Maternal Mortality Review Committees (MMRCs) are multi-disciplinary committees that convene at the state or local level to comprehensively review deaths of women during or within a year of pregnancy. MMRCs have access to clinical and non-clinical information (e.g., vital records, medical records, social service records) to more fully understand the circumstances surrounding each death, and to develop recommendations for action to prevent similar deaths in the future.

A total of 14 MMRCs voluntarily shared 2008-2017 data with CDC through the Maternal Mortality Review Information Application (MMRIA). Among 1,347 deaths to women during or within a year of pregnancy, a pregnancy-relatedness determination was made for 1,260 (93.5%). Among these, 454 (36.0%) were determined by the 14 MMRCs to be pregnancy-related.
