Building an effective coverage cascade for antenatal care: linking of household survey and health facility assessment data in eight low- and middle-income countries.

Background: Substantial gaps exist between pregnant women's contact with health facilities and the quality of care they receive (effective coverage) in low- and middle-income countries (LMICs). An effective coverage cascade is a useful analytical approach to uncover gaps due to poor facility service readiness and quality of care. We estimated readiness-adjusted antenatal care (ANC) coverage and built an effective coverage cascade in countries with available data.
