Abstract：Objective To analyze the influencing factors of postoperative complications of breast cancer based on hospital level and patient level with the use of the twolevel logistic random effect model, so as to provide a basis for improving the quality of breast cancer treatment in the hospital and improving the prognosis of patients. Methods information questionnaire was formulated of breast cancer patients′ medical records, and the information of breast cancer patients′ cases was collected; univariate analysis was performed on the related factors of postoperative complications of breast cancer by t-test or chi-square test. The hospital as the two-level unit, the patient as the one-level unit, whether patients with postoperative complications as outcome variables, and the influence factors of complications as the explained variable, factors with statistical significance in univariate analysis included, two-level logistic random effect model was used for multivariate influencing factor analysis. Results Totally 3 224 patients were collected; the incidence of postoperative complications of breast cancer was 22.52%; the results of two-level Logistic random effect model showed that the hospital level random effect had statistical significance in the zero model (P＜0.05). Among the explanatory variables at hospital level, hospital type (OR=0.130, 95%CI: 0.027-0.638) was statistically significant. Among the explanatory variables for patient level, age (OR=0.983, 95%CI: 0.972-0.994), residence (OR=0.671, 95%CI: 0.534-0.843), preoperative cytological examination (OR=1.973, 95%CI:1.397-2.787) and axillary lymph node metastasis (OR=1.435, 95%CI:1.168-1.762) were statistically significant (P<0.05). Conclusion The younger the age, and women living in the city are the high-risk group of complications after breast cancer; in the process of postoperative
