    Abstract:
    The aim of this study was to evaluate the incidence of candidaemia, consumption of fluconazole and susceptibility of blood Candida isolates at a tertiary hospital. From January 1999 to September 2006, all candidaemic episodes were identified and available strains were evaluated for the susceptibilities of antifungal agents. Annual defined daily doses of antifungal agents were collected. There had been 909 Candida isolates detected from the bloodstream of 843 patients during the study period. Among them, 740 isolates were available for the susceptibilities of antifungal agents. The incidence density of candidaemia was 28 episodes per 10,000 patient-days. Species distribution of 909 isolates did not vary annually, but varied greatly in the units of the hospital. Candida parapsilosis was the more prominent (30.1%) isolate in the paediatric units, where C. tropicalis and C. glabrata were less common (12.3% and 1.4% respectively). Resistance rates for itraconazole, fluconazole and voriconazole were 6.9%, 3.8% and 3.8% respectively. There were 25 (3.4%) isolates resistant to amphotericin-B. Although fluconazole usage increased over time (r(2) = 0.45; P = 0.07), fluconazole resistance did not increase accordingly (P = 0.33). In our institution in which the incidence of candidaemia was high, fluconazole resistance among blood Candida isolates remained rare.
