摘要
We studied the clinical and economic impact of a protocol encouraging the use of fidaxomicin as a first-line drug for treatment of Clostridium difficile infection (CDI) in patients hospitalized during a 2-year period. This study evaluated patients who received oral vancomycin or fidaxomicin for the treatment of CDI during a 2-year period. All included patients were eligible for administration of fidaxomicin via a protocol that encouraged its use for selected patients. The primary clinical endpoint was 90-day readmission with a diagnosis of CDI. Hospital charges and insurance reimbursements for readmissions were calculated along with the cost of CDI therapy to estimate the financial impact of the choice of therapy. Recurrences were seen in 10/49 (20.4%) fidaxomicin patients and 19/46 (41.3%) vancomycin patients (P = 0.027). In a multivariate analysis that included determinations of severity of CDI, serum creatinine increases, and concomitant antibiotic use, only fidaxomicin was significantly associated with decreased recurrence (adjusted odds ratio [aOR], 0.33; 95% confidence interval [CI], 0.12 to 0.93). The total lengths of stay of readmitted patients were 183 days for vancomycin and 87 days for fidaxomicin, with costs of $454,800 and $196,200, respectively. Readmissions for CDI were reimbursed on the basis of the severity of CDI, totaling $151,136 for vancomycin and $107,176 for fidaxomicin. Fidaxomicin drug costs totaled $62,112, and vancomycin drug costs were $6,646. We calculated that the hospital lost an average of $3,286 per fidaxomicin-treated patient and $6,333 per vancomycin-treated patient, thus saving $3,047 per patient with fidaxomicin. Fidaxomicin use for CDI treatment prevented readmission and decreased hospital costs compared to use of oral vancomycin.
