Impact of public health programs on maternal and child health services and health outcomes in India: A systematic review.

Background: In the last two decades, India's central and many state governments launched several public health programs with the goal of improving maternal and child health outcomes. Many individual studies assessed the impact of these programs; however, they focused on select health programs and few specific outcomes.
Objectives and Methods: This paper summarizes the literature, published during 2000-2019, investigating the impacts of public health programs on both the uptake of maternal and child health services and the related-health outcomes in India. We followed PRISMA guidelines of systematic review, and carried out a narrative synthesis of the study findings.
Findings and Conclusion: We found 66 relevant studies covering 11 health programs across India. Most studies had applied non-experimental study designs (n = 50), with few applying experimental (n = 1) and quasi-experimental (n = 15) designs. Most studies (n = 64) assessed the impact on the intermediate outcomes of the uptake of various health services rather on the long-term outcomes of improvement in health. Overall we found studies reporting positive impacts, however, we could not find any strong consensus emerging from these studies about the impact, partly due to differences in: outcome indicators; study designs; study population; data sets. Several studies also reported considerable beneficial impacts among low socioeconomic population groups. However, given that the outreach of the public health programs have been low across the country and population groups, we found that broader objectives of health programs remained unassessed: most studies assessed the impact on who actually participated in the program (average treatment effect on-the-treated) rather on the target population (intent-to-treat effect). Furthermore, there was dearth of research on the impacts of the state-level programs. Future research need to assess the impact of the programs on health outcomes, and on quality adjusted measures of maternal and child health services and its continuum of care.
