The Prognosis of Cardiac Origin and Noncardiac Origin in-Hospital Cardiac Arrest Occurring during Night Shifts

Table 3

Cardiac arrest outcomes by day/evening versus night.

Outcome	Day or evening shift	Night shift
	Reference	aOR	95% CI
Cardiac origin
ROSC	[1]	0.3	0.15~0.63
Survival to discharge	[1]	0.1	0.01~0.90
Noncardiac origin
ROSC	[1]	0.5	0.30~0.78
Survival to discharge	[1]	1.3	0.43~3.69

Significant factor.
ROSC: return of spontaneous circulation.
aOR: adjusted odds ratio, for patient’s age, sex, CCI, first documented cardiac rhythm, witnessed cardiac arrest, and bystander CPR.
