FHIR リソースの作成と管理

このページでは、FHIR リソースの作成、更新、パッチ適用、表示、一覧表示、取得、削除を行う方法を説明します。

FHIR リソースには、患者、デバイス、モニタリングなどに関するデータを含めることができます。FHIR リソースの一覧については、FHIR リソースインデックス（DSTU2、STU3、R4）をご覧ください。

このページの curl と PowerShell のサンプルは R4 FHIR ストアで動作し、DSTU2 または STU3 の FHIR ストアを使用している場合には動作が保証されません。DSTU2 または STU3 の FHIR ストアを使用している場合は、公式の FHIR ドキュメントで、サンプルをお使いの FHIR バージョンに変換する方法をご確認ください。

Go、Java、Node.js、Python のサンプルは STU3 FHIR ストアで動作します。

FHIR リソースの作成

FHIR リソースを作成する前に、FHIR ストアを作成する必要があります。

curl、PowerShell、Python のサンプルでは、次の FHIR リソースを作成する方法を示しています。

Patient（DSTU2、STU3、R4）リソース
Patient の Encounter（DSTU2、STU3、R4）リソース
Encounter の Observation（DSTU2、STU3、R4）リソース

その他のすべての言語のサンプルでは、汎用 FHIR リソースの作成方法を示しています。

詳細については、projects.locations.datasets.fhirStores.fhir.create をご覧ください。

以下の curl と PowerShell のサンプルは、R4 FHIR ストアで動作します。Go、Java、Node.js、Python のサンプルは STU3 FHIR ストアで動作します。

REST

リクエストのデータを使用する前に、次のように置き換えます。

PROJECT_ID: Google Cloud プロジェクトの ID
LOCATION: データセットの場所
DATASET_ID: FHIR ストアの親データセット
FHIR_STORE_ID: FHIR ストア ID

リクエストの本文（JSON）:

{
  "name": [
    {
      "use": "official",
      "family": "Smith",
      "given": [
        "Darcy"
      ]
    }
  ],
  "gender": "female",
  "birthDate": "1970-01-01",
  "resourceType": "Patient"
}

リクエストを送信するには、次のいずれかのオプションを選択します。

curl

注: 次のコマンドは、gcloud init または gcloud auth login を実行して、ユーザーアカウントで gcloud CLI にログインしているか、Cloud Shell を使用して自動的に gcloud CLI にログインしていることを前提としています。gcloud auth list を実行すると、現在アクティブなアカウントを確認できます。

リクエスト本文を request.json という名前のファイルに保存します。ターミナルで次のコマンドを実行して、このファイルを現在のディレクトリに作成または上書きします。

cat > request.json << 'EOF'
{
  "name": [
    {
      "use": "official",
      "family": "Smith",
      "given": [

      ]
    }
  ],
  "gender": "female",
  "birthDate": "1970-01-01",
  "resourceType": "Patient"
}
EOF

その後、次のコマンドを実行して REST リクエストを送信します。

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/fhir+json" \

FHIR リソースを条件付きで作成する

次の curl サンプルは、projects.locations.datasets.fhirStores.fhir.create メソッドを使用して FHIR リソースを条件付きで作成する方法を示しています。このメソッドは、FHIR 条件付き create インタラクション（DSTU2、STU3、R4）を実装します。

条件付き作成を使用すると、重複する FHIR リソースの作成を回避できます。たとえば、FHIR サーバーの各患者リソースには、通常、医療記録番号（MRN）などの一意の識別子があります。新しい Patient リソースを作成し、同じ MRN を持つ Patient リソースが存在しないようにするには、検索クエリを使用して新しいリソースを条件付きで作成します。Cloud Healthcare API は、検索クエリで一致がない場合にのみ新しいリソースを作成します。

サーバーのレスポンスは、検索クエリに一致したリソースの数によって異なります。

一致する	HTTP レスポンスコード	動作
ゼロ	`201 CREATED`	新しいリソースを作成します。
一つ	`200 OK`	新しいリソースは作成されません。
複数	`412 Precondition Failed`	新しいリソースは作成されず、`"search criteria are not selective enough"` エラーが返されます。

create インタラクションの代わりに条件付き create インタラクションを使用するには、リクエストに FHIR 検索クエリを含む If-None-Exist HTTP ヘッダーを指定します。

If-None-Exist: FHIR_SEARCH_QUERY

Cloud Healthcare API v1 では、条件付きオペレーションは identifier 検索パラメータのみを使用し（FHIR リソースタイプに存在する場合）、条件付き検索クエリと一致する FHIR リソースを決定します。

REST

次のサンプルは、If-None-Exist: identifier=my-code-system|ABC-12345 HTTP ヘッダーを使用して Observation リソースを作成する方法を示しています。Cloud Healthcare API は、クエリ identifier=my-code-system|ABC-12345 に一致する既存の Observation リソースがない場合にのみリソースを作成します。

curl -X POST \
  -H "Authorization: Bearer $(gcloud auth print-access-token)" \
  -H "Content-Type: application/fhir+json" \
  -H "If-None-Exist: identifier=my-code-system|ABC-12345" \
  -d @request.json \
  "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Observation"

