Charting the Course: 2022 NHSN HAI Rebaseline

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.

Refer to the resources above for additional information, FAQs, training opportunities, and a link to the NHSN Team’s Rebaseline Progress Tracker, where you can track the progress on model creation, implementation into NHSN, and other aspects of the project.

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.
