Abstract 346: Cardiac Diagnoses and Initial Presentation to the Emergency Department May Be Associated With Hospital Mortality Among Hospitalized Pediatric Patients Who Experience Medical Emergency Team Events

Abstract

Introduction: There is a paucity of data regarding the association of pediatric patient characteristics with hospital mortality and transfer to higher levels of care following medical emergency team (MET) events. Objective: To explore associations of patient characteristics with hospital mortality and transfer to higher levels of care among pediatric patients who experienced a MET event during an admission. Methods: This retrospective observational study included data from patients aged ≤17 years admitted to an urban, tertiary hospital who experienced a MET event between 2014 and 2017. Data specific to the initial MET event for a patient were included for analysis. Multiple logistic regression models were used to test associations between patient characteristics (age, race, sex, ethnicity, timing of MET event, primary admission diagnosis, receiving care on specialized units) and each outcome separately. Results: Of the 366 patients eligible for inclusion, 11% (41 of 366) experienced hospital mortality, and 59% (216 of 366) were transferred to higher levels of care following MET events. Hospital mortality was lower among those who received emergency department care within 24 hours before the MET event compared to patients who did not (OR=0.17; 95% CI=0.04-0.82). Hospital mortality was higher among those with cardiac-related primary admission diagnoses compared to patients with noncardiac-related diagnoses (OR=3.44; 95% CI=1.04-11.39), and among those of unknown race compared to white patients (OR=3.14; 95% CI=1.17-8.48). No patient characteristics were associated with transfers to higher levels of care. Conclusions: While MET events may cause concern about failures to triage patients to appropriate levels of care upon admission, we observed that patients admitted from the emergency department within 24 hours before their MET event were more likely to survive to discharge. Higher hospital mortality following MET events was observed among patients with cardiac diagnoses and those of unknown race; more research is needed to understand how processes and documentation of care are related to these patients. Further study of how these characteristics and other potential confounding factors are associated with MET events and outcomes is warranted.
