Daptomycin is a cyclic lipopeptide antibiotic that has been commercially available in Europe since 2006. Daptomycin has rapid bactericidal activity against MRSA and is indicated for gram-positive infections including complicated skin and skin structure infections (cSSSI), right-sided infective endocarditis and Staphylococcus aureus bacteremia (BSI). This study aims to quantify the budgetary impact of utilizing Daptomycin for suspected gram-positive cSSSI and BSI in Germany. A budget impact model was developed to compare the total direct costs of utilizing vancomycin, linezolid, daptomycin, and “other antibiotics” as a single category. A decision tree was constructed on the basis of clinical guidelines and validated by clinicians. Clinical data and laboratory utilization and cost data were derived from a comprehensive review of over 40 publications. Antibiotic utilization and net drug costs were derived using syndicated data from Arlington Medical Resources (AMR). On average, the total direct costs (drug acquisition, lab monitoring, and hospital) of treating a cSSSI patient with the following agents were: vancomycin €2598 (4%, 12% and 84%), linezolid €2742 (37%, 5%, and 58%), daptomycin €3,171 (30%, 7%, and 63%), and other antibiotics €1835 (2%, 10%, and 88%). For BSI patients, total direct costs were: vancomycin €2359 (5%, 13% and 82%), linezolid €3951 (37%, 5%, and 58%), daptomycin €2135 (37%, 7%, and 56%), and other antibiotics €3087 (4%, 10%, and 86%). Extrapolating these costs to an average German hospital with 300 BSI and 1000 cSSSI patients and increasing daptomycin use in BSI from 1% to 6% and in cSSSI from 0.3% to 1.4% would save the hospital €30,151 and €2,971 per year, respectively. Using daptomycin for treating cSSSI is budget neutral and using it for bacteremia patients is associated with favorable economic outcomes when compared with other antibiotics.
