Abstract
Heart failure affects 5 million North Americans every year (Inglis et al., 2006). It is the leading cause of hospitalization for patients 65 years of age or older, and up to 50% of patients are rehospitalized in 6 months (Fonarow, 2004). Half of rehospitalizations result from nonadherence to diet, medications, or both (Mueller, Vuckovic, Knox, & Williams, 2002).
