Dalbavancin Reduces Hospital Stay and Improves Productivity for Patients with Acute Bacterial Skin and Skin Structure Infections: The ENHANCE Trial

INTRODUCTION: Admissions for acute bacterial skin and skin structure infections (ABSSSI) are often prolonged because of intravenous (IV) antibiotics. Use of a long-acting IV antibiotic may reduce length of stay (LOS) on a hospitalist service. The ENHANCE ABSSSI trial sought to determine the impact on LOS and work productivity in patients treated with a long-acting IV antibiotic, dalbavancin, vs. usual care at an urban tertiary-care center. METHODS: A single-center, pre- vs. post-period pragmatic trial at Weill-Cornell Medical Center assessed usual care for consecutively enrolled admitted ABSSSI patients during an observational period (pre-period). Identification and treatment of eligible admitted ABSSSI patients with dalbavancin were implemented in the post-period. Those with life-threatening infections, requiring multiple antibiotics/intensive care, or with unstable comorbidities were excluded. Outcomes were assessed over a 44-day follow-up period. RESULTS: Of 48 and 43 patients enrolled, respectively, in the pre- and post-periods, mean infection-related LOS was reduced in the post-period (3.2 days vs. 4.8 days; P = 0.003). Similar results were found in an adjusted LOS analysis. Work productivity and activity impairment outcomes significantly improved in the post-period (P ≤ 0.01). Complete response rates were similar: 50% (pre-period) and 57% (post-period). Among AEs identified, 17% (n = 7) were found to have possible causal relation to dalbavancin in the post-period. Few AEs were serious (n = 3; 7% post-period versus n = 1; 2% pre-period). CONCLUSION: After implementing the ENHANCE ABSSSI pathway, LOS was significantly reduced by almost 2 days, with potential improvements in work productivity and ability to complete daily activities.
