RESUMO
AIMS: A randomized controlled trial was conducted to examine the effects of a home-based music-paced physical activity programme guided by Information-Motivation-Strategy (IMS) model and Self-determination theory on exercise-related outcomes for patients with coronary heart disease (CHD) after cardiac rehabilitation (CR). METHODS AND RESULTS: A total of 130 patients with CHD from a regional CR centre in Hong Kong were recruited and randomly allocated into intervention (n = 65) or control groups (n = 65). The intervention group received theory-guided practical sessions on performing prescribed home-based physical activity with individualized synchronized music, and follow-up telephone calls. The primary outcome was exercise capacity. Secondary outcomes included exercise self-efficacy, physical activity level, and exercise self-determination. Data were collected at baseline, 3 months, and 6 months after study entry. The generalized estimating equations model was used to assess the intervention effects. Patients with CHD in the intervention group demonstrated significantly greater improvements in exercise capacity at 3 months [ß = 35.68, 95% confidence interval (CI) 2.69-68.68, P = 0.034] and significantly improved exercise self-efficacy at 6 months (ß = 3.72, 95% CI 0.11-7.32, P = 0.043) when compared with the control group. However, no significant group differences were found in physical activity level and exercise self-determination. CONCLUSION: The study findings provide evidence on an innovation on improving the exercise capacity and exercise self-efficacy of patients with CHD. The music-paced physical activity guided by the IMS model and Self-determination theory requires further investigation on its long-term effects in future studies. CLINICAL TRIAL REGISTRATION: ChiCTR-IOR-17011015.

AIM: To investigate the determinants of exercise capacity in postcardiac rehabilitation patients with coronary heart disease (CHD). DESIGN: A cross-sectional design was used. METHODS: This study analysed the cross-sectional data from the baseline assessment of 130 CHD patients who participated in a longitudinal randomized controlled trial of music-paced physical activity intervention for CHD patients (ChiCTR-IOR-17011015) (September 2017 to February 2019). Exercise capacity was measured by using the 10-metre incremental shuttle-walk test. The amount of physical activity, exercise self-determination and exercise self-efficacy were measured by validated instruments. Participants' anthropometric parameters (body mass index, body fat mass percentage and waist circumference) were measured. Hierarchical regression analyses were used to identify the factors influencing exercise capacity. RESULTS: The mean incremental shuttle-walk test distance was 493.00 ± 180.04 m. The factors significantly associated with exercise capacity were age (ß = -.42), female (ß = -.35), body mass index (ß = -.25) and exercise self-efficacy (ß = -.20). These factors accounted for 56.5% of the total variance of exercise capacity.

UNLABELLED: Limited accessibility to resuscitation equipment and non-standardized instrument layout in trolleys would cause difficulty for the team members to access appropriate emergency equipment for delivering prompt resuscitation service in Tung Wah Eastern Hospital (TWEH). Improvement initiatives were implemented in September 2012 after endorsement by the resuscitation subcommittee: (i) standardization and installation of resuscitation equipment including resuscitation trolleys, emergency drug kits, automatic emergency defibrillators, designated response team (DRT) kit; (ii) guidelines revision involves the workflow, staff deployment, and designated areas for resuscitation during different service hours and (iii) staff training by workshop and video. Periodic resuscitation drill was held to monitor staff performance after training and the debriefing provided a chance for discussion and feedback from frontline staff. The compliance audit result for this exercise and the staff performance in the drills were improved, showing that the initiatives were successful.
