Brief summary

This is a pilot feasibility and safety randomised controlled trial evaluating the optimal duration of antibiotic therapy (4 versus 6 weeks) for the treatment of pelvic osteomyelitis in people living with spinal cord injury, hypothesising that a shorter 4-week treatment course is feasible, safe, and non-inferior to the current 6-week standard with respect to clinical outcomes, while reducing antibiotic exposure and treatment-related harms.

Interventions

This is a pilot, feasibility and safety, randomised controlled trial to be conducted in patients admitted to the Victorian Spinal Cord Service at Austin Health in Melbourne, Australia. Patients with spinal cord injury (SCI) and clinical, radiological, microbiological, or histopathological evidence of osteomyelitis (OM) for multi-disciplinary management will be identified by investigators and assessed for eligibility Patients in the INTERVENTION group will receive 4 weeks of antibiotic therap

This is a pilot, feasibility and safety, randomised controlled trial to be conducted in patients admitted to the Victorian Spinal Cord Service at Austin Health in Melbourne, Australia. Patients with spinal cord injury (SCI) and clinical, radiological, microbiological, or histopathological evidence of osteomyelitis (OM) for multi-disciplinary management will be identified by investigators and assessed for eligibility Patients in the INTERVENTION group will receive 4 weeks of antibiotic therapy (either intravenous or oral) from date of commencement of effective antibiotic therapy, following surgical source control. Antibiotic therapy will be decided by a treating clinician independent of, and prior to, randomization. The antibiotic therapy will be determined by clinical microbiology and antimicrobial susceptibility data independently of subsequent consent and enrolment in the trial. Adherence to medication will be monitored using medical administration records during hospitalisation, community dispensing records when in outpatients, and patient reported adherence.
