Radiologic technologists' radiation safety knowledge in India: A multicenter survey

摘要

Purpose: To assess radiation safety knowledge of radiologic technologists in India, assess the effect of current technologist training programs on radiation safety knowledge, and identify knowledge gaps. Method: A total of 174 radiologic technologists from 31 centers completed a survey containing theoretical and practical questions assessing radiation knowledge. Scores were analyzed based on years of experience and prior radiation training. Group mean scores were analyzed with students' t test and one-way analysis of variance. The Fisher exact test was used to analyze the difference in performance between the trained and untrained groups. Results: Thirty-two percent of the 174 respondents had received formal radiation safety training. The mean score on the questionnaire was 6.98 out of 14 total points; 66.67% of respondents scored 7 (50%) or above. The mean theoretical and practical scores (out of 7 total points each) were 4.48 and 2.49, respectively. There was no statistically significant difference between theoretical and practical scores based on years of experience. The untrained group had higher mean total and practical scores but lower mean theory scores, with a statistically significant difference for total and practical scores between the trained and untrained groups. Discussion: Although many radiologic procedures are performed in India, most technologists reported not being trained in radiation safety, even though most realized that training is necessary. The lack of improvement in scores with years of experience indicates the need for continuing professional education focusing on the practical aspects of safety. Conclusion: Professional continuing education programs for radiologic technologists should be integrated into every radiology department and monitored with quality and performance audits.
