Asynchronous podcast education is a popular supplementary tool, with up to 88% of medical residents reporting its use. Radiation oncology podcasts remain scarce. The authors analyzed the early performance, listenership, and engagement of the first education-specific radiation oncology medical podcast.
Episode data and listener demographics were gathered from Spotify and Apple Podcasts. Episodes were case based, categorized by disease subsite, and reviewed by a board-certified radiation oncologist. Listenership was defined by the number of plays per day (ppd) on unique devices, averaged up to 60 days from publication. Episode engagement was defined as a percentage of plays on unique devices playing >40% of an episode within a single session. Quantitative end points included episode engagement and listenership. Pearson's correlation coefficient calculations were used for analysis.
From July 2022 to March 2023, 20 total episodes had 13,078 total plays over 227 days. The median episode length was 13.8 min (range, 9.2-20.1 min). Listener demographics were as follows: 54.4% men, 44.0% women, 1.3% not specified, and 0.3% nonbinary, with ages 18 to 22 (1%), 23 to 27 (13%), 28 to 34 (58%), 35 to 44 (22%), 45 to 59 (4%), and ≥60 (2%) years. Episodes were played in 53 countries, with the most plays in North America (71.5%), followed by Asia (10.2%), Europe (8.2%), Oceania (8.0%), Africa (1.5%), and South America (0.5%). There was a 585.2% increase in listenership since initiation, with median growth of 46.0% per month. Median listenership and engagement were 11.3 ppd (interquartile range, 10.3-13.8 ppd) and 81.4% (interquartile range, 72.0%-84.2%) for all episodes, respectively. A significant negative relationship between episode length and engagement was observed (r[20] = -0.51, P = .02). There was no statistically significant relationship between ppd and episode length (r[20] = -0.19, P = .42).
The significant rise in listenership, high episode engagement, and large international audience support a previously unmet need in radiation oncology medical education that may be supplemented by podcasts.
异步播客教育是一种流行的补充工具，多达 88%的住院医师报告使用过它。放射肿瘤学播客仍然很少。作者分析了第一个专门针对放射肿瘤学的医学播客的早期表现、收听率和参与度。
从 Spotify 和 Apple Podcasts 收集了剧集数据和听众人口统计数据。剧集是基于案例的，按疾病部位分类，并由一名经过委员会认证的放射肿瘤学家审查。收听率由每天在独特设备上的播放次数（ppd）定义，平均从发布之日起 60 天。剧集参与度定义为在单个会话中播放超过 40%剧集的独特设备播放次数的百分比。定量终点包括剧集参与度和收听率。使用 Pearson 相关系数计算进行分析。
从 2022 年 7 月到 2023 年 3 月，共有 20 集共播放了 13078 次，总时长为 227 天。每集的平均长度为 13.8 分钟（范围为 9.2-20.1 分钟）。听众人口统计数据如下：男性占 54.4%，女性占 44.0%，1.3%未指定，0.3%非二进制，年龄在 18 至 22 岁（1%）、23 至 27 岁（13%）、28 至 34 岁（58%）、35 至 44 岁（22%）、45 至 59 岁（4%）和≥60 岁（2%）。剧集在 53 个国家播放，其中北美播放量最多（71.5%），其次是亚洲（10.2%）、欧洲（8.2%）、大洋洲（8.0%）、非洲（1.5%）和南美洲（0.5%）。自开播以来，收听率增长了 585.2%，每月平均增长率为 46.0%。所有剧集的中位数收听率和参与度分别为 11.3 ppd（四分位间距，10.3-13.8 ppd）和 81.4%（四分位间距，72.0%-84.2%）。观察到剧集长度与参与度之间存在显著的负相关关系（r[20]=-0.51，P=0.02）。剧集长度与收听率之间没有统计学上的显著关系（r[20]=-0.19，P=0.42）。
收听率的显著上升、剧集的高参与度以及大量的国际受众支持了放射肿瘤学医学教育中以前未满足的需求，播客可能会对此进行补充。
