HAI Progress Reports

These annual reports use data reported to NHSN’s Patient Safety Component and present national and state-level HAI Standardized Infection Ratios (SIRs) and Standardized Utilization Ratios (SURs). The SIR is a metric used to track HAIs, and compares the number of observed infections to the number of predicted infections. The SUR tracks device utilization by comparing the number of device days to the number of predicted device days. More information is available that describes the SIR pdf icon[PDF – 1 MB] and SUR pdf icon[PDF – 1 MB] methodology.

Healthcare-associated Infections in the United States, 2006-2016: A Story of Progress
CDC uses NHSN, EIP, and HAI prevalence survey data to examine the nation’s progress in preventing five of the most common infections: Central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), select surgical site infections (SSIs), hospital-onset Clostridioides difficile infections (CDI), and hospital-onset methicillin-resistant Staphylococcus aureus (MRSA) bacteremia (bloodstream infections).

2015 Data

SIR Report Under the 2015 Baseline
SIRs are calculated using the updated national 2015 baseline. To coincide with the new, five-year (2015-2020) goals stated in the HAI Action Plan, the 2015 baseline will be used for all HAI measures beginning with data reported to NHSN in 2015.
National SIRs on the Historical Baselines
CDC reviews and provides in-depth details about infection definition changes within NHSN that impacted data during that time period.
