2. Aim To evaluate, by means of a pragmatic cluster randomized controlled trial, the effectiveness of a group diabetes education programme delivered by trained health promoters with a guiding (derived from motivational interviewing) style, in community health centres in Cape Town, South Africa.

3. Method 17 community health centres in each arm 710 patients with type 2 diabetes in intervention 860 patients with type 2 diabetes in control Data collection at baseline and 12-months Primary outcomes: Improved diabetes self-care activities, 5% weight loss, HbA1c reduction of 1 percentage point Secondary outcomes: Improved diabetes-specific self-efficacy, locus of control, mean blood pressure, mean weight loss, mean waist circumference, mean HbA1c, mean total cholesterol and quality of life Mash B, Levitt N, Steyn K, Zwarenstein M, Rollnick S.

5. Structure 4 sessions: ◦ Understanding diabetes ◦ Lifestyle modification ◦ Understanding medication ◦ Avoiding complications 60 minutes On day of usual attendance - monthly 10-15 people

6. Communication Guiding style Collaboration Empathy Independence Evocation Navigation Skills Exchange information (elicit- provide-elicit) Open questions Summaries and active listening

7. Resources

8. Training of health promoters

9. Process evaluation Patients that attended reported change in self-care activities Structure and resources were relevant, understandable, useful Health promoters perceived as mostly competent and confident Health promoters reported a significant shift in their way of communicating that was appreciated by patients Serfontein F, Mash B.

10. Process evaluation Direct observation and analysis of sessions showed good delivery of content, but partial fidelity to the guiding style Suitable space was a problem Patient attendance was a problem (40% only) Communication with patients sometimes a problem Botes AS, Majikela- Dlangamandla B, Mash R.

11. Results: 12 months

12. Conclusion Effect not as impressive as in other studies (see Cochrane review on group diabetes education) Effect on blood pressure clinically significant and useful Likely to be cost-effective Consider integration into chronic care system for NCDs with other diseases Department of health has requested training of all other health promoters
