The ultimate goal of a hospital blood bank inventory control programs is to reduce wastage of blood products and unnecessary use of laboratory services without jeopardizing patient safety. The development of a practical blood ordering policy at the hospital level is an integral part of any such program. In order to explore various blood ordering options in detail, a computer simulation of a hospital blood inventory was used to assess the impact on blood band performance measures of reductions in group O and non-group-O levels from baseline levels, assuming both a 21-day and 35-day shelf life. On the basis of data derived from this study showing that such inventory reductions accompanied by partial protection of the group O inventory will not result in significant shortages, a practical strategy was developed for establishing optimal target inventory levels for a hospital on an empirical basis. These target levels can serve as a guide for subsequent blood ordering. A step-by-step approach for analyzing a hospital blood inventory control program is then suggested, accompanied by an action plan for implementing change which incorporates the experimentally-derived blood ordering strategy. Adherence to this plan should result in a low outdate rate, a reduction in unnecessary cross-matching, and greater availability of blood for those patients with a legitimate need for it.
医院血库库存控制项目的最终目标是减少血液制品的浪费以及实验室服务的不必要使用，同时不危及患者安全。制定医院层面切实可行的用血订购政策是此类项目不可或缺的一部分。为了详细探讨各种用血订购方案，利用医院血液库存的计算机模拟来评估，假设保质期分别为21天和35天，从基线水平降低O型血和非O型血库存对血库绩效指标的影响。基于本研究得出的数据表明，这种库存减少并伴有对O型血库存的部分保护不会导致严重短缺，在此基础上制定了一种实用策略，用于凭经验确定医院的最佳目标库存水平。这些目标水平可为后续用血订购提供指导。随后提出了一种逐步分析医院血库库存控制项目的方法，并附有一项实施变革的行动计划，其中纳入了通过实验得出的用血订购策略。遵守该计划应能降低过期率，减少不必要的交叉配血，并为有合理用血需求的患者提供更多血液。
