Plain English Summary
Background and study aims
Patient self-management and peer support are promising new approaches in diabetes care. This study will show whether peer support including occasional professional support can help people with type 2 diabetes improve their quality of life.
Who can participate?
A total of 77 GP surgeries and 1327 patients currently enrolled in the "Therapie aktiv" disease management programme in the province of Salzburg are invited to participate.
What does the study involve?
Participants will be randomly allocated into either the intervention group or the control group. Participants in the intervention group will take part in a peer support programme, which consists of regular group meetings of patients with type 2 diabetes run by trained peer supporters. They will exercise together, talk about medical, nutritional, personal, social and emotional issues regarding diabetes, and will receive occasional support from doctors, dieticians, diabetes nurses, clinical psychologists and physical education trainers. Those allocated to the control group will receive usual care within the disease management programme.
What are the possible benefits and risks of participating?
The possible benefits include higher quality of life, better control of blood pressure and weight loss.
Where is the study run from?
Paracelsus Medical University (Austria)
When is the study starting and how long is it expected to run for?
June 2010 to August 2013
Who is funding the study?
International Diabetes Federation (Belgium)
Who is the main contact?
Effectiveness of a peer support program versus care as usual in disease management regarding improvement of metabolic control and diabetes management self-efficacy: a cluster-randomised controlled trial
As an additional component of disease management the peer support program Di-AKTIV improves metabolic control, patient self-management efficacy, risk profile and quality of life of patients with diabetes mellitus type 2.

Diabetes mellitus type 2
1. Intervention group:
Peer support group meetings and exercise modules (1h per week). Patients will be encouraged to further daily exercising. The aim is to achieve at least an exercise level of 1000 kcal/week. A handbook regarding the following topics will be given to the peer groups:
1.1. daily management and living with diabetes
1.2. basic understanding of diabetes and diabetes care
1.3. diabetic medication
1.4. nutrition and diabetes
1.5. physical exercise, specifically motivational problems that may lead to less exercising than recommended
1.6. cardiovascular risk management
1.7. diabetic foot care and prevention
1.8. prevention of diabetic complications
Peer groups will get professional guidance by nutritionists, doctors, sports instructors and psychologists twice a year by each
2. Control group:
Usual care within the Disease Management Programme "Therapie aktiv"
Primary outcome measures
Current primary outcome measures as of 12/07/2013:
Decrease in HbA1c in the intervention group compared to controls, to be measured between 01/10/2010-31/07/2011 (baseline) and 01/10/2010-31/07/2013
Previous primary outcome measures:
Decrease in HbA1c in the intervention group compared to controls, to be measured between 01/10-31/12/2010 (baseline) and 01/10-31/12/2012 (end of intervention).
Secondary outcome measures
Current secondary outcome measures as of 12/07/2013:
1. Higher quality of life
2. Improved control of cardiovascular risk factors (hypertension, hyperlipidemia)
3. Lowering of global cardiovascular risk
4. Weight (body mass index [BMI]) reduction
5. Increased smoking cessation
The secondary outcomes will be measured between 01/10/2010-31/07/2011 (baseline) and 01/10/2010-31/07/2013 (end of intervention).
Previous secondary outcome measures:
