Comparing Two Review Processes for Determination of Preventability of Maternal Mortality in Illinois.

Abstract

To compare the results of two maternal death review processes conducted from 2002 to 2012 by Illinois regionalized perinatal centers with those conducted by the Illinois Department of Public Health's (IDPH's) statewide multidisciplinary external Maternal Mortality Review Committee (MMRC). This is a retrospective record review linking MMRC case assessment forms to the IDPH's Maternal Mortality Review Form database to compare causes of death and potential preventability as determined by both review processes. MMRC records for 76 maternal death reviews were linked to the IDPH maternal mortality review form database. Most deaths reviewed by the statewide MMRC were due to pregnancy-related causes. The statewide MMRC differed from the regional perinatal centers on cause of death in 55.3% (n = 42) of cases and on the disposition of potential preventability in 48.7% (n = 37) of cases. The statewide MMRC judged 69.7% (n = 53) of cases potentially preventable, compared with 40.8% (n = 31) for the regional perinatal centers. The MMRC identified more preventable provider and systems factors for potentially preventable deaths compared with regional perinatal centers which identified more preventable patient factors. The statewide MMRC found more potential preventability and determined that preventability was associated with provider and systems factors, not patient factors. Observed discrepancies between regional perinatal center and statewide MMRC reviews were likely due to the complexity of cases selected for review, the multidisciplinary external composition of the review team, and the de-identification of cases. Multidisciplinary statewide expert panels should be implemented in addition to local and regionalized reviews.
