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

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

  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
  1. 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 75th 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.
