Demographics and characteristics of leadership at allergy and immunology fellowships in the U.S. as of 2022

Abstract

Background: The subspecialty of allergy and immunology (AI) has grown tremendously since the first fellowship programs were developed nearly 80 years ago; however, there is little information with regard to the demographic characteristics and trends in training of fellowship directors (FDs). Objective: Our goal was to analyze the demographic characteristics and pathways in training that have led FDs to advance in the field and train the next generation of allergists and immunologists. Methods: We created a list of all current AI fellowship programs and FDs within the United States. Specific biographical, training, and research information was collected via an Internet search and questionnaire responses. The data were recorded and analyzed in a spreadsheet and unpaired t-tests were performed between male versus female groups for H ‐ index comparison to establish if there was a statistically significant difference. Results: There were 84 total AI fellowship programs with 84 FDs. Forty-one FDs (48.8%) were men and 43 FDs (51.2%) were women; mean age was 51.1 years; and the average age at appointment for men was 45.7 years and for women was 41.4 years, with a statistically significant difference (p = 0.02). Self-reported race and ethnicity (77.4% response rate [n = 65]) were as follows: 55.4% white (n = 36), 23.1% Asian (n = 15), 6.2% biracial (n = 4), 7.7% Middle Eastern (n = 5), 4.6% Hispanic (n = 3), and 3.1% Black (n = 2). The average Hirsch-index (h-index) for FDs was 14.2, with an average of 42.1 publications and 1532.2 citations. The difference between the h-index for the men and for the women was statistically significant, being 17.8 and 11.2 respectively, with p = 0.0143. Conclusion: In AI FDs, women were adequately represented, and men and women were hired at similar ages. There was a statistically significant difference in research output (estimated by the h-index) between men and women. This suggests that research output did not limit women in being appointed as FDs.
