Gender-based analysis of pre-residency research productivity among a current United States radiation oncology resident class.


Background: The increasing proportion of women in medicine has not been adequately reflected in the gender distribution of residents, particularly in highly competitive subspecialties such as neurosurgery and radiation oncology. The presence of at least one pre-residency peer-reviewed publication (PRP) was found to be associated with future resident choice of academic over private practice career in a recent radiation oncology resident graduating class, with no significant gender difference in the likelihood of having a PRP (McClelland et al., Practical Radiation Oncology 2017). We sought to pursue a gender-based analysis of PRP productivity in a current junior resident class. Methods: A list of radiation oncology residents from the graduating class of 2022 (PGY-2 academic year of 2018-2019) was obtained through internet investigation. In addition to gender, demographics included dual degree status and presence/absence of a PhD. Research productivity was calculated using PRP number, defined as the number of a resident’s publications listed in PubMed ( through the calendar year of residency application (2016 for the class of 2022), as previously described. Fisher’s exact test was used for statistical analysis. Results: Of 179 residents examined from the 2022 class, 55 (31%) were women, representing a nine percent increase from the resident class of 2016. Four-fifths had at least one PRP, 33% had dual degrees, and 18% had a PhD. These percentages were comparable to their male counterparts, 73% of whom had at least one PRP, 28% who had dual degrees, and 15% who had a PhD. Specific analyses revealed no statistically significant differences by gender in any of these benchmarks (p>0.05). Conclusions: While slower than the overall trend of increased female representation in medicine, the proportion of women in radiation oncology residency has increased by approximately 1.4% per year over a recent six year span. There remain no significant differences in PRP productivity between male and female residents, and there are no significant gender differences in the likelihood of dual degree status or PhD status. Further study will be needed to determine how these findings manifest in career choice following graduation.
