CoCo: Colour Coded Blood Pressure Control

Insufficient blood pressure control is a frequent problem despite the existence of effective treatment. One of the causes is insufficient self-monitoring and a lack of adherence to therapy. Blood pressure self-measurement at home (Home Blood Pressure Measurement, HBPM) has positive effects on treatment adherence and is helpful in achieving the target blood pressure.

Only a few studies have investigated whether the adherence for HBPM can be improved through simple measures and better blood pressure monitoring can be achieved.

Inclusion criteria

Age >18 years

Unchanged anti-hypertension treatment for one month before inclusion
Patient able to measure blood pressure at home

Treatment and study plan

"CoCo" colour coded blood pressure control

Behavioral

The patients in the intervention group will receive a colour-coded blood pressure record booklet. The corresponding colour coded areas are divided into three areas of green, yellow and red following a traffic light system. The green area covers blood pressure readings up to a maximum of 140/90 mmHg, the yellow area includes systolic readings over 140 to 180 mm Hg and diastolic readings over 90 to 110 mmHg. The red area covers systolic readings over 180 mmHg and diastolic readings over 110 mmHg.

Primary outcomes

Primary outcome: change in systolic and/or diastolic blood pressure 6 months after using the new colour-coded blood pressure diary.

Time frame: 6months

Secondary outcomes

adherence with home blood pressure measurements

Time frame: 6 months
