In the United States, 116 million adults (45%) have hypertension, a major risk factor for heart disease, kidney disease and stroke. This “silent killer” contributes to the death of nearly 500,000 Americans annually. Population-based analyses suggest that hypertension control is achieved in only 25%-30% of adults. Meta-analyses indicate that 45% of patients don’t adhere to their prescribed medications, and 25% do not fill their prescriptions. 

In 2022, the CARdiovascular Data eXchange (CardX) domain of CodeX was launched by the University of Nebraska Medical Center–Center for Intelligent Heath Care. The first CardX use case focuses on hypertension. Several objectives frame the use case: 1.) Facilitate a shift in the care paradigm from a focus on BP measured in the office to patient-enabled, self-measured BP; 2) Drive interoperable data exchange between patient and clinician through FHIR profiles specific to hypertension management data; 3.) Improve communication between patients and clinicians.

This presentation will describe the CodeX FHIR Accelerator, the CardX domain of Codex and the CardX hypertension use case in the context of aligning with the HEDIS CBP measure. The potential for data liquidity enabled by a “capture once, use for many purposes” framework should increase the proportion of patients treated to goal, improve clinical outcomes, reduce clinician burden and enable more complete and accurate reporting.
