Introduction Antimicrobial resistance (AR) is a global concern that presents a growing public health challenge. In order to help promote antimicrobial stewardship and reduce AR, the Los Angeles County Department of Public Health (DPH) has created the first LA County regional antibiogram.
Antibiograms, defined as a summary of antimicrobial susceptibility rates for selected bacterial pathogens, provide comprehensive information about local antimicrobial resistance. They are usually generated by a laboratory using aggregate data from a hospital or healthcare system. This first LA County regional antibiogram aggregates voluntary data from 86 facility-level antibiograms to describe countywide patterns of resistance. DPH is using this community antibiogram to monitor and investigate antibiotic resistance across the county.
Possible uses in health care settings include: 1. informing empiric therapy selection, 2. guiding antimicrobial selection in serious infections, and 3. informing prescribing guidelines. DPH invites providers to complete a
brief survey to give feedback on how the antibiogram is used and how to improve