次のサンプル出力は、意図的に失敗したリクエストを示しています。成功したリクエストからのレスポンスを表示するには、FHIR リソースの作成をご覧ください。

複数の Observation リソースがクエリに一致する場合、Cloud Healthcare API は次のレスポンスを返し、条件付き作成リクエストは失敗します。

  "issue": [
    {
      "code": "conflict",
      "details": {
        "text": "ambiguous_query"

    }
  ],
  "resourceType": "OperationOutcome"
}

FHIR リソースの更新

次のサンプルは、projects.locations.datasets.fhirStores.fhir.update メソッドを使用して FHIR リソースを更新する方法を示しています。このメソッドには、FHIR 標準更新インタラクション（DSTU2、STU3、R4）を実装します。

リソースを更新すると、そのリソースのコンテンツ全体が更新されます。これは、リソースの一部のみを更新するリソースのパッチ適用とは対照的です。

FHIR ストアに enableUpdateCreate が設定されていると、リソースが存在する場合、または存在せず指定された ID でリソースを挿入する場合は、リクエストはリソースを更新する Upsert（Update または Insert）として扱われます。

リクエストの本文には、JSON エンコードされた FHIR リソース、リクエストヘッダーには Content-Type: application/fhir+json を含める必要があります。リソースには、リクエストの REST パスの ID と同じ値を持つ id 要素を含める必要があります。

以下の curl と PowerShell のサンプルは、R4 FHIR ストアで動作します。Go、Java、Node.js、Python のサンプルは STU3 FHIR ストアで動作します。

FHIR リソースのパッチ適用

次のサンプルは、projects.locations.datasets.fhirStores.fhir.patch メソッドを呼び出して FHIR リソースにパッチを適用する方法を示しています。このメソッドには、FHIR 標準パッチ適用インタラクション（DSTU2、STU3、R4）を実装します。

リソースにパッチを適用するときは、JSON パッチのドキュメントで指定された操作を利用してリソースの一部を更新します。

リクエストには JSON パッチドキュメント、リクエストヘッダーには Content-Type: application/json-patch+json を含める必要があります。

次のサンプルは、Observation リソースにパッチを適用する方法を示しています。患者の 1 分あたりの心拍数（BPM）の Observation は、replace パッチオペレーションを使用して更新されます。

以下の curl と PowerShell のサンプルは、R4 FHIR ストアで動作します。Go、Java、Node.js、Python のサンプルは STU3 FHIR ストアで動作します。

リクエストのデータを使用する前に、次のように置き換えます。

PROJECT_ID: Google Cloud プロジェクトの ID
LOCATION: データセットの場所
DATASET_ID: FHIR ストアの親データセット
FHIR_STORE_ID: FHIR ストア ID
OBSERVATION_ID: Observation リソース ID
BPM_VALUE: パッチ適用された Observation リソースの 1 分あたりの心拍数（BPM）

リクエストの本文（JSON）:

FHIR バンドルでの `PATCH` リクエストの実行

FHIR バンドルで PATCH リクエストを指定できます（FHIR R4 のみ）。FHIR バンドルで PATCH リクエストを実行すると、FHIR リソースごとに個別のパッチリクエストを行う必要がなく、複数の FHIR リソースに一度にパッチを適用できます。

一括で PATCH リクエストを行うには、リクエスト内の resource オブジェクトで次の情報を指定します。

Binary に設定された resourceType フィールド
application/json-patch+json に設定された contentType フィールド
base64 でエンコードされたパッチ本文

resource オブジェクトが次のように見えるようにします。

"resource": {
  "resourceType": "Binary",
  "contentType": "application/json-patch+json",
  "data": "WyB7ICJvcCI6ICJyZXBsYWNlIiwgInBhdGgiOiAiL2JpcnRoRGF0ZSIsICJ2YWx1ZSI6ICIxOTkwLTAxLTAxIiB9IF0K"
}

次の例は、data フィールドで base64 にエンコードされたパッチ本文を示しています。

[
  {
    "op": "replace",
    "path": "/birthdate",
    "value": "1990-01-01"
  }
]

次のサンプルでは、PATCH リクエストを一括で使用して、1990-01-01 のbirthDate 値を取得するために、FHIR リソースの作成で作成した Patient リソースにパッチを適用する方法を説明します。

リクエストのデータを使用する前に、次のように置き換えます。

PROJECT_ID: 実際の Google Cloud プロジェクト ID
LOCATION: 親データセットの場所
DATASET_ID: FHIR ストアの親データセット
FHIR_STORE_ID: FHIR ストア ID
PATIENT_ID: 既存の Patient リソースの ID

リクエストの本文（JSON）:

{
  "type": "transaction",
  "resourceType": "Bundle",
  "entry": [
    {
      "request": {
        "method": "PATCH",
        "url": "Patient/PATIENT_ID"
      },
      "resource": {
        "resourceType": "Binary",
        "contentType": "application/json-patch+json",
        "data": "WyB7ICJvcCI6ICJyZXBsYWNlIiwgInBhdGgiOiAiL2JpcnRoRGF0ZSIsICJ2YWx1ZSI6ICIxOTkwLTAxLTAxIiB9IF0K"
      }
    }
  ]
}

