Abstract:
Objective:To investigate the current status of diagnostic X-ray resources in Jinan in order to provide theoretical basis for continuously optimizing the allocation of diagnostic resources and strengthening the management of radiological health and radiation protection.Methods:In accordance with the 2023 Jinan radiation protection monitoring program of medical and health institutions, a survey was carried out for medical institutions involved in diagnostic X-ray examinations (excluding military hospitals and dental clinics) in Jinan by using uniform questionnaires. The survey included the basic situation of diagnostic X-ray institutions, the allocation of diagnostic X-ray equipment, the number of diagnostic staff, and the frequency of diagnositic X-ray examinations.Results:In 2023, there were 298 diagnostic X-ray institutions in Jinan, with 3 494 diagnostic workers and 1 387 items of diagnostic X-ray equipment. The included were 41 tertiary hospitals, 57 secondary hospitals, 110 primary hospitals and 90 unrated hospitals. The tertiary hospitals possessed the largest number of the diagnostic workers and equipment, accounting for 60.99% and 45.35% of the total, respectively. Among all the items of diagnostic X-ray equipment, the number of items of digital radiography equipment ranked top (34.37%), followed by CT machines (24.44%). There were 147.32 items of diagnostic X-ray equipment per million population on average. A total of 8 180 363 individuals received various types of diagnostic X-ray examinations, with CT diagnosis accounting for 46.93% and X-ray for 34.41%. The frequency of diagnostic X-ray examinations was 868.86/1 000 population, including the frequency of CT examinations of 407.76 per 1 000 population.Conclusions:The per capita possession of medical X-ray equipment in Jinan is at a high level. The frequency of medical exposure has increased significantly, especially CT examinations. There is a big gap in diagnostic X-ray resource allocation between different levels of hospitals, so it is necessary to control the resource allocation and strengthen the protection of CT examination on the scientific basis.
