RESUMO

ABSTRACT Introduction: Patient blood management (PBM) programs are associated with better patient outcomes, a reduced number of transfusions and cost-savings The Clinical Decision Support (CDS) systems are valuable tools in this process, but their availability is limited in developing countries This study assesses the feasibility and effectiveness of an adapted CDS system for low-income countries. Methods: This was a prospective study of the PBM program implementation, in a 200-bed tertiary hospital, between February 2019 and May 2020. Outcome measures were red blood cell (RBC), fresh frozen plasma (FFP) and platelet unit transfusions, the transfusion of a single unit of red blood cells and an RBC adequacy index (RAI). Results: Comparing the post-PBM program era with the pre-PBM system era, there was a decrease in red blood cell transfusions (p = 0.05), with an increase in single unit red blood cell transfusions (p = 0.005) and RAI (p < 0.001). Conclusions: The PBM programs, including electronic transfusion guidelines with pre-transfusion medical auditing, was associated with improved transfusion practices and reduced product acquisition-related costs.

RESUMO

Blood transfusions come with risks and high costs, and should be utilized only when clinically indicated. Decisions to transfuse are however not always well informed, and lack of clinician knowledge and education on good clinical transfusion practices contribute to the inappropriate use of blood. Low and middle-income countries in particular take much strain in their efforts to address blood safety challenges, demand-supply imbalances, high blood costs as well as high disease burdens, all of which impact blood usage and blood collections. Patient blood management (PBM), which is a patient-focused approach aimed at improving patient outcomes by preemptively diagnosing and correcting anaemia and limiting blood loss by cell salvage, coagulation optimization and other measures, has become a major approach to addressing many of the challenges mentioned. The associated decrease in the use of blood and blood products may be perceived as being in competition with blood conservation measures, which is the more traditional, but primarily product-focused approach. In this article, we hope to convey the message that PBM and blood conservation should not be seen as competing concepts, but rather complimentary strategies with the common goal of improving patient care. This offers opportunity to improve the culture of transfusion practices with relief to blood establishments and clinical services, not only in South Africa and LMICs, but everywhere. With the COVID-19 pandemic impacting blood supplies worldwide, this is an ideal time to call for educational interventions and awareness as an active strategy to improve transfusion practices, immediately and beyond.

RESUMO

BACKGROUND: Transfusion safety officers (TSO) function as liaisons between the blood bank and clinical staff, utilizing audits, quality improvement, reviews, communication, education, and general vigilance to enhance transfusion safety. While hospitals in Europe and Canada have long employed TSOs, a majority of institutions in the United States (US) have yet to implement this resource, despite the mounting evidence to support their effectiveness. STUDY DESIGN AND METHODS: An anonymous 20-question survey was administered to 104 hospitals with valid email contact information. Survey questions addressed the presence of a TSO, characteristics, backgrounds, and education of TSOs, the reporting and funding structure of the position, and role responsibilities. RESULTS: 53 responses were received, with 52 surveys completed (51 % response rate). The majority of responding institutions have a patient blood management (PBM) program (n = 40, 77 %) and 33 (63 %) have at least 1 TSO. 61 % of TSOs report an educational background in nursing, with 11 additional unique training backgrounds identified. TSO responsibilities are varied and include quality improvement, education, transfusion safety event analysis, and participation in PBM initiatives. Barriers to implementing a TSO position include lack of resources, financial impediments, and a lack of understanding of the position and its value by administrators and clinicians. DISCUSSION: The results of this survey highlight how TSOs contribute to transfusion safety and PBM and may provide guidance to hospitals interested in implementing a TSO position. It also elucidates the range of TSO responsibilities and approaches that institutions utilize to advocate for, and implement, this position in the US.

