Abstract
Background
Physical activity following coronary artery bypass graft (CABG) surgery is linked to improved short and long-term outcomes. However, uptake of cardiac rehabilitation programs is low following CABG surgery. Psychosocial interventions have been identified as possible ways to increase exercise participation and adherence.
Objectives
To undertake a systematic review to investigate the effectiveness of psychosocial interventions on improving engagement in physical activity and optimizing physical function during the first three months following CABG surgery. The secondary aim was to identify the self-management strategies and/or behavior change techniques that were incorporated into post-CABG rehabilitation programs described in the literature.
Methods
A search strategy was developed and used across nine electronic databases. Records were screened against eligibility criteria developed by the research team. Methodological quality was assessed using the Joanna Briggs Institute checklists.
Results
Eighteen articles were included in the review. All used at least one behavioral change technique; 2/18 included self-management strategies. Sixteen studies demonstrated an improvement and there was a significantly superior effect of the intervention on physical activity engagement or physical function compared to usual care in 11/18 studies. The effect was superior in females only, in 1/11 studies. Patient education was the predominant psychosocial intervention.
Conclusions
Whilst psychosocial interventions demonstrated benefits for patients, the interventions used did not equip the participants with the skills required to optimize self-management. Further studies to investigate the effectiveness of self-management strategies are required to determine the most effective strategies to improve physical activity levels, and physical functioning in early rehabilitation post-CABG.
