Abstract

Introduction: The aim of this study was to compare the epidemiology, risk factors, severity and outcome of two types of ICU-treated candidemias: namely, ICU-acquired candidemia (acquired after 48-hour ICU stay) (ICUAC group), and those needing ICU treatment for candidemia acquired before ICU admission or during the first 48-hour ICU stay (non-ICUAC group). Methods: A retrospective cohort study was conducted between 2000 and 2009 in a mixed tertiary ICU among patients with blood-culture-confirmed candidemia. Results: The study involved 82 patients (53 men). The ICUAC group consisted of 38 patients (46.3%) and the non-ICUA group included 44 patients (53.6). The ICUAC group had undergone previous surgery more often and had ICU stays that were 3.7 times longer than the non-ICUAC group, whose members more often had co-morbidities (95.6% versus 73.7%, P = 0.001). The ICUAC group had significantly more frequent organ failures with cardiovascular, renal, central nervous and coagulation systems than the non-ICUAC group. ICU, hospital and one-year mortality rates did not differ between the groups (23%, 36.8% and 65.8%, respectively, in the ICUAC group and 26%, 44.4% and 64.4%, respectively, in the non-ICUAC group). Among patients with APACHE II scores greater than 25, the ICUAC group had lower one-year mortality (65.0% versus 87.5%). Among patients with APACHE II scores of 25 or less, the ICUAC group had higher mortality (66.7% versus 50.0). Candida albicans was most common cause of candidemia in both groups (76.3% and 68.9%, respectively). Conclusions: More than half of the ICU-treated candidemias were acquired prior to admission to the ICU. Patients with ICU- and non-ICU-acquired candidemias had different risk factors and different needs for ICU resources. Hospital mortality was similar in both groups; however, the groups had different mortality rates when the severity of disease and underlying diseases were taken into account. © 2012 Ylipalosaari et al.; licensee BioMed Central Ltd.
