Abstract

BACKGROUND

Studies have shown that publication of work during medical school and residency is associated with higher numbers of later publications and citations of published research. However, it is unknown whether this association exists for non-PhD physician-scientists and whether the association persists later into their careers.

METHODS

We extracted publication records from the curricula vitae (CVs) of 102 corresponding authors of articles published in 2008 in the New England Journal of Medicine and JAMA, and obtained those authors' citation records from Web of Science. We used regression models to examine the association between time of first publication and later publication and citation rates for the entire postgraduate career and a recent 2-year period.

RESULTS

After adjusting for time since medical school graduation, sex, location of medical school (United States or not United States), and additional non-PhD degrees, we found that authors who first published before graduating from medical school had a greater mean number of publications after medical school and during the period from 2006 to 2007 (164 and 28, respectively) than those who first published during the 5 years afterward (111 and 19, respectively) and those who first published more than 5 years after graduation (59 and 13, respectively). Similarly, authors who first published before graduating from medical school had a greater mean number of citations of their published work since graduation and of publications from 2006 to 2007 (4634 and 333, respectively) than those who first published during the 5 years afterward (2936 and 183, respectively) and those who first published more than 5 years after graduation (1512 and 143, respectively).

CONCLUSIONS

Early publication is associated with higher numbers of publications and more citations of published research among non-PhD physician-scientists. This association persists well into a researcher's career.

摘要

背景

研究表明，在医学院和住院医师培训期间发表作品与后期发表的作品数量更多以及已发表研究获得的引用次数更多相关。然而，尚不清楚这种关联是否存在于非博士医师科学家群体中，以及这种关联在他们职业生涯后期是否仍然存在。

方法

我们从2008年发表在《新英格兰医学杂志》和《美国医学会杂志》上的文章的102位通讯作者的简历中提取了发表记录，并从科学网获取了这些作者的引用记录。我们使用回归模型来研究首次发表时间与整个研究生涯以及最近两年期间后期发表率和引用率之间的关联。

结果

在校正自医学院毕业以来的时间、性别、医学院所在地（美国或非美国）以及其他非博士学位后，我们发现，在医学院毕业前首次发表的作者在医学院毕业后以及2006年至2007年期间的平均发表数量（分别为164篇和28篇）高于在毕业后5年内首次发表的作者（分别为111篇和19篇）以及毕业后5年以上首次发表的作者（分别为59篇和13篇）。同样，在医学院毕业前首次发表的作者自毕业以来以及2006年至2007年期间其已发表作品的平均被引用次数（分别为4634次和333次）高于在毕业后5年内首次发表的作者（分别为2936次和183次）以及毕业后5年以上首次发表的作者（分别为1512次和143次）。
