药品库存周转率算法的解决方案

Solution of Algorithm on Turnover Rate of Drug Stock

目的:探讨药品库存周转率的算法。方法:根据商业领域库存周转率的计算方法并按照国家卫生计生委三级医院评审的明确要求,推导药品库存周转率算法,并编写相应程序进行验证。结果:按照商业领域库存周转率的算法,只能得到当天的周转率,若将上期销售情况换成本期销售情况则可统计任意时间的周转率,但部分品种的结果与实际差异较大,如采用统计留库时间的办法则可避免。结论:统计药品留库时间能更准确地计算除当天以外任意时间的库存周转率,且可以编程实现自动统计,并且同时可得到满足检查要求的品种占比。

Objective： To establish an algorithm on the turnover ratio of drug inventory. Methods： According to the employed method in the commercial field on calculating the inventory turnover and the requirements in the review of three level hospitals by the National Health and Family Planning Commission, an appropriate method for calculating the turnover rate of drug inventory was deduced. Meanwhile, a corresponding program was performed for the verification. Results： Only the day turnover could be obtained according to the algorithms on the inventory turnover in commercial field, and the circumstances of the sales could be replaced by the current sales to obtain the statistics at any given time, while there was remarkable difference between the calculated results and the actual results of some species. If the time in store was chosen as the statistical index, the problem could be avoided. Conclusion： The method with drug storage time as the statistical index can calculate the inventory turnover ratio at any time precisely, which also can be programmed automatically, and the proportion of available varieties meets the inspection requirements.
