Relationship Between Citation-Based Scholarly Activity of United States Radiation Oncology Residents and Subsequent Choice of Academic Versus Private-Practice Career.

Abstract

To assess h-index data and their association with radiation oncology resident choice of academic versus private-practice career, using a recent resident graduating class. A list of 2016 radiation oncology resident graduates (163 residents from 76 Accreditation Council for Graduate Medical Education-certified programs) and their postresidency career choice (academic vs private practice) was compiled. The Scopus bibliometric citation database was then searched to collect h-index data for each resident. Demographics included in analyses were gender and PhD degree status. Mean h-index score for all resident graduates was 4.15. Residents with a PhD had significantly higher h-index scores (6.75 vs 3.42; P < .01), whereas there was no statistically significant difference in h-index scores between male and female residents (4.38 vs 3.36; P = .06). With regard to career choice, residents choosing academic careers had higher h-index scores than those choosing private practice (5.41 vs 2.96; P < .01). There was no significant difference in mean h-index scores between male and female residents regardless of private-practice (3.15 vs 2.19; P = .25) or academic (5.80 vs 4.30; P = .13) career choice. The average radiation oncology resident graduate published a minimum of 4 manuscripts cited at least 4 times. Graduates with a PhD are significantly more likely to have higher h-index scores, as are residents who choose academic over private-practice careers. There is no significant difference in h-index score between male and female residents, regardless of career choice. These results offer up-to-date benchmarks for evaluating radiation oncology resident productivity and have potential utility in predicting postresidency career choices.
