The economic impact of rapid Candida species identification by T2Candida among high-risk patients

ABSTRACT Introduction: This study estimates the cost–effectiveness and hospital budget impact of rapid candidemia identification using T2Candida, a novel diagnostic panel with same-day species-specific results. Materials & Methods: A 1-year decision-tree model estimates hospital costs (2013 US$) and effects (candidemia-related deaths) for faster diagnostics versus blood culture (BC), accounting for disease prevalence, distribution of Candida species, test characteristics (sensitivity/specificity/time to result), antifungal medication and differential length-of-stay and mortality by appropriate treatment timing. Results: The model estimates a hospital with 5100 annual high-risk patients could possibly save $5,858,448 with T2Candida versus BC, a 47.6% decrease in candidemia diagnosis and treatment budget ($1149/patient tested), while averting 60.6% of candidemia-related mortality. Conclusion: Hospitals may observe lower candidemia-related inpatient costs and mortality with rapid Candida diagnosis.
