Tennessee Statewide Antibiogram

An image of a gloved hand holding a petri dish against a solid blue background, with text that reads, "What is an antibiogram? An antibiogram is a report that shows how certain germs, like bacteria and fungi, react to medicines called antibiotics and antifungals. If a medicine helps lower the number of germs or gets rid of them completely, it means the medicine works and could be used to help someone get better. Doctors and clinicians can use antibiograms to find out which medicine is most likely to fight infections caused by specific types of germs. It's like a guide that helps them choose the best treatment."

The Tennessee Department of Health (TDH) Healthcare-Associated Infections and Antimicrobial Resistance (HAI/AR) Program is pleased to release statewide and regionwide antibiograms. Antibiograms are essential tools for guiding the selection of empirical antimicrobial therapy. This particular antibiogram was created by the HAI/AR antimicrobial stewardship team, following the Clinical and Laboratory Standards Institute (CLSI) M39, 5th edition guidelines. It is designed to assist healthcare facilities in making data-driven decisions about empirical therapy, especially when facility-level antibiograms are unavailable. Additionally, it enables users to visualize trends in antimicrobial resistance over time.

This antibiogram includes antimicrobial susceptibility data, reported as final interpretations (i.e. susceptible, intermediate, resistant, non-susceptible, or not tested) collected from the National Healthcare Safety Network (NHSN) Antimicrobial Resistance (AR) Option from 2017 to 2023.
