ObjectivesDifferences between adult and pediatric in-hospital cardiac arrest (IHCA) are well-described. Although most adults are cared for on adult services, pediatric services often admit adults, particularly those with chronic conditions. The objective of this study is to describe IHCA in adults admitted to pediatric services.DesignRetrospective cohort analysis from the American Heart Association's Get With The Guidelines-Resuscitation registry of a subpopulation of adults with IHCA while admitted to pediatric services. Multivariable logistic regression was used to evaluate adjusted survival outcomes and compare outcomes between age groups (18-21, 22-25, and ≥26 yr old).SettingHospitals contributing to the Get With The Guidelines-Resuscitation registry.PatientsAdult-aged patients (≥ 18 yr) with an index pulseless IHCA while admitted to a pediatric service from 2000 to 2018.InterventionsNone.Measurements And Main ResultsA total of 491 adult IHCAs were recorded on pediatric services at 17 sites, during the 19 years of review, and these events represented 0.1% of all adult IHCAs. In total, 221 cases met inclusion criteria with 139 events excluded due to an initial rhythm of bradycardia with poor perfusion. Median patient age was 22 years (interquartile range, 19-28 yr). Ninety-eight percent of patients had at least one pre-existing condition. Return of spontaneous circulation occurred in 63% of events and 30% of the patients survived to discharge. All age groups had similar rates of survival to discharge (range 26-37%; p = 0.37), and survival did not change over the study period (range 26-37%; p = 0.23 for adjusted survival to discharge).ConclusionsIn this cohort of adults with IHCA while admitted to a pediatric service, we failed to find an association between survival outcomes and age. Additional research is needed to better understand resuscitation in this population.Copyright © 2022 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.
