Abstract
Context: Risk factors for adverse cardiovascular events (ACVE) from drug exposures have been well-characterized in adults but not studied in children. The objective of the present study is to describe the incidence, characteristics, and risk factors for in-hospital ACVEs among pediatric emergency department (ED) patients with acute drug exposures.
Methods: This is a prospective cohort design evaluating patients in the Toxicology Investigators Consortium (ToxIC) Registry. Pediatric patients (age <18 years) who were evaluated at the bedside by a medical toxicologist for a suspected acute drug exposure were included. The primary outcome was in-hospital ACVE (myocardial injury, shock, ventricular dysrhythmia, or cardiac arrest). The secondary outcome was in-hospital death. Multiple logistic regression analyses were performed to examine novel clinical risk factors and extrapolate adult risk factors (bicarbonate <20 mEq/L; QTc ≥500 ms), for the primary/secondary outcomes.
Results: Among the 13,097 patients (58.5% female), there were 278 in-hospital ACVEs (2.1%) and 39 in-hospital deaths (0.3%). Age and drug class of exposure (specifically opioids and cardiovascular drugs) were independently associated with ACVE. Compared with adolescents, children under 2 years old (OR: 0.41, 95% CI: 0.21–0.80), ages 2–6 (OR: 0.37, 95% CI: 0.21–0.80), and ages 7–12 (OR: 0.51, 95% CI: 0.27–0.95) were significantly less likely to experience an ACVE. Serum bicarbonate concentration <20 mEq/L (OR: 2.31, 95% CI: 1.48–3.60) and QTc ≥ 500 ms (OR: 2.83, 95% CI: 1.67–4.79) were independently associated with ACVE.
Conclusion: Previously derived clinical predictors of ACVE from an adult drug overdose population were successfully extrapolated to this pediatric population. Novel associations with ACVE and death included adolescent age and opioid drug exposures. In the midst of the opioid crisis, these findings urgently warrant further investigation to combat adolescent opioid overdose morbidity and mortality.
