21世紀為「知識經濟」世代,若能有效掌握知識,並創造最大價值,即是最大贏家。在現今時代脈絡下,知識管理被視為企業組織提高生產力及績效,並且維持企業本身在同業間的競爭力與生存優勢之關鍵要素。醫療健康照護一直以來皆屬於知識密集產業的一環。醫護人員的工作旨在促進人們的健康福祉,工作內容往往涉及高度專業之醫學知識與技術。因此,近幾年來,許多醫療體系開始思索如何有效管理組織內部之知識的流通、整合及創造,以提升整體醫療品質及增進醫療體系本身的競爭力,因此紛紛購入或建置知識管理系統,推導組織內部之知識管理活動。 針對上述情況,本研究旨在於探討影響醫療體系員工使用知識管理系統之因素,並以台灣某南部區域型醫療院所之護理人員為研究對象。在研究架構部份,主要以「接受後資訊系統持續使用模式」為脈絡,關注資訊科技使用後的決策行為,並以「系統品質」、「訊息品質」、「組織影響」、「個人差異」等構面,檢視其與系統的「認知有用性」及「任務科技配適度認知」之關聯性。另外,亦檢視系統的「任務科技配適度認知」與「認知有用性」兩認知構面之關聯性,並進一步評估這兩項認知構面與「知識管理系統使用」之關聯性。 本研究主要以問卷調查法進行資料蒐集,共回收有效問卷393份,並以SPSS 12.0及AMOS 5.0進行信效度分析、描述性統計分析與結構方程式之適配度檢定。針對研究假設未獲得支持的部份,則另以深度訪談法進行資料蒐集,以獲得問卷調查以外更深入、貼近事實之資料。本研究主要結果為: 一、 電腦自我效能-他人指導操作、系統品質、訊息品質與知識管理系統之任務科技配適度認知呈正相關。 二、 電腦自我效能-自行操作與知識管理系統之任務科技配適度認知呈負相關。 三、 獎勵機制、系統品質、訊息品質與知識管理系統之認知有用性呈正相關。 四、 任務科技配適度認知會正向影響認知有用性。 五、 認知有用性會正向影響知識管理系統之使用;任務科技配適度認知與知識管理系統使用之關聯性則無法獲得支持。
The 21 century is a generation of knowledge economy. The one who can master knowledge and use it to create the most value is the biggest winner. During this generation, knowledge management is seen to be the key factor for an enterprise to enhance the productivity, performance and competitiveness between the same trade. The healthcare industy is always belong to the knowledge-intensive industry. Healthcare workers aimed at promoting people's health and well-being, so their jobs often involve a high degree of professional medical knowledge and techniques. In recent years, many healthcare industries began to think about how to effectively manage the flow, integration and creation of knowledge within the organization in order to improve the overall quality and the competitiveness of the healthcare system itself, so they began to purchase or set up their own knowledge management system to implement the knowledge management activities within the organization. The purpose of this research is to explore the factors affecting the healthcare system employees to use knowledge management system, and the objects of study are nursing staffs of one regional hospital of southern Taiwan. In the research framework, we use “understanding information systems continuance: An expectation -confirmation model”to understand the decision-making behavior after using the information technology. Then, we apply “system quality”, “information quality”, “organizational influences”, “individual differences”to test the relation to“the cognition of task-technology fit”and “perceived usefulness”of the system. In addition, we also test the correlation between “the cognition of task-technology fit”and “perceived usefulness”. Finally, we evaluate the correlation between “the cognition of task-technology fit”, and “the use of knowledge management system”as well as “perceived usefulness” and “the use of knowledge management system”. In this study, we execute a survey to collect 393 efficient questionnaires, and apply the analyses of reliability , validity, descriptive statistics and goodness-of-fit indices by using SPSS12.0 and AMOS 5.0. For the research hypotheses that are not supported, we apply depth interview to collect more in-depth data. The results in this study: 1.Computer self-efficacy(others’ guide and operate), system quality and information quality positively influence the cognition of task-technology fit. 2.Computer self-efficacy(operate by their own) negtively influence the cognition of task-technology fit. 3.Incentives, system quality and information quality positively influence the perceived usefulness of knowledge management system. 4.The cognition of task-technology fit positively influences the perceived usefulness of knowledge management system. 5.Perceived usefulness of knowledge management system positively influences the use of knowledge management system. The association between the cognition of task-technology fit and the use of knowledge management system can’t be supported.
