Improving Adherence to Post PCI Antiplatelet Therapy in Minority Populations
In Brief
A clinical study evaluating Motivational Interviewing (MINT) and Mailed DVD for Coronary Artery Disease. Completed, enrolled 452 participants across 1 site.
Detailed Summary
The purpose of this study is to evaluate if the use of a phone based motivational interviewing among minority populations who received a coronary stent can improve adherence to antiplatelet agents from approximately 51% to 66% (15 percentage point increase) at 12 months post stent placement when compared to a mailed educational DVD.

Timeline
Interventions
We will hire a Latino and an AA nurse to deliver the interventions and will match their race/ethnicity with that of the subject. Past experience suggests that at 4-7 calls per subjects each lasting about 30-45 minutes, a nurse can carry a caseload of about 125-150 subject (we propose 125 per nurse) Each telephone encounter will have a patient centered approach having the following basic structure and goals: a)Establishing a connection and reinforcing autonomy b)Empathizing with ambivalence and rolling with resistance.c)Coach the subject towards expressions of commitment.
The DVD will have a documentary format that will engage subjects as the portrayed real patients relate their struggles and successes, that will entertain and ultimately motivate subjects to succeed in a similar way as the role models in the video. That personal connection will activate patients to address their own adherence issues and will show real life ways to deal with the health behaviors recommended post PCIS. Key concepts regarding adherence to medications and other behaviors will be imbedded in the story telling. The DVD will also feature a humanistic perspective of a cardiologist talking about his concerns for his patients that do not adhere to the antiplatelet therapy, the difficulties that his patients face, and the merit of the success stories he witnesses.
