Transfusion emergency preparedness is increasingly becoming an integrated part of major incident planning. The spectrum of planning extends from the sophisticated healthcare system dealing with multiple casualties, to the isolated healthcare facility resuscitating the critically ill patient with massive haemorrhage. Transfusion preparedness should follow risk assessment and be nested within the wider emergency planning system. The response should be designed to deliver both safety and sufficiency of transfusion support and includes diagnostics, donation and distribution. The biggest transfusion risks in emergency situations are those of red cell ABO incompatibility and delayed provision. Sufficiency and supply may be compromised when communities are isolated and cannot access mutual support. Planning may need to consider local collection and testing of blood as a further resilience measure. Considerations include demand planning; inventory management and transfusion triage; a whole blood preparedness model; resilience and resupply and the human factor. We suggest a whole blood programme can simplify the whole vein‐to‐vein process for production, laboratory and clinical staff and can be integrated into a range of healthcare systems. 相似文献

The activity of Polish Blood Transfusion Service (BTS) is based on the Public Blood Transfusion Service Act voted by the Polish Parliament. There are 21 regional blood transfusion centers, one military blood transfusion center and one blood transfusion center (BTC) of the Ministry of Internal Affairs. The Institute of Haematology and Transfusion Medicine (IHTM) is responsible for issuing guidelines for blood transfusion medicine. All BTCs must have an accreditation from the Ministry of Health. In Poland, there is a national system of haemovigilance. Hospitals are obliged to immediately report all post‐transfusion complications and ‘near‐miss’ events. Immunological, viral, bacterial as well as transfusion‐related acute lung injury reactions are supervised by IHTM. Qualification improvement and training of personnel is one of the priorities of Polish BTS. 相似文献

The ISBT/SITS was founded at the second international congress of blood transfusion in Paris in 1937. The world was influenced heavily by totalitarian ideologies, which a.o. tried to use science to confirm their superiority. The Nazi ideology was built on peculiar speculations on human blood, race and heritage, but although similar ideas were widespread, our society was founded as a purely scientific organization independent of ideological influence. The designation ‘International’ initially signified ‘European’, but after the end of World War 2, our society has become more and more of a global one. 相似文献

In recent years, there has been a concerted effort to improve our understanding of the quality and effectiveness of transfused blood components. The expanding use of large datasets built from electronic health records allows the investigation of potential benefits or adverse outcomes associated with transfusion therapy. Together with information regarding blood donor demographics and component collection and manufacturing, these datasets permit evaluation of associations between donor or component factors and transfusion recipient outcomes. Large linked 'vein‐to‐vein' datasets provide the power to study exposures relevant to transfusion efficacy and safety, many of which would not otherwise be amenable to study for practical or sample size reasons. Analyses of these large donor‐component‐recipient datasets allow for characterization of the populations under study and provide an evidence base for future clinical studies. Knowledge generated from linked analyses has the potential to change the way donors are selected and how components are processed, stored and allocated. However, unrecognized confounding and biased statistical methods continue to be limitations in the study of transfusion exposures and patient outcomes. Given these challenges, results of observational studies of blood donor demographics, storage age and transfusion practice have been conflicting. This review summarizes statistical and methodological challenges in analyses of linked blood donor, component and transfusion recipient outcomes. 相似文献

