Brief summary

The proportion of patients achieving the therapeutic and optimal exposure when the plasma concentrations are above the MIC for 100% of the dosing interval. Trough plasma concentration levels will be measured.

Detailed description

The proportion of patients achieving PK/PD index: 100% fT>4xMIC (Ctrough >4xMIC), CRP normalisation (days, <10 mg/L), PCT normalisation (days, <0.5), WBC normalisation (days, <10000 /µl), All-cause mortality (within 30 days or until hospital discharge), Adverse events (every day), Microbiological eradication rate (in different time points: 1st day, 2nd day, 3rd day, 5th day), Clinical response (resolution or improvement or failure), Clinical success (Time in days when clinical succes or resolution is achieved), Treatment failure (Number of patients, for whom the β-lactam antibiotic had to be stopped due to the clinical deterioration and/or antibiotic resistance.), Duration of the antibiotic (days), Length of PICU/NICU stay (days), Length of hospital stay (LOS) (days)
