Abstract
Graphical abstract Figure. No caption available. HighlightsHospital‐acquired urinary tract‐related bloodstream infections are rare but deadly.Staphylococcal species are a common etiology of this infection in this cohort of veteran patients.It is often days to weeks before a secondary bloodstream infection develops. Background: Hospital‐acquired urinary tract‐related bloodstream infections are rare but often lethal. Recent epidemiology of this condition among the United States veteran population is poorly described. Methods: We conducted a retrospective review of hospital‐acquired urinary tract‐related bloodstream infections of adult inpatients admitted to 4 Veterans Affairs hospitals over 15 years. Electronic medical records were used to obtain clinical, demographic, and microbiologic information. Descriptive statistical analyses were conducted using chi‐square tests of association. Test for trend was performed by genus of organism and for case fatality rate over time. Results: While the most commonly isolated organisms were Staphylococcus spp. (36.5%), the incidence of infections caused by Escherichia and Klebsiella increased over time (P = .02 and P = .03, respectively). The overall in‐hospital case fatality rate was 24.2% in 499 patients. The case fatality rate was 25.8% for patients with Staphylococcus infections and 20.7% for patients with enterococcal infections. Conclusions: Hospital‐acquired urinary tract‐related bloodstream infection is commonly due to…
