2022 HAI Rebaseline
- NHSN’s Guide to the SIR (2022 Baseline) [PDF – 901 KB] – A resource for understanding the Standardized Infection Ratio (SIR), including calculation methods, inclusion/exclusion criteria, and risk adjustment model details for each applicable HAI and facility type that is currently available in NHSN under the 2022 baseline.
- SIR Model Explorer – 2022 Baseline MRSA Models – An inventory of risk adjustment factors used to calculate SIRs for MRSA Bacteremia LabID events under the 2022 baseline.
- SIR Model Explorer – 2022 Baseline SSI Models – An inventory of risk adjustment factors used to calculate all surgical site infection (SSI) SIRs under the 2022 baseline.
This toolkit offers essential resources for understanding the implications of the 2022 Rebaseline. The resources below aim to facilitate the adoption of the new baseline by healthcare facilities and organizations that use NHSN to track HAI incidence. It includes a detailed implementation guide, a factsheet for baseline analysis, and tailored talking points for infection prevention staff and organizations that use or publish SIRs.
Implementation Guide and Change Log [PDF – 473 KB] – This guide provides comprehensive details on implementing the 2022 baseline within the NHSN application and highlights the new features and functionalities introduced in the 2022 baseline SIR reports, offering a clear comparison to the 2015 baseline SIR reports.
Which Baseline Should I Use for Analyses? [PDF – 291 KB] – This factsheet provides considerations and recommendations for analyzing SIRs or SURs under the 2015 and 2022 national baselines.
Rebaseline Talking Points: Infection Prevention Staff & Hospital Leadership [PDF – 633 KB] – This document provides talking points for hospital infection prevention staff to communicate with hospital leadership. It explains the reasons behind NHSN’s updated SIR and SUR calculations using 2022 data and offers insight on interpreting the updated metrics.
Rebaseline Talking Points: Groups and Organizations that Use or Publish SIRs [PDF – 638 KB] – This document summarizes NHSN’s 2022 HAI Rebaseline and highlights its implications for organizations that use or publish SIR and SUR data from NHSN, ensuring they understand the changes and their impact.
