使用者自建模式型醫院救護車派車輔助系統之開發與評估

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.
