In patients with diabetic foot osteomyelitis who underwent surgical debridement, a 3-week course of systemic antibiotic therapy was noninferior to a 6-week course in terms of clinical remission and adverse events.
Background. In patients with diabetic foot osteomyelitis (DFO) who underwent surgical debridement, we investigated whether a short (3 weeks) duration compared with a long (6 weeks) duration of systemic antibiotic treatment is associated with noninferior results for clinical remission and adverse events (AEs). Methods. In this prospective, randomized, noninferiority pilot trial, we randomized (allocation 1:1) patients with DFO after surgical debridement to either a 3-week or a 6-week course of antibiotic therapy. The minimal duration of follow-up after the end of therapy was 2 months. We compared outcomes using Cox regression and noninferiority analyses (25% margin, power 80%). Results. Among 93 enrolled patients (18% females; median age 65 years), 44 were randomized to the 3-week arm and 49 to the 6-week arm. The median number of surgical debridements was 1 (range, 0-2 interventions). In the intention-to-treat (ITT) population, remission occurred in 37 (84%) of the patients in the 3-week arm compared with 36 (73%) in the 6-week arm (P=.21). The number of AEs was similar in the 2 study arms (17/44 vs 16/49; P=.51), as were the remission incidences in the per-protocol (PP) population (33/39 vs 32/43; P=.26). In multivariate analysis, treatment with the shorter antibiotic course was not significantly associated with remission (ITT population: hazard ratio [HR], 1.1 [95% confidence interval {CI}, .6-1.7]; PP population: HR, 0.8 [95% CI: .5-1.4]). Conclusions. In this randomized controlled pilot trial, a postdebridement systemic antibiotic therapy course for DFO of 3 weeks gave similar (and statistically noninferior) incidences of remission and AE to a course of 6 weeks.
