Cost-effectiveness of implementing a home blood pressure telemonitoring program.

Area of Science:

• Health Services Research
• Cardiovascular Disease Management
• Health Economics

Background:

• Hypertension management is crucial for preventing cardiovascular events.
• Home blood pressure telemonitoring (HBPT) offers a potential solution for improving hypertension control.
• Evaluating the cost-effectiveness of HBPT programs is essential for widespread implementation.

Purpose of the Study:

• To assess the 12-month cost-effectiveness of implementing a home blood pressure telemonitoring (HBPT) program.
• To analyze the impact of HBPT on healthcare utilization and costs in a large US integrated health care system.

Main Methods:

• Retrospective cohort study analyzing data from 3067 patients in a Kaiser Permanente HBPT program.
• Estimated program implementation costs and hypertension-related healthcare costs 12 months pre- and post-enrollment.
• Used inverse probability of treatment weights and difference-in-differences analysis to compare outcomes.

Main Results:

• HBPT program implementation costs averaged $113.35 per patient.
• The program reduced office visit and BP clinic costs but increased virtual encounter costs.
• Achieved modest reductions in systolic BP (1.42 mm Hg) and diastolic BP (1.58 mm Hg).
• Incremental cost-effectiveness ratios were $81.67/mm Hg SBP reduction and $73.22/mm Hg DBP reduction.

Conclusions:

• The HBPT program demonstrated modest blood pressure reductions in a real-world setting.
• Overall healthcare costs increased, primarily driven by initial enrollment expenses.
• Further analysis is needed to optimize HBPT programs for improved cost-effectiveness.
