BACKGROUND: Whether temporal differences alter the clinical outcomes of patients
with out-of-hospital cardiac arrest (OHCA) remains inconclusive. Furthermore, the
relationship between time of day and resuscitation efforts is unknown. METHODS:
We studied adult OHCA patients in the Survey of Survivors after Out-of-Hospital
Cardiac Arrest in the Kanto Region (SOS-KANTO) 2012 study from January 2012 to
March 2013 in Japan. The primary variable was 1-month survival. The secondary
outcome variables were prehospital and in-hospital resuscitation efforts by
bystanders, emergency medical services personnel, and in-hospital healthcare
providers. Daytime was defined as 0701 to 1500 h, evening was defined as 1501 to
2300 h, and night was defined as 2301 to 0700 h. RESULTS: During the study
period, 13,780 patients were included in the analysis. The patients with night
OHCA had significantly lower 1-month survival compared to the patients with
daytime OHCA (night vs. daytime, adjusted odds ratio (OR) 1.66; 95 % confidence
interval (CI), 1.34-2.07; P < 0.0001). The nighttime OHCA patients had
significantly shorter call-response intervals, bystander CPR, in-hospital
intubation, and in-hospital blood gas analyses compared to the daytime and
evening OHCA patients (call-response interval: OR 0.95 and 95 % CI 0.93-0.96;
bystander CPR: OR 0.85 and 95 % CI 0.78-0.93; in-hospital intubation: OR 0.85 and
95 % CI 0.74-0.97; and in-hospital blood gas analysis: OR 0.86 and 95 % CI
0.75-0.98). CONCLUSIONS: There was a significant temporal difference in 1-month
survival after OHCA. The nighttime OHCA patients had significantly decreased
resuscitation efforts by bystanders and in-hospital healthcare providers compared
to those with evening and daytime OHCA.
