Modifies provisions relating to peer review committees

HB 322 modifies Missouri's law governing peer review committees, which evaluate healthcare quality and provider performance. It defines "peer review committees" broadly to include groups formed by medical societies, hospitals, health maintenance organizations, or universities. Key changes include granting legal immunity to committee members acting in good faith and strictly protecting all committee discussions, records, and decisions from being disclosed in court or used in lawsuits - except when committees deny hospital privileges or licenses. This bill directly affects healthcare providers, hospitals, and health maintenance organizations operating in Missouri by enhancing confidentiality and limiting liability for their peer review processes.
