Improvement in vancomycin utilization in adults in a Saudi Arabian Medical Center using the Hospital Infection...

Area of Science:

• Pharmacology
• Infectious Diseases
• Clinical Pharmacy

Background:

• Vancomycin is a critical antibiotic for treating serious Gram-positive infections.
• Appropriate utilization of vancomycin is essential to optimize efficacy and minimize resistance.
• Adherence to established guidelines, such as those from the Centers for Disease Control and Prevention (CDC), is crucial for effective vancomycin therapy.

Purpose of the Study:

• To assess vancomycin prescribing patterns based on adapted CDC criteria.
• To evaluate the impact of an educational intervention on vancomycin utilization.
• To determine the effectiveness of pharmacist-led chart review and feedback in improving vancomycin use.

Main Methods:

• A pre- and post-intervention study design was employed over a 3-month period.
• An educational program was implemented to guide vancomycin prescribing.
• Patient charts were reviewed, and feedback was provided to physicians regarding guideline adherence.

Main Results:

• Pre-intervention, only 65% of vancomycin use was appropriate by CDC criteria, with suboptimal dosing and monitoring.
• Post-intervention, compliance with empirical vancomycin use improved significantly from 21% to 85% (P=.0001).
• Appropriate vancomycin use in specific therapy increased to 100%, and trough level monitoring improved from 35% to 67.7% (P=0.0002).

Conclusions:

• Educational initiatives coupled with clinical pharmacist interventions effectively reduce inappropriate vancomycin usage.
• Pharmacist chart review and feedback are valuable tools for enhancing adherence to vancomycin guidelines.
• These strategies contribute to optimizing antibiotic stewardship and patient outcomes.
