A controlled, prospective, 2-year cohort observational study was conducted to test whether weekly geriatric questions delivered through Twitter Poll could improve geriatrics knowledge during an internal medicine clerkship for third-year medical students. Pre- and post-rotation test results used a modified University of California, Los Angeles geriatric knowledge test that included questions linked to 26 Association of American Medical Colleges geriatric competencies for medical students. Data were analyzed using a general linear model repeated-measure design and Student t-test. The primary outcome showed that Twitter Poll participants had more than twice the geriatrics knowledge (p = .002) than students who did not use Twitter Poll. Subset analysis showed different test performances according to sex (p = .03), training site (p = .002), and cohort (p = .003). This study is the first demonstration of Twitter Poll efficacy in medical education and raises questions about whether it could be even more effective if linked to spaced timing of didactic content or supported by annotated answers to geriatrics questions.

一项为期 2 年的对照、前瞻性队列观察研究旨在测试通过 Twitter Poll 每周提供老年医学问题是否可以提高医学生内科实习期间的老年医学知识。使用加利福尼亚大学洛杉矶分校的改良版老年医学知识测试来评估轮转前后的测试结果，该测试包括与美国医学协会为医学生制定的 26 项老年医学能力相关的问题。使用一般线性模型重复测量设计和学生 t 检验对数据进行分析。主要结果显示，与未使用 Twitter Poll 的学生相比，Twitter Poll 参与者的老年医学知识多出两倍以上（p =.002）。亚组分析显示，根据性别（p =.03）、培训地点（p =.002）和队列（p =.003），测试表现存在差异。这项研究首次证明了 Twitter Poll 在医学教育中的有效性，并提出了这样一个问题：如果将其与间隔时间的教学内容相关联，或者支持对老年医学问题的注释答案，它是否会更有效。美国老年学会杂志 66:2389-2393, 2018。
