Abstract

Timing of out-of-hospital cardiac arrests related to social rehabilitation. To clarify the influence of timing of out-of-hospital cardiac arrests to physical and neurological recovery rates, we conducted a multiple logistic regression analysis through nation wide records of cardiac arrest using Utstein templates. We identified 377,705 cases of witnessed out-of-hospital cardiac arrests. The multiple logistic regression models demonstrated that the odds ratio of timing for nighttime versus daytime was 0.78 (95% CI 0.76– 0.81). We concluded that social rehabilitation following out-of-hospital cardiac arrest during nighttime is poorer than during daytime.
