Abstract
BackgroundThe impact of dispatcher‐assisted bystander cardiopulmonary resuscitation (CPR) on neurological outcomes in children is unclear. We investigated whether dispatcher‐assisted bystander CPR shows favorable neurological outcomes (Cerebral Performance Category scale 1 or 2) in children with out‐of‐hospital cardiac arrest (OHCA).Methods and ResultsChildren (n=5009, age<18 years) with OHCA were selected from a nationwide Utstein‐style Japanese database (2008–2010) and divided into 3 groups: no bystander CPR (n=2287); bystander CPR with dispatcher instruction (n=2019); and bystander CPR without dispatcher instruction (n=703) groups. The primary endpoint was favorable neurological outcome at 1 month post‐OHCA. Dispatcher CPR instruction was offered to 53.9% of patients, significantly increasing bystander CPR provision rate (adjusted odds ratio [aOR], 7.51; 95% confidence interval [CI], 6.60 to 8.57). Bystander CPR with and without dispatcher instruction were significantly associated with improved 1‐month favorable neurological outcomes (aOR, 1.81 and 1.68; 95% CI, 1.24 to 2.67 and 1.07 to 2.62, respectively), compared to no bystander CPR. Conventional CPR was associated with increased odds of 1‐month favorable neurological outcomes irrespective of etiology of cardiac arrest (aOR, 2.30; 95% CI, 1.56 to 3.41). However, chest‐compression‐only CPR was not associated with 1‐month meaningful outcomes (aOR, 1.05; 95% CI, 0.67 to 1.64).ConclusionsIn children with OHCA, dispatcher‐assisted bystander CPR increased bystander CPR provision rate and was associated with improved 1‐month favorable neurological outcomes, compared to no bystander CPR. Conventional bystander CPR was associated with greater likelihood of neurologically intact survival, compared to chest‐compression‐only CPR, irrespective of cardiac arrest etiology.
