Cognitive Impairment among Cardiac Arrest Survivors in the ICU: A Retrospective Study

Table 3

Independent predictors for cognitive impairment (MMSE < 24).

	All participants (n = 92)		Participants with follow-up MMSE (n = 53)
			Initial MMSE score		Last MMSE score
	Adjusted OR^† (95% CI)		Adjusted OR^† (95% CI)<		Adjusted OR^† (95% CI)
Age, years	1.04 (1.01–1.07)	0.025	1.01 (0.96–1.06)	0.750	1.07 (1.01–1.14)	0.016
Time to ROSC, min	1.01 (0.98–1.05)	0.498	1.03 (0.96–1.10)	0.433	1.08 (1.02–1.15)	0.012
LOS, day	1.02 (0.98–1.06)	0.298	1.07 (0.97–1.19)	0.181	1.07 (1.00–1.14)	0.044

^†ORs are adjusted for age, time to return of spontaneous circulation, and time to cognitive assessment. MMSE, Mini-Mental State Examination; OR, odds ratio; CI, confidence interval; ROSC, return of spontaneous circulation.
