The Quality and Safety Commission has released its report on the serious and sentinel events reported by District Health Boards (DHBs) for the period 1 July 2010 to 30 June 2011. This is the Commission's second report, and the fifth time that DHBs have publicly reported details of these events. The DHBs reported that 377 people treated in their hospitals were involved in a serious or sentinel event that was actually or potentially preventable. Falls accounted for 52% of these events, clinical management events (for example, errors of diagnosis and treatment) accounted for 29%, and medication events (for example, giving a patient the wrong medicine or the wrong dosage) were the third largest category at 7%.
