IP also could occur accidentally to patients who do not undergo such procedures; such accidental IP (AIP) is suggestive of lapses in safe care. This study assessed the risk for AIP in patients hospitalized with specific diagnoses who underwent specific procedures. RESEARCH DESIGN: We analyzed 7.5 mill…

METHODS: Data were from 136 commercial health plans particip…
