ABSTRACT
PURPOSE: Poor adherence to cardioprotective medications after acute coronary syndrome (ACS) hospitalization is associated with increased risk of rehospitalization and mortality. Clinical trials of multifaceted interventions have improved medication adherence with varying results. Patients' perspectives on interventions could help researchers interpret inconsistent outcomes. Identifying factors that patients believe would improve adherence might inform the design of future interventions and make them more parsimonious and sustainable. The objective of this study was to obtain patients' perspectives on adherence to medical regimens after experiencing an ACS event and their participation in a medication adherence randomized control trial following their hospitalization. PATIENTS AND METHODS: Sixty-four in-depth interviews were conducted with ACS patients who participated in an efficacious, multifaceted, medication adherence randomized control trial. Interview transcripts were analyzed using the constant comparative approach. RESULTS: Participants described their post-ACS event experiences and how they affected their adherence behaviors. Patients reported that adherence decisions were facilitated by mutually respectful and collaborative provider-patient treatment planning. Frequent interactions with providers and medication refill reminder calls supported improved adherence. Additional facilitators included having social support, adherence routines, and positive attitudes toward an ACS event. The majority of patients expressed that being active participants in health care decision-making contributed to their health. CONCLUSION: Our findings demonstrate that respectful collaborative communication can contribute to medication adherence after ACS hospitalization. These results suggest a potential role for training health-care providers, including pharmacists, social workers, registered nurses, etc, to elicit and acknowledge the patients' views regarding medication treatment in order to improve adherence. Future research is needed with providers to understand how they elicit and acknowledge patients' views, particularly in the face of nonadherence, and with patients to understand how to empower them to share their opinions with their providers.
ABSTRACT
BACKGROUND: Adherence to cardioprotective medications in the year after acute coronary syndrome hospitalization is generally poor and is associated with increased risk of rehospitalization and mortality. Few interventions have specifically targeted this high-risk patient population to improve medication adherence. We hypothesize that a multifaceted patient-centered intervention could improve adherence to cardioprotective medications. METHODS AND RESULTS: To evaluate this intervention, we propose enrolling 280 patients with a recent acute coronary syndrome event into a multicenter randomized, controlled trial. The intervention comprises 4 main components: (1) pharmacist-led medication reconciliation and tailoring; (2) patient education; (3) collaborative care between pharmacist and primary care provider/cardiologist; and (4) 2 types of voice messaging (educational and medication refill reminder calls). Patients in the intervention arm will visit with the study pharmacist ≈1 week post-hospital discharge. The pharmacist will work with the patient and collaborate with providers to reconcile medication issues. Voice messages will augment the educational process and remind patients to refill their cardioprotective medications. The study will compare the intervention versus usual care for 12 months. The primary outcome of interest is adherence using the ReComp method. Secondary and tertiary outcomes include achievement of targets for blood pressure and low-density lipoprotein, and reduction in the combined cardiovascular end points of myocardial infarction hospitalization, coronary revascularization, and all-cause mortality. Finally, we will also evaluate the cost-effectiveness of the intervention compared with usual care. CONCLUSIONS: If the intervention is effective in improving medication adherence and demonstrating a lower cost, the intervention has the potential to improve cardiovascular outcomes in this high-risk patient population.
