探討台灣診斷關聯群資訊系統之實證研究

Diagnosis Related Groups – Using Partial Hip Arthroplasty as An Example

全民健保實施後，面臨醫療費用不斷上漲的壓力。為了提升管理效率與合理分配醫療資源，在2010年宣布將全面實行診斷關聯群（TW-DRGs）。而DRG資訊系統可以將病人的疾病診斷及相關處置訊息予以編碼並加以整合，藉以產生統計性分類資料。因此，如何使用適當的DRG資訊系統，提供正確與完整的編碼，減少人為因素造成的錯誤，成了重要的關鍵。本研究以某醫學中心為研究對象，共發出200份問卷，有效問卷為106份，研究結果顯示，認知有用與認知易用是影響醫師使用DRG資訊系統滿意度的關鍵因素。故研究建議，在開發建置DRG資訊系統時，要能配合使用者之價值觀、經驗及需求；能及早提出有效因應措施及制度，以提高使用者的接受程度與滿意度。

Ever since the implementation of the NHI, we've been facing the pressure of rising health care costs. In order to improve management efficiency and obtain more rational allocation of medical resources, the Bureau announced in 2010 a program to introduce a systemic strategy called Diagnostic Related Groups (TW-DRGs). The DRG information system encompasses the patient's disease diagnosis and disposal of encoded and integrated messages to enable the production of statistical classification of data. Therefore, how to use the appropriate DRG information system to provide accurate and complete coding to reduce errors caused by human factors, has become a key issue. This study used a certain medical center as its subject, issued and distributed 200 copies of a questionnaire among the center's staff physicians. The number of returned, validly answered copies was 106. The results show that usefulness and ease of use of the system are the two key factors affect how those physicians perceive the DRG information system. Therefore, we recommend that development of the DRG information system should emphasize on meeting the user's values, experiences, and needs; and as soon as possible to respond effectively to measures and systems to improve user acceptance and satisfaction.
