Methods: More than 4,000 facilities reported data to NHSN using standard methods to identify CAUTI events (symptomatic UTI or asymptomatic bacteremic UTI). Data from adult and pediatric ICUs and wards (including step-down units) were aggregated to describe the prevalence of CAUTIs due to yeast and reported secondary bloodstream infections by location and pathogen. We evaluated differences in the distribution of species in ICU and ward locations using Pearson’s chi-square.
Results: Yeast alone accounted for 8,305 (33%) of the 24,887 CAUTIs reported from ICUs and 2,423 (20%) of the 12,026 CAUTIs from wards. Among the yeasts reported, 72% were identified as Candida spp, of which the species was identified in 91%; the most common species were C. albicans (73%), C. glabrata (16%), and C. tropicalis (7%). There was no statistical difference in the distribution of species reported by location (p=0.2). Of the CAUTIs attributed to yeast, 4% were reported to have secondary bloodstream infections (fungemia), compared to 6% of all other CAUTIs.
Conclusion: Overall, 29% of CAUTIs reported to NHSN were attributed to yeast only. Changes to the NHSN UTI criteria, including removal of yeast, will likely impact CAUTI rates and standardized infection ratios. To evaluate the impact of prevention efforts across this definition change, longitudinal trends can be estimated by retrospectively excluding CAUTIs that no longer meet the criteria. In addition, the potential impact of CAUTI definition changes on reported central line-associated bloodstream infection rates should be tracked, as fungemia can no longer be attributed to a urinary source.
