  In beta-lactam therapy, investigation of the pharmacokinetic-pharmacodynamic (PK-PD) relationship has provided surrogate makers to predict clinical outcome. This study was designed to verify the therapeutic efficacy and clinical utility of beta-lactam therapeutic drug monitoring (TDM) in critically ill patients using high-performance liquid chromatography (HPLC). This cohort study included 13 patients who were intravenously administered ceftazidime (n = 6), cefepime (n = 1), imipenem (n = 1), meropenem (n = 1), or piperacillin (n = 4). Blood samples were collected at 3 time points fitted to a 1-compartment model, and concentrations were determined using HPLC. The PK-PD target was the percentage of the dosing interval during which the antibiotic concentration exceeded the minimum inhibitory concentration for the pathogens (%T > MIC), which is 50% for penicillins (piperacillin), 60% ..
