We aimed to investigate the impact of taking dedicated time for research (DTR) during training and/or getting a PhD on subsequent career achievements of US academic cardiothoracic surgeons.
Online resources (institutional Web sites, CTSNet, Scopus, NIH RePORTER) were queried to collect training information (timing of medical school/residency/fellowship graduation, DTR, PhD) and academic metrics (publications, citations, research funding) for 694 academic cardiothoracic surgeons practicing at 56 premiere US institutions.
Excluding missing data, 464 (75 %) surgeons took DTR and 156 (25 %) did not; 629 (91 %) were MD only and 65 (9 %) also had a PhD. DTR was associated with higher number of ongoing publications (~5.6/year vs. ~3.8/year), with no difference for accrued number of total citations. History of DTR was more prevalent among surgeons with versus without NIH funding (87 vs. 71 %; p < 0.001), but no difference was seen across academic ranks and among those who were division/department chiefs. No overall increase in publications/citations, academic rank advancement, NIH funding, or leadership roles was found for those with a PhD.
Among cardiothoracic surgeons, devoting time during the training years exclusively to research might be associated with higher career-long academic productivity in terms of annual number new publications and ability to get NIH funding, but without significant impact in terms of academic rank or institutional role advancement. No significant difference was found between those with versus without a PhD in terms of career-long number of publications/citations, academic rank, NIH funding, or leadership role, even though sample size might have been insufficient to identify any such potential difference.
我们旨在研究在培训期间抽出专门时间进行研究（DTR）和/或获得博士学位对美国心胸外科医生后续职业成就的影响。
查询在线资源（机构网站、CTSNet、Scopus、美国国立医学图书馆科研项目在线报告工具），收集694名在美国56家顶尖机构执业的心胸外科医生的培训信息（医学院/住院医师培训/专科培训毕业时间、DTR、博士学位）和学术指标（发表论文数量、引用次数、研究经费）。
排除缺失数据后，464名（75%）外科医生进行了DTR，156名（25%）未进行；629名（91%）仅拥有医学博士学位，65名（9%）还拥有博士学位。DTR与更多的在研论文数量相关（约每年5.6篇对约每年3.8篇），总引用次数累计无差异。有DTR经历在获得美国国立卫生研究院资助的外科医生中比未获得资助的外科医生中更普遍（87%对71%；p<0.001），但在不同学术职级以及科室主任中未发现差异。拥有博士学位者在论文发表/引用次数、学术职级晋升、美国国立卫生研究院资助或领导职位方面未发现总体增加。
在心胸外科医生中，在培训期间专门投入时间进行研究可能与较高的终身学术产出相关，表现为每年新发表论文数量和获得美国国立卫生研究院资助的能力，但对学术职级或机构角色晋升没有显著影响。在终身发表论文/引用次数、学术职级、美国国立卫生研究院资助或领导角色方面，拥有博士学位者与未拥有博士学位者之间未发现显著差异，尽管样本量可能不足以识别任何此类潜在差异。
