Profile for capturing blood pressure value as FHIR Observation resources.
This profile defines the exchange of blood pressure value data for the Mandatory Interoperable Value (MIV) "Blood Pressure Monitoring" which is technically defined by the ValueSet hddt-miv-blood-pressure-value. This MIV is e.g. implemented by automated sphygmomanometers (oszillometric, auscultatory) that can connect to a Personal Health Gateway (e.g. a mobile app for tracking blood pressure values) through wireless communication.
Blood pressure measurements consist of multiple components: systolic blood pressure, diastolic blood pressure, and optionally mean blood pressure. This profile uses the LOINC panel code #85354-9 “Blood pressure panel with all children optional” defined in the MIV hddt-miv-blood-pressure-value to represent the complete measurement.
Obligations and Conventions:
Each Blood Pressure Measurement MUST hold a reference to a Personal Health Device Device resource. Blood pressure devices typically do not require calibration.
This profile inherits from the FHIR Blood Pressure profile (http://hl7.org/fhir/StructureDefinition/bp) and adds HDDT-specific constraints. The blood pressure components
(systolic and diastolic are mandatory; mean is optional) are inherited from the parent profile with the MeanBP component added as an optional slice.
Each component MUST include a value in mmHg (millimeters of mercury).
Caution: For privacy and data protection, the subject reference MUST only use pseudonymized or anonymized identifiers. Direct patient identification is not permitted.
Constraints applied:
status is restricted to finalcode.coding[BPCode] is constrained to ValueSet HddtMivBloodPressureValue containing LOINC panel code 85354-9component cardinality is set to 2..3 to require systolic and diastolic components (inherited from parent), with mean blood pressure as optionalcomponent[MeanBP] is added as an optional slice (0..1) for mean blood pressure with LOINC code 8478-0valueQuantity MUST use UCUM code mm[Hg] for the unitdevice is mandatory and restricted to reference only HddtPersonalHealthDeviceUsages:

contained.meta.security.empty()
|
| dom-6 | best practice | Observation | A resource should have narrative for robust management |
text.`div`.exists()
|
| ele-1 | error | **ALL** elements | All FHIR elements must have a @value or children |
hasValue() or (children().count() > id.count())
|
| ext-1 | error | **ALL** extensions | Must have either extensions or value[x], not both |
extension.exists() != value.exists()
|
| obs-3 | error | Observation.referenceRange | Must have at least a low or a high or text |
low.exists() or high.exists() or text.exists()
|
| obs-6 | error | Observation | dataAbsentReason SHALL only be present if Observation.value[x] is not present |
dataAbsentReason.empty() or value.empty()
|
| obs-7 | error | Observation | If Observation.code is the same as an Observation.component.code then the value element associated with the code SHALL NOT be present |
value.empty() or component.code.where(coding.intersect(%resource.code.coding).exists()).empty()
|
| vs-1 | error | Observation.effective[x] | if Observation.effective[x] is dateTime and has a value then that value shall be precise to the day |
$this is dateTime implies $this.toString().length() >= 10
|
| vs-2 | error | Observation | If there is no component or hasMember element then either a value[x] or a data absent reason must be present. |
(component.empty() and hasMember.empty()) implies (dataAbsentReason.exists() or value.exists())
|
| vs-3 | error | Observation.component, Observation.component:SystolicBP, Observation.component:DiastolicBP, Observation.component:MeanBP | If there is no a value a data absent reason must be present |
value.exists() or dataAbsentReason.exists()
