title: Routine diagnosis of Type 2 diabetes mellitus in general practice and hospitals: how do patients differ?
abstract: OBJECTIVE
  To study how Type 2 diabetic patients diagnosed by routine case-finding in primary care differ from patients diagnosed in secondary care with regard to clinical characteristics, symptom-burden and prevalence of complications.
  
  
  METHODS
  A Danish population-based sample of 1633 newly diagnosed Type 2 diabetic patients, of whom we had detailed information of sociodemographic and clinical characteristics, biochemical measurements, and complications among 1381. Blood and urine analyses were centralized.
  
  
  RESULTS
  Of the patients, 76.8% were diagnosed in general practice. Compared with those diagnosed in secondary care, patients diagnosed in general practice on average had higher levels of cardiovascular risk factors (BMI: 29.8 vs. 28.5 kg/m2, P < 0.001; systolic blood pressure: 149.4 vs. 143.2 mmHg, P < 0.001; diastolic blood pressure: 85.2 vs. 82.5 mmHg, P < 0.001; haemoglobin A(1c): 10.1 vs. 8.4%, P < 0.0001; total cholesterol: 6.4 vs. 6.1 mmol/l, P < 0.01), more frequently presented with hyperglycaemic symptoms (80.1 vs. 63.4%, P < 0.0001), while fewer had macrovascular complications (28.5 vs. 43.6%, P < 0.0001).
  
  
  CONCLUSIONS
  Judged from their risk profile, Type 2 diabetic patients diagnosed in primary care are at no less risk of developing diabetic complications than those diagnosed in secondary care.
