Abstract
Although immunization can dramatically curb the mortality and morbidity associated with vaccine-preventable diseases, vaccination uptake remains suboptimal in many areas of the world. Here, in this meta-analysis, we analysed the results from 88 eligible randomized controlled trials testing interventions to increase vaccination uptake with 1,628,768 participants from 17 countries with variable development levels (for example, Human Development Index ranging from 0.485 to 0.955). We estimated the efficacy of seven intervention strategies including increasing access to vaccination, sending vaccination reminders, providing incentives, supplying information, correcting misinformation, promoting both active and passive motivation and teaching behavioural skills. We showed that the odds of vaccination were 1.5 (95% confidence interval, 1.27 to 1.77) times higher for intervention than control conditions. Among the intervention strategies, using incentives and increasing access were most promising in improving vaccination uptake, with the access strategy being particularly effective in countries with lower incomes and less access to healthcare.

Timeliness of Childhood Vaccinations Following Strengthening of the Second Year of Life (2YL) Immunization Platform and Introduction of Catch-Up Vaccination Policy in Ghana. Vaccines (Basel) 2024; 12:716. [PMID: 39066354 PMCID: PMC11281534 DOI: 10.3390/vaccines12070716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 06/20/2024] [Accepted: 06/23/2024] [Indexed: 07/28/2024] Open
Abstract
Strengthening routine immunization systems to successfully deliver childhood vaccines during the second year of life (2YL) is critical for vaccine-preventable disease control. In Ghana, the 18-month visit provides opportunities to deliver the second dose of the measles-rubella vaccine (MR2) and for healthcare workers to assess for and provide children with any missed vaccine doses. In 2016, the Ghana Health Service (GHS) revised its national immunization policies to include guidelines for catch-up vaccinations. This study assessed the change in the timely receipt of vaccinations per Ghana's Expanded Program on Immunizations (EPI) schedule, an important indicator of service quality, following the introduction of the catch-up policy and implementation of a multifaceted intervention package. Vaccination coverage was assessed from household surveys conducted in the Greater Accra, Northern, and Volta regions for 392 and 931 children aged 24-35 months with documented immunization history in 2016 and 2020, respectively. Age at receipt of childhood vaccines was compared to the recommended age, as per the EPI schedule. Cumulative days under-vaccinated during the first 24 months of life for each recommended dose were assessed. Multivariable Cox regression was used to assess the associations between child and caregiver characteristics and time to MR2 vaccination. From 2016 to 2020, the proportion of children receiving all recommended doses on schedule generally improved, the duration of under-vaccination was shortened for most doses, and higher coverage rates were achieved at earlier ages for the MR series. More timely infant doses and caregiver awareness of the 2YL visit were positively associated with MR2 vaccination. Fostering a well-supported cadre of vaccinators, building community demand for 2YL vaccination, sustaining service utilization through strengthened defaulter tracking and caregiver-reminder systems, and creating a favorable policy environment that promotes vaccination over the life course are critical to improving the timeliness of childhood vaccinations.

Effective interventions for improving routine childhood immunisation in low and middle-income countries: a systematic review of systematic reviews. BMJ Open 2024; 14:e074370. [PMID: 38365291 PMCID: PMC10875475 DOI: 10.1136/bmjopen-2023-074370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Accepted: 01/30/2024] [Indexed: 02/18/2024] Open
Abstract
OBJECTIVE An umbrella review providing a comprehensive synthesis of the interventions that are effective in providing routine immunisation outcomes for children in low and middle-income countries (L&MICs). DESIGN A systematic review of systematic reviews, or an umbrella review. DATA SOURCES We comprehensively searched 11 academic databases and 23 grey literature sources. The search was adopted from an evidence gap map on routine child immunisation sector in L&MICs, which was done on 5 May 2020. We updated the search in October 2021. ELIGIBILITY CRITERIA We included systematic reviews assessing the effectiveness of any intervention on routine childhood immunisation outcomes in L&MICs. DATA EXTRACTION AND SYNTHESIS Search results were screened by two reviewers independently applying predefined inclusion and exclusion criteria. Data were extracted by two researchers independently. The Specialist Unit for Review Evidence checklist was used to assess review quality. A mixed-methods synthesis was employed focusing on meta-analytical and narrative elements to accommodate both the quantitative and qualitative information available from the included reviews. RESULTS 62 systematic reviews are included in this umbrella review. We find caregiver-oriented interventions have large positive and statistically significant effects, especially those focusing on short-term sensitisation and education campaigns as well as written messages to caregivers. For health system-oriented interventions the evidence base is thin and derived from narrative synthesis suggesting positive effects for home visits, mixed effects for pay-for-performance schemes and inconclusive effects for contracting out services to non-governmental providers. For all other interventions under this category, the evidence is either limited or not available. For community-oriented interventions, a recent high-quality mixed-methods review suggests positive but small effects. Overall, the evidence base is highly heterogenous in terms of scope, intervention types and outcomes. CONCLUSION Interventions oriented towards caregivers and communities are effective in improving routine child immunisation outcomes. The evidence base on health system-oriented interventions is scant not allowing us to reach firm conclusions, except for home visits. Large evidence gaps exist and need to be addressed. For example, more high-quality evidence is needed for specific caregiver-oriented interventions (eg, monetary incentives) as well as health system-oriented (eg, health workers and data systems) and community-oriented interventions. We also need to better understand complementarity of different intervention types.

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

Abstract
Global Human papillomavirus (HPV) vaccination rates remain low despite available WHO-approved vaccines. Digital interventions for promoting vaccination uptake offer a scalable and accessible solution to this issue. Here we report a systematic review and meta-analysis examining the efficacy of digital interventions, comparing educational and reminder approaches, for promoting HPV vaccination uptake (HVU). This study also identifies factors influencing the effectiveness of these interventions. We searched PubMed, PsycInfo, Web of Science, and the Cochrane Library from each database's inception to January 2023. Three raters independently evaluate the studies using a systematic and blinded method for resolving disagreements. From 1929 references, 34 unique studies (281,280 unique participants) have sufficient data. Client reminder (OR, 1.41; 95% CI, 1.23-1.63; P < 0.001), provider reminder (OR, 1.39; 95% CI, 1.11-1.75; P = 0.005), provider education (OR, 1.18; 95% CI, 1.05-1.34; P = 0.007), and client education plus reminder interventions (OR, 1.29; 95% CI, 1.04-1.59; P = 0.007) increase HVU, whereas client education interventions do not (OR, 1.08; 95% CI, 0.92-1.28; P = 0.35). Digital intervention effectiveness varies based on participants' gender and the digital platform used. Interventions targeting male or mixed-gender participants demonstrate greater benefit, and reminder platforms (SMS, preference reminders, or electronic health record alerts) are more effective in increasing HVU. Digital interventions, particularly client and provider reminders, along with provider education, prove significantly more effective than client education alone. Incorporating digital interventions into healthcare systems can effectively promote HPV vaccination uptake. Reminder interventions should be prioritized for promoting HVU.

Abstract
Malaysian healthcare institutions still use ineffective paper-based vaccination systems to manage childhood immunization schedules. This may lead to missed appointments, incomplete vaccinations, and outbreaks of preventable diseases among infants. To address this issue, a text messaging vaccination reminder and recall system named Virtual Health Connect (VHC) was studied. VHC simplifies and accelerates immunization administration for nurses, which may result in improving the completion and timeliness of immunizations among infants. Considering the limited research on the acceptance of these systems in the healthcare sector, we examined the factors influencing nurses' attitudes and intentions to use VHC using the extended technology acceptance model (TAM). The novelty of the conceptual model is the incorporation of new predictors of attitude, namely, perceived compatibility and perceived privacy and security issues. We conducted a survey among 121 nurses in Malaysian government hospitals and clinics to test the model. We analyzed the collected data using partial least squares structural equation modeling (PLS-SEM) to examine the significant factors influencing nurses' attitudes and intentions to use VHC. Moreover, we applied an artificial neural network (ANN) to determine the most significant factors of acceptance with higher accuracy. Therefore, we could offer more accurate insights to decision-makers in the healthcare sector for the advancement of health services. Our results highlighted that the compatibility of VHC with the current work setting of nurses developed their positive perspectives on the system. Moreover, the nurses felt optimistic about the system when they considered it useful and easy to use in the workplace. Finally, their attitude toward using VHC played a pivotal role in increasing their intention to use it. Based on the ANN models, we also found that perceived compatibility was the most significant factor influencing nurses' attitudes towards using VHC, followed by perceived ease of use and perceived usefulness.