Automated identification and data capture systems, such as bar code and radio frequency identification (RFID), can be a key enabler for reducing errors and enhancing safety throughout the blood product supply chain. This project was funded by a Small Business Technology Transfer grant from the US National Institutes for Health. It represents the first comprehensive investigation to introduce RFID technology for automatic identification, tracking and monitoring of blood products across the blood banking spectrum. The System covers both blood center and hospital domains. The focus of this paper is to share lessons learned from our pilot, in a hospital domain, as performed at the University of Iowa Hospitals and Clinics (UIHC), in USA. UIHC is a Level I Trauma Center with over 760 beds; it administers more than 34,000 blood products per year. In 2005, UIHC developed a system using bar-code technology named INFORMM Patient Record (IPR) to prevent patient identification errors in blood transfusion. After implementing IPR, UIHC realized substantial improvements in prevention and detection of transfusion errors. The objective of the pilot was to assess RFID technology in transfusion services from four perspectives: safety, operational efficiency, performance reliability, and organizational impact. A significant outcome of this pilot was a comparison between IPR and the RFID System in terms of safety standards and performance. For this purpose, the two systems were run side-by-side using IPR as the benchmark, thus allowing extrapolation of the proven benefits of IPR to the RFID System. The pilot was performed from May 1 until May 28, 2012. The scope was limited to the “Blood and Marrow Transplant Unit” (14-beds) and to a remote storage location in the “Emergency Department”. During the pilot, the RFID and IPR systems collected over 35 samples and processed a total of 144 units. Data was collected from various reports and exception extracts from both systems, and from weekly user survey responses of UIHC personnel involved in the pilot. The RFID System successfully performed all the trace, tracking and safety checks as specified in the processes selected for this pilot. Both the RFID System and the IPR system executed every transaction back-to-back, equally detecting and preventing process errors. Both systems achieved an 83% reduction in process errors by replacing the manual based procedures for tracking and identification purposes. Error reduction also resulted in savings in labor costs. With the RFID System, the visibility and traceability of specimens and products were greatly improved. Our ROI analysis predicts a productivity gain of 10% with a Payback period of 2·5 years and a net present value of benefits equal to $485,000 in a 5 year horizon. The pilot was executed as planned and the assessment of the RFID System was successfully accomplished. Throughout the pilot, the System provided robust functionality equivalent to IPR. The pilot showed that the RFID System can provide high standards of safety for prevention and detection of errors, along with productivity gains. 相似文献

Transfusion medicine is a clinical discipline characterized by one of the most advanced quality management systems, which is structured so as to assure the production of blood components and raw materials, for biopharmaceutical fractionation, that are safe, efficient and effective. During the production, pathogen inactivation and storage processes there is the risk of changes in the integrity of blood components, especially at the protein level. These changes could be the cause of some of the negative effects of transfusion therapy. It is therefore a major challenge to identify significant alterations of these products, and, in this context, proteomics can play a potentially relevant role in transfusion medicine to assess the protein composition of blood-derived therapeutics, particularly for identifying modified proteins. Proteomics can also provide a more detailed understanding of the proteins found in plasma derivatives, with particular regard to peptide and protein changes related to the various procedures used for protein purification and pathogen inactivation during the modern plasma industrial factionation. The latter could cause protein modifications and/or degradation and neoantigen production, with the potential to induce adverse effects in recipients. At present, blood component quality control is mainly focused on standardized quantitative assessment, providing relatively limited information about products. Proteomics allows a comprehensive study of protein modifications, qualitative and quantitative analysis, and high-throughput protein identification. Moreover, being the only tool to evaluate structural changes in proteins (or their degradation products) after their manipulation, and having the capacity to identify many new proteins, proteomics seems to be the most promising tool for global quality assessment and possible improvement of the production process of blood components and plasma derivatives. It can also provide comprehensive information about possible contaminants and neoantigens that may influence the immunogenic capacity of blood-derived therapeutics. 相似文献

A generic definition of quality system describes the organizational structure, responsibilities, processes, procedures and resources required to maintain high quality products and/or services. In blood transfusion chain setting, a quality system provides a framework in a supply chain setting from a donor’s vein to a patient’s vein through the collection, processing, testing, distribution and administration of high quality, safe and effective blood and blood products. 相似文献

In endemic areas, the burden of malaria and anaemia converge together upon children, with severe malarial anaemia (SMA) accounting disproportionately for demands on limited blood supplies. The attributable morbidity and mortality from SMA remain high, and improved outcomes hinge in part on the timeliness, sufficiency and safety of transfusion support. The pathogenesis of SMA is complex, and depreciation kinetics (towards syndrome‐defining haemoglobin levels of <50 g/l) occur acutely or insidiously, and in relation to the parasite burden and host response. Beyond haemolysis of parasitized erythrocytes, mechanisms of bystander loss and reduced erythropoiesis figure prominently, with parallels to hyperhaemolysis syndrome. Involuntarily undertransfused children with SMA in low‐income countries (LIC) differ from those adults in high‐income countries (HIC) who deliberately renounce transfusion. Despite youth‐related advantages in the power to adapt to anaemia, critical reductions in oxygen‐carrying capacity illustrate the hierarchical impacts of organ anoxia, be it in terminal cardiorespiratory events or irreversible neurocognitive impairments in survivors. When resources permit, the dynamics of restored oxygen delivery by transfusion are particularly observable in SMA, as the triggers to transfuse are so much lower (and the odds of corresponding lactic acidosis are so much higher) than in HICs. Questions on the best haemotherapy approaches to SMA remain, be these in dosage, infusion rate, component preparation or matching options; these fundamental concerns now transcend those related to storage duration. As a persisting global scourge, SMA therefore keeps driving and facing the mandate to bank life‐preserving blood for those with the most to gain (and otherwise lose). 相似文献

