簡訊技術最早是在1991年開始應用於歐洲GSM系統，經過多年運用以後，目前己經是手機服務中最受到歡迎的項目；隨著行動科技的進步，除了提供單純個人對個人的文字訊息傳播之外，更被廣泛用來對於群體的訊息廣播。在2006年，某區域教學醫院引進某行動通訊系統，除了做群組內免費無線通訊；更用來做各種院內訊息廣播或各種醫療異常警示數值的即時通報系統。本研究以問卷方式，統計並探討全院醫師對院內行動通訊系統使用的滿意度，以期瞭解系統上線之效益，找出系統可改進之處。我們發現未經篩選、重覆傳送的簡訊，已經造成手機使用者的困擾，使得原來的正面效果逐漸降低，甚至造成了資訊超載或任務中斷而影響臨床決策的品質。我們提出運用以角色為依據的存取控制，並輔助以常規和緊急的發送時間控制，並做系統整合，利用分群、分組的方式來做簡訊接收端的篩選方式，運用以使用者為中心的思考設計模式，來提升系統功效和減少系統干擾，以提高醫療決策的正確度和敏捷度。我們也提供研究結論給系統商，甚至發展成另一套商品，做為其他和醫療作業有著相類似，對工作專心程度要求較高的企案，在採用行動簡訊系統時的參考。
The mobile-short-message technology was applied in the European GSM system in 1991 for the first time. It is the most popular service of the mobile-phone industry. The technology is not restricted to person-to-person communication, and its capacity to broadcast to a group of people enables many applications. In 2006, a mobile communi-cation system was introduced in the regional teaching hospital. Staffs can then get free wireless communication. Moreover administrative announcements are broadcast to re-levant groups and physicians are informed with abnormal medical events with the sys-tem. In this study, by using the questionnaire, we try to find the satisfaction level of these physician-staffs. We find that repeated short-message transmission without appro-priate filtering has not only made the handset users puzzled, but also caused the gradu-ate declination of positive effects. We also observed that information overload and sub-sequently task interruption caused the determination of clinical decision making quality. Herein, we represent the satisfaction, puzzle and the mitigation of this system.
