Background Uncontrolled blood pressure (BP) remains a leading cause of death in the United States. The American Medical Association developed a quality improvement program to improve BP control, but it is unclear how to efficiently implement this program at scale across multiple health systems. Methods and Results We conducted BP MAP (Blood Pressure Measure Accurately, Act Rapidly, and Partner With Patients), a comparative effectiveness trial with clinic‐level randomization to compare 2 scalable versions of the quality improvement program: Full Support (with support from quality improvement expert) and Self‐Guided (using only online materials). Outcomes were clinic‐level BP control (<140/90 mm Hg) and other BP‐related process metrics calculated using electronic health record data. Difference‐in‐differences were used to compare changes in outcomes from baseline to 6 months, between intervention arms, and to a nonrandomized Usual Care arm composed of 18 health systems. A total of 24 safety‐net clinics in 9 different health systems underwent randomization and then simultaneous implementation. BP control increased from 56.7% to 59.1% in the Full Support arm, and 62.0% to 63.1% in the Self‐Guided arm, whereas BP control dropped slightly from 61.3% to 60.9% in the Usual Care arm. The between‐group differences‐in‐differences were not statistically significant (Full Support versus Self‐Guided=+1.2% [95% CI, −3.2% to 5.6%], P =0.59; Full Support versus Usual Care=+3.2% [−0.5% to 6.9%], P =0.09; Self‐Guided versus Usual Care=+2.0% [−0.4% to 4.5%], P =0.10). Conclusions In this randomized trial, 2 methods of implementing a quality improvement intervention in 24 safety net clinics led to modest improvements in BP control that were not statistically significant.

Background: The Patient-Centered Outcomes Research Institute (PCORI) funded National Blood Pressure Surveillance System (BP Track) is a new national system that generates quarterly metrics of blood pressure (BP) control and BP-related quality metrics for participating healthcare systems from electronic health record (EHR) data. Methods: Queries against standardized EHR data in the national Patient-Centered Clinical Research Network (PCORnet) Common Data Model format produce a set of quality metrics relevant to improving BP control, including Controlling High BP (NQF 0018) and Improvement in BP (CMS65v7), and eight process measures specific to clinical management and treatment practices for improving BP control ( Table ). The metrics, aggregated overall and by health system are reported back to health systems via user-friendly Tableau dashboards, and allow for observation of metric trends. Results: To date, 19 datamarts have contributed EHR data from 1,177,232 patients who met the eligibility criteria for the BP Control measure and 4,454,729 encounters that included a BP measurement during the measurement period. Average age was 62 years; 10% were young adults (<45 years), 17% were African American, 52% female, 28% had diabetes, 15% had coronary heart disease, and 14% had depression. Results demonstrate substantial opportunity for improvement in overall BP control (60% with BP<140/<90 mmHg, range: 42-72%), and many healthcare processes, including medication intensification (12%, 0.6-22%) and use of fixed dose combination medications (24%, 0-88%, Table ). Conclusion: Major opportunities exist for improving BP control, especially in improving the frequency and quality of BP medication prescribing for patients with high BP. The BP Track National BP Surveillance System will track these metrics, by demographic subgroup and over time, and will generate data that can guide and focus quality improvement initiatives aimed at effective BP management.
