Background And Aims:
Non-technical skills (NTS), involving cognitive, social and interpersonal skills that complement technical skills, are important for the completion of safe and efficient procedures. We investigated the impact of a simulation-based curriculum with dedicated NTS training on novice endoscopists' performance of clinical colonoscopies.
Methods:
A single-blinded randomized controlled trial was conducted at a single center. Novice endoscopists were randomized to a control curriculum or a NTS curriculum. The control curriculum involved a didactic session, virtual reality (VR) simulator colonoscopy training, and integrated scenario practice using a VR simulator, a standardized patient, and endoscopy nurse. Feedback and training were provided by experienced endoscopists. The NTS curriculum group received similar training that included a small-group session on NTS, feedback targeting NTS, and access to a self-reflective NTS checklist. The primary outcome was performance during two clinical colonoscopies, assessed using the Joint Advisory Group Direct Observation of Procedural Skills (JAG DOPS) tool.
Results:
Thirty-nine participants completed the study. The NTS group (n = 21) had superior clinical performance during their first (P < 0.001) and second clinical colonoscopies (P < .0.001), compared to the control group (n = 18). The NTS group performed significantly better on the VR simulator (P < 0.05) and in the integrated scenario (P < 0.05).
Conclusion:
Our findings demonstrate that dedicated NTS training led to improved performance of clinical colonoscopies among novices.

Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
