Introduction: Evidence across healthcare specialties suggests that simulation-based education improves practices and patient outcomes. However, simulation has yet to be widely used in hyperbaric medicine education. We aimed to identify the most relevant clinical scenarios for inclusion in a simulation-based curriculum for hyperbaric medicine.

Methods: After ethics approval, we used a modified Delphi consensus method. We assembled an initial questionnaire and distributed it online in English and French to an international group of hyperbaric physicians and operators using a snowball recruitment technique. Participants rated the list of scenarios using a 5-point scale ranging from 1 (least relevant) to 5 (most relevant). Scenarios judged by at least 80% of participants to be relevant (score 4 or 5) were automatically included. Scenarios that did not meet this threshold and new scenarios suggested by participants during the first round were included in a second round.

Results: Seventy-one participants from nine countries, including both physicians and non-physicians, completed the first round and 34 completed the second. Five scenarios were identified as relevant: seizure, fire, cardiac arrest, pneumothorax, and technical deficiency such as power loss while operating the chamber.

Conclusions: Five scenarios relevant for inclusion in the simulation-based curriculum in hyperbaric medicine were identified by expert consensus.
