The Application of a Performance-Based Self-Administered Intra-procedural Checklist on Surgical Trainees During Laparoscopic Cholecystectomy

INTRODUCTION: Surgical checklists are in use to reduce errors for safer surgery. We aimed to study the effect of a previously designed performance-based self-administered intra-procedural checklist on the performance of trainees during elective laparoscopic cholecystectomy. METHODS: Twenty-four laparoscopic cholecystectomies were enrolled into the study. Six surgical trainees each performed four procedures, two without the checklist and directly followed by two procedures with the checklist. A soft beeping sound reminded each trainee to apply the checklist every 4 min during the procedures. The unedited videos were analysed using the human reliability analysis technique for the number of consequential errors, number of interventions by the trainer, number of instrument movements and time execution. The trainees’ satisfaction was assessed on a 5-point Likert scale questionnaire. Nonparametric test was used for data analysis. p value was defined as significant when p < 0.05. RESULTS: Participants performed statistically better with the application of the checklist compared to when no checklist was used, respectively: Median [IQR] total number of errors 1.51 [0.80] versus 3.84 [1.42] (p = 0.002) and consequential errors 0.20 [0.12] versus 0.45 [0.42] (p = 0.005), and the number of instrument movements per time decreased from 11.90 [5.34] to 10.38 [5.16] (p = 0.04). With the introduction of the checklist, the number of interventions by the trainer per time decreased from 2.79 [1.85] to 0.43 [1.208] (p = 0.003). The trainees satisfaction score was 4.5 [1] for the first question, 4 [1] for the second question and 4 [2] for the third question. CONCLUSION: The self-administered intra-procedural checklist improved the performance of surgical trainees and decreased the number of interventions by the trainer during laparoscopic cholecystectomy. The trainees were generally satisfied using the checklist during the procedures.
