Objective  To investigate and analyze the allocation, distribution, and agglomeration degree of radiological diagnosis and treatment equipment of medical and heath institutions in Shandong Province in 2022 to provide a scientific basis for further optimizing the allocation of radiological diagnosis and treatment equipment and the high-quality development of radiological health.

Methods  A special survey information system for radiological health was established, a unified survey form was formulated, and a general survey of radiological diagnosis and treatment equipment in medical and health institutions in the province was conducted. After quality control measures such as filling in, auditing, and supervision, the number of medical and health institutions and the allocation of radiological diagnosis and treatment equipment were statistically analyzed using a pivot table, and the differences in different regions were compared.

Results  A total of 5543 medical and health institutions provide radiological diagnosis and treatment services, of which 5543 engage in diagnostic radiology, 231 offer interventional radiology, 197 provide radiotherapy, and 139 offer nuclear medicine. A total of 14349 sets of radiation diagnosis and treatment equipment are used, including 13995 sets of radiation diagnosis equipment, 300 sets of radiation therapy equipment, and 54 sets of nuclear medicine equipment. The average number of different types of radiation diagnosis and treatment equipment was 105.51 sets/district and county, and 141.10 sets/million population. The aggregation degree of medical and health institutions in each region ranged from 0.51 to 1.84, and the aggregation degree of radiological diagnosis and treatment equipment in each region ranged from 0.56 to 1.73. The distribution of radiodiagnosis and radiotherapy resources in different regions is not balanced.

Conclusions  The development of radiological diagnosis and treatment resources is rapid in Shandong Province, and optimizing the allocation of radiological diagnosis and treatment resources among different regions is necessary. We will give greater priority to nuclear medicine policies and further increase the allocation of nuclear medicine diagnosis and treatment equipment.
