Implementation of locally adapted guidelines on type 2 diabetes.
OBJECTIVE
To assess the effects of a facilitator enhanced multifaceted intervention to implement a locally adapted guideline on the shared care for people with type 2 diabetes.


METHODS
During 1 year a cluster-randomized trial was performed in 30 general practices. In the intervention group, nurse facilitators enhanced guideline implementation by analysing barriers to change, introducing structured care, training practice staff and giving performance feedback. Targets for HbA1c%, systolic blood pressure as well as indications for angiotensin converting enzyme/angiotensin receptor blocking agent prescription differed from the national guidelines. In the control group, GPs were asked to continue the care for people with diabetes as usually. Generalized estimating equations were used to control for the clustered design of the study.


RESULTS
In the intervention group, more people were seen on a 3-monthly basis (88% versus 69%, P < 0.001) and more blood pressure and bodyweight measurements were performed every 3 months (blood pressure 83% versus 66%, P < 0.001 and bodyweight 78.9% versus 48.5%, P < 0.001). Apart from a marginal difference in mean cholesterol, differences in HbA1c%, blood pressure, body mass index and treatment satisfaction were not significant.


CONCLUSIONS
Multifaceted implementation of locally adapted shared care guidelines did improve the process of diabetes care but hardly changed intermediate outcomes. In the short term, local adaptation of shared care guidelines does not improve the cardiovascular risks of people with type 2 diabetes.
