Insights
A pharmacist-led home blood pressure monitoring (HBPM) intervention significantly improved blood pressure control and patient satisfaction compared to usual care. This approach offers a superior method for managing hypertension.
Area of Science:
- Cardiovascular Medicine
- Pharmacotherapy
- Health Services Research
Background:
- Hypertension management remains a critical public health challenge.
- Optimizing blood pressure (BP) control through innovative interventions is essential.
- Usual care (UC) often results in suboptimal BP control for many patients.
Purpose of the Study:
- To evaluate the efficacy of a pharmacist-led, Heart360-enabled home blood pressure monitoring (HBPM) intervention.
- To compare BP control in patients receiving the HBPM intervention versus UC.
- To assess patient satisfaction with the HBPM intervention.
Main Methods:
- A randomized, controlled trial involving 348 patients with elevated BP across 10 clinics.
- Patients were randomized to either the HBPM intervention group (n=175) or the UC group (n=173).
- BP control, medication adjustments, and patient satisfaction were assessed over a 6-month period.
Main Results:
- The HBPM group achieved a significantly higher proportion of patients at their BP goal (54.1% vs. 35.4%, P<0.001).
- The intervention resulted in significantly greater reductions in systolic BP (-12.4 mm Hg) and diastolic BP (-5.7 mm Hg) compared to UC.
- Patients in the HBPM group reported higher satisfaction with their hypertension care (58% vs. 42%, P<0.001).
Conclusions:
- Pharmacist-led HBPM, supported by Heart360 technology, effectively improves blood pressure control.
- The intervention demonstrates superior outcomes in BP reduction and patient satisfaction compared to usual care.
- This model shows promise for enhancing hypertension management, particularly in patient subgroups with diabetes or chronic kidney disease.
Background:
To determine whether a pharmacist-led, Heart360-enabled, home blood pressure monitoring (HBPM) intervention improves blood pressure (BP) control compared with usual care (UC).
Methods And Results:
This randomized, controlled trial was conducted in 10 Kaiser Permanente Colorado clinics. Overall, 348 patients with BP above recommended levels were randomized to the HBPM (n=175) or UC (n=173) groups. There were no statistically significant differences in baseline characteristics between the groups; however, there was a trend toward a higher baseline BP for the HBPM group compared with the UC group (148.8 versus 145.5 mm Hg for systolic BP; 89.6 versus 88.0 mm Hg for diastolic BP). At 6 months, the proportion of patients achieving BP goal was significantly higher in the HBPM group (54.1%) than in the UC group (35.4%; P<0.001). Compared with the UC group, the HBPM group experienced a -12.4-mm Hg larger (95% confidence interval, -16.3 to -8.6) reduction in systolic BP and a -5.7-mm Hg larger (95% confidence interval, -7.8 to -3.6) reduction in diastolic BP. The impact of the intervention on BP reduction was even larger for the subgroup of patients with diabetes mellitus or chronic kidney disease. The HBPM group had more e-mail and telephone contacts and greater medication regimen intensification. The proportion of patients reporting high satisfaction with hypertension care was significantly greater in the HBPM group (58%) than in the UC group (42%), P<0.001.
Conclusions:
A pharmacist-led, Heart360-supported, home BP monitoring intervention led to greater BP reductions, superior BP control, and higher patient satisfaction than UC.
