Design and Validation of a Novel Assessment Tool for Laparoscopic Suturing of the Vaginal Cuff during Hysterectomy

ObjectiveThe aim of this study was to design and validate a new assessment tool for laparoscopic vaginal cuff suturing in a box trainer.DesignA primary grading tool was constructed including a novel checklist component and a previously validated global rating scale. A four-step validation process was then undertaken. Face validity was determined by a survey of a panel of experts in the field of minimally invasive gynecologic surgery. Content validity was assessed via analysis of consistency and variability of the experts’ ratings, and items were removed or rephrased according to the experts’ comments.ParticipantsOverall, five novices and five expert laparoscopic surgeons were videotaped performing suture closure of a latex vaginal cuff model in a box trainer. The videotapes were reviewed by two raters. Discriminate validity, along with interrater and intrarater reliabilities, was assessed by analysis of the video ratings.SettingThe Simulation, Training, Research, and Technology Utilization System center at Brigham and Women’s Hospital, a tertiary medical center in Boston, MA.ResultsThe final assessment tool is presented.ConclusionWe have validated an assessment tool for vaginal cuff suturing in a box trainer.
