Abstract:
|
U.S. hospitals were voluntarily reporting catheter-associated urinary tract infection (CAUTI) data to CDC's National Healthcare Safety Network (NHSN) surveillance system and required to do so under the CMS reporting mandate beginning in 2012. Historically, CAUTI surveillance definition included yeast which represented 15-30% of CAUTIs. Due to concern over the validity of CAUTI definition as yeast is clinically not considered a valid pathogen based on several factors (e.g. yeast is a rare cause of UTI but catheter colonization is common), NHSN excluded yeast from CAUTI definition in 2015. To examine the validity of new definitional update, we applied interrupted time series method adjusting for facility and unit-level characteristics to examine the trend in CAUTI rate with and without yeast among continuous reporting units (n=1830 in 476 hospitals) from 2009 through 2014. Despite evidence of prevention success, CAUTI rate with yeast increased significantly after 2012 whereas CAUTI rate without yeast showed downward trend during the same time period. Data suggested that new CAUTI definition is clinically and epidemiologically more relevant to monitor success of prevention efforts.
