title: Epidemiology, treatment and outcome of candidemia: a five-year review at three Canadian hospitals.
abstract: To determine treatment regimens and epidemiological patterns in the occurrence of candidemia, a review of cases occurring from 1992 to 1996 in three large Canadian hospitals, University of Alberta Hospital (UAH) and Royal Alexandra Hospital (RAH), Edmonton, and Foothills Medical Center (FMC), Calgary, was carried out. Cases were detected by reviewing microbiology laboratory records. There were 202 cases in all (UAH 104, FMC 70, RAH 28). For the five study years the candidemia rate was 4.5/10 000 discharges (UAH 7.6, FMC 4.9, and RAH 1.7; P < 0.05 for all interhospital comparisons). The rate remained stable between 1992 and 1995 but rose dramatically in 1996 to 7.6/10 000 (P < 0.01 compared to 1995) as a result of increases at UAH and RAH. Of the 208 species identified, Candida albicans accounted for 135 (65%). During hospitalization 93 (46%) patients died. Species did not influence outcome. Antifungal treatment with fluconazole alone was given to 14% of patients, and increased in frequency throughout the study. No antifungal therapy was given to 47 patients (23%). This group had a much higher mortality (68%) than those who received treatment (39% P < 0.01). Twenty of the untreated patients had already died by the time the blood culture had been reported as growing a yeast. Candidemia rates vary significantly between hospitals and increased in some but not all over the five study years. As many patients with candidemia will have died by the time laboratory diagnosis is made, presumptive antifungal therapy in high-risk patients may be necessary if outcome is to be improved.
