The Efficacy and Economics of Exercise Maintenance Post-Cardiac Rehabilitation - Full Text View

Purpose

The purpose of this study is to develop a new intervention to improve the transition of patients from structured, supervised exercise to self-managed home- or approved community-based exercise programs in an effort to increase maintenance of exercise behaviour post cardiac rehabilitation (CR). The goal of the study is that those receiving the intervention will engage in at least 30 minutes of physical activity at a moderate or vigorous intensity 5 or more days per week, 26 and 52 weeks after CR compared to those in the usual care group. The new intervention will be delivered by trained exercise facilitators (physiotherapists or exercise specialists) and will make use of: small group counseling teleconferences (5 sessions); personal telephone contacts (3 sessions), and community program demonstrations that would facilitate linkages between patients and approved community programs known as Heart Wise Exercise programs available in Ottawa and Toronto. The trial will be conducted at the Minto Prevention and Rehabilitation Centre at the University of Ottawa Heart Institute and the Cardiovascular Rehabilitation and Prevention Centre at the University Health Network (Peter Munk Cardiac Centre [PMCC] and Toronto Rehabilitation Institute [TRI]) sites. The study has a target enrollment of 286 participants.

Primary Outcome Measures:

9-day accelerometer-measured physical activity of moderate and vigorous intensity [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
Physical activity will be measured directly by having participants wear the Actigraph GT3X accelerometer (Actigraph, Pensacola, Florida) over the right hip for a 9-day recording period, excluding periods when they are sleeping, swimming, or bathing. The activity monitor provides measurements including activity counts, energy expenditure, and step counts, in addition to activity intensity levels. Participants will be considered to be maintaining exercise at guideline recommended levels if they undertake ≥ 30 minutes of moderate and/or vigorous intensity physical activity on ≥ five days.

Secondary Outcome Measures:

Symptom limited graded exercise test with electrocardiographic monitoring using a ramp protocol on a treadmill [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
A random sub-sample of participants (N = 124) will complete a symptom limited graded exercise test with electrocardiographic monitoring using a ramp protocol on a treadmill at baseline and at 52 weeks. Exercise tolerance will also be assessed using the Duke Activity Status Index (DASI), a self-administered questionnaire that measures a patient's functional capacity and is used as an estimate of an individual's peak oxygen uptake
Quality of life measured by the the EuroQoL 5D [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
The EQ-5D is the current gold standard measure of generic quality of life, has been used in numerous studies and has been validated in many languages. The EQ-5D consists of 2 pages - the EQ-5D descriptive system and the EQ visual analogue scale. The EQ-5D descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Cardiovascular risk factors measured by body mass index and blood pressure. [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
Height and weight is measured for the determination of body mass index (BMI). Waist circumference is measured using a non-stretchable standard tape measure. Systolic blood pressure is measured in a seated position after a five-minute rest period using an automated, non-invasive blood pressure monitor (BPTru) that automatically performs six measurements
Enrollment in Heart Wise Exercise programs [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
Enrollment in community-based and Heart Wise Exercise programs will be queried in the follow-up surveys.
Mediators of Intervention Effect [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
1.Physical activity history 2.Physical activity self-regulation 3. Action planning 4. Intentions to exercise 5. Beliefs about the benefits of and barriers to exercise 5. Task self-efficacy 6. Barrier self-efficacy 7. Social support from family and friends 8. Autonomy support derived from health care providers 9. Home exercise equipment 10. Neighbourhood environmental attributes of walkability and access to recreation facilities 11. Adherence to medications
Cost-effectiveness and cost-utility [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
Health effects are measured by overall survival time; event-free time from myocardial infarction, revascularization or death; and quality adjusted life years. Participants are linked to health administrative data to allow health care utilization to be tracked. Participants complete a monthly diary to record time for counseling and physical activities, out-of-pocket expenses, and items related to productivity, including lost work days, home care expenses due to reduced function or cardiac disability. Data is collected on the resources expended for each intervention.

Arms	Assigned Interventions
Experimental: Exercise Facilitator Intervention The intervention employs small group counseling teleconferences (5),personal telephone contacts (3) and community Heart Wise Exercise program demonstrations.	Behavioral: Exercise Facilitator Intervention The 50 week intervention includes 5 small group counseling teleconferences, 3 personal telephone calls and Heart Wise Exercise program demonstrations. During the teleconferences and personal telephone calls, the facilitator discusses the importance of exercise. Participants review their activity diaries, identify barriers to exercise maintenance experienced to date and brainstorm solutions as a group. In addition, the facilitator conducts community program demonstrations at Heart Wise Exercise program locations in Ottawa and Toronto for interested participants.
No Intervention: Usual Care Usual care for cardiac rehab graduates provided by the University of Ottawa Heart Institute Minto Prevention & Rehabilitation Centre and the Cardiovascular Rehabilitation and Prevention Centre at the University Health Network.

Criteria

Inclusion Criteria:
