An informal needs assessment and lack of a national standardized curriculum suggest that there is tremendous variability in the formal teaching of radiation oncology resident throughout the USA. The goal of this study was to characterize formal radiation oncology resident education, in order to identify knowledge gaps and areas for improvement. We developed a 14-item survey consisting of the following domains: program characteristics, teaching faculty, formal teaching time, instructional approaches for formal teaching, curricular topics, and satisfaction with didactics. All 91 accredited US-based radiation oncology program directors received an invitation to complete the survey anonymously by email. Twenty-four (26% response rate) program directors responded. Programs used a variety of instructional methods; all programs reported using lecture-based teaching and only a minority using simulation (38%) or flipped classroom techniques (17%). Other than PowerPoint, the most common electronic resource utilized was quizzing/polling (67%), webinar (33%), and econtour.org (13%). The lack of a national, standardized, radiation oncology residency didactic curriculum promotes variability and insufficiency in resident training. Themes for improvement were diversity in didactic topics, incorporation of evidence-based teaching practices, increased faculty involvement, and sharing of resources across programs. Development of a national curriculum and increased electronic resource sharing may help address some of these areas of improvement.

非正式的需求评估和缺乏国家标准化课程表明，美国各地放射肿瘤学住院医师的正式教学存在巨大差异。本研究的目的是描述正规放射肿瘤学住院医师教育的特点，以确定知识差距和需要改进的领域。我们制定了一项包含以下领域的 14 项调查：课程特点、教师队伍、正式教学时间、正式教学的教学方法、课程主题和教学满意度。所有 91 位经过认证的美国放射肿瘤学项目主管都收到了通过电子邮件匿名完成调查的邀请。二十四位（26% 的回应率）项目主管做出了回应。课程使用了多种教学方法；所有项目都报告使用基于讲座的教学，只有少数项目使用模拟 (38%) 或翻转课堂技术 (17%)。除了 PowerPoint，最常使用的电子资源是测验/投票 (67%)、网络研讨会 (33%) 和 econtour.org (13%)。缺乏国家标准化的放射肿瘤学住院医师教学课程导致住院医师培训的多样性和不足。改进的主题是教学主题的多样性、循证教学实践的结合、教师参与的增加以及跨项目的资源共享。开发国家课程和增加电子资源共享可能有助于解决其中一些需要改进的领域。最常使用的电子资源是测验/投票 (67%)、网络研讨会 (33%) 和 econtour.org (13%)。缺乏国家标准化的放射肿瘤学住院医师教学课程导致住院医师培训的多样性和不足。改进的主题是教学主题的多样性、循证教学实践的结合、教师参与的增加以及跨项目的资源共享。开发国家课程和增加电子资源共享可能有助于解决其中一些需要改进的领域。最常使用的电子资源是测验/投票 (67%)、网络研讨会 (33%) 和 econtour.org (13%)。缺乏国家标准化的放射肿瘤学住院医师教学课程导致住院医师培训的多样性和不足。改进的主题是教学主题的多样性、循证教学实践的结合、教师参与的增加以及跨项目的资源共享。开发国家课程和增加电子资源共享可能有助于解决其中一些需要改进的领域。改进的主题是教学主题的多样性、循证教学实践的结合、教师参与的增加以及跨项目的资源共享。开发国家课程和增加电子资源共享可能有助于解决其中一些需要改进的领域。改进的主题是教学主题的多样性、循证教学实践的结合、教师参与的增加以及跨项目的资源共享。开发国家课程和增加电子资源共享可能有助于解决其中一些需要改进的领域。
