| To optimize the allocation of oncological medical resources and improve the efficiency and safety of clinical diagnosis and treatment, Shanxi Provincial Cancer Hospital has explored and constructed an integrated outpatient treatment model for malignant tumors in clinical departments. Taking the Department of Breast Surgery as a pilot, the hospital firstly implemented the clinical department-based outpatient treatment model in July 2025, and fully promoted this model across the hospital in January 2026 after stable pilot operation. This model integrates full-process services including patient registration, disease assessment, medical order issuance, clinical treatment and expense settlement within clinical departments, realizing the closed-loop management of integrated diagnosis and treatment services. Hospital information system was adopted to collect relevant clinical data to analyze the operational effect and diagnosis and treatment safety of the model. In July 2025, the Department of Breast Surgery completed the optimization of bed resources, with inpatient beds reduced from 289 to 118 and 20 supporting infusion chairs equipped. The department treated a total of 4,389 outpatient patients from July to December 2025. From January to May 2026, the hospital received 18,649 outpatient treatment patients, accounting for 40.78% of the total patients treated by departments that had implemented the outpatient treatment model during the same period. The hospital achieved a smooth transformation from the traditional treatment model relying on virtual inpatient admission to the outpatient treatment model for malignant tumors. No medication errors or severe adverse medical events caused by the reform of diagnosis and treatment model occurred during the whole process. This practice proves that the integrated clinical department-based outpatient treatment model for malignant tumors is feasible and clinically safe. The model can optimize the allocation of medical resources and standardize the outpatient diagnosis and treatment procedures for tumors, which presents high value for clinical promotion and application. |
