Abstract:Objective：To explore the use of medical record home page data and DRGs management indexes to achieve refined management of preoperative hospitalization days. Methods：The gynecology department of acertainlargegrade A tertiarygeneral tertiary hospital was selected for the study，and the data of the home page of surgical patients’medical record from January 1，2022 to December 31，2022 was extracted through the hospital information system，and the chi-square test was used for the comparison between groups of count data，and the t-test was used for the comparison between groups of measurement data conforming to normal distribution，and the nonparametric test was used for the comparison between groups not conforming to normal distribution. The test results were P < 0.05 to indicate that the differences were statistically significant. Results：The mean age，total mean hospitalization day，mean hospitalization cost and all other costs and CMI values of patients in the study group were significantly lower than those of the control group，and the differences were statistically significant. The diagnostic compliance rate of patients in the control group was significantly higher than that of the study group，and the percentage of level Ⅳ surgery in the study group was significantly higher than that of the control group. Patients with shorter preoperative hospitalization days were mostly cervical polyps，vaginal bleeding，miscarriage or gynecological inflammation，while patients with longer preoperative hospitalization were mostly with more serious diseases such as gynecological malignancies，uterine smooth muscle tumors，benign ovarian tumors，complete uterine prolapse，etc. The procedures performed were mostly transabdominal or transvaginal hysterectomy，unilateral or bilateral adnexal resection，repair of uterine supporting structures and other more complex and The procedures performed were more complex and difficult，such as transabdominal or transvaginal hysterectomy，unilateral or bilateral adnexal resection，and repair of uterine supporting structures. Conclusion：Preoperative hospitalization days are influenced by factors such as patient age，surgical level，and day surgery，and hospital administrators should develop specific measures to further reduce preoperative hospitalization days.
