IMPORTANCE Geographic proximity to a pediatric subspecialist is a key factor in obtaining specialized care. However, comparative data regarding the number of pediatric subspecialists, distribution of subspecialists, and patient proximity to subspecialists in the United States between 2003 and 2019 have not been explored; the last known national analysis was published in 2006 and used data from 2003.OBJECTIVE To compare the number and distribution of pediatric subspecialists and patient proximity to pediatric subspecialists in the United States between 2003 and 2019 and to assess whether the increase in the number of pediatric subspecialists is associated with improvements in patient proximity to specialized care and the geographic distribution of pediatric subspecialists. DESIGN, SETTING, AND PARTICIPANTSThis national repeated cross-sectional study used data from the American Board of Pediatrics to examine the overall change in the number of subspecialists for 20 pediatric subspecialties between 2003 and 2019. The study included 24 375 pediatric subspecialists who were 70 years or younger, had active certification from the American Board of Pediatrics as of June 2019, and had addresses in the United States. Subspecialists' addresses were linked by zip code to child population data to evaluate the geographic distribution of subspecialists, the population-weighted averages for service areas, and the straight-line distances to subspecialists. Descriptive statistics and maps were used to examine patient proximity to subspecialists and regional subspecialist distribution and dispersion by hospital referral region. Subspecialist-to-child population ratios per 100 000 children, changes over time, and coefficients of variation were calculated to further elucidate subspecialist distribution. Data were collected in June 2019 and analyzed from July 8, 2019, to December 17, 2019. MAIN OUTCOMES AND MEASURESValues from 2019 were compared with data from 2003 for mean straight-line distance in miles from patients to subspecialists, by subspecialty; percentage of children younger than 18 years living at specific distance ranges; subspecialist-to-child population ratios across hospital referral regions; and coefficients of variation for population ratios. RESULTS Among 24 375 pediatric subspecialists 70 years and younger, 23 436 subspecialists were certified in 1 subspecialty, and 939 subspecialists were certified in more than 1 subspecialty. The number of certified pediatric subspecialists in the United States increased by 76.8% between 2003 and 2019, with increases varying across subspecialties. The estimated means for travel distances decreased among all subspecialties; however, depending on the subspecialty, an estimated 1 million to 39 million children (2%-53%) resided 80 miles or more from a subspecialist. An analysis across hospital referral regions indicated increased subspecialist-to-child ratios and an increased number of regions with a subspecialist but continued wide variation across regions for most subspecialties.

Background To inform discussions of pediatric subspecialty workforce adequacy and characterize its pipeline, we examined trends in first-year fellows in the 14 American Board of Pediatrics (ABP)-certified pediatric medical subspecialties, 2001–2018. Methods Data were obtained from the ABP Certification Management System. We determined, within each subspecialty, the annual number of first-year fellows. We assessed for changes in the population using variables available throughout the study period (gender, medical school location, program region, and program size). We fit linear trendlines and calculated χ 2 statistics. Results The number of first-year pediatric medical subspecialty fellows increased from 751 in 2001 to 1445 in 2018. Fields with the growth of 3 or more fellows per year were Cardiology, Critical Care, Emergency Medicine, Gastroenterology, Neonatology, and Hematology Oncology ( P value <0.05 for all). The number of fellows entering Adolescent Medicine, Child Abuse, Infectious Disease, and Nephrology increased at a rate of 0.5 fellows or fewer per year. Female American Medical Graduates represented the largest and growing proportions of several subspecialties. Distribution of programs by region and size were relatively consistent over time, but varied across subspecialties. Conclusions The number of pediatricians entering medical subspecialty fellowship training is uneven and patterns of growth differ between subspecialties. Impact The number of individuals entering fellowship training has increased between 2001 and 2018. Growth in the number of first-year fellows is uneven. Fields with the greatest growth: Critical Care, Emergency Medicine, and Neonatology. Fields with limited growth: Adolescent Medicine, Child Abuse, Infectious Disease, and Nephrology. Concerns about the pediatric medical subspecialty workforce are not explained by the number of individuals entering the fellowship.

