Outcome indicators of recurrence and amputation were
used to evaluate risk factors and treatment choices in 454 patients
with osteomyelitis who completed outpatient parenteral antimicrobial
therapy (OPAT). Three hundred and fifteen (69.4%) were
apparently cured at the time outcomes were measured and 139 (30.6%)
had a recurrence. Of the recurrences, 56% occurred within
3 months, 78% within 6 months and 95% within 1
year. Both the initial pathogen and the choice of antibiotic had
an effect on the risk of treatment failure. Osteomyelitis caused
by Pseudomonas aeruginosa was associated with more
than a two-fold increase in recurrence (P = 0.005)
compared with infection caused by Staphylococcus aureus. There
was a positive correlation between P. aeruginosa and
amputation. With S. aureus infections, the risk
of recurrence was more than twice as great with vancomycin therapy
as opposed to treatment with

was as effective as the penicillinase-resistant penicillins and
