined associations of self-reported vaccination coverage for selected vaccines among U.S. adults by their sexual orientation.

Methods

We analyzed combined data from 2013–2015 NHIS, a nationally representative probability-based health survey of the noninstitutionalized U.S. population ≥18 years. For vaccines other than influenza, weighted proportions were calculated. Influenza coverage was calculated using the Kaplan-Meier procedure. Multivariable logistic regression models were used to calculate adjusted prevalence differences for each vaccine overall and stratified by sexual orientation and to identify factors independently associated with vaccination.

Results

Significant differences were observed by sexual orientation for self-reported receipt of human papillomavirus (HPV), hepatitis A (HepA), hepatitis B (HepB), and influenza vaccination. Bisexual females (51.6%) had higher HPV coverage than heterosexual females (40.2%). Gay males (40.3% and 53.6%, respectively) had higher HepA and HepB coverage than heterosexual males (25.4% and 32.6%, respectively). Bisexual females (33.9% and 58.5%, respectively) had higher HepA and HepB coverage than heterosexual females (23.5% and 38.4%, respectively) and higher HepB coverage than lesbian females (45.4%). Bisexual adults (34.1%) had lower influenza coverage than gay/lesbian (48.5%) and heterosexual adults (43.8%). Except for the association of having self-identified as gay/lesbian orientation with greater likelihood of HepA, HepB, and influenza vaccination, sexual orientation was not associated with higher or lower likelihood of vaccination. Health status or other behavioral characteristics studied had no consistent relationship with vaccination among all populations.

Conclusion

Differences were identified in vaccination coverage among the U.S. adult population by self-reported sexual orientation. This study is the first to assess associations of sexual orientation with a comprehensive list of vaccinations. Findings from this study can serve as a baseline for monitoring changes over time. All populations could benefit from improved vaccination.

Interventions to increase influenza vaccination rates of those 60 years and older in the community

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.

Local-Level Adult Influenza and Pneumococcal Vaccination Disparities: Chicago, Illinois, 2015-2016

OBJECTIVES

To investigate local-level adult influenza and pneumococcal vaccination disparities to inform targeted interventions.

METHODS

Questions on influenza and pneumococcal vaccination uptake were included in a door-to-door community-based representative survey conducted in 10 Chicago, Illinois, neighborhoods in 2015 and 2016. A total of 1543 adults completed the survey, including 172 adults aged 65 years or older. We calculated adult influenza (≥ 18 years) and pneumococcal (≥ 65 years) vaccination coverage by community area and respondent characteristics.

RESULTS

We observed significant differences in pneumococcal vaccination coverage between community areas (range = 18%-91%). Influenza vaccination coverage differed by gender, age, insurance coverage, acculturation, and confidence or trust in physician. Non-Hispanic Blacks were more likely to be vaccinated when they had higher confidence or trust in their physician (45% vs 20%; P < .01). Mexicans who reported less acculturation were more likely to be vaccinated than were Mexicans who were more acculturated (41% vs 27%; P = .02).

CONCLUSIONS

Striking disparities between neighborhoods and racial/ethnic groups in adult influenza and pneumococcal vaccination coverage highlight the need for improved local-level immunization coverage data.

Computer-generated reminders delivered on paper to healthcare professionals: effects on professional practice and healthcare outcomes

BACKGROUND

Clinical practice does not always reflect best practice and evidence, partly because of unconscious acts of omission, information overload, or inaccessible information. Reminders may help clinicians overcome these problems by prompting them to recall information that they already know or would be expected to know and by providing information or guidance in a more accessible and relevant format, at a particularly appropriate time. This is an update of a previously published review.

OBJECTIVES

To evaluate the effects of reminders automatically generated through a computerized system (computer-generated) and delivered on paper to healthcare professionals on quality of care (outcomes related to healthcare professionals' practice) and patient outcomes (outcomes related to patients' health condition).

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, six other databases and two trials registers up to 21 September 2016 together with reference checking, citation searching and contact with study authors to identify additional studies.

SELECTION CRITERIA

We included individual- or cluster-randomized and non-randomized trials that evaluated the impact of computer-generated reminders delivered on paper to healthcare professionals, alone (single-component intervention) or in addition to one or more co-interventions (multi-component intervention), compared with usual care or the co-intervention(s) without the reminder component.

DATA COLLECTION AND ANALYSIS

Review authors working in pairs independently screened studies for eligibility and abstracted data. For each study, we extracted the primary outcome when it was defined or calculated the median effect size across all reported outcomes. We then calculated the median improvement and interquartile range (IQR) across included studies using the primary outcome or median outcome as representative outcome. We assessed the certainty of the evidence according to the GRADE approach.

MAIN RESULTS

We identified 35 studies (30 randomized trials and five non-randomized trials) and analyzed 34 studies (40 comparisons). Twenty-nine studies took place in the USA and six studies took place in Canada, France, Israel, and Kenya. All studies except two took place in outpatient care. Reminders were aimed at enhancing compliance with preventive guidelines (e.g. cancer screening tests, vaccination) in half the studies and at enhancing compliance with disease management guidelines for acute or chronic conditions (e.g. annual follow-ups, laboratory tests, medication adjustment, counseling) in the other half.Computer-generated reminders delivered on paper to healthcare professionals, alone or in addition to co-intervention(s), probably improves quality of care slightly compared with usual care or the co-intervention(s) without the reminder component (median improvement 6.8% (IQR: 3.8% to 17.5%); 34 studies (40 comparisons); moderate-certainty evidence).Computer-generated reminders delivered on paper to healthcare professionals alone (single-component intervention) probably improves quality of care compared with usual care (median improvement 11.0% (IQR 5.4% to 20.0%); 27 studies (27 comparisons); moderate-certainty evidence). Adding computer-generated reminders delivered on paper to healthcare professionals to one or more co-interventions (multi-component intervention) probably improves quality of care slightly compared with the co-intervention(s) without the reminder component (median improvement 4.0% (IQR 3.0% to 6.0%); 11 studies (13 comparisons); moderate-certainty evidence).We are uncertain whether reminders, alone or in addition to co-intervention(s), improve patient outcomes as the certainty of the evidence is very low (n = 6 studies (seven comparisons)). None of the included studies reported outcomes related to harms or adverse effects of the intervention.

