MRSA Monitoring

Consult

Infectious diseases consultation is strongly recommended for all patients with Staphylococcus aureus bacteremia.

Note

Coordinate with Pharmacy to target a vancomycin trough level of 15-20 mg/L and monitor renal function.

If Vancomycin MIC greater than or equal to 2mg/L, consult Infectious Diseases for alternative treatment options.

Repeat blood cultures are required to determine clearance of bacteremia. Order repeat blood cultures on day 2, then assess the need for repeat blood cultures every 2 days until clearance.

Please DO NOT write routine orders for daily blood cultures

Persistent bacteremia from blood cultures obtained 4 days after initiation of antibiotics suggests inadequate source control or warrants reassessment of current antibiotic therapy.
