Birthing Friendly is a CMS designation reflecting a hospital's attestation to participating in a perinatal quality improvement collaborative and implementing recommended safety practices. It records reported structure and participation. It is not an outcome measure, and CMS published no obstetric outcome scores at all for 2024 — see the blackout.
A limit we will not cross. Nothing on this page links a clinical outcome rate to a legal claim. Adverse-event rates measure medicine. Litigation measures a legal process. They are different quantities, they are collected by different agencies for different reasons, and correlating them would be the fastest way to publish something false. Where we present clinical data and legal data together, it is to describe a market — never to imply that one causes, predicts, or justifies the other.
