Wrapping his wife in a blanket as she mourned the loss of her pregnancy at 11 weeks, Hope Ngumezi wondered why no obstetrician was coming to see her. Over the course of six hours on June 11, 2023, Porsha Ngumezi had bled so much in the emergency department at Houston Methodist Sugar Land that she'd needed two transfusions. But when Dr. Andrew Ryan Davis, the obstetrician on duty, finally arrived, he said it was the hospital's "routine" to give a drug called misoprostol to help the body pass the tissue, Hope recalled. Three hours later, her heart stopped. The 35-year-old's death was preventable, according to more than a dozen doctors who reviewed a detailed summary of her case for ProPublica.
