2011 年7 月美國食品藥物管理局通過修法,批准醫師使用手持行動裝置替病人看診與調閱病人的病歷,台灣衛生署也在2013 年提出了健康雲計畫,而目前台灣也已經有十多家醫院著手建置專為行動裝置設計的系統,因此對醫師來說使用行動裝置的意圖為何,將會是系統建置的一大重點。本研究以DeLone and McLean(1992)所提出的資訊系統成功模式為基礎,並加入Clarke(2001)提出的行動科技所擁有的無所不在、地點性、個人化和便利性四大特性,去檢測本研究所提出的假說是否成立。本研究針對目前已有建置行動醫療APP 系統的醫院進行問卷發放,共收集到180 份有效問卷,有效回收率為60%,並以統計軟體SPSS 22.0 與Smart PLS 2.0 去驗證變數間的關係。研究結果發現在眾多因素當中,行動醫療APP 的滿意度會對行動醫療APP 的使用意圖帶來最強烈的影響。 In July 2011, the US Food and Drug Administration amended the law and approved the use of a handheld mobile device for the visit and access to medical records. The Department of Health in Taiwan in 2013 also proposed a Health Cloud Plan, and currently there are more than a dozen hospitals starting to build mobile hospital system. Taiwan’s medical institutions are embracing the advent of the mobile device, and physicians who use mobile device for intended purpose will play a major role in the success of this new system. This study aims to design a model of the factors which affect the user’s intention of Medical Mobile Application. The proposed model are jointly based on the theory of Information System Success model and Clarke’s theory of four value proposition dimensions, namely, ubiquity, personalization, localization and convenience, to measure the quality.In this study, uestionnaires were distributed to hospitals. A total of 300 questionnaires were administered to physicians and 180 completed the questionnaires. We use SPSS 22.0 and SmartPLS 2.0 statistical software for data analysis. The results show that the key factor affecting the user’s intention is the user’s degree of satisfaction. If users are satisfied with the Medical Mobile Application, they will increase their intention to use this new device.
