BackgroundTeam reflexivity and peer feedback in daily clinical work can improve patient safety. However, teams do not always engage in reflection after patient care. A reason could be that team members may lack skills in engaging in team reflection. This study explores the use of interprofessional team-based simulations to encourage and equip teams for reflective conversations in the real-world clinical practice.MethodsThis was a prospective, explorative study of team members’ perceptions of the use of in situ simulation-based scenarios with critically ill patient cases to train team-based reflections and peer feedback. The study took place in two neurological wards. Prior to the intervention, a 1-day observation in each ward and semi-structured short interviews with physicians and nurses were conducted.ResultsA total of 94 staff members, 57 nurses, 8 nurse assistants and 29 physicians participated in the in situ simulation scenarios. All team members showed appreciation of the safe learning environment. The authors found that the simulations and the debriefing structure provided an opportunity for training of team reflexivity and feedback. The team members evaluated the simulation-based training very positively, and their initial reaction indicated that they found peer feedback useful for the individual and the team. This approach allowed them to reflect on their own clinical practice.ConclusionThe simulation-based training scenarios and the debriefing structure promoted team members’ team reflexivity and peer feedback skills. The method is feasible and could be used in other specialties and situations.The team members’ reactions to feedback were positive, and based on their reflections, there is a potential to increase both individual and team skills as well as improve patient treatment.
