Symptom experience as a predictor of cardiac rehabilitation education programme attendance after percutaneous coronary intervention: A prospective questionnaire survey

Despite evidence that participation in cardiac rehabilitation programmes after percutaneous coronary intervention is associated with better clinical outcomes, many patients with coronary artery disease do not participate in such programmes. A traditional educational approach is recommended to provide patients with information regarding the benefits of cardiac rehabilitation in relation to their underlying coronary artery disease and modification of risk factors.

The purpose of this study was to examine the role of patient factors (symptom experience and health belief) on cardiac rehabilitation education programme attendance among Korean patients subjected to percutaneous coronary intervention.

A prospective survey was conducted enrolling 173 patients who underwent percutaneous coronary intervention. Information on symptom experience, health belief (perceived susceptibility/severity/benefits/ barriers) and sociodemographic and clinical characteristics was collected at baseline (after percutaneous coronary intervention). Three to four weeks later, information on disease-related knowledge and health behaviour was compared between cardiac rehabilitation education programme attendees and non-attendees.

Eighty of 173 (46.2%) patients surveyed attended the cardiac rehabilitation education programme. Symptom experience before percutaneous coronary intervention was the most significant predictor of programme attendance (odds ratio=3.46; 95% confidence interval 1.45-8.27), followed by higher perceived socioeconomic status (odds ratio=2.90; 95% confidence interval 1.28-6.58), perceived susceptibility (odds ratio=1.22, 95% confidence interval 1.08-1.39), perceived benefits (odds ratio=1.09; 95% confidence interval 1.02-1.17) and perceived severity (odds ratio=1.04; 95% confidence interval 1.00-1.08). Better disease-related knowledge and health behaviour were significantly associated with cardiac rehabilitation education programme attendance.

This study provides evidence that educational programmes to help improve patients' perceptions of their disease susceptibility and severity, especially health behaviour benefits in patients without symptom experience before percutaneous coronary intervention, are necessary.
