Reducing Uncontrolled Hypertension Among Medicare Patients with Home Blood Pressure Monitoring and Timely Follow-up Based on a Quality Improvement Project

Objectives: Optimal hypertension (HTN) control is critical for reducing cardiovascular risk. National quality measures and clinical guidelines for HTN define the most recent BP reading of ≥140/90 mmHg during the performance year as uncontrolled. In the current study, we aim to improve and standardize HTN management and control through process improvement cycles in an Academic outpatient primary care setting. Methods: Using our outpatient database, we first identified a sample of Medicare beneficiaries with HTN determined to be uncontrolled during performance years 2023 and 2024, and performing root-case analyses to find any contributing factors, and develop a strategy for improving HTN control and quality metrics. Results: A lack of repeat BP measurement and inadequate follow-up were found to be the major factors contributing to uncontrolled BP. Home Blood Pressure Monitoring (HBPM) with timely follow-up was tested as a potential opportunity for improving HTN quality metrics in these patients. Device validation showed that 40 of 42 home BP monitors provided accurate readings. Subsequently, 38 BP uncontrolled patients were engaged through home or office BP assessments. After 2 weeks, 25 of 38 (66%) patients achieved Medicare-defined BP controlled, including 10 through HBPM alone, 8 with follow up during an office visit. Thirteen patients were still BP uncontrolled with a relative risk (RR) of 0.34 (95% CI: 0.22-0.52, P < .001). Conclusion: These results support HBPM together with close follow-up as an effective approach to reduce the risk of uncontrolled hypertension and associated noncompliance in value-based care reporting.
