Background/Aim: Candidemia is a common cause of bloodstream infections in critically ill patients, resulting in high mortality and morbidity. This retrospective case-control study was designed to identify epidemiological characteristics and risk factors for candidemia in an intensive care unit. Methods: A total of 166 patients hospitalized in the intensive care unit between January 2013 and December 2017 were included in this case-control study. Candidemia was defined as at least one positive blood culture for Candida spp. with fever or other clinical findings consistent with infection. Patients who acquired candidemia more than 48 hours after admission represented the case group (n=83). Control group (n=83) consisted of case-matching patients who were hospitalized during the same period and did not develop candidemia. Results: In the candidemia group Candida albicans (57.8%) was the most common species, followed by Candida glabrata (13.3%) and Candida parapsilosis (12%). The rate of C. albicans decreased from 69.2% to 50% during the five-year study period. Out of 83 candidemia infections, 36 (43.4%) were associated with central venous catheters. C. parapsilosis had an increasing rate in parallel with central venous catheter-associated candidemia rates. When comparing cases and controls, in univariate analysis, Sequential Organ Failure Assessment (SOFA) score, blood transfusion, central venous catheter placement, intubation, gastrointestinal surgery and total parenteral nutrition were significantly more common in the candidemia group (P
