A bar chart showing the determined preventability of pregnancy-related deaths based on a study of 1,018 pregnancy-related deaths among residents of 36 states from 2017–2019. The Maternal Mortality Review Committees determined that 84.2% of the deaths were preventable. A death is considered preventable if the committee determines that there was at least some chance of the death being averted by one or more reasonable changes to patient, community, provider, facility, and/or systems factors. Preventability was unable to be determined for 22 pregnancy-related deaths.
