Higher target attainment for B-lactam antibiotics in patients with Gram-negative bloodstream infections when four times actual minimum inhibitory concentrations and epidemiological cutoff values are applied compared to clinical breakpoints
IntroductionBeta-lactam antibiotics are essential in the treatment of Gram-negative bloodstream infections. The effect of beta-lactam antibiotics depends on the time of unbound antibiotic concentration above the minimal inhibitory concentration (MIC). An antibiotic concentration above MIC during the whole dosing interval (100% ƒT > MIC) has been suggested as a target for severe infections. The aim
