IntroductionTo describe the design and implementation of a Crisis Resource Management (CRM) training program for the initial assessment of polytrauma patients. MethodsProspectively implemented CRM training program in acute-care tertiary hospital by hospital personnel involved in the care of polytraumatisms. The program has a blended format and 23-h duration, including 11 h of online theoretical training followed by 12-h simulation modules and practical cases devoted to the roles of members of the trauma team, functioning of the polytrauma room, and key aspects of teamwork. The Human Factors Attitude Survey (HFAS) was used to assess attitudes related to non-technical skills, and the End-of-Course Critique (ECC) survey to evaluate satisfaction with training. We evaluated changes in the pre- and post-training assessments. ResultsEighty staff personnel (26% specialists, 16% residents, 29% nurses, 14% nursing assistant, 15% stretcher bearer) participated in three editions of the program. Theoretical knowledge improved from a mean (SD) of 5.95 (1.7) to 8.27 (2.1) (P < .0001). In the HFAS, statistically significant differences in 18 of 23 attitudinal markers were observed, with improvements in all items of “leadership” and “roles”, in 4 of 5 items of “situational awareness”, and in 4 of 8 items of “communication”. Mean values obtained in the ECC questionnaire were also very high. ConclusionsA CRM training model developed for the initial care of polytrauma patients improved theoretical knowledge and participants perceptions and attitudes regarding leadership, communication, roles, and situational awareness of members of the trauma team.
