Does the Observational Clinical Human Reliability Assessment (OCHRA) system provide an objective assessment of technical errors during laparoscopic cholecystectomy?
The OCHRA system is a useful tool for objectively assessing technical errors and identifying hazard zones during laparoscopic cholecystectomy.
This study has confirmed that the Observational Clinical Human Reliability Assessment system provides a comprehensive objective assessment of the quality of surgical operative performance by documenting the errors, the stage of the operation in which errors are enacted most frequently, and where these errors have serious consequences (hazard zones).
