The Veterans Affairs methicillin-resistant Staphylococcus aureus (MRSA) Prevention Initiative was implemented in its 133 long-term care facilities in January 2009. Between July 2009 and December 2012, there were ~12.9 million resident-days in these facilities nationwide. During this period, the mean quarterly MRSA admission prevalence increased from 23.3% to 28.7% (P < .0001, Poisson regression for trend), but the overall rate of MRSA health care-associated infections decreased by 36%, from 0.25 to 0.16/1,000 resident-days (P < .0001, Poisson regression for trend).
