Brief summary

This study describes the development and validation of a structured training and assessment curriculum (STAC) for a basic laparoscopic procedure. The investigators hypothesized that residents trained using the STAC curriculum would demonstrate superior technical skills in the operating room compared to residents that were trained using a traditional curriculum.

Detailed description

The objective of this study was to develop and validate an ex-vivo comprehensive curriculum for a basic laparoscopic procedure. Although simulators have been well validated as tools to teach technical skills, their integration into comprehensive curricula is lacking. Moreover, neither the effect of ex-vivo training on learning curves in the operating room (OR), nor the effect on non-technical proficiency has been investigated. This randomized single-blinded prospective trial allocated 20 surgical trainees to a structured-curriculum (STAC) group or conventional residency training. The STAC curriculum consisted of: case-based learning, proficiency-based virtual reality training, laparoscopic box training, and OR participation. After completion of the intervention, all participants performed 5 sequential laparoscopic cholecystectomies in the OR. The primary outcome measure was the difference in technical performance between the 2 groups during the first laparoscopic cholecystectomy. Secondary outcome measures included differences with respect to: learning curves in the OR, technical proficiency of each sequential laparoscopic cholecystectomy, and non-technical skills.

Design outcomes

Primary

MeasureTime frameDescription
Technical skills6 monthsParticipants' technical skills will be assessed in the operating room as they perform a laparoscopic cholecystectomy under supervision. The procedure will be video-recorded and sent for assessment to a blinded evaluator. Technical skills will be assessed using a previously validated technical skills assessment tool (Objective Structured Assessment of Technical Skill - OSATS)

Secondary

MeasureTime frameDescription
cognitive knowledge6 monthsStudy participants will complete a multiple choice quiz designed to assess congitive knowledge relating to performing laparoscpoic cholecystectomy.