RESUMO

BACKGROUND: Convalescent plasma (CP) has been used in the past in various pandemics, in particular in H1N1, SARS and MERS infections. In Spring 2020, when ongoing the SARS-CoV-2 pandemics, the Veneto Region (V-R) has proposed setting-up an anti-SARS-CoV-2 CP (CCP) Bank, with the aim of preparing a supply of CCP immediately available in case of subsequest epidemic waves. MATERIALS AND METHODS: Key-points to be developed for a quick set-up of the V-R CCP Bank have been recruitment of donors recovered from COVID-19 infection, laboratory analysis for the biological qualification of the CCP units, including titre of neutralizing antibodies and reduction of pathogens, according to National Blood Centre (CNS) Directives, adaptation of the V-R Information Technology systems and cost analysis. Some activities, including diagnostic and viral inactivation processes, have been centralized in 2 or 3 sites. Laboratory analysis upon preliminary admission of the donor included all tests required by the Italian laws and the CNS directives. RESULTS: From April to August 2020, 3,298 people have contacted the V-R Blood Transfusion Services: of these, 1,632 have been evaluated and examined as first time donors and those found to be suitable have carried out 955 donations, from which 2,626 therapeutic fractions have been obtained, at a cost around 215,00 Euro. Since October 2020, the number of COVID-19 inpatients has had a surge with a heavy hospital overload. Moreover, the high request of CCP therapy by clinicians has been just as unexpected, showing a wide therapeutic use. CONCLUSIONS: The organizational model here presented, which has allowed the rapid collection of a large amount of CCP, could be useful when facing new pandemic outbreaks, especially in low and middle income countries, with generally acceptable costs.

RESUMO

India has almost 3,000 blood centres collecting more than 11 million units annually. Maintaining blood supply during the COVID-19 pandemic is a huge challenge. We conducted a cross-sectional study by an online survey to analyse the variation of practices across blood centers of India during this pandemic. A total of 196 blood centers completely responded to the online survey. Most of the blood centres who responded were part of Government hospitals (60 %), part of an academic institutes (55.6 %) and were directly supporting a COVID hospital (67.5 %). Almost 95.4 % blood centers reported reduction of blood donation mainly due to lockdown (50 %) and inability to conduct camps (17.3 %). Scheduling blood donations was one of the most difficult to implement strategy for maintaining adequate blood donation (40.2 %). Blood center manpower management was also a challenge and upto 48 % blood centers operated in two batches to ensure social distancing in blood banks and reduce the risk of exposure. Hemato-oncology (36.8 %) and obstetrics (33.7 %) were major utilizer of blood during the pandemic. There were marked variations in use of PPE by blood banks staff as well as strategies adopted while conducting immunohematology tests on COVID-19 positive patients samples. This pandemic has highlighted some of the major limitations of the health services but blood services have risen to the challenge and strived to maintain the blood supply chain while ensuring blood donor and staff safety. The wide variations in the practices adopted highlights the need for uniform guidelines for blood services in future pandemics.

RESUMO

Over the past three decades, cord blood transplantation (CBT) has established its role as an alternative allograft stem cell source. But the future of stored CB units should be to extend their use in updated transplant approaches and develop new CB applications. Thus, CBT will require a coordinated, multicentric, review of transplantation methods and an upgrade and realignment of banking resources and operations. Significant improvements have already been proposed to support the clinical perspective including definition of the cellular threshold for engraftment, development of transplantation methods for adult patients, engraftment acceleration with single cell expansion and homing technologies, personalised protocols to improve efficacy, use of adoptive cell therapy to mitigate delayed immune reconstitution, and further enhancement of the graft-versus-leukaemia effect using advanced therapies. The role of CB banks in improving transplantation results are also critical by optimizing the collection, processing, storage and characterization of CB units, and improving reproducibility, efficiency and cost of banking. But future developments beyond transplantation are needed. This implies the extension from transplantation banks to banks that support cell therapy, regenerative medicine and specialized transfusion medicine. This new "CB banking 2.0" concept will require promotion of international scientific and technical collaborations between bank specialists, clinical investigators and transplant physicians.

RESUMO

BACKGROUND: Traditionally, during crises the number of new blood donors increases. However, the current coronavirus disease 2019 (COVID-19) pandemic created additional barriers to donate due to governmental prevention measures and increased personal health risks. In this report, we examined how the pandemic affected new donor registrations in the Netherlands, especially among groups with higher risk profiles for severe COVID-19. Additionally, we explored the role of media for blood donation and new donor registrations. STUDY DESIGN AND METHODS: We analyzed new donor registrations and attention for blood donation in newspapers and on social media from January until May 2020, in comparison to the same period in 2017 to 2019. RESULTS: After the introduction of nationwide prevention measures, several peaks in new donor registrations occurred, which coincided with peaks in media attention. Interestingly, people with a higher risk profile for COVID-19 (e.g., due to age or region of residence) were overrepresented among new registrants. DISCUSSION: In sum, the first peak of the current pandemic has led to increased new blood donor registrations, despite the associated increased health risks. Time and future studies will have to tell whether these new donors are one-off 'pandemic' donors or if they will become regular, loyal donors.

