Student Pharmacist Led Fish Oil Deprescribing Initiative at a Veterans Affairs Hospital and Rural Clinics

Abstract

Background: Polypharmacy impacts one-third of older adults and has been shown to lead to adverse health effects. One contributor to polypharmacy includes omega-3 fatty acid (fish oil) due to the lack of evidence supporting clinical benefit. Pharmacists can identify and reduce polypharmacy, inspiring this student led deprescribing initiative to introduce a standard of care process for deprescribing fish oil. Purpose/Objectives: The overall objectives of this evaluation are to assess the need for a fish oil deprescribing process, to analyze the role of student pharmacists in deprescribing, and to evaluate the effectiveness of a fish oil deprescribing service. Methods: This project integrated three doctor of pharmacy students in their third year of pharmacy school who were enrolled in a yearlong class about improving healthcare for rural populations and the quality improvement research process. Four primary care clinic patient panels who were prescribed fish oil were assessed. Chart reviews were conducted, and patients were contacted to deprescribe their fish oil by the student and offer statin or lipid therapy modifications, if applicable. Results: A generated report identified 106 patients who had active prescriptions for fish oil. After application of exclusion criteria, 68 patients were included in the evaluation. A total of 76.2% of patients accepted at least one therapy modification offered by the pharmacy student. Conclusion: This evaluation demonstrates the positive impact of the integration of student pharmacists for deprescribing in a primary care setting. Opportunities exist to further explore student pharmacist roles within ambulatory care clinic models.
