Background: Guidelines for type 2 diabetes care in general practice are well known and accepted, but the implementation falls short.
Objective: To implement these guidelines by introducing a diabetes support service (DSS) to support the care delivered by the GP.
Methods: A controlled, non-randomised study with delayed intervention in the control group; 78 GPs (n=51 for the intervention and n=21 for the control group) in the south of the Netherlands and 613 of their type 2 diabetic patients participated.
