广东省CT、PET-CT配置现状调查及平衡性分析

The Investigation of CT, PET-CT in Guangdong Province and the Analysis of Balance

目的对广东省各地市CT、PET-CT机配置现状及平衡性进行分析,为卫生行政部门优化卫生资源配置提供科学依据。方法通过实地调查、问卷调查、文献调查(咨询卫生管理部门)等方法收集广东省各地市2012年度CT、PET-CT机配置现状的数据,绘制出劳伦兹曲线(Lorenz curve),计算基尼系数(Gini coefficient)和卫生资源密度指数(HRDI)等方法,评价广东省CT、PET-CT机按人口及地理分布的平衡性。结果广东省各地市CT机资源按人口分布洛伦兹曲线位于平衡线附近;按地理分布洛伦兹曲线偏离平衡线较远,中度不平衡。广东省CT机按人口配置的Gini系数为0.15,按地理配置的Gini系数为0.44。粤北地区的韶关、清远及粤西地区的湛江、云浮HRDIi/HRDI标准值较小;广州、东莞等粤中较发达地区HRDIi/HRDI标准值则远大于1。PET-CT机广东省目前配置总量为11台,位于珠江三角洲地区的广州、深圳、佛山、东莞四地市占有全省PET-CT机资源的90.90%(10/11)。结论广东省CT机总量趋于合理,人口平衡性较好,但地理平衡性差,粤西、粤北地区配置情况相对较差。PET-CT机配置人口、地理分布均不均衡,珠三角地区过于集中。

Objective To study CT, PET-CT configuration status and analyze the balance in Guangdong Province. Methods Field surveys, questionnaires, a literature survey （consulting health management sector） and other methods were used to collect the data of CT, PET-CT configuration status in 2012 in all prefectural cities of Guangdong Province; Lorenz curve was drawn, Gini coefficient and the Health Resources Density Index （HRDI） were calculated to evaluate the balance of CT, PET-CT distribution by population and geography in Guangdong Province. Results CT in all prefectural cities of Guangdong Province： Lorenz curve by population distribution was near the equilibrium line, and Lorenz curve by geographical distribution deviated far from the equilibrium line, moderately imbalanced; Gini coefficient by population configuration was 0.15, and Gini coefficient by geographical configuration was 0.44. In Shaoguan, Qingyuan of northern Guangdong and Zhanjiang, Yunfu of western Guangdong, HRDIi / HRDI standard value was small; in Guangzhou, Dongguan, and other more developed regions of central Guangdong, HRDIi / HRDI standard value was 〉 1. PET-CT in Guangdong Province was currently configurated 11, in which Guangzhou, Shenzhen, Foshan and Dongguan located in the Pearl River Delta region occupied 90.90% （10/11） of all PET-CT resources in Guangdong Province. Conclusion The total CT configuration in Guangdong Province tends to rationalize, with better population balance but poorer geographic balance, especially relatively poorer configuration in western and northern Guangdong regions. PET-CT configuration is imbalanced by demographic or geographic distribution, too concentrated in the Pearl River Delta region.
