Performance Assessment of Emergency Teams and Communication in Trauma Care (PERFECT checklist)—Explorative analysis, development and validation of the PERFECT checklist: Part of the prospective longitudinal mixed-methods EPPTC trial

BACKGROUND: Trainings in emergency medicine are well structured, but examinations are rarely validated. We are evaluating the impact of pre-hospital emergency trainings on participants and patient care and developed and validated a checklist to assess emergency trainings. METHODS: We used videos recorded at the time points directly before (t0), directly after (t1), and one year after (t2) training to develop the PERFECT checklist (Performance Assessment of Emergency Teams and Communication in Trauma Care). The videos were assessed using semi-qualitative/linguistic analysis as well as expert panel appraisal and recommendations using the Delphi method. The checklist was tested for validity and reliability. RESULTS: The inter-rater reliability (ICC = 0.99) and internal consistency (α = 0.99) were high. Concurrent validity was moderate to high (r = 0.65 –r = 0.93 (p<0.001)). We included scales for procedures, non-technical skills, technical skills and global performance. The procedures were done faster in the mean over the timeline (t0: 2:29, 95%CI 1:54–3:03 min., t1: 1:11, 95%C 0:53–1:30 min, t2: 1:14, 95%CI 0:56–1:31 min.). All experts rated the recorded scenarios at t0 with the lowest sum score (mean 31±8), with a significantly better performance of the teams at t1 (mean 69±7). The performance at t2 (mean 66 ± 13) was slightly lower than at t1, but still better than at t0. At t1 and t2, linguistic analysis showed a change in the team leaders communication behaviour, which can be interpreted as a surrogate parameter for reduced stress. CONCLUSION: The PERFECT checklist has a good validity and high reliability for assessing trauma procedures and teamwork
