US Core Blood Pressure Profile inherits from the US Core Vital Signs Profile. This profile sets minimum expectations for the Observation resource to record, search, and fetch diastolic and systolic blood pressure observations with standard LOINC codes and UCUM units of measure. It specifies which additional core elements, extensions, vocabularies, and value sets SHALL be present in the resource and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption.

Example Usage Scenarios:

The following are example usage scenarios for this profile:

  • Query for blood pressure observations belonging to a patient
  • Record or update blood pressure observations belonging to a patient

Mandatory and Must Support Data Elements

In addition to the Mandatory and Must Support data elements in the US Core Vital Signs Profile, the following data elements must always be present (Mandatory definition) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Views below provides the formal summary, definitions, and terminology requirements.
Note that the “Differential Table” displays elements unique to this profile and the “Key Elements Table” displays a combined view of elements for this profile and the US Core Vital Signs Profile.

Each Observation Must Have:

  1. a patient
  2. a fixed code for systolic and diastolic blood pressure panel
  3. a fixed component code for systolic blood pressure
  4. a fixed component code for diastolic blood pressure

Each Observation Must Support:

  1. a result value for systolic blood pressure
  2. a result value for diastolic blood pressure

Profile Specific Implementation Guidance:

  • Note that this profile also conforms to the base FHIR Vital Signs Profile.
  • The observations MAY have additional codes that translate or map to the Observation code or category codes. For example:
    • providing a local system-specific code
    • providing more specific codes such as 8306-3 - Body height - lying in addition to 8302-2 - Body height. Several additional observation codes are provided in the FHIR core specification vital signs table.

    A code system value SHOULD be supplied for each additional code.

  • The observations MAY have component observations. For example, to qualify the vital sign observation, 8310-5 - Body temperature, 8327-9 - Body temperature measurement site (oral, forehead, rectal, etc.) may be used as a component observation. Several of these are provided in the FHIR core specification vital signs table.
  • Implementers may use this profile as a base for other vital signs in addition to those in this guide.
  • Because the blood pressure values are communicated in the mandatory systolic and diastolic components:
    • the Observation.value[x] element SHOULD be omitted
    • an Observation without a systolic or diastolic result value, SHALL include a reason why the data is absent in Observation.component.dataAbsentReason
    • All server systems - including those that never provide a component observation without a value - SHALL support Observation.component.dataAbsentReason for the components.
