Risk prediction for candidemia in surgical intensive care unit patients

OBJECTIVE Patients in surgical intensive care units are thought to be at the highest risk for developing candidemia, especially patients undergoing abdominal surgery. The present study aims to investigate risk factors for candidemia in patients with abdominal surgery. METHODS A retrospective study was undertaken that involved patients admitted to the surgical ICU between January 2016 and January 2017. All postoperative adult patients (>18 years old) who underwent abdominal surgery were included in this study. RESULTS During the one-year study period, 49 patients developed candidemia. Thirty-five of candida isolates were non-albicans strains. Of them, 25 (51%) isolates were Candida parapsilosis, eight (16.3%) isolates were C. glabrata, one (2%) isolate was C. tropicalis and one (2%) isolate was C. kefyr. The median age of all patients enrolled in this study was 60.5±15.6 years. In univariate analysis, the duration of the hospital stays, intensive care unit stay, type of surgery, respiratory failure, total parenteral nutrition, transfusion and use of central venous catheter were significantly higher in patients with candidemia. In multivariate analysis, duration of hospital and intensive care unit stay and use of central venous catheter was associated with an increased risk of candidemia. The mortality rate of case patients was 36.7%. CONCLUSION Patients undergoing abdominal surgery are at increased risk of candidemia, especially the patients with prolonged intensive care unit/hospital stay and the patients with a central venous catheters. Antifungal prophylaxis may be considered for patients with increased risk.
