| Abstract:: |
| Objective To grasp the basic information on medical institutions, radiodiagnostic equipments and X-ray diagnosis frequency in Nanjing, in order to provide the health administration department with the basis to rationally allocate medical and health resources. Methods Using the census method, the work plan was issued in the form of a document by the health administration department, and the radiodiagnostic institutions filled in the relevant questionnaires on the Jiangsu Province Radiological Health Information Management Platform. The frequencies of X-ray diagnosis were obtained by dividing the number of people invloved in X-ray diagnoses by the total number of permanent residents at the end of 2019 in Nanjing. Results There were 347 radiodiagnostic institutions in Nanjing, including 27 tertiary hospitals, 52 secondary hospitals, 159 primary hospitals and 109 unrated hospitals. There were 3 270 radiation workers and 1 285 X-ray diagnostic equipment of various types in Nanjing, and 69.23% equipment and 44.57% radiation workers are concentrated in tertiary hospitals. Among all types of X-ray diagnostic equipment in the city, DR machines have the largest number (37.59%), followed by dental machines (20.70%). The total number of X-ray diagnosic examinations in the city was 8 563 487, with routine X-ray diagnosis accounting for 55.28%, CT diagnosis for 35.98%. Frequencies was estimated to be 1 007.47 examinations per 1 000 population in medical X-ray diagnosis, of which frequency of routine X-ray diagnosis was 556.90 per 1 000 population, the frequency of CT diagnosis was 362.46 per 1 000 population, the frequency of other diagnoses was 80.03 per 1 000 population, and the frequency of interventional treatment was 8.08 per 1 000 population. X-ray diagnostic examination was mainly concentrated in tertiary hospitals (62.23%), higher in the urban area than that in the suburban area. Conclusions The basic information on radiation diagnostic institutions and the current status of X-ray diagnostic frequency in Nanjing are initially ascertained. There are obvious deficiencies in the staffing of radiation in the primary and ungraded hospitals, and urban areas were superior to suburbs in medical resources. It is desirable to enhance the macroeconomic regulation of radiodiagnosis and treatment resources in order to protect the health and safety of patients and examinees and reduce the dose to the public. |
