Association of Infection With Patient-Level Outcomes

Outcome Unadjusted Odds Ratio (95% CI) Adjusted Odds Ratio (95% CI) Adjusted Estimate Without Infection Adjusted Estimate With Infection p Value
In-hospital mortality 6.1 (5.1–7.3) 2.8 (2.2–3.6) 2.8% 6.0% <0.0001
Unadjusted Ratio (95% CI) Adjusted Ratio (85% CI) Adjusted Estimate Without Infection Adjusted Estimate With Infection p Value
Length of stay 3.6 (3.4–3.9) 2.3 (2.1–2.4) 11.2 days 25.5 days <0.0001
Hospital costs 2.9 (2.7–3.1) 1.8 (1.7–2.0) $63,300 $115,800 <0.0001

For dichotomous variables (mortality), unadjusted and adjusted odds ratios and 95% confidence intervals are presented. For continuous variables, the ratio of length of stay or hospital costs in those with and without infection, and 95% confidence interval, is presented. The p value presented refers to the adjusted data.

CI = confidence interval; LOS = length of stay.
