Optimum Inventory at Wards Using : An Injection Order System

In preparing for sudden changes in patients' conditions and emergency visits after office hours, certain amounts of injections should be kept in stock. To optimize the stock of injections at wards, we analyzed the data of injection usage at wards obtained by the injection order system. We found that the amounts of inventory at wards could be well described by an exponential function. Based on these results, we formulated equations with which we can determine optimum inventory of injections at each ward. Using these equations, it is possible to reduce the number of expired injections, and the work of inventory managing staff.
