Secondary Event Prevention Using Population Risk Management After PCI and for Anti-Rheumatic Medications
Ischemic heart disease (IHD) and its treatment carry profound public health and economic implications. Among Veterans, IHD represents one of the most common causes of death and disability, with over 500,000 affected individuals' annually. Rheumatic disease, though far less common than IHD can affect multiple organ systems and requires therapies costing in excess of $50,000 a year. Optimal treatment of Veterans with IHD and rheumatic disease requires a number of medications to maintain or improve health. Not taking medications as prescribed, however, is common and increases the risk of subsequent adverse events (cardiac death and myocardial infarction [MI]). 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.
Secondary Event Prevention Using Population Risk Management After PCI
Ischemic heart disease (IHD) and rheumatic diseases are both pervasive, expensive, and results in grave health consequences. IHD affects an estimated 15.4 million Americans 20 years of age-representing 6.4% of the adult population. The direct and indirect cost of IHD has been estimated at $195.2 billion, with a doubling of cost projected by 2030.5 Similarly, the direct cost to the U.S. workforce for rheumatoid arthritis alone approaches $5.8 billion yearly.
Widely-accepted national evidence-based guidelines support the use of cardio-protective medications to reduce the risk of adverse consequences resulting from IHD and disease modifying anti-rheumatic medications (DMARDs) to reduce the risk of adverse consequence in rheumatic diseases. For example, numerous rigorously conducted randomized trials show that statins improve outcomes and reduce mortality in patients with established cardiovascular disease (i.e., secondary prevention), including those undergoing percutaneous coronary interventions (PCI). The use of statins and beta-blockers have been repeatedly demonstrated to be cost-effective in lowering cardiovascular event (CVE) rates, in part by their effects on cholesterol, and blood pressure, respectively. Accordingly, the most recent VA performance measures and American Heart Association guidelines encourage the use of statins in patients with atherosclerotic disease; beta-blockers in subjects with left ventricular systolic dysfunction (ejection fraction less than 40%), prior MI, or blood pressure of 140/90 or greater; and clopidogrel following any acute coronary syndrome (ACS) or PCI with stent. The rheumatology literature provides similar evidence for the benefit of DMARDs in rheumatic diseases, and guidelines strongly endorse their use.
Unfortunately, non-adherence to medications is common, and increases the risk of poor outcomes. The investigators' 2011 national preliminary data from VA cardiac catheterization laboratories (CCLs) demonstrate that over 6300 patients experienced at least one refill gap of >= 7 days for statins in the year following PCI. The mean proportion of days covered (PDC) for these patients was only 75%-below the PDC threshold of 80% that typical defines adherent patients, based on the empiric evidence for effectiveness of medications at this cut-point. Non-adherent patients were present at all CCLs without substantial variation in mean PDC by center, suggesting a global problem.
Systematic problems underlie and contribute to non-adherence to medications. Usual care of IHD and rheumatic disease patients is encumbered by systematic deficiencies including: passive monitoring (contact with patients only when initiated by the patient) and inefficiency (time-consuming patient-by-patient approach, rather than through population management). The proposed intervention addresses both the complex patient-specific factors (emphasizing forgetfulness and carelessness) and the systematic inadequacies using a multi-modal, escalating approach.
- To assess the effectiveness of a multi-faceted patient-centered intervention versus usual care in improving medication adherence as measured by proportion of days covered (PDC, primary outcome). This will be tested among IHD patients for statins, beta-blockers and clopidogrel in the year after PCI and among rheumatology clinic patients chronically prescribed DMARDs. Hypothesis: The PDC for patients in the intervention arm will exceed the PDC for the usual care arm by a 10% absolute difference.
- (Secondary outcome): To determine the effectiveness of a multi-faceted patient-centered intervention versus usual care in reducing secondary CVEs (myocardial infarction [MI], repeat revascularization [PCI or coronary bypass graft], and all-cause mortality) among IHD patients at 18 months post-PCI and progressive erosive disease demonstrated on plain film radiographs in patients with rheumatic diseases (i.e. "radiographic progression"). Hypothesis: The rate of CVEs and radiographic progression will be 5% relatively lower for patients in the intervention arm compared with usual care.
- (Secondary outcome): To establish the cost to implement and maintain the intervention, above the cost of usual care, as well as the incremental cost effectiveness (ICE; e.g. cost to achieve at 10% improvement in PDC; cost per CVE prevented). Hypothesis: This aim does not posit a hypothesis as the objective is descriptive. The available funding for this project limits this outcome to IHD patients (no rheumatic disease patients will be analyzed according to cost).
