摘要

隨著資訊科技在醫院的普遍應用，醫院管理者對於醫院高階主管資訊系統有著極高的興趣。目前國內醫療資訊系統(HIS)大多仍停留在輔助日常作業的應用上，其功能上不足以產生輔助高階主管在制定決策時所需的資訊。本研究利用資訊取得行為與心智模式的學習探討醫院高階主管使用醫院主管資訊系統之行為，以國內醫學中心為對象。隨機抽樣共計發放505份問卷，經回收後共計180份問卷，有效問卷160份，有效回收率為31.7%。在資料的處理上，採用SPSS 12.0及SmartPLS 2.0作為統計分析工具。其後透過結構方程模式驗證研究概念模型，期望提供醫院高階主管對於醫院主管資訊系統之有效使用。研究結果顯示，電腦自我效能會直接影響心智模式的建立；系統特性會直接影響學習型態與資訊取得行為；個別差異中，控制意念會直接影響審視掃描；組織因素中，工作特性非結構化會直接影響焦點搜尋，認知環境易變會直接影響審視掃描；資訊取得行為中，焦點搜尋會直接影響心智模式維護及認知效益，審視掃描則會直接影響心智模式建立；學習型態中，心智模式建立會直接影響認知效益，心智模式維護會直接影響認知效率及效益。

Existing health information systems largely only support the daily operations of a medical center, and are unable to generate the information required by executives for decision-making. In this environment, executives must consider not only the best application of information technology, but also how to use this information effectively. Building on past research concerning information retrieval behavior and learning through mental models, this study examines the use of information systems by hospital executives in medical centers. It uses a structural equation model to help find ways hospital executives might use information systems more effectively. There were 505 questionnaires administered and 160 effective respondents which resulted in the response rate of 31.7%. The results show that computer self-efficacy directly affects the maintenance of mental models, and that system characteristics directly impact learning styles and information retrieval behavior. Additionally, individual differences between executives and their locus of control impact the usefulness of scan-based information searches. Contextual factors and unstructured work characteristics also impact the usefulness of more focused information searches. Other results include the significant impact of perceived environmental uncertainty on scan searches; information retrieval behavior and focused searches on mental models and perceived efficiency; scan searches on mental model building; learning styles and model building on perceived efficiency; and finally the impact of mental model maintenance on perceived efficiency and effectiveness.
