The National Institutes of Health (NIH) recently developed the relative citation ratio (RCR), calculated as article citations benchmarked to NIH-funded publications in the same field. Here, we characterized the scholarly impact of academic cardiothoracic (CT) surgeons and their research using the RCR.
Using a database of 992 CT surgeons, we calculated the RCR for all articles published by each surgeon since 1980 using the NIH iCite database. All data were collected from publicly available online sources. Data are presented as median (interquartile range) or as odds ratios (ORs) for multivariable logistic regression analysis.
Where RCR 1.00 indicates equal impact as an NIH-funded publication, the RCR among all 37,402 CT surgery articles was 0.84 (0.33-1.83) and the RCR among NIH-funded CT surgery articles was 1.07 (0.53-2.17). CT surgeons exhibited a career median RCR of 0.82 (0.54-1.13) and maximum RCR of 6.20 (3.04-13.57). Predictors of career median RCR >1.00 included female gender (OR 2.23, P = 0.001), thoracic subspecialization (OR 2.50, P < 0.001), full professor rank (OR 1.89, P = 0.001), and NIH funding (OR 1.75, P = 0.001). Predictors of career maximum RCR >50th percentile among CT surgeons included male gender (OR 1.87, P = 0.030), thoracic subspecialization (OR 2.05, P < 0.001), full professor rank (OR 4.89, P < 0.001), NIH funding (OR 3.17, P < 0.001), and career duration (OR 1.03, P = 0.002).
We present the first assessment of the NIH-validated RCR for academic CT surgery. CT surgery research is highly impactful, although gender disparities persist with respect to the highest-impact research of our specialty.
美国国立卫生研究院（NIH）最近开发了相对引用率（RCR），其计算方法是将文章引用次数与同一领域由NIH资助的出版物进行基准对比。在此，我们使用RCR对心胸外科（CT）学术外科医生及其研究的学术影响力进行了特征描述。
利用一个包含992名CT外科医生的数据库，我们使用NIH iCite数据库计算了自1980年以来每位外科医生发表的所有文章的RCR。所有数据均从公开可用的在线资源收集。数据以中位数（四分位间距）或多变量逻辑回归分析的优势比（OR）表示。
RCR为1.00表示与NIH资助的出版物具有同等影响力，在所有37402篇CT外科手术文章中，RCR为0.84（0.33 - 1.83），在由NIH资助的CT外科手术文章中，RCR为1.07（0.53 - 2.17）。CT外科医生的职业RCR中位数为0.82（0.54 - 1.13），最高RCR为6.20（3.04 - 13.57）。职业RCR中位数>1.00的预测因素包括女性性别（OR 2.23，P = 0.001）、胸科亚专业（OR 2.50，P < 0.001）、正教授职称（OR 1.89，P = 0.001）和NIH资助（OR 1.75，P = 0.001）。CT外科医生中职业最高RCR>第50百分位数的预测因素包括男性性别（OR 1.87，P = 0.030）、胸科亚专业（OR 2.05，P < 0.001）、正教授职称（OR 4.89, P < 0.001）、NIH资助（OR 3.17，P < 0.001）和职业时长（OR 1.03，P = 0.002）。
我们首次对经NIH验证的CT外科学术RCR进行了评估。CT外科手术研究具有高度影响力，尽管在我们专业领域的最高影响力研究方面性别差异仍然存在。