A Behavioural-Theory-Based Qualitative Study of the Beliefs and Perceptions of Marginalised Populations towards Community Volunteering to Increase Measles Immunisation Coverage in Sabah, Malaysia. Vaccines (Basel) 2023; 11:1056. [PMID: 37376445 DOI: 10.3390/vaccines11061056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 05/16/2023] [Accepted: 05/31/2023] [Indexed: 06/29/2023] Open
Abstract
The development of the measles-containing vaccine (MCV) has rendered measles a largely preventable disease. In the state of Sabah in Malaysia, a complete course of measles immunisation for infants involves vaccinations at the ages of six, nine, and twelve months. However, it is difficult for marginalised populations to receive a complete course of measles immunisation. This present study used behavioural theory (BT) to examine the beliefs and perceptions of a marginalised population towards community volunteering as a method of increasing the immunisation coverage of measles. Marginalised populations living in Kota Kinabalu, Sabah, more specifically, Malaysian citizens living in urban slums and squatter areas, as well as legal and illegal migrants, were extensively interviewed in person for this qualitative study. The 40 respondents were either the parents or primary caregivers of at least one child under the age of five. The components of the Health Belief Model were then used to examine the collected data. The respondents had poor awareness of the measles disease and perceived the disease as not severe, with some even refusing immunisation. The perceived barriers to receiving vaccinations included a nomadic lifestyle; issues with finances, citizenship status, language, and weather; failing to remember immunisation schedules; a fear of health care personnel; having too many children; and a lack of female autonomy in vaccine decision-making. However, the respondents were receptive towards community-based programmes and many welcomed a recall or reminder system, especially when the volunteers were family members or neighbours who spoke the same language and knew their village well. A few, however, found it awkward to have volunteers assisting them. Evidence-based decision making may increase measles immunisation coverage in marginalised populations. The components of the Health Belief Model validated that the respondents lacked awareness of the measles disease and viewed it and its effects as not severe. Therefore, future volunteer programmes should prioritise increasing the receptivity and self-control of marginalised populations to overcome barriers that hinder community involvement. A community-based volunteer programme is highly recommended to increase measles immunisation coverage.

Abstract
OBJECTIVES In the U.S., vaccination coverage is lower in rural versus urban areas. Spatial accessibility to immunization services has been a suspected risk factor for undervaccination in rural children. Our objective was to identify whether geographic factors, including driving distance to immunization providers, were associated with completion of recommended childhood vaccinations. METHODS We analyzed records from Montana's immunization information system for children born 2015-2017. Using geolocated address data, we calculated distance in road miles from children's residences to the nearest immunization provider. A multivariable log-linked binomial mixed model was used to identify factors associated with completion of the combined 7-vaccine series by age 24 months. RESULTS Among 26,085 children, 16,503 (63.3%) completed the combined 7-vaccine series by age 24 months. Distance to the nearest immunization provider ranged from 0 to 81.0 miles (median = 1.7; IQR = 3.2), with the majority (92.1%) of children living within 10 miles of a provider. Long distances (>10 miles) to providers had modest associations with not completing the combined 7-vaccine series (adjusted prevalence ratio [aPR]: 0.97, 95% confidence interval [CI]: 0.96-0.99). After adjustment for other factors, children living in rural areas (measured by rural-urban commuting area) were significantly less likely to have completed the combined 7-vaccine series than children in metropolitan areas (aPR: 0.88, 95% CI: 0.85-0.92). CONCLUSIONS Long travel distances do not appear to be a major barrier to childhood vaccination in Montana. Other challenges, including limited resources for clinic-based strategies to promote timely vaccination and parental vaccine hesitancy, may have greater influence on rural childhood vaccination.

Abstract
BACKGROUND AND PURPOSE Interventions are effective in promoting health behavior change to the extent that (a) intervention strategies modify targets (i.e., mechanisms of action), and (b) modifying targets leads to changes in behavior. To complement taxonomies that characterize the variety of strategies used in behavioral interventions, we outline a new principle that specifies how strategies modify targets and thereby promote behavior change. We distinguish two dimensions of targets-value (positive vs. negative) and accessibility (activation level)-and show that intervention strategies operate either by altering the value of what people think, feel, or want (target change) or by heightening the accessibility of behavior-related thoughts, feelings, and goals (target activation). METHODS AND RESULTS We review strategies designed to promote target activation and find that nudges, cue-reminders, goal priming, the question-behavior effect, and if-then planning are each effective in generating health behavior change, and that their effectiveness accrues from heightened accessibility of relevant targets. We also identify several other strategies that may operate, at least in part, via target activation (e.g., self-monitoring, message framing, anticipated regret inductions, and habits). CONCLUSIONS The Activation Vs. Change Principle (AVCP) offers a theoretically grounded and parsimonious means of distinguishing among intervention strategies. By focusing on how strategies modify targets, the AVCP can aid interventionists in deciding which intervention strategies to deploy and how to combine different strategies in behavioral trials. We outline a research agenda that could serve to further enhance the design and delivery of interventions to promote target activation.

Abstract
BACKGROUND Inequalities in access to and utilization of maternal and child health (MCH) care are hampering progress on the path to achieving the Sustainable Development Goals. In a number of Low- and Middle-Income Countries (LMICs) population subgroups at disproportionate risk of being left behind are the urban poor. Within this neglected group is the further neglected group of the homeless. Concomitantly, a number of interventions from the antenatal period onward have been piloted, tested, and scaled in these contexts. We carried out an overview of systematic reviews (SRs) to characterize the evidence around maternal and child health interventions relevant to urban poor homeless populations in LMICs. METHODS We searched Medline, Cochrane Library, Health Systems Evidence and EBSCOhost databases for SRs published between January 2009 and 2020 (with an updated search through November 2021). Our population of interest was women or children from urban poor settings in LMICs; interventions and outcomes corresponded with the World Health Organization's (WHO) guidance document. Each SR was assessed by two reviewers using established standard critical appraisal checklists. The overview was registered in PROSPERO (ID: CRD42021229107). RESULTS In a sample of 33 high quality SRs, we found no direct relevant evidence for pregnant and lactating homeless women (and children) in the reviewed literature. There was a lack of emphasis on evidence related to family planning, safe abortion care, and postpartum care of mothers. There was mixed quality evidence that the range of nutritional interventions had little, unclear or no effect on several child mortality and development outcomes. Interventions related to water, sanitation, and hygiene, ensuring acceptability of community health services and health promotion type programs could be regarded as beneficial, although location seemed to matter. Importantly, the risk of bias reporting in different reviews did not match, suggesting that greater attention to rigour in their conduct is needed. CONCLUSION The generalizability of existing systematic reviews to our population of interest was poor. There is a clear need for rigorous primary research on MCH interventions among urban poor, and particularly homeless populations in LMICs, as it is as yet unclear whether the same, augmented, or altogether different interventions would be required.

Abstract
INTRODUCTION Malaria is the second leading cause of death in children after diarrheal disease, with low- and middle-income countries (LMICs) accounting for over 9 in 10 incidence and deaths. Widespread acceptance and uptake of the RTS,S vaccine, recently approved by the world health organization (WHO), is projected to significantly reduce malaria incidence and deaths. Therefore, we conducted this systematic review and meta-analysis with the aim to determine the malaria vaccine acceptance rate and the factors associated with acceptance. METHODS We searched six databases including Google Scholar, PubMed, Cochrane, African Index Medicus, The Regional Office for Africa Library, and WHO Institutional Repository for Information Sharing (IRIS) to identify studies evaluating the malaria vaccine acceptance rate. This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Studies were included if they were original articles published in the English language in peer-reviewed journals and assessed the prevalence of willingness to accept a free malaria vaccine, and not qualitative. The risk of publication bias was checked using both Beggar's funnel plot and Egger's test, while the I2 statistic was used to assess the heterogeneity of the included studies. Study quality was determined using the Newcastle-Ottawa scale. A meta-analysis was performed using a random effects model to evaluate the pooled prevalence of malaria vaccine acceptance. The protocol for this article was registered prospectively on the International Prospective Register for Systematic Reviews (PROSPERO), with ID number CRD42022334282). RESULTS Our analysis included 11 studies with a total sample size of 14, 666 participants. The aggregate malaria vaccine acceptance rate was 95.3% (95% CI:93.0%-97.2%). Among the general population, the acceptance rate was 96.3% (95% CI:92.0%-99.0%) and among mothers, it was 94.4% (95% CI:90.8%-97.2%). By country, Nigeria had the highest acceptance rate (97.6%, 95% CI:96.0%-98.8%), followed by Ghana (94.6%, 95% CI:93.8%-95.3%) and Tanzania (92.5%, 95% CI:84.4%-97.8%). Sociodemographic determinants of vaccine acceptance included place of residence, tribe, age, sex, occupation, and religion. Reasons for low acceptance included safety concerns, efficacy profile, vaccine's requirement for multiple injections, and poor level of awareness. CONCLUSION Future efforts should be focused on identifying factors that may improve the actual uptake of the RTS,S vaccine in malaria-endemic communities.

