A randomised controlled trial on the effectiveness of a home-based self-management programme for community-dwelling patients with myocardial infarction

Abstract

Aim:

To examine the effectiveness of a four-week home-based self-management rehabilitation programme on health-related quality of life, anxiety and depression levels, cardiac risks and unplanned visits to the health services among community-dwelling patients with myocardial infarction.

Methods:

A randomised controlled trial with repeated measurements was used. A convenience sample of 128 patients with myocardial infarction was recruited from outpatient cardiology clinics at a tertiary hospital in Singapore. Participants were randomly assigned to the intervention group or control group. The outcomes were measured using Short Form 12-item Health Survey Version 2, Myocardial Infarction Dimensional Assessment Scale, and Hospital Anxiety and Depression Scale. The cardiac physiological risk parameters and number of unplanned health service use were also assessed. Data were collected at baseline, and at four weeks and 16 weeks from the baseline.

Results:

Over the 16 weeks, the two groups reported significant differences in physical activity (F = 4.23, p = 0.02), dependency (F = 5.16, p = 0.01), concerns over medication (F = 3.47, p = 0.04) on MIDAS, anxiety level (F = 3.41, p = 0.04) and body mass index (F = 3.12, p = 0.04). A significant difference was also found in unplanned cardiac-related emergency room visits (χ² = 6.64, p = 0.036) and medical consultation (χ² = 9.67, p = 0.046) at the 16-week study point.

Conclusion:

The study may provide a useful tool to help health care professionals to meet the cardiac rehabilitative care needs of community-dwelling patients with myocardial infarction in Singapore.