リクエストを送信するには、次のいずれかのオプションを選択します。

curl

cat > request.json << 'EOF'
{
  "type": "transaction",
  "resourceType": "Bundle",
  "entry": [
    {
      "request": {

      }
    }
  ]
}

次のサンプルは、projects.locations.datasets.fhirStores.fhir.conditionalPatch メソッドを呼び出して、ID でリソースを特定するのではなく、検索クエリで一致する FHIR リソースにパッチを適用する方法を示しています。このメソッドは、FHIR 標準条件付きパッチ適用インタラクション（DSTU2、STU3、R4）を実装します。

条件付きパッチを適用できるのは、一度に 1 つのリソースのみです。検索条件が複数件と一致した場合、リクエストは 412 Precondition Failed エラーを返します。

REST

次のサンプルは、Observation の識別子が my-code-system の ABC-12345 の場合に、curl と PowerShell を使用して PATCH リクエストを送信し、Observation リソースを編集する方法を示しています。患者の 1 分あたりの心拍数（BPM）の Observation は、replace パッチオペレーションを使用して更新されます。

リクエストのデータを使用する前に、次のように置き換えます。

PROJECT_ID: Google Cloud プロジェクトの ID
LOCATION: データセットの場所
DATASET_ID: FHIR ストアの親データセット
FHIR_STORE_ID: FHIR ストア ID
BPM_VALUE: Observation リソースの 1 分あたりの心拍数（BPM）

リクエストの本文（JSON）:

[
  {
    "op": "replace",
    "path": "/valueQuantity/value",
    "value": BPM_VALUE
  }
]

リクエストを送信するには、次のいずれかのオプションを選択します。

curl

cat > request.json << 'EOF'
[
  {
    "op": "replace",
    "path": "/valueQuantity/value",
    "value": BPM_VALUE
  }
]
EOF

その後、次のコマンドを実行して REST リクエストを送信します。

curl -X PATCH \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json-patch+json" \
     -d @request.json \

FHIR リソースを条件付きで削除する

クエリで identifier 検索パラメータを使用して複数の FHIR リソースと一致する場合、Cloud Healthcare API は "412 - Condition not selective enough" エラーを返します。リソースを個別に削除する手順は次のとおりです。

各リソースを検索して、サーバーから割り当てられた一意の ID を取得します。
ID を使用して各リソースを個別に削除します。

次のサンプルは、ID で FHIR リソースを特定するのではなく、検索クエリで一致する FHIR リソースを条件付きで削除する方法を示しています。検索クエリは、Observation の識別子（my-code-system の ABC-12345）を使用して Observation リソースを照合して削除します。

projects.locations.datasets.fhirStores.fhir.Resource-purge メソッドの呼び出しは、roles/healthcare.fhirStoreAdmin ロールを持つユーザー（呼び出し元）に限定されています。roles/healthcare.fhirResourceEditor ロールを持つユーザーはこのメソッドを呼び出すことができません。呼び出し元が FHIR リソースの履歴バージョンを削除できるようにするには、次のいずれかを行います。

呼び出し元に roles/healthcare.fhirStoreAdmin のロールがあることを確認する。
healthcare.fhirResources.purge 権限を持つカスタム IAM ロールを作成し、そのロールを呼び出し元に割り当てる。

このサンプルは、FHIR リソースの作成で作成したリソースを使用して、Observation リソースのすべてのバージョンを削除する方法を示しています。

以下の curl と PowerShell のサンプルは、R4 FHIR ストアで動作します。Go、Java、Node.js、Python のサンプルは STU3 FHIR ストアで動作します。

curl

FHIR リソースのすべての履歴バージョンを削除するには、DELETE リクエストを送信して次の情報を指定します。

親データセットの名前
FHIR ストアの名前
リソースのタイプと ID
アクセストークン

次のサンプルは、curl を使用した DELETE リクエストを示しています。

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     -H "Content-Type: application/fhir+json; charset=utf-8" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/RESOURCE_TYPE/RESOURCE_ID/\$purge"

リクエストが成功すると、サーバーは JSON 形式の空のレスポンス本文を返します。

{}

PowerShell

FHIR リソースのすべての履歴バージョンを削除するには、DELETE リクエストを送信して次の情報を指定します。

親データセットの名前
FHIR ストアの名前
リソースのタイプと ID
アクセストークン

次のサンプルは、Windows PowerShell を使用した DELETE リクエストを示しています。

$cred = gcloud auth application-default print-access-token
$headers = @{ Authorization = "Bearer $cred" }

Invoke-RestMethod `
  -Method Delete `
  -Headers $headers `
  -ContentType: "application/fhir+json; charset=utf-8" `
  -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/RESOURCE_TYPE/RESOURCE_ID/$purge" | ConvertTo-Json

リクエストが成功すると、サーバーは JSON 形式の空のレスポンス本文を返します。