Abstract
OBJECTIVE To support evidence-informed decision-making, we created an evidence gap map to characterise the evidence base on the effectiveness of interventions in improving routine childhood immunisation outcomes in low-income and middle-income countries (LMICs). METHODS We developed an intervention-outcome matrix with 38 interventions and 43 outcomes. We searched academic databases and grey literature sources for relevant impact evaluations (IEs) and systematic reviews (SRs). Search results were screened on title/abstract. Those included on title/abstract were retrieved for full review. Studies meeting the eligibility criteria were included and data were extracted for each included study. All screening and data extraction was done by two independent reviewers. We analysed these data to identify trends in the geographic distribution of evidence, the concentration of evidence across intervention and outcome categories, and attention to vulnerable populations in the literature. RESULTS We identified 309 studies, comprising 226 completed IEs, 58 completed SRs, 24 ongoing IEs and 1 ongoing SR. Evidence from IEs is heavily concentrated in a handful of countries in sub-Saharan Africa and South Asia. Among interventions, the most frequently evaluated are those related to education and material incentives for caregivers or health workers. There are gaps in the study of non-material incentives and outreach to vulnerable populations. Among outcomes, those related to vaccine coverage and health are well covered. However, evidence on intermediate outcomes related to health system capacity or barriers faced by caregivers is much more limited. CONCLUSIONS There is valuable evidence available to decision-makers for use in identifying and deploying effective strategies to increase routine immunisation in LMICs. However, additional research is needed to address gaps in the evidence base.

Abstract
Getting children vaccinated amidst prevailing barriers to immunisation has been challenging in both developed and developing countries. To address these problems, studies on parental reminder strategies were conducted to improve immunisation outcomes in children. These led to the development of different parental reminder interventions. This review systematically reviews different parental interventions and their cost implication for improved immunisations. Five online databases; Medline Complete, the Cumulative Index for Nursing and Allied Health Literature [CINAHL], Academic search premier, SPORTDiscus, and Health Source Nursing/Academic were searched using search terms. A total of 24 articles that met the inclusion criteria were included in this review. Studies that provided sufficient information were included for meta-analysis using Comprehensive Meta-Analysis version three, while narrative synthesis was used for the other studies. Results indicate that a heterogeneous and low-quality certainty of evidence on parental voice calls (OR 4.752, 95% CI 1.846-12.231, p = 0.001) exists in improving immunisation coverage. Regarding immunisation timeliness, a high-quality certainty of evidence on Short Message Services (SMS)-delivered health education messages (OR 2.711 95% CI 1.387-5.299, p = 0.004) had more effect on timely immunisation uptake. The average cost of SMS-delivered parental reminder interventions for improved immunisation outcomes was USD 0.50. The study concludes that mobile technology is a promising, cost-effective strategy for improved immunisation outcomes.

Abstract
Despite the implementation of widespread vaccination programs, the European Health Systems continue to experience care challenges attributable to organizational and structural issues. This study aimed to review the available data on aspects within the organizational and structural domains that might impact vaccination coverage. We searched a comprehensive range of databases from 1 January 2007 to 6 July 2021 for studies that reported quantitative or qualitative research on interventions to raise childhood vaccine coverage. Outcome assessments comprised organizational and structural factors that contribute to vaccine concern among pediatric parents, as well as data reported influencing the willingness to vaccinate. To analyze the risk of bias, the Ottawa, JBI’s (Joanna Briggs Institute) critical appraisal tool, and Amstar quality assessment were used accordingly. The inclusion criteria were met by 205 studies across 21 articles. The majority of the studies were conducted in the United Kingdom (6), the European Union (3), and Italy (3). A range of interventions studied in primary healthcare settings has been revealed to improve vaccination coverage rates including parental engagement and personalization, mandatory vaccination policies, program redesign, supply chain design, administering multiple/combination vaccines, improved vaccination timing and intervals, parental education and reminders, surveillance tools and Supplemental Immunisation Activity (SIA), and information model.

Abstract
PurposeA qualitative study can help in understanding the unpolluted perspectives of key stakeholders involved in the vaccination practices and can explore vital factors that could influence vaccination-related behaviors and their utilization. This study aims to document the perceptions of caretakers, community members and healthcare service providers related to childhood vaccination practices in slums under the national immunization program (NIP) of India.Design/methodology/approachThis was a qualitative community-based cross-sectional study. Focus group discussions with caretakers, community members and healthcare service providers were used to build a holistic, detailed description and analysis of the factors associated with childhood vaccination practices within its real-world context.FindingsLack of awareness, fear of adverse events following immunization, inappropriate timing of vaccination sessions, loss of daily earnings, migration, lack of good behavior of health staffs, shortage of logistics and vaccines, limited resources and infrastructures and high expectations of beneficiaries were some of the vital barriers impacting vaccination practices in slums.Research limitations/implicationsThough this study provides significant good information on the indicators that can be considered to improve the vaccination practices in any slum settings, it has is also a limitations too due to its setting. Therefore, one needs to be cautious while generalizing these results to other settings like rural. In addition, Though we believe that these strategies could be useful in any setting, it is also important to tailor these observations them as per the need of the society and the population. Also, this is a self-reported qualitative study and therefore the perspectives reported in this study need to be taken with caution. Further, low vaccination, poor awareness, compromised healthcare services, high expectations could be considered as a stigma/fear among the responders and therefore there is always a chance of underreporting. Thus, it would be important in future to conduct a study involving a broader group of people in society and to establish factors associated with the vaccination coverage. that can help in improvement of vaccination.Originality/valueInitiatives such as regular interactions at different levels, effective communication including reminders, behavior interventions, the continued supply of vaccines and logistics, additional resources for the vaccination program, incentives and recognition, extended sessions and people-friendly healthcare delivery system could be helpful to strengthen the routine vaccination practices in slums.

Abstract
OBJECTIVE Under-immunization increases the risk of acquiring vaccine-preventable diseases in children and the community. The targeted coverage rate for routine childhood immunization in Alberta, especially in disadvantaged communities in rural and remote geographic areas, has not been achieved for many years. This study was conducted to identify reasons for under-immunization in children in low socioeconomic status (SES) communities and propose suggestions to address issues/concerns identified by low SES parents for improving immunization coverage in their communities. METHODS Fourteen semi-structured phone interviews of low SES parents with under-immunized children living in rural and remote geographic areas in Northern Alberta were conducted. Transcripts were analyzed to identify relevant themes. RESULTS Busy lifestyles of many parents prevented them from taking their children to clinics for immunization, which were exacerbated by long distances to clinics, transportation issues, operating hours of clinics, and lack of reminders. Many disadvantaged parents also exhibited varying levels of vaccine hesitancy due to safety concerns, especially about newer vaccines, thereby causing some parents to delay immunizing their child intentionally. CONCLUSION Implementing procedures to alleviate access issues, such as offering extended operating hours, opening drop-in clinics/satellite clinics in distant areas, nurse visits to their homes, updating contact information of parents, frequent reminder options and addressing safety and effectiveness concerns about vaccines in plain language using evidence-based communication strategies can promote timely immunization among children of low SES parents.

