Abstract
Background: Time to bloodstream clearance is a critical prognostic indicator in various infections, yet limited data exist on the relationship between time to mycological clearance and outcomes in candidemia. This study aimed to assess the association between the duration of candidemia and outcomes in adult, hospitalized patients receiving empiric echinocandin treatment across U.S. hospitals.
Methods: A retrospective, multi-center study using the PINCI AI Healthcare Database (1/2016-4/2019) was conducted. Inclusion criteria: hospitalized adults (≥18 years) with Candida sp. identified on a clinical blood culture who received empiric echinocandin therapy (±2 days of index Candida sp. blood culture) for ≥ 3 days. Outcomes assessed were in-hospital mortality, length of stay (LOS), and hospital costs. The associations between increasing duration of candidemia relative to a single day of candidemia and outcomes were examined.
Results: A total of 867 patients met the criteria. Multivariable analysis showed that patients with candidemia lasting more than one day had significantly higher mortality, longer LOS, and higher hospital costs compared to those with only one day of candidemia. For each additional day of candidemia, the adjusted odds of in-hospital mortality increased by 3%, the adjusted median hospital length of stay post index collection day increased by 1.0 days, and the adjusted median total costs post index collection day increased by $3006.
Conclusion: Prolonged candidemia is associated with worse patient outcomes and higher healthcare costs. Further large-scale studies are needed to confirm these findings given the exploratory and observational nature of this study.
