Identifying delays impacting maternal and perinatal deaths using a facility-based death audit review system integrated with community engagement: a mixed methods study

The four delays model identified patterns of preventable factors contributing to maternal and perinatal deaths across household and health system levels. Health systems need to invest in women's access to, and the availability of, healthcare facilities both during and after pregnancy. Scaling up and implementing audit review systems with learning feedback loops is key to systematically identifying and contributing to addressing preventable delays in resource constrained settings, particularly when comprehensive national-level mortality data are lacking.
