Debriefing after a critical event is a strategy drawn from high reliability industries to learn from failures and improve performance. This retrospective study of critical events in inpatient anesthesiology practice found that debriefing occurred in 49% of the incidents. Debriefs were less likely to occur when critical communication breakdowns were involved, and more than half of crisis events included at least one such breakdown. Interviews with care teams revealed that communication breakdowns present in some incidents impeded the subsequent debriefing process. The authors call for more consistent implementation of debriefing as a recommended patient safety process. A previous WebM&M commentary discussed an incident involving miscommunication between a surgeon and an anesthesiologist.
