A High-Definition Video Teaching Module for Thyroidectomy Surgery.

ABSTRACT

OBJECTIVE: With the changing landscape of postgraduate surgical education to competency-based curricula, there emerges a need for alternative forms of training. Video teaching modules have been shown to be effective tools in surgical education, complementing traditional postgraduate curricula. There is a lack of validated modules described in the literature, specifically for teaching thyroidectomy. The primary objective of this study was to develop and validate a high definition video-based teaching module instructing thyroidectomy surgery to Otolaryngology-Head and Neck Surgery trainees. DESIGN: This prospective study included intermediate to senior Otolaryngology-Head and Neck Surgery residents. Each participant first performed a thyroid lobectomy, serving as the initial assessment. After a washout period of at least 3 weeks, each participant was given the teaching module. The 15-minute module was developed using a 3-camera system and detailed a step-by-step approach to the surgery. After exposure to the module, each trainee performed the same procedure. Recordings of both procedures were deidentified and reviewed by a blinded, independent evaluator. Scoring was done using the Observational Clinical Human Reliability Assessment (OCHRA) system. SETTING: University of Alberta Hospital and Royal Alexandra Hospital, Edmonton, Alberta, Canada. PARTICIPANTS: A total of 6 intermediate to senior Otolaryngology-Head and Neck Surgery residents entered and completed the study. RESULTS: The mean error rate was 8.8 errors per procedure before module exposure and 4.5 errors per procedure after exposure, representing a 49% decrease in error occurrence (p < 0.05). The mean staff takeover event rate was 10.5 takeovers per procedure prior to module exposure and 5.0 takeovers per procedure after exposure, representing a 52% decrease in error occurrence (p < 0.05). CONCLUSION: High-definition video teaching modules are a useful complement to traditional surgical training. In a climate where new innovations for teaching thyroid surgery are needed, properly constructed and validated video teaching modules can serve as important tools in supplementing traditional surgical training.
