目的:测量我国PET-CT配置公平性,探索分布公平性的影响因素,为提高分布公平性提供政策建议。方法:收集当前我国PET-CT配置数据,采用集中指数和泰尔指数测算PET-CT在全国各省市及东中西区域间配置的公平性。结果:当前我国各省市PET-CT配置的集中指数为0.32,其公平性较配置规划实施前有明显提升;各省市公立医院拥有PET-CT的集中指数为0.318,略低于全部PET-CT分布集中指数;我国东、中、西部区域内PET-CT分布泰尔指数为0.109,是影响分布公平性的主要因素,且东部地区内分布差异高于中部和西部地区。结论:我国PET-CT配置公平性有所提高;配置规划有利于提高PET-CT分布公平性;东、中、西部地区内部的分布差异是造成整体不公平的主要因素。
Objective: To measure the fairness of PET-CT configuration in China and explore the influencing factors of the distributional fairness, and to provide policy suggestions to improve the fairness of distribution. Methods: To collect the current PET-CT configuration data in our country and calculate the fairness of PET-CT deployment in all provinces, cities, east, central and western regions using the concentration index and the Theil index. Results: At present, the concentration index of PET-CT in all provinces and cities in our country is 0.32, the fairness of PET-CT in each province and municipality has been significantly improved compared with that before the implementation of configuration planning. The concentration index of PET-CT owned by each provincial and municipal public hospital is 0.318, slightly lower than that of all PET-CT Concentration index; The PET-CT distribution Theel index is 0.109 in the eastern, central and western regions of China, which is the main factor affecting the fairness of distribution, and the distribution difference in the eastern region is higher than that in the central and western regions. Conclusion: The fairness of PET-CT configuration in our country has been improved. The disposition planning is helpful to improve the fairness of PET-CT distribution. The distributional differences among the eastern, central and western regions are the main factors contributing to the overall unfairness.
