Introduction: Undergraduate research among medical students is essential in the education of future physicians and scientists. This study aimed to evaluate the scientific yield of extracurricular undergraduate research among medical students.
Methods: Medical students at the University of Copenhagen who completed an extracurricular research year between January 2004 and June 2013 were evaluated through a manual search in PubMed MEDLINE. The primary focus was the number of peer-reviewed, published articles.
Results: Of the 363 included students, 3.1% did their research in 2004-2005 compared with 46.5% in 2012-2013. After three years, 70.4% of the students had published a peer-reviewed article, and of all the 363 students, 36.5%, had published as a first author. In total, 87.7% had a medical specialty as their research area versus a surgical specialty. Most students were involved in cardiology (14.1%). Cardiology was also associated with the greatest scientific yield with a median number of 0.8 publications per year after the students concluded their undergraduate research period. Three or more years after concluding their undergraduate research, 32.8% of the students had continued with research in the context of a PhD programme.
Conclusion: Overall, the number of medical students who engaged in extracurricular research followed an increasing trend, and more than two-thirds of these students published a peer-reviewed paper within three years. Cardiology was the most popular specialty and also the specialty with the greatest scientific yield. A third of the undergraduate research students continued doing research in the context of a PhD programme.
