Charting the Course: 2022 NHSN HAI Rebaseline
Return to NHSN HAI Rebaseline Homepage
Introduction
The NHSN Team is updating the national baseline used to calculate all healthcare-associated infections (HAI) standardized infection ratios (SIRs) and standardized utilization ratios (SURs) in the Patient Safety Component. This process of updating the national baseline, referred to as the “Rebaseline,” involves the NHSN team analyzing national data and creating updated risk adjustment models to be used in the calculations of future SIR and SUR denominators.
The new baseline represents data reported to NHSN for 2022. New SIR and SUR reports, based on the 2022 national baseline, will be created in the NHSN application in a phased approach. Refer to the resources below for additional information, FAQs, and training opportunities.
The NHSN team remains committed to working with facilities to improve HAI prevention. Measuring progress under an updated national standard is important to understanding prevention efforts and standards in the current healthcare environment. The newly baselined data will continue to drive patient safety and the effort to reduce HAI rates.
SSI SIR model inclusion criteria are detailed in the Analysis section of the NHSN SSI Protocol: Surgical Site Infection (cdc.gov) [PDF – 586 KB] The list of NHSN operative procedure categories is in Table 2 of the same document.
