Augmented Renal Clearance Using Population-Based Pharmacokinetic Modeling in Critically Ill Pediatric Patients*

The objectives of this study were to: 1) evaluate the prevalence of augmented renal clearance in critically ill pediatric patients using vancomycin clearance; 2) derive the pharmacokinetic model that best describes vancomycin clearance in critically ill pediatric patients; and 3) correlate vancomycin clearance with creatinine clearance estimated by modified Schwartz or Cockcroft-Gault. Design: Retrospective, two-center, cohort study from 2003 to 2016. Setting: Clinical drug monitoring services in the PICUs at two tertiary care, teaching hospitals. Patients: Children from 1 to 21 years old. Interventions: None. Measurements and Main Results: Identify patients with augmented renal clearance (vancomycin clearance ≥ 130 mL/min/1.73 m2 used as definition of augmented renal clearance). Derive final population-based pharmacokinetic model and estimate individual patient pharmacokinetic parameters. Compare estimated glomerular filtration rate (modified Schwartz or Cockcroft-Gault depending on age
