**4. Conclusions**

Blood demand has increased worldwide; however, blood supply is insufficient to meet this need. Therefore, the proper management of blood supply and blood demand is crucial to avoid sudden blood shortages. The latter can result in the failure of BTS, national health insecurity and consequently, international health insecurity. Health insecurity ultimately leads to societal and political insecurity, so health security issues remain the priority in terms of national security. The perception of health difficulties through the global health security framework leads to international health securitisation, attracting the attention and support of governments, and pressuring decision-makers to act early. Evidence-based plans for blood safety and availability should be developed, implemented and updated regularly. Global health policies and international health regulations related to BTS should be ready to respond quickly to any challenges in delivering an adequate supply of safe blood, especially during disasters and emergencies. It is essential to implement guidelines and strategies that concern the management of blood supply and blood demand, particularly before any anticipated catastrophe or crisis, to avoid sudden blood shortages. The most essential and efficient method for managing blood inventory is PBM. The implementation of PBM not only reduces the chance of a blood shortage, but is also associated with a low risk

of blood transfusion complications, reduced hospital stays and healthcare costs, and most importantly, lower morbidity and mortality. The information provided by this chapter is linked to the management of blood supply and blood demand as an essential component of global health security. It helps in planning for the proper management of blood inventory and ensuring the availability of safe blood and blood components to avoid sudden blood shortages and the serious consequences of such shortages.
