Abstract
Background: Chest tube insertion is a standard intervention for management of various injuries of the thorax. Efficient clinical training of this and similar bed-side procedures is equally demanded and improvable. Here, we propose a nouveau means of assessment and feedback using an Objective Structured Assessment of Technical Skills (OSATS) tool. The modified OSATS for chest drain insertion is evaluated in a pilot trial focusing on chest drain insertion.Methods: Participants in the pilot trial were medical students (3rd-6th year of studies, n=9), junior residents (1st-3rd post-graduate year, n=12), senior residents (4th-6th post-graduate year, n=14), and attending surgeons (n=6) from Heidelberg University. Chest drain insertions on a cadaveric porcine model were rated by experts with the modified OSATS score. Participants’ performances were videotaped and subsequently rated by two remote experts (video rating). Primary aim was to assess criterion validity of the OSATS to distinguish experience levels. Results: Kruskal-Wallis test showed significant differences between means of scores between four groups stratified by previous experience in chest tube insertion (level 0: 22.1±3.2 vs. level 1: 26.8±2.8 vs. level 2: 35.4±2.2 vs. level 3: 41.0±2.0; p=0.002; p1,3=0.049, p0,3=0.005). However, if groups were stratified by formal professional level, no statistically significant distinction could be made using OSATS. Hence, the OSATS tool showed criterion validity for differentiation between experience levels.Conclusion: In the pilot study, the modified OSATS for chest tube insertion was apt to standardize expert rating and could be used to measure skill and to depict different experience levels. The OSATS will help facilitate training and assessment of chest drain insertion and could therefore improve surgical training for trauma situations. According to our data, the OSATS might be integrated into modern curricula.
