Key result
Hypertension telemonitoring is linked to ~16 minutes less consultation time per patient versus usual care.
Why the study?
Although RCTs demonstrate hypertension telemonitoring improves BP control, implementation has been slow due to inadequate integration with clinical practices, and it remains unclear whether trial findings replicate in routine practice at scale.
Does an integrated telemonitoring system for hypertension improve blood pressure control and reduce clinician workload in routine primary care?
Observational (n=3,200)
Yes
Does an integrated telemonitoring system for hypertension improve blood pressure control and reduce clinician workload in routine primary care?
Effect estimate: Adjusted mean difference 16.1 minutes (95% CI 0.1-32.1)
Absolute Event Rate: -15.4% vs -5.5%
p-value: p=0.048
Implementing an integrated telemonitoring system for hypertension in primary care is feasible at scale, reduces face-to-face appointments, and achieves clinically meaningful blood pressure reductions comparable to clinical trials.

Supports reduced primary care workload for hypertension; leaves open generalizability and BP effects beyond this cohort.
Hammersley et al. (2020) conducted an observational in Hypertension (n=3,200). Telemonitoring system for blood pressure (Scale-Up BP) vs. Usual care (non-telemonitored patients) was evaluated on Change in total consultation time (Adjusted mean difference 16.1 minutes, 95% CI 0.1-32.1, p=0.048). Telemonitoring for hypertension implemented at scale in primary care significantly reduced total consultation time by an adjusted mean of 16.1 minutes per patient compared to usual care.
