Item Open Access Multifaceted intervention to improve medication adherence and secondary prevention measures after acute coronary syndrome hospital discharge: a randomized clinical trial.(JAMA internal medicine, 2014-02) Ho, P Michael; Lambert-Kerzner, Anne; Carey, Evan P; Fahdi, Ibrahim E; Bryson, Chris L; Melnyk, S Dee; Bosworth, Hayden B; Radcliff, Tiffany; Davis, Ryan; Mun, Howard; Weaver, Jennifer; Barnett, Casey; Barón, Anna; Del Giacco, Eric JImportance
Adherence to cardioprotective medication regimens in the year after hospitalization for acute coronary syndrome (ACS) is poor.Objective
To test a multifaceted intervention to improve adherence to cardiac medications.Design, setting, and participants
In this randomized clinical trial, 253 patients from 4 Department of Veterans Affairs medical centers located in Denver (Colorado), Seattle (Washington); Durham (North Carolina), and Little Rock (Arkansas) admitted with ACS were randomized to the multifaceted intervention (INT) or usual care (UC) prior to discharge.Interventions
The INT lasted for 1 year following discharge and comprised (1) pharmacist-led medication reconciliation and tailoring; (2) patient education; (3) collaborative care between pharmacist and a patient's primary care clinician and/or cardiologist; and (4) 2 types of voice messaging (educational and medication refill reminder calls).Main outcomes and measures
The primary outcome of interest was proportion of patients adherent to medication regimens based on a mean proportion of days covered (PDC) greater than 0.80 in the year after hospital discharge using pharmacy refill data for 4 cardioprotective medications (clopidogrel, β-blockers, 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors [statins], and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers [ACEI/ARB]). Secondary outcomes included achievement of blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) level targets. RESULTS Of 253 patients, 241 (95.3%) completed the study (122 in INT and 119 in UC). In the INT group, 89.3% of patients were adherent compared with 73.9% in the UC group (P = .003). Mean PDC was higher in the INT group (0.94 vs 0.87; P< .001). A greater proportion of intervention patients were adherent to clopidogrel (86.8% vs 70.7%; P = .03), statins (93.2% vs 71.3%; P < .001), and ACEI/ARB (93.1% vs 81.7%; P = .03) but not β-blockers (88.1% vs 84.8%; P = .59). There were no statistically significant differences in the proportion of patients who achieved BP and LDL-C level goals.Conclusions and relevance
A multifaceted intervention comprising pharmacist-led medication reconciliation and tailoring, patient education, collaborative care between pharmacist and patients' primary care clinician and/or cardiologist, and voice messaging increased adherence to medication regimens in the year after ACS hospital discharge without improving BP and LDL-C levels. Understanding the impact of such improvement in adherence on clinical outcomes is needed prior to broader dissemination of the program.Trial registration

Cardiovascular quality and outcomes, 2012-07) Lambert-Kerzner, Anne; Del Giacco, Eric J; Fahdi, Ibrahim E; Bryson, Chris L; Melnyk, S Dee; Bosworth, Hayden B; Davis, Ryan; Mun, Howard; Weaver, Jennifer; Barnett, Casey; Radcliff, Tiffany; Hubbard, Amanda; Bosket, Kevin D; Carey, Evan; Virchow, Allison; Mihalko-Corbitt, Renee; Kaufman, Amy; Marchant-Miros, Kathy; Ho, P Michael; Multifaceted Intervention to Improve Cardiac Medication Adherence and Secondary Prevention Measures (Medication) Study InvestigatorsBackground
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.
