Abstract

Abstract: Background: Central line–associated bloodstream infection (CLABSI) is a potentially life‐threatening complication in home parenteral nutrition (HPN) patients. We investigated potential predictors of CLABSI in a cohort of adult HPN patients Methods: Patients managed by the HPN service at the Hospital of University of Pennsylvania on January 1, 2018, were included and followed through June 30, 2019, using existing medical records to collect demographic and clinical data. CLABSIs were adjudicated prospectively by infectious disease experts. Variables with P ≤ .2, when comparing patients with CLABSIs and those without, were included in logistic regression models. Results: Among 114 patients, mean age was 54 ± 16 years, 78/114 were female, and BMI was 25 ± 5.6. Median experience with HPN was 516 days (range, 15–10, 281), and 30 had prior CLABSI. Catheter types were peripherally inserted central catheters (83/114), tunneled (27), and implanted (4). The incidence of CLABSI was 0.89 per 1000 catheter days. One multivariate model identified ostomy/wound (odds ratio [OR], 22.0; 95% CI, 4.8–101.7), tunneled/implanted catheter (OR, 4.4; 95% CI, 1.4–13.9), and BMI < 18.5 (OR, 5.9; 95% CI, 1.4–24.2) as predictors of CLABSI. A second model identified patients with 2 potential predictors (OR, 22.9; 95% CI, 5.6–93.5) and tunneled/implanted catheter (OR, 6.7; 95% CI, 2.1–21.8) at high risk of CLABSI. Whether CLABSIrates might be reduced by more intense training in wound or catheter care (especially for those with multiple predictors), different types of catheters, or rapid treatment of malnutrition will require further study.
