BackgroundCompetency-based medical education has renewed focus on the attainment and evaluation of resident skill. Proper evaluation is crucial to inform educational interventions and identify residents in need of increased training and supervision. Currently, there is a paucity of studies rigorously evaluating resident chest tube insertion skill.Materials And MethodsResidents of all training levels before their intensive care unit rotation or currently rotating through the intensive care unit were invited to participate. Trainees inserted a thoracostomy tube on a high-fidelity simulator. Their performances were recorded and scored by blinded raters using the validated TUBE-iCOMPT rubric. Surgical and nonsurgical residents were compared.ResultsForty-nine residents participated; 30 from nonsurgical and 19 from surgical training programs. Overall, trainees were most deficient in the "preprocedural checks" and "patient positioning and local anesthetic" domains. Surgical trainees demonstrated higher chest tube insertion skill than their nonsurgical peers (median total score 88 [interquartile range, 74-90] versus 75 [interquartile range, 66-85], respectively, P = 0.01), particularly in the "patient positioning" and "blunt dissection" domains (P = 0.01 and P = 0.03, respectively). These differences were no longer significant when controlled for experience and Advanced Trauma Life Support certification.ConclusionsOverall, surgical residents were more skilled than nonsurgical residents in tube thoracostomy placement. Relative skill deficits within the domains of chest tube insertion have also been identified among residents of different specialties. These areas can be targeted with educational interventions to improve resident performance, and ultimately, patient safety.Copyright © 2019 Elsevier Inc. All rights reserved.
