Objective Toexplore a path to improving surgical operation statistical indexes during the expansion of multi-campus hospitals.Methods In this study we selected the data from the medical records of two surgical departments(A1 and A2)from two campuses of a hospital in the first half of 2023,following by analyzing patients'general information,fourth-level surgical procedures,non-fourth-level surgical procedures,and disease types to identify the reasons for the discrepancies in the in-dicators between the two departments and make suggestions for improvement.Results The A2 department in the branch hospital performed significantly more laparoscopic procedures than the A1 department in the home hospital(P<0.01).Moreover,the prevalence of the patients diagnosed with chemotherapy and malignant melanoma in the A2 department was significantly higher than in the A1 department(P<0.01),impacting the surgical rate indicator for the branch area.Conclusion A systematic anal-ysis of medical record data can effectively pinpoint the reasons for indicator discrepancies among different campuses within the same surgical departments of a hospital.Implementing outpatient-specific disease management and encouraging admission of com-plex and critically ill patients can effectively enhance the surgical rate as well as the fourth-level surgical rate in a department.It is suggested for the home hospital and its branches to set a respective indicator management target as long as the gap in the factors influencing the surgical rate indicators is unbridgeable between the campuses.
