Abstract
AIM: We examined whether outcomes of paediatric out-of-hospital cardiac arrest (OHCA) are associated with a hospital characteristic defined by the annual number of invasive mechanical ventilation cases, suggesting hospitals' experience in caring for severely ill paediatric patients. METHOD: We analysed the Japanese Diagnosis Procedure Combination database from 2010 to 2017. We identified children (<18 years) with OHCA and post-resuscitation intensive care (defined as invasive mechanical ventilation and/or catecholamine infusion). Hospitals were divided into four groups by mean annual number of paediatric cases involving invasive mechanical ventilation. The primary outcome was in-hospital mortality, and the secondary outcome was unfavourable outcomes (death or medical care dependency at discharge). Multivariable logistic regression analyses were conducted to examine the relationship between hospitals' experience and outcomes. RESULTS: We included 2540 paediatric OHCA patients from 385 institutions. Overall in-hospital mortality was 62.4%, with rates of 69.6%, 61.3%, 61.8%, and 57.0% in hospitals with low (≤48 cases/year), low-intermediate (48-110), high-intermediate (110-164), and high (>164) experience levels (P < .001), respectively. Compared to hospitals with low experience, adjusted odds ratios (95% confidence interval) for hospitals with low-intermediate, high-intermediate, and high experience were as follows: primary outcome: 0.64 (0.40-1.01), 0.67 (0.42-1.05), and 0.46 (0.31-0.70), respectively; secondary outcome: 0.93 (0.55-1.57), 0.95 (0.63-1.43), and 0.67 (0.46-0.96), respectively. CONCLUSION: Japanese hospitals with higher experience in caring for severely ill paediatric patients showed lower mortality for paediatric OHCA. This fact should be considered by the Emergency Medical Systems when deciding transport strategy.
