Invasive candidiasis is associated with worse outcomes and increased mortality in critically ill patients. The Candida score (CS) provides a clinical tool for identifying patients at risk for invasive candidiasis. Outcomes of severely injured trauma patients with positive candida cultures stratified by their CS have not been well described. In this retrospective observational study, all severely injured trauma patients (Injury Severity Score ≥16) admitted to the Los Angeles County and University of Southern California Medical Center from April 2008 to April 2014 with positive Candida cultures were included. Outcomes of patients with a low risk for invasive candidiasis (CS < 3) were compared with those with a high risk (CS ≥ 3). A CS ≥ 3 was significantly associated with higher mortality (35.9% vs 5.0%, P = 0.001), longer length of stay (LOS) (median 49.0 vs 28.0, P = 0.002), longer intensive care unit LOS (35.0 vs 20.0, P < 0.001), requirement for renal replacement therapy (38.5% vs 4.9%, P < 0.001), and increased ventilator days (22.0 vs 12.0, P < 0.001). Multivariable regression analysis revealed a CS ≥ 3 as a significant predictor for increased mortality [OR 6.983], longer LOS [regression coefficient (RC) 1.572] and intensive care unit LOS (RC 1.698), more frequent need for renal replacement therapy (OR 13.268), and increased ventilator days (RC 1.836). In conclusion, a CS ≥ 3 is significantly associated with increased mortality and worse outcomes in severely injured trauma patients with positive Candida cultures. The CS thus may serve as a clinical tool to predict outcomes in this patient population.
