We assessed the effect of a multifaceted intervention directed at general practitioners to improve type 2 diabetes care.Three hundred and eleven Danish practices with 474 general practitioners were randomised to structured personal care (intervention group) or routine care (comparison group). Of 970 surviving patients (aged 40+ years) diagnosed with diabetes in 1989-1991, 874 (90.1%) were assessed after 6 years. Intervention comprised regular follow-up and individualized goal-setting, supported by reminders to doctors, clinical guidelines, feed-back, and continuing medical education.Predefined non-fatal outcomes and mortality were the same in both groups. The following risk factor levels were lower in the intervention patients than in the comparison patients: fasting plasma glucose (7.9 vs 8.7 mmol/l, medians, P = 0.0007), haemoglobin A1c (8.5 vs 9.0%, P0.0001, normal range 5.4-7.4%), systolic blood pressure (145 vs 150 mmHg, P = 0.0004), and cholesterols (6.0 vs 6.1 mmol/l, P = 0.029, baseline-adjusted). Both groups had sustained a weight loss since diagnosis (2.6 vs 2.0 kg). Metformin was the only drug used more frequently in the intervention group (24 vs 15%). Intervention doctors arranged more follow-up consultations, referred fewer patients to diabetes clinics, and were more optimistic in their goal-setting.In primary care, individualized goal-setting with educational and surveillance support may for at least six years bring risk factors of patients with type 2 diabetes to a level that in other trials has been shown to reduce diabetic complications, but without adverse weight gain. |
