Differences in Odds of Community-Associated Bloodstream Infection by Gender and Patient Characteristics at Admission

Patient characteristic	Odds ratio (95 % confidence interval)
Unadjusted model
Gender (female vs. male)	0.75 (0.70–0.82)
Adjusted model*
Gender (female vs. male)	0.85 (0.77–0.93)
Hospital (community vs. tertiary care)	1.23 (1.11–1.35)
Age (1-year increase)	1.006 (1.003–1.008)
Prior stay in skilled nursing facility	2.34 (2.04–2.68)
Prior hospitalization in network	1.43 (1.31–1.55)
Charlson weighted comorbidity index (1-unit increase)	1.07 (1.05–1.09)
Diabetes mellitus†	0.90 (0.82–0.99)
Malignancies†	1.16 (1.01–1.33)
Renal failure†	2.92 (2.66–3.21)
Chronic dermatitis†	2.11 (1.87–2.39)
Solid organ transplant†	1.39 (1.11–1.74)

^*Trauma, burns, and wounds at admission were not significantly associated with incidence of community-associated bloodstream infections and were not included in the final adjusted model
