Abstract: Background: Patients older than 65 years of age with an anticipated life-expectancy of 12 months or less may have complex medication regimens and an increased risk of adverse drug reactions, and drug-drug interactions. Within the Department of Veterans Affairs, a commonly used medication optimization model is known as the VIONE methodology. Objective: This project aimed to pilot implementation of board-certified clinical pharmacist practitioners utilizing the VIONE model within a patient-aligned care team targeting patients 65 years of age and older. Methods: The population was identified through the VIONE dashboards. Veteran inclusion criteria included five or more medications, a VIONE risk score of 5 or greater, and CAN scores of greater than 90. The project team reached out via telephone to the patients for a medication regimen review and a 14-day follow-up call. Primary outcomes were quantity of medications discontinued per patient, classes of medications that were discontinued, number and encounter time spent, and cost avoidance over 1 year. Secondary outcomes were VIONE classification of medications, VIONE discontinuation reason, number of recommendations given and accepted by primary provider, and safety analysis. Results: There were 53 patients who were successfully contacted via telephone. The top four most discontinued medication classes included 1) vitamins/supplements, 2) ophthalmology medications, 3) gastrointestinal medications, and 4) non-controlled analgesic medications. During the project period the potential cost avoidance over 1 year was $17,716. Conclusion: This project demonstrated that usage of VIONE methodology ensures medication optimization with minimal harm and provides significant cost savings in the ambulatory care setting.
