Pediatric Pulmonary Fellowship Program Size Effect on Recruitment and Workforce Distribution.

Background:Concerns about the pediatric pulmonology workforce suggest a need to improve fellowship recruitment. Program size is related to the financial health and recruitment success of pediatric subspecialty education programs, but there are few data on how program size impacts recruitment and workforce in pediatric pulmonology. Objective:Assess the impact of program size in pediatric pulmonology through examination of the distribution of applicants matching into pediatric pulmonology training programs over time and relationships to workforce distribution. Methods:Data from the National Residency Match Program from 2010 to 2022 were extracted from published documents. Positions offered, positioned filled, and match rates were calculated for each appointment year. Statewide statistics for the number of fellows matched were analyzed relative to the number of pediatric pulmonologists per capita using data from the American Board of Pediatrics. Results:From 2010 to 2018, the size and distribution of programs in pediatric pulmonology were stable, with most fellows (82.4%) matching into programs with one or two positions per cycle. Starting in 2019, programs offering three or more positions steadily increased in number and aggregate positions offered. This change was associated with an increase in total filled positions (38.9 ± 7.3 in 2010-2018 vs. 50.5 ± 8.7 in 2019-2022; P < 0.03) and an increased fraction who matched into larger programs (17.6% in 2010-2018 vs. 36.9% in 2019-2022; P < 0.001). Among states with fellowship programs, the number of fellows matched over the past 5 years correlated with the number of practicing pediatric pulmonologists per capita (r = 0.78; P < 0.001). Conclusion:The period 2019-2022 saw a marked shift of pediatric pulmonary trainees matching into a relatively small number of larger programs. This shift was associated with overall growth in the number of trainees but may have implications on geographical distribution of practicing pediatric pulmonologists.
