A simple provider-based educational intervention to boost infant immunization rates: a controlled trial

Systematic review on reducing missed opportunities for vaccinations in Latin America

Objectives

To estimate the prevalence of missed opportunities for vaccination (MOV) in Latin America and the effect of interventions targeting health systems, health workers, patients, and communities on MOV.

Methods

Searches were conducted in MEDLINE, EMBASE, CINAHL, and LILACS electronic databases and relevant organizations were contacted, including the Pan American Health Organization (PAHO), to identify studies meeting eligibility criteria. A pair of reviewers identified 27 randomized and non-randomized studies quantifying the effectiveness of any intervention for reducing MOV and 5 studies assessing the rate of MOV in Latin America. Results are reported narratively when criteria to pool results were not met, and the certainty of this evidence was assessed using the GRADE approach.

Results

Evidence suggests the rate of MOV in Latin America ranged from 5% to 37% with a pooled estimate of 17% (95% CI [9, 32]) (low certainty) and that monetary incentives to healthcare teams, training for healthcare teams on how to communicate with patients, and educational interventions for caregivers probably reduce MOV (moderate to very low certainty).

Conclusions

There is insufficient evidence supporting the implementation of any intervention as policy based only on the potential reduction of MOV without considering several factors, including costs, feasibility, acceptability, and equity.

Roles of the Maternal and Child Health Handbook and Other Home-Based Records on Newborn and Child Health: A Systematic Review

Home-based records are paper or electronic records retained and used by mothers or caregivers to document the health services received for maternal, newborn, and child health. Little has been studied about the roles of these records on newborn and child health outcomes. Hence, we collated and summarized evidence concerning the roles of home-based records in improving newborn and child health. We conducted a systematic search in several databases: MEDLINE, Web of Science, CINAHL, PsycINFO, PsycARTICLES, Academic Search Complete, SocINDEX, CENTRAL, DARE, NHS EED, HTA, J-STAGE, Ichushi, and gray literature. We included original research articles of all study designs published in English or Japanese until January 2020. Owing to heterogeneity across the outcomes of included studies, we conducted a narrative synthesis. We included 55 studies (23 in Japanese) among 14,017 identified articles. We identified the following roles of home-based records on newborn and child health: promoted newborn/childcare seeking, improved knowledge and practices of newborn/childcare, encouraged home care for childhood illnesses, reduced child mortality and morbidity, and facilitated continuum of care. We observed a mixed effect on age-appropriate immunization (e.g., DTP3 completion) and no effect on the practice of immediate breastfeeding and prevention of perinatal mortality and morbidity. The findings highlighted the effectiveness and usefulness of home-based records to improve newborn and child health outcomes. However, only a few studies were available for each outcome category, limiting the certainty of evidence provided in this review. Therefore, we recommend further studies to explore the benefits of home-based records on improving newborn and child health.

Community-based maternal and newborn educational care packages for improving neonatal health and survival in low- and middle-income countries

BACKGROUND

In low- and middle-income countries (LMICs), health services are under-utilised, and several studies have reported improvements in neonatal outcomes following health education imparted to mothers in homes, at health units, or in hospitals. However, evaluating health educational strategy to deliver newborn care, such as one-to-one counselling or group counselling via peer or support groups, or delivered by health professionals, requires rigorous assessment of methodological design and quality, as well as assessment of cost-effectiveness, affordability, sustainability, and reproducibility in diverse health systems.

OBJECTIVES

To compare a community health educational strategy versus no strategy or the existing approach to health education on maternal and newborn care in LMICs, as imparted to mothers or their family members specifically in community settings during the antenatal and/or postnatal period, in terms of effectiveness for improving neonatal health and survival (i.e. neonatal mortality, neonatal morbidity, access to health care, and cost).

SEARCH METHODS

We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 4), in the Cochrane Library, MEDLINE via PubMed (1966 to 2 May 2017), Embase (1980 to 2 May 2017), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 2 May 2017). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.

SELECTION CRITERIA

Community-based randomised controlled, cluster-randomised, or quasi-randomised controlled trials.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted the data. We assessed the quality of evidence using the GRADE method and prepared 'Summary of findings' tables.

