In a letter, the state’s public health commissioner said the action was taken because “confidential information provided to the Maternal Mortality Review Committee was inappropriately shared with outside individuals.”

ProPublica reported in September on the deaths of Amber Thurman and Candi Miller, which the state maternal mortality review committee had determined were preventable. They were the first reported cases of women who died without access to care restricted by a state abortion ban, and they unleashed a torrent of outrage over the fatal consequences of such laws. The women’s stories became a central discussion in the presidential campaign and ballot initiatives involving abortion access in 10 states.

“Confidential information provided to the Maternal Mortality Review Committee was inappropriately shared with outside individuals,” Dr. Kathleen Toomey, commissioner of the state Department of Public Health, wrote in a letter dated Nov. 8 and addressed to members of the committee. “Even though this disclosure was investigated, the investigation was unable to uncover which individual(s) disclosed confidential information.

“Therefore, effective immediately the current MMRC is disbanded, and all member seats will be filled through a new application process.”
