Comprehensive review of the evidence regarding the effectiveness of community-based primary health care in improving maternal, neonatal and child health: 4. child health findings

Implementation status, drivers and barriers to the sick children quality of care improving interventions in the Oromia region, Ethiopia: case study design

BACKGROUND

Improving quality of sick child care is the primary aim of Integrated Community Case Management services and implementation fidelity is critical to translating an evidence-based intervention to practice. A community-based complex intervention was implemented at the health posts of four agrarian regions of Ethiopia from 2017 to 2018 to improve the coverage and utilization of quality child health services. This study aimed to examine the implementation status of child health care quality improvement interventions in program areas of Oromia region, Ethiopia.

METHODS

A case study design using quantitative and qualitative research methods was conducted from September to October 2018. Implementation data were collected using observations, document reviews, and program staff interviews. Program staffs including health extension workers and their supervisors were included in surveys, and purposefully selected key informants from health posts to zonal health office level were included in the qualitative component of the research. The analysis framework was focused on the fidelity of the interventions' content, frequency, duration, and coverage, as well as the potential moderating factors of implementation using the model proposed by Carroll et al. conceptual framework for implementation fidelity.

RESULTS

Performance Review Clinical Mentoring was implemented according to the plan (every 6 months) in all of the districts and around nine in ten (88%) of the core contents were implemented. Though mentoring was provided by trained mentors, the duration of mentoring was less than the plan to fully implement all of the core activities. Overall, the mentoring program has reached 88% of health extension workers. Slightly greater than three-fourths of health extension workers have been supervised (76%) according to the plan and 80% of health posts were supplied with required iCCM medicines regularly. Staff turnover, topographical challenges, lack of transportation, competing priorities, weak support and feedback from the District health office, and security problems were frequently mentioned challenges to implementation. Whereas, the existence of continual partner support, the presence of integration and coordination of activities, and changes observed were the facilitators of implementation.

CONCLUSIONS

The implementation status of the Performance Review Clinical Mentoring Meeting was sufficient, while moderate adherence was observed in supportive supervision and supply of medicines. All of the providers were reached with sick children management training. Therefore, the implementation of community-based interventions should be aware of operational challenges in order to improve and sustain the program's performance.

How does community health feature in Global Financing Facility planning documents to support reproductive, maternal, newborn, child and adolescent health and nutrition (RMNAH-N)? insights from six francophone West African countries

BACKGROUND

Community health is key for improving Reproductive, Maternal, Newborn, Child, and Adolescent Health and Nutrition (RMNCAH-N). However, how community health supports integrated RMNCAH-N service delivery in francophone West Africa is under-researched.

OBJECTIVE

We examined how six francophone West African countries (Burkina Faso, Côte d'Ivoire, Guinea, Mali, Niger, and Senegal) support community health through the Global Financing Facility for Women, Children and Adolescents (GFF).

METHODS

We conducted a content analysis on Investment Cases and Project Appraisal Documents from selected countries, and set out the scope of the analysis and the key search terms. We applied an iterative hybrid inductive-deductive approach to identify themes for data coding and extraction. The extracted data were compared within and across countries and further grouped into meaningful categories.

RESULTS

In country documents, there is a commitment to community health, with significant attention paid to various cadres of community health workers (CHWs) who undertake a range of preventive, promotive and curative roles across RMNCAH-N spectrum. While CHWs renumeration is mentioned, it varies considerably. Most community health indicators focus on CHWs' deliverables, with few related to governance and civil registration. Challenges in implementing community health include poor leadership and governance and resource shortages resulting in low CHWs performance and service utilization. While some countries invest significantly in training CHWs, structural reforms and broader community engagement are lacking.

CONCLUSIONS

There is an opportunity to better prioritize and streamline community health interventions, including integrating them into health system planning and budgeting, to fully harness their potential to improve RMNCAH-N.

Progress towards universal health coverage and inequalities in infant mortality: an analysis of 4·1 million births from 60 low-income and middle-income countries between 2000 and 2019

BACKGROUND

Expanding universal health coverage (UHC) might not be inherently beneficial to poorer populations without the explicit targeting and prioritising of low-income populations. This study examines whether the expansion of UHC between 2000 and 2019 is associated with reduced socioeconomic inequalities in infant mortality in low-income and middle-income countries (LMICs).

METHODS

We did a retrospective analysis of birth data compiled from Demographic and Health Surveys (DHSs). We analysed all births between 2000 and 2019 from all DHSs available for this period. The primary outcome was infant mortality, defined as death within 1 year of birth. Logistic regression models with country and year fixed effects assessed associations between country-level progress to UHC (using WHO's UHC service coverage index) and infant mortality (overall and by wealth quintile), adjusting for infant-level, mother-level, and country-level variables.

FINDINGS

A total of 4 065 868 births to 1 833 011 mothers were analysed from 177 DHSs covering 60 LMICs between 2000 and 2019. A one unit increase in the UHC index was associated with a 1·2% reduction in the risk of infant death (AOR 0·988, 95% CI 0·981-0·995; absolute measure of association, 0·57 deaths per 1000 livebirths). An estimated 15·5 million infant deaths were averted between 2000 and 2019 because of increases in UHC. However, richer wealth quintiles had larger associated reductions in infant mortality from UHC (quintile 5 AOR 0·983, 95% CI 0·973-0·993) than poorer quintiles (quintile 1 0·991, 0·985-0·998). In the early stages of UHC, UHC expansion was generally beneficial to poorer populations (ie, larger reductions in infant mortality for poorer households [infant deaths per 1000 per one unit increase in UHC coverage: quintile 1 0·84 vs quintile 5 0·59]), but became less so as overall coverage increased (quintile 1 0·64 vs quintile 5 0·57).

INTERPRETATION

Since UHC expansion in LMICs appears to become less beneficial to poorer populations as coverage increases, UHC policies should be explicitly designed to ensure lower income groups continue to benefit as coverage expands.

Effective interventions for improving routine childhood immunisation in low and middle-income countries: a systematic review of systematic reviews

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.

Community health workers' quality of comprehensive care: a cross-sectional observational study across three districts in South Africa

Background

Community healthcare worker (CHW) training programs are becoming increasingly comprehensive (an expanded range of diseases). However, the CHWs that the program relies on have limited training. Since CHWs' activities occur largely during household visits, which often go unsupervised and unassessed, long-term, ongoing assessment is needed to identify gaps in CHW competency, and improve any such gaps. We observed CHWs during household visits and gave scores according to the proportion of health messages/activities provided for the health conditions encountered in households. We aimed to determine (1) messages/activities scores derived from the proportion of health messages given in the households by CHWs who provide comprehensive care in South Africa, and (2) the associated factors.

