Objective To further optimize the performance appraisal system based on resource based relative value scale (RBRVS) by evaluating the surgical operation ability of surgeons. Methods From January 1, 2019 to December 31, 2019, all patients in diagnosis related groups（DRG）group named laparoscopic cholecystotomy without common bile duct exploration and code 51.2300 in International Classification of Diseases ICD-9-CM-3 were retrospectively collected. The key indicators related to surgical operation ability of surgeons were selected through literature review and expert interviews, and the evaluation model of surgical operation ability of surgeons was established by principal component analysis. Results The RBRVS coefficients of each operation were further modified by the constructed evaluation model of surgeons' surgical ability. After adjustment, the RBRVS coefficients of different surgeons were different. Conclusion The evaluation model of surgical operation ability of surgeons is operable, which can reflect the difference of different doctors' level and ability in the treatment of the same medical service item, and promote the refined development of hospital performance management.
