Home Blood Pressure Monitoring and Its Association With Blood Pressure Control Among Hypertensive Patients With High...

Area of Science:

• Cardiology
• Hypertension Management
• Public Health

Background:

• Home blood pressure monitoring (HBPM) is widely used for hypertension management.
• Real-world effectiveness data on HBPM is limited.
• This study investigates HBPM's impact on blood pressure control and medication adherence.

Purpose of the Study:

• To examine the association between HBPM frequency and blood pressure control.
• To assess the relationship between HBPM frequency and medication adherence.
• To explore these associations stratified by patient perception of anti-hypertensive treatment.

Main Methods:

• Prospective cohort study of 5,363 hypertensive patients aged ≥50 years.
• Data collected on HBPM use, treatment perception, office BP, and medication adherence over 1 year.
• Log-binomial regression used to analyze associations between HBPM frequency and outcomes.

Main Results:

• No significant association found between HBPM frequency and baseline blood pressure control.
• Among patients with incorrect treatment perception, daily HBPM correlated with higher medication non-adherence.
• Daily HBPM was associated with increased non-adherence compared to less frequent monitoring (aRR=1.38, P=0.004).

Conclusions:

• HBPM use alone did not improve hypertension control in this Chinese cohort.
• Patient misconceptions about hypertension treatment negatively impact HBPM's effectiveness on adherence.
• Integrating accurate treatment understanding is crucial for optimizing HBPM in patient management.
