OBJECTIVES: To assess trends in incidence of Candida spp. central line-associated bloodstream infections (CLABSIs) in US NICUs, 1999â€“2009.
METHODS: Data from NICUs participating in the National Nosocomial Infections Surveillance (1999â€“2004) and National Healthcare Safety Network (2006â€“2009) were analyzed. Overall and birth weight-specific incidence rates of Candida spp. CLABSIs per 1000 central line-days were calculated. Trends in incidence were assessed by using Poisson regression, and trends in proportion of CLABSIs identified as Candida albicans were assessed by using weighted-linear regression.
RESULTS: Overall, 398 NICUs reported 1407 Candida spp. CLABSIs (706 due to C albicans) among 1400 neonates. Of the 1400 neonates, 963 (69%) were â‰¤1000 g at the time of birth, and 182 (13%) died. From 1999 to 2009, the overall incidence decreased significantly for CLABSIs due to Candida spp. (0.92 vs 0.2), C albicans (0.53 vs 0.09), and non-albicans Candida spp. (0.39 vs 0.1). Birth weight-specific incidence significantly decreased across all birth weight categories for C albicans. For CLABSIs due to non-albicans Candida spp., significant decreases were detected among all birth weight categories, except among neonates 1501 to 2500 g. The proportion of Candida spp. CLABSIs due to C albicans did not significantly change over time, remaining at âˆ¼50%.
CONCLUSIONS: Incidence of Candida spp. CLABSIs decreased substantially among NICU patients, regardless of birth weight. Decreases in incidence across all birth weight categories, and not only among neonates â‰¤1000 g in whom antifungal prophylaxis may be more common, suggest that multiple factors contributed to the declining incidence.
