Four-year long-term follow-up of diabetes patients after implementation of the Chronic Care Model in primary care: a cross-sectional study.

Aims: Implementing the Chronic Care Model (CCM) via involvement of specially trained practice nurses improves cardiovascular risk profiles and perception of care among type 2 diabetes patients in small primary care practices (PCPs) in the short term. Little is known about the long-term effects of this intervention.

Methods: Cross-sectional survey among the participants of the cluster randomised controlled CARAT trial (30 PCPs, 303 diabetes patients), 3 years after its completion.
