醫療資訊系統改善—緊急通報機制與入口網站瀏覽紀錄

Abstract

本論文架構於台大醫院的健康資訊系統之下，主要設計了兩個改善健康資訊系統的機制：入口網站瀏覽紀錄以及緊急通報系統。 瀏覽紀錄機制將使用者在入口網站上的所有瀏覽點選行為記錄到遠端常駐程式的資料表中，並使用LRU 演算法分析出每位使用者最常使用的一些連結。這些連結會利用.NET Remoting 網路通訊技術從遠端常駐程式的資料表中讀出，並產生一組捷徑連結集合，顯示在入口網站的頁面上供使用者快速選取其常用連結。 緊急通報系統幫助使用者快速且有效率地利用簡訊通報相關醫療人員一些緊急情況。利用此系統，各病人或病歷的相關醫療人員通訊資料可快速取得並自動填入簡訊接收者欄位，使用者即可輕鬆地編輯修改簡訊內容。之後，此系統將簡訊及相關資訊寫入資料庫，簡訊中心即可根據資料庫的內容傳送簡訊。另外，緊急通報系統還支援了簡訊追蹤及回覆功能：傳送者可以查詢其傳送的簡訊接收狀態；接收者也可以利用手機回傳簡訊以告知其已得知該通報內容。

The thesis presents the architectures and implementations of two mechanisms: Log-based portal and Emergency Reporting System. The mechanisms are designed to enhance the HIS (Healthcare Information System) in NTUH (National Taiwan University Hospital). The Log-based portal logs users’ behaviors into data tables, and analyzes each user’s popular function links by adopting LRU (Least Recent Used) algorithm. The frequently executed links will be collected and retrieved as a list of links on the Portal page via .NET Remoting technique. In addition, the pre-fetched links are cached in advance to promote navigating performance. The Emergency Reporting System provides a user-friendly interface to assist users in sending the alert SMS (Short Message Service) messages efficiently and automatically. As a result, user can edit the SMS messages easily, correctly. The messages, i.e., receiver, message content, etc, will be written into HIS database tables, and be delivered by the SMS Center as well. In addition, the mechanism supports tracking and replying features. Thus, senders can acknowledge the acceptances of the receivers, and the receivers can perform the confirmations to ensure the alerts have been read.
