RMIM 模型介紹

RIM 於應用之缺憾

使用 V3 方法論重新定義 RIM ，使其能夠產生

特定功能目的之物件。

1. RIM 為一般化抽象類別模型 (Class) 。2. 類別模型無法表達特定物件 (Object) 。

擴展 RIM 資訊** 限制循環

**

D-MIM Domain Message Information Model 延伸自 RIM 。 由特定領域 (domain) 負責建構。

例如“ Patient Administration” 。 會有多個“ entry points”(XML Root Element) 。 類別的部分屬性開始賦予內容值。

R-MIM Refined Message Information Model 衍生自 RIM ，是 D-MIM 之子集合。 類別的部分屬性會再多一些給定內容值。 只會有一個“ Entry Point” 連接到特定焦點

或主題類別。Patient Administration DMIM

實作概念

方法論步驟 HL7 工具的應用可分成三種步驟：

Scope 範疇Dynamic Model 動態模型Static Model 靜態模型

範疇 本步驟要回答下列三個問題：

What is communicated?What happens?Who is involved?

假設情境 A clinician, using a local medical office support

system, orders a lab test for one of her patients. The test will be performed on a specimen collected at her office. She will send the specimen by courier, and expects to receive a confirmation that the test will be performed, and a result of the test.

有位臨床醫師，使用辦公室支援系統為其病患開立一個檢驗醫令。此檢驗所需的檢體是在他的辦公室收集的。他利用派送者將檢體送出，並期望能收到對方的回覆，確認要執行此檢驗以及最後結果。

動態模型 動態模型包含兩個步驟：

(a) Blocking out the Interactions

(b) Documenting the Interactions

Blocking out the Interactions 從情境故事中擷取出交互作用，應先回答

下列問題：Who sends and receives?When to communicate?What is sent?Response obligations?

The right information to the right person at the right time

Blocking out the Interactions 情境故事

Initial order from MdOffice to LabMgmt; when the order is ready;

Content: patient, orderer, specimen, performer (lab), test; expect confirmation

Confirmation from LabMgmt to MdOffice; upon receipt and acceptance;

Content: order reference; performer; expected completion

Result from LabMgmt to MdOffice; when test done; Content: order reference; patient reference; findings; specimen

status

Documenting the Interactions 要完成事項包含：

A. 定義或找出發送端與接收端的應用角色B. 規範 “ trigger event” 作為溝通啟始C. 給予交互作用特性化D. 訊息類型之需求文件化

Documenting the Interactions 情境故事範例

A. MdOffice -> 1) Lab Order Placer; 2) Lab Confirmation Receiver; 3) Lab Observation Event Tracker; LabMgmt -> 1) Lab order fulfiller; 2) Lab Promise confirmer; 3) Lab Observation Event Informer

B. 1) Order activate; 2) Promise activate; 3) Event complete

C. 1) Request for action; 2) Request response; 3) Event notification

D. 1) Lab observation order; 2) Lab observation promise; 3) Lab observation event

情境假設

靜態模型 靜態模型包含三個步驟：

(a) Defining Subject-specific Information Model,

(b) Defining Message Design in an HMD

(c) Documenting the Message Design

Defining Subject-specific Information Model 應完成：

確認是屬於哪一個領域或則是使用哪一個 R-MIM 。

建立副本，設定其屬性與關連。從 D-MIM 中組合或收集。參照 “ Common” 型態 ( 共用模組）R-MIM 文件化存入儲存庫

Defining Message Design in an HMD 此步驟應包含：

Walking the graph to serialize the R-MIMDefining message types based on (within) the

HMDDefining R-MIM constraintsSaving to repositoryExpressing HMD as XML, and/or CSV files

Documenting the Message Design 最後步驟：

Publish designs in ExcelCreate schemasPublish in HTML
