Demand-side financing measures to increase maternal health service utilisation and improve health outcomes: a systematic review of evidence from low- and middle-income countries

Background In many countries financing for health services has traditionally been disbursed directly from governmental and non-governmental funding agencies to providers of services: the ‘supply-side’ of healthcare markets. Demand-side financing offers a supplementary model in which some funds are instead channelled through, or to, prospective users. In this review we considered evidence on five forms of demand-side financing that have been used to promote maternal health in developing countries:   • unconditional cash transfers • conditional cash transfers • short-term cash payments to offset the cost of accessing maternal health services • vouchers for maternal health services • vouchers for ‘merit’ goods that promote maternal health. Objectives The overall review objective was to assess the effects of demand-side financing interventions on maternal health service utilisation and on maternal health outcomes in low- and middle-income countries. Broader effects on perinatal and infant health, the situation of underprivileged women and the health care system were also assessed. Inclusion criteria Types of participants This review considered poor, rural or socially excluded women of all ages who were either pregnant or within 42 days of the conclusion of pregnancy, the limit for postnatal care as defined by the World Health Organization. The review also considered the providers of services. Types of intervention(s)/phenomena of interest. The intervention of interest was any programme that incorporated demand-side financing as a mechanism to increase the consumption of goods and services that could impact on maternal health outcomes. This included the direct consumption of maternal health care goods and services as well as related ‘merit goods’ such as improved nutrition. We included systems in which potential users of maternal health services are financially empowered to make restricted decisions on buying maternal health-related goods or services – sometimes known as consumer-led demand-side financing. We also included programmes that provided unconditional cash benefits to pregnant women (for example in the form of maternity allowances), or to families with children under five years of age where there was evidence concerning maternal health outcomes. Types of studies We aimed to include quantitative studies (experimental, observational and descriptive), qualitative studies (including designs based on phenomenology, grounded theory, ethnography, action research and feminist research), and economic studies (cost-effectiveness, cost-utility and costs studies). Search strategy The Joanna Briggs Institute methodology for mixed-method systematic reviews was adopted. A three-step systematic search strategy was used to: 1) identify key terms, 2) search bibliographic databases and 3) retrieve additional publications from reference lists and sources of grey literature. Data Collection Data were extracted from papers included in the review using the standardised data extraction tools for quantitative, qualitative and economic data from the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information. Data Synthesis The quantitative and economic findings are presented in narrative form. Qualitative research findings were pooled using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. This involved the aggregation or synthesis of findings to generate a set of statements that represent that aggregation, through assembling the findings (Level 1 findings), and categorising these findings on the basis of similarity in meaning (Level 2 findings). These categories were then subjected to a meta-synthesis in order to produce a single comprehensive set of synthesised findings (Level 3 findings) that can be used as a basis for evidence-based practice or policy. Conclusions Seventy-two studies were included in the review. Drawing on work from several continents, many of the included studies were reports and evaluations for relevant government or funding agencies and represented important lesson-learning about implementation issues. However, fewer than half were published in peer reviewed journals and TRUNCATED AT 600 WORDS
