Remote home blood pressure monitoring (HBPM) has been shown as effective in managing
hypertension in underserved areas. Effects on urban patients, who are more easily provided
with high-quality medical services, are still unclear. We systematically review previously
published randomized controlled trials on the effect of HBPM for urban hypertensive patients.
We searched electronic databases for studies published in English up to October 2018. Studies
comparing the use of HBPM to face-to-face care were included. Outcome measures were
changes in office blood pressure (BP) and the rate of BP control.
We identified 1,433 potential references for screening, of which 27 were eligible for review.
Substantial heterogeneity was evident for the investigated variables. A significant standardized
mean difference (SMD) was observed for HBPM for SBP, but the effect size was small
compared to face-to-face care and was clinically irrelevant in avoiding cardiovascular events
(0.212: 95% confidence interval, 0.148 to 0.275; P < 0.001). For diastolic BP, the SMD between
the two groups was small (0.170, P < 0.001) and the effect of HBPM was irrelevant in
preventing cardiovascular events. The effect on the rate of BP control was significantly high
for the intervention group (relative risk: 1.136; P = 0.018).
This review demonstrates that HBPM performed on urban hypertensive patients has limited
value and seems not to be superior to ordinary care in avoidance of cardiovascular events.
Further studies are needed to provide more reliable information about the effectiveness of
HBPM in preventing hypertensive cardiovascular complications.
