Child Health and the Neonatal-Perinatal Medicine Workforce: 2020-2040.

In 2022, 3.7 million children were born in the United States, of whom ∼600 000 received care from a neonatologist. The dramatic growth of the neonatal-perinatal medicine (NPM) workforce from 375 in 1975 to 5250 in 2022 has paralleled exploding clinical demand. As newborn medicine continues to push the limits of gestational viability and medical complexity, the NPM workforce must advance in numbers, clinical capability, scientific discovery, and leadership. This article, as part of an American Board of Pediatrics Foundation-sponsored supplement that is designed to project the future of the pediatric subspecialty workforce, features a discussion of the NPM workforce's history and current status, factors that have shaped its current profile, and some plausible scenarios of the workforce's needs and configuration in the future. In the article, we use an analytical model that forecasts the growth trajectory of the neonatologist workforce from 2020 through 2040. The model uses recent data on the number of neonatologists and clinical work equivalents per 100 000 children and projects future workforce supply under several theoretical scenarios created by modifying key baseline parameters. The predictions of this model confirm the need for a greater sustainable clinical capacity of the NPM workforce. Several future trends indicate that there may be geographic shortages of neonatologists, similar to expected shortages in other pediatric subspecialties. We do not address what an appropriate target for workforce size should be with the model or this article because the current and projected geographic variability in the NPM workforce and risk-appropriate care suggest that a uniform answer is unlikely.
