[Radiology residency training during the COVID-19 pandemic : Conception and evaluation of a three-phase online-based teaching concept].

The coronavirus pandemic has posed major challenges to clinical training. Innovative and interactive concepts are needed to maintain training for residents even in times of contact restrictions and distance rules. Training concepts for residents are underrepresented in the current literature. We present an innovative online-based training concept for radiology residents in our department, based on a tripartite design; independent case preparation where residents refer to existing knowledge is followed by a case discussion and specific questions and feedback from the participating senior physicians. A questionnaire-based evaluation of the training concept was carried out after 12 months. We found that participants rated the training concept positively when it came to difficulty, representativeness of clinical work and relevance for specialist training. The questionnaire responses also provided insights into the desired duration, the selection of imaging modalities, and frequency of the concept in the future. All respondents stated that they had benefited from the format. Online-based concepts can therefore be a relevant contribution to the clinical training of residents and represent an adequate alternative to or extension of analog concepts.
