This series of papers focuses on a quality of care framework for maternal health, and systematically reviews the evidence of interventions aimed at improving care at the community-, district- and factility-levels. While the systematic reviews highlight the effectiveness of specific quality improvement efforts on maternal and newborn health, it also illlustrates the dearth of evidence on community-, district- and facility-level interventions, particulary for issues specific to quality of maternal health care and maternal newborn health outcomes. Further evidence is now needed to evaluate the best possible combination of the strategies. Governments, stakeholders and donors need to work together to form these policies and develop models of health care to suit the needs of their own population.
