Evaluation of the Treatment of Candiduria at an Academic Medical Center

To evaluate the epidemiology, management, and outcomes associated with candiduria in intensive care unit (ICU) and medical ward (MW) patients. This was a retrospective cohort study conducted in a tertiary care academic medical center. Adult patients aged between 18 and 75 years who were admitted for at least 5 days with a urinary culture that grew a Candida species between July 2010 and June 2011 were included. Medical records were retrospectively reviewed. Laboratory data, urinary symptoms, risk factors for urinary and invasive candidiasis, treatment, and patient outcomes were collected and evaluated. Sixty-seven ICU and 65 MW patients met the inclusion criteria. ICU patients were more likely to have risk factors for invasive candidiasis and candiduria. Candida albicans and Candida glabrata were the most frequently identified urinary isolates. Antifungal therapy was commonly initiated despite rapid replacement or removal of urinary drainage devices and a lack of patient reported symptoms. Fluconazole was the most commonly used antifungal agent, followed by micafungin. Hospital length of stay did not vary significantly between the ICU and MW groups (P = 0.0628). All-cause mortality was higher in the ICU patients compared with that of the MW patients (22.4% vs. 3.1%, P = 0.0012). Differences exist between ICU and MW patients that develop candiduria with respect to risk factors, and outcomes. Antifungals, including fluconazole and micafungin, were often used inappropriately (ie, asymptomatic patients) in this patient cohort. Efforts to improve healthcare provider awareness of the contemporary recommendations to manage candiduria are necessary to improve patient care and antifungal use.
