Surgical EducationEstablishing the concurrent validity of general and technique-specific skills assessments in surgical education

- We evaluate concurrent validity between a general and laparoscopic assessment tool.
- We demonstrated near total correlation between the 2 scales.
- Questioning the need for a laparoscopic specific tool.
- One tool would lead to more consistent nomenclature and standardized assessments.

BackgroundLaparoscopic surgery entails a unique skill set, but it is unclear whether it requires a specific assessment form or whether more general assessment tools can be applied. The purpose of this study was to assess the concurrent validity of 2 previously validated assessment scales. One scale designed specifically to assess laparoscopic skills and the other to assess more general surgical skills.MethodsPostgraduate year 1-6 general surgery and urology residents (n = 33) performed a live laparoscopic cholecystectomy. Three surgeon raters scored their performance using previously validated objective structured assessment of technical skills (OSATS) and global operative assessment of laparoscopic skills rating scales.ResultsPearson's correlation coefficient between global operative assessment of laparoscopic skills and OSATS rating scales was .975 (P = .01).ConclusionsThe near total correlation between the 2 scales questions the need for separate laparoscopic assessment tools, highlighting the real strengths of OSATS, the use of which allows for more consistent nomenclature and standardized skills assessment across surgical platforms.
