急診護理完整暨智慧型檢傷無線PDA輔助系統之開發

The Development of Wireless PDA Support Systems for Comprehensive and Intelligent Triage in Emergency Nursing

本研究目的為根據國際上檢傷評估工作與研究的發展趨勢，剸展智慧型檢傷無線PDA輔助系統。環境選擇一教學中心之急診室，系統開發採密集性雛形開發法方式。系統架構包含PDA與PC工作站。兩者透過中心急診室內部無線網路連結。伺服程式以VB6.0設計，資料庫則使用微軟Access97 資料庫。系統內容之設計參考既有之「急診護理評估表」，並依據衛生署頒佈之檢傷分級準則建置一表格式知識庫，且PDA之界面設計亦採取特殊設計。完成之完整檢傷評估輔助系統官容共包含6大單元，29畫面，452項主要資訊登錄項目。就系統開發的挑戰而言，系統硬體困難度最低，其次則為軟體設計，不過皆可以克服。最大的困難點其實在於系統和實際工作流程的配合度。本系統極適合支援完整檢傷評估工作，且方便檢傷訓練與資料分析。本研究後續重點為系統實證檢驗。

The purpose of this study was to develop a wireless intelligent triage PDA support system based on the most up-to-date ideas in the design of a triage system. The system was designed for the Emergency Department of a medical center. An intensive prototyping approach was used for the system development. The system was composed of two key components: PDA and PC workstation. The Palm-based Visor Edge PDA was used due to its support of 802.11b wireless connection. The server-side program was coded in VB 6 with Access 97 database. The system was designed based on the Emergency Triage and Evaluation Form and was incorporated with a table-based triage acuity expert system based on the Triage Acuity Guidelines published by the Executive Yuan, Department of Health in Taiwan. The interface of the PDA system was specially designed to assure its ease of use. The completed system was composed of 29 key forms, organized into six categoriesbasic information, vital signs, traumatic complaints, non-traumatic complaints, nursing evaluation, and operational screens-with 452 information items. The most challenging part in the system development was how to fit the system into the triage workflow as smoothly as possible. This system can support comprehensive triage under a well-structured data system and the triage acuity guidelines. Our next step will be to thoroughly evaluate the practical effectiveness of the system.
