To evaluate the impacts of fluconazole minimum inhibitory concentration (MIC) according to primary antifungal agents on Candida glabrata bloodstream infection (BSI), a multicenter retrospective cohort study was conducted in Korea, concerning the time period from January 2010 to February 2016. A total of 197 adult patients with C. glabrata BSI were included in the study, and neutropenia (P = 0.026), APACHE II score (P = 0.004), and fluconazole resistance (HR 3.960, 95% CI 1.395-11.246, P = 0.010) were associated with 30-day mortality in multivariate analysis. In subgroup analysis, fluconazole MIC = 32 μg/mL in the azole-treated group (HR 6.691, 95% CI 1.569-28.542, P = 0.010) and fluconazole MIC ≥ 64 μg/mL in the non-azole-treated group (HR 3.337, 95% CI 1.183-9.411, P = 0.023) showed the highest hazard ratio (HR) for 30-day mortality. Increased fluconazole MIC was associated with poor outcome both in azole- and non-azole-treated patients with C. glabrata BSI.
