建立及管理 HL7v2 訊息

本頁說明如何擷取、建立、標記、列出、查看及刪除 HL7v2 訊息。HL7v2 訊息用於在系統之間傳輸臨床資料。HL7v2 訊息可能包含觀察結果、要傳送給藥局的處方、金融交易或其他臨床事件的相關資訊。

建立及擷取 HL7v2 訊息的簡介

如要在 Cloud Healthcare API 中儲存 HL7v2 訊息，請使用下列任一方法：

使用 messages.ingest 時，這個方法會產生包含下列其中一項內容的回應：

  • 成功時的 HL7v2 應答 (ACK) 訊息
  • 發生錯誤時的否定確認 (NACK) 訊息

ACK 和 NACK 訊息用於回覆預期收到這些確認訊息的 HL7v2 介面系統。

使用 MLLP 介面卡擷取及建立訊息

醫療照護系統與 Cloud Healthcare API 之間會使用基本較低層通訊協定 (MLLP) 傳送 HL7v2 訊息。詳情請參閱「MLLP and the Google Cloud Platform MLLP adapter」。如要瞭解如何設定 MLLP 配接器，與 Cloud Healthcare API 進行安全通訊，請參閱「透過 TCP/IP 連線傳送 HL7v2 訊息」。

擷取 HL7v2 訊息

Cloud Healthcare API 從照護系統擷取訊息後，會產生包含 hl7ack 欄位的回應，其中包含經過 Base64 編碼的 HL7v2 訊息，並具有下列特徵：

  • 訊息類型為 ACK。
  • 傳送設施和接收設施會反向運作，傳送應用程式和接收應用程式也會反向運作。
  • 郵件的傳送時間為目前時間，且系統會產生新的控制 ID。
  • MSH-9.1 欄位的值會定義訊息類型。
  • MSA.1 欄位的值會定義回應類型。AA 回應類型表示 Application Accept，也就是說，系統已驗證並成功擷取訊息。
  • MSA.2 值包含原始訊息的控制項 ID。

下列範例說明如何使用 projects.locations.datasets.hl7V2Stores.messages.ingest 方法擷取 HL7v2 訊息。

curl

如要擷取 HL7v2 訊息，請提出 POST 要求並指定下列資訊：

  • 父項資料集的名稱和位置
  • HL7v2 儲存庫名稱
  • A Message

下列範例顯示使用 curl 的 POST 要求，以及名為「hl7v2-sample.json」的 JSON 檔案範例。

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     --data-binary @hl7v2-sample.json \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages:ingest"

建立 HL7v2 訊息

下列範例說明如何使用 projects.locations.datasets.hl7V2Stores.messages.create 方法建立 HL7v2 訊息。

REST

如要建立 HL7v2 訊息，請使用 projects.locations.datasets.hl7V2Stores.messages.create 方法。

如需搭配範例指令使用的 HL7v2 訊息檔案，可以下載 hl7v2-sample.json JSON 檔案。

使用任何要求資料之前，請先替換以下項目：

  • PROJECT_ID：您的 Google Cloud 專案 ID
  • LOCATION：資料集位置
  • DATASET_ID：HL7v2 存放區的父項資料集
  • HL7V2_STORE_ID：HL7v2 儲存庫 ID
  • HL7V2_MESSAGE_FILE：本機上包含 HL7v2 訊息的 JSON 格式檔案路徑

如要傳送要求，請選擇以下其中一個選項：

curl

執行下列指令：

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     --data-binary @HL7V2_MESSAGE_FILE \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages"

PowerShell

執行下列指令：

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

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -InFile HL7V2_MESSAGE_FILE `
    -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages" | Select-Object -Expand Content

APIs Explorer

開啟方法參考頁面。系統會在頁面右側開啟 APIs Explorer 面板。您可以使用這項工具來傳送要求。完成任何必填欄位，然後按一下「執行」。

使用 hl7v2-sample.json JSON 檔案建立訊息時，系統會傳回下列輸出內容：

Go

import (
	"context"
	"encoding/base64"
	"fmt"
	"io"
	"os"

	healthcare "google.golang.org/api/healthcare/v1"

