CDC revising NHSN CAUTI SIRs due to error in predictive models

The U.S. Centers for Disease Control and Prevention (CDC) has notified users of the National Healthcare Safety Network (NHSN) that it is revising catheter-associated urinary tract infection (CAUTI) predictive models developed for the 2015 NHSN Standardized Infection Ratio (SIR) rebaseline effort. CDC detected an error in the models used to analyze and report 2015 and 2016 data for acute care hospitals, long-term acute care hospitals, and inpatient rehabilitation facilities. This error is separate from the previously identified issue impacting CLABSI models. 

CDC is working closely with the Centers for Medicare & Medicaid Services (CMS) to determine the impact on CMS payment programs. CMS will communicate information on payment and public reporting to facilities that participate in those programs as soon as possible. All questions about Medicare programs should be directed to CMS at

CDC is working on producing and implementing revised SIRs for affected facilities as quickly as possible in order to provide NHSN users and partners with reliable and actionable data. Questions related to NHSN data should be directed to the NHSN help desk at
