BackgroundSince the start of the COVID-19 pandemic, the number of digital resources available for medical students (MS) interested in radiation oncology (RO) has increased. Here, we evaluated the utility of webinars focused on educating MS about the RO residency application process.MethodsThe American College of Radiation Oncology hosted webinars in 2021 and 2022 prior to the Electronic Residency Application Service (ERAS) application deadline. For each webinar, program directors gave short presentations about the ERAS application, interviews, and program ranking, and concluded with question and answer session. Participant demographics were collected using live poll questions and understanding was assessed using a Likert scale (range 1 [no, not at all] to 4 [yes, definitely]). Recordings were available online for asynchronous viewing. Differences between groups were assessed using Chi-square statistics.ResultsBetween both webinars, there were a total of 69 participants and 170 asynchronous views. A total of 86% and 71% of participants answered the demographics and understanding questions, respectively. The majority attended medical school within the US (75%), were in their third/fourth year (70%), graduating with an M.D. degree (88%), and planned to apply to RO residency (78%). In terms of baseline knowledge of the application process, 49% believed they knew "a lot," while 51% believed they knew "a little" or "nothing." The majority of participants noted the webinar improved their understanding of the general application process (mean 3.80), the ERAS application (mean 3.65), and the interview process (mean 3.90). For a subset of participants (n=39), survey results were stratified by baseline understanding of the application process ("a little" versus "a lot"). Compared to participants who knew "a lot" about the application process, those that knew "a little" about the process reported higher scores in general understanding (mean 3.80 versus 3.60), ERAS application (mean 3.72 versus 3.50), and interview process (mean 3.93 versus 3.8). However, these differences were not statistically significant.DiscussionAs the number of digital resources in RO increases, we must examine whether they meet the needs of their target audience. Webinars can improve MS understanding of the RO residency application process. These webinars were an ideal format to educate MS about this process because they utilized both attending and resident physicians - two sources of information considered highly trustworthy by MS. Given the recent decline in applications to RO, engaging with MS through dedicated webinars warrants continued exploration.
