|Data Element Information|
|Rationale for Separate Consideration||USCDI has Diastolic Blood Pressure and Systolic Blood Pressure, but it does not have average (computed) blood pressures for each.|
|Use Case Description(s)|
|Use Case Description||Over 85 million adults in the United States have high blood pressure. Average blood pressure readings can guide the diagnosis and treatment of hypertension.
The M.A.P. (Measure Accurately, Act Rapidly and Partner with Patients) BP Improvement Program is an integral part of Target: BPTM, a national initiative formed by the American Heart Association and the American Medical Association in response to the rising incidence of uncontrolled BP. Guidance in the M.A.P. Program includes:
• For those with an initial screening blood pressure reading above the cut-off threshold, the average of two or more BP readings is recommended.
• For those doing self-measured blood pressure (SMBP) monitoring the M.A.P. Program also provides a protocol for measuring an average blood pressure over the course of a week.
|Estimated number of stakeholders capturing, accessing using or exchanging||Over 85 million adults in the United States have high blood pressure. Average BP measurements can be used by thousands of physicians to better diagnose and manage hypertension.|

|Maturity of Use and Technical Specifications for Data Element|
|Applicable Standard(s)||SNOMED CT has:
723232008 |Average blood pressure (observable entity)|
314453003 |Average diastolic blood pressure (observable entity)|
314440001 |Average systolic blood pressure (observable entity)|
LOINC - Does not yet include this data element.
|Additional Specifications||The data element is included in the HL7 FHIR® Implementation Guide: Vital Signs, Release 1- US Realm (1st Standard for Trial Use Ballot) which went through the ballot cycle in September 2020.|
|Current Use||In limited use in production environments|
Cerner, Epic and Higi use Average Blood Pressures (systolic and diastolic).
Submission of this data element is also rooted in the information cited in:
2017 ACC/AHA/AAPA/ABC/ACPM/AGS/APhA/ASH/ASPC/NMA/PCNA Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults: Executive Summary: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines
For example, the cited document states, “BP is categorized into 4 levels on the basis of average BP measured in a healthcare setting (office pressures): normal, elevated, and stage 1 or 2 hypertension.”
|Number of organizations/individuals with which this data element has been electronically exchanged||2-3|
To our knowledge, there are production implementations that exchange Average Blood Pressure information using FHIR. Specifically, we are aware that at least Higi and Cerner exchange this data through a SMART Application.
|Restrictions on Standardization (e.g. proprietary code)||N/A|
|Restrictions on Use (e.g. licensing, user fees)||N/A|
|Privacy and Security Concerns||We support expanding the USCDI and the overall goal of getting meaningful information into the hands of clinicians and patients. However, we stress that the USCDI coupled with increased access to this information (both inside and outside HIPAA), could create a conduit for bad actors to syphon sensitive data from patients. We believe there should always be a balance between more information and strengthening patients’ trust in how the information is used.
As with any personal information, there is a need to ensure patients are comfortable sharing such data with their physicians. Thus, we encourage ONC to expand the USCDI to include average blood pressure data elements while concurrently coordinating with standards development organizations working to ensure data is shared with appropriate protections, including when it is accessed by third parties outside of the health care system.
|Estimate of Overall Burden||Unknown|
Physiologic measurements of a patient that indicate the status of the body’s life sustaining functions.
Information from the submission form
Average Blood Pressure
Average Blood Pressure represents the average of two or more blood pressure readings in a specified time period or according to a specified algorithm or protocol. (Of note, average blood pressure is not the same as a mean arterial pressure.) The average blood pressure has a systolic and a diastolic component.
