Variations in Resources Among Radiation Oncology Residency Programs in the United States.

The purpose of this research was to assess the existing variations in the residency training resources among radiation oncology (RO) residency programs in the United States. We queried each residency program website and Fellowship Residency Electronic Interactive Data Access System website (www.freida.ama-assn.org) to obtain information on faculty and available treatment modalities. The data were continuously updated, most recently as of April 30, 2019. A total of 94 RO residency programs were identified during the academic year 2018-2019, and data were collected. The median number of attending physicians was 13 (range, 4 -71). The median number of physicists and biologists were 9 and 3, respectively. The conventional techniques, including 3 dimensional conformal radation therapy, intensity modulated radiation therapy, electron therapy, and stereotactic body radiation therap/stereotactic radiosurgery, were available in all residency programs. In terms of specialized external beam radiation therapy machines, gamma knife, CyberKnife, and magnetic resonance imaging (MRI) linear accelerator were available in 49 (52%), 21(22%), and 7 (8%) programs, respectively. Only 19 programs (20%) had in-house proton therapy availability; however, 37 programs (39%) offered proton therapy training via resident rotation at an affiliated institution. Prostate, gynecologic, and breast brachytherapy were available in 81 (86%), 82 (87%), and 58 (62%) programs, respectively. Eighty-one (86%) programs reported to have high dose rate, and only 20 (21%) programs had low dose rate brachytherapy. Our study found that marked variations exist among RO residency programs in the United States during academic year 2018-2019 and will serve as a baseline for future intervention.
