Telemonitoring at scale for hypertension in primary care: An implementation study.

Area of Science:

• Digital health interventions
• Cardiovascular disease management
• Primary care innovation

Background:

• Randomized controlled trials indicate telemonitoring improves hypertension control.
• Healthcare systems face challenges integrating telemonitoring into existing practices and electronic records.
• Replication of trial findings in routine, large-scale clinical practice remains unclear.

Purpose of the Study:

• To explore the feasibility of implementing an integrated telemonitoring system for hypertension into routine primary care.
• To assess the impact of this integrated system on blood pressure control and clinical resource utilization.

Main Methods:

• A quasi-experimental implementation study with qualitative process evaluation in primary care.
• Utilized routinely acquired data for a before-and-after study (n=3,200 patients across 75 practices).
• Collected qualitative data through interviews and practice observations.

Main Results:

• Mean systolic blood pressure (BP) fell by 6.55 mm Hg and diastolic BP by 4.23 mm Hg in the telemonitoring subgroup (n=905).
• Participating patients had 19% fewer face-to-face appointments compared to non-telemonitored patients.
• Convenient remote BP monitoring and integration into clinical care were key facilitators.

Conclusions:

• Telemonitoring for hypertension can be successfully implemented at scale in routine primary care.
• The system showed minimal impact on clinician workload and achieved BP reductions comparable to large trials.
• Seamless integration of telemonitoring data into routine clinical workflows is critical for success.
