Health insurance coverage and access to child and maternal health services in West Africa: a systematic scoping review

Background According to the United Nations, the third Sustainable Development Goal, 'Ensure Healthy Lives and Promote Well-Being at All Ages', set numerous targets on child and maternal health. Universal health insurance is broadly seen as a solution to fulfil these targets. West Africa is known to have the most severe maternal mortality and under-five mortality rates in the world. This review seeks to understand whether health insurance provides increased access to services for mothers and children in this region. Methods The protocol for this review is registered in the International Prospective Register of Systematic Reviews database (CRD42020203859). A search was conducted in the MEDLINE Complete, Embase, CINAHL Complete and Global Health databases. Eligible studies were from West African countries. The population of interest was mothers and children and the outcome of interest was the impact of health insurance on access to services. Data were extracted using a standardized form. The primary outcome was the impact of health insurance on the rate of utilization and access to services. The Joanna Briggs Institute Critical Appraisal Tool was used for methodological assessment. Results Following screening, we retained 49 studies representing 51 study settings. In most study settings, health insurance increased access to child and maternal health services. Other determinants of access were socio-economic factors such as wealth and education. Conclusions Our findings suggest that health insurance may be a viable long-term strategy to alleviate West Africa's burden of high maternal and child mortality rates. An equity lens must guide future policy developments and significant research is needed to determine how to provide access reliably and sustainably to services for mothers and children in the near and long term.
