The effect of a self-help psychoeducation programme for people with coronary heart disease: A randomized controlled trial

Aim: To examine the effect of a self-help psychoeducation program for people with coronary heart disease in Singapore. Background: Cardiac rehabilitation has shown benefits for mitigating many cardiac risk factors and can lead to improvement in health-related quality of life and psychological well-being in people with heart disease. However, traditional hospital-based cardiac rehabilitation faces substantial challenges. A self-management cardiac rehabilitation program offers an avenue to increase uptake and empowers patients to manage their condition at home. Design: A two-arm, randomized controlled trial. Methods: A total of 129 patients with coronary heart disease were recruited from an outpatient clinic in a public hospital in Singapore from April 2015-January 2016. They were randomly assigned to the intervention group or the control group. Participants in the intervention group received the 4-week home-based self-help psychoeducation program. Outcomes were measured at baseline and at 4 weeks and 16 weeks from the baseline. Results: There were no significant differences in health-related quality of life, psychological status (i.e., perceived stress level, anxiety, and depression levels), or cardiac physiological risk parameters between the intervention and the control groups immediately after the program or at different time points. There was also no significant difference in unplanned health service use at the 16 week posttest point between the two groups. Conclusions: This study did not find any significant effect of our program on outpatients with coronary heart disease. Nonetheless, findings on participant characteristics may offer healthcare professionals valuable insights to help facilitate future development of an effective cardiac rehabilitation program catered to outpatients with coronary heart disease. Trial registration: The study has been registered with ISRCTN registry. The trial registration number is ISRCTN15839687.
