Despite having robust radiation safety education procedures and policies, our vascular surgery residency and fellowship program trainees exceeded the annual radiation exposure limits. We conducted a quality improvement project to identify the root causes and implemented interventions to improve radiation safety education, oversite, and trainee exposure levels. The interventions, including policy changes, curriculum improvements, and equipment updates, were successful in reducing radiation exposure, particularly at a specific hospital site.
Objective: Despite having robust radiation safety education procedures and policies in place, we discovered that the trainees at our Accreditation Council for Graduate Medical Education-approved integrated vascular surgery residency and fellowship program were exceeding the annual radiation exposure limits. In the present report, we have described our quality improvement project to identify the root causes and implement policies to improve radiation safety education, oversite, and, ultimately, the exposure levels of our trainees. Methods: A committee of faculty, fellows, radiology nurses, and radiation safety officers from each of the programs affiliated hospitals convened to identify the potential root causes of the increased radiation exposure and potential modifiable actions. The radiation exposure reports for postgraduate year 4 to 7 trainees were evaluated before and after the interventions. Results: Excessive radiation exposure was found to be more prevalent than anticipated, with multiple trainees surpassing the annual exposure limits. The committee classified the factors at play and interventions into four categories: policies and procedures, curriculum, environment, resources, and equipment. The multisite status of our program was a key factor associated with the increased radiation exposure. In addition, we found that excessive radiation levels were occurring primarily at a single hospital site. After the interventions, the monthly average levels at this site had decreased considerably from 936 mrem to 272 mrem. Conclusions: We found it alarming that the safety policies in place at vascular residency and fellowship programs were inadequate in securing the safety of their trainees. We found interventions such as inventorying and ensuring the availability of safety equipment, hands-on instruction to complement traditional didactics, lowering the default frame rates, and converting to real-time dosimetry to be effective measures for reducing radiation exposure.
