| 目的 调查2022年河南省临床核医学诊疗资源和应用基本情况,评估其分布公平性,并与河南省1998年调查结果进行对比分析,为河南省核医学诊疗资源配置提供参考。方法 对全省开展临床核医学诊疗的医疗机构进行现场调查,采用洛伦兹曲线、基尼系数和泰尔指数相结合的方式分别评估河南省1998年和2022年核医学资源和应用基于人口分布的公平性。结果 2022年河南省开展核医学诊疗的医疗机构共54家,核医学显像及配套设备67台,核医学工作人员690人,全年开展临床核医学显像诊断200 938人次,诊断频度为2.04人次/千人口,各类核医学治疗29 044人,治疗频度为0.29人/千人口。1998年河南省核医学诊疗设备、核医学工作人员和应用频度基于人口分布的基尼系数分别为0.489、0.505和0.526,泰尔指数分别为0.091 8、0.172 1和0.139 7。2022年河南省核医学诊疗设备、核医学工作人员和应用频度基于人口分布的基尼系数分别为0.244、0.246 和0.363,泰尔指数分别为0.086 8、0.145 3和0.159 9。结论 河南省临床核医学快速发展的同时,各类核医学资源和应用分布愈发平衡,但仍呈现一定的不均衡性,同时也显示出与区域经济发展水平的相关性,资源配置合理性有待进一步优化。 |

| Objective To investigate the basic information of diagnostic and therapeutic nuclear medicine resources and practices in Henan province in 2022, and to assess the equity of their distribution, and to compare them with the 1998 survey result, so as to provide the reference for the allocation of nuclear medicine resources in Henan province. Methods On-site investigations were conducted on medical institutions in Henan province that carry out diagnostic and therapeutic nuclear medicine practices. By using a combination of Lorenz curve, Gini coefficient and Theil index, the fairness of nuclear medicine resources and practices were assessed based on population distribution in Henan province in 1998 and 2022. Results In 2022, there were 54 medical institutions in Henan province that carried out diagnostic and therapeutic nuclear medicine practices, with 67 items of nuclear medicine imaging and supporting equipment, and 690 nuclear medicine staff members involved. A total of 200 938 diagnostic clinical nuclear medicine imaging practices were performed throughout the year, with a diagnostic frequency of 2.04 per 1 000 population. Various types of therapeutic nuclear medicine practices were performed on 29 044 individuals, with a frequency of 0.29 per 1 000 population. The Gini coefficients for the distribution of diagnostic nuclear medicine practices, nuclear medicine staff, and practice frequency based on population distribution in Henan province in 1998 were 0.489, 0.505, and 0.526, respectively, and the Theil indices were 0.091 8, 0.172 1, and 0.139 7, respectively. The Gini coefficients for the distribution of nuclear diagnostic medicine equipment, nuclear medicine staff, and practice frequency based on population distribution in Henan province in 2022 were 0.244, 0.246, and 0.363, respectively, and the Theil indices were 0.086 8, 0.145 3, and 0.159 9, respectively. Conclusions While clinical nuclear medicine in Henan province is rapidly developing, the distribution of various types of nuclear medicine resources and practices is becoming increasingly balanced. However, there still exists a certain degree of imbalance. Additionally, this also demonstrates a correlation between the resource distribution and regional economic development. The rationality of resource allocation needs further optimization. |
