From demand forecasting to inventory ordering decisions for red blood cells through integrating machine learning, statistical modeling, and inventory optimization

Abstract: Background: The demand and supply of blood are highly variable over time.Blood inventory management that relies heavily on experience-based decisions may not be adaptive to real demand, leading to high operational costs, wastage, and shortages. Methods:We combined statistical modeling, machine learning, and optimization methods to develop a data-driven demand forecasting and inventory management strategy for red blood cells (RBCs). We then used the strategy to inform daily blood orders. A secondary semi-weekly… Show more

“…The log‐normal model slightly outperformed the normal model as well, although with the caveat that both informed models resulted in higher total RBC inventory which could potentially contribute to wastage. More sophisticated demand forecasting models could potentially reduce ordering frequency while limiting wastage 30 …”

“…More sophisticated demand forecasting models could potentially reduce ordering frequency while limiting wastage. 30 Limitations of this study include the lumping together of all RBC transfusions regardless of ABO or RhD type for a broader analysis. In addition, the measure of individual patient daily RBC usage is less applicable to research centered on total RBC usage during a patient's encounter, although it informs daily hospital RBC usage more directly.…”

“…With the advent of very large‐scale computational power (super computers, massively parallel processing, and cloud‐based analytics) and connected, interoperable healthcare data pipelines, there is the promise of data‐driven in‐silico scientific insights stemming from use of AI/ML in transfusion medicine research. Applications include blood demand forecasting and predicting transfusion requirements 61–63 . Techniques using ensemble and federated methods are relatively new to the field of transfusion medicine and merit focused investigation to define applicability to a range of transfusion research questions.…”

“…Inventory management of blood products has received considerable attention from both the Operations Research [2][3][4][5][6][7][8] and Transfusion Medicine [9][10][11] literatures. Despite the large literature, the use of these methods in practice has been limited.…”
