目的:药品供应过程中尽可能地减少缺货,更好地保障临床供药。方法:通过汇总15周的缺货信息,提取药房缺货频次高的药品做药品库存、消耗-时间分析图,查找缺货原因,提出改进办法。结果:共涉及476品种,1 322品次,计算缺货率为3.14%,分析各种缺货原因。结论:通过制定应对措施,将药品缺货的产生降至最低,最大程度地保障临床药品供应。 Objective: To reduce out-of-stock as much as possible in the course of drug supply and to better ensure clinical drug supply. Methods: By summarizing the out-of-stock information for 15 weeks, the drugs with high out-of-stock frequency were extracted to make medicine inventory, consumption-time analysis chart, find out the reasons for out of stock, and put forward the improvement measures. Results: A total of 476 varieties and 1 322 products were involved, and the out-of-stock rate was calculated to be 3.14%. The reasons for various out-of-stock items were analyzed. Conclusion: Through the development of response measures, the production of out-of-stock drugs will be minimized to ensure the maximum supply of clinical medicines.
