全民健保實施後,面臨醫療費用不斷上漲的壓力。健保局為了提升管理效率與合理分配醫療資源,在2010年宣佈將全面實行診斷關聯群(TW-DRGs),依據疾病的國際分類碼(International Classification of Diseases, ICD)之主診斷碼、次診斷碼、病人年齡、有無合併症或併發症等分類分到一個DRG碼。並將此編碼當成為醫療費用給付的主要依據。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,以方便需要時之查詢或使用。研究顯示,有些醫院藉由不正確的技巧,改變診斷關聯群的編碼以獲取較高的給付。不正確的內容包含了主次診斷錯置(Resequencing)、編碼錯誤(Miscoding)、主要診斷錯誤等。其中DRGs編碼錯誤率可能超過10 %,因此醫護人員使用DRG資訊系統時應該更加小心謹慎,若編碼不佳甚至產生錯誤,其後果必定會影響醫院的財務收入。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。 故本研究採用IS接受後持續使用模式為基礎,並且補充相關文獻延伸相關構面,結合計畫行為理論與科技接受模式,來探討醫師對於DRG資訊系統期望與使用後影響使用者滿意度的因素,提出本研究架構並且加以實際驗證,希望可以作為學術上與實務上的參考。
This research is designed to explore the acceptance behavior and satisfaction with the post implementation of Diagnosis Related Groups Information System (DRG-IS) at medical centers in Taiwan. The TW-DRG based upon coding systems which originated from International Classification of Disease 9 version (ICD-9) is a payment system for the main purpose of healthcare cost containment under the National Health Insurance Plan. From several comprehensive researches indicated that the implementation of DRG-IS might cause may serious errors in clinical practice such as “resequencing” and “miscoding”. Those wrongful events eventually will impact seriously to management outcome and physician acceptance behavior. The research is thus based on the A Post-Acceptance Model of IS Continuance and other critical literature review trying to establish a conceptual framework and study the acceptance behavior and satisfaction at medical centers in Taiwan. The main purpose is going to find out a solid evaluation and prediction model for the DRG-IS in Taiwan.
