Abstract

Objectives

A dispatcher-assisted bystander cardiopulmonary resuscitation (DA-BCPR) is expected to influence the outcomes of pediatric out-of-hospital cardiac arrest (OHCA). Our objective was to measure the effect size of a DA-BCPR on survival outcomes according to location of the event.

Methods

All emergency medical service treated OHCA patients younger than 19 years in Korea from January 2012 through December 2013 were analyzed. Patients with OHCA witnessed by emergency medical service providers and those with missing outcome information were excluded. Patients were categorized into the following categories: No-BCPR, BCPR without dispatcher assistance (BCPR-NDA), and BCPR-DA. The primary outcome was survival to hospital discharge. Multivariable logistic regression analysis was performed to calculate the adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for outcomes by exposure group (reference, No-BCPR group) with and without an interaction term between exposure and location of arrest.

Results

A total of 1013 eligible patients were analyzed. Among these patients, 16.6% received BCPR-NDA, 23.2% received BCPR-DA, and 60.2% received no BCPR. After adjusting for potential confounders, compared with N0-BCPR group, AORs for survival were 1.79 (95% CI, 1.03–3.12) in BCPR group, 1.71 (95% CI, 0.85–3.46) in BCPR-NDA group, and 1.39 (95% CI, 0.72–2.69) in BCPR-DA group. The AORs for survival of BCPR-NDA and BCPR-DA in public location were 3.30 (95% CI, 1.12–9.72) and 2.95 (95% CI, 1.00–8.67), whereas BCPR-NDA and BCPR-DA in private locations were 1.62 (95% CI, 0.68–3.88) and 1.15 (95% CI, 0.53–2.51).

Conclusion

The DA-CPR was associated with better outcomes in pediatric OHCA patients whose arrest occurred in public locations, but no improvement in outcomes was identified in patients whose arrest occurred at private locations.
