ELSID - Evaluation of a Large Scale Implementation of Disease Management Programmes for patients with type 2 diabetes

INTERVENTION: Randomisation between DMP 1 and DMP 2. GPs in the DMP 1 group will offer regular consultations at 3‐ or 6‐month intervals including detailed diabetes‐specific anamnesis, physical examination including taking blood pressure and analysis of HbA1c.