RESUMO

BACKGROUND: Platelets are the most commonly discarded blood product in Canada, with the most common cause of in-date product loss being improper storage. Transport containers to maintain temperature and extend acceptable return time may represent a method to reduce wastage. The objective of this study was to evaluate the impact of a validated Platelet Transport Bag (PTB) on platelet wastage. STUDY DESIGN AND METHODS: Thirty-six hospitals with the highest platelet discards were invited to participate in a before-after observational study. Hospitals were instructed to utilize a validated 4-h PTB for clinical situations where immediate transfusion was not planned. Five hospitals audited in-date platelet discards from July 2018 to November 2019 to characterize wastage causes. In-date platelet discard data 12 months before and after the start date for each site were analyzed to determine changes in wastage. RESULTS: Of 36 hospital sites, 16 agreed to participate. Pre- and postdiscards were 277 and 301, respectively, for all sites combined. There were no significant before-after change in wastage rate (+0.05%, p = .51). Fifty discards were included in the detailed audit; the most common reasons were return to the blood bank after more than 60 min outside a PTB (n = 17, 34%) and return in a red cell cooler (n = 10, 20%). CONCLUSION: Implementation of PTB did not improve wastage. Common causes of in-date discards were return after 1 h outside of a PTB and placement in a red cell cooler in error. Further research is required to investigate potential strategies to mitigate in-date platelet wastage.

RESUMO

BACKGROUND: The COVID-19 pandemic is placing blood and tissue establishments under unprecedented stress, putting its capacity to provide the adequate care needed at risk. Here we reflect on how our integrated organisational model has faced the first impact of the pandemic and describe what challenges, opportunities and lessons have emerged. MATERIALS AND METHODS: The organisational model of the Catalan Blood and Tissue Bank (Banc de Sang i Teixits, BST) is described. The new scenario was managed by following international recommendations and considering the pandemic in a context of volatility, uncertainty, complexity, and ambiguity (VUCA), allowing rapid measures to be taken. These aimed to: ensure donor safety, promote proper responses to patients' needs, ensure the health and well-being of personnel, and prepare for future scenarios. RESULTS: The BST has adapted its activities to the changes in demand. No shortage of any product or service occurred. Donor acceptance, safety and wellbeing were maintained except for tissue donation, which almost completely stopped. To support the health system, several activities have been promoted: large-scale convalescent plasma (CP) production, clinical trials with CP and mesenchymal stromal cells, massive COVID-19 diagnoses, and participation in co-operative research and publications. Haemovigilance is running smoothly and no adverse effects have been detected among donors or patients. DISCUSSION: Several elements have proven to be critical when addressing the pandemic scenario: a) the early creation of a crisis committee in combination with technical recommendations and the recognition of a VUCA scenario; b) identification of the strategies described; c) the integrated donor-to-patient organisational model; d) active Research and Development (R&D); and e) the flexibility of the staff. It is essential to underline the importance of the need for centralised management, effective contingency strategies, and early collaboration with peers.

RESUMO

Unrelated cord blood (CB) units, already manufactured, fully tested and stored, are high-quality products for haematopoietic stem cell transplantation and cell therapies, as well as an optimal starting material for cell expansion, cell engineering or cell re-programming technologies. CB banks have been pioneers in the development and implementation of Current Good Manufacturing Practices for cell-therapy products. Sharing their technological and regulatory experience will help advance all cell therapies, CB-derived or not, particularly as they transition from autologous, individually manufactured products to stored, 'off-the shelf' treatments. Such strategies will allow broader patient access and wide product utilisation.

