DECADE-pilot: decision aid, action planning, and follow-up support for patients to reduce the 10-year risk of cardiovascular diseases-a protocol of a randomized controlled pilot trial.

BACKGROUND

A healthy lifestyle can reduce cardiovascular risk (CVR) and prevent premature death. Usually most patients at increased CVR have difficulties implementing the necessary health behavior changes, such as smoking cessation, increasing of physical activity, healthy diet, stress reduction, etc. In this pilot study, a new intervention (DECADE) that includes a cardiovascular risk calculation, evidence-based decision aids, action planning, and follow-up support for patients to reduce their 10-year risk of cardiovascular diseases will be tested in primary care. The objectives of this trial are to test (1) the feasibility of the study design in preparation for the main trail including (2) the usability and acceptance of DECADE, and (3) initial data to ascertain that changes can be observed in these patients.

METHODS

This randomized controlled pilot trial will generate initial data on the potential effects of DECADE on patients' self-evaluated activity and behavior change as well as on clinical outcomes such as blood pressure, cholesterol, body mass index (BMI), HbA1C, and CVR score. In the qualitative part of the study, we will analyze data collected in semi-structured interviews with participating general practitioners (GP) and in patient questionnaires.

DISCUSSION

The outcomes of this pilot study will indicate whether DECADE is a promising intervention in the domain of patient-centered prevention of cardiovascular diseases (CVD) and whether a larger multi-center randomized controlled trial is feasible.