Abstract
Progress has been made globally in improving the coverage of key maternal, newborn, and early childhood interventions in low-income and middle-income countries, which has contributed to a decrease in child mortality and morbidity. However, inequities remain, and many children and adolescents are still not covered by life-saving and nurturing care interventions, despite their relatively low costs and high cost-effectiveness. This Series paper builds on a large body of work from the past two decades on evidence-based interventions and packages of care for survival, strategies for delivery, and platforms to reach the most vulnerable. We review the current evidence base on the effectiveness of a variety of essential and emerging interventions that can be delivered from before conception until age 20 years to help children and adolescents not only survive into adulthood, but also to grow and develop optimally, support their wellbeing, and help them reach their full developmental potential. Although scaling up evidence-based interventions in children younger than 5 years might have the greatest effect on reducing child mortality rates, we highlight interventions and evidence gaps for school-age children (5-9 years) and the transition from childhood to adolescence (10-19 years), including interventions to support mental health and positive development, and address unintentional injuries, neglected tropical diseases, and non-communicable diseases.

Abstract
BACKGROUND Routine vaccination, a cost-effective means of preventing deadly childhood disease, has a low coverage in Nigeria. The study assessed the willingness of mothers to receive reminder messages for routine vaccination appointments in Northern Nigeria. METHODS A multi-centre cross-sectional study involving at least 363 mother-infant pairs per centre from five states in Northern Nigeria. Data collected include the socio-demographic details, responses on parental phone ownership, mothers' willingness to receive reminders for immunization appointments and the reminder type characteristics. Data analysis was done with SPSS. RESULTS Of the 1952 mother-infant pairs, ownership of at least one household phone was 97.7%. In total, 1613 (82.6%) mothers were willing to receive reminders. A majority (62.2%) of mothers preferred phone calls. A day before the vaccination appointment was the preferred timing (78.1%), and the predominant communication language was the local language for each region.The odds of being willing to receive reminders were 3.1 times, 2.6 times and 1.8 times higher in those with no formal education, primary education and secondary education, respectively, compared with mothers with tertiary education, each p < 0.05. Mothers who delivered at home were significantly less likely to want reminder messages (p = 0.03). CONCLUSION Eight of 10 women in Northern Nigeria are willing to receive a reminder for their child. The predominant mode of reminder preferred is phone calls using the local language. Deployment of mobile phone reminders strategy in Northern Nigeria as a means to improve vaccination uptake is feasible. The institution of this strategy can be in collaboration with service providers.

Effect of Mobile Phone Text Message Reminders on the Completion and Timely Receipt of Routine Childhood Vaccinations: Superiority Randomized Controlled Trial in Northwest Ethiopia. JMIR Mhealth Uhealth 2021; 9:e27603. [PMID: 34128813 PMCID: PMC8277338 DOI: 10.2196/27603] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 04/18/2021] [Accepted: 05/11/2021] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Nonattendance at vaccination appointments is a big challenge for health workers as it is difficult to track routine vaccination schedules. In Ethiopia, 3 out of 10 children have incomplete vaccination and the timely receipt of the recommended vaccines is low. Thus, innovative strategies are required to reach the last mile where mobile technology can be effectively utilized to achieve better compliance. Despite this promising technology, little is known about the role of text message-based mobile health interventions in improving the complete and timely receipt of routine childhood vaccinations in Ethiopia. OBJECTIVE This trial aimed to determine the effect of mobile phone text message reminders on the completion and timely receipt of routine childhood vaccinations in northwest Ethiopia. METHODS A two-arm, parallel, superiority randomized controlled trial was conducted in 9 health facilities in northwest Ethiopia. A sample size of 434 mother-infant pairs was considered in this trial. Randomization was applied in selected health facilities during enrollment with a 1:1 allocation ratio by using sealed and opaque envelopes. Participants assigned to the intervention group received mobile phone text message reminders one day before the scheduled vaccination visits. Owing to the nature of the intervention, blinding of participants was not possible. Primary outcomes of full and timely completion of vaccinations were measured objectively at 12 months. A two-sample test of proportion and log-binomial regression analyses were used to compare the outcomes between the study groups. A modified intention-to-treat analysis approach was applied and a one-tailed test was reported, considering the superiority design of the trial. RESULTS A total of 426 participants were included for the analysis. We found that a higher proportion of infants in the intervention group received Penta-3 (204/213, 95.8% vs 185/213, 86.9%, respectively; P<.001), measles (195/213, 91.5% vs 169/213, 79.3%, respectively; P<.001), and full vaccination (176/213, 82.6% vs 151/213, 70.9%, respectively; P=.002; risk ratio 1.17, 95% lower CI 1.07) compared to infants in the usual care group. Similarly, a higher proportion of infants in the intervention group received Penta-3 (181/204, 88.7% vs 128/185, 69.2%, respectively; P<.001), measles (170/195, 87.1% vs 116/169, 68.6%, respectively; P<.001), and all scheduled vaccinations (135/213, 63.3% vs 85/213, 39.9%, respectively; P<.001; risk ratio 1.59, 95% lower CI 1.35) on time compared to infants in the usual care group. Of the automatically sent 852 mobile phone text messages, 764 (89.7%) were delivered successfully to the participants. CONCLUSIONS Mobile phone text message reminders significantly improved complete and timely receipt of all recommended vaccines. Besides, they had a significant effect in improving the timely receipt of specific vaccines. Thus, text message reminders can be used to supplement the routine immunization program in resource-limited settings. Considering different contexts, studies on the implementation challenges of mobile health interventions are recommended.

Abstract
INTRODUCTION Measles, mumps, and rubella incidence decreased drastically following vaccination programs' implementation. However, measles and mumps' resurgence was recently reported, outbreaks still occur, and challenges remain to control these diseases. AREAS COVERED This qualitative narrative review provides an objective appraisal of the literature regarding current challenges in controlling measles, mumps, rubella infections, and interventions to address them. EXPERT OPINION While vaccines against measles, mumps, and rubella (including trivalent vaccines) are widely used and effective, challenges to control these diseases are mainly related to insufficient immunization coverage and changing vaccination needs owing to new global environment (e.g. traveling, migration, population density). By understanding disease transmission peculiarities by setting, initiatives are needed to optimize vaccination policies and increase vaccination coverage, which was further negatively impacted by COVID-19 pandemic. Also, awareness of the potential severity of infections and the role of vaccines should increase. Reminder systems, vaccination of disadvantaged, high-risk and difficult-to-reach populations, accessibility of vaccination, healthcare infrastructure, and vaccination services management should improve. Outbreak preparedness should be strengthened, including implementation of high-quality surveillance systems to monitor epidemiology. While the main focus should be on these public health initiatives to increase vaccination coverage, slightly more benefits could come from evolution of current vaccines.

Abstract
RATIONALE Evidence-based medicine (EBM), the dominant approach to assessing the effectiveness of clinical and public health interventions, focuses on the results of association studies. EBM+ is a development of EBM that systematically considers mechanistic studies alongside association studies. AIMS AND OBJECTIVES To explore examples of the importance of mechanistic evidence to coronavirus research. METHODS We have reviewed the mechanistic evidence in four major areas that are relevant to the management of COVID-19. RESULTS AND CONCLUSIONS (a) Assessment of combination therapy for MERS highlights the need for systematic assessment of mechanistic evidence. (b) That hypertension is a risk factor for severe disease in the case of SARS-CoV-2 suggests that altering hypertension treatment might alleviate disease, but the mechanisms are complex, and it is essential to consider and evaluate multiple mechanistic hypotheses. (c) Confidence that public health interventions will be effective requires a detailed assessment of social and psychological components of the mechanisms of their action, in addition to mechanisms of disease. (d) In particular, if vaccination programmes are to be effective, they must be carefully tailored to the social context; again, mechanistic evidence is crucial. We conclude that coronavirus research is best situated within the EBM+ evaluation framework.

Abstract
BACKGROUND Immunization is a significant public health intervention to reduce child mortality and morbidity. However, its coverage, in spite of free accessibility, is still very low in developing countries. One of the primary reasons for this low coverage is the lack of analysis and proper utilization of immunization data at various healthcare facilities. PURPOSE In this paper, the existing machine learning-based data analytics techniques have been reviewed critically to highlight the gaps where this high potential data could be exploited in a meaningful manner. RESULTS It has been revealed from our review that the existing approaches use data analytics techniques without considering the complete complexity of Expanded Program on Immunization which includes the maintenance of cold chain systems, proper distribution of vaccine and quality of data captured at various healthcare facilities. Moreover, in developing countries, there is no centralized data repository where all data related to immunization is being gathered to perform analytics at various levels of granularities. CONCLUSION We believe that the existing non-centralized immunization data with the right set of machine learning and Artificial Intelligence-based techniques will not only improve the vaccination coverage but will also help in predicting the future trends and patterns of its coverage in different geographical locations.

