Optimizing Vancomycin dosing in a sample of critically ill patients comparing current practices to individualized dose regimen: A Randomized study.
Background:In 2020, a revised consensus guideline of therapeutic monitoring of vancomycin for serious methicillin-resistant Staphylococcus aureus infections was published, and reviewed by many regulatory authorities Stated that, in patients with suspected or definitive serious MRSA infections, an in...

Objective: Comparing vancomycin AUC24/MIC ratio of patients receiving conventional vancomycin doses to patients receiving individualized doses calculated by pharmacokinetic dosing methods. Methods: A prospective randomized study conducted in the Intensive Care Units (ICU) of two tertiary centers at Baghdad Medical Complex (Baghdad Teaching Hospital and Ghazi Al-Hariri Hospital for Surgical Specialties), Patients were assigned alternately, 30 patients who met inclusion criteria were assigned to the conventional group (group 1), receiving the conventional dose of 1 g of vancomycin every 12 hours or any other dose prescribed by ICU physicians, representing the current practice; and 30 patients were assigned to the interventional group (group 2), where vancomycin dose was calculated by pharmacokinetic dosing method. Results: The target AUC24/MIC Ratio of 400 -- 600 mcg*hr/mL was achieved in 6 (20%) patients of group 1, and 16 (53.33%) patients of group 2, which was statistically significant with P-value 0.000. Conclusions: Individualized vancomycin dosing improved achievement of the therapeutic AUC24/MIC target versus conventional dosing (53.3% vs 20.0%) but was associated with increased nephrotoxicity. pubtype: Academic Journal doctype: pictorial research tables/charts randomized controlled trial Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
