摘要

目的：救護車的派遣管理工作同時影響民眾與醫護人員的權益。目前國外相關管理輔助管理系統的成果相當不錯，但國內醫院則明顯不足。本研究的目的便在以「使用者自建模式」策略，嘗試在資訊資源有限下自行開發輔助系統，並進行第一線人員對系統之接受度評估。
方法：研究個案醫院為台北市某醫學中心，救護車出勤量每月平均約418車次。使用Excel VBA 2003為開發工具，並採用「雛型法」開發。系統需求與功能設計以流程失誤點分析為主。系統功能架構分申請派車、派車核可、轉運紀錄、作業管理及系統維護五部份。評估採便利取樣，共計31位單位同仁，並使用「科技接受度模式」評估使用者對於系統之知覺易用性與有用性。
結果：評估結果顯示到試者普遍認為本系統之易用性及可用性皆相當高，同時系統直接效益將原本派車及轉運紀錄人工表單作業的三十分鐘減少到五分鐘以內即可完成。
結論：研究結果達到輔助解決救護車派車作業需求，並實證「使用者自建模式」之系統開發策略，在目前醫院普遍缺乏資訊開發資源情況下，可解決醫院部份行政管理自動化之需求。

Objectives: The quality of dispatching management for the ambulance in hospitals could significantly affect both patients and healthcare professionals. There are some related support systems abroad but no significant one has been developed and reported in Taiwan. The objectives of this study were to develop such an ambulance dispatching support system by the End-User-Computing strategy and to evaluate users' acceptance of the system.
Methods: The study was done in a medical center in Taipei. The average dispatching calls per month were 418. The system was coded with Excel VBA and developed by the prototyping approach. The analysis of fail points in the process was done to assure the need requirements and to design the system functions which were the Dispatching Request, Dispatching Approval, Transportation Recording, Operation Management and System Maintenance. 31 subjects were invited at their convenience for the evaluation. The Technology Acceptance Model was used to assess subjects' perceived ease of use and usefulness of the system.
Results: The results indicated users' high acceptance of the system in terms of ease of use and usefulness indicators. The system also decreased the dispatching and recording time from 30 to 5 minutes. The system was capable of supporting a quality ambulance dispatching task.
Conclusions: The strategy of ”End-user Computing” appeared a very valuable solution for hospital workers, who could not get enough organizational IT support, to partly resolve the automation insufficiency.
