            "coding":  [
                {
                    "system": "http://snomed.info/sct",

type Reference(Group Device UKCorePractitioner NHSDigitalPatient)

Definition

A reference to a NHSDigital-Patient and/or an identifier reference using NHSNumber. Only traced NHS Numbers may be used.


    "subject": {
        "reference": "urn:uuid:edea022a-2d81-11eb-adc1-0242ac120002",
        "identifier": [

    },

Preference is for a reference to a Patient resource, however current document flows may only support limited metadata.

Constraints

  • patient-reference (WARNING) subject - An identifier reference or resource reference must be provided
  • patient-nhs (ERROR) Supplied NHS Number is outside the English and Welsh NHS Number range or length of the number is wrong.

Identifies the logical organization (software system, vendor, or department) to go to find the current version, where to report issues, etc. This is different from the physical location (URL, disk drive, or server) of the document, which is the technical location of the document, which host may be delegated to the management of some other organization.

content.attachment
Element Id DocumentReference.content.attachment
Cardinality 1..1
type Attachment

Definition

The document or URL of the document along with critical metadata to prove content has integrity.

content.attachment.data
Element Id DocumentReference.content.attachment.data
Cardinality 0..1
type base64Binary

Definition

SHOULD not be used. Use url to link to the actual document

Requirements

The data needs to able to be transmitted inline.

Comment

The base64-encoded data SHALL be expressed in the same character set as the base resource XML or JSON.

content.attachment.url
Element Id DocumentReference.content.attachment.url
Cardinality 0..1
type url

Definition

For REST interactions this MUST be a url to the actual document. For messaging interactions this must be an internal resource reference to the actual document.

Requirements

The data needs to be transmitted by reference.

Comment

If both data and url are provided, the url SHALL point to the same content as the data contains. Urls may be relative references or may reference transient locations such as a wrapping envelope using cid: though this has ramifications for using signatures. Relative URLs are interpreted relative to the service url, like a resource reference, rather than relative to the resource itself. If a URL is provided, it SHALL resolve to actual data.

context
Element Id DocumentReference.context
Cardinality 0..1
type BackboneElement

Definition

The clinical context in which the document was prepared.

"context": {
        "related" : [
            {
                "type": "ServiceRequest",
                "reference": "ServiceRequest/be735573-9f24-42e1-ae98-af89d632e4bf"

These values are primarily added to help with searching for interesting/relevant documents.

context.practiceSetting
Element Id DocumentReference.context.practiceSetting
Cardinality 0..1

Definition

It is recommended a care setting code should be provided

Requirements

This is an important piece of metadata that providers often rely upon to quickly sort and/or filter out to find specific content.

Comment

This element should be based on a coarse classification system for the class of specialty practice. Recommend the use of the classification system for Practice Setting, such as that described by the Subject Matter Domain in LOINC.
