Scholastic Activity Among Radiation Oncology Residents at US Academic Institutions: a Benchmark Analysis

Objective assessment of academic productivity is useful for residency programs. This study aims to analyze the number of publications and Hirsch index (h index) among radiation oncology residents. Names of residents during the 2010 academic year (n = 607) were collected from the Association of Residents in Radiation Oncology 2010 Directory. Number of publications and h index from Jan. 1996 to Feb. 2012 were collected from a bibliographic database (SCOPUS, Elsevier, BV, Amsterdam, NL). Analysis of h index included stratification by gender, residency size, and postresidency private practice or academic employment. Six hundred seven residents, 67 % men and 33 % women, had an overall mean h index of 2.5 ± 3.2. Graduates in academia exhibited a higher mean h index (3.9 ± 0.30) compared to private practice (2.0 ± 0.25; p < 0.01). Gender, residency size, and post-graduate position remained correlates of h index (all p ≤ 0.01). Women had lower mean h index and number of publications than men (2.1 ± 2.3 vs 2.7 ± 3.5, 4.5 ± 5.3 vs 6.2 ± 8.0, respectively; both p < 0.05). However, when stratified by current position (resident, private practice, or academic), there were no significant differences in h index by gender. The mean ± SD h indices for institutions comprising the top 10 % ranged 4.17 ± 3.2–5.25 ± 5.4 while the bottom 10 % ranged 0.0 ± 0.0–0.75 ± 1.4. The h index is a useful metric to assess residents' early dedication to scholarly endeavors. Female radiation oncology residents had fewer total publications and slightly lower h indices, warranting accessible research avenues and environments for future female physician–scientists. The application of the h index provides a reference for medical students, residents, residency program directors, and many others to gauge academic performance and establish appropriate benchmarks.