AUTHORS' CONCLUSIONS

There is moderate-certainty evidence that computer-generated reminders delivered on paper to healthcare professionals probably slightly improves quality of care, in terms of compliance with preventive guidelines and compliance with disease management guidelines. It is uncertain whether reminders improve patient outcomes because the certainty of the evidence is very low. The heterogeneity of the reminder interventions included in this review also suggests that reminders can probably improve quality of care in various settings under various conditions.

Role of non-traditional locations for seasonal flu vaccination: Empirical evidence and evaluation

This study investigated the role of non-traditional locations in the decision to vaccinate for seasonal flu. We measured individuals' preferred location for seasonal flu vaccination by examining the National H1N1 Flu Survey (NHFS) conducted from late 2009 to early 2010. Our econometric model estimated the probabilities of possible choices by varying individual characteristics, and predicted the way in which the probabilities are expected to change given the specific covariates of interest. From this estimation, we observed that non-traditional locations significantly influenced the vaccination of certain individuals, such as those who are high-income, educated, White, employed, and living in a metropolitan statistical area (MSA), by increasing the coverage. Thus, based on the empirical evidence, our study suggested that supporting non-traditional locations for vaccination could be effective in increasing vaccination coverage.

National and State-Specific Shingles Vaccination Among Adults Aged ≥60 Years

INTRODUCTION

Shingles (herpes zoster) causes substantial morbidity, especially among older adults. The shingles vaccine has been recommended for people aged ≥60 years since 2006. This study assessed recent shingles vaccination at national and state levels among adults aged ≥60 years.

METHODS

The 2014 Behavioral Risk Factor Surveillance System data were analyzed in 2015 to assess shingles vaccination coverage among adults aged ≥60 years at national and state levels. Multivariable logistic regression and predictive marginal models identified factors independently associated with vaccination.

RESULTS

Shingles vaccination coverage among adults aged ≥60 years was 31.8% (95% CI=31.4%, 32.2%). Among states, shingles vaccination coverage ranged from 17.8% (95% CI=15.8%, 20.0%) in Mississippi to 46.6% (95% CI=44.3%, 48.8%) in Vermont, with a median of 33.3%. Coverage was <25% in four states and >40% in nine states. For all states, coverage was significantly higher among non-Hispanic whites compared with non-white races except for Oregon, with coverage differences ranging from -33.2% in the District of Columbia to 0.9% in Oregon and a median of -16.0%. Characteristics independently associated with vaccination were age, race/ethnicity, sex, education, employment status, household income, region, perceived health status, health insurance status, personal healthcare provider, routine checkup status, and whether reporting that cost was a barrier to seeing a doctor.

CONCLUSIONS

Coverage varied dramatically by state. State-level comparisons may aid in designing tailored intervention programs through sharing of best practices. Strategies are needed to mitigate financial barriers for both provider and patients, improve awareness, and increase provider recommendation of the vaccine.

Stimulating Influenza Vaccination via Prosocial Motives

Objective

Americans do not vaccinate nearly enough against Influenza (flu) infection, despite severe health and economic burden of influenza. Younger people are disproportionately responsible for transmission, but do not suffer severely from the flu. Thus, to achieve herd immunity, prosocial motivation needs to be a partial driver of vaccination decisions. Past research has not established the causal role of prosociality in flu vaccination, and the current research evaluates such causal relationship by experimentally eliciting prosociality through messages about flu victims.

Methods

In an experimental study, we described potential flu victims who would suffer from the decision of others to not vaccinate to 3952 Internet participants across eight countries. We measured sympathy, general prosociality, and vaccination intentions. The study included two identifiable victim conditions (one with an elderly victim and another with a young victim), an unidentified victim condition, and a no message condition.

Results

We found that any of the three messages increased flu vaccination intentions. Moreover, this effect was mediated by enhanced prosocial motives, and was stronger among people who were historical non-vaccinators. In addition, younger victim elicited greater sympathy, and describing identifiable victims increased general sympathy and prosocial motives.

Conclusions

These findings provide direct experimental evidence on the causal role of prosocial motives in flu vaccination, by showing that people can be prompted to vaccinate for the sake of benefiting others.

Increasing the coverage of influenza vaccination in healthcare workers: review of challenges and solutions

Seasonal influenza vaccine uptake rate of healthcare workers (HCWs) varies widely from <5% to >90% worldwide. Perception of vaccine efficacy and side-effects are conventional factors affecting the uptake rates. These factors may operate on a personal and social level, impacting the attitudes and behaviours of HCWs. Vaccination rates were also under the influence of the occurrence of other non-seasonal influenza pandemics such as avian influenza. Different strategies have been implemented to improve vaccine uptake, with important ones including the enforcement of the local authority's recommendations, promulgation of practice guidelines, and mandatory vaccination polices. Practised in some regions in North America, mandatory policies have led to higher vaccination rate, but are not problem-free. The effects of conventional educational programmes and campaigns are in general of modest impact only. Availability of convenient vaccination facilities, such as mobile vaccination cart, and role models of senior HCWs receiving vaccination are among some strategies which have been observed to improve vaccination uptake rate. A multi-faceted approach is thus necessary to persuade HCWs to participate in a vaccination programme, especially in areas with low uptake rate.

The Saudi Thoracic Society guidelines for influenza vaccinations

Influenza viruses are responsible for the influenza outbreaks that lead to significant burden and cause significant morbidity and mortality worldwide. Based on the core proteins, influenza viruses are classified into three types, A, B, and C, of which only A and B cause significant human disease and so the vaccine is directed against these two subtypes only. The effectiveness of the vaccine depends on boosting the immune system against the serotypes included within it. As influenza viruses undergo periodic changes in their antigen, the vaccine is modified annually to ensure susceptibility. In contrast to other countries, Saudi Arabia faces a unique and challenging situation due to Hajj and Umrah seasons, when millions of people gather at the holy places in Mecca and Madinah, during which influenza outbreaks are commonly found. Such challenges making the adoption of strict vaccination strategy in Saudi Arabia is of great importance. All efforts were made to develop this guideline in an easy-to-read form, making it very handy and easy to use by health care workers. The guideline was designed to provide recommendations for problems frequently encountered in real life, with special consideration for special situations such as Hajj and Umrah seasons and pregnancy.

