Enhancing older Veterans' care: Insights from medication reviews and deprescribing interventions

Patient experience during and after health care is a critical indicator of quality of care that encompasses effective communication, respect, dignity, and emotional support. However, qualitative studies exploring the experiences of older adults after deprescribing interventions are sparse, highlighting a knowledge gap. This project seeks to address this gap by exploring Veterans' experiences during and after a deprescribing intervention provided by a pharmacist. This study aims to: 1. Assess Veteran's experience of the process of their Comprehensive Medication Review and deprescribing intervention visit; 2. Assess the Veteran's experience with the outcomes of their Comprehensive Medication Review and deprescribing intervention.

Data was collected from 17 Veterans through semi-structured interviews using an interview guide. The Veteran Affairs study site utilizes the VIONE polypharmacy risk calculator to identify high-risk Veterans; the majority of these Veterans were on at least 10 medications. The interview transcripts were analyzed using inductive content analysis. Two research team members independently coded the data for categories and themes. Similarities were identified, and any divergence was discussed and resolved. To enhance the validity of the findings, member checking was performed with Veterans to confirm the results.

Most Veterans viewed the process of the pharmacists' visits and recommendations positively. They expressed confidence in pharmacists' knowledge and instructions. They appreciated the clarity of information pharmacists provided about the purpose, proper administration, and interactions of their medications. These enhanced the Veterans' ability to manage their medication regime. They also desired an increased frequency of interactions with their pharmacist due to these positive interactions. Veterans appreciated interprofessional collaboration between pharmacists, physicians, and other providers. Veterans expressed how pivotal lab test results were for evaluating medication recommendations and effectiveness. Most Veterans reported positive outcomes and/or indicated there were no negative effects as a result of their recent medication changes. Some reported seeking additional information from their providers regarding suggested medication changes to validate recommendations. There was some uncertainty about whether there would be follow-up visits with the professional after the medication change and who should initiate this. A minority indicated problems associated with prior medication discontinuation before the deprescribing intervention and how this limited their openness to future opportunities of deprescribing.

This exploration of Veterans' experiences with the process and outcomes of a deprescribing service affirms its importance and overall success in this site as part of the unique publicly funded Veteran healthcare system in the US. Equally important, the positive Veteran response suggests the value of exploring its potential to benefit patients experiencing polypharmacy across a range of other sites and systems.
