    2020 National and State Healthcare-Associated Infections (HAI) Progress Report

    The year 2020 was a tragic and historic year in our nation’s history, marked by the emergence of the COVID-19 global pandemic. With a total of 20 million cases and 372,000 deaths, and daily admissions reaching over 15,000, COVID-19 had a major impact on U.S. healthcare delivery in 20201. Unfortunately, the 2020 National and State Healthcare-Associated infections (HAI) Progress Report suggests that ground has been lost in the progress made in the prevention of several important HAIs in Acute Care Hospitals (ACHs), including a 35% increase in the standardized infection ratio (SIR) for ventilator-associated events (VAE); 24% increase in central line-associated bloodstream infections (CLABSI), and a 15% increase in hospital-onset methicillin-resistant Staphylococcus aureus (MRSA)2. The report also found significant increase in LTACH-onset MRSA bacteremia (20%).
