Preventability review of severe maternal morbidity.

Multidisciplinary external anonymized review of SMM showed that over a third of cases were potentially preventable, being due to substandard provider care with increased preventability rates for racial/ethnic minority women. Monitoring country rates of SMM and implementing case reviews to assess potential preventability are appropriate quality improvement measures and external review of anonymized cases may reduce racial profiling to inform unbiased appropriate interventions and resource allocation to help prevent these severe events.
