Diabetic foot osteomyelitis (DFO) poses great clinical challenges due to prolonged treatment with antimicrobial therapy. Dalbavancin is a new lipoglycopeptide antimicrobial that has shown great potential in treatment of osteomyelitis. With a two-dosing regimen on day 1 and day 8, dalbavancin cortical bone concentration lasts 8 weeks demonstrating great bone exposure. This single centre, retrospective, observational analysis aimed to assess resolution of infection and healing outcomes in patients with DFO and soft tissue infection. Patients who received two doses of intravenous dalbavancin as an outpatient were compared to a similar cohort who received a prolonged inpatient course of alternative antibiotics (intravenous or oral) prior to dalbavancin availability. Adult patients (60-95 years) presenting with DFO susceptible to Staphylococcus Aureus in Sligo University Hospital from 2016 were eligible for enrolment in the control group. The control group consisted of those who received a prolonged course of inpatient antibiotic therapy prior to dalbavancins availability. They were compared to those who received two doses of intravenous dalbavancin as an outpatient. In total 82 patients were identified for inclusion. (58 patients treated with dalbavancin and 24 patients treated with alternative intravenous antibiotics). After exclusion, 44 patients were deemed eligible for analysis in the primary group and 20 patients were deemed eligible in the control group. Healing was achieved between the two groups with no significant difference (P=0.293). Of those who achieved healing, there was a significant difference in healing times between patients receiving two courses of intravenous dalbavancin versus a prolonged course of alternative intravenous antibiotics (P=0.038). Healing occurred within 97 ±113.7 days in the primary group compared to172 ±119.8 days in the control group. Results of this research suggests that dalbavancin use in DFO reduces healing times when compared to alternative intravenous antibiotics resulting in reduction of inpatient length of stay.
