To at hospitals result in the death of 210,000 to 440,000 Americans each learn more about how, when, and why medical errors occur, federal year. A 2013 study by the Inspector General of the Department of regulations established in 2003 required hospitals participating in Health and Human Services (DHHS) identified 180,000 deaths related the Medicare program to, “track medical errors and adverse patient to medical error in 2010, of which 44% were determined clearly or events, analyze their causes, and implement preventive actions and likely preventable [1]. mechanisms that include feedback and learning throughout the Based on these figures, medical errors are the third leading cause hospital.” Hospitals report this information using a federally-approved of death in America, after heart disease and cancer [2,3].
