Background: Dalbavancin (DAL) may obviate concerns regarding misuse of IV access in persons who use drugs (PWUD) completing treatment for infections in an outpatient setting. However, hesitancy to adopt its use exists due to the cost-prohibitive nature of DAL and perceived issues with insurance reimbursement. Our study looks to determine the financial impact of DAL use in actual, measured cost, and health care utilization, data as well as the effect on treatment completion rates. Methods: This is a retrospective cohort comparing cost information and treatment completion rates of patients who received DAL to a random sample of patients with Staphylococcus aureus bacteremia prior to the institutional availability of DAL. Results: From June 2020 to January 2022, 29 PWUD received DAL. Dalbavancin use resulted in the completion of intended duration in 19 patients (66%) compared with 11 (55%) without DAL. The contribution margin with DAL use was $7180 compared with $6655 without; this was not statistically significant (P = 0.47). Conclusion: Dalbavancin use in PWUD may increase treatment completion, with no statistically significant difference in contribution margins.
