Medicolegal cases involving periviable births from a major United States legal database.

Objective: The management of expectant mothers and infants born at the threshold of viability is challenging. We describe medicolegal cases from a major United States legal database involving periviable births in an effort to identify areas for improvement.

Study Design: We conducted a retrospective review of all United States state and federal cases in the Westlaw database from 1980 through 2016 involving peripartum and immediate post-delivery management of infants born between 22 0/7 and 25 6/7 weeks' gestation.
