Significant Predictors of Nosocomial Urinary Tract-Related Bloodstream Infection

Predictor variable	Odds Ratio*	95% Confidence Interval
Neutropenia	10.99	5.78–20.88
Insulin	4.82	2.52–9.21
Renal disease	2.96	1.98–4.41
Urologic procedure	2.49	1.31–4.73
Liver disease	2.34	1.35–4.06
Male sex	2.18	1.52–3.12

^*ORs presented above are from a multivariable conditional logistic regression analysis and were adjusted for all other covariates presented as well as: age, diabetes mellitus, ever vs. never cigarette smoking, hypertension, ICU status 2 days prior to index date, and statin therapy. All pharmacologic therapies modeled were therapies that were administered during the hospital stay 2 days prior to the index date. Index date = bloodstream infection date of the case within each matched case-control set.