Interventions to increase the uptake of seasonal influenza vaccination among pregnant women: A systematic review

BACKGROUND

Pregnant women and their infants under 6 months of age infected with influenza have a high risk of serious morbidity and mortality. Influenza vaccine during pregnancy offers 3-for-1 benefits to pregnant women, fetuses and newborn infants. Current vaccination uptake rates during pregnancy, however, are often lower than other high-risk groups and the general population.

METHODS

We systematically reviewed evidence on the effectiveness of interventions to improve influenza vaccination coverage in pregnant women. Risk differences (RDs) were calculated from the included studies.

RESULTS

Eleven studies were included in the review, of which four were randomized controlled trials (RCTs). Three cohort studies assessed provider-focused interventions while four RCTs and one cohort study evaluated pregnant women-focused interventions. Two cohort studies and a prospective intervention study assessed the effectiveness of bundled interventions. No study solely assessed the effectiveness of interventions to enhance access to influenza vaccination. One moderate quality RCT showed that an influenza pamphlet, with or without a verbalized benefit statement, improved the vaccination rate (RD=0.26; RD=0.39). The other reviewed RCTs showed discordant results, with RDs ranging from -0.15 to 0.03. Although all observational studies significantly improved vaccination rates (RDs ranged from 0.03 to 0.44), the quality of the evidence varied.

CONCLUSIONS

There is a lack of effective interventions to increase the influenza vaccination rate in pregnant women. Based on the existing research, we recommend that clinicians provide influenza pamphlets to pregnant women with a verbalized statement about the benefits of influenza vaccine to newborns. Further high-quality RCTs are needed to develop successful maternal influenza vaccination programs. Increased clarity in reporting the content of interventions would help to improve the comparability and generalizability of the published studies.

Generation of switched memory B cells in response to vaccination in Down syndrome children and their siblings

BACKGROUND

Immunodeficiency is an integral aspect of Down syndrome, as demonstrated by the increased susceptibility to infection of affected. Mortality is still higher than in general population, with respiratory infections among the major causes of death. As more people with Down syndrome are living today than ever before, it is indispensable to develop strategies to prevent and cure the associated disorders. Vaccination is the most successful instrument of preventive medicine. Special seasonal influenza and pneumococcal vaccination strategies have been designed for individuals with risk conditions of all ages. Down syndrome individuals are not included in the high-risk categories.

METHODS

We enrolled in our study 15 children with Down syndrome and their siblings, vaccinated for the first time with seasonal influenza vaccine and receiving a booster dose of a glyco-conjugated pneumococcal vaccine. We compared the immunological features and response to vaccination measuring serum antibody titers and frequency of specific memory B cells.

RESULTS

We confirm that a severe reduction of switched memory B cells is always associated to Down syndrome. After primary vaccination Down syndrome children generate significantly less specific switched memory B cells than their siblings. The response to a booster dose of vaccine is instead comparable in both groups. The production of specific antibodies was equally effective in Down syndrome and controls both after primary and secondary immunization.

CONCLUSIONS

Down syndrome individuals should be considered a high risk group, because of their increased susceptibility to infection and reduced number of switched memory B cells. Tailored vaccination protocols are needed in order to reduce their burden of infections throughout life.

A Socio-Demographic Examination of Adults Responding to Governmental Vaccination Recommendations during the Japanese Rubella Outbreak of 2013

Background

In 2013 a rubella outbreak occurred among Japanese people of working-age which resulted in 14,357 reported cases. The Japanese government subsequently recommended voluntary vaccination or rubella antibody testing for young women (15–49 years of age) who were planning to conceive and for adult men, children, and other persons in potential contact with pregnant women at home. However, the expense and time involved for vaccination, antibody testing and visiting a clinic may represent a major barrier to voluntary compliance among this busy demographic. The aim of the current study was, therefore, to examine potential relationships between the social background of Japanese working-age individuals affected by the 2013 voluntary vaccination campaign.

Methods

A web-based survey of 1,889 Japanese men and women aged 20–49 years was conducted in early 2014. Statistical analyses were used to explore the associations between social background and testing for rubella antibody and / or vaccination uptake during the previous year.

Results

Twenty-four percent of respondents who were planning a pregnancy had been tested for rubella antibody or vaccinated in 2013. However, among those without a current desire for pregnancy, 3% of men and 7% of women, respectively, were tested or vaccinated. Regardless of whether they were planning to conceive, testing for rubella antibodies or vaccination was statistically associated with having acquaintances who had been vaccinated, understanding the government recommendations, and being able to confirm their lack of rubella vaccination history using Maternal and Child Health Handbook records in both men and women.

Conclusion

To help eliminate rubella in Japan, additional initiatives need to target Japanese individuals who cannot envisage a direct benefit from vaccination. The results of this study suggest that disseminating the government recommendation to all potentially affected subpopulations, along with maintaining life-time vaccination records might offer a solution to encourage vaccination uptake among working-age adults in Japan, as elsewhere.

Strategies intended to address vaccine hesitancy: Review of published reviews

When faced with vaccine hesitancy, public health authorities are looking for effective strategies to address this issue. In this paper, the findings of 15 published literature reviews or meta-analysis that have examined the effectiveness of different interventions to reduce vaccine hesitancy and/or to enhance vaccine acceptance are presented and discussed. From the literature, there is no strong evidence to recommend any specific intervention to address vaccine hesitancy/refusal. The reviewed studies included interventions with diverse content and approaches that were implemented in different settings and targeted various populations. Few interventions were directly targeted to vaccine hesitant individuals. Given the paucity of information on effective strategies to address vaccine hesitancy, when interventions are implemented, planning a rigorous evaluation of their impact on vaccine hesitancy/vaccine acceptance will be essential.

Correlates of change in health care worker seasonal influenza vaccination rates among dialysis facilities

We conducted a campaign to increase seasonal influenza vaccination of dialysis health care workers (HCWs) in the District of Columbia, Maryland, Virginia, and West Virginia. Between the 2010-2011 and 2011-2012 influenza seasons we examined the correlates of change. HCW vaccination rates improved significantly (P < .01) from a mean ± standard deviation of 64.5 ± 27.4 to 72.7 ± 23.1. Evidence-based practices were in wide use and although we did not find an association between these and improvement, we did find that lower-performing facilities tended to improve more (P < .01) and there was a positive relationship between patient influenza vaccination rates and improvement in HCW rates (P < .01), with the mean ± standard deviation patient rate of 88.3 ± 7.9 exceeding the HCW rate during the 2011-2012 season (P < .01).

