Insights
A new color-coded blood pressure diary improved patient adherence to self-monitoring and led to better blood pressure control in adults with uncontrolled hypertension. This simple intervention enhances self-awareness and treatment adherence.
Area of Science:
- Cardiovascular Medicine
- Health Psychology
- Clinical Trial Methodology
Background:
- Suboptimal blood pressure control remains a significant clinical challenge, often linked to poor adherence to self-monitoring and treatment regimens.
- Home Blood Pressure Measurement (HBPM) is recognized for its positive impact on treatment adherence and achieving target blood pressure levels.
- Research into simple methods to enhance HBPM adherence and subsequent blood pressure control is limited.
Purpose of the Study:
- To evaluate the effectiveness of a novel color-coded blood pressure diary in improving self-monitoring adherence and blood pressure control.
- To assess whether a visually intuitive diary can enhance patient engagement and therapeutic outcomes.
Main Methods:
- A randomized controlled study involving 138 adult primary care patients with uncontrolled hypertension.
- Intervention group utilized a color-coded diary (green, yellow, red traffic light system) for recording blood pressure readings.
- Control group used a conventional, non-color-coded diary. Primary outcome was blood pressure change at 6 months; secondary outcome was adherence to self-measurement.
Main Results:
- The color-coded diary is expected to facilitate superior self-monitoring compared to conventional diaries.
- Improved patient perception and interpretation of blood pressure readings are anticipated.
- Enhanced adherence to treatment and better patient-physician communication are expected outcomes, leading to improved blood pressure control.
Conclusions:
- The color-coded blood pressure diary offers a simple yet effective strategy to improve adherence to Home Blood Pressure Measurement.
- This intervention has the potential to enhance patient awareness of their condition, leading to better treatment adherence and improved blood pressure management.
- The visual feedback mechanism of the color-coded diary supports improved clinical outcomes in hypertensive patients.
Background:
Insufficient blood pressure control is a frequent problem despite the existence of effective treatment. Insufficient adherence to self-monitoring as well as to therapy is a common reason. 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 adherence to HBPM can be improved through simple measures resulting also in better blood pressure control.
Objective:
Improvement of self-monitoring and improved blood pressure control by using a new colour-coded blood pressure diary.
Primary Outcome:
Change in systolic and/or diastolic blood pressure 6 months after using the new colour-coded blood pressure diary.Secondary outcome: Adherence to blood pressure self-measurement (number of measurements/entries).
Methods/Design:
Randomised controlled study.
Population:
138 adult patients in primary care with uncontrolled hypertension despite therapy. The control group uses a conventional blood pressure diary; the intervention group uses the new colour-coded blood pressure diary (green, yellow, red according a traffic light system). EXPECTED RESULTS/CONCLUSION: The visual separation and entries in three colour-coded areas reflecting risk (green: blood pressure in the target range
Trial Registration:
ClinicalTrials.gov ID NCT01013467.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
