[Pilot study of controlled retrospective analysis (retrolective study design) of care for type 2 diabetics since 1990].

Background And Objective: There are few data on the quality of care received by patients with type 2 diabetes under routine conditions and only a few long-term studies that investigated the influence of treatment strategies on the development of clinical endpoints. It was the aim of this study, using retrospectively obtained data, to determine whether it is possible to document over a 10 year period the treatment design and clinical end-points in type 2 diabetics under the care of general practitioners.

Patients And Methods: General practitioners were randomly selected and informed by independent collaborating monitors about the aim of the study and data documentation.
