Summary
Inventory management for platelet concentrates (PCs) was optimized using a theoretical approach, significantly reducing waste and extending shelf life. This data-driven method improved blood bank operations and reduced shortages.
Area of Science:
- Operations Research
- Blood Banking
- Inventory Management
Background:
- Platelet concentrates (PCs) have a short shelf life, leading to challenges with variable demand, shortages, and outdating.
- Current inventory management relies on experience-based rules, which are often suboptimal.
- There is a preference for younger PCs, necessitating strategies to extend their usable time (Time Till Outdating - TTO).
Purpose of the Study:
- To minimize outdating and shortages of platelet concentrates.
- To extend the Time Till Outdating (TTO) for platelet concentrates.
- To evaluate a theoretical approach for optimizing PC inventory management.
Main Methods:
- Implemented a combined approach of stochastic dynamic programming and simulation (SDP/S) techniques.
- Developed and utilized specialized software: thrombocyte inventory management optimizer (TIMO).
- Calculated an optimal order-up-to rule based on historical data and applied it to inventory management.
Main Results:
- Achieved a significant reduction in the median weekly outdating percentage to less than 1%.
- Increased the Time Till Outdating (TTO) by an average of 0.48 days.
- Gained personnel confidence in adopting the theoretical approach and TIMO software due to demonstrated improvements.
Conclusions:
- Theoretical approaches, like SDP/S, can substantially improve blood bank PC inventory management.
- The implemented system led to significant reductions in outdating and shortages.
- Adoption of the theoretical model resulted in more structured, less reactive inventory management.

01:18Structure and Function of Platelets
The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...

01:22Formation of the Platelet Plug
The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
