为 FHIR 资源实例定义自定义属性

Question

我正在尝试为从业者资源定义自定义属性。但是当我根据我的结构定义验证一个实例时它失败了并且目前不知道我做错了什么：

{
    "resourceType": "StructureDefinition",
    "url": "http://example.com/fhir/StructureDefinition/PractitionerProfile",
    "name": "PractitionerProfile",
    "status": "active",
    "kind": "resource",
    "abstract": false,
    "type": "Practitioner",
    "baseDefinition": "http://hl7.org/fhir/StructureDefinition/Practitioner",
    "derivation": "specialization",
    "differential": {
        "element": [
            {
                "id": "Practitioner.telecom",
                "path": "Practitioner.telecom",
                "definition": "A contact detail for the practitioner, e.g. a telephone number or an email address.",
                "min": 1,
                "max": "1"
            },
            {
                "id": "Practitioner.foo",
                "path": "Practitioner.foo",
                "definition": "A contact detail for the practitioner, e.g. a telephone number or an email address.",
                "min": 1,
                "max": "1",
                "type": [{
                  "code": "string"
                }]
            }
        ]
    }
}

<Practitioner xmlns='http://hl7.org/fhir'>
    <meta>
        <profile value='http://example.com/fhir/StructureDefinition/PractitionerProfile' />
    </meta>
    <active value='true' />
    <foo value="bar"/>

        <value value='555-101-0987' />
        <use value='home' />
    </telecom>
</Practitioner>

添加自定义属性不符合要求。如果您有自定义要求，则需要使用 Practitioner.extension 并将您的元素定义为扩展数据类型的配置文件。看看https://build.fhir.org/extensibility