MAIN RESULTS

We included in this review 33 original trials (reported in 62 separate articles), which were conducted across Africa and Central and South America, with most reported from Asia, specifically India, Pakistan, and Bangladesh. Of the 33 community educational interventions provided, 16 included family members in educational counselling, most frequently the mother-in-law or the expectant father. Most studies (n = 14) required one-to-one counselling between a healthcare worker and a mother, and 12 interventions involved group counselling for mothers and occasionally family members; the remaining seven incorporated components of both counselling methods. Our analyses show that community health educational interventions had a significant impact on reducing overall neonatal mortality (risk ratio (RR) 0.87, 95% confidence interval (CI) 0.78 to 0.96; random-effects model; 26 studies; n = 553,111; I² = 88%; very low-quality evidence), early neonatal mortality (RR 0.74, 95% CI 0.66 to 0.84; random-effects model; 15 studies that included 3 subsets from 3 studies; n = 321,588; I² = 86%; very low-quality evidence), late neonatal mortality (RR 0.54, 95% CI 0.40 to 0.74; random-effects model; 11 studies; n = 186,643; I² = 88%; very low-quality evidence), and perinatal mortality (RR 0.83, 95% CI 0.75 to 0.91; random-effects model; 15 studies; n = 262,613; I² = 81%; very low-quality evidence). Moreover, community health educational interventions increased utilisation of any antenatal care (RR 1.16, 95% CI 1.11 to 1.22; random-effects model; 18 studies; n = 307,528; I² = 96%) and initiation of breastfeeding (RR 1.56, 95% CI 1.37 to 1.77; random-effects model; 19 studies; n = 126,375; I² = 99%). In contrast, community health educational interventions were found to have a non-significant impact on use of modern contraceptives (RR 1.10, 95% CI 0.86 to 1.41; random-effects model; 3 studies; n = 22,237; I² = 80%); presence of skilled birth attendance at birth (RR 1.09, 95% CI 0.94 to 1.25; random-effects model; 10 studies; n = 117,870; I² = 97%); utilisation of clean delivery kits (RR 4.44, 95% CI 0.71 to 27.76; random-effects model; 2 studies; n = 17,087; I² = 98%); and care-seeking (RR 1.11, 95% CI 0.97 to 1.27; random-effects model; 7 studies; n = 46,154; I² = 93%). Cost-effectiveness analysis conducted in seven studies demonstrated that the cost-effectiveness for intervention packages ranged between USD 910 and USD 11,975 for newborn lives saved and newborn deaths averted. For averted disability-adjusted life-year, costs ranged from USD 79 to USD 146, depending on the intervention strategy; for cost per year of lost lives averted, the most effective strategy was peer counsellors, and the cost was USD 33.

AUTHORS' CONCLUSIONS

This review offers encouraging evidence on the value of integrating packages of interventions with educational components delivered by a range of community workers in group settings in LMICs, with groups consisting of mothers, and additional education for family members, for improved neonatal survival, especially early and late neonatal survival.

A systematic review of strategies for reducing missed opportunities for vaccination

BACKGROUND

Missed opportunities for vaccination (MOVs) occur when persons eligible for vaccination visit a health facility and do not get the vaccines they need. We conducted a systematic review to assess effects of interventions for reducing MOVs.

METHODS

We searched PubMed, Scopus, and the Cochrane Central Register of Controlled Trials in April 2017. Three authors independently screened search outputs, reviewed potentially eligible papers, assessed risk of bias, and extracted data; resolving disagreements by consensus. We expressed study results as risk ratios (RR) with 95% confidence intervals (CI) and assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool.

RESULTS

Six studies (five trials and one cohort study) met our inclusion criteria, all conducted in the United States of America. All six studies had various limitations and were classified as having a high risk of bias. We found moderate certainty evidence that the following interventions probably improve vaccination coverage: patient education (RR 1.92, 95% CI 1.38-2.68), patient tracking using community health workers (RR 1.18, 95% CI 1.11-1.25), and patient tracking and provider prompts (RR 1.24, 95% CI 1.18-1.31). In addition, we found low certainty evidence that concurrent interventions targeting health-facility (education, prompts, and audit and feedback) and family settings (phone calls) may increase vaccination coverage (RR 1.25, 95% CI 1.08-1.46).