ObjectivesTo assess the impact of a closed-loop electronic blood transfusion system on transfusion errors and staff time.Materials and methodsBefore and after study in all wards of a children's hospital, involving patients and staff of all the wards. The changes were closed-loop electronic blood transfusion, barcode patient identification, electronic blood transfusion administration records and error pop-up warning. The main outcome measures were percentage of blood transfusion errors, time spent on transfusion tasks.ResultsTransfusion errors were identified in 3.87% of 2556 blood transfusion orders pre-intervention and 0.78% of 2577 orders afterwards (P < 0.01). Phlebotomists, nurses, and physicians may make mistakes, including wrong blood type when apply for blood, wrong patient when blood draw or transfusion, wrong dose when apply for blood and the wrong tube label when blood draw or cross-matching, which are significantly reduced after change (1.09% vs 0.31%, 1.13% vs 0%, 0.31% vs 0%, 1.33% vs.0.78%, P < 0.01). Time spent on blood apply was 5.3 ± 1.2 min, hand over blood bag at the transfusion department was 14.9 ± 1.4 min and blood transfusion was 15.8 ± 2.4 min. Time per transfusion round decreased to 2.6 ± 1.0 min, 6.3 ± 1.6 min and 9.3 ± 2.2 min respectively (P < 0.01).ConclusionsA closed-loop electronic blood transfusion, barcode patient identification and error pop-up warning reduced transfusion errors, and increased confirmation of patient and blood types identity before transfusion. Time spent on blood transfusion tasks reduced. 相似文献

The history of the ISBT since its foundation in 1937 may be divided into four phases: (i) Formation and development (1935–1985), (ii) Years of crisis (1985–2000), (iii) Reformation (2000–2010), (iv) A professional organization (2010–present). While the ISBT was initially founded to organize congresses, today it stands forth as a global, diversified and respected scientific organization in the field of transfusion, also having an educational branch and governing international reference functions. During the last 25 years, women have taken a more prominent role in the organization. The challenge for the future is for ISBT to be the Society of first choice for professionals in the field of transfusion medicine and cellular therapies. 相似文献

As a consequence of the September 2001 terrorist events, programs to protect against further such acts including potentially the use of biological warfare agents have been launched in the USA and elsewhere. As part of these initiatives, Vaccinia virus was procured for the pre-emptive vaccination of key personnel against smallpox as well as population-wide protection after an eventual exposure. The introduction of this live virus into a population at a relatively large scale represents a theoretical challenge for the safety of the blood supply, and potentially for plasma for fractionation. To strengthen further the demonstration of safety margins for plasma derived products against Vaccinia virus, the capacity of sterile filtration procedures to remove the virus was investigated. An infectivity assay for the Vaccinia virus strain which represents the majority of smallpox vaccine stocks available currently was used to investigate the potential removal of this virus by sterile filtration processes during the manufacture of plasma derivatives. Vaccinia virus behaves as predicted based on its size, i.e., an artificially added virus load is removed about 10,000-fold by the sterile filtration procedures tested. As the current investigation covered a range of different protein concentrations, filter materials and filters from different manufacturers, the results obtained are considered to be widely applicable. The current investigation supports further the high safety margins of plasma derivatives against any potential Vaccinia virus content of plasma for fractionation. As the large size is a general feature of Orthopox viruses, the results would also provide assurance against poxviruses identified more recently, for example, Monkeypox virus. 相似文献
