This retrospective study was approved by our institutional review board. Participants in our study included all graduates from the Mayo Clinic Department of Radiology residency program from 1975 to 2005. Former graduates, their current addresses, and places of employment were identified from departmental archives. The dates of matriculation and graduation and the identities of previous medical schools were obtained for each former trainee using archived departmental data. Authorship of peer-reviewed publications generated before, during, and after the completion of residency was determined using PubMed (National Library of Medicine) search results. The duration of time spent in medical school and residency training was determined from departmental records, whereas the time after graduation was determined by subtracting a predefined date (January 1, 2011) from the graduation date. The mean authorship rate for each training phase (preresidency, residency, and postresidency) was determined by dividing the number of publications by the duration of time (in years) spent in each phase. For the purposes of this report, “subsequent” publications indicates publications during and after residency. Three groups were defined: group 0 (zero publications prior to residency), group 1 (one publication), and group 2 (more than one publication). The academic productivity of each former resident was assessed using the Hirsch index ( h -index) and history of National Institutes of Health (NIH) funding. The h -index was defined by Hirsch (4) as follows: “A scientist has index h if h of his or her N p papers have at least h citations each and the other ( N p − h ) papers have ≤ h citations each.” The h -index was calculated manually for each former resident using the ISI Web of Knowledge database (5) by determining the number of publications generated after matriculation into residency. The NIH grant funding history of each former resident was determined using the NIH tool Research Portfolio Online Reporting Tools Expenditures and Reports (6–8) . The number of awarded grants, grant type, grant award amount, and status as principal investigator were not discriminating factors in this study.

N2 - Rationale and Objectives: Radiology resident selection committees often favor candidates with strong academic potential. The aim of this study was to determine if preresidency academic productivity of current radiologists was predictive of subsequent of future academic performance. Materials and Methods: The academic productivity of all radiology residents trained between 1975 and 2005 at the authors' institution was assessed through identification of their publication histories, National Institutes of Health funding statuses, and Hirsch indexes (h-indexes). These metrics were correlated with numbers of publications generated prior to beginning radiology residency and grouped accordingly (group 0, none prior to residency; group 1, one publication; and group 2, more than one publication). Academic productivity metrics of the different groups were compared using one-way analysis of variance and χ 2 analysis. Spearman's ρ coefficient was used to evaluate correlations between the number of preresidency publications and subsequent productivity. Results: A cohort of 269 residents was included in this study. Group 0 comprised 182 of the 269 residents (68%), while groups 1 and 2 comprised 27 (10%) and 60 (22%) residents, respectively. Rates of subsequent publication, mean h-index, and National Institutes of Health funding statuses were significantly higher in group 2 compared to both groups 0 and 1 (P < .0001 for each metric). Preresidency publication volume was significantly correlated with future publication performance (ρ = 0.3977, P < .0001), mean h-index (ρ = 0.3086, P < .0001), and National Institutes of Health funding status (ρ = 0.4916, P < .0001). Conclusions: Radiology residency candidates with multiple publications are more likely to achieve future academic success compared to candidates with one or zero publications.