Abstract
This paper studies non-adherence in the Danish Childhood Vaccination Program using a nationwide introduction of a vaccination reminder letter policy and administrative data from 2011-2017. First, I provide causal estimates of how the reminder letter policy affects vaccination adherence using a Regression Discontinuity Design (RDD). Second, I link parental responses to the reminder letter to parents' causes for being non-adherent. I find that the reminder letter policy positively affects adherence. However, 72% of non-adherent parents are non-responsive to the reminder letter indicating that reluctance and not inattention is the leading cause for non-adherence. Thus, other policies beyond reminder letters - such as mandatory vaccination laws - are necessary to substantially increase vaccination coverage.

Abstract
Vaccine hesitancy (VH) is a pervasive issue resulting in the delay or refusal of vaccines, which are known to protect against life-threatening diseases. The purpose of this quality improvement project was to determine if early identification of VH using the Parent Attitudes about Childhood Vaccines survey and targeted interventions would decrease VH scores. Of the 70 total participants, 11 participants were VH in the preintervention survey group; of those, nine (81.8%) were not VH in the postintervention survey group, and two (18.2%) remained VH (p = .004) after the intervention. Routine screening for VH using the Parent Attitudes about Childhood Vaccines survey and implementing interventions successfully decreased VH scores and improved vaccine compliance.

Abstract
Vaccination coverage among children in kindergarten varies across the country and within states. We surveyed a convenience sample of kindergarten school nurses to investigate self-reported vaccination-related activities conducted at schools nationwide. The majority of the 1,435 kindergarten school nurses responding reported that their schools communicate with parents and guardians of undervaccinated students by phone (96%), postal mail (67%), newsletters (61%), and e-mail (59%). Most respondents reported documenting vaccination coverage in electronic systems (85%) and sharing coverage reports with health departments (69%). A total of 41% of school nurses worked with external partners for vaccination efforts, the most common support received from partners being vaccine administration (38%) and providing materials/vaccines (21%). School nurses also reported that 95% of kindergartners were up to date for all vaccines. School-based vaccination-related activities are essential to sustaining high levels of vaccination coverage for the protection of children at schools and in the broader community.

Abstract
Background In Denmark, vaccination coverage is measured using the Danish Vaccination Register (DDV). In general, the vaccination coverage is high, but for some vaccinations, the coverage is suboptimal with geographical variation. This study aims to validate the vaccination coverage of the 5-year booster and identify overall reasons for non-vaccination in Copenhagen. Methods We validated the coverage of the 5-year tetanus, diphtheria, pertussis and polio booster for children born in 2010 and living in Copenhagen municipality in 2018, an area with low coverage (current estimate: 89%). We identified all children born in 2010 in the Civil Registration System and sent an electronic questionnaire to parents of children without a record of the 5-year booster in the DDV. Results Parents of 692 children were contacted and 49% participated. Of those, 186 (55%) reported that the child was vaccinated: 61% by their general practitioner and 34% abroad. The most common reason for non-vaccination was forgetfulness (31%), 26% did not want their child vaccinated and 17% had migrated from abroad and were not aware of the vaccination schedule. Considering only children with documentation for the vaccination, the corrected vaccination coverage was 91%. Conclusions We conclude that the coverage of the 5-year booster in Copenhagen is currently underestimated and should be adjusted by 2%. We recommend increased awareness from general practitioners and tailored communication about the vaccination programme targeting immigrants in Denmark.

Abstract
Parental vaccine hesitancy is becoming an increasingly important public health concern in the United States. In March 2020, an assessment of the latest CDC National Immunization Survey data found that more than one-third of U.S. children between the ages of 19 and 35 months were not following the recommended early childhood immunization schedule. Furthermore, a 2019 national survey found that approximately 1 in 4 parents reported serious concerns towards vaccinating their children. Vaccine hesitancy is now associated with a decrease in vaccine coverage and an increase in vaccine-preventable disease outbreaks and epidemics in the United States. Many studies have focused on understanding and defining the new socio-medical term, vaccine hesitancy; few have attempted to summarize past and current health communication interventions and strategies that have been successful or unsuccessful in tackling this growing phenomenon. This systematic literature review will attempt to aid public health professionals with a catalogue of health communication interventions and strategies to ultimately address and prevent parental vaccine hesitancy in the long term. Out of 1239 search results, a total of 75 articles were included for analysis, ranging from systematic reviews, quantitative surveys, and experimental designs to ethnographic and qualitative studies. For the presentation of results, a taxonomy was used to organize communication interventions according to their intended purpose. The catalogue of interventions was further broken down into specific components and themes that were identified in the literature as essential to either the success or failure in preventing and addressing parental vaccine hesitancy towards childhood vaccines.

Abstract
Background Inability to track children’s vaccination history coupled with parents’ lack of awareness of vaccination due dates compounds the problem of low immunization coverage and timeliness in developing countries. We evaluated the impact of two types of silicone immunization reminder bracelets for children in improving immunization coverage and timeliness of Pentavalent-3 and the Measles-1 vaccines. Methods Children < 3 months were enrolled in either of the 2 intervention groups (Alma Sana Bracelet Group and Star Bracelet Group) or the Control group. Children in the intervention groups were provided the two different bracelets at the time of recruitment. Each time the child visited the immunization center, a hole was perforated in the silicone bracelet to denote vaccine administration. Each child was followed up till administration of Measles-1 vaccine or till 12 months of age (if they did not come to the center for vaccination). Data was analyzed using the intention-to-treat population between groups. The unadjusted and adjusted Risk Ratios (RR) and 95% confidence interval (CI) for Pentavalent-3 and Measles-1 coverage at 12 months of age were estimated through bivariate and multivariate analysis. Time-to-Pentavalent-3 and Measles-1 immunization curves were calculated using the Kaplan–Meier method. Results A total of 1,445 children were enrolled in the study between July 19, 2017 and October 10, 2017. Baseline characteristics among the three groups were similar. Up-to-date coverage for the Pentavalent-3 /Measles-1 vaccine at 12 months of age was 84.6%/72.0%, 85.4%/70.5% and 83.0%/68.5% in Alma Sana Bracelet group, Star Bracelet group and Control group respectively but the differences were not statistically significant. In the multivariate analysis, neither the Alma Sana bracelet (adjusted RR = 1.01; 95% CI: 0.96-1.06), (adjusted RR: 1.05; 95% CI: 0.97-1.13) nor the Star bracelet (adjusted RR = 1.01; 95% CI: 0.96-1.06) (adjusted RR: 1.03; 95% CI: 0.95-1.11) was significantly associated with Pentavalent-3 vaccination or Measles-1 vaccination. Conclusion Although we did not observe any significant impact of the bracelets on improved immunization coverage and timeliness, our findings add to the existing literature on innovative, low cost reminders for health and make several suggestions for enhancing practical implementation of these tools.

Abstract
BACKGROUND Although Personal Electronic Health Records (PEHR) have been identified as innovative tools enabling the provision of patient-centered care and prevention, evidence on the impact of their use is scant. With PEHRs being more and more marketed as easily implementable and cost-effective instruments to provide people with direct control on their health, the question on whether their use might be associated with the priority to improve vaccine coverage arises. METHODS We conducted a systematic review following the PRISMA guidelines to retrieve, quantitatively pool and critically appraise the effectiveness of PEHR access on vaccine uptake. Analysis on PEHR effectiveness were carried out for the following comparison strata: i) PEHR access vs no intervention (standard care, no access to PEHR), ii) PEHR access only vs access to PEHR with additional features (e.g. health education materials, active reminders). RESULTS Of 3114 identified citations, 8 studies were included, the majority published in the US and before 2015; 62% were randomized trials, the rest having an observational study design. Evidence suggests a moderate positive impact of PEHR access in increasing vaccine uptake, with data available for influenza and pneumococcal vaccines, diabetic patients and childhood immunization. Pooled data report the addition of digital communication features, i.e. the delivery of educational messages, reminders and availability of scheduling features might increase vaccine uptake, as compared to PEHR access alone. However, evidence is not conclusive. CONCLUSION While immunization programs are struggling to achieve optimal coverage targets, it seems the potential of PEHRSs supporting informed adherence to vaccines recommendations is neither fully exploited nor explored. Which factors mediate the association between PEHRs access and vaccine uptake? Which PEHRs' design and functional components can maximize their impact? On which target populations? Which PEHR models works better for high-risk populations? Our findings can only partially answer those questions and further experimental research is needed.

Abstract
BACKGROUND Vaccination is a critical step in reducing child mortality; however, vaccination rates have declined in many countries in recent years. This decrease has been associated with an increase in the outbreak of vaccine-preventable diseases. The potential for leveraging mobile platforms to promote vaccination coverage has been investigated in the development of numerous mobile apps. Although many are available for public use, there is little robust evaluation of these apps. OBJECTIVE This systematic review aimed to assess the effectiveness of apps supporting childhood vaccinations in improving vaccination uptake, knowledge, and decision making as well as the usability and user perceptions of these apps. METHODS PubMed, Excerpta Medica Database (EMBASE), Web of Science, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and Education Resources Information Center (ERIC) databases were systematically searched for studies published between 2008 and 2019 that evaluated childhood vaccination apps. Two authors screened and selected studies according to the inclusion and exclusion criteria. Data were extracted and analyzed, and the studies were assessed for risk of bias. RESULTS A total of 28 studies evaluating 25 apps met the inclusion criteria and were included in this analysis. Overall, 9 studies assessed vaccination uptake, of which 4 reported significant benefits (P<.001 or P=.03) of the implementation of the app. Similarly, 4 studies indicated a significant (P≤.054) impact on knowledge and on vaccination decision making. Patient perceptions, usability, and acceptability were generally positive. The quality of the included studies was found to be moderate to poor, with many aspects of the methodology being unclear. CONCLUSIONS There is little evidence to support the use of childhood vaccination apps to improve vaccination uptake, knowledge, or decision making. Further research is required to understand the dichotomous effects of vaccination-related information provision and the evaluation of these apps in larger, more robust studies. The methodology of studies must be reported more comprehensively to accurately assess the effectiveness of childhood vaccination apps and the risk of bias of studies.

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

Abstract
BACKGROUND Parents have reported that they want to learn how to reduce pain in infants during vaccinations. Our objective was to compare different levels of intensity of postnatal education about pain mitigation on parental self-reported use of interventions at future infant vaccinations. METHODS We conducted a longitudinal, 3-group parallel, add-on, randomized controlled trial on the postnatal ward of a hospital. New mothers, unaware of the hypothesis, were randomly assigned to 1 of 3 intervention groups and 3 follow-up groups (i.e., 9 groups, 3 × 3). The 3 intervention groups were control (general immunization information), pain pamphlet (pain mitigation information), and pain pamphlet and pain video (pain mitigation information). Both pain mitigation education groups also received general immunization information. The 3 follow-up groups were 2-, 4- and 6-month infant vaccinations. Mothers reported use of breastfeeding, sucrose and topical anesthetics during infant vaccinations in a telephone survey. RESULTS Of 3420 participants, follow-up was available for 2549 (75%): 36.1%, 34.2% and 29.7% reported on pain mitigation practices at 2-, 4- and 6-month vaccinations, respectively (p = 0.9). Maternal characteristics did not differ (p > 0.05): mean age, 33.6 years; 58% were primipara. Utilization of any intervention (breastfeeding, sucrose or topical anesthetics) was 53.2%, 61.4% and 63.0% for control, pain pamphlet, and pain pamphlet and pain video groups, respectively (p < 0.001); both pain education groups had higher utilization than the control group, but did not differ from one another. Uptake differed among intervention groups at 2 and 4 months but not at 6 months. INTERPRETATION Hospital-based postnatal education increased parental use of pain interventions at infant vaccinations and can be added to existing education. TRIAL REGISTRATION ClinicalTrials.gov, no. NCT01937143.

Abstract
Immunisation at the earliest appropriate age and high levels of vaccine coverage at milestone ages are important in preventing the spread of vaccine-preventable diseases. At the Central Coast Public Health Unit, the authors sought to determine if follow-up of children said by the Australian Childhood Immunisation Register (ACIR) to be overdue for vaccination improved both of these factors. In a quality improvement activity, monthly ACIR lists of overdue Central Coast children aged 9 to 10 months of age were examined. The study alternated three months of intervention with three months of no intervention. The intervention was designed to find evidence of vaccination, first from the last known provider, and then if this was unsuccessful, from the parent. If no information was available, a letter was sent to the parents. If the child was indeed vaccinated, the register was updated. If the child was missing any vaccinations, the parent(s) were encouraged to complete the schedule. On reviewing routinely-published quarterly ACIR data at three-monthly intervals for 24 months after the intervention (or non-intervention), timeliness of vaccination improved in the intervention cohort. Central Coast fully vaccinated rates diverged from NSW rates during the study. In addition, the ACIR quarters that contained two out of three months of intervention rather than one out of three months of intervention had the highest rates of fully vaccinated children. The authors concluded that the intervention improved both timeliness of vaccination and the proportion of fully vaccinated children.

Abstract
Rheumatic heart disease, as a result of a single or recurrent episode of acute rheumatic fever (ARF), remains a significant cause of morbidity and mortality in northern and remote Australia; ARF has a peak incidence among 5-14-year-old Aboriginal and Torres Strait Islander children. Long-term regular benzathine penicillin G injections are the only currently successful secondary prevention strategy; however, rates of adherence remain critically low. In contrast, rates of adherence to immunisations on the National Immunisation Program (NIP) Schedule are high, even among this target population. This article compares strategies used to implement and improve ARF secondary prophylaxis with those used in the NIP. Some successful NIP strategies, such as Service Incentive Payment for health providers, home-visiting delivery models and integration into the National Immunisation Register, if applied to ARF secondary prophylaxis have the potential to improve benzathine penicillin G adherence.

Abstract
Introduction: Systematic reviews (SRs) are the backbone of evidence-based health care, but no gold standard exists to assess their methodological quality. Although the AMSTAR tool is accepted for analyzing the quality of SRs, the ROBIS instrument was recently developed. This study compared the capacity of both instruments to capture the quality of SRs of interventions for improving vaccination coverage.Methods: We conducted a comprehensive literature search in the Cochrane Library and PubMed. Two reviewers independently screened the search output, assessed study eligibility, and extracted data from eligible SRs; resolving differences through consensus. We conducted Principal Component Analysis (PCA) in Stata 14 to determine similarities and differences between AMSTAR and ROBIS.Results: A total of 2322 records were identified through the search and 75 full-text publications were assessed for eligibility, of which 57 met inclusion criteria. Using AMSTAR, we found 32%, 60% and 9% of SRs to have high, moderate and low quality, respectively. With ROBIS, we judged 74%, 14% and 12% of SRs to have low, unclear and high risk of bias. PCA showed that SRs with low risk of bias in ROBIS clustered together with SRs having high-quality in AMSTAR, and SRs with high risk of bias in ROBIS clustered with low-quality SRs in AMSTAR.Conclusions: Our findings suggest that there is an association between methodological quality and risk of bias in SRs of interventions focused on improving vaccination coverage. Therefore, either AMSTAR or ROBIS checklists can be used to evaluate methodological quality of SRs in vaccinology.

Abstract
BACKGROUND The World Health Organization estimates that 29% of under-five mortality could be prevented with existing vaccines. However, non-consistent attendance for immunization appointments remains a global challenge to healthcare providers. Thus, innovative strategies are required to reach the last mile where technology could be effectively utilized to achieve better compliance with children immunization schedules. Therefore, the aim of the review was to systematically collect and summarize the available evidence on the effectiveness of text message reminders on childhood vaccination. METHODS This review was conducted according to a priori published protocol on PROSPERO. A systematic literature search of databases (PubMed/MEDLINE, EMBASE, Cochrane/Wiley library, and Science direct) was conducted. Eligibility and risk of bias assessments were performed independently by two reviewers. PRISMA flow diagrams were used to summarize the study selection process. Taking into account the level of heterogeneity, a random effects model was used and risk ratios with their 95% CI were used to present the pooled estimates. To investigate the sources of heterogeneity, subgroup analysis and meta-regression analysis were also considered. In this review, publication bias was assessed statistically using Harbord test. RESULTS A total of 1771 articles were searched. Out of those 1771 articles, 558 duplicated articles were removed. About 1213 articles were further screened, and finally, ten articles met the inclusion criteria. The meta-analysis showed that there is a significant effect of text message reminders on childhood vaccination coverage (RR = 1.11; 95% CI 1.05-1.17) with a moderate level of heterogeneity (I2 = 64.3%, P = 0.003). The results from the Harbord test suggested that there is no evidence for publication bias (P = 0.340). CONCLUSION This review highlights the potential benefits of incorporating mobile text message reminders into the standard management of childhood immunizations, especially in low- and middle-income countries. The frequency and timing of the text message reminders are also crucial in determining the effectiveness of text message reminders. Hence, mHealth interventions deserve more attention as a potential innovation to improve healthcare programs. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42017074230.

