Currently blood is a volatile issue. The safety of blood and the quantification of transfusion risks have been dominant themes that have stimulated the development of alternative approaches in this rapidly developing area. In clinical medicine conventional blood and its components are used in supportive therapies dependent on the choice of apparent uncritical trigger factors. A compounding factor is depth of prospective clinical trials for evidence. Such trials in critical care areas would be of enormous value, not only in recording adverse effects and under-transfusion, but also indicating the value of decision analysis and cost-effectiveness in transfusion practice. Alternative approaches include the use of cytokines, growth factors, humanised monoclonal antibodies, recombinant plasma factors, and buffy coat derived natural human interferons. These are being increasingly implemented in the clinic. Solutions for oxygen transport are being developed and fibrinogen coated microcapsules are being investigated for thrombocytopenia. In surgical patients, various crystalloid and colloid combinations are explored as volume replacements. To avoid allogeneic transfusions, beneficial blood saving methods include various strategies, such as autologous deposits, normovolemic haemodilution and various agents including aprotinin, tranecamic acid, desmopressin and erythropoietin, but their use in hospital shows considerable variations. That umbilical cord blood could be a significant source of allogeneic stem cells in related and unrelated transplantation is illustrated by the increasing number of cord blood banks in Europe and elsewhere. Future blood resources are likely to face several challenges: immediate challenges relate to increased regulatory and political oversights; intermediate solutions would offer some improvements in public health and alleviate public fear but probably not address the economic challenges thrust upon the medical care system. As we approach the year 2000, the major concerns about transfusion medicine remain its logistics, safety and effectiveness. This theme is presented in the proceedings of the 22nd International Symposium on Blood Transfusion, developed in 21 up-to-date topics, collected and discussed in four sections. This book will be of timely value to students, professionals and all others interested or involved in the field of transfusion medicine, whether clinical or related.

The international symposia on blood transfusion in Groningen have taken place without interruption since 1976. Each year Dr. Smit-Sibinga and his team have not only organized a meeting on timely topics in blood transfusion, but also succeeded in attracting prominent chairmen and speakers. The subject of the 24th Symposium was Molecular Biology in Blood Transfusion and it was chaired by Dr. Harvey G. Klein, National Institutes of Health, USA. In this book of proceedings an extraordinary range of subjects is covered, including diagnostic aspects, virology, quality control, cell and protein processing as well as a section on new horizons in clinical medicine.

Healthcare decision makers in search of reliable information that compares health interventions increasingly turn to systematic reviews for the best summary of the evidence. Systematic reviews identify, select, assess, and synthesize the findings of similar but separate studies, and can help clarify what is known and not known about the potential benefits and harms of drugs, devices, and other healthcare services. Systematic reviews can be helpful for clinicians who want to integrate research findings into their daily practices, for patients to make well-informed choices about their own care, for professional medical societies and other organizations that develop clinical practice guidelines. Too often systematic reviews are of uncertain or poor quality. There are no universally accepted standards for developing systematic reviews leading to variability in how conflicts of interest and biases are handled, how evidence is appraised, and the overall scientific rigor of the process. In Finding What Works in Health Care the Institute of Medicine (IOM) recommends 21 standards for developing high-quality systematic reviews of comparative effectiveness research. The standards address the entire systematic review process from the initial steps of formulating the topic and building the review team to producing a detailed final report that synthesizes what the evidence shows and where knowledge gaps remain. Finding What Works in Health Care also proposes a framework for improving the quality of the science underpinning systematic reviews. This book will serve as a vital resource for both sponsors and producers of systematic reviews of comparative effectiveness research.

Clinical Ethics introduces the four-topics method of approaching ethical problems (i.e., medical indications, patient preferences, quality of life, and contextual features). Each of the four chapters represents one of the topics. In each chapter, the authors discuss cases and provide comments and recommendations. The four-topics method is an organizational process by which clinicians can begin to understand the complexities involved in ethical cases and can proceed to find a solution for each case.

th It is a great pleasure for me to open the jubilee 25 International Symposium on Blood Transfusion here in Groningen. This symposium is co-sponsored by the World Health Organization and is being held under the auspices of the ISBT and the Secretary General of the Council of Europe, Mr Walter Schwimmer. The patronage was granted with great pleasure for several reasons. First of all, Dutch experts are very active in our Committees and have largely contributed in developing the Council of Europe principles in the blood area. Secondly, the Council of Europe is active today in the area of blood transfusion due to a tragic event, which occurred in 1953 in the Netherlands; following a flooding many of the blood products given for assistance' could not be used due to incompatibilities and differences in labelling. Some words to present the Council of Europe since the organisation is sometimes confused with institutions ofthe European Union: The organisation has been founded in 1949 to establish the principles of democracy and rule of law all over Europe. Since 1989, the year of the fall of the Berlin wall and the opening up of the iron curtain, these principles could be extended to the countries of Central and Eastern Europe. Today this makes the Council of Europe the only pan-European organisation with 41 Member States thus representing more than 750 million people.

Patient Blood Management (PBM) is an innovative clinical concept that aims to reduce the need for allogenic blood transfusions, cut health-care costs, and avert or correct the risk factors related to blood transfusion, thus minimizing the rate of side effects and complications. This comprehensive hands-on volume offers a three-point approach for the implementation of PBM to improve patient outcome, focusing on how to prevent or treat anemia, reduce blood loss, and increase anemia tolerance. The book also goes beyond preoperative PBM, with detailed accounts of coagulation disorder management and the administration of coagulation products and platelet concentrates. Special Features: Presents a clear three-pillar strategy for the application of PBM: diagnosis and treatment of anemia, reduction of peri-interventional blood loss, and optimization of the tolerance to anemia in the everyday clinical setting Covers issues such as PBM during surgery, requirements for modern transfusion medicine, ordering blood products, the role of pre-anesthesia clinics, benchmarking processes, and potential implications of PBM in the public health sector Overview of research in PBM including landmark studies and current clinical trials Boxes in each chapter highlighting key information, core statements, and summaries A multidisciplinary and international team of contributors experienced in PBM Patient Blood Management is a guide for clinicians and residents whose patients are at risk for anemia, coagulation disorders, or severe blood loss. Anesthesiologists, surgeons, and specialists involved in the use of blood and blood products can use the book for quick reference or to learn more about a leading-edge concept for optimizing patient safety and improving outcome.
