Budget Impact of Omadacycline for the Treatment of Patients with Community-Acquired Bacterial Pneumonia in the United States from the Hospital Perspective.

Background: Community-acquired bacterial pneumonia (CABP) is an acute, lower respiratory bacterial infection. Despite advances in medical care, CABP remains associated with considerable morbidity, mortality, and healthcare costs; early empiric treatment is recommended by the Infectious Diseases Society of America and by the American Thoracic Society. Omadacycline is an oral and intravenous (IV) once-daily aminomethylcycline antibiotic that is approved in the United States for the treatment of adult patients with CABP.

Objective: To estimate the budget impact of introducing omadacycline as a treatment option among patients with suspected or documented CABP from a US hospital perspective.

Methods: A budget impact model was developed in Microsoft Excel 2010. Population, clinical, and cost inputs were based on the available literature, clinical trial data, and real-world evidence databases. Emergency departments and observation units were assumed to be hospital-owned as part of the analyses. Sensitivity analyses assessed the impact of key parameters on the model results, and scenario analyses were explored to analyze the budget impact of reducing length of hospital stay and avoiding hospitalization.

Results: The introduction of omadacycline as a treatment resulted in a total budget increase of $20,643 over 3 years. This increase was mainly attributed to treatment acquisition costs. In a scenario where the length of hospital stay was reduced by 1 day (under the assumption that an antibiotic with IV and oral formulations can facilitate earlier discharge from inpatient care), the 3-year total budget decreased to $2384; reducing the hospital stay by 2 days resulted in 3-year cost-savings of $15,875. Shifting inpatient care to the outpatient setting with omadacycline resulted in 3-year cumulative cost-savings of $112,843.

Conclusion: This is the first omadacycline budget impact model developed for adult patients with suspected or documented CABP. The model projected a modest budget increase with the introduction of omadacycline, mainly due to treatment acquisition costs.
