What is simulation-based medical education (SBME) debriefing in prehospital medicine? A qualitative, ethnographic study exploring SBME debriefing in prehospital medical education.

INTRODUCTION: Simulation-based medical education (SBME) debriefing - a construct distinct from clinical debriefing - is used following simulated scenarios and is central to learning and development in fields ranging from aviation to emergency medicine. However, little research into SBME debriefing in prehospital medicine exists. This qualitative study explored the facilitation and effects of prehospital SBME debriefing, and identified obstacles to debriefing, using the London's Air Ambulance Pre-Hospital Care Course (PHCC) as a model. METHOD: Ethnographic observations of moulages and debriefs were conducted over two consecutive days of the PHCC in October 2019. Detailed contemporaneous field notes were made and analysed thematically. Subsequently, seven one-to-one, semi-structured interviews were conducted with four PHCC debrief facilitators and three course participants to explore their experiences of prehospital SBME debriefing. Interview data were transcribed and analysed thematically. RESULTS: Four overarching themes were identified: approach to facilitation of debriefs, effects of debriefing, facilitator development, and obstacles to debriefing. The unpredictable debriefing environment was seen as both hindering and, paradoxically, benefitting SBME debriefing. Despite using varied debriefing structures, facilitators emphasised similar key debriefing components including exploring participants' reasoning and sharing experiences to improve learning and prevent future errors. Debriefing was associated with three effects: releasing emotion; learning and improving, particularly compound learning as participants progressed through sequential scenarios; and the application of learning to clinical practice. Facilitator training and feedback were central to facilitator learning and development. Several obstacles to debriefing were identified, including mismatch of participant and facilitator agendas, pressure and time. CONCLUSIONS: SBME debriefing in prehospital medicine is complex, requiring an understanding of participant agendas and facilitator experience to maximise participant learning. Aspects unique to prehospital SBME debriefing were identified, notably, the unpredictable debriefing environment, and the paradoxical benefit of educational obstacles for learning. Aspects of SBME debriefing not extensively detailed in the literature were also highlighted, such as compound participant learning, facilitator candour, and facilitator learning, which require further exploration.
