RationaleAlthough medical simulation is increasingly being used in healthcare education, there are few examples of how to rigorously design a simulation to evaluate and study important communication skills of intensive care unit (ICU) clinicians.ObjectivesTo use existing best practice recommendations to develop a medical simulation to study conflict management in ICUs, then assess the feasibility, acceptability, and realism of the simulation among ICU clinicians.MethodsThe setting was a medical ICU of a tertiary care, university hospital. Participants were 36 physicians who treat critically ill patients: intensivists, palliative medicine specialists, and trainees. Using best-practice guidelines and an iterative, multidisciplinary approach, we developed and refined a simulation involving a critically ill patient, in which the patient had a clear advance directive specifying no use of life support, and a surrogate who was unwilling to follow the patient's preferences. ICU clinicians participated in the simulation and completed surveys and semistructured interviews to assess the feasibility, acceptability, and realism of the simulation.Measurements And Main ResultsAll participants successfully completed the simulation, and all perceived conflict with the surrogate (mean conflict score, 4.2 on a 0-10 scale [SD, 2.5; range, 1-10]). Participants reported high realism of the simulation across a range of criteria, with mean ratings of greater than 8 on a 0 to 10 scale for all domains assessed. During semistructured interviews, participants confirmed a high degree of realism and offered several suggestions for improvements.ConclusionsWe used existing best practice recommendations to develop a simulation model to study physician-family conflict in ICUs that is feasible, acceptable, and realistic.