BACKGROUND AND OBJECTIVES: This article is the second of a 2-part series examining results regarding self-reported learning and practice change from the American Board of Pediatrics 2017 pilot of an alternative to the proctored, continuing certification examination, termed the Maintenance of Certification Assessment for Pediatrics (MOCA-Peds). Because of its design, MOCA-Peds has several learning advantages compared with the proctored examination.METHODS: Quantitative and qualitative analyses with 5081 eligible pediatricians who registered to participate in the 2017 pilot; 81.4% (n = 4016) completed a quarter 4 survey and/or the end-of-year survey (January 2018) and compose the analytic sample.RESULTS: Nearly all (97.6%) participating pediatricians said they had learned, refreshed, or enhanced their medical knowledge, and of those, 62.0% had made a practice change related to pilot participation. Differences were noted on the basis of subspecialty status, with 68.9% of general pediatricians having made a practice change compared with 41.4% of subspecialists.Within the 1456 open-ended responses about participants' most significant practice change, responses ranged widely, including both medical care content (eg, "care for corneal abrasions altered," "better inform patients about. . .flu vaccine") and nonspecific content (eg, providing better patient education, using evidence-based medicine, increased use of resources in regular practice). CONCLUSIONS: As a proctored examination alternative, MOCA-Peds positively influenced selfreported learning and practice change. In future evaluation of MOCA-Peds and other medical longitudinal assessments, researchers should study ways to further encourage learning and practice change and sustainability. WHAT'S KNOWN ON THIS SUBJECT: Maintenance of Certification Assessment for Pediatrics is a Web-based knowledge assessment developed by the American Board of Pediatrics as an alternative to an examination at a secure test center. Both the model and Web-based platform were developed with extensive input from practicing pediatricians in 2016.WHAT THIS STUDY ADDS: This article is the second of 2 articles in which results are reported from the Maintenance of Certification Assessment for Pediatrics 2017 pilot conducted with over 5000 pediatricians. We review learning and clinical practice change resulting from participation in this new longitudinal assessment format for continuing certification.

BACKGROUND AND OBJECTIVES:There is an urgent need to prepare pediatricians to care for children with behavioral and mental health (B/MH) conditions. In this study, we evaluate the perceived competence of pediatric residents and recent graduates in the assessment and treatment of B/MH conditions, characterize variation in competence across residency programs, and identify program characteristics associated with high competence.METHODS: Cross-sectional survey of applicants for the initial certifying examination in pediatrics. Questions were focused on (1) who should be competent in B/MH skills, (2) institutional support around B/MH training, and (3) perceived competence in 7 B/MH assessment skills and 9 treatment skills. Competence was rated on a 5-point scale, and high levels of assessment and treatment competence were defined as scores of $4. Composite measures for B/MH assessment and treatment were calculated as mean scores for each domain. We examined variation in residents' self-reported competence across programs and used linear regression to identify factors associated with high levels of competence at the program level.RESULTS: Of applicants, 62.3% responded to the survey (n = 2086). Of these, 32.8% (n = 595) reported high competence in assessment skills and 18.9% (n = 337) in treatment skills. There were large variations in reported competence across programs. Respondents from smaller programs (,30 trainees) reported higher competence in assessment and treatment than those from large programs (P , .001).CONCLUSIONS: Current and recent pediatric trainees do not report high levels of perceived competence in the assessment and treatment of children with B/MH conditions. The substantial variation across programs indicates that the pediatric community should create standards for B/MH training.WHAT'S KNOWN ON THIS SUBJECT: Pediatric residents have historically reported low competence in assessing and treating behavioral and mental health conditions. In 2009, the American Academy of Pediatrics published mental health competencies for pediatric primary care, incentivizing improvements in pediatric training.WHAT THIS STUDY ADDS: As of 2018, pediatric trainees still report low competence in the assessment and treatment of children with behavioral and mental health conditions. Trainees at smaller programs report higher competence, although substantial variation exists across all residency program sizes.

The American Board of Pediatrics (ABP) certifies that general and subspecialty pediatricians meet standards of excellence established by their peers. Certification helps demonstrate that a general pediatrician or pediatric subspecialist has successfully completed accredited training and fulfills continuous certification requirements (Maintenance of Certification [MOC]). One current component of the MOC program is a closed-book examination administered at a secure testing center (ie, the MOC Part 3 examination). In this article, we describe the development of an alternative to this examination termed the "Maintenance of Certification Assessment for Pediatrics" (MOCA-Peds) during 2015–2016. MOCA-Peds was conceptualized as an online, summative (ie, pass/fail), continuous assessment of a pediatrician’s knowledge that would also promote learning. The system would consist of a set number of multiple-choice questions delivered each quarter, with immediate feedback on questions, rationales clarifying correct and incorrect answers, references for further learning, and peer benchmarking. Questions would be delivered quarterly and taken at any time within the quarter in a setting with Internet connectivity and on any device. As part of the development process in 2015–2016, the ABP actively recruited pediatricians to serve as members of a yearlong user panel or single-session focus groups. Refinements to MOCA-Peds were made on the basis of their feedback. MOCA-Peds is being actively piloted with pediatricians in 2017–2018. The ABP anticipates an expected launch in January 2019 of MOCA-Peds for General Pediatrics, Pediatric Gastroenterology, Child Abuse, and Pediatric Infectious Diseases with launch dates for the remaining pediatric subspecialties between 2020 and 2022.
