RESUMEN
OBJECTIVES: In 2021 in our university hospital, it was decided in a multidisciplinary consultation meeting on osteoarticular infection in patients with diabetic foot to reduce the duration of post-amputation antibiotic therapy from six to three weeks in patients with diabetic forefoot osteomyelitis and residual bone infection. This study aimed to compare clinical outcomes in this group of patients, before vs after the change in practice introduced in 2021. METHODS: In this before-after study, we included all cases reported between January 2016 and August 2023 in the University Hospital of Reims. RESULTS: We included 113 patients; between 2016 and 2020, 56 (49.5 %) received six weeks of post-amputation antibiotic therapy, and between 2021 and 2023, 57 (50.5 %) received three weeks of therapy. Over six months of follow-up, overall cure rate was 95 %. Treatment failure did not differ between groups. CONCLUSION: Three weeks of post-amputation antibiotic therapy in diabetic patients with forefoot osteomyelitis and residual bone infection is effective.