Financial incentives for increasing uptake of HPV vaccinations: a randomized controlled trial

OBJECTIVE

Uptake of human papillomavirus (HPV) vaccinations by 17- to 18-year-old girls in England is below (<35%) target (80%). This trial assesses (a) the impact of financial incentives on uptake and completion of an HPV vaccination program, and (b) whether impacts are moderated by participants' deprivation level. It also assesses the impact of incentives on decision quality to get vaccinated, as measured by attitudes toward the vaccination and knowledge of its consequences.

METHOD

One thousand 16- to 18-year-old girls were invited to participate in an HPV vaccination program: 500 previously uninvited, and 500 unresponsive to previous invitations. Girls randomly received either a standard invitation letter or a letter including the offer of vouchers worth £ 45 (€ 56; $73) for undergoing 3 vaccinations. Girls attending their first vaccination appointment completed a questionnaire assessing decision quality to be vaccinated. Outcomes were uptake of the first and third vaccinations and decision quality.

RESULTS

The intervention increased uptake of the first (first-time invitees: 28.4% vs. 19.6%, odds ratio [OR] = 1.63, 95% confidence interval [CI; 1.08, 2.47]; previous nonattenders: 23.6% vs. 10.4%, OR = 2.65, 95% CI [1.61, 4.38]) and third (first-time invitees: 22.4% vs. 12%, OR = 2.15, 95% CI [1.32, 3.50]; previous nonattenders: 12.4% vs. 3%, OR = 4.28, 95% CI [1.92, 9.55]) vaccinations. Impacts were not moderated by deprivation level. Decision quality was unaffected by the intervention.

CONCLUSIONS

Although the intervention increased completion of HPV vaccinations, uptake remained lower than the national target, which, in addition to cost effectiveness and acceptability issues, necessitates consideration of other ways of achieving it.

A review of acute care interventions to improve inpatient pneumococcal vaccination

OBJECTIVE

To provide a narrative review of the impact of provider-based, organizational strategies in acute care settings to improve pneumococcal vaccination rates among patients over 65, and 2-64 years with high risk medical conditions.

METHODS

A search was conducted using MEDLINE, Scopus, CINAHL and Web of Science databases for hospital-based, inpatient studies which evaluated strategies to improve pneumococcal vaccination rates. Studies published in English from 1983 to 2013 were included. Data abstracted was analyzed descriptively.

RESULTS

A total of 35 studies were included; 15 evaluated physician reminders (e.g. chart or paper reminders, pre-printed orders (PPOs), computerized reminders, checklists) and 21 standing orders programs (SOPs). The most common study design was pre/post, and only 7 studies had a control group. Overall, 32 studies showed improvements in the rate of pneumococcal vaccination following intervention (19 statistically significant), with reminders showing 29-74% immunization rate, PPCO 5-42%, and SOPs 3.4-78%.

CONCLUSION

Hospital-based interventions improve pneumococcal vaccination in older adults and younger individuals at risk. Although this review found that more success was observed with SOPs the impact on immunization rates in eligible patients varied significantly. Thus, high quality, randomized-controlled studies are required to determine the effect of each type of institutional immunization strategy.

Cost-effectiveness of programs to eliminate disparities in elderly vaccination rates in the United States

BACKGROUND

There are disparities in influenza and pneumococcal vaccination rates among elderly minority groups and little guidance as to which intervention or combination of interventions to eliminate these disparities is likely to be most cost-effective. Here, we evaluate the cost-effectiveness of four hypothetical vaccination programs designed to eliminate disparities in elderly vaccination rates and differing in the number of interventions.

METHODS

We developed a Markov model in which we assumed a healthcare system perspective, 10-year vaccination program and lifetime time horizon. The cohort was the combined African-American and Hispanic 65 year-old birth cohort in the United States in 2009. We evaluated five different vaccination strategies: no vaccination program and four vaccination programs that varied from "low intensity" to "very high intensity" based on the number of interventions deployed in each program, their cumulative cost and their cumulative impact on elderly minority influenza and pneumococcal vaccination rates.

RESULTS

The very high intensity vaccination program ($24,479/quality-adjusted life year; QALY) was preferred at willingness-to-pay-thresholds of $50,000 and $100,000/QALY and prevented 37,178 influenza cases, 342 influenza deaths, 1,158 invasive pneumococcal disease (IPD) cases and 174 IPD deaths over the birth cohort's lifetime. In one-way sensitivity analyses, the very high intensity program only became cost-prohibitive (>$100,000/QALY) at less likely values for the influenza vaccination rates achieved in year 10 of the high intensity (>73.5%) or very high intensity (<76.8%) vaccination programs.

CONCLUSIONS

A practice-based vaccination program designed to eliminate disparities in elderly minority vaccination rates and including four interventions would be cost-effective.

Interventions to increase influenza vaccination rates of those 60 years and older in the community

BACKGROUND

The effectiveness of interventions to increase the uptake of influenza vaccination in people aged 60 and older is uncertain.

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 (2014, Issue 5), MEDLINE (January 1950 to May week 3 2014), EMBASE (1980 to June 2014), AgeLine (1978 to 4 June 2014), ERIC (1965 to June 2014) and CINAHL (1982 to June 2014).

SELECTION CRITERIA

Randomised controlled trials (RCTs) of interventions to increase influenza vaccination uptake in people aged 60 and older.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study quality and extracted influenza vaccine uptake data.

MAIN RESULTS

This update identified 13 new RCTs; the review now includes a total of 57 RCTs with 896,531 participants. The trials included community-dwelling seniors in high-income countries. Heterogeneity limited meta-analysis. The percentage of trials with low risk of bias for each domain was as follows: randomisation (33%); allocation concealment (11%); blinding (44%); missing data (49%) and selective reporting (100%). Increasing community demand (32 trials, 10 strategies)The interventions with a statistically significant result were: three trials (n = 64,200) of letter plus leaflet/postcard compared to letter (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.07 to 1.15); two trials (n = 614) of nurses/pharmacists educating plus vaccinating patients (OR 3.29, 95% CI 1.91 to 5.66); single trials of a phone call from a senior (n = 193) (OR 3.33, 95% CI 1.79 to 6.22), a telephone invitation versus clinic drop-in (n = 243) (OR 2.72, 95% CI 1.55 to 4.76), a free groceries lottery (n = 291) (OR 1.04, 95% CI 0.62 to 1.76) and nurses educating and vaccinating patients (n = 485) (OR 152.95, 95% CI 9.39 to 2490.67).We did not pool the following trials due to considerable heterogeneity: postcard/letter/pamphlets (16 trials, n = 592,165); tailored communications (16 trials, n = 388,164); customised letter/phone-call (four trials, n = 82,465) and client-based appraisals (three trials, n = 4016), although several trials showed the interventions were effective. Enhancing vaccination access (10 trials, six strategies)The interventions with a statistically significant result were: two trials (n = 2112) of home visits compared to clinic invitation (OR 1.30, 95% CI 1.05 to 1.61); two trials (n = 2251) of free vaccine (OR 2.36, 95% CI 1.98 to 2.82) and one trial (n = 321) of patient group visits (OR 24.85, 95% CI 1.45 to 425.32). One trial (n = 350) of a home visit plus vaccine encouragement compared to a home visit plus safety advice was non-significant.We did not pool the following trials due to considerable heterogeneity: nurse home visits (two trials, n = 2069) and free vaccine compared to no intervention (two trials, n = 2250). Provider- or system-based interventions (17 trials, 11 strategies)The interventions with a statistically significant result were: two trials (n = 2815) of paying physicians (OR 2.22, 95% CI 1.77 to 2.77); one trial (n = 316) of reminding physicians about all their patients (OR 2.47, 95% CI 1.53 to 3.99); one trial (n = 8376) of posters plus postcards (OR 2.03, 95% CI 1.86 to 2.22); one trial (n = 1360) of chart review/feedback (OR 3.43, 95% CI 2.37 to 4.97) and one trial (n = 27,580) of educational outreach/feedback (OR 0.77, 95% CI 0.72 to 0.81).Trials of posters plus postcards versus posters (n = 5753), academic detailing (n = 1400) and increasing staff vaccination rates (n = 26,432) were non-significant.We did not pool the following trials due to considerable heterogeneity: reminding physicians (four trials, n = 202,264) and practice facilitators (three trials, n = 2183), although several trials showed the interventions were effective. Interventions at the societal level We identified no RCTs of interventions at the societal level.

AUTHORS' CONCLUSIONS

There are interventions that are effective for increasing community demand for vaccination, enhancing access and improving provider/system response. Heterogeneity limited pooling of trials.

[Improvement of pneumococcal immunization coverage in older patients]

PURPOSE

To study pneumococcal immunization coverage in older patients in hospital, and the impact of two actions aiming at improving this coverage.

METHODS

We reported a prospective and descriptive study conducted from November 2009 to August 2010, including all new patients ≥75 years old received in a geriatric short-stay department and residing in Val-de-Marne, France. This study was performed in three successive three-month periods, to assess the vaccination coverage in the months following hospital release. Period I was the reference; Period II included an awareness campaign of general practitioners relying on the hospitalization discharge report, containing an indication for the vaccination; Period III consisted in a systematic proposal of vaccination by the geriatric hospital department.

RESULTS

Indication for pneumococcal vaccination has been given to 139 patients (61.2%) in 227 processed questionnaires. The main indication was heart failure for 105 patients (75.5%). Twenty-four patients were already vaccinated (17.2%). No vaccination was reported in the three months following period I in 33 included patients. The awareness campaign targeting regular doctors resulted in only one vaccination out of 37 patients. Immunization coverage in the department had reached 84.5% of inoculation (38 of 45 patients).

CONCLUSION

Pneumococcal vaccination is often prescribed in elderly patients but generally not executed. The awareness campaign did not result in a big enough immunization coverage improvement, compared to a codified proposal of vaccination during hospital stay.

National and state-specific estimates of place of influenza vaccination among adult populations - United States, 2011-12 influenza season

BACKGROUND

Annual influenza vaccination has been recommended for all persons ≥6 months since the 2010-11 season. New partnerships between public health agencies and medical and nonmedical vaccination providers have increased the number of vaccination providers and locations where vaccination services are delivered.

METHODS

Data from the 2011-12 Behavioral Risk Factor Surveillance System (BRFSS) were analyzed. Point estimates of place of vaccination and 95% confidence intervals were calculated. Multivariable logistic regression and predictive marginal modeling were conducted to identify factors associated with vaccination settings.

RESULTS

Among adults vaccinated during the 2011-12 influenza season, a doctor's office was the most common place (38.4%) for receipt of influenza vaccination, with stores (e.g., supermarkets or drug stores) (20.1%) the next common, and workplaces (17.6%) the third common. Overall, reported vaccination in nonmedical settings by state ranged from 32.2% in California to 60.4% in Nevada, with a median of 45.8%. Characteristics significantly associated with an increased likelihood of receipt of vaccination in nonmedical settings were higher education, not having certain identified high-risk conditions, not having had a routine checkup in the previous 12 months, and not having a primary doctor for health care. Being a member of a racial/ethnic minority group, unemployed or not in the work force were significantly associated with a decreased likelihood of receipt of vaccination in nonmedical settings.

CONCLUSION

Doctor's offices were the most common medical setting for adult influenza vaccination; workplaces and stores were important nonmedical settings. Increasing access to vaccination services in medical and nonmedical settings should be considered as important strategies for improving vaccination coverage. These results also can help guide development of strategies for achieving Healthy People 2020 objectives for influenza vaccination of adult populations.

Interventions to improve safe and effective medicines use by consumers: an overview of systematic reviews

BACKGROUND

Many systematic reviews exist on interventions to improve safe and effective medicines use by consumers, but research is distributed across diseases, populations and settings. The scope and focus of such reviews also vary widely, creating challenges for decision-makers seeking to inform decisions by using the evidence on consumers' medicines use.This is an update of a 2011 overview of systematic reviews, which synthesises the evidence, irrespective of disease, medicine type, population or setting, on the effectiveness of interventions to improve consumers' medicines use.

