Health Care-Associated Infections in U.S. Hospitals, 2023 versus 2015

Listen to this summary

The authors aimed to assess changes in the prevalence of health care-associated infections (HAIs) in U.S. hospitals by comparing data from 2023 to previous surveys conducted in 2015. Their findings indicate a decrease in the prevalence of HAIs, with 2.6% of patients affected in 2023 compared to 3.2% in 2015, although the overall burden remains significant, with an estimated 518,000 HAIs in U.S. hospitals in 2023. Notably, a majority of these infections were not linked to medical devices or procedures.
