Publication productivity of pathology residents: a nationwide cohort study in France.

The publication productivity of residents has been reported in various specialties, mainly in North America, but never in pathology. In France, pathology residents must defend a medical thesis to obtain the title of medical doctor and to practice medicine. The aim of this study was to assess the thesis performance and publication output of a nationwide cohort of pathology residents from six graduating classes in France. Among 231 theses, 110 (48%) resulted in publications, of which 95% were original articles (OA) and 74% were resident first-author publications. The median impact factor (IF) was 3.6 (2.8-5.9). During residency and in the 4 years following defense, residents published a median of 5 (2-10) total publications, 2 (1-6) OA, and 1 (0-3) first-author manuscripts. Among 1849 publications, 822 (44%) were first, second, or last-authored by residents. The median IF of the 362 (20%) OA published as first, second, and last author was 3.1 (2.4-5), 3.3 (2.2-5.2), and 3.2 (0.9-3.3), respectively. Only 44% of these OA were indexed in the pathology category according to Web of Science, with Virchows Arch being the most common journal. Residents who published their medical thesis had a higher median number of total publications, as well as first- and last-author OA (p = 0.0005, p = 0.001 and p = 0.007, respectively). The publication record of pathology residents goes beyond the field of pathology, with most contributions to non-pathology journals. The mandatory medical thesis provides a valuable opportunity for pathology residents to engage in research and may be the first step towards publication productivity.