HL7v2 訊息區段分隔符和編碼

HL7v2 的預設區段分隔符為回車符 (\r)。大多數文字編輯器會使用換行符 (\n) 做為區段分隔符。這會產生 HL7v2 訊息，無法使用預設設定擷取至 Cloud Healthcare API。如要允許 HL7v2 儲存庫擷取使用換行字元做為區段分隔符的訊息，請參閱設定區段結束字元。

如要將檔案中的換行字元轉換為歸位字元，請在 Linux 殼層中執行下列指令：

sed -z 's/\n/\r/g' INPUT_FILENAME > OUTPUT_FILENAME

擷取和建立方法會將 HL7v2 訊息視為 Base64 編碼字串。如要將字串轉換為 Base64 編碼，請在 Linux 殼層中執行下列指令：

openssl base64 -A -in ./INPUT_FILENAME -out ./OUTPUT_FILENAME

設定區段結束字元

建立或擷取資料時，HL7v2 訊息格式要求使用回車字元 \r 結束區段。您可以將 HL7v2 儲存庫設定成接受使用非標準結束字元的 HL7v2 訊息，例如 \n。

請參考下列 HL7v2 訊息，其中使用預設的 \r 做為區段結束字元。建立 HL7v2 儲存庫時，系統預設會接受這類訊息。

MSH|^~\\&|FROM_APP|FROM_FACILITY|TO_APP|TO_FACILITY|20150503223000||ADT^A01|20150503223000|P|2.5|\r

PV1||I|H73 RM1^1^^HIGHWAY 73 CLINIC||||5148^MARY QUINN|||||||||Y||||||||||||||||||||||||||||20150503223000|\r

下列訊息與前一則訊息相同，但使用 \n 做為區隔終止符：

MSH|^~\\&|FROM_APP|FROM_FACILITY|TO_APP|TO_FACILITY|20150503223000||ADT^A01|20150503223000|P|2.5|\n

PV1||I|H73 RM1^1^^HIGHWAY 73 CLINIC||||5148^MARY QUINN|||||||||Y||||||||||||||||||||||||||||20150503223000|\n

如要儲存使用非標準結束字元的訊息，請在 HL7v2 儲存庫中設定 ParserConfig 物件，並將 segmentTerminator 欄位設為 \n 的 base64 編碼。

下列範例說明如何建立 HL7v2 儲存庫時，在 ParserConfig 中設定 segmentTerminator。如果您已有 HL7v2 儲存庫，可以編輯該儲存庫，提供 ParserConfig 主體。設定區隔終止符後，即可建立或擷取訊息。

curl

如要建立 HL7v2 儲存庫，並將區段結束字元設為 \n，請提出 POST 要求並指定下列資訊：

  • 父項資料集的名稱和位置
  • HL7v2 儲存庫名稱
  • parserConfig 物件，且 segmentTerminator 設為 Cg== (\n 的 Base64 編碼)

以下範例顯示如何使用 curl 發出 POST 要求。

curl -X POST \
    --data "{
      'parserConfig': {
        'segmentTerminator': 'Cg=='
      }
    }" \
    -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores?hl7V2StoreId=HL7V2_STORE_ID"

如果要求成功，伺服器會以 JSON 格式傳回回應：

{
  "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID",
  "parserConfig": {
    "segmentTerminator": "Cg=="
  }
}

PowerShell

如要建立 HL7v2 儲存庫，並將區段結束字元設為 \n，請提出 POST 要求並指定下列資訊：

  • 父項資料集的名稱和位置
  • HL7v2 儲存庫名稱
  • parserConfig 物件，且 segmentTerminator 設為 Cg== (\n 的 Base64 編碼)

以下範例顯示如何使用 PowerShell 提出 POST 要求。

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

  -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores?hl7V2StoreId=HL7V2_STORE_ID" | Select-Object -Expand Content

  "parserConfig": {
    "segmentTerminator": "Cg=="
  }
}

使用空值區隔標頭

如果 HL7v2 訊息沒有訊息標頭區段 (MSH)，就會有空值區段標頭。一般來說，HL7v2 訊息會包含 MSH，用於定義訊息的來源、意圖、目的和目的地等中繼資料。MSH 可讓您搜尋及篩選訊息。不過，您可以設定 HL7v2 儲存庫中的 ParserConfig 物件，並將 allowNullHeader 欄位設為 true，即可儲存不含 MSH 的訊息。

