^a mean ± standard deviation; ^b Cardiovascular disease includes hypertension, dyslipidemia, congestive heart failure, coronary artery disease; ^c Immunosuppressed: malignancy, recent chemotherapy, chronic steroid use (prednisone ≥20 mg/day or equivalent); SAB = S. aureus bacteremia; ^d Sources of infection considered low risk were intravascular (IV) catheters, urinary tract infection, ear-nose-larynx, gynecologic, and several manipulation-related sources; intermediate risk were osteoarticular, soft-tissue, and unknown sources; and high risk were endovascular, lower respiratory tract, intra-abdominal, and central nervous system foci
