Abstract
Background: The use of ionizing radiation in medical imaging has revolutionized the ability to diagnose and treat illness. While it is difficult to measure the risk associated with low-level radiation exposures, estimates can be made by extrapolating data from atomic-bomb survivors. Based on these estimates, the American College of Radiology has recommended steps that clinicians can take to minimize risk for patients. Studies evaluating knowledge of radiation risk have so far focused on physicians in emergency and surgical settings, finding potential gaps of significance. This study seeks to establish radiation-safety knowledge possessed by primary-care providers in the state of Vermont. Methods: A structured survey was created to assess primary-care providers' (PCPs) attitudes, practices, and knowledge about ordering CT scans and sent to PCPs within the UVMMC Health Network. Results: Survey results demonstrated a widespread lack of knowledge of CT risk. Out of a maximum score of 5 on the knowledge assessment portion, the average test performance was 2.2. Average test scores were tabulated against graduation year from medical school, self-rated familiarity and knowledge with CT imaging, and levels of training in this specific area. No comparisons reached statistical significance (p<0.05). Conclusion: Despite differences in training, familiarity with CT, and professional titles, there remains a lack of knowledge regarding CT radiation safety. Further research and advancements in CT knowledge, along with increased education for medical professionals, are necessary.
