Describe self-reported medication use behaviors and perspectives to identify opportunities for collaborative deprescribing among older cardiovascular patients. Patient survey using convenience sampling. Private cardiology practice in Maricopa County, Arizona, USA. Established patients aged ≥65 years with an active medication list indicating prescription polypharmacy (≥5 medications) and/or use of ≥1 high risk medication (anticoagulant, antiarrhythmic, anti-hypotensive, insulin). Anonymous online survey. Current medication use (prescription and over-the-counter), self-reported medication use behaviors measured by the Adherence to Refills and Medications Scale (ARMS-12), and perspectives on deprescribing. Overall, 138 participants were recruited, with a mean age of 76.7 years. All but two self-identified as Caucasian. Prescription polypharmacy was reported by 80 (58.0 %), with use of 5-9 medications by 66 (47.8 %) and use of ≥10 medications (excessive polypharmacy) by 14 (10.1 %). Approximately one-third (n = 45, 32.6 %) had ARMS = 12, indicating adherence to taking and refilling medications. More than 1 in 10 patients (11.6 %) used >1 high-risk medication. About 4 in 10 (40.6 %) used ≥5 OTC medications. Most highly prioritized reasons for continuing medications were to prolong life (40 %), feel better (17 %), and reduce stroke risk (15 %). Despite 66.7 % of patients indicating taking "just the right amount of medications," willingness to stop ≥1 medication was very high at 80.4 %. Among older cardiovascular patients, prescription polypharmacy is prevalent as are medication use behaviors associated with some degree of nonadherence. Patients are supportive of deprescribing. Prioritizing what matters most to patients and focusing efforts to deprescribe potentially inappropriate medications is recommended.
