Abstract
BACKGROUND: Due to complex invasive medical procedures and compromised immunity, solid-organ transplant (SOT) patients are at high risk for infections. However, whether SOT patients are at higher risk than other hospitalized patients for selected healthcare-associated infections (HAI), such as central line-associated bloodstream infections (CLABSI) or catheter-associated urinary tract infections (CAUTI), or for infections with antimicrobial-resistant (AR) pathogens, is not well described. We analyzed data reported to the Centers for Disease Control and Prevention’s (CDC’s) National Healthcare Safety Network (NHSN) from inpatient SOT units and compared CLABSI and CAUTI rates and AR in hospitals with both SOT and non-SOT units. METHODS: We analyzed 2015–2017 CLABSI and CAUTI data reported to NHSN from hospitals with adult or pediatric inpatient SOT units. We calculated CLABSI and CAUTI incidence rates per 1,000 central-line days (CLD) and urinary catheter days (UCD), respectively, and compared rates, pathogen distributions, and AR among events attributed to three unit types: (1) SOT units; (2) adult, pediatric, and neonatal critical care units; and (3) adult and pediatric medical, surgical, and combined medical-surgical wards. We compared proportions using χ (2) tests and determined statistical significance at P ≤ 0.05. RESULTS: CLABSI and CAUTI rates in SOT units were lower than rates in critical care units, but higher than rates in wards (table). Although the most common CLABSI and CAUTI pathogens were similar in all three unit types, the prevalence of individual pathogens differed (figure). Among CLABSI pathogens, Enterococcus faecium, Escherichia coli, and Klebsiella pneumoniae or oxytoca were significantly more prevalent in SOT compared with critical care units. Vancomycin resistance among CLABSI E. faecium was significantly lower (71.4% vs. 87.5%) and fluoroquinolone resistance among CAUTI E. coli was significantly higher (49.3% vs. 32.5%) in SOT compared with critical care units. CONCLUSION: SOT units have lower CLABSI and CAUTI rates compared with critical care units. Differences in pathogens and AR among device-associated HAIs in SOT units should be considered when implementing infection prevention and treatment policies.
