Self-measured blood pressure monitoring with support effectively controls blood pressure. Simple technologies like phone systems and websites, with as-needed provider interaction, offer the best cost-effectiveness for this intervention.
Area of Science:
- Health Economics
- Cardiovascular Health
- Health Services Research
Background:
- Self-measured blood pressure monitoring with support is a proven method for managing hypertension.
- Understanding the economic aspects of these interventions is crucial for widespread implementation.
Purpose of the Study:
- To systematically review the effectiveness and cost-effectiveness of self-measured blood pressure monitoring with support.
- To identify intervention characteristics that influence cost and effectiveness.
Main Methods:
- A systematic economic review of 22 studies published up to March 2021.
- Inclusion criteria focused on blood pressure change and intervention cost, excluding specific conditions.
- Analysis of patient characteristics and intervention features impacting outcomes.
Main Results:
- No significant difference in cost or cost-effectiveness based on the type of support.
- Lower costs and better cost-effectiveness were associated with simple technologies (phone, smartphone, web).
- Interventions with only as-needed provider interaction were more cost-effective.
Conclusions:
- Simple technological support and minimal provider contact optimize the cost-effectiveness of self-measured blood pressure monitoring.
- This review provides valuable insights for both research and practical implementation of blood pressure management strategies.

Special considerations while measuring blood pressure
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.
