Effectiveness of the Self-Care Support Program for People with Acute Coronary Syndrome: A Quasi-experimental Study

Acute coronary syndrome is a chronic illness that influences physical and psychological health and well-being and requires continuous treatment and effective self-care. This two-group quasi-experimental study investigated the effectiveness of the Self-Care Support Program for People with Acute Coronary Syndrome. Sixty participants were purposively recruited from medical wards of a university-affiliated hospital in Bangkok, Thailand. A Self-Care Support Program based on Orem's self-care theory was integrated with a motivational interviewing approach. The experimental group (n = 30) received the 4-week intervention program with the usual care, while the comparison group (n = 30) received only usual care. Instruments for data collection included a Demographic and Health Data Form, the Self-Care Behavior for Acute Coronary Syndrome Questionnaire, the Veterans Specific Activity Questionnaire, and the Rehospitalization Record Form. Data analysis was performed using descriptive statistics, Chi-square test, Fisher's exact test, and two-way repeated measures analysis of variance. Results revealed that the experimental group had significantly improved self-care behavior and functional ability immediately and four weeks after program completion (week 8), compared to the comparison group. There was no difference in rehospitalization between the two groups. Nurses with advanced skills in motivational training can use this program to promote effective self-care practices, improve functional ability, and reduce rehospitalization. Further study using randomized controlled trials and other settings is needed before it can be widely used.
