Program for laparoscopic urologic skills: a newly developed and validated educational program

Abstract

Objective: To develop and evaluate a program for laparoscopic urologic skills (PLUS) to determine the face, content, and construct validation to achieve uniformity and standardization in training residents in urology.

Methods: The PLUS consists of 5 basic laparoscopic tasks. Three tasks were abstracted from the Fundamentals of Laparoscopic Surgery program, and 2 additional tasks were developed under continuous evaluation by expert urologists. Fifty participants were recruited from different hospitals and performed the final PLUS training. They all completed a questionnaire after performance. Three outcome parameters were measured: performance quality, time, and dropped objects. The relationship between laparoscopic experience and the outcome parameters was investigated.

Results: Of the 50 participants, 13 were students, 20 were residents, and 17 were urologists. Double-log linear regression analysis for all 5 tasks showed a significant effect (effect size range 0.53-0.82; P < .0005) for laparoscopic experience on performance time. Substantial correlations were found between experience and quality ratings (log-linear regression effect size 0.37; P = .012) and the number of dropped objects (Spearman correlation effect size 0.49; P < .01). The usefulness of the PLUS model as a training tool for basic laparoscopic skills was rated 4.55 on a scale from 1 (not useful) to 5 (useful) (standard deviation 0.58; range 3-5).

Conclusion: The results of the present study indicated the face, content, and construct validity for the PLUS. The training is considered appropriate for use as a primary training tool for an entry test or as part of a step-wise training program in which basic and procedural laparoscopic skills are integrated.
