CDC is holding a webinar series designed to inform infection preventionists and public health partners on the new national baseline for healthcare-associated infections (HAIs) reported to the National Healthcare Safety Network (NHSN). The goal is to ensure participants understand the purpose and approach for re-baselining and that they understand factors used in the updated calculations for the standardized infection ratio (SIR). NHSN’s subject matter experts will also provide an overview of how the new SIRs are shared with CMS for various CMS programs. There will also be an opportunity to ask subject matter experts questions during the live chat portion of the webinar. Part 1 will be on Wednesday, October 5, 2016, 2-3:30 PM EDT. Register for the webinar.
