- Blood cultures x 2 sets (10mls in each bottle)
- Bone and tissue samples sent to microbiology for microscopy and culture; these should be obtained by percutaneous biopsy or during surgery. Superficial swabs are discouraged.
Acute osteomyelitis
Do not start antibiotic therapy until above obtained and discuss all cases with microbiology and orthopaedics.
See separate guidance for Diabetic foot infections.
Recommended total duration: 6 weeks (Total duration = IV + oral)
First line | Flucloxacillin 2g every 6 hours IV |
Penicillin allergy OR previous MRSA colonisation or infection | Vancomycin IV (use NHS Lothian Calculator on AMT intranet page); aim trough levels 15-20mg/L |
- Surgical debridement might be required if progression to chronic osteomyelitis is to be avoided.
- Within 7 days after surgery (or, if the infection is being managed without surgery, within 7 days after the start of IV antibiotic treatment) IV to oral switch should be considered. Choice of agent depends on microbiology results.
- When clinically stable, consider OPAT referral for outpatient IV treatment or monitoring of complex oral treatment regimes.
Likely organisms: Staphylococcus aureus
