本專案是探討「人工膝關節置換術」和「人工髖關節置換術」臨床路徑之實施，對縮短患者住院天數、降低醫療費用、提高醫療品質、及病患滿意度之影響。專案在北部一家醫學中心之骨科病房進行，實施過程包括準備期、執行期、及評值期。共收案人工膝關節置換術187人，人工髖關節置換術64人。結果顯示，實施臨床路徑後病患住院天數顯著縮短，醫療費用比實施臨床路徑前降低，同時亦獲得相當好的醫療品質及病患滿意度。

　　　　　The purpose of this project was to explore the effectiveness of clinical path methods for total knee and total hip replacement patients. Patient's length of stay, medical cost, quality of care, and patient satisfaction were evaluated. It was performed in a medical center's orthopedic units in Taipei, Taiwan. The process included preparation, implementation, and evaluation phases. The total sample size for total knee replacement was 187, and 64 for total hip replacement. The results showed that the patient's length of stay was significantly reduced, average charges were decreased, and quality of patient care was maintained. Patients were highly satisfied with these clinical path methods.