OBJECTIVES

To assess the effects of interventions which target healthcare consumers to promote safe and effective medicines use, by synthesising review-level evidence.

METHODS

SEARCH METHODS

We included systematic reviews published on the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects. We identified relevant reviews by handsearching databases from their start dates to March 2012.

SELECTION CRITERIA

We screened and ranked reviews based on relevance to consumers' medicines use, using criteria developed for this overview.

DATA COLLECTION AND ANALYSIS

We used standardised forms to extract data, and assessed reviews for methodological quality using the AMSTAR tool. We used standardised language to summarise results within and across reviews; and gave bottom-line statements about intervention effectiveness. Two review authors screened and selected reviews, and extracted and analysed data. We used a taxonomy of interventions to categorise reviews and guide syntheses.

MAIN RESULTS

We included 75 systematic reviews of varied methodological quality. Reviews assessed interventions with diverse aims including support for behaviour change, risk minimisation and skills acquisition. No reviews aimed to promote systems-level consumer participation in medicines-related activities. Medicines adherence was the most frequently-reported outcome, but others such as knowledge, clinical and service-use outcomes were also reported. Adverse events were less commonly identified, while those associated with the interventions themselves, or costs, were rarely reported.Looking across reviews, for most outcomes, medicines self-monitoring and self-management programmes appear generally effective to improve medicines use, adherence, adverse events and clinical outcomes; and to reduce mortality in people self-managing antithrombotic therapy. However, some participants were unable to complete these interventions, suggesting they may not be suitable for everyone.Other promising interventions to improve adherence and other key medicines-use outcomes, which require further investigation to be more certain of their effects, include:· simplified dosing regimens: with positive effects on adherence;· interventions involving pharmacists in medicines management, such as medicines reviews (with positive effects on adherence and use, medicines problems and clinical outcomes) and pharmaceutical care services (consultation between pharmacist and patient to resolve medicines problems, develop a care plan and provide follow-up; with positive effects on adherence and knowledge).Several other strategies showed some positive effects, particularly relating to adherence, and other outcomes, but their effects were less consistent overall and so need further study. These included:· delayed antibiotic prescriptions: effective to decrease antibiotic use but with mixed effects on clinical outcomes, adverse effects and satisfaction;· practical strategies like reminders, cues and/or organisers, reminder packaging and material incentives: with positive, although somewhat mixed effects on adherence;· education delivered with self-management skills training, counselling, support, training or enhanced follow-up; information and counselling delivered together; or education/information as part of pharmacist-delivered packages of care: with positive effects on adherence, medicines use, clinical outcomes and knowledge, but with mixed effects in some studies;· financial incentives: with positive, but mixed, effects on adherence.Several strategies also showed promise in promoting immunisation uptake, but require further study to be more certain of their effects. These included organisational interventions; reminders and recall; financial incentives; home visits; free vaccination; lay health worker interventions; and facilitators working with physicians to promote immunisation uptake. Education and/or information strategies also showed some positive but even less consistent effects on immunisation uptake, and need further assessment of effectiveness and investigation of heterogeneity.There are many different potential pathways through which consumers' use of medicines could be targeted to improve outcomes, and simple interventions may be as effective as complex strategies. However, no single intervention assessed was effective to improve all medicines-use outcomes across all diseases, medicines, populations or settings.Even where interventions showed promise, the assembled evidence often only provided part of the picture: for example, simplified dosing regimens seem effective for improving adherence, but there is not yet sufficient information to identify an optimal regimen.In some instances interventions appear ineffective: for example, the evidence suggests that directly observed therapy may be generally ineffective for improving treatment completion, adherence or clinical outcomes.In other cases, interventions may have variable effects across outcomes. As an example, strategies providing information or education as single interventions appear ineffective to improve medicines adherence or clinical outcomes, but may be effective to improve knowledge; an important outcome for promoting consumers' informed medicines choices.Despite a doubling in the number of reviews included in this updated overview, uncertainty still exists about the effectiveness of many interventions, and the evidence on what works remains sparse for several populations, including children and young people, carers, and people with multimorbidity.

AUTHORS' CONCLUSIONS

This overview presents evidence from 75 reviews that have synthesised trials and other studies evaluating the effects of interventions to improve consumers' medicines use.Systematically assembling the evidence across reviews allows identification of effective or promising interventions to improve consumers' medicines use, as well as those for which the evidence indicates ineffectiveness or uncertainty.Decision makers faced with implementing interventions to improve consumers' medicines use can use this overview to inform decisions about which interventions may be most promising to improve particular outcomes. The intervention taxonomy may also assist people to consider the strategies available in relation to specific purposes, for example, gaining skills or being involved in decision making. Researchers and funders can use this overview to identify where more research is needed and assess its priority. The limitations of the available literature due to the lack of evidence for important outcomes and important populations, such as people with multimorbidity, should also be considered in practice and policy decisions.

Healthcare worker compliance with seasonal and pandemic influenza vaccination

Healthcare workers (HCWs) can be an important source of transmission of influenza to patients and family members, and their well-being is fundamental to the maintenance of healthcare services during influenza outbreaks and pandemics. Unfortunately, studies have shown consistently low levels of compliance with influenza vaccination among HCWs, a finding that became particularly pronounced during recent pandemic vaccination campaigns. Among the variables associated with vaccine acceptance in this group are demographic factors, fears and concerns over vaccine safety and efficacy, perceptions of risk and personal vulnerability, past vaccination behaviours and experience with influenza illness, as well as certain situational and organisational constructs. We report the findings of a review of the literature on these factors and highlight some important challenges in interpreting the data. In particular, we point out the need for longitudinal study designs, as well as focused research and interventions that are adapted to the most resistant HCW groups. Multi-pronged strategies are an important step forward in ensuring that future influenza vaccination campaigns, whether directed at seasonal or pandemic strains, will be successful in ensuring broad coverage among HCWs.

Factors associated with influenza vaccination decisions among patients with mental illness

OBJECTIVE

To determine influenza (flu) vaccination status among the mentally ill population and identify factors associated with vaccination status.

