Clinical Physics Boot Camp for Radiation Oncology Residents: A Pilot Study

Abstract

The physics curriculum is a source of anxiety both for medical students considering radiation oncology (RO) as a possible career and for current residents facing the physics boards. To improve the orientation process for residents and medical students, we created a physics boot camp using clinically relevant patient vignettes to teach physics fundamentals. The initial boot camp was a week-long program of 1.5 to 2 hours daily, with each day consisting of a didactic session and hands-on laboratory. Boot camp topics covered included physics fundamentals, electron treatments, photon treatments, brachytherapy, and urgent clinical setups. Learners completed pre- and postsurveys, where each rated their knowledge and comfort level with RO workflow on a 5-point scale. Learners also completed daily knowledge-based assessments testing the information presented before and after these daily sessions. A total of 10 participants were included in the initial boot camp: 8 residents and 2 medical students. A repeat, single-day, multi-institutional boot camp a year later included 5 of the original resident participants. Participant scores were paired for analysis using student t tests. For the initial boot camp, all participants reported significantly increased confidence in the physics aspects of the RO workflow (mean 3.24 vs 4.18; P = .0023). However, when comparing those self-assessment scores from participants with more than a year of physics background to those earlier in their training, only the early training participants’ scores remained significant (advanced learners: mean 4.0 vs 4.38, P = .129; early learners: mean 2.66 vs 4.02, P = .0025). All participants had improved scores on their knowledge-based assessments (mean 74% vs 89%; P = .0001), which remained statistically significant for both early learners (mean 68% vs 87%; P = .0005) and advanced learners (mean 84% vs 93%; P = .0447). For repeat participants, preboot camp knowledge showed continued improvement (mean 61% vs 79%; P = .049) at 1 year. A formal physics boot camp orientation improves both resident comfort level and knowledge base with clinical physics, with participants early in their training deriving the greatest benefit.
