Objective Structured Assessment of Technical Skills (OSATS)

OSATS is a validated assessment tool for grading overall technical proficiency for open surgery. Each of the four domains shown below are scored on a Likert Scale between 1 - 5, a scoring anchor, with a total score range from 7 – 35. The Knowledge of Instruments, Use of Assistants, and Knowledge of Specific Procedure domains are not scored by C-SATS due to video analysis limitations. Also the ‘Pass/Fail’ question is not included. This means the total score achieved through the C-SATS platform could range from 4 – 20.
