Abstract
To analyze the demographics, academic background, and scholarly activity of pediatric interventional radiologists (PIRs) across the United States (US) and Canada A list of all members of the Society for Pediatric Interventional Radiology was obtained, and PIRs at academic and private practice institutions in the US and Canada were included. Publicly available online sources were used to gather demographic and educational information, including online curriculum vitae, HealthGrades.com and Doximity.com websites, and Elsevier’s Scopus database. Demographic and educational data such as age, gender, education, academic rank, prior leadership positions, and metrics of scholarly activity were recorded. Fellowships in diagnostic pediatric radiology, adult interventional radiology, and/or pediatric interventional radiology were recorded. Mann-Whitney U and Kruskal-Wallis tests were used to compare the differences between groups. A total of 125 pediatric interventionalists were included, of which 24 (19.2%) were female. The mean age was 48.59 years (SD 10.58, median 45, range 36-82). There was no statistical difference between median age for male versus female PIRs (44.5 vs 45, P = 0.89). A majority of PIRs were American medical school graduates (AMG) (96, 76.8%), while 29 (23.2%) were international medical graduates (IMGs). Eighty-three percent (104) of PIRs completed diagnostic radiology residency in the US, most commonly at the University of Cincinnati (6.4%) and University of Washington at St. Louis (5.6%). Amongst fellowship training, pediatric interventionalists had completed a pediatric radiology fellowship (61.6%), adult interventional radiology fellowship (40%) and/or a dedicated PIR fellowship (57.6%). The mean (and median) publication, citations and h-index for pediatric interventionalists was 31.63 ± 44.84 (12), 668.2 ± 1316.57 (120) and 9.18 ± 10.07 (5), respectively. There was a statistically higher number of publications, citations and h-index with increasing academic rank at assistant, associate and professor levels (P< 0.001 for all groups). IMG PIRs had a higher, but not statistically significant median publication count (26 vs 11, P = 0.25), citation count (236 vs 93, P = 0.35) and h-index (9.0 vs 4.5, P = 0.24), compared to AMG PIRs. Pediatric interventionalists in North America are predominantly male, with about a quarter having graduated from international medical schools. Pediatric radiology fellowship followed by PIR fellowship was the most frequently pursued training pathway.