Methods

In three districts (from two provinces), we trained five fieldworkers to score the messages provided by, and activities of, 34 CHWs that we randomly selected during 376 household visits in 2018 and 2020 using a cross-sectional study designs. Multilevel models were fitted to identify factors associated with the messages/activities scores, adjusted for the clustering of observations within CHWs. The models were adjusted for fieldworkers and study facilities (n = 5, respectively) as fixed effects. CHW-related (age, education level, and phase of CHW training attended/passed) and household-related factors (household size [number of persons per household], number of conditions per household, and number of persons with a condition [hypertension, diabetes, HIV, tuberculosis TB, and cough]) were investigated.

Results

In the final model, messages/activities scores increased with each extra 5-min increase in visit duration. Messages/activities scores were lower for households with either children/babies, hypertension, diabetes, a large household size, numerous household conditions, and members with either TB or cough. Increasing household size and number of conditions, also lower the score. The messages/activities scores were not associated with any CHW characteristics, including education and training.

Conclusion

This study identifies important factors related to the messages provided by and the activities of CHWs across CHW teams. Increasing efforts are needed to ensure that CHWs who provide comprehensive care are supported given the wider range of conditions for which they provide messages/activities, especially in households with hypertension, diabetes, TB/cough, and children or babies.

Development of a growth monitoring and promotion index to improve child health in Zimbabwe

In Zimbabwe, growth monitoring and promotion as conducted by community health workers are part of the nutritional surveillance system. This study seeks to develop a new index which will combine both caregiver behaviours, attitudes and CHW growth monitoring and promotion activities. An explanatory sequential mixed method design will be conducted in three phases. Phase one will comprise a scoping literature review. The second phase will comprise a needs analysis through quantitative data collection using two surveys of community health workers and caregivers of children under five years. Thereafter, qualitative data will be collected from caregivers of children under five years. The quantitative data will be analysed using SPSS while qualitative data will be collected and analysed using Atlas-ti. Phase three will be the development phase for the growth monitoring and promotion Index. The growth monitoring and promotion Index will be used to classify the GMP performance of districts through the DHIS2 thus strengthening the quality of growth monitoring and promotion. Recommendations on the findings and the adoption of the Index will be shared with the Ministry of Health and Child Care and key stakeholders implementing maternal, newborn and child health programmes in Zimbabwe for adoption and use in growth monitoring and promotion programming.

Excess risk of subsequent infection in hospitalized children from a community cohort study in Cambodia and Madagascar

BACKGROUND

Children in low- and middle-income countries are particularly vulnerable in the months following an initial health event (IHE), with increased risk of mortality caused mostly by infectious diseases. Due to exposure to a wide range of environmental stressors, hospitalization in itself might increase child vulnerability at discharge. The goal of this study was to disentangle the role of hospitalization on the risk of subsequent infection.

METHODS

Data from a prospective, longitudinal, international, multicenter mother-and-child cohort were analysed. The main outcome assessed was the risk of subsequent infection within 3 months of initial care at hospital or primary healthcare facilities. First, risk factors for being hospitalized for the IHE (Step 1) and for having a subsequent infection (Step 2) were identified. Then, inpatients were matched with outpatients using propensity scores, considering the risk factors identified in Step 1. Finally, adjusted on the risk factors identified in Step 2, Cox regression models were performed on the matched data set to estimate the effect of hospitalization at the IHE on the risk of subsequent infection.

RESULTS

Among the 1312 children presenting an IHE, 210 (16%) had a subsequent infection, mainly lower-respiratory infections. Although hospitalization did not increase the risk of subsequent diarrhoea or unspecified sepsis, inpatients were 1.7 (95% Confidence Intervals [1.0-2.8]) times more likely to develop a subsequent lower-respiratory infection than comparable outpatients.

CONCLUSION

For the first time, our findings suggest that hospitalization might increase the risk of subsequent lower-respiratory infection adjusted on severity and symptoms at IHE. This highlights the need for robust longitudinal follow-up of at-risk children and the importance of investigating underlying mechanisms driving vulnerability to infection.

Impact of the Liberian National Community Health Assistant Program on childhood illness care in Grand Bassa County, Liberia

Liberia launched its National Community Health Assistant Program in 2016, which seeks to ensure that all people living 5 kilometers or farther from a health facility have access to trained, supplied, supervised, and paid community health workers (CHWs). This study aims to evaluate the impact of the national program following implementation in Grand Bassa County in 2018 using data from population-based surveys that included information on 1291 illness episodes. We measured before-to-after changes in care for childhood illness by qualified providers in a portion of the county that implemented in a first phase compared to those which had not yet implemented. We also assessed changes in whether children received oral rehydration therapy for diarrhea and malaria rapid diagnostic tests if they had a fever by a qualified provider (facility based or CHW). For these analyses, we used a difference-in-differences approach and adjusted for potential confounding using inverse probability of treatment weighting. We also assessed changes in the source from which care was received and examined changes by key dimensions of equity (distance from health facilities, maternal education, and household wealth). We found that care of childhood illness by a qualified provider increased by 60.3 percentage points (95%CI 44.7-76.0) more in intervention than comparison areas. Difference-in-differences for oral rehydration therapy and malaria rapid diagnostic tests were 37.6 (95%CI 19.5-55.8) and 38.5 (95%CI 19.9-57.0) percentage points, respectively. In intervention areas, care by a CHW increased from 0 to 81.6% and care from unqualified providers dropped. Increases in care by a qualified provider did not vary significantly by household wealth, remoteness, or maternal education. This evaluation found evidence that the Liberian National Community Health Assistant Program has increased access to effective care in rural Grand Bassa County. Improvements were approximately equal across three measured dimensions of marginalization.

Community health workers at the dawn of a new era: 11. CHWs leading the way to "Health for All"

BACKGROUND

This is the concluding paper of our 11-paper supplement, "Community health workers at the dawn of a new era".

METHODS

We relied on our collective experience, an extensive body of literature about community health workers (CHWs), and the other papers in this supplement to identify the most pressing challenges facing CHW programmes and approaches for strengthening CHW programmes.

RESULTS

CHWs are increasingly being recognized as a critical resource for achieving national and global health goals. These goals include achieving the health-related Sustainable Development Goals of Universal Health Coverage, ending preventable child and maternal deaths, and making a major contribution to the control of HIV, tuberculosis, malaria, and noncommunicable diseases. CHWs can also play a critical role in responding to current and future pandemics. For these reasons, we argue that CHWs are now at the dawn of a new era. While CHW programmes have long been an underfunded afterthought, they are now front and centre as the emerging foundation of health systems. Despite this increased attention, CHW programmes continue to face the same pressing challenges: inadequate financing, lack of supplies and commodities, low compensation of CHWs, and inadequate supervision. We outline approaches for strengthening CHW programmes, arguing that their enormous potential will only be realized when investment and health system support matches rhetoric. Rigorous monitoring, evaluation, and implementation research are also needed to enable CHW programmes to continuously improve their quality and effectiveness.

CONCLUSION

A marked increase in sustainable funding for CHW programmes is needed, and this will require increased domestic political support for prioritizing CHW programmes as economies grow and additional health-related funding becomes available. The paradigm shift called for here will be an important step in accelerating progress in achieving current global health goals and in reaching the goal of Health for All.

