Exploring Patients' Reasons for Discontinuance of Heart Medications

Abstract

The most common reason for CLT discontinuance was adverse effects that were painful and interfered with daily life. Less common reasons for discontinuance were prescription confusion, cost, mistrust in medicines/healthcare system, and preference for alternative therapies. Reasons for clopidogrel discontinuance were duration confusion, adverse effects, and cost. Although doctors stopped patients' clopidogrel in preparation for surgery, doctors conceded to discontinuance of CLT for patients who experienced adverse effects after trying 2 to 3 different CLTs. Patients who discontinued CLT were more likely to believe that they did not need the treatment than do patients who discontinued clopidogrel. Clinicians should be aware that reasons may vary across patients and medication class for prematurely stopping therapy; thus, proactive interventions should be targeted to address these differences. Identifying at-risk patients for targeted interventions to prevent premature cardiac medication discontinuation is vital.
