A recent study published in The Lancet Planetary Health has highlighted the potential threat that a changing climate poses to the global blood supply. Researchers from the University of the Sunshine Coast and Australian Red Cross Lifeblood have warned that health issues, infectious diseases, and extreme weather events exacerbated by climate change could have a significant impact on the availability of safe blood for medical treatments and emergency situations.
Dr. Elvina Viennet, a researcher at Australian Red Cross Lifeblood and Adjunct Research Fellow at UniSC, emphasized the importance of maintaining a steady supply of blood products for surgeries, trauma care, and chronic disease management. She explained that rising temperatures and natural disasters such as heat waves, floods, and cyclones could disrupt the storage, safety, and transportation of blood, ultimately compromising its availability.
Lead researcher Professor Helen Faddy highlighted the comprehensive nature of the study, which examined the potential risks at each stage of the blood supply chain. The research indicated that climate change could impact infectious diseases transmitted through blood, potentially limiting the pool of eligible donors and increasing the demand for blood transfusions due to various health conditions.
The study also pointed out the need for diversified blood donors to accommodate the increasing migration rates caused by rising sea levels. Dr. Faddy stressed the importance of addressing less obvious health conditions, heat-related illnesses, and psychological distress that could affect donors, staff, and volunteers involved in the blood donation process.
To mitigate the potential risks posed by climate change, the researchers recommended implementing adaptable strategies that can respond quickly to climate-related challenges. These strategies include early warning systems, disease surveillance, flexible donor eligibility criteria, and innovative approaches to blood transport during emergencies.
Recent global innovations such as cell salvage techniques, the use of drones for blood transportation, and walking blood banks were cited as examples of adaptive measures that could enhance the resilience of blood supply chains in the face of climate-related disruptions. The study underscored the importance of reducing reliance on traditional supply chains and embracing innovative solutions to ensure the continuous availability of safe blood products.