Community health workers at the dawn of a new era: 6. Recruitment, training, and continuing education

BACKGROUND

This is the sixth of our 11-paper supplement entitled "Community Health Workers at the Dawn of New Era". Expectations of community health workers (CHWs) have expanded in recent years to encompass a wider array of services to numerous subpopulations, engage communities to collaborate with and to assist health systems in responding to complex and sometimes intensive threats. In this paper, we explore a set of key considerations for training of CHWs in response to their enhanced and changing roles and provide actionable recommendations based on current evidence and case examples for health systems leaders and other stakeholders to utilize.

METHODS

We carried out a focused review of relevant literature. This review included particular attention to a 2014 book chapter on training of CHWs for large-scale programmes, a systematic review of reviews about CHWs, the 2018 WHO guideline for CHWs, and a 2020 compendium of 29 national CHW programmes. We summarized the findings of this latter work as they pertain to training. We incorporated the approach to training used by two exemplary national CHW programmes: for health extension workers in Ethiopia and shasthya shebikas in Bangladesh. Finally, we incorporated the extensive personal experiences of all the authors regarding issues in the training of CHWs.

RESULTS

The paper explores three key themes: (1) professionalism, (2) quality and performance, and (3) scaling up. Professionalism: CHW tasks are expanding. As more CHWs become professionalized and highly skilled, there will still be a need for neighbourhood-level voluntary CHWs with a limited scope of work. Quality and performance: Training approaches covering relevant content and engaging CHWs with other related cadres are key to setting CHWs up to be well prepared. Strategies that have been recently integrated into training include technological tools and provision of additional knowledge; other strategies emphasize the ongoing value of long-standing approaches such as regular home visitation. Scale-up: Scaling up entails reaching more people and/or adding more complexity and quality to a programme serving a defined population. When CHW programmes expand, many aspects of health systems and the roles of other cadres of workers will need to adapt, due to task shifting and task sharing by CHWs.

CONCLUSION

Going forward, if CHW programmes are to reach their full potential, ongoing, up-to-date, professionalized training for CHWs that is integrated with training of other cadres and that is responsive to continued changes and emerging needs will be essential. Professionalized training will require ongoing monitoring and evaluation of the quality of training, continual updating of pre-service training, and ongoing in-service training-not only for the CHWs themselves but also for those with whom CHWs work, including communities, CHW supervisors, and other cadres of health professionals. Strong leadership, adequate funding, and attention to the needs of each cadre of CHWs can make this possible.

Evidence on the effectiveness of community-based primary health care in improving HIV/AIDS outcomes for mothers and children in low- and middle-income countries: Findings from a systematic review

BACKGROUND

The effectiveness of community-based primary health care (CBPHC) interventions in low- and middle-income countries (LMICs), especially for maternal, neonatal and child health, is well established. However, there has not been a systematic review of the literature on the effectiveness of CBPHC on HIV outcomes derived from rigorous assessments of primary studies. Using peer-reviewed studies of randomized interventions or those containing a specified control group and directly measuring clinical HIV outcomes, we provide evidence for the effectiveness of CBPHC on HIV outcomes for mothers and children in low- and middle-income countries (LMICs).

METHODS

Eligibility criteria included studies assessing the effectiveness of community-based HIV interventions with or without a facility-based component, or multiple integrated projects, with outcome measures defining an aspect of HIV health status such as the utilization of prevention or health care services, nutritional status, serious morbidity (including clinical measures of HIV progression) or mortality of children aged five or younger and pregnant women. Articles published through June 3, 2020 were identified by searching four databases. The type of community-based projects implemented, the implementors, and the implementation strategies of each program were identified and the impact on HIV-related outcomes assessed.

RESULTS

The search yielded 10 537 articles; 4881 underwent title and abstract screening after removing duplicates. Of these, 117 studies qualified for full-text screening; only 22 were included in the final analysis. Most studies showed that community-based interventions improved HIV prevention and treatment outcomes compared to facility-based approaches alone. Each study had at least one statistically significant HIV-related outcome; the non-significant outcomes found in six of the 22 studies were mostly not related to HIV programming. Most interventions were implemented by community health workers; other implementers were government workers, community members, or research staff. Strategies used included peer-to-peer education, psychosocial support, training of community champions, community-based follow-up care, home-based care, and integrated care.

CONCLUSIONS

CBPHC strategies are effective in improving population-based, HIV-related health outcomes for mothers and children, especially in combination with facility-based approaches. However, there is a need to assess the scalability of such interventions and integrate them into existing health systems to assess their impact on the HIV pandemic in more routine settings.

Exploring maternal nutrition counseling provided by health professionals during antenatal care follow-up: a qualitative study in Addis Ababa, Ethiopia-2019

BACKGROUND

Nutritional awareness and practice of women during pregnancy could be determining their nutritional status, which significantly affects the outcome of pregnancy. Therefore this study aims to explore the maternal nutrition counseling provided by health professionals for pregnant women, Barriers to maternal nutrition, and major interventions.

METHODS

A descriptive study design with a qualitative method by using ground theory tradition, based on constructivist research approach and Charmaz's (2000) study design has been conducted from September-01/2019 _November-16/2019 among pregnant women who got ANC service in Addis Ababa, Ethiopia. A purposive sampling technique was used. Practical observations and in-depth interviews were conducted. The sample size adjustment has been carried out according to the information saturation obtained, and finally, 81 practical observations, In-depth interview with two center managers, nine health professionals and eleven term pregnant women has been conducted. An observational checklist and Semi-structured, open-ended questionnaires were used. Data, the environment, and methodological triangulation were carried out. A conceptual framework has been established based on the data collected about the whole process of maternal nutrition counseling during pregnancy. ATLAS TI software was utilized for information analysis.

THE RESULTS

Most participants responded that maternal nutrition counseling provided to pregnant mothers is not adequate and neglected by most stakeholders. From 81 practical observations, health professionals counseled to mothers were 10 what to feed, 4 what to limit to consume, and 5 were counseled about what to eat during pregnancy. Close to all the respondents agreed on the importance of providing nutrition counseled by the nutritionists. Most of the study participants emphasized a shortage of time as primary barriers. Institutional Barriers, Professional Barriers, Maternal Barriers, and Community Barriers were major barriers to nutrition counseling.

CONCLUSIONS

Generally, maternal nutrition counseling provided to pregnant mothers was not adequate and neglected by most stakeholders. Shortage of time due to client flow, Institutional Barriers, Professional Barriers, Maternal Barriers, and Community Barriers were major categories of maternal nutritional counseling barriers. Information update and timely preparation were recommended to health professionals.

