To complement traditional citation-based metrics, which take years to accrue and indicate only academic attention, academia has begun considering altmetrics or alternative metrics, which provide timely feedback on an article's impact by tracking its dissemination via nontraditional outlets, such as blogs and social media, across audiences. This article describes altmetrics and examines altmetrics attention, outlets used, and top article characteristics for health professions education (HPE) research.
Using Altmetric Explorer, a tool to search altmetrics activity, the authors searched for HPE articles that had at least one altmetrics event (e.g., an article was tweeted or featured in a news story) between 2011 and 2015. Retrieved articles were analyzed using descriptive statistics. In addition, the 10 articles with the highest Altmetric Attention Scores were identified and their key characteristics extracted.
The authors analyzed 6,265 articles with at least one altmetrics event from 13 journals. Articles appeared in 14 altmetrics outlets. Mendeley (161,470 saves), Twitter (37,537 tweets), and Facebook (1,650 posts) were most popular. The number of HPE articles with altmetrics attention increased 145%, from 539 published in 2011 to 1,321 in 2015. In 2015, 50% or more of the articles in 5 journals received altmetrics attention. Themes for articles with the most altmetrics attention included social media or social networking; three such articles were written as tips or guides.
Increasing altmetrics attention signals interest in HPE research and the need for further investigation. Knowledge of popular and underused outlets may help investigators strategically share research for broader dissemination.
为了补充传统的引文计量指标，这些指标需要数年时间积累，只能反映学术关注度，学术界开始考虑使用替代计量指标或另类计量指标，通过跟踪文章在非传统渠道（如博客和社交媒体）上的传播情况，及时反馈文章的影响力。本文描述了替代计量指标，并考察了健康职业教育（HPE）研究的替代计量指标关注度、使用的渠道以及热门文章的特征。
使用 Altmetric Explorer 这一搜索替代计量指标活动的工具，作者搜索了 2011 年至 2015 年间至少有一个替代计量指标事件（例如，文章被推特转发或新闻报道引用）的 HPE 文章。使用描述性统计方法对检索到的文章进行分析。此外，确定了 10 篇具有最高 Altmetric 关注度得分的文章，并提取了它们的关键特征。
作者分析了来自 13 种期刊的 6265 篇至少有一个替代计量指标事件的文章。文章出现在 14 个替代计量指标渠道中。Mendeley（161470 次保存）、Twitter（37537 条推文）和 Facebook（1650 条帖子）最为流行。具有替代计量指标关注度的 HPE 文章数量增加了 145%，从 2011 年的 539 篇增加到 2015 年的 1321 篇。在 2015 年，5 种期刊中有 50%或更多的文章获得了替代计量指标关注度。具有最多替代计量指标关注度的文章主题包括社交媒体或社交网络；其中三篇文章是作为技巧或指南撰写的。
替代计量指标关注度的增加表明了对 HPE 研究的兴趣，需要进一步研究。了解流行和未充分利用的渠道可能有助于研究人员更具战略性地分享研究成果，以实现更广泛的传播。
