Abstract 56: Blood Pressure Control in the Real World - Early Evidence From a National Blood Pressure Surveillance System

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.
