摘要

許多文獻指出，醫療衛材的成本占了醫院的總營運成本約30%至40%，因此醫療衛材的存貨管理扮演了一個重要的角色。本研究針對國軍桃園總醫院手術室的醫療衛材之存貨管理來做研究。我們實際到手術房收集並觀察2012年九月份到2013年十二月份所使用的衛材及其存貨管理情形，期間一共約100天在現場。然而，一般業界所使用的存貨管理理論較難應用於醫療界，因為手術室所使用的衛材常常會有特殊的需求情況發生。因此，大部分有關於存貨管理的量化分析不能夠有效地管理醫療衛材。根據以上問題，本研究會發展出一個特別適合國軍桃園總醫院手術室衛材的存貨管理方式，且能夠讓衛材管理員易於了解、容易使用。本研究分成兩個階段，第一階段使用群集分析將所有衛材依照本身會影響需求的特徵進行分類。第二階段找出各組別最適合的需求預測計算出各衛材之預測值，並結合存貨政策，最後，本研究會實際到國軍桃園總醫院手術室利用此改善方式進行模擬評估。評估結果本研究能夠有效降低25%的存貨成本，並且是在沒有任何衛材缺貨的情況下。

According to a number of researches, the survey found that the average cost of medical materials accounts for about 30% to 40% of the total operating costs. Therefore, the management of medical materials plays a crucial role in hospitals. This research focuses on inventory management in operation room of Taoyuan Armed Forces General Hospital (TYAFGH). We went to the hospital intermittently (September, 2012 - December, 2013) for 100 days to observe the inventory management process and collect data of the operation rooms.
However, the inventory management theory of business and industrial fields apply to the medical field is difficult. While managing the materials used in operation room, a few special demand will emerge. Therefore, most of the quantitative classification cannot classify them effectively. From what’s discussed above, this research will develop material management model specifically for TYAFGH’s operation room. This model will be simple-to-understand and easy-to-use to assist material administrator to reduce material cost by an average of 25% while still keep the healthcare service quality. This research has two steps, first step is that classification is based on characteristic of operation room materials, and the second step is to make demand forecasts for each classification, and propose the inventory policy. Finally, we will go to TYAFGH and apply the inventory management improvements step of this research to conduct simulated assessment. The contribution of the research is that effectively reduce 25% inventory cost without any material out of stock.
