摘要

目的：本研究係以DeLone and McLean資訊系統成功模型(DeLone and McLean 1992; DeLone and McLean, 2003)爲理論基礎，經過理論探討，納入主管支持與使用者涉入，提出醫療資訊系統成功模型(Health Information Systems Success Model)。
方法：本研究針對東部某醫學中心與北部某教學醫院使用醫療資訊系統之員工，採立意抽樣方式共303份有效問卷，並使用敘述性統計、相關分析、驗證性因素分析與結構方程模式等統計方法進行模型之驗證。結果：(1)本研究所提出之醫療資訊系統成功模型與實徵資料檢測之後，證實在兩所醫院的環境脈絡下，具有相當良好之模型契合度，顯示本模型具實務臨床應用之潛力；(2)主管支持與使用者涉入，確爲影響醫療資訊系統三種品質（系統品質、資訊品質、服務品質）之重要直接前因變項，尤以主管支持對三者的影響力最大；(3)資訊部門的服務品質是主管支持、使用者涉入與系統使用、使用者滿意、系統淨效益之間的重要中介變項；(4)資訊部門的服務品質對於HIS的系統品質與資訊品質的提升具有顯著的正向影響；(5)根據路徑係數之總效果之分析，相較於其他的因素而言，主管支持是對於系統淨效益最具影響力的前因變項。
結論：醫療資訊系統成功與否，是需要多面向的評量。優質的資訊系統，需要甚多成本、人力及財力等資源的投入，醫療院所的經營者除了重現系統層面的因素（系統品質、資訊品質）之外，更不能遺忘社會層面的因素（主管支持、使用者涉入），以及技術層面的因素（服務品質），三者共生共存的重要性，如此方能在提升系統使用與使用者滿意的同時，讓系統的淨效益持續增進。

Objectives: Based on DeLone and McLean IS Success Model (DeLone and McLean, 1992; DeLone and McLean, 2003), the research integrates supervisor support and user involvement into the model to develop the success model of Health Information Systems (HIS Success Model).
Methods: The samples collected from two regional hospitals in Taiwan (separated in North, and East area of Taiwan). The visit questionnaires were completed by 303 employees known to be eligible and data were analyzed by descriptive statistics, correlation analysis, confirmatory factor analysis and Structural Equation Modeling (SEM).
Results: (1) According to the statistical results, the proposed model fits very well for the samples of two hospitals; (2) Supervisor support and user involvement, are indeed the important antecedents of system quality, information quality and service quality. Supervisor support is more important than user involvement. (3) The effects of supervisor support and user involvement on system usage, user satisfaction and net benefit are mediated by service quality. (4) Service quality of IS departments has positive significant influences on system quality and information quality. (5) According to the comparison of path coefficients, supervisor support has the most influence on net benefit.
Conclusions: The implications of this research can provide the managers of the hospital in Taiwan is that we must focus on not only the information system quality aspect (system quality, information quality), but also on the social interaction aspect (supervisor support, user involvement) and technical support aspect (service quality), so that we may expect system usage, user satisfaction and net benefit to increase simultaneously.
