@Article{info:doi/10.2196/13345，作者=“Chiang, Austin Lee and Galler Rabinowitz, Loren and Kumar, Akhil and Chan, Walter Wai-Yip”，标题=“机构社交媒体参与与胃肠病学专业排名的关系:队列研究”，期刊=“J Med Internet Res”，年=“2019”，月=“Sep”，日=“06”，卷=“21”，号=“9”，页=“e13345”，关键词=“社交媒体”;推特;背景:患者通常将社交媒体视为收集有关机构和专业人员信息的重要工具。自1990年以来，《美国新闻与世界报道》(USNWR)每年都发布医院和专科科室的排名。目前尚不清楚社交媒体的存在是否与USNWR胃肠病学和胃肠道(GI)外科部门排名有关，或者随着时间的推移，在线存在的变化如何影响部门排名。目的:本研究的目的是确定社交媒体存在是否与USNWR胃肠病学和GI外科科室排名相关，并确定在线存在随时间的变化如何影响科室排名。方法:在控制协变量的情况下，采用Pearson相关系数和多变量分析对2014年USNWR胃肠病学和GI外科排名前30位的机构进行社交媒体存在度评估。然后使用2014年和2016年USNWR排名的数据进行线性和逻辑回归，以评估机构排名或声誉得分与粉丝数量随时间的潜在变化之间的关系。敏感度分析通过评估接受者工作特征曲线下的面积来确定与提高或保持排名相关的追随者阈值，这是通过在7000和12,000追随者标记之间的值对追随者的变化进行二分类来完成的。结果:Twitter关注者数量是地区排名的独立预测因子($\beta$= 0.00004; P<.001) and reputation score ($\beta$=--.00002; P=.03) in 2014. Academic affiliation also independently predicted USNWR division ranking ($\beta$=5.3; P=.04) and reputation score ($\beta$=--7.3; P=.03). Between 2014 and 2016, Twitter followers remained significantly associated with improved or maintained rankings (OR 14.63; 95{\%} CI 1.08-197.81; P=.04). On sensitivity analysis, an 8000 person increase in Twitter followers significantly predicted improved or maintained rankings compared to other cutoffs. Conclusions: Institutional social media presence is independently associated with USNWR divisional ranking and reputation score. Improvement in social media following was also independently associated with improved or maintained divisional ranking and reputation score, with a threshold of 8000 additional followers as the best predictor of improved or stable ranking.
