Of 1015 patients enrolled, 181 patients (17.8%) had clinically significant bacteremia, including 77 patients (7.6%) with S. aureus bacteremia. Clinical characteristics associated with S. aureus bacteremia were the presence of a hemodialysis graft or shunt (odds ratio [OR] 3.22; 95% confidence interval [CI], 1.85-5.61), chills (OR 2.38; 95% CI, 1.43-3.98), and a history of S. aureus infection (OR 2.68; 95% CI, 1.38-5.20). Peripheral vascular catheters were inversely associated with S. aureus bacteremia (OR 0.42; 95% CI, 0.26-0.69). Clinical characteristics associated with any bloodstream infection were central venous access, chills, history of S. aureus infection, and hemodialysis access.
(BTW: you can translate S. aureus as MRSA).
