Prediction of Vancomycin Area Under the Curve With Trough Concentrations Only: Performance Evaluation of Pediatric Population Pharmacokinetic Models
To evaluate the predictive performance of population pharmacokinetic models using only trough concentrations to estimate the 24-hour area under the concentration-time curve (AUC24h) for vancomycin in pediatric patients.
Key Findings:
Trough concentration-based AUC24h estimation showed similar precision to peak and trough concentration-based estimation.
For cohort A, models by Chen, Colin, and Mehrotra had the best performance with low relative bias and rRMSE.
For cohort B, models from Alsultan and Lv demonstrated the lowest relative bias and rRMSE.
Interpretation:
Trough concentration-based estimation of AUC24h is feasible for optimizing vancomycin dosing in pediatric patients, supporting the use of selected models for model-informed precision dosing.
Limitations:
Retrospective study design may introduce bias.
Further investigation into clinical outcomes is needed.
Conclusion:
The study supports the use of trough concentrations for AUC24h estimation in pediatric vancomycin therapy, highlighting the need for further research on clinical outcomes.
