Preventable errors are common in healthcare. Over the last decade, Root Cause Analysis (RCA) has become a key tool for healthcare services to investigate adverse events and try prevent them from happening again. The purpose of this paper is highlight work New South Wales (NSW) RCA Review Committee. benefits correctly classifying, aggregating disseminating data clinicians will be discussed. In NSW, we perform an average 500 RCAs per year. It estimated that each takes between 20 90 h perform....
