This document discusses post-trauma resuscitation debriefing. It defines debriefing as a facilitated discussion of actions and thought processes during a trauma resuscitation to encourage reflection and improve future performance. Debriefing should identify the underlying rationales behind behaviors and occur immediately after the event with the entire multi-professional trauma team. The Plus-Delta-Discuss method is recommended, focusing on what went well, what could be improved, and discussing keys to success and barriers. Debriefing has been shown to improve performance in trauma resuscitations when done focused, succinctly and without blame.
