近年來政府為提供持續性的醫療照護，加速病人診療決策，提昇醫療服務品質，減 少醫療資源浪費，己積極推動跨院電子病歷交換系統的建置，並透過相關的措施與作法 以提升各醫療院所上傳電子病歷資料之意願。然而，目前醫師在跨院電子病歷整體的使 用率上，仍有很大改善空間。由於醫師是病患醫療服務的主要提供者以及決策者，以及 電子病歷交換系統的主要使用者，因此其對於國內跨院電子病歷交換的推動扮演關鍵角 色。本研究將以現狀偏誤觀點作為理論基礎，以此瞭解影響醫師抗拒使用跨院電子病歷 系統之關鍵因素，並探討相關因素對於醫師抗拒電子病歷交換系統使用的影響。並採用 問卷調查法針對國內目前已通過電子病歷交換互通查驗醫院之醫師進行資料蒐集(滾雪 球抽樣方法)，所蒐集資料再以最小平方法(PLS)之結構方程模型統計工具進行分析。藉 由本研究的進行將能發展出一個適用於評估醫師抗拒使用電子病歷交換的重要衡量工 具，透過此工具將能深入瞭解醫師為何會對電子病歷交換產生抗拒及形成過程。醫療機 構與衛生主管機關將可針對本研究所發現之關鍵因素，採取適當的策略與措施以減輕使 用者抗拒，並加速跨院電子病歷交換的發展。 Recently, the government of Taiwan has put much effort in promoting the use of cross-hospital exchange of electronic medical records in order to achieve the continuum of care, facilitate clinical decision making, improve quality of care, and reduce the unnecessary waste of limited medical resources. However, only limited data of the exchanged electronic medical records are used by physicians so far. Physicians are the key service providers and decision maker in providing medical services. In addition, they are the major users of the cross-hospital exchange system of electronic medical records. Thus, physicians play central roles in the further promotion of exchange of electronic medical records. The purpose of this study is to understand the key factors influencing physicians’ resistance toward cross-hospital exchange system of electronic medical records based on a status quo bias perspective, which is proposed to understand the influencing processes of user resistance. The survey methodology will be conducted for validating the proposed research model. The respondents of this study are physicians of the hospitals that have been certified to support cross-hospital exchange of electronic medical records. By using the snowball sampling strategy, the data collected from the survey will be analyzed through partial least square statistical analysis technique. Therefore, the result of this study will provide an adequate measurement tool for understanding the reasons influencing physicians’ resistance toward cross-hospital exchange system of electronic medical records. Thus, Taiwan government and healthcare industry could make appropriate incentives for mitigating the issues of physicians’ resistance in order to promote the development of cross-hospital exchange of electronic medical records in Taiwan.
