Abstract:

Objective To analyze the current status of equipment configuration，personnel allocation，protective equipment，and clinical activities in radiological diagnosis and treatment institutions in Xi'an City，reveal resource distribution characteristics and existing issues，and provide evidence for optimizing healthcare resource allocation. Methods A census survey was conducted across 415 radiological diagnosis and treatment institutions in Xi'an City in 2024，including equipment configuration，distribution of radiation workers protective equipment，and regional distribution of diagnostic and treatment frequencies，and the survey data were analyzed using descriptive statistics. Results There were 1 526 radiological devices in 415 radiological diagnosis and treatment institutions in Xi'an City，including 1 349（88.40%） radiological diagnostic devices，30（1.97%） radiotherapy devices，28（1.83%） nuclear medicine devices and 119（7.80%） interventional radiology devices. The radiological diagnostic equipment was distributed across hospitals of all levels，the radiotherapy and nuclear medicine devices were concentrated in tertiary hospitals，and the interventional radiology equipment was primarily allocated to tertiary and secondary hospitals. There were 106 953 on-duty workers in 415 radiological diagnosis and treatment institutions，5 915（5.53%） workers were radiological personnel，with 62.08%（3 672） working in tertiary hospitals and only 5.66% in primary hospitals. There were 9 803 units/sets in 415 radiological diagnosis and treatment institutions，with radiological diagnostic protective equipment（6 169 units/sets，62.93%） being the most prevalent，followed by interventional radiological protective equipment（3 094 units/sets，31.56%）. In the analysis of 415 radiological diagnosis and treatment institutions，the total number of facilities in Weiyang District（57 institutions），Yanta District（59 institutions），and Chang'an District（54 institutions） leads the city. Among them，Yanta District had the highest number of tertiary hospitals（10 institutions），Weiyang District contained the largest proportion of unrated hospitals（29 institutions），and Chang'an District demonstrated the highest concentration of primary hospitals（20 institutions）. Collectively，Yanta District，Beilin District，Weiyang District，and Xincheng District contributed to more than 60% of the city's total radiological diagnosis and treatment volume. Conclusion Xi'an City demonstrates robust infrastructure in radiological equipment and protective resources，however，advanced equipment，specialized personnel，and protective resources are disproportionately concentrated in higher-level hospitals compared to primary institutions.
