Different linezolid antimicrobial susceptibility testing (AST) methodologies yield varying results. In 2018, we transitioned our linezolid AST methodology from the Etest to Vitek 2. We sought to evaluate the impact of this change on antibiotic use among 181 inpatients with VRE infections. The transition from Etest to Vitek 2, resulted in an increase in linezolid susceptibility (38% versus 96%, p<0.001) and a reduction in time to active antibiotic therapy (3 versus 2.6 days, p=0.007).
