醫院藥品訂購政策之研究:在供給及需求不確定下

Hospital Medication Reorder Policy Under Demand and Supply Uncertainties

摘要


全球性藥品短缺與臨床藥品需求的問題,使得醫療管理者難以做出正確決策。本研究同時考量藥品供給以及需求的不確定性,建構藥品訂購政策的模式,以維持適當存貨成本,並得以減少藥品缺貨問題的發生。以5項指標將藥品進行ABC分類,發展各分類藥品之訂購模型。實際資料分析發現,5項指標均可使缺貨天數大幅下降85%至90%;總存貨成本則微幅變化,介於-0.7%至5.7%,因此本研究的訂購政策可有效因應難以預測的缺藥風險,增進藥品存貨管理效益。

The global pharmaceutical drug shortage and the uncertain clinical demand make it difficult for medical managers to make the right decisions. This study simultaneously considers the uncertainties of drug supply and demand, and develops a reorder model for hospital medication to maintain proper inventory costs and reduce the occurrence of drug shortages. Based on five indicators, this study classifies medicines using ABC classification, and develops a reorder model for each category of medicines. The analysis of actual data found that all five indicators can significantly reduce the number of out-of-stock days by 85% to 90%; the total inventory cost slightly varies between -0.7% to 5.7%. Therefore, the proposed reorder policy can effectively deal with the unpredictable shortage risk and improve the medication inventory management.
