Jack Percelay has a 25+ year career in pediatric hospital medicine, beginning before the term hospitalist was invented when he started as an "in-house pediatrician in 1991 at several Bay Area hospitals after a brief career as a civilian primary care pediatrician at local and international US military bases. He has spent the majority of his career in community hospitals where his practice has run the gamut from the general pediatric ward and emergency room, to the PICU and intensive care nurseries, delivery room, and specialized neurologic and neurosurgical units. His work has taken him from San Francisco to New York City with brief stints in Hawaii. In 2015 he moved to Seattle Children's Hospital where he was an Associate Division Chief of Hospital Medicine, and in 2018 returned to the Bay Area joining the Stanford faculty.

He served as the founding chair of the AAP Section on Hospital Medicine, and has also served as the Chair of the AAP Committee on Hospital Care. He served for seven years as the pediatric board member for the Society of Hospital Medicine and has been recognized as a Master of Hospital Medicine by SHM. Additionally, he was an inaugural board member of the American Board of Pediatrics Pediatric Hospital Medicine Subspecialty Board. Areas of interest include pediatric hospital medicine systems of care, patient and family-centered care, BRUEs, billing and coding, and hospitalist roles in the PICU.

    OBJECTIVES: The American Board of Pediatrics (ABP) and the Pediatric Hospital Medicine (PHM) subboard developed a content outline to serve as a blueprint for the inaugural certification examination through practice analysis. The systematic approach of practice analyses process is described in the study.METHODS: A diverse, representative panel of 12 pediatric hospitalists developed the draft content outline using multiple resources (publications, textbooks, PHM Core Competencies, PHM fellow's curriculum, etc). The panel categorized practice knowledge into 13 domains and 202 subdomains. By using the ABP database self-defined practicing pediatric hospitalists were identified. Participants rated the frequency and criticality of content domains and subdomains along with providing open-ended comments.RESULTS: In total, 1449 (12.1%) generalists in the ABP database self-identified as pediatric hospitalists, and 800 full-time pediatric hospitalists responded. The content domains that were rated as highly critical and frequently required in practice were weighted more heavily (ie, the percentage of examination questions associated with a domain) than the less critical and less frequently rated. Both community and noncommunity pediatric hospitalists rated domains similarly (P = .943). Subdomain and preliminary weights were rated with similar means and SDs in the majority of topics.CONCLUSIONS: There was concordance in the rating of domain and universal tasks among both community and noncommunity hospitalists. The areas of significant differences, although minor, could be explained by difference in practice settings. The practice analysis approach was structured, engaged the PHM community, reflected the breadth and depth of knowledge required for PHM practice, and used an iterative process to refine the final product.
