ObjectivesTo examine the clinical characteristics, outcomes, and resource use of adolescents and young adults (AYAs) admitted to PICUs in the United States with respiratory failure.DesignRetrospective cohort study.SettingDe-identified data from 48 U.S. children's hospitals contributing to the Pediatric Health Information System (PHIS) database.PatientsAll patients older than 30 days old with respiratory failure, defined as encounters with clinical transaction codes for noninvasive or invasive mechanical ventilation, admitted to PHIS database PICUs from January 2011 to December 2022. Patients were categorized into five cohorts (< 15, 15-18, 19-21, 22-25, and > 25 yr old).InterventionsNone.Measurements And Main ResultsA total of 430,238 patients were identified. AYA (≥ 15 yr old) accounted for 15% (65,740) of all PICU admissions with respiratory failure. Forty-nine percent (32,232/65,740) of AYA older than 25 years had medical technology dependence compared with 39% in those younger than 15 years (p < 0.001). Sixty-one percent of AYA older than 25 years had a cardiovascular comorbidity compared with 35% of those younger than 15 years (p < 0.001). Forty percent of AYA older than 25 years had a neurologic comorbidity, and 27% a gastrointestinal comorbidity, compared with 27% and 31%, respectively, in those younger than 15 years (all p < 0.001). Compared with those younger than 15 years, AYA median hospital crude mortality rate was higher at 7.7% compared with 5.2%, as were median hospital charges per encounter at $163K (interquartile range [IQR], $77K-$350K) vs. $121K (IQR, $53K-$278K; all p < 0.001). Median ventilator days and hospital length of stay in survivors were similar for all age cohorts.ConclusionsAYA represent a substantial proportion of patients admitted to the PICU with respiratory failure. These individuals have unique comorbidities and are at risk for increased mortality and resource utilization compared with younger patients during hospitalization. Medical complexity and sequelae of pediatric illness may delay the transition of AYA to adult care, necessitating collaboration between adult and pediatric critical care physicians to increase research across the age spectrum and develop and implement appropriate evidence-based guidelines.Copyright © 2024 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.
