Clinical events reported by surgeons assessing their peers.

Background: All surgical deaths in Queensland, Australia are reviewed by external surgeon peers, and clinical events are recorded. The study objective was to classify clinical events in surgical patients who died.

Methods: Deaths notified to the Queensland Audit of Surgical Mortality between 2007 and 2013 were assessed by surgeons' peers who decided whether a clinical event occurred. The most serious clinical event per patient was analyzed.

Results: Peer surgeons reviewed 4,816 deaths. Most patients (70.7%) had no clinical event. Events were preventable in 58% of patients and less than 1 in 10 events was severe. The most frequent events were classified as patient assessment (34.5%), suboptimal therapy (15.3%), and delays (15.1%).

Conclusions: Peer review of all surgical deaths identifies preventable clinical events and provides opportunities to improve decision making, better therapy and reduce delay in implementing appropriate surgical care. Review feedback to surgeons and other stakeholders should improve patient safety and quality.
