ABSTRACT

Introduction: Surgery contributes about 50% of all adverse events and 13% of all hospital deaths. The human factors approach has been used with considerable success for high-risk industries to study and enhance human performance of complex, dynamic and interactive. Material and methods: We analyzed videos of laparoscopic cholecystectomy specifically for the passage of the cystic pedicle dissection and quantified the movements and errors according to the scale OCHRA. Results: We analyzed 40 videos. There were a total of 5,928 movements for cystic pedicle dissection, identifying errors 1,562, which represents that 26% of the total movements were wrong. The average total movement was 148 procedures, and the error by moving average was 39 procedures. Erroneous movements of 1,562, 113 (7%) and 1,449 were consistent errors (93%) errors were inconsequential. Conclusions: The system has a feature OCHRA essential to determine the quality of the procedure evaluated, providing information on essential steps for the development of surgery, according to the technical skill required, takes a look objective of mistakes made during a surgery.
