Maternal Mortality Review Committees

Background

Improving the quality of maternal health care and ensuring full access to it improves health outcomes and reduces preventable pregnancy-related deaths. The United States has one of the highest rates of maternal mortality among high-income countries and wide disparities by race that have been documented since rates separated by race were first published in 1935. Currently, Indigenous and Black women are dying at two to three times the rate of White women, Asian/Pacific Islander women and Hispanic women. Investigating maternal deaths—specifically by obtaining information beyond vital statistics data—is imperative to understanding why people may die while pregnant, during labor and delivery, and in the postpartum period. 

Some states first established maternal mortality review committees (MMRCs) to investigate deaths related to pregnancy in the early 20th century, when rates were the highest on record. These jurisdictions reviewed deaths in an effort to understand why many women died in childbirth and to respond to poor medical practices and inadequate care provided by physicians. Many committees became inactive by the late 1980s, following a decline in maternal deaths for several decades. Since 2016, there has been a resurgence of interest in MMRCs because of increased attention on maternal mortality and the disparate rates of death by race, leading many states to renew or strengthen their review of pregnancy-related deaths.

Nearly all jurisdictions review “pregnancy-associated” deaths, defined by the Centers for Disease Control and Prevention (CDC) and the American College of Obstetricians and Gynecologists as the death of a woman while pregnant or within one year of the end of a pregnancy, regardless of the cause. This umbrella term includes “pregnancy-related” and “pregnancy-associated, but not related” deaths. A pregnancy-related death is one that occurs while pregnant or up to a year postpartum from any cause related to or aggravated by the pregnancy or its management. A pregnancy-associated, but not related, death is one that happens during pregnancy or within one year postpartum that is not related to the pregnancy (e.g., postpartum death in a car accident). While many MMRCs determine if a pregnancy-related death was preventable, only some are required to do so. A few MMRCs review cases of maternal morbidity, which is a physical or mental illness directly related to pregnancy or childbirth; some investigate racial disparities when reviewing cases. In some states, another body—such as an advisory committee or task force—works with the state and MMRC on addressing racial disparities in maternal health outcomes and provides recommendations.

In order to conduct comprehensive, multidisciplinary reviews, MMRC members must have the necessary tools, including relevant expertise, access to data, and the ability to confidentially investigate and review case details. MMRCs, whose membership historically was exclusively physicians, generally now include a wider representation of expertise, including midwives, doulas, pathologists, mental and behavioral health experts, representatives from Native tribes and nations, community-based organizations, and those affected by a death or near death. MMRCs are able to gather information beyond what is available through vital statistics data, including reviewing various institutional records (e.g., medical files, law enforcement reports, autopsy records) and interviewing witnesses or family members. Most review committees have legal protections in place to ensure confidentiality of data and the review process, and to shield providers from liability and potential subpoenas, which all allow for more thorough investigations.

After conducting reviews of individual pregnancy-related deaths, committees develop recommendations aimed at preventing future deaths. The MMRC shares these recommendations with a variety of stakeholders, including those who can implement system or policy changes. Stakeholders may include hospitals, health care providers, state perinatal quality collaboratives, state and local policymakers and the public.

Most states have collaborated with the CDC to standardize their maternal mortality review process, including adopting a system developed by the CDC for consistent data gathering, decision making and development of actionable recommendations.
