Comparative pharmacoeconomic study of vancomycin and teicoplanin in intensive care patients.

Randomized clinical trials and meta-analyses have not demonstrated any statistically significant differences between teicoplanin and vancomycin with regard to efficacy. A cost-minimization analysis was conducted to compare the economical impact of the treatment with vancomycin and teicoplanin in intensive care patients. Information on resource utilization was retrospectively collected from 100 consecutive clinical histories of patients hospitalized in a Spanish Intensive Care Unit, who had been given a glycopeptide antibiotic (50 teicoplanin and 50 vancomycin) for the treatment of a suspected or proven infection. Although personnel, material, and monitoring costs were higher in the vancomycin group, the acquisition costs and the total costs were much lower in this group, so the resulting total costs per day were 5508 ptas (33 euros) for vancomycin-treated patients and 9893 ptas (59.5 euros) for teicoplanin-treated patients. The savings with vancomycin for a 10-day course of treatment would be approximately 40697 ptas (244.5 euros) per patient. Results were consistent for a variety of conditions that were included in the sensitivity analysis.
