隨著醫療環境不斷變化，醫院如何在日趨激烈的競爭環境中生存已成為企業關注的議題。本研究面臨檢查室檢查項目內容繁雜，且排程檢查時段規則多且複雜，常導致病人因檢查等候時間過長，造成病人焦急。本研究主要目的係探討個案T醫院現行檢查流程，從中找出不必要繁雜作業，以優化檢查作業流程，縮短檢查時間。為達到改善檢查流程之研究目的，本研究採取精實六標準差方法，導入國、內外精實生產系統概念，以審視檢查流程系統中產生不必要的浪費，運用精實生產之「暢流」為首要，優化檢查流暢度、有效縮短檢查等候及降低成本，以提升檢查室檢查流程效率，並擬定出改善流程。研究結果發現，從改善前的240分鐘，降低為改善後167分鐘，大幅降低73分鐘；神經傳導檢查與頸動脈超音波檢查，神經傳導檢查由原先40分鐘，降低為20分鐘；頸動脈檢查由原先35分鐘，縮短為20分鐘，本研究之檢查流程運用精實概念，有效減少檢查流程的不必要浪費，明顯降低檢查流程時間，相關的改善成果提供後續醫院及學術界參考。

With the continuous change of the medical environment, how to survive in an increasingly competitive environment has become a topic of concern for enterprises. The contents of the inspection room inspection project are complicated, and the rules of the schedule inspection period are numerous and complicated, which often leads to the patient waiting for too long, which causes the patient to be anxious. The purpose of this study is to explore the current inspection process of Case T Hospital, to find out unnecessarily complicated operations, to optimize the inspection process and shorten the inspection time. In order to achieve the purpose of improving the inspection process, this study adopts a six-standard method to introduce the concept of a lean production system and reduce the waste of the process. In this paper, we use the ＂smooth flow＂ of precision production as the primary task, optimize inspection fluency, effectively shorten inspection waiting and reduce costs, improve the efficiency of inspection room inspection process, and formulate improvement process. The results revealed the inspection process was reduced from 240 minutes before improvement to 167 minutes after improvement, with a total reduction of 73 minutes. Nerve conduction examination and carotid ultrasound examination, nerve conduction examination from the original 40 minutes, reduced to 20 minutes. The carotid examination was shortened from the original 35 minutes to 20 minutes. The inspection process uses lean thinking to effectively reduce the waste of the inspection process and reduce the inspection process time. Finally, the paper provides relevant improvement results for reference by hospitals and academic circles.