One-arm safety intervention study on community case management of chest indrawing pneumonia in children in Nigeria - a study protocol

Current recommendations within integrated community case management (iCCM) programmes advise community health workers (CHWs) to refer cases of chest indrawing pneumonia to health facilities for treatment, but many children die due to delays or non-compliance with referral advice. Recent revision of World Health Organization (WHO) pneumonia guidelines and integrated management of childhood illness chart booklet recommend oral amoxicillin for treatment of lower chest indrawing (LCI) pneumonia on an outpatient basis. However, these guidelines did not recommend its use by CHWs as part of iCCM, due to insufficient evidence regarding safety. We present a protocol for a one-arm safety intervention study aimed at increasing access to treatment of pneumonia by training CHWs, locally referred to as Community Oriented Resource Persons (CORPs) in Nigeria. The primary objective was to assess if CORPs could safely and appropriately manage LCI pneumonia in 2-59 month old children, and refer children with danger signs. The primary outcomes were the proportion of children 2-59 months with LCI pneumonia who were managed appropriately by CORPs and the clinical treatment failure within 6 days of LCI pneumonia. Secondary outcomes included proportion of children with LCI followed up by CORPs on day 3; caregiver adherence to treatment for chest indrawing, acceptability and satisfaction of both CORP and caregivers on the mode of treatment, including caregiver adherence to treatment; and clinical relapse of pneumonia between day 7 to 14 among children whose signs of pneumonia disappeared by day 6. Approximately 308 children 2-59 months of age with LCI pneumonia would be needed for this safety intervention study.

Measuring Knowledge of Community Health Workers at the Last Mile in Liberia: Feasibility and Results of Clinical Vignette Assessments

We integrated clinical vignettes into routine programmatic supervision to assess community health worker knowledge of integrated community case management in rural Liberia. Results included higher rates of correct diagnosis and lifesaving treatment for uncomplicated disease than for more severe cases, with accurate recognition of danger signs posing a challenge.

Introduction:

Community health workers (CHWs) can provide lifesaving treatment for children in remote areas, but high-quality care is essential for effective delivery. Measuring the quality of community-based care in remote areas is logistically challenging. Clinical vignettes have been validated in facility settings as a proxy for competency. We assessed feasibility and effectiveness of clinical vignettes to measure CHW knowledge of integrated community case management (iCCM) in Liberia's national CHW program.

Methods:

We developed 3 vignettes to measure knowledge of iCCM illnesses (malaria, diarrhea, and pneumonia) in 4 main areas: assessment, diagnosis, treatment, and caregiver instructions. Trained nurse supervisors administered the vignettes to CHWs in 3 counties in rural Liberia as part of routine program supervision between January and May 2019, collected data on CHW knowledge using a standardized checklist tool, and provided feedback and coaching to CHWs in real time after vignette administration. Proportions of vignettes correctly managed, including illness classification, treatment, and referral where necessary, were calculated. We assessed feasibility, defined as the ability of clinical supervisors to administer the vignettes integrated into their routine activities once per year for each CHW, and effectiveness, defined as the ability of the vignettes to measure the primary outcomes of CHW knowledge of diagnosis and treatment including referrals.

Results:

We were able to integrate this assessment into routine supervision, facilitate real-time coaching, and collect data on iCCM knowledge among 155 CHWs through delivery of 465 vignettes. Diagnosis including severity was correct in 65%–82% of vignettes. CHWs correctly identified danger signs in 44%–50% of vignettes, correctly proposed referral to the facility in 63% of vignettes including danger signs, and chose correct lifesaving treatment in 23%–65% of vignettes. Both diagnosis and lifesaving treatment rates were highest for malaria and lowest for severe pneumonia.

Conclusion:

Administration of vignettes to assess knowledge of correct iCCM case management was feasible and effective in producing results in this setting. Proportions of correct diagnosis and lifesaving treatment varied, with high proportions for uncomplicated disease, but lower for more severe cases, with accurate recognition of danger signs posing a challenge. Future work includes validation of vignettes for use with CHWs through direct observation, strengthening supportive supervision, and program interventions to address identified knowledge gaps.

Impact of the Ananya program on reproductive, maternal, newborn and child health and nutrition in Bihar, India: early results from a quasi-experimental study

BACKGROUND

The Government of Bihar (GoB) in India, the Bill and Melinda Gates Foundation and several non-governmental organisations launched the Ananya program aimed to support the GoB to improve reproductive, maternal, newborn and child health and nutrition (RMNCHN) statewide. Here we summarise changes in indicators attained during the initial two-year pilot phase (2012-2013) of implementation in eight focus districts of approximately 28 million population, aimed to inform subsequent scale-up.

METHODS

The quasi-experimental impact evaluation included statewide household surveys at two time points during the pilot phase: January-April 2012 ("baseline") including an initial cohort of beneficiaries and January-April 2014 ("midline") with a new cohort. The two arms were: 1) eight intervention districts, and 2) a comparison arm comprised of the remaining 30 districts in Bihar where Ananya interventions were not implemented. We analysed changes in indicators across the RMNCHN continuum of care from baseline to midline in intervention and comparison districts using a difference-in-difference analysis.

RESULTS

Indicators in the two arms were similar at baseline. Overall, 40% of indicators (20 of 51) changed significantly from baseline to midline in the comparison districts unrelated to Ananya; two-thirds (n = 13) of secular indicator changes were in a direction expected to promote health. Statistically significant impact attributable to the Ananya program was found for 10% (five of 51) of RMNCHN indicators. Positive impacts were most prominent for mother's behaviours in contraceptive utilisation.

CONCLUSIONS

The Ananya program had limited impact in improving health-related outcomes during the first two-year period covered by this evaluation. The program's theories of change and action were not powered to observe statistically significant differences in RMNCHN indicators within two years, but rather aimed to help inform program improvements and scale-up. Evaluation of large-scale programs such as Ananya using theory-informed, equity-sensitive (including gender), mixed-methods approaches can help elucidate causality and better explain pathways through which supply- and demand-side interventions contribute to changes in behaviour among the actors involved in the production of population-level health outcomes. Evidence from Bihar indicates that deep structural constraints in health system organisation and delivery of interventions pose substantial limitations on behaviour change among health care providers and beneficiaries.

Does a complex intervention targeting communities, health facilities and district health managers increase the utilisation of community-based child health services? A before and after study in intervention and comparison areas of Ethiopia

INTRODUCTION

Ethiopia successfully reduced mortality in children below 5 years of age during the past few decades, but the utilisation of child health services was still low. Optimising the Health Extension Programme was a 2-year intervention in 26 districts, focusing on community engagement, capacity strengthening of primary care workers and reinforcement of district accountability of child health services. We report the intervention's effectiveness on care utilisation for common childhood illnesses.

METHODS

We included a representative sample of 5773 households with 2874 under-five children at baseline (December 2016 to February 2017) and 10 788 households and 5639 under-five children at endline surveys (December 2018 to February 2019) in intervention and comparison areas. Health facilities were also included. We assessed the effect of the intervention using difference-in-differences analyses.

