Abstract

BACKGROUND

We studied the scientific yield of the medical PhD program at all Danish Universities.

METHODS

We undertook a retrospective observational study. Three PhD schools in Denmark were included in order to evaluate the postdoctoral research production over more than 18 years through individual publications accessed by PubMed.

RESULTS

A total of 2686 PhD-graduates (1995-2013) with a medical background were included according to registries from all PhD schools in Denmark. They had a median age of 35 years (interquartile range (IQR), 32-38) and 53 % were women at the time of graduation. Scientific activity over time was assessed independently of author-rank and inactivity was measured relative to the date of graduation. Factors associated with inactivity were identified using multivariable logistic regression. 88.6 % of the PhD theses were conducted in internal medicine vs. 11.4 % in surgery. During follow-up (median 6.9 years, IQR 3.0-11.7), PubMed data searches identified that 87 (3.4 %) of the PhD graduates had no publication after they graduated from the PhD program, 40 % had 5 or less, and 90 % had 30 or less. The median number of publications per year after PhD graduation was 1.12 (IQR 0.61-1.99) papers per year. About 2/3 of the graduates became inactive after 1 year and approximately 21 % of the graduates remained active during the whole follow-up. Female gender was associated with inactivity: adjusted odds ratio 1.59 (95 % confidence interval 1.24-2.05).

CONCLUSIONS

The scientific production of Danish medic PhD-graduates was mainly produced around the time of PhD-graduation. After obtaining the PhD-degree the scientific production declines suggesting that scientific advance fails and resources are not harnessed.

摘要

背景

我们研究了丹麦所有大学医学博士项目的科研产出情况。

方法

我们进行了一项回顾性观察研究。纳入了丹麦的三所博士学院，以便通过PubMed获取的个人出版物来评估超过18年的博士后研究成果。

结果

根据丹麦所有博士学院的登记记录，共纳入了2686名具有医学背景的博士毕业生（1995 - 2013年）。他们毕业时的中位年龄为35岁（四分位间距（IQR），32 - 38岁），53%为女性。随着时间推移的科研活动是独立于作者排名进行评估的，不活跃情况是相对于毕业日期来衡量的。使用多变量逻辑回归确定与不活跃相关的因素。88.6%的博士论文是在内科进行的，而外科为11.4%。在随访期间（中位时间6.9年，IQR 3.0 - 11.7年），通过PubMed数据检索发现，87名（3.4%）博士毕业生毕业后没有发表任何论文，40%的人发表了5篇或更少的论文，90%的人发表了30篇或更少的论文。博士毕业后每年的出版物中位数为每年1.12篇（IQR 0.61 - 1.99篇）。约2/3的毕业生在1年后变得不活跃，约21%的毕业生在整个随访期间一直保持活跃。女性与不活跃相关：调整后的优势比为1.59（95%置信区间1.24 - 2.05）。
