Type 2 Diabetes Mellitus: New Approaches to Optimize Medical Care in General Practice (DIANA)

December 10, 2013 updated by: German Cancer Research Center

DIANA - Diabetes Mellitus: Neue Wege Der Optimierung Der allgemeinärztlichen Betreuung

Patients with type-2 diabetes mellitus have an higher risk developing secondary disorders. In an epidemiological longitudinal study of about 1.150 patients with type 2 diabetes mellitus we investigate determinants and predictors for long-term prognosis. The patients are recruited and supervised in practices of general practitioners of the administrative district of Ludwigsburg/Heilbronn (Baden-Württemberg, Germany). In a subgroup of about 200 patients with a dissatisfactory metabolic status (HbA1c > 7,5%) a randomised interventional study is performed. The intervention comprises a telephone counseling by the medical secretary of each practice executed in a predefined period of time. The outcome parameters of interest are the change of HbA1c, the development of secondary disorders and adverse events, quality of life and risk factor control, as well as hospitalization and mortality.

The aim of the study was to develop an patient-centred instrument implementable in the routine medical care in order to enhance the prognosis of patients with type-2 diabetes mellitus.
