Description of intervention(s) / exposure
A pilot study is proposed with 20 participants, using a prepost design, to determine the format required for a risk
factor management program. Participants will receive a patient-centred intervention targeting individualised risk factor management of 3 months duration with 3 month followup, including a community-based physical activity program, in addition to standard medical care. The program is based on health coaching principles.

The patient-centred intervention targeting individualised risk factor management involves a 1 hour face-to-face goal setting meeting at baseline. Ongoing support is provided throughout the trial by regular telephone calls from the intervention nurse. Patients will receive a mean of 4 calls (for about 10-20 minutes each) throughout the 3 month intervention period, depending on need. Motivational interviewing techniques will be used. Motivational interviewing, as described by Miller and Rollnick, is a method that works on facilitating and engaging intrinsic motivation within the client in order to change behaviour. The approach is non-judgmental, non-confrontational and non-adversarial.

The community-based physical activity program depends on what is available in a participant's local community, e.g. could be a walking group. The number of sessions involved will depend on the goals set by each individual participant, e.g. they may select to walk for 20 minutes 5 times per week.

Standard medical care involves a consultations with a GP, cardiologist or consultant. This is not determined by the study, and participants will continue to be treated by their doctors.

Strategies used to improve adherence to the intervention protocols include the validated Morisky self-report; community pharmacy dispensed history print-out; and INR time in therapeutic range.

Outcomes
Primary outcome [1] 289729 0
Change in body mass, assessed by weighing participants on bathroom scales.
Timepoint [1] 289729 0
Three months after a participant's baseline assessment.
Secondary outcome [1] 303115 0
Measures of other cardiovascular risk factors, including physical activity, heart rate and rhythm, smoking status, blood pressure, diet / alcohol, diabetic control and lipid profile.

Physical activity will be measured using the Global Physical Activity Questionnaire (GPAQ); heart rate and rhythm will be measured using a 12 lead electrocardiograph (ECG) and radial pulse; smoking status will be assessed using a carbon monoxide meter (smokerlyser); blood pressure will be measured with a supported right arm, participant seated using a calibrated digital sphygmomanometer and appropriate sized cuff; diabetic control will be assessed using fasting glucose and HbA1c measured by fasting blood sample; lipid profile will be assessed by total cholesterol, high density lipoprotein, low density lipoprotein and triglycerides measured by fasting blood sample.
Timepoint [1] 303115 0
Three months after each participant's baseline assessment.
Secondary outcome [2] 303116 0
Participants' psychosocial wellbeing.
This will be measured with the following validated tools: the Hospital Anxiety and Depression Scale (HADS), the SF-12 health survey and AFEQT questionnaire.
Timepoint [2] 303116 0
Three months after each patient's baseline assessment.
Secondary outcome [3] 303117 0
Unplanned hospital readmission for a cardiovascular reason or event. This will be assessed by monitoring hospital admission records.
Timepoint [3] 303117 0
For the 3 month duration of the pilot study.
Secondary outcome [4] 303257 0
Patients' adherence to medication. This will be assessed using the validated Morisky self-report tool; community pharmacy dispensed history print-out; and INR time in therapeutic range.
Timepoint [4] 303257 0
Three months after each patient's baseline assessment.

Purpose of the study
Prevention
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients meeting the inclusion and exclusion criteria will be approached by the hospital cardiac rehabilitation (CR) co-ordinator or CHOICE-AF research assistant, during their inpatient stay where-ever possible, or via letter or telephone soon after hospital discharge. The participant’s cardiologist will be approached prior to initial interview to ensure appropriateness for inclusion in the study.
No allocation concealment procedures are required for this study.

Efficacy
Statistical methods / analysis
Primary analyses will be conducted by intention-to-treat using SPSS for Windows (Version 17.0) and will be presented as mean and standard error of the mean or proportions. Differences in outcome measures, between and within groups, will be compared using repeated measures ANOVAs for continuous variables and either chi-square tests or Fishers exact tests, as appropriate, for proportions of categorical variables. Two tailed p values of less than 0.05 will be considered significant.