CONCLUSIONS

The currently available evidence suggests that patient education, patient tracking, outreach sessions, and provider prompts reduce missed opportunities for vaccination and improve vaccination coverage. Rigorous studies are required to confirm these findings and increase the certainty of the current evidence base. WHO is currently coordinating efforts to generate such evidence, especially from low-income and middle-income countries, and it is likely that the data will be available in the next few years.

Interventions to increase pediatric vaccine uptake: An overview of recent findings

Although much is known about factors contributing to variation in pediatric immunization uptake, there is a need for synthesis of effective vaccine promotion strategies. With growing public health concern on how to best sustain high pediatric immunization rates, and improve where the rates are suboptimal, this review offers evidence gathered from several studies on the achievement of these goals. We identified and analyzed reported findings on childhood (primarily ≤ 7 years) immunization outcomes from tested intervention strategies that focused on parents, guardians, and caregivers, as well as providers, clinics/practices, and communities. The findings suggest that targeted and tailored interventions offer substantial possibilities, especially in a combined manner. We describe promising intervention models that have been operationalized with success and provide evidence for scalability across contexts. Moreover, they are sensitive to parents' and providers' needs, are feasibly integrated in daily clinical practice, and account for broader community concerns and issues.

Parental reminder, recall and educational interventions to improve early childhood immunisation uptake: A systematic review and meta-analysis

Vaccination is one of the most effective ways of reducing childhood mortality. Despite global uptake of childhood vaccinations increasing, rates remain sub-optimal, meaning that vaccine-preventable diseases still pose a public health risk. A range of interventions to promote vaccine uptake have been developed, although this range has not specifically been reviewed in early childhood. We conducted a systematic review and meta-analysis of parental interventions to improve early childhood (0-5 years) vaccine uptake. Twenty-eight controlled studies contributed to six separate meta-analyses evaluating aspects of parental reminders and education. All interventions were to some extent effective, although findings were generally heterogeneous and random effects models were estimated. Receiving both postal and telephone reminders was the most effective reminder-based intervention (RD=0.1132; 95% CI=0.033-0.193). Sub-group analyses suggested that educational interventions were more effective in low- and middle-income countries (RD=0.13; 95% CI=0.05-0.22) and when conducted through discussion (RD=0.12; 95% CI=0.02-0.21). Current evidence most supports the use of postal reminders as part of the standard management of childhood immunisations. Parents at high risk of non-compliance may benefit from recall strategies and/or discussion-based forums, however further research is needed to assess the appropriateness of these strategies.

Frequent vaccination missed opportunities at primary care encounters contribute to underimmunization

OBJECTIVE

To examine missed opportunities to administer an eligible vaccination (MOs) and their contribution to underimmunization in contemporary pediatric practices.

STUDY DESIGN

This study was a retrospective analysis from 42 diverse pediatric practices located throughout the US. Medical records of 50 randomly selected children 3-18 months of age per practice were reviewed in Spring 2013. Immunization status for age and MOs were assessed as of each encounter and as of March 1, 2013.

RESULTS

Of 2076 eligible patients, 72.7% (95% CI 67.6-77.9) were up-to-date with receipt of standard vaccines. Most children (82.4%; 95% CI 78.3-85.9) had at least 1 MO, and 37.8% (95% CI 30.0-46.2) had at least one MO to administer an overdue vaccination. After adjustment, risk of underimmunization was 3.5 times greater for patients who had ever experienced an MO for an overdue vaccination compared with those who had not (adjusted relative risk = 3.5; 95% CI 2.8-4.3). If all age-appropriate vaccinations had been administered at the last recorded encounter, 45.5% (95% CI 36.8-54.5) of the underimmunized patients would have been up to date at the time of assessment.

CONCLUSION

MOs were common and contributed substantially to underimmunization in this contemporary sample of diverse primary care practice settings.