RESULTS

There were 31 intervention activities; many were one-off and implemented late. In eight districts, activities were interrupted for 4 months. Care-seeking for any illness in the 2 weeks before the survey for children aged 2-59 months at baseline was 58% (95% CI 47 to 68) in intervention and 49% (95% CI 39 to 60) in comparison areas. At end-line it was 39% (95% CI 32 to 45) in intervention and 34% (95% CI 27 to 41) in comparison areas (difference-in-differences -4 percentage points, adjusted OR 0.49, 95% CI 0.12 to 1.95). The intervention neither had an effect on care-seeking among sick neonates, nor on household participation in community engagement forums, supportive supervision of primary care workers, nor on indicators of district accountability for child health services.

CONCLUSION

We found no evidence to suggest that the intervention increased the utilisation of care for sick children. The lack of effect could partly be attributed to the short implementation period of a complex intervention and implementation interruption. Future funding schemes should take into consideration that complex interventions that include behaviour change may need an extended implementation period.

How do decision-makers use evidence in community health policy and financing decisions? A qualitative study and conceptual framework in four African countries

Various investments could help countries deliver on the universal health coverage (UHC) goals set by the global community; community health is a pillar of many national strategies towards UHC. Yet despite resource mobilization towards this end, little is known about the potential costs and value of these investments, as well as how evidence on the same would be used in related decisions. This qualitative study was conducted to understand the use of evidence in policy and financing decisions for large-scale community health programmes in low- and middle-income countries. Through key informant interviews with 43 respondents in countries with community health embedded in national UHC strategies (Ethiopia, Kenya, Malawi, Mozambique) and at global institutions, we investigated evidence use in community health financing and policy decision-making, as well as evidentiary needs related to community health data for decision-making. We found that evidence use is limited at all levels, in part due to a perceived lack of high-quality, relevant evidence. This perception stems from two main areas: first, desire for local evidence that reflects the context, and second, much existing economic evidence does not deal with what decision-makers value when it comes to community health systems-i.e. coverage and (to a lesser extent) quality. Beyond the evidence gap, there is limited capacity to assess and use the evidence. Elected officials also face political challenges to disinvestment as well as structural obstacles to evidence use, including the outsized influence of donor priorities. Evaluation data must to speak to decision-maker interests and constraints more directly, alongside financiers of community health providing explicit guidance and support on the role of evidence use in decision-making, empowering national decision-makers. Improved data quality, increased relevance of evidence and capacity for evidence use can drive improved efficiency of financing and evidence-based policymaking.

Mobile clinics in humanitarian emergencies: a systematic review

BACKGROUND

Despite the widespread reliance on mobile clinics for delivering health services in humanitarian emergencies there is little empirical evidence to support their use. We report a narrative systematic review of the empirical evidence evaluating the use of mobile clinics in humanitarian settings.

METHODS

We searched MEDLINE, EMBASE, Global Health, Health Management Information Consortium, and The Cochrane Library for manuscripts published between 2000 and 2019. We also conducted a grey literature search via Global Health, Open Grey, and the WHO publication database. Empirical studies were included if they reported on at least one of the following evaluation criteria: relevance/appropriateness, connectedness, coherence, coverage, efficiency, effectiveness, and impact.

FINDINGS

Five studies met the inclusion criteria: all supported the use of mobile clinics in the particular setting under study. Three studies included controls. Two studies were assessed as good quality. The studies reported on mobile clinics providing non-communicable disease interventions, mental health services, sexual and reproductive health services, and multiple primary health care services in Afghanistan, the Democratic Republic of the Congo , Haiti, and the Occupied Palestinian Territories. Studies assessed one or more of the following evaluation domains: relevance/appropriateness, coverage, efficiency, and effectiveness. Four studies made recommendations including: i) ensure that mobile clinics are designed to complement clinic-based services; ii) improve technological tools to support patient follow-up, improve record-keeping, communication, and coordination; iii) avoid labelling services in a way that might stigmatise attendees; iv) strengthen referral to psychosocial and mental health services; v) partner with local providers to leverage resources; and vi) ensure strong coordination to optimise the continuum of care. Recommendations regarding the evaluation of mobile clinics include carrying out comparative studies of various modalities (including fixed facilities and community health workers) in order to isolate the effects of the mobile clinics. In the absence of a sound evidence base informing the use of mobile clinics in humanitarian crises, we encourage the integration of: i) WASH services, ii) nutrition services, iii) epidemic surveillance, and iv) systems to ensure the quality and safety of patient care. We recommend that future evaluations report against an established evaluation framework.

CONCLUSION

Evidence supporting the use of mobile clinics in humanitarian emergencies is limited. We encourage more studies of the use of mobile clinics in emergency settings.

Development assistance for community health workers in 114 low- and middle-income countries, 2007-2017

OBJECTIVE

To estimate the level and trend of development assistance for community health worker-related projects in low- and middle-income countries between 2007 and 2017.

METHODS

We extracted data from the Organisation for Economic Co-operation and Development's creditor reporting system on aid funding for projects to support community health workers (CHWs) in 114 countries over 2007-2017. We produced estimates for projects specifically described by relevant keywords and for projects which could include components on CHWs. We analysed the pattern of development assistance by purpose, donors, recipient regions and countries, and trends over time.

FINDINGS

Between 2007 and 2017, total development assistance targeting CHW projects was around United States dollars (US$) 5 298.02 million, accounting for 2.5% of the US$ 209 277.99 million total development assistance for health. The top three donors (Global Fund to Fight AIDS, Tuberculosis and Malaria, the government of Canada and the government of the United States of America) provided a total of US$ 4 350.08 million (82.1%) of development assistance for these projects. Sub-Saharan Africa received a total US$ 3 717.93 million, the largest per capita assistance over 11 years (US$ 0.39; total population: 9 426.25 million). Development assistance to projects that focused on infectious diseases and child and maternal health received most funds during the study period.

CONCLUSION

The share of development assistance invested in the CHW projects was small, unstable and decreasing in recent years. More research is needed on tracking government investments in CHW-related projects and assessing the impact of investments on programme effectiveness.

Proactive case detection of common childhood illnesses by community health workers: a systematic review

INTRODUCTION

Identifying design features and implementation strategies to optimise community health worker (CHW) programmes is important in the context of mixed results at scale. We systematically reviewed evidence of the effects of proactive case detection by CHWs in low-income and middle-income countries (LMICs) on mortality, morbidity and access to care for common childhood illnesses.

METHODS

Published studies were identified via electronic databases from 1978 to 2017. We included randomised and non-randomised controlled trials, controlled before-after studies and interrupted time series studies, and assessed their quality for risk of bias. We reported measures of effect as study investigators reported them, and synthesised by outcomes of mortality, disease prevalence, hospitalisation and access to treatment. We calculated risk ratios (RRs) as a principal summary measure, with CIs adjusted for cluster design effect.

