Abstract

Summary: Background: Use of vascular and cardiac devices has expanded and is associated with a relative, though disproportionate, increase in device-associated infections. Aim: To describe the association between cardiac/vascular device infections and outcomes in those with, and without systemic infections. Methods: We used the 2016 National Inpatient Sample and the International Classification of Diseases – 10 th revision codes to identify hospitalized individuals with vascular and cardiac device infections. Linear and logistic regression models were utilized to compare outcomes of death, length of stay (LOS) and hospitalization costs between individuals with and without systemic infection. Findings: There were a total of 65, 110 hospitalizations associated with device infections with a mean age of 61.3 ± 15.9 years (standard deviation); 28, 650 (44%) had systemic infections. Elixhauser comorbidity scores of three or greater were observed in 91.2% of individuals with systemic infections along with a higher prevalence of diabetes, renal disease and heart failure. The primary outcome of mortality was observed in 3965 individuals with an odds ratio of 3.97 (95% confidence interval (CI), 2.92–3.95) in those with systemic infections compared with those without. Mean LOS was 3.44 days longer (95% CI, 2.92–3.95) and mean cost was US$11, 776 greater (95% CI, US$9826–12, 727) in the systemic infection cohort. Conclusion: Systemic cardiac and vascular device infections were associated with increased mortality, LOS and costs. Considering the increasing use of these life-saving devices, further work is needed to identify those at risk for infectious complications, particularly systemic infection, in order to enhance preventative strategies and improve health outcomes.
