This success was 30 driven by the implementation of CDC-recommended interventions at 153 VA hospitals across the country. 25 The VA took steps to prevent the spread of MRSA and device- and procedure-associated infections. This included An estimated 7% decline each year screening all patients for MRSA on admission, tracking 20 MRSA infections, using Contact Precautions (such as gloves and gowns) for people with MRSA, and increasing 15 the emphasis on hand hygiene. 10 Success was also driven by a change in institutional An estimated 17% decline each year from 2005 to 2016, culture, which made preventing MRSA infections the and no change from 2013 to 2016 responsibility of any VA employee taking care of patients. 5 Estimated Cases of MRSA Per 100,000 People 100,000 Per Cases of MRSA Estimated Employee adherence to infection prevention practices was tracked.
