Table 2 Definitions of significant improvement per outcome measure

Adherence to medication and life style recommendations (Primary outcomes)

Using the distribution on the Morisky scale [14] of low, medium, and high adherence ratios, a post CHEP effect shift of 10% to a higher category will be defined as a significant improvement in adherence.

Blood pressure (Secondary outcome)

Blood pressure decrease of >10% systolic or diastolic or blood pressure at target level (patients without diabetes or established CVD: <140 mmHg systolic and <90 mmHg diastolic, patients with diabetes, renal disease or established CVD: <130 mm Hg systolic and <80 mmHg diastolic).

Body mass index (kg/m² )

No CVD risk: <25

Moderate CVD risk: 25-30

High CVD risk: >30

In patients with a BMI >25 any reduction of BMI at 6 months will be regarded as an improvement.
