Platelet transfusions are a cornerstone of hemorrhage management in patients with thrombocytopenia or platelet dysfunction, yet their indications and dosing are largely based on expert opinion and low-quality evidence. This review offers a timely and comprehensive analysis of platelet transfusion practices in the United States (U.S.), uniquely integrating clinical evidence, such as the pivotal PLADO trial, with emerging technological advancements. Using a holistic approach, this manuscript addresses not only conventional practices (such as dosing standards and storage methods), but also cutting-edge alternatives like cold-stored and freeze-dried platelets, pathogen reduction technologies, and synthetic platelet substitutes. By juxtaposing U.S. practices with international standards, it highlights inefficiencies in dosing and supply management, proposing actionable solutions like lower-dose transfusions and diversified platelet inventories. Furthermore, the manuscript’s exploration of whole blood-derived platelets and the ethical debate surrounding paid donors adds a forward-looking perspective. By examining these innovations alongside strategies to optimize supply, this work aims to provide a comprehensive overview of how transfusion medicine is adapting to meet clinical and logistical demands.
