Cost evaluation of continuation of therapy with dalbavancin compared to standard-of-care antibiotics alone in hospitalized persons who inject drugs with severe gram-positive infections. | LitMetric

AI Article Synopsis

  • PWID are at high risk for severe gram-positive infections, often needing long hospital stays and IV antibiotics; Dalbavancin (DBV) is proposed as a cost-effective treatment option.
  • A study compared two groups of PWID with severe infections: those treated with standard care (SOC) and those treated with DBV, assessing costs, hospital days, and treatment outcomes from 2017 to 2022.
  • Results showed the DBV group had significantly lower healthcare costs ($31,698 vs $45,093) and similar treatment failure rates, suggesting DBV could be a viable alternative to SOC IV antibiotics for this population.

Article Abstract

Purpose: Persons who inject drugs (PWID) are at risk for severe gram-positive infections and may require prolonged hospitalization and intravenous (IV) antibiotic therapy. Dalbavancin (DBV) is a long-acting lipoglycopeptide that may reduce costs and provide effective treatment in this population.

Methods: This was a retrospective review of PWID with severe gram-positive infections. Patients admitted from January 1, 2017, to November 1, 2019 (standard-of-care [SOC] group) and from November 15, 2019, to March 31, 2022 (DBV group) were included. The primary outcome was the total cost to the healthcare system. Secondary outcomes included hospital days saved and treatment failure.

Results: A total of 87 patients were included (37 in the DBV group and 50 in the SOC group). Patients were a median of 34 years old and were predominantly Caucasian (82%). Staphylococcus aureus (82%) was the most common organism, and bacteremia (71%) was the most common type of infection. Compared to the SOC group, the DBV group would have had a median of 14 additional days of hospitalization if they had stayed to complete their therapy (P = 0.014). The median total cost to the healthcare system was significantly lower in the DBV group than in the SOC group ($31,698.00 vs $45,093.50; P = 0.035). The rate of treatment failure was similar between the groups (32.4% in the DBV group vs 36% in the SOC group; P = 0.729).

Conclusion: DBV is a cost-saving alternative to SOC IV antibiotics for severe gram-positive infections in PWID, with similar treatment outcomes. Larger prospective studies, including other patient populations, may demonstrate additional benefit.
