Encouragement of patients' self-management in primary care for the prevention of cardiovascular diseases (DECADE): protocol for a cluster randomised controlled trial.

Introduction: Cardiovascular diseases are the most common cause of death in Germany and among the most frequent reasons for encounters in primary care. Most patients with cardiovascular risks (CVRs) have difficulties implementing health-promoting behavioural changes. In this study, a complex intervention containing evidence-based patient materials and structured follow-up consultations are intended to strengthen patients' self-management to improve health behaviour.
