Objective assessment of surgical competence in gynaecological laparoscopy: development and validation of a procedure-specific rating scale.
The purpose of this study was to develop a global- and a procedure-specific rating scale based on a well-validated generic model (objective structured assessment of technical skills) for assessment of technical skills in laparoscopic gynaecology. Furthermore, we aimed to investigate the construct validity and the interrater agreement (IRA) of the rating scale. We investigated both the gamma coefficient (Kendall's rank correlation), which is a measure of the strength of dependence between observations, and the kappa value for each of the ten individual items included in the rating scale. ⋯ The procedure-specific rating scale for laparoscopic salpingectomy is a valid and reliable tool for assessment of technical skills in gynaecological laparoscopy.
