Abstract:

Objective To understand the allocation of radiological diagnosis and treatment resources and the application status of radiological diagnosis and treatment in Xuzhou City，providing data support for health administrative departments to optimize resource allocation and health supervision agencies to implement precise upervision. Methods Using a unified survey form，we conducted a census of all medical institutions in Xuzhou to collect information on the number of radiological staff，configuration of diagnostic and treatment equipment，and application frequency of radiological diagnosis and treatment from April 1，2023 to March 31，2024. Combined with Xuzhou's population data，the application frequency of each radiological diagnosis and treatment project was calculated. Results There were 540 medical institutions，3 572 radiological staff members，and 1 455 radiological diagnostic and treatment devices in Xuzhou. The average number of radiological devices per million population in Xuzhou was 161.36，with the highest in Quanshan District（391.70 units） and the lowest in Pizhou City（111.55 units）. The average number of radiological staff per million population was 396.13，with the highest in Quanshan District（1 256.80） and the lowest in Feng County（240.30）. The application frequency of radiological diagnosis and treatment was 944.04 person-times per thousand，with X-ray diagnosis having the highest frequency of 929.82 person-times per thousand，radiotherapy having the lowest frequency of 1.08 person-times per thousand，interventional treatment having a frequency of 8.39 person-times per thousand，and nuclear medicine diagnosis and treatment having a frequency of 4.74 person-times per thousand. Among X-ray diagnoses，the CT frequency was 521.83 person-times per thousand，mammography frequency was 6.04 person-times per thousand，and dental photography frequency was 55.54 person-times per thousand. Conclusion The radiological diagnostic and treatment resources in Xuzhou have grown rapidly，particularly CT scanners and dental machines，but there is an imbalance in the allocation of radiological resources among different regions and medical institutions of different levels. Health administrative departments should strengthen macro-control to make the allocation of radiological resources more scientific and rational. The application frequency of radiological diagnosis and treatment has increased rapidly，especially CT examinations. Medical institutions should strengthen the judgment of radiation justification and rationally use radiological diagnostic and treatment equipment. Health supervision agencies should strengthen supervision over dental clinics and the application of CT examinations in medical institutions，particularly the use of CT examinations in routine physical examinations by health examination institutions，to reduce the radiation dose received by examinees and protect their health.
