如何从 FHIR 服务器获取约会的子集？

Question

我正在从使用此模板的 FHIR 服务器检索 JSON 对象。它们看起来像这样：

  "resourceType": "Appointment",
  "id": "example",
  "text": {
    "status": "generated",
    "div": "\u003cdiv xmlns\u003d\"http://www.w3.org/1999/xhtml\"\u003eBrian MRI results discussion\u003c/div\u003e"
  },
  "status": "booked",
  "serviceCategory": [
    {
      "coding": [
        {
          "system": "http://example.org/service-category",
          "code": "gp",
          "display": "General Practice"
        }
      ]
    }
  ],
  "serviceType": [
    {
      "coding": [
        {
          "code": "52",
          "display": "General Discussion"
        }
      ]
    }
  ],
  "specialty": [
    {
      "coding": [
        {
          "system": "http://snomed.info/sct",
          "code": "394814009",
          "display": "General practice"
        }
      ]
    }
  ],
  "appointmentType": {
    "coding": [
      {
        "system": "http://terminology.hl7.org/CodeSystem/v2-0276",
        "code": "FOLLOWUP",
        "display": "A follow up visit from a previous appointment"
      }
    ]
  },
  "reasonReference": [
    {
      "reference": "Condition/example",
      "display": "Severe burn of left ear"
    }
  ],
  "priority": 5,
  "description": "Discussion on the results of your recent MRI",
  "start": "2013-12-10T09:00:00Z",
  "end": "2013-12-10T11:00:00Z",
  "created": "2013-10-10",
  "comment": "Further expand on the results of the MRI and determine the next actions that may be appropriate.",
  "basedOn": [
    {
      "reference": "ServiceRequest/myringotomy"
    }
  ],
  "participant": [
    {
      "actor": {
        "reference": "Patient/example",
        "display": "Peter James Chalmers"
      },
      "required": "required",
      "status": "accepted"
    },
    {
      "type": [
        {
          "coding": [
            {
              "system": "http://terminology.hl7.org/CodeSystem/v3-ParticipationType",
              "code": "ATND"
            }
          ]
        }
      ],
      "actor": {
        "reference": "Practitioner/example",
        "display": "Dr Adam Careful"
      },
      "required": "required",
      "status": "accepted"
    },
    {
      "actor": {
        "reference": "Location/1",
        "display": "South Wing, second floor"
      },
      "required": "required",
      "status": "accepted"
    }
  ],
  "meta": {
    "tag": [
      {
        "system": "http://terminology.hl7.org/CodeSystem/v3-ActReason",
        "code": "HTEST",
        "display": "test health data"
      }
    ]
  }
}

该资源是一个预约，我想获取具有特定演员的所有预约，所有特定患者或医生的预约。各个参与者嵌套在 JSON 对象中的几层。我不知道如何对这些嵌套元素执行 GET 请求。

我可以执行 GET 请求来获取这部分约会吗？或者通常的做法是获取所有约会并自己过滤它们？

Answer 1

您可以使用搜索选项来过滤 FHIR 查询的结果。此处列出了可用于过滤约会的参数，并且可以在此处找到有关创建搜索的规则

例如：

[base]/Appointment?actor=Patient/123&status=booked&date=ge2020-07-23

将为您提供从今天开始“预订”（即确认）的患者的所有未来预约。结果将是一个包含一堆条目的 Bundle 资源。每个条目将包含一个 Appointment 实例。