RESULTS

We identified 14 studies of 11 interventions from nine LMICs that met inclusion criteria. They showed considerable diversity in intervention design and implementation, comparison, outcomes and study quality, which precluded meta-analysis. Proactive case detection may reduce infant mortality (RR: 0.52-0.94) and increase access to effective treatment (RR: 1.59-4.64) compared with conventional community-based healthcare delivery (low certainty evidence). It is uncertain whether proactive case detection reduces mortality among children under 5 years (RR: 0.04-0.80), prevalence of infectious diseases (RR: 0.06-1.02), hospitalisation (RR: 0.38-1.26) or increases access to prompt treatment (RR: 1.00-2.39) because the certainty of this evidence is very low.

CONCLUSION

Proactive case detection may provide promising benefits for child health, but evidence is insufficient to draw conclusions. More research is needed on proactive case detection with rigorous study designs that use standardised outcomes and measurement methods, and report more detail on complex intervention design and implementation.

What do Accredited Social Health Activists need to provide comprehensive care that incorporates non-communicable diseases? Findings from a qualitative study in Andhra Pradesh, India

BACKGROUND

The Indian National Program for Cardiovascular Disease, Diabetes, Cancer and Stroke (NPCDCS) was introduced to provide non-communicable disease (NCD) care through primary healthcare teams including Accredited Social Health Activists (ASHAs). Since ASHAs are being deployed to provide NCD care on top of their regular work for the first time, there is a need to understand the current capacity and challenges faced by them.

METHODS

A desktop review of NPCDCS and ASHA policy documents was conducted. This was followed by group discussions with ASHAs, in-depth interviews with their supervisors and medical officers and group discussions with community members in Guntur, Andhra Pradesh, India. The multi-stakeholder data were analysed for themes related to needs, capacity, and challenges of ASHAs in providing NCD services.

RESULTS

This study identified three key themes-first, ASHAs are unrecognised as part of the formal NPCDCS service delivery team. Second, they are overburdened, since they deliver several NPCDCS activities without receiving training or remuneration. Third, they aspire to be formally recognised as employees of the health system. However, ASHAs are enthusiastic about the services they provide and remain an essential link between the health system and the community.

CONCLUSION

ASHAs play a key role in providing comprehensive and culturally appropriate care to communities; however, they are unrecognised and overburdened and aspire to be part of the health system. ASHAs have the potential to deliver a broad range of services, if supported by the health system appropriately.

"Remarkable solutions to impossible problems": lessons for malaria from the eradication of smallpox

BACKGROUND

Malaria elimination and eventual eradication will require internationally coordinated approaches; sustained engagement from politicians, communities, and funders; efficient organizational structures; innovation and new tools; and well-managed programmes. As governments and the global malaria community seek to achieve these goals, their efforts should be informed by the substantial past experiences of other disease elimination and eradication programmes, including that of the only successful eradication programme of a human pathogen to date: smallpox.

METHODS

A review of smallpox literature was conducted to evaluate how the smallpox programme addressed seven challenges that will likely confront malaria eradication efforts, including fostering international support for the eradication undertaking, coordinating programmes and facilitating research across the world's endemic countries, securing sufficient funding, building domestic support for malaria programmes nationally, ensuring strong community support, identifying the most effective programmatic strategies, and managing national elimination programmes efficiently.

RESULTS

Review of 118 publications describing how smallpox programmes overcame these challenges suggests eradication may succeed as a collection of individual country programmes each deriving local solutions to local problems, yet with an important role for the World Health Organization and other international entities to facilitate and coordinate these efforts and encourage new innovations. Publications describing the smallpox experience suggest the importance of avoiding burdensome bureaucracy while employing flexible, problem-solving staff with both technical and operational backgrounds to overcome numerous unforeseen challenges. Smallpox's hybrid strategy of leveraging basic health services while maintaining certain separate functions to ensure visibility, clear targets, and strong management, aligns with current malaria approaches. Smallpox eradication succeeded by employing data-driven strategies that targeted resources to the places where they were most needed rather than attempting to achieve mass coverage everywhere, a potentially useful lesson for malaria programmes seeking universal coverage with available tools. Finally, lessons from smallpox programmes suggest strong engagement with the private sector and affected communities can help increase the sustainability and reach of today's malaria programmes.

CONCLUSIONS

It remains unclear whether malaria eradication is feasible, but neither was it clear whether smallpox eradication was feasible until it was achieved. To increase chances of success, malaria programmes should seek to strengthen programme management, measurement, and operations, while building flexible means of sharing experiences, tools, and financing internationally.

Community-based Malaria Screening and Treatment for Pregnant Women Receiving Standard Intermittent Preventive Treatment With Sulfadoxine-Pyrimethamine: A Multicenter (The Gambia, Burkina Faso, and Benin) Cluster-randomized Controlled Trial

Background

We investigated whether adding community scheduled malaria screening and treatment (CSST) with artemether-lumefantrine by community health workers (CHWs) to standard intermittent preventive treatment in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) would improve maternal and infant health.

Methods

In this 2-arm cluster-randomized, controlled trial, villages in Burkina Faso, The Gambia, and Benin were randomized to receive CSST plus IPTp-SP or IPTp-SP alone. CHWs in the intervention arm performed monthly CSST during pregnancy. At each contact, filter paper and blood slides were collected, and at delivery, a placental biopsy was collected. Primary and secondary endpoints were the prevalence of placental malaria, maternal anemia, maternal peripheral infection, low birth weight, antenatal clinic (ANC) attendance, and IPTp-SP coverage.

Results

Malaria infection was detected at least once for 3.8% women in The Gambia, 16.9% in Benin, and 31.6% in Burkina Faso. There was no difference between study arms in terms of placenta malaria after adjusting for birth season, parity, and IPTp-SP doses (adjusted odds ratio, 1.06 [95% confidence interval, .78-1.44]; P = .72). No difference between the study arms was found for peripheral maternal infection, anemia, and adverse pregnancy outcomes. ANC attendance was significantly higher in the intervention arm in Burkina Faso but not in The Gambia and Benin. Increasing number of IPTp-SP doses was associated with a significantly lower risk of placenta malaria, anemia at delivery, and low birth weight.

Conclusions

Adding CSST to existing IPTp-SP strategies did not reduce malaria in pregnancy. Increasing the number of IPTp-SP doses given during pregnancy is a priority.

Effectiveness of an action-oriented educational intervention in ensuring long term improvement of knowledge, attitudes and practices of community health workers in maternal and infant health: a randomized controlled study

BACKGROUND

The potential role of Community Health Workers (CHWs) in improving maternal and child health outcomes, particularly in low and middle-income countries and in disadvantaged communities, is receiving increased attention. Adequate and focused training is among the key requisites for enhancing CHWs performances and research is necessary to identify effective training methods.

METHODS

A randomized controlled study was designed to assess the effectiveness of a training course in improving knowledge, attitudes and practices (KAP) of CHWs regarding maternal and infant health. Seventy-eight CHWs belonging to Family Health Units in the city of Recife, Brazil were randomly allocated to intervention and control groups. The intervention group took part in a four-day interactive training course based on an action-oriented guide to perform home visits to pregnant women and their infants throughout pregnancy and infancy until 9 months of age. KAP in intervention group after training and after 1 year were compared to control group and to baseline.

