Bibliometric Review of Medical Student Research Before Matching Integrated Vascular Surgery

Background: Research output is one element of a multifactorial process that residency programs consider when evaluating applicants. However, there are minimal data assessing research productivity on admittance into research-oriented integrated vascular surgery residency (RO-IVSR) programs. The purpose of this study was to evaluate the association of peer-reviewed research and the RO-IVSR match process. Material and methods: Vascular surgery residents who matched into an RO-IVSR in 2015-2017 were divided into those matching an RO-IVSR top 10 program versus other. Total publications, first authorships, and type of research were compared between groups. Mann-Whitney U-tests were then performed between discrete levels of research productivity (0-1 versus ≥2 publications) to detect differences in ability to match a top 10 program. Results: One hundred and fifty-eight residents published a total of 214 original research articles (83%), 26 case reports (10%), and 19 systematic reviews (7%). There were 66 first authorships (25%). Median total publications at RO-IVSR top 10 versus other programs were 2 versus 1 (P < 0.01). Top 10 IVSR had a significant difference in median publications for all other research categories. The ability to match into a top 10 program by discrete levels of research productivity at 0-1 versus 2+ showed significance (P < 0.05) in all research categories, including total publications, first authorships, and H-index. Conclusions: There was significantly higher research productivity among medical students who matriculate to top 10 IVSR programs. Furthermore, having 2 or more publications significantly increased the likelihood of attending a top 10 program. Thus, top programs likely use an applicants’ research productivity as a distinct qualification category and a marker of future success.
