Model-informed Precision Dosing of Vancomycin in Adults

Phase 4
Completed
Conditions
Vancomycin
Interventions
Device: Vancomycin model-informed precision dosing
Registration Number
NCT05535075
Lead Sponsor
University Hospital, Ghent
Brief Summary

The overall objective of this project is to investigate the utility of model-informed precision dosing (MIPD) of vancomycin in non-critically ill adults. This evaluation includes a comparison with the more standard approach on clinical and patient-oriented measures.

Detailed Description

Vancomycin is an antibiotic with a narrow therapeutic-toxic margin. This means that the minimum and maximum target blood target levels differ little from each other. Too low concentrations will reduce the effect of the antibiotic; higher concentrations may result in serious side effects, including renal toxicity. Vancomycin dosing tailored to the individual patient is challenging.

Currently, the vancomycin dose is adjusted based on a measured vancomycin blood concentration (if too high or too low). Despite this measurement, quickly achieving target concentrations remains a major challenge.

This multicenter, individual randomized study investigates the added value of a user-friendly computer program for calculating the vancomycin dose in non-critically ill adults, compared to the current standard-of-care. Specifically, the investigators will study whether the use of this computer program leads to a shorter time to reach target concentrations, a reduction in the number and severity of side effects on the kidney and a reduction in patient burden.
