Objective:
To determine whether cardiac arrests occurring at night or during the weekend, carry lower immediate survival.
Method:
An analysis of logistic regression was performed, adjusted for age, sex, time to care of the cardiac arrest and first monitored rhythm, to determine whether there are differences in immediate survival.
Results:
The immediate survival of the cohort studied (n=121) was 32 patients (26%). A difference of 13% in immediate survival between both periods studied was found. The logistic regression analysis taking immediate survival as an effect, showed that suffering an in-hospital cardiac arrest during evenings or weekends was a variable that is not associated with a successful outcome. The OR: .48 (95% CI: .20-1.12; P=.08).
Conclusions:
Patients who suffer a cardiac arrest in our centre during evenings or weekends are more vulnerable.
