Factors Associated with the Transfer Decision in Resuscitated Patients with Out-of-Hospital Cardiac Arrest Presenting to a Hospital with Limited Targeted Temperature Management Capability in Korea

초록

This study aimed to identify factors associated with the decision to transfer resuscitated patients with out-of-hospital cardiac arrest (OHCA) who were initially examined at hospitals with limited targeted temperature management capability (HLTC) in Korea. We included adult patients with OHCA who were initially transported to HLTC from 2012 to 2015. We limited the study population with OHCA who were admitted or transferred. Potential factors associated with the transfer decision were categorized as patient- or hospital-level characteristics. The primary outcome was emergency department disposition: transfer out versus admission to HLTC. A stepwise multivariable logistic regression analysis was conducted to identify factors associated with the outcome. Of the 64,696 patients with OHCA, 37,705 (58.3%) were initially transported to HLTC. Approximately 44.7% of patients were transferred out. In terms of patient-level factors, age, socioeconomic status, and initial electrocardiogram rhythm were associated with the transfer decision. Hospital factors, such as percutaneous coronary intervention capability of HLTC (adjusted odds ratio=0.16; 95% confidence interval=0.14-0.19) and location of the metropolitan or urban hospital, were negatively associated with the transfer decision. Several hospital and patient factors were associated with the decision to transfer out patients with OHCA who were initially examined at HLTC.
