Shared Decision-making: Effects on Cardiac Risk Factor Modification Behavior

Overview

Decision Aids (DA) to inform patients about health care options and help them to participate in their care choices are widely advocated. The main argument for offering patients a choice is that patients' preferences vary, and health professionals cannot always know what is "best" for an individual, specially when different outcomes have different benefits and risk profiles. The standard modes of treatment for patients with coronary artery disease (CAD) are coronary artery bypass graft (CABG) surgery, medication, and angioplasty. All three treatments for CAD work better when combined with cardiac risk factor modification behavior (CRFMB). CRFMB is important for the general public, but it is even more important for people with CAD because people with CAD have more at stake. In this RCT study we will evaluate the effectiveness of a CAD-DA with and witout an additional decision counseling program (DCP) on health outcomes and quality of life to improve enhancement of adherence to cardiac risk modification behavior. The CAD-DA is developed by the Ottawa Health Research Institute and Division of Clinical Epidemiology at Montreal General Hospital, for CAD patients facing the decision of making lifestyle changes to lower their cardiac risk factors. It provides patients with information about what they can you do to prevent the disease from progressing. The DCP is designed to systematically guide patients through the process of deciding what cardiac risk modification behaviors are important for them to carry out. A RCT where 360 CAD patients \> 18 of age scheduled for an angiogram at Rikshospitalet University Hospital in Norway (RH) will be randomly assigned to: (1) CAD-DA group where subjects will receive, for take home, the CAD-DA prior to their scheduled angiogram; (2) DCP group where subjects in addition to the CAD-DA will receive an individual decisional counseling program (DCP) from a trained nurse counselor in their homes prior to their angiogram; and (3) the control group who will receive "usual care". Data will be collected at four points: at the initial visit (T1), 2 months (T2), 4 months (T3) and 6 (T4) months after angiogram
