ST. PAUL, MN (KDAL) - The number of reportable adverse events in Minnesota hospitals, ambulatory surgical centers and community behavioral health hospitals increased from 305 in 2010 to 316 in 2011, according to a report released by the Minnesota Department of Health (MDH). Despite the increase, the number of events resulting in serious injury or death to a patient decreased from 107 in 2010 to 89 in 2011. This is the lowest level of harm since 2007. The eighth annual adverse health events report summarizes the number and types of events that occurred between October 7, 2010, and October 6, 2011, in the roughly 200 facilities covered by the adverse health events reporting law. The 316 events were reported by 61 hospitals and seven surgical centers around the state. Nearly all of the increase can be attributed to increases in two categories: pressure ulcers and wrong procedures. The number of pressure ulcers rose to 141, an increase of 19 percent, while reports of wrong procedures increased by 63 percent, to 26. If the number of events in those two categories had been at the same level as the previous year, total reported events would have been lower than in 2010.