下列範例訊息包含病患 ID (PID) 區段，但沒有 MSH：

PID|1||21004053^^^^MRN||SULLY^BRIAN||19611209|M|||123 MAIN ST^^MOUNTAIN SPRINGS^CO^80439

下列範例說明如何建立 HL7v2 儲存庫時，在 ParserConfig 中設定 allowNullHeader。如果您有現有的 HL7v2 儲存庫，可以編輯並提供 ParserConfig 主體。將 allowNullHeader 設為 true 後，您就可以建立或擷取含有空值區隔標題的訊息。

curl

如要建立 HL7v2 儲存庫並儲存不含 MSH 的訊息，請提出 POST 要求並指定下列資訊：

  • 父項資料集的名稱和位置
  • HL7v2 儲存庫名稱
  • parserConfig 物件，且 allowNullHeader 設為 true

以下範例顯示如何使用 curl 發出 POST 要求。

curl -X POST \
    --data "{
      'parserConfig': {
        'allowNullHeader': true
      }
    }" \

    -H "Content-Type: application/json; charset=utf-8" \
    "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores?hl7V2StoreId=HL7V2_STORE_ID"

如果要求成功，伺服器會以 JSON 格式傳回回應：

  "parserConfig": {
    "allowNullHeader": true
  }
}

PowerShell

  }
}

為 HL7v2 訊息加上標籤

您可以在訊息中新增一或多個鍵/值標籤。標籤的用途之一是為郵件加上狀態標籤，讓應用程式可以依狀態查詢郵件。

下列範例說明如何使用 projects.locations.datasets.hl7V2Stores.messages.patch 方法，為 HL7v2 訊息新增標籤。

curl

如要為 HL7v2 訊息新增標籤，請提出 PATCH 要求，並指定下列資訊：

  • 父項資料集的名稱和位置
  • HL7v2 儲存庫名稱
  • 訊息 ID
  • 要更新的標籤資料
  • 更新遮罩

以下範例顯示如何使用 curl 發出 PATCH 要求。

curl -X PATCH \

取得 HL7v2 訊息內容

下列範例說明如何使用 projects.locations.datasets.hl7V2Stores.messages.get 方法取得 HL7v2 訊息的內容。如要判斷要擷取郵件的哪些部分，請使用下列其中一個選項提供 view 查詢參數：

  • BASIC：僅包含 name 欄位。
  • RAW_ONLY：包含所有訊息欄位，但 parsedData 欄位除外。
  • PARSED_ONLY：包含所有訊息欄位，但 data 欄位除外。
  • FULL：包含所有訊息欄位。這是目前的預設做法。

下列範例說明如何使用 FULL、RAW_ONLY 和 PARSED_ONLY 檢視畫面取得 HL7v2 訊息內容。

使用 FULL 檢視畫面

您不需要明確設定 FULL 檢視畫面，因為 FULL 是預設值。不過，在下列 curl 和 PowerShell 範例中，為求完整，FULL 檢視畫面會以查詢參數的形式新增。

curl

如要使用 FULL 檢視畫面取得 HL7v2 訊息內容，請提出 GET 要求並指定下列資訊：

  • 父項資料集的名稱和位置
  • HL7v2 儲存庫名稱
  • 訊息 ID
  • FULL，例如view

以下範例顯示如何使用 curl 發出 GET 要求。

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages/MESSAGE_ID?view=FULL"

        }
      }
    ]
  }
}

如要使用 FULL 檢視畫面取得 HL7v2 訊息內容，請提出 GET 要求並指定下列資訊：

  • 父項資料集的名稱和位置
  • HL7v2 儲存庫名稱
  • 訊息 ID

刪除 HL7v2 訊息

下列範例說明如何使用 projects.locations.datasets.hl7V2Stores.messages.delete 方法刪除 HL7v2 訊息。

curl

如要刪除 HL7v2 訊息，請提出 DELETE 要求，並指定下列資訊：

  • 父項資料集的名稱和位置
  • HL7v2 儲存庫名稱
  • HL7v2 訊息 ID

以下範例顯示如何使用 curl 發出 DELETE 要求。

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/hl7V2Stores/HL7V2_STORE_ID/messages/MESSAGE_ID"

如果要求成功，伺服器會以 JSON 格式傳回空白主體的回應：

PowerShell

如要刪除 HL7v2 訊息，請提出 DELETE 要求，並指定下列資訊：
