    Abstract

    Objective: The Diabetes Care Protocol combines task delegation (practice nurse), computerized decision support, and three-monthly feedback. We studied the effect of the Diabetes Care Protocol on HbA1c and cardiovascular risk factors in type 2 diabetes patients in primary care.

    Research Design and Methods: In a cluster randomized trial, mean changes in cardiovascular risk factors between intervention and control group after one year were calculated by generalized linear models.

    Results: Throughout the Netherlands 26 intervention practices included 1699 patients and 29 control practices 1692 patients. The difference in HbA1c change was not significant, total cholesterol, LDL-cholesterol, and blood pressure improved significantly more in the intervention group. The 10 year UKPDS coronary heart disease risk estimate improved 1.4% more in the intervention group.

    Conclusions: Delegation of routine diabetes care to a practice nurse combined with computerized decision support and feedback did not improve HbA1c, but reduced cardiovascular risk in type 2 diabetes patients.