Addressing heterogeneous parental concerns about vaccination with a multiple-source model: a parent and educator perspective

Previous models of vaccine education have not addressed differences in levels and motives of vaccine concerns in parents. These differences may require changes in education approaches based on type of parental concern. Addressing vaccine concerns will require a multi-modal approach involving more than just a pediatrician or primary health care provider, as well as more than one educational approach.

A systematic review of interventions for reducing parental vaccine refusal and vaccine hesitancy

Unvaccinated individuals pose a public health threat to communities. Research has identified many factors associated with parental vaccine refusal and hesitancy toward childhood and adolescent immunizations. However, data on the effectiveness of interventions to address parental refusal are limited. We conducted a systematic review of four online databases to identify interventional studies. We used criteria recommended by the WHO's Strategic Advisory Group of Experts on immunization (SAGE) for the quality assessment of studies. Intervention categories and outcomes were evaluated for each body of evidence and confidence in overall estimates of effect was determined. There is limited evidence to guide implementation of effective strategies to deal with the emerging threat of parental vaccine refusal. There is a need for appropriately designed, executed and evaluated intervention studies to address this gap in knowledge.

Face to face interventions for informing or educating parents about early childhood vaccination

BACKGROUND

Childhood vaccination (also described as immunisation) is an important and effective way to reduce childhood illness and death. However, there are many children who do not receive the recommended vaccines because their parents do not know why vaccination is important, do not understand how, where or when to get their children vaccinated, disagree with vaccination as a public health measure, or have concerns about vaccine safety.Face to face interventions to inform or educate parents about routine childhood vaccination may improve vaccination rates and parental knowledge or understanding of vaccination. Such interventions may describe or explain the practical and logistical factors associated with vaccination, and enable parents to understand the meaning and relevance of vaccination for their family or community.

OBJECTIVES

To assess the effects of face to face interventions for informing or educating parents about early childhood vaccination on immunisation uptake and parental knowledge.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 7); MEDLINE (OvidSP) (1946 to July 2012); EMBASE + Embase Classic (OvidSP) (1947 to July 2012); CINAHL (EbscoHOST) (1981 to July 2012); PsycINFO (OvidSP) (1806 to July 2012); Global Health (CAB) (1910 to July 2012); Global Health Library (WHO) (searched July 2012); Google Scholar (searched September 2012), ISI Web of Science (searched September 2012) and reference lists of relevant articles. We searched for ongoing trials in The International Clinical Trials Registry Platform (ICTRP) (searched August 2012) and for grey literature in The Grey Literature Report and OpenGrey (searched August 2012). We also contacted authors of included studies and experts in the field. There were no language or date restrictions.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and cluster RCTs evaluating the effects of face to face interventions delivered to individual parents or groups of parents to inform or educate about early childhood vaccination, compared with control or with another face to face intervention. Early childhood vaccines are all recommended routine childhood vaccines outlined by the World Health Organization, with the exception of human papillomavirus vaccine (HPV) which is delivered to adolescents.

DATA COLLECTION AND ANALYSIS

Two authors independently reviewed database search results for inclusion. Grey literature searches were conducted and reviewed by a single author. Two authors independently extracted data and assessed the risk of bias of included studies. We contacted study authors for additional information.

MAIN RESULTS

We included six RCTs and one cluster RCT involving a total of 2978 participants. Three studies were conducted in low- or middle-income countries and four were conducted in high-income countries. The cluster RCT did not contribute usable data to the review. The interventions comprised a mix of single-session and multi-session strategies. The quality of the evidence for each outcome was low to very low and the studies were at moderate risk of bias overall. All these trials compared face to face interventions directed to individual parents with control.The three studies assessing the effect of a single-session intervention on immunisation status could not be pooled due to high heterogeneity. The overall result is uncertain because the individual study results ranged from no evidence of effect to a significant increase in immunisation.Two studies assessed the effect of a multi-session intervention on immunisation status. These studies were also not pooled due to heterogeneity and the result was very uncertain, ranging from a non-significant decrease in immunisation to no evidence of effect.The two studies assessing the effect of a face to face intervention on knowledge or understanding of vaccination were very uncertain and were not pooled as data from one study were skewed. However, neither study showed evidence of an effect on knowledge scores in the intervention group. Only one study measured the cost of a case management intervention. The estimated additional cost per fully immunised child for the intervention was approximately eight times higher than usual care.The review also considered the following secondary outcomes: intention to vaccinate child, parent experience of intervention, and adverse effects. No adverse effects related to the intervention were measured by any of the included studies, and there were no data on the other outcomes of interest.

