Match the Bug to the Drug
• If fever is the patient’s only sign of infection, the patient should not automatically be placed on an antibiotic.• For treatment of a presumed infection, appropriate diagnostic tests, such as cultures, should always be done before starting treatment with antibiotics.
• A single drug and the most narrow-spectrum drug or drugs should be used whenever possible, especially if the infecting organism or organisms are known at the outset.
• Reassess the need for continued antimicrobial therapy daily and modify therapy based on culture results.
• Don’t extend surgical antimicrobial prophylaxis beyond 24 hours postoperatively. Patients undergoing most surgeries can receive a single dose of preoperative antibiotic.
