醫療資訊系統透過支援必要的醫院管理與醫療作業，協助提供高品質與高效率的病患照護。本研究提出一個結合可用性要素與問卷調查為基礎的方法，評估醫療從業人員對於所使用之醫療資訊系統的評價。其中包括動態重視度表現值分析法，分析使用者認知中對於可用性要素的滿意程度與期望程度。根據調查而得的資料，將受訪者對於系統可用性要素的認知各別以第三四分位數與第一四分位數區分為高重視度／高表現值與低重視度／低表現值。所提出方法實際應用於案例醫院提供之醫療行政服務的出院流程中。結果顯示所提方法具備在不同醫療作業環境中有效識別醫療資訊系統中需要改進的可用性要素，且能夠進一步提供醫療資訊系統設計時重要的使用者需求資訊。

Healthcare information system (HIS) contributes to a high-quality, efficient patient care by providing good supports to the administrative and medical tasks required. In this research, a questionnaire-based approach is proposed to evaluate the use of HIS in terms of usability factors. The perception of the satisfaction and expectation in these factors is then investigated using the generalized version of importance-performance analysis, or referred to as dynamic importance-performance analysis in this paper. Based on the survey data, the relative levels of ＂high importance/performance＂ and ＂low importance/performance＂ are dynamically distinguished by the 75th percentiles and 25th percentiles, respectively. The proposed methodology is demonstrated in a case study conducted for the discharge process in a hospital administration service. The analytical results presented in the case study provide insights in system design to further improve the usability of HIS under specific clinical environment.
