This paper describes the development and implementation of the INFO (immediate, not for personal assessment, fast facilitated feedback, and opportunity to ask questions) clinical debriefing process. INFO enabled charge nurses to facilitate a group debriefing after critical events across three adult emergency departments (EDs) in Calgary, Alberta. Prior to implementation at our institutions, ED critical event debriefing was a highly variable event. Post-implementation, INFO critical event debriefings have become part of our ED culture, take place regularly in our EDs (254 documented debriefings between March 2016 and September 2017), with recommendations arising from these debriefings being introduced into clinical practice. The INFO clinical debriefing process addresses two significant barriers to regular ED clinical debriefing: a lack of trained facilitators and the focus on physician-led debriefings. Our experience shows that a nurse-facilitated debriefing is feasible, can be successfully implemented in diverse EDs, and can be performed by relatively inexperienced debriefers. A structured approach means that debriefings are more likely to take place and become a routine part of improving team management of high stakes or unexpected clinical events.
