(1) Background: Research productivity is a mandatory component of Canadian radiation oncology (RO) resident training. To our knowledge, Canadian RO resident research publication productivity has not previously been analysed. (2) Methods: We compiled a 12-year database of RO residents in Canadian training programs who completed residency between June 2005 and June 2016. Resident names and dates of training were abstracted from provincial databases and department websites and were used to abstract data from PubMed, including training program, publication year, journal, type of research, topic and authorship position. Residents were divided into four time periods and the linear trend test evaluated publication rates over time. Univariable and multivariable logistic regression analyses were performed to identify authorship predictors. (3) Results: 227 RO residents representing 363 publications were identified. The majority were first-author publications (56%) and original research (77%). Overall, 82% of first-author, and 80% of any-author articles were published in resident year 4 or higher. Mean number of publications for first-author and any-author positions increased significantly over time (p = 0.016 and p = 0.039, respectively). After adjusting for gender and time period, large institutions (> 3 residents per year) trended toward associations with more first-author publications (odds ratio (OR): 2.44; p = 0.066) and more any-author publications (OR: 2.49; p = 0.052). No significant differences were observed by gender. (4) Conclusions: Canadian RO resident publication productivity nearly doubled over a 12-year period. The majority of publications are released in the last 2 years of residency, and larger residency programs may be associated with more publications. These findings serve as a baseline as programs transition to Competency Based Medical Education (CBME).

加拿大放射肿瘤学居民的研究生产力：时间趋势分析

(1) 背景：研究生产力是加拿大放射肿瘤学 (RO) 住院医师培训的强制性组成部分。据我们所知，之前没有对加拿大 RO 常驻研究发表生产力进行过分析。(2) 方法：我们对2005年6月至2016年6月期间完成居住的加拿大培训项目的RO居民进行了12年的数据库。从省级数据库和部门网站中提取居民姓名和培训日期，并用于从PubMed，包括培训计划、出版年份、期刊、研究类型、主题和作者职位。居民被分为四个时间段，线性趋势测试评估了一段时间内的发表率。进行单变量和多变量逻辑回归分析以确定作者身份预测因素。(3) 结果：确定了代表 363 份出版物的 227 名 RO 居民。大多数是第一作者出版物 (56%) 和原创研究 (77%)。总体而言，82% 的第一作者和 80% 的任意作者文章发表在第 4 年或更高级别。随着时间的推移，第一作者和任何作者职位的平均出版物数量显着增加（分别为 p = 0.016 和 p = 0.039）。在调整性别和时间段后，大型机构（每年> 3 名居民）倾向于与更多的第一作者出版物（比值比 (OR)：2.44；p = 0.066）和更多的任意作者出版物（OR：2.49； p = 0.052）。没有观察到性别的显着差异。(4) 结论：加拿大 RO 居民出版生产力在 12 年期间几乎翻了一番。大多数出版物是在最近 2 年的驻留期间发布的，更大的驻留项目可能与更多的出版物相关联。这些发现可作为项目过渡到基于能力的医学教育 (CBME) 的基线。
