Abstract:
Objective To investigate and analyze the resources and application frequency of radiological diagnosis and treatment in Jinan City in 2023 and provide a basis for the rational application of radiological diagnosis and treatment resources and strengthening radiological health protection management. Methods The health administrative department issued a work plan. A general survey was conducted on radiological diagnosis and treatment institutions (excluding dental clinics) in Jinan City using a questionnaire. The survey covered the basic information of the radiological diagnosis and treatment institutions, the distribution of the radiological diagnosis and treatment equipment, the number of radiological workers, and the frequency of radiological diagnosis and treatment. Results There were 301 radiological diagnosis and treatment institutions in Jinan City, with 1603 sets of radiological diagnosis and treatment equipment and 5789 radiological workers. These institutions included 41 (13.62%) tertiary hospitals, 57 (18.94%) secondary hospitals, 110 (36.54%) primary hospitals, and 93 (30.90%) ungraded hospitals. Tertiary hospitals had the highest proportions of radiological diagnosis and treatment equipment and workers, accounting for 49.53% and 69.10% of the total, respectively. The frequencies of radiological diagnosis and treatment were 868.86 X-ray diagnostic imaging examinations per 1000 population, 5.07 radiotherapies per 1000 population, 14.19 interventional diagnostic and therapeutic procedures per 1000 population, 7.36 nuclear medical diagnostic procedures per 1000 population, and 0.56 nuclear medical therapeutic procedures per 1000 population. The frequency of CT diagnosis was the highest, reaching 407.76 procedures per 1000 population. Conclusion The radiological diagnosis and treatment resources and activities in Jinan City were mainly concentrated in tertiary hospitals, with unbalanced distribution among hospitals of different grades. It is necessary to apply various medical radiations correctly and reasonably and strengthen radiation protection to reduce the frequency of radiation and the collective effective dose.
