Adverse Events Toolkit: Medical Review Methodology

OIG has found that patient harm is common among Medicare patients in a range of inpatient health care settings. In support of Federal regulations that require that hospitals and other health care facilities identify harm, such as adverse events, and work to reduce these events, we are developing two toolkits. The Adverse Events Toolkit: Medical Review Methodology is geared toward health care teams and researchers interested in conducting adverse event medical reviews. It provides an explanation of the OIG methodology, including details about our definition of patient harm and how we categorized events by severity and preventability. It also includes tips on overcoming common challenges (such as complex cases) and quality assurance.
