- Healthcare-associated Infections in the United States, 2006-2016: A Story of Progress – In this report, CDC uses NHSN, EIP, and HAI prevalence survey data to examine the nation’s progress preventing five of the most common infections: central line-associated bloodstream infections, catheter-associated urinary tract infections, select surgical site infections, hospital-onset C. difficile infections, and hospital-onset methicillin-resistant Staphylococcus aureus (MRSA) bacteremia (bloodstream infections).
- The 2015 National and State Healthcare-associated Infection Data Report – This report looks at individual state and national SIRs, the summary statistic used to track HAI prevention progress over time, using the new national 2015 baseline. To coincide with the new, five-year (2015-2020) goals stated in the HHS HAI Action Plan, the 2015 baseline will be used for all HAI measures beginning with data reported to NHSN in 2015. This report does not compare national or state-specific SIRs in 2015 to SIRs from 2014.
- National 2015 Standardized Infection Ratios (SIRs) Calculated Using Historical Baselines – One element of the updates and improvements to NHSN was resetting the baseline used to measure HAI progress. Before 2015, the baselines, or reference points, varied among the different HAI measures (e.g. several infections had different baselines). Also, because so much progress was made and norms for HAI prevention were more advanced, it no longer made sense to compare recent progress against older baselines. Periodic rebaselining is and will continue to be important to help continue the progress of preventing HAIs. In this report, CDC reviews and provides in-depth details about infection definition changes within NHSN that impacted data during that time period.

Multistate Point-Prevalence Survey of Health Care–Associated Infections – This survey described the burden of HAIs in U.S. hospitals, and reported that, in 2011, there were an estimated 722,000 HAIs in U.S. acute care hospitals. Additionally, about 75,000 patients with HAIs died during their hospitalizations. More than half of all HAIs occurred outside of the intensive care unit.
