Effectiveness of an Education Intervention Among Cardiac Rehabilitation Patients in Canada: A Multi-Site Study

Although patient education is considered a core component of cardiac rehabilitation (CR) programs, to our knowledge, no educational program designed for CR has been standardized in Canada. This absence of standardization may be due to a lack of reliable resources to educate these patients. The objective of this study was to assess the effectiveness of an education intervention in improving knowledge and health behaviours among CR patients in 3 sites in Canada.

CR patients were exposed to an evidence- and theoretically based comprehensive education intervention. Patients completed surveys assessing knowledge, physical activity, food intake, self-efficacy, and health literacy. All outcomes were assessed pre- and post-CR. Paired t tests were used to investigate variable changes between pre- and post-CR, Pearson correlation coefficients were used to determine the association between knowledge and behaviours, and linear regression models were computed to investigate differences in overall post-CR knowledge based on participant characteristics.

A total of 252 patients consented to participate, of whom 158 (63.0%) completed post-CR assessments. There was a significant improvement in patients' overall knowledge pre- to post-CR, as well as in exercise, food intake, and self-efficacy (P < 0.05). Results showed a significant positive correlation between post-CR knowledge and food intake (r = 0.203; P = 0.01), self-efficacy (r = 0.201; P = 0.01), and health literacy (r = 0.241; P = 0.002). Education level (unstandardized beta = -2.511; P = 0.04) and pre-CR knowledge (unstandardized beta = 0.433; P < 0.001) were influential in changing post-CR knowledge.

In this first-ever multi-site study focusing on patient education for CR patients in Canada, the benefits of an education intervention have been supported.
