Abstract:
Objective:To understand the radiation protecton awareness of clinical staff for patients, and to provide strategies and suggestions for promoting the justification of medical exposure.Methods:From June to September 2023, 1 430 physicians or technicians from 10 tertiary hospitals, 9 secondary hospitals and 8 primary hospitals in Shanghai were selected by multi-stage stratified random sampling method to conduct a questionnaire survey about radiation-related cognition through a combination of offline and online survey. The contents of the questionnaire included the characteristics of the respondents, the training of radiation protection, the self-awareness of patients on radiation protection, the actual cognition of the basic knowledge of ionizing radiation, the cognition of the dose caused by different types of the radiological examinations, and the ways to access knowledge of ionizing radiation. SPSS software was used for statistical analysis.Results:A total of 1 229 valid questionnaires were received, of which 82.10% respondents belonged to the clinical department and 17.90% belonged to the radiology department. 58.37% of the respondents in clinical department have received radiation-related training, and 98.64% in radiology department have done so. The overall mastery of radiation protection-related knowledge in radiology department was better than in clinical department, and the difference was statistically significant ( χ2=39.58, P<0.05). Most of the respondents tended to underestimate the radiation dose to patients from CT scans, and the proportion of the respondents who underestimated the CT doses to different sites was all greater than 45%. Logistic regression analysis showed that the contributing factors affecting radiation protection cognition are a combination of technical titles, radiation protection training to a varing degree, the level of medical institutions and their majors (95% CI of the OR values did not include 1, χ2=5.66-28.26, P<0.05). Conclusions:Most clinical staff have realized the importance of controlling the radiation dose in radiological examinations, but there is less understanding of the dose magnitude caused by different radiological examinations. Education and training are the best way to improve the awareness of ionizing radiation. Radiation protection training should be integrated into general medical education or standardized training for physicians.