AUTHORS' CONCLUSIONS

The limited evidence available is low quality and suggests that face to face interventions to inform or educate parents about childhood vaccination have little to no impact on immunisation status, or knowledge or understanding of vaccination. There is insufficient evidence to comment on the cost of implementing the intervention, parent intention to vaccinate, parent experience of the intervention, or adverse effects. Given the apparently limited effect of such interventions, it may be feasible and appropriate to incorporate communication about vaccination into a healthcare encounter, rather than conduct it as a separate activity.

Primary care strategies to improve childhood immunisation uptake in developed countries: systematic review

Objectives

To conduct a systematic review of strategies to optimize immunisation uptake within preschool children in developed countries.

Design

Systematic review.

Setting

Developed countries

Participants

Preschool children who were due, or overdue, one or more of their routine primary immunisations.

Main outcome measures

Increase in the proportion of the target population up to date with standard recommended universal vaccinations.

Results

Forty-six studies were included for analysis, published between 1980 and 2009. Twenty-six studies were randomized controlled trials, 11 were before and after trials, and nine were controlled intervention trials. Parental reminders showed a statistically significant increase in immunisation rates in 34% of included intervention arms. These effects were reported with both generic and specific reminders and with all methods of reminders and recall. Strategies aimed at immunisation providers were also shown to improve immunisation rates with a median change in immunisation rates of 7% when reminders were used, 8% when educational programmes were used and 19% when feedback programmes were used.

Conclusion

General practitioners are uniquely positioned to influence parental decisions on childhood immunisation. A variety of strategies studied in primary care settings have been shown to improve immunisation rates, including parental and healthcare provider reminders.

A randomised controlled trial of an educational intervention for depression among Asian women in primary care in the United Kingdom

OBJECTIVE

To determine the effect of patient education on patient perspectives and outcome of depression in a sample of Asian women in primary care.

DESIGN

A randomised, clinical trial of "patient education" versus "usual care".

SETTING

A general practice in London, which has a high proportion of Asians.

SUBJECTS

Seventy patients with psychiatric morbidity (a score of 3 or more on the General Health Questionnaire 12) were recruited for the trial.

OUTCOME MEASURES

Patient's explanatory models of illness (the patient's perspective on depression; recognition of depression as illness and recommend a medical intervention for this condition) and psychiatric morbidity at follow-up after two months were the primary outcome measures.

RESULTS

One hundred and fifty-five women of Asian decent were contacted. One hundred and forty-eight (95.5%) agreed to take part in the study. Seventy (47.3%) were classed as cases of common mental disorder using the General Health Questionnaire 12. Thirty-five were randomly allocated to receive education about the nature, causes, prevalence and treatment of depression, 35 did not receive such information. There were no statistical differences between the two groups on baseline characteristics. Sixty-six (94.3%) subjects were followed up at two months. An intention to treat analysis showed that there was no difference in explanatory model measures between the two groups at the end of the study. However, more patients who received education were no longer cases (a score of 2 or less on the GHQ) (15/35; 42.9%) compared to controls (7/35; 20%) (p < 0.05) as did those with lower GHQ scores at entry (p < 0.03). Receipt of educational intervention (OR 3.4; 95% CI 1.01, 11.5) and lower GHQ scores at entry (OR 7.1; 95% CI 1.05, 30.2) remained significantly associated with recovery after adjusting for baseline variables using logistic regression.

CONCLUSIONS

Patients with common mental disorders, especially those with milder forms of the condition, who received the educational material had a higher recovery rate than patients who do not receive such education. The mechanism for this improvement was unclear, not being reflected in patient's apparent understanding of depression nor explained by change in general practitioner's response. The results of this study need to be replicated.
