Antimicrobial Agents and Chemotherapy · 10.1128/AAC.01708-10

Structure

A one-compartment model, driven by weight and creatinine clearance.

Study population

Critically ill patients — Belgium and Europe. Fitted to 206 patients and 579 concentration observations.

Covariate As reported
Age 58.1 ± 14.8 yr
Weight 74.8 ± 15.8 kg
BMI 25.9 ± 5.4 kg/m²
CrCl 90.7 ± 60.4 mL/min
