Multivariable Logistic Regression Model for the Prediction of Poor Neurologic Outcome at ICU Discharge, using BIS and sedation requirement data seven hours following ICU admission for cardiac arrest

Variable	Adjusted Odds Ratios (95% CI) for Poor Outcome	P-value
BIS score, 10 point increase	0.41 (0.24 – 0.68)	<0.001
Sedation requirement, 50% increase	0.52 (0.26 – 1.06)	0.07
Age, 10 year increase	0.86 (0.54 – 1.38)	0.54
Time to return of spontaneous circulation, 5 min increase	1.79 (1.16 – 2.77)	0.009
Initial post-arrest PEA or asystolic rhythm, compared to VT or VF	4.33 (0.94 – 20.04)	0.06

CI, confidence interval; PEA, pulseless electrical activity; VT, ventricular tachycardia; VF, ventricular fibrillation; BIS, bispectral index.
