Background: Data are limited on risk factors for vancomycin-resistant Enterococcris (VRE) bacteremia. Methods: All patients with a confirmed VRE bacteremia in Ontario, Canada, between January 2009 and December 2013 were linked to provincial healthcare administrative data sources and frequency matched to 3 controls based on age, sex, and aggregated diagnosis group. Associations between predictors and VRE bacteremia were estimated by generalized estimating equations and summarized using odds ratios (ORs) and corresponding 95% confidence intervals (CIs). Results: In total, 217 cases and 651 controls were examined. In adjusted analyses, patient-level predictors included bone marrow transplant (OR 106.99 [95% CI 12.19-939.26]): solid organ transplant (OR 17.17 [95% CI 4.95-59.54]): any cancer (OR 8.64 [95% CI 3.88-19.211): intensive care unit (ICU) admission (OR 6.81 [95% CI 3.53-13.13]): heart disease (OR 5.27 [95% CI 2.00-13.90]): and longer length of stay (OR 1.07 per day [95% CI 1.06-1.09]). Hospital-level predictors included hospital size (per increase in 100 beds (OR 1.26 [95% CI 1.07-1.48]) and teaching hospitals (OR 3.87 [95% CI 1.85-8.08]). Conclusions: Patients with a bone marrow transplant, solid organ transplant, cancer, or who are admitted to the ICU are at highest risk of VRE bacteremia, particularly at large hospitals and teaching hospitals.
