Trends in central-line-associated bloodstream infections and catheter-associated urinary tract infections in a large acute-care hospital system in New York City, 2016-2019.

Across an 11-hospital system, continuing efforts to reduce device utilization and infection rates resulted in declining SIRs for CLABSIs and CAUTIs. Hospitals with higher case-mix indices, and particularly level 1 trauma centers, had significantly higher central-line infection rates and SIRs.
