Resource Profile: NP Core Blood Pressure Observation

Official URL: http://fhir.digitalhealth.gov.np/core/StructureDefinition/np-core-blood-pressure-observation Version: 1.0.0
Active as of 2026-10-14 Computable Name: NPCoreBloodPressureObservation

Sets minimum expectations for blood pressure observations in the NP Core. Derives from the FHIR Blood Pressure vital signs profile, which fixes the panel LOINC code (85354-9), the systolic (8480-6) and diastolic (8462-4) component codes, and constrains the component values to UCUM mm[Hg].

Constraints

Id Grade Path(s) Description Expression
dom-2 error Observation If the resource is contained in another resource, it SHALL NOT contain nested Resources contained.contained.empty()
dom-3 error Observation If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()
dom-4 error Observation If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()
dom-5 error Observation If a resource is contained in another resource, it SHALL NOT have a security label 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()
sqty-1 error Observation.referenceRange.low, Observation.referenceRange.high The comparator is not used on a SimpleQuantity comparator.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 If there is no a value a data absent reason must be present value.exists() or dataAbsentReason.exists()
