Blood donation is paramount in global healthcare, with over 100 million blood units contributed annually. Blood transfusion is crucial for patients undergoing surgery, coping with trauma, managing chronic illnesses, and battling cancer. This essential procedure serves as a lifeline, providing sustenance and saving lives. Furthermore, donating blood serves as therapeutic phlebotomy for individuals with hereditary hemochromatosis, polycythemia vera, and other rare conditions.[1] This activity provides a brief history of the origin of blood donation and testing and discusses donor eligibility and selection, the adverse effects of donation, pathogen reduction and inactivation methods for donated blood, and the significance of blood donation as a primary medical intervention. In the early 20th century, Karl Landsteiner identified ABO blood groups. During that period, the practice of blood typing for individuals was beginning to be adopted as a universal standard practice.[2] Initially, blood transfusions encountered significant limitations because of the difficulty in clot prevention once the blood was extracted from donors. The transfusion involved directly transferring blood from the donor to the recipient without any intermediate storage or transport. This approach was only effective on a small scale for a limited number of patients, as donors and recipients had to be connected in time and space. Lists of donors comprised individuals locally available for donation at any time. The imperative need for a more flexible donation and storage system arose with the onset of World War I. The concept of "on-demand" blood donation was not viable for such a large-scale effort. Soldiers were succumbing to otherwise non-fatal wounds primarily because timely blood transfusions could not be performed.

Lists of donors comprised individuals locally available for donation at any time. The imperative need for a more flexible donation and storage system arose with the onset of World War I. The concept of "on-demand" blood donation was not viable for such a large-scale effort. Soldiers were succumbing to otherwise non-fatal wounds primarily because timely blood transfusions could not be performed. Concerted efforts to develop a method for storing and transferring blood to meet wartime demands led to several discoveries. Initially, clotting was inhibited by adding citrate to the donated blood.[3] Second, it was observed that adding glucose to the solution enabled red blood cells to maintain viability for several weeks when stored under refrigerated conditions.[4][5] Captain Oswald Hope Robertson of the US Army Medical Corps was the first to "bank" blood in a manner similar to today's practices. In November 1917, before the Battle of Cambrai, Captain Robertson gathered group O blood, combined it with glucose, and stored it. This marked a crucial transition from the earlier method of "direct" to "indirect" blood donation, notably separating donors from their recipients, both geographically and temporally. This advancement significantly enhanced the practicality and utility of blood donation and transfusion.[6]

Certified phlebotomists are mandated to conduct blood donation procedures. These professionals undergo thorough training in screening potential blood donors, using sterile collection methods, and overseeing the blood donation process. Although adverse effects from blood donation are rare, the most frequent complication is the occurrence of a local traumatic hematoma upon needle removal. Applying pressure and using ice or cold compresses in the affected area can aid in preventing the formation or progression of hematomas. While these hematomas are typically small and do not pose significant issues, there is a rare possibility that they may advance to cause damage to neighboring structures and tissues. Therefore, it is crucial to monitor the hematoma closely for the potential development of local damage.[7] The second most common adverse effect of blood donation is syncope, which is often vasovagal or related to hypovolemia. During syncopal episodes associated with blood donation, there is typically a decrease in systolic blood pressure and pulse. The blood donor may experience weakness, sweating, dizziness, or pallor symptoms. The donation is temporarily halted or discontinued, and supportive measures are initiated when syncope occurs. Post-donation syncope may also occur, and the risk can be reduced by having the donor sit in a reclined position for a few minutes. When feasible, donors should gradually transition from a reclined position to an upright one and then move to an area where they can consume food and beverages. Encouraging increased fluid intake and advising against consuming alcoholic or caffeinated beverages over the following few hours can aid in replenishing the lost circulating volume.[7][29][30] One study showed that first-time donor status, young age, and female gender were associated with an increased risk of adverse events. Although transient syncopal events may not be dangerous, injuries sustained from falls due to syncope may result. Thus, it is crucial to mandate rest and sitting during both the blood donation process and the post-donation period to prevent such injuries. Donors who experience injuries during donation may be less inclined to return for subsequent donations.[31][30]

One study showed that first-time donor status, young age, and female gender were associated with an increased risk of adverse events. Although transient syncopal events may not be dangerous, injuries sustained from falls due to syncope may result. Thus, it is crucial to mandate rest and sitting during both the blood donation process and the post-donation period to prevent such injuries. Donors who experience injuries during donation may be less inclined to return for subsequent donations.[31][30] Although nausea and vomiting are reported infrequently with blood donation, if they occur, the donation is temporarily paused, and supportive measures are initiated.[7][32] Other risks include anemia and iron deficiency without anemia. When collecting platelets or plasma via apheresis, red blood cells are not removed, and risks include thrombocytopenia, lymphopenia, and citrate toxicity. Additional risks associated with autologous donation include procedural-induced anemia, loss of donated units due to unforeseen circumstances, and a potential delay in necessary procedures. Ironically, this delay may lead to an increased requirement for allogeneic transfusion in these patients.[9] Despite these considerations, blood donation is generally considered a safe practice, with many individuals perceiving it as an altruistic act. With minimal cost to themselves, donors can significantly contribute to others' healthcare and save lives.

To address the increasing medical demands of our population, we need to boost the blood supply and donor numbers. Hospitals and other establishments continue to create campaigns and motivators to increase the donor pool. These marketing strategies often center around themes of altruism, addressing genuine medical needs, and appealing to a sense of duty and service.[32][36][34] Collaboration among healthcare professionals, hospitals, and blood banks is essential to sustain the required blood donations. Ensuring the protection of blood donors from injury during the donation process is not only inherently important but also crucial for preventing donor dropout and encouraging retention and recruitment.[31][30] The aging population in the United States is steadily growing, and European studies indicate that this trend is diminishing the donor pool.[37] Simultaneously, in-hospital blood needs have significantly increased over the past 3 decades. The collaboration of an interprofessional healthcare team is crucial for educating and initiating blood donation campaigns to expand the pool of donors. Due to the changing demographics, healthcare professionals such as doctors, pharmacists, nurses, phlebotomists, laboratory technicians, and other allied healthcare workers play crucial roles in enhancing blood donations.[37]