Abstract
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.

Abstract
BACKGROUND Immunization in Canada is recommended not mandated, granting parents discretionary decision-making power regarding their child's immunization status. Uptake of childhood immunization at present falls below national targets. Nurses who interact with parents in the clinical setting may witness parents' decision-making experiences, attitudes, and opinions inclusive of vaccine hesitancy. PURPOSE The aim of this study is to understand parents' and nurses' experiences of decision-making about childhood immunization, specifically measles-mumps-rubella and/or diphtheria-tetanus-acellular pertussis. METHODS Thorne's interpretative description approach was used to understand parents' and nurses' experiences and perspectives about immunization. The sample was 6 nurses and 16 parents residing in northeastern Ontario. RESULTS Common to all participants was the goal of protection. Motivated by child protection, parents carried out three broad actions, searching for information, deliberating the information and sources to determine the relative benefits and risks of immunization, and bearing responsibility for their decision to accept, delay, or decline immunization. Nurses were motivated by child protection and population health. CONCLUSION Implications for nursing included integration of immunization competencies in nursing curricula, ongoing professional development, validation of parental actions for child protection, nurse-led education sessions, and engaging parents through social media to support access to reputable information.

Abstract
Tetanus, diphtheria, and acellular pertussis (Tdap) vaccination and influenza vaccination are recommended during pregnancy primarily to prevent influenza and pertussis in mothers and their infants. This study examines associations between prenatal Tdap vaccination and influenza vaccination of mothers and hepatitis B vaccination of their infants. A retrospective cohort study was conducted using data from electronic medical records from 15,468 deliveries to 14,925 mothers occurring April 2, 2014-December 3, 2016 at a university hospital in Texas. Hepatitis B vaccine receipt in the first 3 days of life was dichotomized. Margins post-estimation commands in Stata SE 15.1 were used to obtain predicted probabilities and risk differences after estimating odds ratios in logistic regression with robust variance estimates. Adjusted models included maternal age, race/ethnicity, Medicaid use, year of delivery, parity, and gravidity. Infants of mothers who received prenatal influenza vaccination in the 2014-2015 and 2015-2016 influenza seasons were more likely than those of mothers who did not to receive a hepatitis B vaccine in their first 3 days of life (adjusted risk difference (RD) 2.8%, 95% confidence interval (CI) 1.5-4.1% and RD 2.2%, 95% CI 0.9-3.5%, respectively). Hepatitis B vaccination was also higher among infants of Tdap-eligible mothers who received prenatal Tdap vaccination during pregnancy compared to those of mothers who did not (adjusted RD 9.1%, 95% CI 7.6-10.5%). Overall, prenatal vaccination was significantly associated with uptake of infant hepatitis B vaccine.

Abstract
AIMS Almost, one third of the world's urban population resides in slums and the number would double by 2030. Slums denotes collection of people from various communities having a meagre income and living in unhygienic conditions thus making themselves most vulnerable for outbreaks of communicable diseases. India contributes substantially to the global disease burden and under-five mortality rates i.e. 20% attributable to vaccine preventable diseases. Immunization plays a crucial role in combating high childhood mortality rates attributable to vaccine preventable diseases across the globe. This systematic review, provides insights on immunization status in slums, identifies various factors influencing it thus, exploring opportunities that may be available to improve vaccination coverage under the National Immunization Program. METHODS Taking into account the above aspects, a review of literature was undertaken in various databases that included studies published between 2006 and 2017. RESULTS In India, ~33% of the urban population lives in slums with suboptimal vaccination coverage ranging from 14% to upto 90%. Few of the important causes for low coverage included socioeconomic factors such as poor community participation, lack of awareness, frequent migration, and loss of daily income. Hence, mere presence of vaccines in the National Immunization Program doesn't do the job, there is a definite unmet need to emphasize upon the importance of immunization among slums dwellers and take necessary steps. For instance, delivering immunization services at the doorstep (e.g. pulse polio program), community-based education, text messaging as reminders and incentivized immunization services are some of the opportunities that can be explored and implemented to improve immunization status in the slums. CONCLUSION Thus, in addition to inclusion of more and more vaccines in the National Immunization Program, there is a definite need to focus on people living in high risk areas in order to improve coverage and healthcare indicators.

Abstract
BACKGROUND Many children in developed countries do not receive recommended vaccines on time. However, knowledge about factors related to timeliness remains limited. Quantifying the relative impact of parental attitudes compared with socio-demographic factors for delayed immunization would inform policy responses. METHODS Participants in the nationally representative Longitudinal Study of Australian Children were matched with their vaccination histories in the Australian Childhood Immunisation Register (N = 4,121). Information about the children and their families were collected in face-to-face interviews in 2003-2004. We considered whether children had completed the primary course for each recommended antigen due by 6 months old. Children were categorized as either fully immunized, delayed, or totally non-immunized. The outcome was examined using logistic regression. Population attributable fractions were estimated for key predictors. RESULTS Delayed immunization was significantly associated with indicators of social disadvantage as well as parental disagreement with immunization. Attributable fractions for delayed immunization included lone motherhood (3.8%; 95% confidence interval CI [0.8, 6.7]), larger family size (39.5%; 95% CI [31.2, 46.8]), residential mobility (3.3%; 95% CI [0.1, 6.5]), lack of private hospital insurance (9.4%; 95% CI [0.7, 17.3]), a medical condition in the child (2.0%; 95% CI [0.2, 3.9]), and parental disagreement with immunization (2.1%; 95% CI [0.3, 3.9]). CONCLUSIONS Parental attitudes accounted for a relatively small percentage of delayed infant immunization. In contrast, many children who did not receive vaccines on time were characterized by social disadvantage, especially larger family size. Researchers and policy-makers should consider how to make timely immunization easier for busy parents.

Abstract
Vaccination has been identified many decades ago as an effective means to prevent several diseases. However, in France, there is an emergence of vaccine hesitancy, that has caused a reduction of vaccination coverage rates. This issue reduces the effectiveness of the immunization process, and represents a real threat to public health that should be urgently addressed. The purpose of this review is to present actions that have been taken to fight against vaccine hesitancy and thus enhance vaccine uptake. The results indicate that different strategies have been proposed to reach this goal, mainly by vaccination campaigns. These findings highlight the strong implication of national health authorities and the medical staff of hospitals and health-care centers. However, actions implemented should be part of a long-term approach, and further studies are required to identify the most effective strategies to address vaccine hesitancy.

Abstract
We aimed to identify sociodemographic predictors of compliance after receiving a personalised reminder on lacking vaccinations against MMR (Measles, Mumps, Rubella) and/or HPV (Human Papilloma Virus) among parents of Danish adolescent girls. A nationwide register-based study, including all 14-year-old girls (15 May 2014-14 May 2015) lacking either MMR, HPV-vaccination or both. Vaccination-compliance following a postal reminder was modelled using multivariable logistic regression and included the following socio-demographic predictors: maternal age, education, employment and ethnicity. Birth order, number of siblings, family-structure, location of residence, and household income. The parents of 9692 girls received a reminder. Out of 4940 exclusively lacking an HPV-vaccine, 15.3% were subsequently vaccinated. Among 2026 only lacking an MMR vaccination, 8.5% were vaccinated. Among 2726 girls lacking both, 5% received an HPV, 4.4% an MMR and 5.4% received both vaccinations. We identified sociodemographic differences between reminderletter-compliers and non-compliers, also according to vaccination types. Non-western descendants were more likely to receive HPV-vaccination, although the association was only significant for those who only lacked HPV (OR 2.02, 95% 1.57-2.59). For girls only lacking an MMR, regional differences were identified. Among girls lacking both vaccines, girls of mothers with intermediate (OR 0.63, 0.42-0.95) or basic education (OR 0.43, 0.24-0.75) were less likely to be vaccinated compared to girls of higher educated mothers. Reminders were in particular effective in increasing HPV uptake among immigrants of non-Western ethnicity. We found reminders to be less effective among less educated mothers whose daughters lacked both vaccines. To increase the coverage in this group, additional interventions are needed.

