Method for managing stocks of donated blood components

The object of the study is the system for managing blood component stocks, which allows, taking into account the need for blood components in healthcare institutions, possible volumes of procurement and stocks of blood components in the blood center and in other healthcare institutions, to distribute and redistribute blood components among healthcare institutions. The purpose of developing a method for managing the stock of donated blood components is to optimize the distribution and issuance of stocks of blood components to healthcare facilities by the blood center with the possibility of redirecting blood components between healthcare facilities. To solve the problem, methods of product inventory management, methods of inventory optimality assessment, methods of calculating blood component inventories in the blood center, methods of calculating the need for blood components from healthcare institutions were used. A formalized description of the mechanism for managing blood component inventories in the blood center is proposed, the stages of the method for managing blood component inventories in the blood center are presented, which can be applied in the development of the functionality of the blood component inventory management module of the blood service medical information system. The results of the study can be applied to solve the problems of optimal distribution of blood components among healthcare institutions, taking into account their weekly, monthly, and annual needs. This, in turn, will allow to fully provide health care institutions with the necessary donor blood components, to predict the optimal volumes of procurement of donor blood components for each blood group and Rh factor, to rationally plan the purchase of consumables for the procurement of donor blood components and to minimize the number of write-offs of donor blood components in the blood center and health care institutions due to the expiration date.
