About

This is a pre-and-post study with a study duration of one year involving 7 diabetes centres in Hong Kong. A group of motivated patients with type 2 diabetes will be trained as peer supporters in two training workshops. Patients who may benefit from peer support program will be recruited as peers. In the one year study period, peer supporters are required to have 2 face-to-face interviews and 12 phone calls. Clinical parameters and psycho-behavioral parameters of both peer supporters and peers will be evaluated at the baseline and at the end of the study.

Full description

Aim of the Study:

1. To evaluate the impact of peer support program on various clinical, psycho-behavioral outcomes and health utilization outcomes in Hong Kong Chinese with type 2 diabetes
2. To evaluate the feasibility of a peer support program in Hong Kong
3. To evaluate the sustainability of a peer support program in Hong Kong

Duration of the program = 12 months

Indicators and targets:

• Number of peer supporters recruited: 12
• Number of peers recruited = 50
• Number of peer supporter training sessions = 2
• Number of reunion sessions for peer supporters with the investigators = 4
• Minimum number of telephone calls made by peer supporter = 12 for each peer

Method:

1. The diabetes nurses from 7 diabetes centres of public hospitals in Hong Kong will recruit peer supporters and peers in the first 3 months of the project.

2. Nurses will compile list of potential patients to invite to become peer supporters.

3. Selected potential peer supporters will attend 2 half-day training sessions by the diabetes nurses and social workers from the Community Rehabilitation Network according to specially-designed curriculum. In sum, it includes revision of diabetes knowledge, self-management, lifestyle modification, debriefing and rapport building skills. Patients will be evaluated at the end of the training course by social workers and nurses to ensure they are ready to be peer supporters.

4. Diabetes nurses will recruit patients as peers when they attend to the diabetes centre for routine diabetes care services such as complication screening, diabetes group education and nurse-led clinics.

5. Each peer supporter will be matched to 5 peers in the beginning. In case when the peer supporter quitted before the study ends, his/her peers will be directed to another peer support group. The maximum number of peers in each support group is 6.

6. A 2-hour face-to-face introduction of the peer supporters and peers will be held at the diabetes centre when the study begins.

7. Peer supporters will be expected to carry out a minimum of12 phone calls over the next 12 months (one call every 2 weeks for 3 months; one call every month for the second 3 months, one call every 2 months for the last 6 months). Calls will be guided by a call checklist. Both peer supporters and peers will be encouraged to call one another ad lib. Peer supporters will return checklists to the program coordinator, recording the frequency, length, and nature of their interactions with peers

   In the first month of the peer support group, social workers from the Community Rehabilitation Network will contact peer leaders by phone to further foster the peer leader to be committed to the program and to increase their confidence in supporting their peers.

   Two large gatherings for all participants will be organized by the investigators at around 4-8 months after the study and near to the study completion.

8. All peer supporters and peers will receive usual medical follow-up at their original clinics.

9. Peer supporters will have reunion workshop at the diabetes centre with the nursing team and social worker every 2 months throughout the intervention. The workshop will last around 1 hour and it will address any issues the peer supporters encounter, provide some educational by a medical professional, and will facilitate sharing amongst peer supporters to develop a peer supporter network.

10. Surveys for peer supporters and involved staff will also be collected during the debriefing sessions to identify difficulties peer supporters are facing and to better inform ongoing training and education. Surveys will also be administered to peers at the end of the study to obtain opinions and suggestions about their peer support experience.

11. The intervention duration will be 12 months. However peers are encouraged to keep regular contact with peer leaders even after the intervention period ends.

12. A focus-group interview will be conducted by a trained psychologist to two of the peer groups to evaluate participants' satisfaction

Progress tracking:

Clinical, behavioral, and psychological data will be collected at baseline and at the end of the study (12 months):

1. Clinical measures to be done in introduction session and in the second large group gathering: Blood pressure Adiposity (body weight, waist circumference and body mass index)
2. Biochemical measures (HbA1c and lipid profile) were retrieved via the hospital Central Computer System within 2 months of the study starting date and the end date
3. Psychological measures, using validated self-administered questionnaires, to be completed in introduction session and in the second large group gathering:

World Health Organization quality of life questionnaire (WHO-QoL-26) for quality of life 15-item Chinese Diabetes Distress Scale (CDDS-15) for diabetes distress 8-item Patient Health Questionnaire for depressive symptoms EQ5D for quality of life Summary of Diabetes Self Care Activities (SDSCA) for adherence to diabetes self-care
