Impact of Center Volume on In-Hospital Mortality in Adult Patients with Out-of-Hospital Cardiac Arrest Resuscitated Using Extracorporeal Cardiopulmonary Resuscitation: A Secondary Analysis of the SAVE-J II Study
This secondary analysis of the SAVE-J II study evaluates the correlation between center volume and in-hospital mortality for patients with out-of-hospital cardiac arrest (OHCA) treated with extracorporeal cardiopulmonary resuscitation (ECPR). Analyzing data from 36 Japanese centers, the study categorizes centers into three groups based on ECPR volume. Findings reveal that high-volume centers (≥21 sessions/year) show a significantly higher survival rate at discharge (33.4%) compared to medium (24.1%) and low-volume (26.8%) centers. Adjusted analysis suggests that patients at high-volume centers are more likely to survive, indicating a positive correlation between center volume and ECPR success.
