An Integrated Community-Based Blood Pressure Telemonitoring Program - A Population-Based Observational Study.

Background: Home blood pressure telemonitoring (BPT) has been shown to improve blood pressure control. A community-based BPT program (the + program) was launched in 2015 in an urban area around a medical center.

Objectives: To examine the impact of the BPT program on the use of medical resources.

Methods: We conducted a retrospective propensity-score (PS)-matched observational cohort study using the National Health Insurance Research Database (NHIRD) 2013-2016 in Taiwan. A total of 9,546 adults with a high risk of cardiovascular disease participated in the integrated BPT program, and 19,082 PS-matched controls were identified from the NHIRD. The primary and secondary outcome measures were changes in 1-year emergency department visit rate, hospitalization rate, duration of hospital stay, and healthcare costs.

Results: The number of emergency department visits in the + group significantly reduced (0.8 to 0.6 per year vs. 0.8 to 0.9 per year, p < 0.0001) along with a significant decrease in hospitalization rate (43.7% to 21.3% vs. 42.7% to 35.3%, p < 0.001). The duration of hospital stay was also lower in the + group (4.3 to 3.3 days vs. 5.3 to 6.5 days, p < 0.0001). The annual healthcare costs decreased more in the + group (USD 1642 to 1169 vs. 1466 to 1393 per year, p < 0.001), compared with the controls. Subgroup analysis of the + group revealed that the improvements in outcomes were significantly greater among those who were younger and had fewer comorbidities, especially without diabetes or hypertension.

Conclusions: A community-based integrated BPT program may improve patients' health outcomes and reduce healthcare costs.
