Welcome to the Los Angeles (LA) County Department of Public Health (DPH) Antimicrobial Use (AU) Dashboard. This dashboard provides summaries of aggregated countywide antimicrobial use, expressed as SAARs (Standardized Antimicrobial Administration Ratios) using the 2023 baseline models, and antimicrobial DOTs (days of therapy per 1,000 days present). These county-level AU data are intended to provide comparative insights to help guide facility antimicrobial stewardship efforts. The footnotes below provide guidance for navigating the dashboard. Click to view a complete list of the 2023 baseline SAAR Types, Antimicrobial Categories and Locations. Footnotes Navigating the Antibiotic Use dashboard: Tabs across the top of the dashboard can be used to navigate to various pages of the dashboard. Selections can be made within the filters for SAAR antimicrobial categories, SAAR Types, time period, and facility bed size. The selected information will be displayed in graphs. Most filters are multiselect to provide more options for aggregating and displaying the data. Hover the curser over individual bars and data points on the graphs to view the numeric results, confidence intervals and hospital counts. Full page views of the graphs are available by clicking above the upper right corner of the graph. Abbreviations and terms used in the dashboard: Antibiotic DOTs: Antimicrobial days of therapy per 1000 days present SAAR: Standardized Antimicrobial Administration Ratio SAAR Type: Adult and Pediatric antimicrobial category – location combinations (e.g., adult antifungals in ICU) SAAR Antimicrobial Category: Groupings of antimicrobials considered of interest for antimicrobial stewardship SAAR Location: Hospital locations considered of interest for antimicrobial stewardship Click to view a complete list of the 2023 baseline SAAR Types, Antimicrobial Categories and Locations. Data Source: Data displayed in this dashboard are derived from LA County acute care facilities actively participating in the National Healthcare Safety Network (NHSN) Antimicrobial Use (AU) Module. Beginning in 2026, hospitals participating in the CMS Promoting Interoperability Program are required to submit at least 180 consecutive days of AU data annually to maintain active participation. The number of facilities that contributed data may vary depending on the selected SAAR type and reporting period. Aggregated Standardized Antimicrobial Administration Ratio (SAAR) estimates based on fewer than five facilities should be interpreted with caution, as these estimates may be less stable and more subject to variation. NHSN provides local public health departments with access to AU data within their jurisdiction for surveillance and outreach purposes only. Data is subject to change following NHSN quality assurance reviews and data revisions. This dashboard is maintained by the Antimicrobial Stewardship Program at the Los Angeles County Department of Public Health. For questions or feedback, please contact: Stewardship@ph.lacounty.gov
