2018 National and State Healthcare-Associated Infections Progress Report

The 2018 National and State HAI Progress Report provides data on central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), ventilator-associated events (VAEs), surgical site infections (SSIs), methicillin-resistant Staphylococcus aureus (MRSA) bloodstream events, and Clostridioides difficile (C. difficile) events, formerly known as Clostridium difficile. For each of the four healthcare settings, the report consists of national factsheets via the Antibiotic Resistance & Patient Safety Portal, and detailed technical tables; the national factsheets provide a high-level view of HAIs at a national level, while the technical tables include additional statistics about HAIs, reporting mandates, and data validation efforts in each state and select U.S. territories. The report’s national factsheets, as well as the detailed technical tables, include infection-specific standardized infection ratios (SIRs), which measure progress in reducing HAIs compared to the 2015 baseline time period. The SIR is the ratio of the observed number of infections (events) to the number of predicted infections (events) for a summarized time period. In addition to the SIRs, the report includes the standardized utilization ratios (SURs), which measure device use by comparing the number of observed device days to the number of predicted device days. The SIR and SUR metrics are calculated using the 2015 national baseline and risk adjustment methodology. More information about these metrics can be found at:
