BACKGROUND: The objective of this descriptive study is to investigate the incidence of type 2 diabetes in sentinel general practices in three regions in Belgium and to describe the patient characteristics and the start of the medical management after diagnosis. METHODS: For two successive years all patients who were newly diagnosed with type 2 diabetes were registered. Two weeks after inclusion, the registering physician completed an extensive questionnaire. This questionnaire dealt with risk factors, biochemical parameters, existing complications and treatment. RESULTS: According to this study, the yearly incidence of type 2 diabetes in Belgium is 231 per 100,000 inhabitants. Though the biochemical parameters (BMI, HbA1c, serum cholesterol and triglycerides) do not differ in the three regions of the country being investigated, there are considerable differences in the treatment prescribed for diabetes and its co-morbidity. In Flanders, treatment is usually started with sulphonylurea, in the Walloon provinces with biguanides. Hypolipaemic treatment is also started more frequently in the latter region. In Flanders, hypertension is registered in 51.4% of the newly diagnosed patients with diabetes, which is higher than in the other regions. However, no difference is noted between the different regions in the number of patients with diabetes who are treated for hypertension. CONCLUSION: A network of sentinel physicians, taking part in voluntary registration, can be helpful in calculating the incidence of a health problem, in particular type 2 diabetes in general practice. The sentinel net can also serve as an instrument for describing patient characteristics and showing how physicians deal with health problems. The regional differences in medical approach that are described require further investigation, mainly with respect to their impact on the patients' outcome.
