Treatment of Osteomyelitis in Adults When Bone Culture Is Positive for Pseudomonas aeruginosa
When osteomyelitis bone culture identifies Pseudomonas aeruginosa as the causative organism, antibiotic selection must be directed specifically at this pathogen. Culture-directed therapy is the standard approach — the organism identified on bone culture determines which agents are appropriate.
Adult patient with osteomyelitis; bone culture positive for Pseudomonas aeruginosa. The choice of antibiotic therapy is specific to the culture result, and the regimen for Pseudomonas aeruginosa differs from that used when other organisms are isolated.
Management involves intravenous combination antibiotic therapy with agents selected for activity against Pseudomonas aeruginosa. More than one combination option exists. The complete regimen — specific agents, the full algorithm, and all clinical decision points — is available in the structured protocol.
