April 27, 2026- Premier, Inc. announced the publication of a new study in The Lancet Regional Health – Americas. The study introduces the maternal Prenatal Risk Index (m-PRI), a precise, mortality-informed framework for identifying patients at risk for severe maternal morbidity (SMM).
Developed in collaboration with the U.S. Department of Health and Human Services (HHS) Office on Women’s Health (OWH), the study analyzed 7,174,412 inpatient delivery hospitalizations from 2016 to 2023 across 864 hospitals in 49 states. The research builds on the HHS Perinatal Improvement Collaborative (PIC), a national initiative overseen by OWH that uses Premier’s real-time data, analytics and performance improvement methodologies to connect more than 250 hospitals nationwide. The PIC leverages standardized data to evaluate clinical practices and help improve maternal and infant outcomes.
The new study utilized Premier’s comprehensive Premier Healthcare Database (PHD), a diverse, all-payer administrative database representing approximately 25 percent of annual inpatient encounters across more than 1,400 hospitals in the United States.
