Mild hypoglycemia is strongly associated with increased intensive care unit length of stay

Table 2 Multivariate analysis of factors independently associated with prolonged ICU LOS

	OR (95% CI)	P value
Mechanical ventilation	3.82 (3.20-4.51)	< 0.0001
Minimum BG < 70 mg/dL	2.50 (2.12-2.95)	< 0.0001
Minimum BG 50-69 mg/dL	2.16 (1.81-2.59)	< 0.0001
Minimum BG < 50 mg/dL	1.78 (1.39-2.29)	< 0.0001
Medical diagnosis on admission	1.59 (1.34-1.88)	< 0.0001
Modified APACHE II score	1.04 (1.03-1.06)	< 0.0001
Age	1.00 (0.99-1.01)	0.6002

The 5 parameters in these multivariate models were each significant at p < 0.10 on univariate analysis. Diabetes was not significant on univariate analysis and is therefore not included in the models. Prolonged ICU LOS is defined as greater than the 75^th percentile for each cohort (3.1, 6.6, and 12.8 days for ST, NL and GL respectively). OR per year for age and per point for Modified APACHE II score.
