| Abstract:: |
| 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. |
