[Adequacy of new systemic antifungal agents prescriptions in a teaching hospital]. / Revue de pertinence des prescriptions des nouveaux antifongiques systémiques dans un hôpital universitaire.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate the adequacy and the conformity of prescriptions of new systemic antifungal drugs to guidelines and scientific data. PATIENTS AND METHODS: Each prescription of liposomal amphotericin B (lip Amb), voriconazole, and caspofungin made between May 2003 and May 2004 in a teaching hospital were reviewed by an infectious diseases specialist. He used criteria based on marketing authorization, national recommendations, and scientific data. RESULTS: One hundred and fifteen files were studied during the 12-month period and 203 prescriptions analyzed. Most patients were immunodepressed. The indication of the treatment was appropriate for 127 prescriptions (62.6%). Dose and drug interactions were compliant with prescription rules for 158 prescriptions (77.8%). Among the causes of misuse, 16.3% concerned combinations of antifungals. Prescriptions of liposomal amphotericin B, voriconazole and caspofungin complied with guidelines respectively in 69.7, 60.6 and 36.8% of the cases. Among the 127 appropriate prescriptions, the use of cheaper molecules with an equivalent clinical effectiveness would have allowed saving 13.6% of the total cost of these prescriptions. CONCLUSIONS: This study will lead us to implement policies for new antifungal prescription.
