Objective: To calculate the medical service price of radium [ ²²³ Ra] bone metastases, based on the clinical data collected in Beijing, Chongqing and Guangzhou, with standardized value pricing method. It would lay a foundation for future new medical service registration, pricing and reimbursement. The research also provided a basis for compensating contribution of medical professionals and improving the accessibility of patient service items. Methods: From March to December 2021, the research collected resource consumption raw data with specifically designed "Radium Nuclide [ ²²³ Ra] Bone Metastasis treatment Resource Input and Expense Data Collection Form". The research also conducted expert interviews to assign risk and difficulty coefficients and determine baseline comparison project. Results: The treatment service for radium [ ²²³ Ra] bone metastases was divided into five stages: pre-injection assessment, treatment plan, administration, post-administration monitoring, waste disposal and monitoring. The overall time spending for each stage is 104 min,39 min,25 min,72 min and 56 min. The standardization consumable value is 48.20 yuan, and the standardized value of the newly added items is 810.19 yuan. Conclusion: This study innovatively applied the value pricing theory based on risk and difficulty coefficients, and developed a pricing tool for the new medical service radium [ ²²³ Ra]bone metastases treatment. standardized value. The pricing formula and research method can not only be used for the pricing new treatment service in nuclear medicine department, but also for dynamic price adjustment of current medical service items, filling the theoretical gap of the lack of relevant pricing research in nuclear medicine department.
