What to know about 2.0: Revisions to the pediatric emergency medicine milestones.

Introduction: The Accreditation Council for Graduate Medical Education (ACGME) adopted educational milestones for trainee assessment in 2013, as a key component of the Next Accreditation System. Two years later, the ACGME, American Board of Pediatrics (ABP), and American Board of Emergency Medicine (ABEM) collaborated to create specialty-specific subcompetencies in pediatric emergency medicine (PEM). Since that time, emerging data have demonstrated the need to revise specialty milestones. Consequently, the ACGME summoned a working group to revise the original PEM milestones. Methods: The PEM Milestones 2.0 Working Group convened in April 2021, comprising diverse representation from ACGME staff, PEM and EM attendings, PEM fellowship program directors, PEM fellows, and community members, overseen by the ACGME's vice president for milestones development. The group met virtually six times over 3 months, with concurrent independent and subgroup work, to draft the PEM Milestones 2.0 and supplemental guide. Results: The working group's revisions generated concise descriptions of behavioral anchors to define skill acquisition more accurately; attention to the transition from residency to fellowship training; incorporation of harmonized milestones for non-patient care and non-medical knowledge domains; and increased emphasis on diversity, equity, and inclusion. A supplemental guide was also designed to aid programs in designing programmatic assessment related to specialty-specific milestones. Conclusions: The PEM Milestones 2.0 provide an updated, specialty-specific framework to guide the development and assessment of PEM fellows and training programs. Future work may focus on faculty and learner development, advancing validity evidence, strengthening content expertise, and integrating milestones with specialty-specific entrustable professional activities.