RESULTS

Fifty-nine CHWs completed all KAP assessments (31 in intervention and 28 in control group). Baseline characteristics were similar in both groups. At 1 year from training, the intervention group had higher overall KAP score (120.65 vs. 108.19, p <  0.001) as well as knowledge (47.45 vs. 40.54, p <  0.001), practice (53.45 vs. 49.11, p <  0.001) and attitudes scores (19.74 vs. 18.81, p = 0.047) than the control group. Moreover, at 1 year from training, the intervention group maintained significant improvements in overall KAP score (120.65 vs. 106.55, p <  0.001) as well as in knowledge (45.45 vs. 42.13, p <  0.001), and practice (53.45 vs. 45.29, p <  0.001) scores with respect to baseline. In the control group, overall KAP (106.59 vs. 108.19, p = 0.345) as well as separate knowledge, attitudes and practices scores remained unchanged.

CONCLUSIONS

A four-day interactive training course on action-oriented home visits to pregnant women and infants produced a sustained improvement of CHWs' KAP and may represent a model to ensure retention of acquired competences.

Comprehensive review of the evidence regarding the effectiveness of community-based primary health care in improving maternal, neonatal and child health: 6. strategies used by effective projects

BACKGROUND

As part of our review of the evidence of the effectiveness of community-based primary health care (CBPHC) in improving maternal, neonatal and child health (MNCH), we summarize here the common delivery strategies of projects, programs and field research studies (collectively referred to as projects) that have demonstrated effectiveness in improving child mortality. Other articles in this series address specifically the effects of CBPHC on improving MNCH, while this paper explores the specific strategies used.

METHODS

We screened 12 166 published reports in PubMed of community-based approaches to improving maternal, neonatal and child health in high-mortality, resource-constrained settings from 1950-2015. A total of 700 assessments, including 148 reports from other publicly available sources (mostly unpublished evaluation reports and books) met the criteria for inclusion and were reviewed using a data extraction form. Here we identify and categorize key strategies used in project implementation.

RESULTS

Six categories of strategies for program implementation were identified, all of which required working in partnership with communities and health systems: (a) program design and evaluation, (b) community collaboration, (c) education for community-level staff, volunteers, beneficiaries and community members, (d) health systems strengthening, (e) use of community-level workers, and (f) intervention delivery. Four specific strategies for intervention delivery were identified: (a) recognition, referral, and (when possible) treatment of serious childhood illness by mothers and/or trained community agents, (b) routine systematic visitation of all homes, (c) facilitator-led participatory women's groups, and (d) health service provision at outreach sites by mobile health teams.

CONCLUSIONS

The strategies identified here provide useful starting points for program design in strengthening the effectiveness of CBPHC for improving MNCH.

Proactive community case management and child survival in periurban Mali

The majority of the world's population lives in urban areas, and regions with the highest under-five mortality rates are urbanising rapidly. This 7-year interrupted time series study measured early access to care and under-five mortality over the course of a proactive community case management (ProCCM) intervention in periurban Mali. Using a cluster-based, population-weighted sampling methodology, we conducted independent cross-sectional household surveys at baseline and at 12, 24, 36, 48, 60, 72 and 84 months later in the intervention area. The ProCCM intervention had five key components: (1) active case detection by community health workers (CHWs), (2) CHW doorstep care, (3) monthly dedicated supervision for CHWs, (4) removal of user fees and (5) primary care infrastructure improvements and staff capacity building. Under-five mortality rate was calculated using a Cox proportional hazard survival regression. We measured the percentage of children initiating effective antimalarial treatment within 24 hours of symptom onset and the percentage of children reported to be febrile within the previous 2 weeks. During the intervention, the rate of early effective antimalarial treatment of children 0-59 months more than doubled, from 14.7% in 2008 to 35.3% in 2015 (OR 3.198, P<0.0001). The prevalence of febrile illness among children under 5 years declined after 7 years of the intervention from 39.7% at baseline to 22.6% in 2015 (OR 0.448, P<0.0001). Communities where ProCCM was implemented have achieved an under-five mortality rate at or below 28/1000 for the past 6 years. In 2015, under-five mortality was 7/1000 (HR 0.039, P<0.0001). Further research is needed to elucidate the mechanisms of action and generalizability of ProCCM.

Comprehensive review of the evidence regarding the effectiveness of community-based primary health care in improving maternal, neonatal and child health: 5. equity effects for neonates and children

BACKGROUND

The degree to which investments in health programs improve the health of the most disadvantaged segments of the population-where utilization of health services and health status is often the worst-is a growing concern throughout the world. Therefore, questions about the degree to which community-based primary health care (CBPHC) can or actually does improve utilization of health services and the health status of the most disadvantaged children in a population is an important one.

METHODS

Using a database containing information about the assessment of 548 interventions, projects or programs (referred to collectively as projects) that used CBPHC to improve child health, we extracted evidence related to equity from a sub-set of 42 projects, identified through a multi-step process, that included an equity analysis. We organized our findings conceptually around a logical framework matrix.

RESULTS

Our analysis indicates that these CBPHC projects, all of which implemented child health interventions, achieved equitable effects. The vast majority (87%) of the 82 equity measurements carried out and reported for these 42 projects demonstrated "pro-equitable" or "equitable" effects, meaning that the project's equity indicator(s) improved to the same degree or more in the disadvantaged segments of the project population as in the more advantaged segments. Most (78%) of the all the measured equity effects were "pro-equitable," meaning that the equity criterion improved more in the most disadvantaged segment of the project population than in the other segments of the population.

CONCLUSIONS

Based on the observation that CBPHC projects commonly provide services that are readily accessible to the entire project population and that even often reach down to all households, such projects are inherently likely to be more equitable than projects that strengthen services only at facilities, where utilization diminishes greatly with one's distance away. The decentralization of services and attention to and tracking of metrics across all phases of project implementation with attention to the underserved, as can be done in CBPHC projects, are important for reducing inequities in countries with a high burden of child mortality. Strengthening CBPHC is a necessary strategy for reducing inequities in child health and for achieving universal coverage of essential services for children.

Comprehensive review of the evidence regarding the effectiveness of community-based primary health care in improving maternal, neonatal and child health: 8. summary and recommendations of the Expert Panel

BACKGROUND

The contributions that community-based primary health care (CBPHC) and engaging with communities as valued partners can make to the improvement of maternal, neonatal and child health (MNCH) is not widely appreciated. This unfortunate reality is one of the reasons why so few priority countries failed to achieve the health-related Millennium Development Goals by 2015. This article provides a summary of a series of articles about the effectiveness of CBPHC in improving MNCH and offers recommendations from an Expert Panel for strengthening CBPHC that were formulated in 2008 and have been updated on the basis of more recent evidence.

