The Thoracic Surgery Social Media Network (TSSMN) represents a collaborative effort of leading journals in cardiothoracic surgery to highlight publications via social media, specifically Twitter. We conducted a prospective randomized trial to determine the effect of scheduled tweeting on nontraditional bibliometrics of dissemination.
A total of 112 representative original articles (2017-2018) were selected and randomized 1:1 to an intervention group to be tweeted via TSSMN or a control (non-tweeted) group. Four articles per day were tweeted by TSSMN delegates for 14 days. Primary endpoints included change in article-level metrics (Altmetric) score pre-tweet and post-tweet compared with the control group. Secondary endpoints included change in Twitter analytics day 1 post-tweet and day 7 post-tweet for each article compared with baseline.
Tweeting via TSSMN significantly improved article Altmetric scores (pre-tweet 1 vs post-tweet 8; P < .001), Mendeley reads (pre-tweet 1 vs post-tweet 3; P < .001), and Twitter impressions (day 1 post-tweet 1599 vs day 7 post-tweet 2296; P < .001). Subgroup analysis demonstrates that incorporating photos into the tweets trended toward increased link clicks to the full-text article (P = .08) whereas tweeting at 1 pm Eastern Standard Time and 9 pm Eastern Standard Time generated the highest and lowest audience reach (P = .022), respectively. Articles published in adult cardiac surgery achieved the highest change in Altmetric score (P = .028) and Mendeley reads (P = .028), and were more likely to be retweeted (P = .042) than were those published on education, general thoracic surgery, and congenital surgery.
Social media highlights of scholarly literature via TSSMN Twitter activity improves article Altmetric scores, Mendeley reads, and Twitter analytics, with dissemination to a greater audience.
胸外科社交媒体网络（TSSMN）代表了心胸外科学领域领先期刊的合作努力，旨在通过社交媒体（特别是 Twitter）突出出版物。我们进行了一项前瞻性随机试验，以确定定期推文对非传统传播文献计量学的影响。
共选择了 112 篇具有代表性的原创文章（2017-2018 年），并将其随机分为干预组（通过 TSSMN 进行推文）和对照组（未推文），每组各 56 篇。每天由 TSSMN 代表发布 4 篇文章，持续 14 天。主要终点包括与对照组相比，推文前和推文后文章层面指标（Altmetric）评分的变化。次要终点包括与基线相比，推文后第 1 天和第 7 天每条文章的推文后 Twitter 分析数据的变化。
通过 TSSMN 推文显著提高了文章的 Altmetric 评分（推文前 1 分，推文后 8 分；P <.001）、Mendeley 阅读量（推文前 1 分，推文后 3 分；P <.001）和推文后的 Twitter 印象数（推文后第 1 天 1599 次，推文后第 7 天 2296 次；P <.001）。亚组分析表明，在推文中加入照片有助于增加对全文文章的链接点击量（P =.08），而在东部标准时间下午 1 点和东部标准时间晚上 9 点推文则分别产生了最高和最低的受众覆盖范围（P =.022）。发表在成人心脏手术方面的文章在 Altmetric 评分（P =.028）和 Mendeley 阅读量（P =.028）方面的变化最大，并且比发表在教育、普通胸外科和先天性外科方面的文章更有可能被转发（P =.042）。
通过 TSSMN Twitter 活动突出显示学术文献可以提高文章的 Altmetric 评分、Mendeley 阅读量和 Twitter 分析数据，并将其传播给更多的受众。
