Factors Associated with Pediatric In-Hospital Recurrent Cardiac Arrest

Abstract

The objective of this article was to identify demographic and clinical factors associated with early recurrent arrest (RA) (<48 hours) and late RA (≥48 hours) among pediatric inpatients following an initial in-hospital cardiac arrest. A retrospective cohort study of inpatients was performed in a free-standing academic quaternary care children's hospital. All inpatients were <18 years old with a cardiac arrest event requiring ≥1 minute of cardiopulmonary resuscitation with the return of spontaneous circulation sustained for ≥20 minutes at Seattle Children's Hospital from February 1, 2012 to September 18, 2019. Of the 237 included patients, 20 (8%) patients had an early RA and 30 (13%) had a late RA. Older age and severe pre-arrest acidosis were associated with a higher risk of early RA, odds ratios (OR) 1.2 (95% confidence interval [CI] 1.1–1.3) per additional year and 4.6 (95% CI 1.2–18.1), respectively. Pre-arrest organ dysfunction was also associated with a higher risk of early RA with an OR of 3.3 (95% CI 1.1–9.4) for respiratory dysfunction, OR 1.4 (95% CI 1.1–1.9) for each additional dysfunctional organ system, and OR 1.1 (95% CI 1–1.2) for every one-point increase in PELOD2 score. The neonatal illness category was associated with a lower risk of late RA, OR 0.3 (95% CI 0.1–0.97), and severe post-arrest acidosis was associated with a higher risk of late RA, OR 4.2 (95% CI 1.1–15). Several demographic and clinical factors offer some ability to identify children who sustain a recurrent cardiac arrest, offering a potential opportunity for intervention to prevent early recurrent arrest.
