Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group will receive the self-management support Flinder Program for six months.
Flinders Program is a one-to-one self-management support program. It involves a 1-hour face-to-face session during which a trained nurse and the participant identify and prioritise the issues due to the chronic condition(s) the participant has. They then agree on a care plan based upon goals established for prioritised issues.
Adherence to the intervention is monitored by weekly/fortnightly (based on a mutual agreement) phone calls.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be chosen from the Repatriation Hospital knee or hip arthroplasty waiting list who have a BMI of 30 or above. They will be sent the patient information sheet, and will be contacted by phone a week after to arrange a visit time if interested. During the arranged visit time, the investigator will explain the purposes, methods, possible risks and benefits of participating in the study. A biostatistician will generate randomised sequences, and the clinical trial pharmacy at Repatriation Hospital will perform the allocation. Allocation involves contacting the holder of the allocation schedule -at the clinical trial pharmacy- who is off-site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be blocked using varying block sizes, and will be stratified for BMI groups (30-34.9, 35-39.9, 40 and above), and gender.

Efficacy
Statistical methods / analysis
Self-management support Flinders Program is a safe intervention, and little harm in the application of such a program is expected, therefore, the consequences of a type I error are not severe. Based on a type I error of 0.1, power of 80% and effect size of 0.6 and a two tailed test, the sample size is calculated to 72. With an anticipated drop out rate of 30%, the total sample size is calculated to be 94.
