Incidence, Microbiology, and Outcomes in Patients Hospitalized With Infective Endocarditis

Abstract

Despite changes in antibiotic prophylaxis guidelines, the crude incidence of infective endocarditis has remained stable. However, the incidence rate has doubled in the elderly. Positive blood cultures were observed in less than half of patients, with <i>Staphylococcus aureus</i> and enterococcus bacteremia associated with worse outcomes.
