Blood product safety has been an improving area of focus for many countries over recent decades (see Figure. Blood Product Safety). The World Health Organization promotes efforts to improve access to safe transfusion and blood products worldwide. Safety of blood products begins with blood donor recruitment and includes: Emphasis on pre-donation information Blood component collection, preparation, and testing Post-donation information collection Labeling of the blood products for distribution Handling of blood products in the hospital inventory Blood transfusion into the patient by hospital staff Culminating with hemovigilance and clinical quality improvement to ensure patient safety and to reduce the morbidity and mortality associated with blood transfusion [1] Several methods have been employed to reduce the risk of blood transfusions and improve blood product safety. There have been interventions in every step of the process, from before blood donation collection through post-procedure follow-up of blood product recipients. There have been improvements made in the collection, storage, management, distribution, utilization, and monitoring of transfusions.

Several methods have been employed to reduce the risk of blood transfusions and improve blood product safety. There have been interventions in every step of the process, from before blood donation collection through post-procedure follow-up of blood product recipients. There have been improvements made in the collection, storage, management, distribution, utilization, and monitoring of transfusions. The measures for improved safety begin even before blood collection. It is essential to have the commitment of both the government and professional organizations to improving the safety of blood products. Other important aspects of improving safety include proper training of staff, along with a dedicated and diligent blood transfusion organization overseeing donation, testing, and eventual transfusion. Blood donor recruitment is a crucial next step in ensuring the safety of blood products. Voluntary, unpaid donors have the lowest rates of transfusion-associated infections and are the ideal population from which to recruit donors for transfusion purposes. 'Replacement' and 'family' donors are falling out of favor. Donor screening questions add a layer of defense to improve blood product safety. These screening questions are responsible for the single most significant reduction in transfusion-transmitted infections. Donors are deferred based on criteria developed to ensure the safety of both the donor and the potential recipient. Donors can be deferred for a period (as in the case of anemia) or indefinitely (as in the case of a donor who has tested positive for HIV and confirmed to have HIV). Laboratory testing of blood donations also provides an additional layer of protection against transfusion-associated adverse events. Blood group compatibility testing, along with additional antibody testing and molecular testing for known transfusion-transmitted infections, occurs. Guidelines to ensure the diligent and appropriate use of blood transfusions improve safety and reduce adverse outcomes for patients receiving a transfusion. Close clinical correlation and monitoring of symptomatic response also improve patient outcomes. Monitoring of transfusion has improved over time, with a greater emphasis placed on the accurate detection and evaluation of transfusion reactions. Transfusion alternatives and extended shelf life options have expanded the scope of transfusion and have the potential to improve the blood supply. A summary of the strategies for reducing the risks associated with blood and blood products is shown in Figure 1.

According to the World Health Organization Guidelines on Drawing Blood: Best Practices in Phlebotomy, complications of blood donation include (from most likely to least likely) a hematoma, vasovagal reaction or syncope, delayed syncope, arterial puncture, and nerve damage. Complications of blood transfusion include transfusion reactions and transfusion-transmitted infections.[23] The risk of transfusion-transmitted infection has fallen very low in high-income countries, with a risk of less than 1 in 1 million for most of the concerning pathogens, such as HIV, HCV, and HBV.[17] Donor screening techniques that select blood from only low-risk donors have had the most significant impact on reducing pathogens transmitted through transfusion. Exclusion criteria include medical history, high-risk behaviors, physical examination findings, geographic, and travel exclusions. There are also serologic and nucleic acid tests that have reduced the risk of transmission by infectious agents. It is worth noting that laboratory testing may not detect all pathogens due to a small number of false-negative tests. Therefore, screening questionnaires remain vital to eliminate high-risk donors. Donating blood should never be seen as an easy way to find out about the infectious disease status of at-risk persons. Although the risk of transfusion-transmitted infection has decreased substantially, bacterial contamination in platelets stored at room temperature is still a concern for potential septic transfusion reactions. Bacterial contamination is typically caused by commensal bacteria normally found on the skin of donors or by transient bacteremia in donors. Another growing concern is the transmission of emerging pathogens through transfusion, such as the Zika virus and babesiosis. As the risk of infectious complications has decreased, noninfectious transfusion complications have become the primary area of concern and focus for improvement. The efforts focused on detecting, recognizing, and reporting transfusion-related adverse events have improved the safety of blood and blood component transfusions. Transfusion reactions that can occur with blood transfusion range from life-threatening to circumstances in which transfusion can continue once the cause of the reaction is determined (eg, simple allergic reaction). The most common reactions include the following:

The most common reactions include the following: Transfusion-associated circulatory overload Transfusion-related acute lung injury (TRALI) Transfusion-associated dyspnea Simple allergic reaction Anaphylactic reaction Hypotensive transfusion reaction Febrile non-hemolytic transfusion reaction Acute hemolytic transfusion reaction Delayed hemolytic transfusion reaction Delayed serologic transfusion reaction Transfusion-associated graft vs. host disease Post-transfusion purpura Transfusion-transmitted infection [23] With efforts to reduce TRALI, transfusion-associated circulatory overload has been an emerging concern for morbidity and mortality in patients receiving blood transfusions.[24] Improved awareness around transfusion reactions and their etiology has improved blood product safety.[25][26][27][28] Estimated incidence rates for several of the complications of transfusion and specific transfusion-related adverse events are shown in Figure 3.[29][30][31][32]

Nurses, trained technical staff, and phlebotomists are involved in collecting, screening, modifying blood, and monitoring blood donors throughout the donation process in a safe and standardized manner. Laboratory personnel play a crucial role in ensuring the safe testing and handling of blood products. Nurses and laboratory technologists play a pivotal role in verifying patient information and ensuring that the correct blood product gets to the right patient at the right time. Nurses who monitor and document patient vital signs and symptoms during blood transfusions play a crucial role in ensuring patient safety and in identifying possible transfusion reactions. Pharmacists and clinicians assist patients with known allergic reactions or febrile non-hemolytic transfusion reactions during blood transfusions. In the case of mild allergic transfusion reactions, medication is provided to help alleviate the reaction, allowing the transfusion to resume. Physicians work closely with the blood bank at their institution to coordinate care and provide blood in a timely and sensitive manner. Communication on multiple levels of an interprofessional team caring for patients is critical for this life-saving procedure to be effective and safe for patients. Transfusion safety officers and related professionals play a crucial role in monitoring blood transfusion criteria and physician ordering of blood products, thereby contributing to transfusion mindfulness and hemovigilance efforts.[44][45]
