Development and validation of the first performance assessment scale for interdisciplinary chest tube insertion: a prospective multicenter study.

PURPOSE: Chest tube insertion requires interdisciplinary teamwork including an emergency surgeon or physician in conjunction with a nurse. The purpose of the study was to validate an interdisciplinary performance assessment scale for chest tube insertion developed from literature analysis. METHODS: This prospective study took place in the simulation center of the University of Paris. The participants included untrained emergency/intensivist residents and trained novice emergency/intensivist physicians with less than 2 years of clinical experience and 6 months following training in thoracostomy, and nursing students. Each interdisciplinary pair participated in a high-fidelity simulation session. Two independent observers (O1 and O2) evaluated 61 items. Internal coherence using the Cronbach's α coefficient, intraclass correlation coefficient (ICC), and correlation of scores by regression analysis (R2) were analyzed. Comparison between O1 and O2 mean scores used a t test and F test for SDs. p Value < 0.05 was significant. RESULTS: From an initial selection of 11,277 articles, 19 were selected to create the initial scale. The final scale comprises 61 items scored out of 80, including 24 items for nursing items, 24 items for medical competence, and 13 mixed items for the competence of both. 40 simulations including 80 participants were evaluated. Cronbach's α = 0.76, ICC = 0.92, R2 = 0.88. There was no difference between the observers' assessments of means (p = 0.82) and SDs (p = 0.92). Score was 51.6 ± 5.9 in the group of untrained residents and nursing student, and 57.2 ± 2.8 in the trained group of novice physicians and nursing students (p = 0.0003). CONCLUSIONS: This first performance assessment scale for interdisciplinary chest tube insertion is valid and reliable.
