Delayed or inappropriate therapy in candidemia leads to increased mortality thus early recognition becomes paramount. With biomarkers showing promise blood cultures still remain the gold standard but require 24 to 72 hours for growth. The reliance on epidemiologic risk factors for the initiation of empiric antifungal therapy therefore provides the best method for early appropriate therapy. Shorr and colleagues have devised a risk score to identify patients with early-onset candidemia as defined by positive blood cultures within 2 days of admission thus allowing for the initiation of early appropriate antifungal therapy. In a previous edition of Critical Care Shorr and colleagues developed a simple weight risk score for identifying patients with candidemia upon hospital admission 1 . Using recursive partitioning they determined the best discriminators of Candida bloodstream infections in patients upon hospitalization identified as a positive blood culture 1 day prior to or 2 days after admission by retrospectively reviewing the CareFusion Outcomes Research Database comprising 64 109 bloodstream infection cases admitted to 176 acute care hospitals from 2000 to 2005. .
