Decisional Quality for Patients With Stable Coronary Artery Disease

For patients with coronary artery disease (CAD), having a stent (or percutaneous coronary intervention or PCI) involves both risk and inconvenience, and thus it represents a classic "preference-sensitive" situation, in which treatment decisions should be aligned with the patient's preferences.

In this project the investigators will develop the first comprehensive, patient-reported measure of decisional quality for CAD that is feasible to implement in a variety of settings. The investigators will accomplish this by: 1) Identifying the key elements to capture decisional quality and identifying candidate questions to address these elements, using patient and expert feedback; 2) Pilot testing a preliminary instrument in a diverse patient population to assess measurement properties and select a reduced set of candidate questions for further testing; and 3) Establish the reliability and validity of a new comprehensive decisional quality measure for single and repeated examinations. This will result in a multidimensional decisional quality instrument for patients with CAD that will be ready for implementation into routine care.