METHOD

A non-interventional, cross-sectional study was conducted. A self-administered survey to investigate the vaccination status and perceptions related to flu vaccine was administered between October 2011-January 2012 in an outpatient psychiatry clinic that served the indigent, severely mentally ill population of Alabama. All statistical analyses were based upon a significance level of 0.05.

RESULTS

Of the 736 patients invited, 302 participated (41%). Only 28.4% were vaccinated in 2010-2011 and 24.2% had been vaccinated at the time of the survey for 2011-2012. Respondents who had private health insurance, received a recommendation from healthcare providers, and who perceived a greater degree of vaccine effectiveness were more likely to obtain flu vaccination while respondents who had education beyond high school and were more in agreement that they can get the flu from the vaccine were less likely to obtain flu vaccination. All of the above factors accounted for 26.7% of vaccination decisions.

CONCLUSIONS

The flu vaccination rate among this study's population was lower than the general population. Interventions targeting the above factors should help increase vaccination rates among the mentally ill population.

Pharmacy-based Immunization in Rural Communities Strategy (PhICS): A community cluster-randomized trial

BACKGROUND

Influenza is a major cause of morbidity and mortality in Canada, with up to 7000 influenza-related deaths occurring every year. The elderly and individuals with chronic diseases are at increased risk for influenza-related morbidity and mortality.

METHODS

We conducted a 2-year, community cluster-randomized trial targeting elderly people and at-risk groups to assess the effectiveness of pharmacy-based influenza vaccination clinics on influenza vaccination rates. Small rural communities in interior and northern British Columbia were randomly allocated to the intervention or control. In the intervention communities, pharmacy-based influenza vaccination clinics were held and were promoted to eligible patients using personalized invitations from the pharmacists, invitations distributed opportunistically by a pharmacist to eligible patients presenting to pharmacies during the flu season and community-wide promotion using posters and the local media. The main outcome measure was a difference in the mean influenza vaccination rates. The immunization rates were calculated using the number of immunizations given in each community divided by the population size estimated from the census data.

RESULTS

Baseline influenza immunization rates in the population ≥65 years of age were the same in the control (n = 10, mean 85.6% [SD 16.6]) and intervention (n = 14, mean 83.8% [SD 16.3]) communities in 2009 (p = 0.79). In 2010, the mean influenza immunization rate was 56.9% (SD 28.0) in the control communities (n = 15) and 80.1% (SD 18.4) in the intervention communities (n = 14) (p = 0.01) for those ≥65 years of age. However, in 2010, for those 2 to 64 years with chronic medical conditions, the immunization rates were lower in the intervention communities (mean 16.3% [SD 7.1]) compared with the control communities (mean 21.2% [SD 5.8]) (p = 0.04).

CONCLUSION

Clinics were feasible and well attended and they resulted in increased vaccination rates for elderly residents. In contrast, vaccination rates in the younger population with comorbidities remained low and unchanged.

Influenza A (H1N1) 2009 monovalent and seasonal influenza vaccination among adults 25 to 64 years of age with high-risk conditions--United States, 2010

BACKGROUND

Seasonal influenza vaccination has been routinely recommended for adults with high-risk conditions. The Advisory Committee on Immunization Practices recommended that persons 25 to 64 years of age with high-risk conditions be one of the initial target groups to receive H1N1 vaccination during the 2009-2010 season.

METHODS

We used data from the 2009-2010 Behavioral Risk Factor Surveillance System survey. Vaccination levels of H1N1 and seasonal influenza vaccination among respondents 25 to 64 years with high-risk conditions were assessed. Multivariable logistic regression models were performed to identify factors independently associated with vaccination.

RESULTS

Overall, 24.8% of adults 25 to 64 years of age were identified to have high-risk conditions. Among adults 25 to 64 years of age with high-risk conditions, H1N1 and seasonal vaccination coverage were 26.3% and 47.6%, respectively. Characteristics independently associated with an increased likelihood of H1N1 vaccination were as follows: higher age; Hispanic race/ethnicity; medical insurance; ability to see a doctor if needed; having a primary doctor; a routine checkup in the previous year; not being a current smoker; and having high-risk conditions other than asthma, diabetes, and heart disease. Characteristics independently associated with seasonal influenza vaccination were similar compared with factors associated with H1N1 vaccination.

CONCLUSION

Immunization programs should work with provider organizations to review efforts made to reach adults with high-risk conditions during the recent pandemic and assess how and where they can increase vaccination coverage during future pandemics.

Notification about influenza vaccination in Belgium: a descriptive study of how people want to be informed

BACKGROUND

Influenza causes a substantial socioeconomic burden. In Belgium, only 54% of the target group receives an annual vaccination. Patient reminder/recall systems are effective in improving vaccination rates in primary care, but little is known about patients' preferences on notification of influenza vaccination.

AIMS

To evaluate whether general practice patients wish to be notified of the possibility of receiving influenza immunisation, and how.

METHODS

In January 2008, 750 questionnaires were handed out to all consecutive patients aged >18 years in three Belgian general practices. Main outcome measures were the percentage wanting to be notified, demographic and medical factors influencing the information needs of the patients and the specific way in which patients wanted to be notified.

RESULTS

About 80% of respondents wanted to be notified of the possibility of influenza vaccination. Logistic regression analysis showed that those who had previously been vaccinated particularly wished to be notified, both in the total population (OR 4.45; 95% CI 2.87 to 6.90; p<0.0001) and in the subgroup of high-risk individuals (OR 9.05; 95% CI 4.47 to 18.33; p<0.0001). More than 85% of the participants wanted to be informed by their family physician, mostly during a consultation regardless of the reason for the encounter. The second most preferred option was a letter sent by the family physician enclosing a prescription.

CONCLUSIONS

The majority of general practice patients want to be notified of the possibility of influenza vaccination. More than 85% of participants who wanted to be notified preferred to receive this information from their family physician, mostly by personal communication during a regular visit. However, since a large minority preferred to be addressed more proactively (letter, telephone call, e-mail), GPs should be encouraged to combine an opportunistic approach with a proactive one.

Computer-generated reminders delivered on paper to healthcare professionals; effects on professional practice and health care outcomes

BACKGROUND

Clinical practice does not always reflect best practice and evidence, partly because of unconscious acts of omission, information overload, or inaccessible information. Reminders may help clinicians overcome these problems by prompting the doctor to recall information that they already know or would be expected to know and by providing information or guidance in a more accessible and relevant format, at a particularly appropriate time.

