To improve medication adherence rates and the cardiac health of Veterans with IHD, the investigators propose to test a medication adherence intervention. Known as VA SEPPRMACI-ARM (Secondary Event Prevention using Population Risk Management After PCI and for Anti-Rheumatic Medications), this intervention will consist of: proactive real-time adherence monitoring of patients and targeting of individuals if they have not refilled their medication a given number of days after it was due for refill. The intervention will employ a tailored, escalating-intensity approach which begins with some combination of personalized short messaging service (SMS) text messages and interactive voice response (IVR) telephone technology, depending on patient preference. Patients not completing SMS and then IVR by not refilling their medication (or declining SMS and not completing IVR) escalate to a trained research interventionalist. The interventionalist will contact the patient and address adherence barriers based on the dimensions outlined by the World Health Organization (WHO) that are specific to each patient. The investigators will test the intervention on IHD patients who have recently undergone PCI-a cardiac procedure commonly used among IHD patients to improve the heart's blood flow and in patients starting anti-rheumatic medication. The investigators will test the intervention at four VA Cardiac Catheterization Laboratories (CCLs) and have 12 sites serving as usual care controls.