Abstract
Public health benefits of childhood vaccinations risk being derailed by low vaccination coverage in low and middle-income countries. One reason for the low coverage is poor parental knowledge of the importance of completing vaccination schedules. We therefore assessed the effects on childhood vaccination coverage, of educating parents and other persons assuming the parental role. We prospectively registered the systematic review, published the protocol, and used standard Cochrane methods to collect and synthesise the evidence. We found six eligible randomised trials with 4248 participants. Three trials assessed health-facility based education of mothers on the importance of completing vaccination schedules; immediately after birth and three months later (one study) or during the first vaccination visit (two studies). The other trials assessed community-based education, including information campaigns on the importance of vaccines using audiotaped presentations and leaflet distributions (one study); structured group discussions on benefits and costs of childhood vaccination and local action plans for improving vaccine uptake (one study); and home-based information sessions using graphic cards showing benefits and costs of childhood vaccinations and location of vaccination centres (one study). Combining the data shows that these interventions lead to substantial improvements in childhood vaccination coverage (relative increase 36%, 95% confidence interval 14% to 62%). There was no difference between the effects of community-based and facility-based education. Therefore, education in communities and health facilities on the importance of childhood vaccinations should be integrated into all vaccination programmes in low and middle-income countries; accompanied by robust monitoring of impacts and use of data for action.

Abstract
BACKGROUND Early childhood vaccination is an essential global public health practice that saves two to three million lives each year, but many children do not receive all the recommended vaccines. To achieve and maintain appropriate coverage rates, vaccination programmes rely on people having sufficient awareness and acceptance of vaccines.Face-to-face information or educational interventions are widely used to help parents understand why vaccines are important; explain where, how and when to access services; and address hesitancy and concerns about vaccine safety or efficacy. Such interventions are interactive, and can be adapted to target particular populations or identified barriers.This is an update of a review originally published in 2013. OBJECTIVES To assess the effects of face-to-face interventions for informing or educating parents about early childhood vaccination on vaccination status and parental knowledge, attitudes and intention to vaccinate. SEARCH METHODS We searched the CENTRAL, MEDLINE, Embase, five other databases, and two trial registries (July and August 2017). We screened reference lists of relevant articles, and contacted authors of included studies and experts in the field. We had no language or date restrictions. SELECTION CRITERIA We included randomised controlled trials (RCTs) and cluster-RCTs evaluating the effects of face-to-face interventions delivered to parents or expectant parents to inform or educate them about early childhood vaccination, compared with control or with another face-to-face intervention. The World Health Organization recommends that children receive all early childhood vaccines, with the exception of human papillomavirus vaccine (HPV), which is delivered to adolescents. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Two authors independently reviewed all search results, extracted data and assessed the risk of bias of included studies. MAIN RESULTS In this update, we found four new studies, for a total of ten studies. We included seven RCTs and three cluster-RCTs involving a total of 4527 participants, although we were unable to pool the data from one cluster-RCT. Three of the ten studies were conducted in low- or middle- income countries.All included studies compared face-to-face interventions with control. Most studies evaluated the effectiveness of a single intervention session delivered to individual parents. The interventions were an even mix of short (ten minutes or less) and longer sessions (15 minutes to several hours).Overall, elements of the study designs put them at moderate to high risk of bias. All studies but one were at low risk of bias for sequence generation (i.e. used a random number sequence). For allocation concealment (i.e. the person randomising participants was unaware of the study group to which participant would be allocated), three were at high risk and one was judged at unclear risk of bias. Due to the educational nature of the intervention, blinding of participants and personnel was not possible in any studies. The risk of bias due to blinding of outcome assessors was judged as low for four studies. Most studies were at unclear risk of bias for incomplete outcome data and selective reporting. Other potential sources of bias included failure to account for clustering in a cluster-RCT and significant unexplained baseline differences between groups. One cluster-RCT was at high risk for selective recruitment of participants.We judged the certainty of the evidence to be low for the outcomes of children's vaccination status, parents' attitudes or beliefs, intention to vaccinate, adverse effects (e.g. anxiety), and immunisation cost, and moderate for parents' knowledge or understanding. All studies had limitations in design. We downgraded the certainty of the evidence where we judged that studies had problems with randomisation or allocation concealment, or when outcomes were self-reported by participants who knew whether they'd received the intervention or not. We also downgraded the certainty for inconsistency (vaccination status), imprecision (intention to vaccinate and adverse effects), and indirectness (attitudes or beliefs, and cost).Low-certainty evidence from seven studies (3004 participants) suggested that face-to-face interventions to inform or educate parents may improve vaccination status (risk ratio (RR) 1.20, 95% confidence interval (CI) 1.04 to 1.37). Moderate-certainty evidence from four studies (657 participants) found that face-to-face interventions probably slightly improved parent knowledge (standardised mean difference (SMD) 0.19, 95% CI 0.00 to 0.38), and low-certainty evidence from two studies (179 participants) suggested they may slightly improve intention to vaccinate (SMD 0.55, 95% CI 0.24 to 0.85). Low-certainty evidence found the interventions may lead to little or no change in parent attitudes or beliefs about vaccination (SMD 0.03, 95% CI -0.20 to 0.27; three studies, 292 participants), or in parents' anxiety (mean difference (MD) -1.93, 95% CI -7.27 to 3.41; one study, 90 participants). Only one study (365 participants) measured the intervention cost of a case management strategy, reporting that the estimated additional cost per fully immunised child for the intervention was approximately eight times higher than usual care (low-certainty evidence). No included studies reported outcomes associated with parents' experience of the intervention (e.g. satisfaction). AUTHORS' CONCLUSIONS There is low- to moderate-certainty evidence suggesting that face-to-face information or education may improve or slightly improve children's vaccination status, parents' knowledge, and parents' intention to vaccinate.Face-to-face interventions may be more effective in populations where lack of awareness or understanding of vaccination is identified as a barrier (e.g. where people are unaware of new or optional vaccines). The effect of the intervention in a population where concerns about vaccines or vaccine hesitancy is the primary barrier is less clear. Reliable and validated scales for measuring more complex outcomes, such as attitudes or beliefs, are necessary in order to improve comparisons of the effects across studies.

Abstract
Vaccination is one of the great achievements of the 20th century, yet persistent public-health problems include inadequate, delayed, and unstable vaccination uptake. Psychology offers three general propositions for understanding and intervening to increase uptake where vaccines are available and affordable. The first proposition is that thoughts and feelings can motivate getting vaccinated. Hundreds of studies have shown that risk beliefs and anticipated regret about infectious disease correlate reliably with getting vaccinated; low confidence in vaccine effectiveness and concern about safety correlate reliably with not getting vaccinated. We were surprised to find that few randomized trials have successfully changed what people think and feel about vaccines, and those few that succeeded were minimally effective in increasing uptake. The second proposition is that social processes can motivate getting vaccinated. Substantial research has shown that social norms are associated with vaccination, but few interventions examined whether normative messages increase vaccination uptake. Many experimental studies have relied on hypothetical scenarios to demonstrate that altruism and free riding (i.e., taking advantage of the protection provided by others) can affect intended behavior, but few randomized trials have tested strategies to change social processes to increase vaccination uptake. The third proposition is that interventions can facilitate vaccination directly by leveraging, but not trying to change, what people think and feel. These interventions are by far the most plentiful and effective in the literature. To increase vaccine uptake, these interventions build on existing favorable intentions by facilitating action (through reminders, prompts, and primes) and reducing barriers (through logistics and healthy defaults); these interventions also shape behavior (through incentives, sanctions, and requirements). Although identification of principles for changing thoughts and feelings to motivate vaccination is a work in progress, psychological principles can now inform the design of systems and policies to directly facilitate action.

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