Background: Candidemias account for 8% to 15% of hospital-acquired bloodstream infections. They have been associated with previous exposure to antimicrobials and are considered high-morbidity infections with high treatment costs. This study characterizes candidemias in a tertiary care hospital and assesses their incidence rates, clinical and microbiological features, and use of antifungals. Methods: We assessed hospital-acquired candidemias in the period from January 1997 to July 2007 in a high-complexity private hospital. Results: There were 151 cases of candidemia in 147 patients. The incidence rate was 0.74 episodes/1000 admissions. The mean age of the patients was 60 years (standard deviation +/- 24.9), and the mean length of hospital stay before the blood culture identified candidemia was 40.9 days (standard deviation +/- 86.3). The in-hospital mortality rate was 44.2%. C albicans was isolated in 44% (n = 67) of the cases, and no difference in mortality rates was found between species (Candida albicans vs C non-albicans, P = .6). The average use of antifungals in the period was 104.0 defined daily dose/1000 patient-days. Conclusion: We found a high mortality rate associated to candidemia events and an increasingly important role of Candida non-albicans. New approaches to health care-related infection control and to defining prophylactic and preemptive therapies should change this scenario in the future.
