Abstract 3092: A Psychoeducation Trial for People with Chronic Stable Angina
AIM: Chronic stable angina (CSA) is a cardinal symptom of coronary artery disease (CAD) and has a major negative impact on health-related quality of life (HRQOL) including general health status, and ability to self-manage. Current secondary prevention approaches lack adequate scope to address CSA as a multidimensional persistent pain problem. This trial evaluated the impact of a low-cost 6-week angina psychoeducation program (CASMP) on HRQOL, self-efficacy and resourcefulness to self-manage symptoms, and CSA-related costs.
METHODS: Patients (n=130) were randomized to the CASMP or 3-month wait-list control; 117 completed the study. Measures were taken at baseline and 3 months. General HRQOL was measured using the SF-36 and the disease-specific Seattle Angina Questionnaire. Self efficacy, resourcefulness and cost of illness were measured using the Self-Efficacy Scale, the Self-Control Schedule, and the Ambulatory Home Care Record respectively.
RESULTS: The mean age of participants was 68, 80% were male. ANOVA of change scores yielded significant improvements in treatment group physical functioning [F=11.75(1,114), p<0.001] and general health [F=10.94(1,114), p=0.001] aspects of HRQOL. Angina frequency [F=5.60(1,115), p=0.02], angina stability [F= 7.37(1,115), p=0.001], and self-efficacy to manage disease [F=8.45(1,115), p=0.004] were also significantly improved at 3 months. The CASMP did not impact cost of illness. Societal costs for angina were determined to be $12,615 per person per annum (2003 – 2005).
CONCLUSION: These data indicate that the CASMP was effective for improving physical functioning, general health, angina symptoms, and self-efficacy to manage angina at 3 months, and provide prefatory data for long-term evaluation of the CASMP.
