From Center for Disease Dynamics, Economics & Policy: Between 2011 and 2015, the prevalence of health care-associated infections (HAIs) decreased from 4.0 percent (452 of 11,282) of surveyed patients to 3.2 percent (394 of 12,299), according to point prevalence surveys carried out in 10 US states. This was driven by decreased prevalence of surgical-site and urinary tract infections. After adjusting for patient age, hospital size, use of medical devices, and days from admission to survey, the risk of contracting an HAI was 16 percent lower in 2015 than in 2011.
