Social media microblogging has made major inroads in physician education and information exchange. The authors evaluated their early experience with Twitter "tweet chat" sessions as a medium to expand the reach and audience of a peer-reviewed radiology journal.
The authors analyzed Twitter activity metadata tagged with the #JACR hashtag from the first 6 tweet chat sessions sponsored and promoted by JACR. The assessment included multiple metrics: radiologist versus nonradiologist session participants, individual tweets, tweets with embedded web links, common words, retweets, and impressions. We correlated Twitter metrics with temporally related journal website activity.
Each session generated a mean of 444 ± 172 tweets contributed by a mean of 33 ± 14 participants (45.4% nonradiologists) and resulted in a mean of 1,163,712 ± 441,971 impressions. Per session, a mean of 19 ± 7.6 tweets contained web links, and 138 ± 35.6 tweets were retweets. Monthly journal website article views increased from 31,220 to 41,017 (+31.4%), journal website visits increased from 9,192 to 11,539 (+25.5%), and unique visitors increased from 7,368 to 8,841 (+20%). Since JACR tweet chats were initiated, mean monthly journal website visits and page views per month directly from twitter.com increased from 24 to 101 (+321%) and from 38 to 159 (+318%), respectively.
Early experience with JACR tweet chats demonstrates that organizing Twitter microblogging activities around topics of general interest to their target readership bears the potential for medical journals to increase their audiences and reach.
社交媒体微博在医学教育和信息交流方面取得了重大进展。作者评估了他们早期使用Twitter“推文聊天”会话作为一种媒介来扩大同行评审放射学杂志的影响力和受众群体的经验。
作者分析了由《美国放射学会杂志》（JACR）发起并推广的前6次推文聊天会话中带有#JACR标签的Twitter活动元数据。评估包括多个指标：放射科医生与非放射科医生会话参与者、个人推文、带有嵌入式网页链接的推文、常用词汇、转发推文以及展示量。我们将Twitter指标与时间相关的期刊网站活动进行了关联。
每次会话平均产生444 ± 172条推文，平均由33 ± 14名参与者贡献（45.4%为非放射科医生），平均展示量为1,163,712 ± 441,971次。每次会话平均有19 ± 7.6条推文包含网页链接，138 ± 35.6条推文被转发。期刊网站每月文章浏览量从31,220增加到41,017（增长31.4%），期刊网站访问量从9,192增加到11,539（增长25.5%），独立访客从7,368增加到8,841（增长20%）。自JACR推文聊天启动以来，直接来自twitter.com的期刊网站每月平均访问量和页面浏览量分别从24增加到101（增长321%）和从38增加到159（增长318%）。
JACR推文聊天的早期经验表明，围绕其目标读者普遍感兴趣的主题组织Twitter微博活动，医学期刊有潜力增加其受众群体和影响力。