RESUMO

The now 5-year collaboration between the Indiana Blood Center, now Versiti Blood Center of Indiana, and The Milk Bank has increased the number of human milk donors, improved the collection and processing of donor milk, and improved awareness of this lifesaving resource. The Indiana Blood Center provides greater visibility for The Milk Bank, creating more opportunities to reach potential donors, and can provide the screening blood test for potential donors to become approved human milk donors. The resources of the multiple locations of the Indiana Blood Center permitted the formation of new milk depots in five different cities and quicker transportation of donated milk through their active courier system. This partnership most importantly has improved awareness for both lifesaving missions to the communities they serve.

RESUMO

BACKGROUND: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has spurred a global health crisis. The safety and supply of blood during this pandemic has been a concern of blood banks and transfusion services as it is expected to adversely affect blood system activities. We aim to assess the situation in the Eastern Mediterranean Region (EMR) during the first months of the pandemic. MATERIALS AND METHODS: A survey was designed to address blood supply, transfusion demand, and donor management during the coronavirus disease-19 (COVID-19) pandemic. Medical directors of different blood banks were invited to participate. RESULTS: A total of 16 centers participated with representation from 15/19 countries in the region. In total, 75% were from national blood banks. Most centres had a decrease in the blood supply, ranging from 26-50%. Representatives from 14 countries (93.3%) believed that public fear has contributed to a decrease in donations. Most centres (n=12, 75%) had a reduction in transfusion demand, while those who did not, reported heavy involvement in treating patients with underlying haemoglobinopathies and haematological malignancies. Half of the centres activated their contingency plans. Four centres had to alter the blood donor eligibility criteria to meet demands. All centres implemented donor deferral criteria in relation to SARS-CoV-2, but were variable in measures to mitigate the risk of donor and staff exposure. CONCLUSION: Blood services in the region faced variable degrees of blood shortages. We summarize lessons learnt during this pandemic for the blood banks to consider to plan, assess, and respond proportionately to future similar pandemics.

RESUMO

Umbilical cord blood is an important graft source in the treatment of many genetic, hematologic, and immunologic disorders by hematopoietic stem cell transplantation. Millions of cord blood units have been collected and stored for clinical use since the inception of cord blood banking in 1989. However, the use of cord blood in biomedical research has been limited by access to viable samples. Here, we present a cost-effective, self-sustaining model for the procurement of fresh umbilical cord blood components for research purposes within hospital-affiliated academic institutions.

RESUMO

INTRODUCTION: Numerous concerns regarding maintenance of blood inventory have been raised after SARS-CoV-2 pandemic outbreak. These concerns were based on the experience of blood centres in previous pandemics where shortage of blood components was reported. The present study had tried to understand the impact of SARS-CoV-2 pandemic on blood collection and demand as well as the impact of disaster planning in maintaining an adequate inventory. METHODS: Data related to blood supply and demand were collected retrospectively using blood bank management software for pre-COVID-19 and COVID-19 time period and compared. Strategies adopted and effects of changes in existing disaster plans to maintain an adequate inventory were studied. RESULTS: A drastic fall in the red cell inventory was observed as compared to pre-COVID-19 time period was observed due to disproportionate decrease in blood collection (1/6 to 1/9 of the previous collection) and demand (1/2 of the previous demand). The buffer stock fell gradually over a period of three weeks with cancellation of planned blood donation drives. A buffer stock equivalent to 2-week inventory led to adequate inventory in the initial lockdown periods. Similar fall was observed in the platelet inventory with reduction in the blood collection but almost a proportionate reduction in the platelet demand led to adequate inventory. No increase in wastage was observed for both red cells and platelets during this period. DISCUSSION: A buffer stock of blood and blood components, strict adherence to the transfusion triggers, good coordination with the clinical staff and a prospective review of blood transfusion requests to ensure rational blood transfusion were some of the steps which helped us to successfully maintain transfusion requirements in the initial phases of the COVID-19 pandemic. Use of first-in-first-out policy prevented any wastage due to outdating of blood.

