Abstract
OBJECTIVES: The reduction in recurrent Clostridium difficile-associated diarrhea (CDAD) with fidaxomicin therapy may reduce hospital readmissions and lead to lower overall CDAD costs. However, studies assessing the cost-effectiveness of fidaxomicin as first-line therapy from the United States (US) hospital perspective are lacking. This study evaluated the costs associated with utilizing fidaxomicin or vancomycin as a first-line therapy for CDAD in specific patient populations from a US hospital perspective.
METHODS: A decision-analytic model was developed to estimate total costs (hospitalization and drug costs) associated with using fidaxomicin or vancomycin as first-line therapy for a first episode and up to 2 recurrences of CDAD in 5 patient populations: general population, elderly, patients receiving concomitant antibiotics, and patients with renal impairment or cancer.
RESULTS: The total cost of CDAD treatment using fidaxomicin first-line in the general population was $14,442 per patient versus $14,179 per patient with vancomycin first-line. In subgroup analyses, fidaxomicin use resulted in total hospital cost savings of $616 per patient in patients with cancer and $312 in patients with concomitant antibiotic use; vancomycin use was associated with total hospital cost savings of $243 per patient in the elderly and $371 in patients with renal impairment.
CONCLUSIONS: Fidaxomicin as first-line CDAD therapy is associated with similar total costs as compounded vancomycin oral solution in the general population. In elderly and renally-impaired patients, slight increases in hospital cost were observed with fidaxomicin therapy, while in patients with cancer or concomitant antibiotic use hospital cost savings were observed.