OBJECTIVES

To evaluate the effects of reminders automatically generated through a computerized system and delivered on paper to healthcare professionals on processes of care (related to healthcare professionals' practice) and outcomes of care (related to patients' health condition).

SEARCH METHODS

For this update the EPOC Trials Search Co-ordinator searched the following databases between June 11-19, 2012: The Cochrane Central Register of Controlled Trials (CENTRAL) and Cochrane Library (Economics, Methods, and Health Technology Assessment sections), Issue 6, 2012; MEDLINE, OVID (1946- ), Daily Update, and In-process; EMBASE, Ovid (1947- ); CINAHL, EbscoHost (1980- ); EPOC Specialised Register, Reference Manager, and INSPEC, Engineering Village. The authors reviewed reference lists of related reviews and studies. 

SELECTION CRITERIA

We included individual or cluster-randomized controlled trials (RCTs) and non-randomized controlled trials (NRCTs) that evaluated the impact of computer-generated reminders delivered on paper to healthcare professionals on processes and/or outcomes of care.

DATA COLLECTION AND ANALYSIS

Review authors working in pairs independently screened studies for eligibility and abstracted data. We contacted authors to obtain important missing information for studies that were published within the last 10 years. For each study, we extracted the primary outcome when it was defined or calculated the median effect size across all reported outcomes. We then calculated the median absolute improvement and interquartile range (IQR) in process adherence across included studies using the primary outcome or median outcome as representative outcome.

MAIN RESULTS

In the 32 included studies, computer-generated reminders delivered on paper to healthcare professionals achieved moderate improvement in professional practices, with a median improvement of processes of care of 7.0% (IQR: 3.9% to 16.4%). Implementing reminders alone improved care by 11.2% (IQR 6.5% to 19.6%) compared with usual care, while implementing reminders in addition to another intervention improved care by 4.0% only (IQR 3.0% to 6.0%) compared with the other intervention. The quality of evidence for these comparisons was rated as moderate according to the GRADE approach. Two reminder features were associated with larger effect sizes: providing space on the reminder for provider to enter a response (median 13.7% versus 4.3% for no response, P value = 0.01) and providing an explanation of the content or advice on the reminder (median 12.0% versus 4.2% for no explanation, P value = 0.02). Median improvement in processes of care also differed according to the behaviour the reminder targeted: for instance, reminders to vaccinate improved processes of care by 13.1% (IQR 12.2% to 20.7%) compared with other targeted behaviours. In the only study that had sufficient power to detect a clinically significant effect on outcomes of care, reminders were not associated with significant improvements.

AUTHORS' CONCLUSIONS

There is moderate quality evidence that computer-generated reminders delivered on paper to healthcare professionals achieve moderate improvement in process of care. Two characteristics emerged as significant predictors of improvement: providing space on the reminder for a response from the clinician and providing an explanation of the reminder's content or advice. The heterogeneity of the reminder interventions included in this review also suggests that reminders can improve care in various settings under various conditions.

Interventions to improve influenza and pneumococcal vaccination rates among community-dwelling adults: a systematic review and meta-analysis

PURPOSE

Influenza and pneumococcal vaccination rates remain below national targets. We systematically reviewed the effectiveness of quality improvement interventions for increasing the rates of influenza and pneumococcal vaccinations among community-dwelling adults.

METHODS

We included randomized and nonrandomized studies with a concurrent control group. We estimated pooled odds ratios using random effects models, and used the Downs and Black tool to assess the quality of included studies.

RESULTS

Most studies involved elderly primary care patients. Interventions were associated with improvements in the rates of any vaccination (111 comparisons in 77 studies, pooled odds ratio [OR] = 1.61, 95% CI, 1.49-1.75), and influenza (93 comparisons, 65 studies, OR = 1.46, 95% CI, 1.35-1.57) and pneumococcal (58 comparisons, 35 studies, OR = 2.01, 95% CI, 1.72-2.3) vaccinations. Interventions that appeared effective were patient financial incentives (influenza only), audit and feedback (influenza only), clinician reminders, clinician financial incentives (influenza only), team change, patient outreach, delivery site changes (influenza only), clinician education (pneumococcus only), and case management (pneumococcus only). Patient outreach was more effective if personal contact was involved. Team changes were more effective where nurses administered influenza vaccinations independently. Heterogeneity in some pooled odds ratios was high, however, and funnel plots showed signs of potential publication bias. Study quality varied but was not associated with outcomes.

CONCLUSIONS

Quality improvement interventions, especially those that assign vaccination responsibilities to nonphysician personnel or that activate patients through personal contact, can modestly improve vaccination rates in community-dwelling adults. To meet national policy targets, more-potent interventions should be developed and evaluated.

New opportunity for vaccinating older people: well-child clinic visits

BACKGROUND

Streptococcus pneumoniae causes considerable morbidity and mortality in the elderly. As aging of the population is making the health of the elderly a universal priority, preventive measures, such as vaccination, will become increasingly important.

METHODS

We designed a prospective interventional study to determine whether recommendations to vaccinate grandparents of children attending well-child clinics would increase the pneumococcal vaccination rate in the elderly. Children younger than 5 years of age, attending a university well-child clinic from 1 May to 31 September 2008 who had grandparents over 65 years of age were eligible. A survey including the questions about the demographic characteristics of children, their parents and grandparents over 65 was carried out by face-to-face interview with the parents. High-risk medical conditions and vaccination history of grandparents was also noted and the benefits and necessity of pneumococcal vaccination (23vPPV) for the elderly was emphasized. Four months later these families were contacted to determine whether this intervention had increased the pneumococcal vaccination rates of the elderly.

RESULTS

Information was obtained from 938 grandparents of 545 children. Before the interview, among all grandparents, only 0.9% were vaccinated with 23vPPV. Four months after this intervention, immunization coverage increased to 19.1%. The sex of the grandchild (OR: 1.99) and previous hepatitis B or influenza immunization of the grandparents (OR: 2.73) were the significant parameters accounting for higher immunization rates.

CONCLUSION

Reminding elderly grandparents about vaccines in well-child clinics could be an opportunity in this field.