RESUMO

BACKGROUND AND OBJECTIVES: While coronavirus (COVID-19) is not transfusion-transmitted, the impact of the global pandemic on blood services worldwide is complex. Convalescent plasma may offer treatment, but efficacy and safety are not established. Measuring seroprevalence in donors would inform public health policy. Here, we survey blood services around the world to assess the different research programmes related to COVID-19 planned or in progress. MATERIALS AND METHODS: Blood collection services were surveyed in June 2020 to determine whether they were participating in serosurveys or convalescent plasma collection and clinical trials. RESULTS: A total of 48 countries (77% of those contacted) responded. Seroprevalence studies are planned or in progress in 73% of countries surveyed and in all continents, including low- and middle-income countries. Most aimed to inform public health policy. Convalescent plasma programmes have been initiated around the globe (79% of surveyed), about three quarters as clinical trials in high-, middle- and low-income countries. CONCLUSION: Blood services around the world have drawn upon their operational capacity to provide much-needed seroprevalence data to inform public health. They have rapidly implemented preparation of potential treatment when few treatments are available and mostly as clinical trials. At the same time, they must continue to provide blood products for recipients despite challenges of working in a state of emergency. It is important to track and coordinate research efforts across jurisdictions to gain a composite evidence-based view that will influence future practice and preparative strategies.

RESUMO

BACKGROUND: Buffy coat (BC) platelets (PLTs) have been used globally for many years. In 2004 Canadian Blood Services (CBS) made the decision to transition from PLT-rich plasma (PRP) to BC PLTs. We reviewed the benefits and manufacture process of BC and the implementation challenges involved. STUDY DESIGN AND METHODS: A literature review was performed in the following areas: BC efficacy, donor population shifts, production and good stewardship of PLTs, logistic considerations with overnight holds, advantages of the overnight hold, the CBS experience, licensure and standards, and changes needed to produce BC PLTs in the United States. The aim was to analyze current practice and identify possible actions for blood centers and hospitals. RESULTS: Implementation of BC would offer an additional source of PLTs to address the growing elderly population and the declining apheresis donor base. Substantial logistic, operational, and financial benefits were seen when CBS transitioned to BC with overnight hold. CONCLUSIONS: Buffy coat blood products are widely used throughout the world. Recent conversion from PRP to BC by CBS showed that conversion can be accomplished with planning, communication, and partnership from all stakeholders. In conclusion, BC PLTs are worth serious consideration in the United States, but regulatory barriers in the United States will need to be addressed.

RESUMO

The article aims to discuss the consequences of social distancing measures on the availability of blood and organization of blood therapy services at the beginning of the Covid-19 pandemic in Brazil. News published in April 2020 on the websites of the country's state Blood Service Networks were consulted and organized in an Excel spreadsheet, presented in summary charts, and descriptions of results were prepared. A critical situation of blood supply, especially of some blood types, has been observed in many states. This situation is influenced by the circulation of the new coronavirus. The adoption of social distancing measures associated with unchanged transfusion demands for outpatient, urgency and emergency care required the implementation of strategies and actions for the reorganization of the services. Protection measures were incorporated, flows were changed and new routines were established. This study shows the extent to which the epidemiological situation of Covid-19 and the necessary measures for its control influenced the stocks and availability of blood. Changes in the organization of blood therapy services were fundamental in order to ensure protection, mitigate the risks of spreading the virus, and ensure the blood supply to meet the needs of the health system.


O artigo tem por objetivo discutir as consequências das medidas de distanciamento social sobre a disponibilidade de sangue e a organização dos serviços hemoterápicos no início da pandemia de Covid-19 no Brasil. A partir do acesso às notícias publicadas no mês de abril de 2020 nos sites das Hemorredes estaduais do país e organizadas em matriz Excel, foram elaborados quadros-síntese e descrição de resultados. A situação crítica de abastecimento de sangue, em especial para alguns tipos sanguíneos, foi constatada em muitos estados, devido à circulação do novo coronavírus. A adoção de medidas de distanciamento social e a manutenção das demandas por transfusão para tratamentos, urgência e emergência, requereram a implantação e a implementação de estratégias e ações para reorganização dos serviços. Medidas de proteção foram incorporadas, fluxos alterados e rotinas estabelecidas. Este estudo evidencia o quanto a situação epidemiológica da Covid-19 e as medidas necessárias para o seu controle influenciaram sobre a situação dos estoques e disponibilidade de sangue, e, demandaram, mudanças na organização dos serviços hemoterápicos a fim de assegurar a proteção, mitigar os riscos de propagação do vírus e garantir o suprimento de sangue para o atendimento às necessidades do sistema de saúde.