METHODS

An Expert Panel convened to guide the review of the effectiveness of community-based primary health care (CBPHC). The Expert Panel met in 2008 in New York City with senior UNICEF staff. In 2016, following the completion of the review, the Panel considered the review's findings and made recommendations. The review consisted of an analysis of 661 unique reports, including 583 peer-reviewed journal articles, 12 books/monographs, 4 book chapters, and 72 reports from the gray literature. The analysis consisted of 700 assessments since 39 were analyzed twice (once for an assessment of improvements in neonatal and/or child health and once for an assessment in maternal health).

RESULTS

The Expert Panel recommends that CBPHC should be a priority for strengthening health systems, accelerating progress in achieving universal health coverage, and ending preventable child and maternal deaths. The Panel also recommends that expenditures for CBPHC be monitored against expenditures for primary health care facilities and hospitals and reflect the importance of CBPHC for averting mortality. Governments, government health programs, and NGOs should develop health systems that respect and value communities as full partners and work collaboratively with them in building and strengthening CBPHC programs - through engagement with planning, implementation (including the full use of community-level workers), and evaluation. CBPHC programs need to reach every community and household in order to achieve universal coverage of key evidence-based interventions that can be implemented in the community outside of health facilities and assure that those most in need are reached.

CONCLUSIONS

Stronger CBPHC programs that foster community engagement/empowerment with the implementation of evidence-based interventions will be essential for achieving universal coverage of health services by 2030 (as called for by the Sustainable Development Goals recently adopted by the United Nations), ending preventable child and maternal deaths by 2030 (as called for by the World Health Organization, UNICEF, and many countries around the world), and eventually achieving Health for All as envisioned at the International Conference on Primary Health Care in 1978. Stronger CBPHC programs can also create entry points and synergies for expanding the coverage of family planning services as well as for accelerating progress in the detection and treatment of HIV/AIDS, tuberculosis, malaria, hypertension, and other chronic diseases. Continued strengthening of CBPHC programs based on rigorous ongoing operations research and evaluation will be required, and this evidence will be needed to guide national and international policies and programs.

Comprehensive review of the evidence regarding the effectiveness of community-based primary health care in improving maternal, neonatal and child health: 1. rationale, methods and database description

BACKGROUND

Community-based primary health care (CBPHC) is an approach used by health programs to extend preventive and curative health services beyond health facilities into communities and even down to households. Evidence of the effectiveness of CBPHC in improving maternal, neonatal and child health (MNCH) has been summarized by others, but our review gives particular attention to not only the effectiveness of specific interventions but also their delivery strategies at the community level along with their equity effects. This is the first article in a series that summarizes and analyzes the assessments of programs, projects, and research studies (referred to collectively as projects) that used CBPHC to improve MNCH in low- and middle-income countries. The review addresses the following questions: (1) What kinds of projects were implemented? (2) What were the outcomes of these projects? (3) What kinds of implementation strategies were used? (4) What are the implications of these findings?

METHODS

12 166 reports were identified through a search of articles in the National Library of Medicine database (PubMed). In addition, reports in the gray literature (available online but not published in a peer-reviewed journal) were also reviewed. Reports that describe the implementation of one or more community-based interventions or an integrated project in which an assessment of the effectiveness of the project was carried out qualified for inclusion in the review. Outcome measures that qualified for inclusion in the review were population-based indicators that defined some aspect of health status: changes in population coverage of evidence-based interventions or changes in serious morbidity, in nutritional status, or in mortality.

RESULTS

700 assessments qualified for inclusion in the review. Two independent reviewers completed a data extraction form for each assessment. A third reviewer compared the two data extraction forms and resolved any differences. The maternal interventions assessed concerned education about warning signs of pregnancy and safe delivery; promotion and/or provision of antenatal care; promotion and/or provision of safe delivery by a trained birth attendant, screening and treatment for HIV infection and other maternal infections; family planning, and; HIV prevention and treatment. The neonatal and child health interventions that were assessed concerned promotion or provision of good nutrition and immunizations; promotion of healthy household behaviors and appropriate utilization of health services, diagnosis and treatment of acute neonatal and child illness; and provision and/or promotion of safe water, sanitation and hygiene. Two-thirds of assessments (63.0%) were for projects implementing three or fewer interventions in relatively small populations for relatively brief periods; half of the assessments involved fewer than 5000 women or children, and 62.9% of the assessments were for projects lasting less than 3 years. One-quarter (26.6%) of the projects were from three countries in South Asia: India, Bangladesh and Nepal. The number of reports has grown markedly during the past decade. A small number of funders supported most of the assessments, led by the United States Agency for International Development. The reviewers judged the methodology for 90% of the assessments to be adequate.

CONCLUSIONS

The evidence regarding the effectiveness of community-based interventions to improve the health of mothers, neonates, and children younger than 5 years of age is growing rapidly. The database created for this review serves as the basis for a series of articles that follow this one on the effectiveness of CBPHC in improving MNCH published in the Journal of Global Health. These findings, together with recommendations provided by an Expert Panel which has guided this review, that are included as the last paper in this series, will help to provide the rationale for building stronger community-based platforms for delivering evidence-based interventions in high-mortality, resource-constrained settings.

Comprehensive review of the evidence regarding the effectiveness of community-based primary health care in improving maternal, neonatal and child health: 2. maternal health findings

BACKGROUND

We summarize the findings of assessments of projects, programs, and research studies (collectively referred to as projects) included in a larger review of the effectiveness of community-based primary health care (CBPHC) in improving maternal, neonatal and child health (MNCH). Findings on neonatal and child health are reported elsewhere in this series.

METHODS

We searched PUBMED and other databases through December 2015, and included assessments that underwent data extraction. Data were analyzed to identify themes in interventions implemented, health outcomes, and strategies used in implementation.

RESULTS

152 assessments met inclusion criteria. The majority of assessments were set in rural communities. 72% of assessments included 1-10 specific interventions aimed at improving maternal health. A total of 1298 discrete interventions were assessed. Outcome measures were grouped into five main categories: maternal mortality (19% of assessments); maternal morbidity (21%); antenatal care attendance (50%); attended delivery (66%) and facility delivery (69%), with many assessments reporting results on multiple indicators. 15 assessments reported maternal mortality as a primary outcome, and of the seven that performed statistical testing, six reported significant decreases. Seven assessments measured changes in maternal morbidity: postpartum hemorrhage, malaria or eclampsia. Of those, six reported significant decreases and one did not find a significant effect. Assessments of community-based interventions on antenatal care attendance, attended delivery and facility-based deliveries all showed a positive impact. The community-based strategies used to achieve these results often involved community collaboration, home visits, formation of participatory women's groups, and provision of services by outreach teams from peripheral health facilities.

CONCLUSIONS

This comprehensive and systematic review provides evidence of the effectiveness of CBPHC in improving key indicators of maternal morbidity and mortality. Most projects combined community- and facility-based approaches, emphasizing potential added benefits from such holistic approaches. Community-based interventions will be an important component of a comprehensive approach to accelerate improvements in maternal health and to end preventable maternal deaths by 2030.
