碩士 === 元智大學 === 資訊傳播學系 === 92 === The Physician Order Entry Systems (POES) have replaced the traditional handwritten prescription process and improve the efficiency of hospitals. However, medication errors may arise from poorly designed POES. While most researches of information technology in medication errors are focused on quality of medication services, system functions, evaluation of management performance and integration of electronic medical records, researches discussing preventing medication errors by interface design engineering of POES are rare. This dissertation surveys possible factors triggering medication errors of POES from the viewpoint of human-computer interface design. The following results are obtained: 1. The evaluation categories to evaluate the interface design of POES are deduced; 2. The factors causing medication errors derived from inadequate interface design of POES are analyzed by the data collected from the suggestions of users and usability experts; 3. Interface design principles constructing safer and more reliable POES’es are proposed; and 4. Suggestions of users and usability experts are compared to reveal the difference and conflicts to understand the key points in designing better POES’es.
