以TAM模式探討醫院電子公文系統使用者接受程度－－以北部某地區教學醫院為例

The Study of User’s Acceptence of Hospital Electronic Document System Based on the Technology Acceptance Mode

醫院公文處理長久以來皆採紙本逐級簽核方式，易造成公文旅行、遺失等耗費時日為人詬病之問題，期望透過電子公文的導入，能提升行政作業效率，但導入一個創新的資訊作業系統，並非單純改變現有作業環境即可，組織成員的接受度恐亦需同時配合改變，方能發揮事半功倍之效，故本研究以Davis (1989)之科技接受模式 （Technology Acceptance Mode, TAM）為理論基礎，對北部某地區教學醫院員工進行實證調查，以瞭解電子公文導入之接受程度，進而對於使用態度及持續使用意願之影響。本研究以北部某地區教學醫院之員工為研究對象，採立意抽樣，針對在院內有實際使用電子公文系統之員工進行問卷發放，總計發放151份問卷。回收有效問卷121份，有效問卷回收率約為80.13%。研究結果顯示主管對於系統認知的有用及易用程度皆高於非主管人員，且當使用者對於目前組織變革中公文行政管理的現況認知愈良好時，其知覺系統有用及易用程度會愈高。而使用者所知覺系統的有用及易用程度亦會透過使用態度而影響持續使用意願。故未來醫療院所導入資訊化作業時，應特別考量員工對於組織變革的接受或抗拒程度及系統有用與易用性這兩個因素，以達資訊科技投資之效益，提昇醫院整體的經營管理效能。

The official document in a hospital system has been preceded by paper works in cascade order, as well as it results in document-traveling, time-wasting, and missing issues. By the introduction of electronic document system, the improvement of the administrative efficiency is expected. In order to maximize the effectiveness with less effort, not only do we have to alter the present operative environment, but also the acceptance of members in the organization. According to Davis’ (1989) “Technology Acceptance Model” which had researched on employees of a district teaching hospital in Northern Taiwan, the study is to investigate the acceptance of the computerized information management, and the influence on the attitude and inclination for continuous usage. This study regards the employees in a district teaching hospital in Northern Taiwan as the subjects through purposive sampling. The subjects being the de facto user of the electronic document system, a total of 151 copies of questionnaire were provided, 121 copies were retrieved. The validated retrieval rate is 80.13%. The result shows that the managing staff has higher perceived usefulness and perceived ease of use than the non-managerial staff does. The better the user could cognize the present status of the organizational change in processing document, the higher the level of perceived usefulness and perceived ease of use of the system could be. Moreover, the user’s attitude toward this perceived system will alter the inclination to continuous usage. Therefore, in the future, when the hospital authority introduces new informational operating system, there are two aspects should be taken into account, namely: level of acceptance or defiance for organizational change and the perceived usefulness and perceived ease of use of the system. Overall, the investment in informational technology will increase efficiency of operational management as well as benefit of hospital.
