Epidemiology, clinical characteristics, and outcome of candidemia: experience in a tertiary referral center in the UK

SummaryObjectivesTo review the epidemiology of candidemia in a UK tertiary referral center.MethodsClinical and laboratory data from patients with candidemia were collected prospectively from October 1, 2005 to June 30, 2008 (a 33-month period).ResultsA total of 107 episodes were identified. The incidence was 10.9 episodes/100 000 bed-days. The most common predisposing factors were the use of broad-spectrum antibiotics (92%), the presence of an intravascular device (IVD) (82%), admission to an intensive care unit (ICU) (51%), and recent surgery (50%). Non-Candida albicans species accounted for 58% of the episodes, which is higher than the percentage reported from other UK centers. C. albicans was the most common species, accounting for 43% of episodes, followed by C. glabrata (31%) and C. parapsilosis (20%). Overall C. tropicalis, C. krusei, C. norvegensis, and C. lusitaniae caused 7% of episodes. The crude 30-day mortality rate was 37%. Advanced age (p = 0.003) and the presence of septic shock (p = 0.038) were associated with mortality.ConclusionsCandidemia continues to be associated with a high mortality. Preventative measures should be targeted against high-risk hospitalized patients, especially those in ICUs, the elderly, and those undergoing major surgery. Local surveillance of candidemia is important to optimize management.
