When Should EMS Call a Child a Small Adult: Inconsistency in Protocol Definitions

Abstract

Age may be a factor in Emergency Medical Services (EMS) treatment of patients, and understanding of age-related patient differences is important to those providing care in the prehospital environment. The US Health Resources and Services Administration’s Maternal Child Health Bureau (HRSA MCHB) through their Emergency Medical Services for Children (EMSC) program has coordinated a focus on pediatric EMS care. However, there is a wide variety of age and other categorizations used to define the pediatric EMS population. This paper reviews the current state of pediatric EMS categorization from several sources, including national-level agencies and organizations, EMS Protocols, and other sources, and provides an overview of the anatomic, physiologic, and behavioral parameters that are generally expected within the range of pediatric ages. We found that, of 32 states publishing statewide EMS protocols online, there was great variability in the definition of a pediatric patient. The age at which states identified the transition from pediatric to adult patient ranged from 12-18 years old, and several states used non-aged-based definitions.
