Insights
Remote blood pressure monitoring (RBPM) effectively lowers systolic and diastolic blood pressure in urban hypertensive patients. This method also improves blood pressure control rates, offering a valuable tool for managing hypertension.
Area of Science:
- Cardiology
- Public Health
- Health Informatics
Background:
- Hypertension management is crucial, especially post-pandemic.
- Remote blood pressure monitoring (RBPM) offers a novel approach for patient care.
- Urban populations with high healthcare access present a specific context for evaluating RBPM.
Purpose of the Study:
- To evaluate the overall effects of RBPM on urban hypertensive patients.
- To provide updated quantitative summary data on RBPM efficacy.
- To assess RBPM's impact on blood pressure control rates.
Main Methods:
- A meta-analysis of 32 high-quality studies (48 comparisons) was conducted.
- Data was synthesized from inception to November 2020, including 2721 initially searched articles.
- A random effects model was used to analyze changes in office systolic blood pressure (SBP) and diastolic blood pressure (DBP).
Main Results:
- RBPM significantly reduced SBP (SMD 0.507, WMD 4.464 mmHg) and DBP (SMD 0.315, WMD 2.075 mmHg) compared to usual care.
- The blood pressure control rate was higher in the RBPM group (RR 1.226).
- RBPM effectiveness was associated with city size, monitoring frequency, intervention duration, and absence of medically underserved areas.
Conclusions:
- RBPM is an effective strategy for reducing blood pressure in urban hypertensive patients.
- RBPM contributes to achieving target blood pressure levels.
- The findings support the integration of RBPM into routine hypertension management for urban populations.
Abstract:
Following the coronavirus disease-2019 pandemic, this study aimed to evaluate the overall effects of remote blood pressure monitoring (RBPM) for urban-dwelling patients with hypertension and high accessibility to healthcare and provide updated quantitative summary data. Of 2721 database-searched articles from RBPM's inception to November 2020, 32 high-quality studies (48 comparisons) were selected as primary data for synthesis. A meta-analysis was undertaken using a random effects model. Primary outcomes were changes in office systolic blood pressure (SBP) and diastolic blood pressure (DBP) following RBPM. The secondary outcome was the BP control rate. Compared with a usual care group, there was a decrease in SBP and DBP in the RBPM group (standardized mean difference 0.507 (95% confidence interval [CI] 0.339-0.675, p < 0.001; weighted mean difference [WMD] 4.464 mmHg, p < 0.001) and 0.315 (CI 0.209-0.422, p < 0.001; WMD 2.075 mmHg, p < 0.001), respectively). The RBPM group had a higher BP control rate based on a relative ratio (RR) of 1.226 (1.107-1.358, p < 0.001). RBPM effects increased with increases in city size and frequent monitoring, with decreases in intervention duration, and in cities without medically underserved areas. RBPM is effective in reducing BP and in achieving target BP levels for urban-dwelling patients with hypertension.

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.
