A Computer Based System for Optimal Blood Inventory Control
In the ideal blood bank there should be no outdating and no shortage of blood. Without taking special actions, however, it is impossible to achieve that state in any blood bank. Recycling of blood units from hospitals with high percentages of outdating to hospitals with many transfusions is an accepted and effective method of reducing out- dating. Several descriptions of computer based systems for redistribution between blood banks have been published (ref 1, ref 2). In the last few years rapid progress in blood banking has been made, e. g. new ways of storing red cells (SAGMAN — saline suspended red cells without plasma, extended storage time, (ref 3)), and new techniques in pre- transfusion testing (type and screen — no direct test donor/recipient, (ref 4)). Computers for supporting laboratory management and for storing laboratory information have been introduced in an increasing number of blood banks. These new techniques have created new possibilities for inventory management. By means of computer simulations we have studied the effects of adopting these new techniques in blood banking, including local blood inventory optimization and planning the drawing of blood. Based on experience from computer simulations, a computer based system for optimal blood inventory control has been developed.
