Microbiology of health-care associated endocarditis

In this large cohort, researchers determined the microbiology of community versus health-care associated native valve endocarditis, as well as the differences between nosocomial and non-nosocomial endocarditis (non-nosocomial were those that acquired the disease outside the hospital, but had significant health-care contact, such as long term care, home health, or dialysis). They found 66% were community acquired, and 34% were health-care associated. They found no significant differences between nosocomial and non-nosocomial (of which 45% was staph aureus, 47% MRSA, 15% enterococci, 13% coag-negative staph, and 18% other). This compared to community acquired (of which 20% was staph aureus, 12% MRSA, 28% viridans, and 27% other). Health-care associated native valve endocarditis is a growing problem, the microbiology of which is similar between nosocomial and non-nosocomial (abstract).
