OBJECTIVES: Treatment of acute bacterial skin and skin structure infections (ABSSSIs) in the outpatient setting has potential advantages. We performed a subanalysis of outcomes for patients treated as outpatients versus inpatients with dalbavancin, a long-acting lipoglycopeptide, in a phase 3 clinical trial of ABSSSI.
METHODS: The study was a double-blind trial of patients with ABSSSI randomised to receive dalbavancin 1500 mg intravenously as a single dose or two doses (1000 mg followed by 500 mg a week later). The primary endpoint was ≥20% reduction in erythema at 48-72 h after the start of therapy. Patient satisfaction and preference for antibiotic treatment and care setting were measured using the 10-item Skin and Soft Tissue Infection (SSTI) questionnaire at Day 14.
RESULTS: A total of 698 patients were randomised (386 treated as outpatients and 312 as inpatients). Outpatients were more likely to be younger and to have major abscess or traumatic wound infection; inpatients were more likely to have cellulitis as the type of ABSSSI, to meet SIRS criteria and to have elevated plasma lactate at baseline. Efficacy and safety outcomes at 48-72 h, Days 14 and 28 were similar between patients treated in the outpatient and inpatient setting with either the single-dose or two-dose regimen. Outpatients reported significantly greater convenience and satisfaction with antibiotic treatment and care setting compared with inpatients (P < 0.001).
CONCLUSION: Single-dose dalbavancin is an effective treatment option for outpatients with ABSSSI and is associated with a high degree of patient treatment satisfaction and convenience.
