Abstract
BACKGROUND: An internal quality assurance review at AtlantiCare Regional Medical Center (ARMC) revealed that patients admitted with skin and soft tissue infections (SSTIs) remained in hospital post-resolution of acute symptoms and demonstrated a delayed transition to step-down oral antibiotic therapy. A non-mandatory institutional pathway was developed and implemented in 2016 to expedite hospital discharge in hemodynamically stable SSTI patients by utilizing oritavancin. OBJECTIVE: To describe the outcomes associated with use of single-dose oritavancin therapy to expedite hospital discharge in hemodynamically stable inpatients with SSTIs. METHODS: A retrospective, descriptive cohort was evaluated for outcomes of patients with SSTIs who received either oritavancin to expedite discharge or were discharged on oral step-down antibiotics. Patients were included in this analysis if they were: ≥ 18 years old; hospitalized; received empiric vancomycin; not pregnant or nursing; hemodynamically stable at the time of assessment; and received either oritavancin or oral step-down antibiotics to facilitate discharge. The primary outcomes were index hospital length of stay (LOS), 30-day SSTI-related readmissions, and 30-day SSTI progression. RESULTS: Overall, 199 patients met the study criteria (oritavancin = 99 and oral step-down antibiotics = 100). Groups were well matched at baseline. Patients who received oritavancin had a shorter mean index hospital LOS than those in the oral step-down antibiotic group (3.5 days vs. 5.6 days). Patients receiving oritavancin also had lower SSTI 30-day readmission and SSTI-progression rates. CONCLUSIONS: An institutional pathway that used oritavancin to expedite hospital discharge of hemodynamically stable SSTI patients resulted in shorter hospital LOS, less 30-day SSTI-related hospital readmissions, and decreased SSTI progression relative to those discharged on conventional oral step-down therapy.
