Serologic screening for viral infections among blood donors: a study in a blood bank in southern Brazil.

BACKGROUND: Routine screening for viral infections at blood donation is important to avoid transfusion-transmitted infections. It also offers an opportunity to detect an asymptomatic infection. OBJECTIVE: To study changes in serology positivity for viral infections (B and C hepatitis, HTLV-1/2, and HIV) at blood donation in a blood bank from Southern Brazil, comparing two periods of 5 years: the period from 2013 to 2017 with the period from 2018 to 2022. In addition, data on the donor fidelity rate during the studied period were sought. METHODS: Retrospective study using data from 2013 to 2022 from a single blood center electronic database from Curitiba, Southern Brazil. RESULTS: A significant drop in positive serology for all studied viruses was observed: highest in HIV (OR=0.39; 95% CI=0.27-0.57) and lowest in total anti HBc (0.56; 95 CI=0.50-0.63). Anti HBc serology became more commonly seen in women in the period of 2018-2022 when compared to men. No changes in the distribution of positive serology according to donors' ages were observed. Loyalty rates had a median of 70%, with the lowest being 60% in 2013, while the highest was 73% in 2018 and 2022. CONCLUSION: A significant reduction in discarded blood bags due to viral serology was observed when the period of 2013-2017 was compared to 2018-2022 on this blood bank; the highest reduction was observed in HIV serology and the lowest in HBc serology, which became more common in women in the second period. High rates of donor fidelity were observed during the period studied.

Prevalence and Factors Associated with transfusion-transmissible infections among blood donors in Arua regional blood bank, Uganda.

BACKGROUND: Blood transfusion services play a very key role in modern health care service delivery. About 118.5 million blood donations were collected globally in 2022. However, about 1.6 million units of blood are destroyed annually due to transfusion-transmissible infections (TTIs). There is a very high risk of TTIs through donated blood to recipients if safe transfusion practices are not observed. This study determined the prevalence and factors associated with TTIs among blood donors in Arua regional blood bank, Uganda. METHODS: This study was a retrospective cross-sectional design that involved a review of a random sample of 1370 blood donors registered between January 1st, 2018 and December 31st, 2019 at Arua regional blood bank, Uganda. Descriptive statistics were used to describe the characteristics of the blood donors. The binary logistic regression was used to determine the factors associated with TTIs. RESULTS: The majority of the blood donors were male (80.1%), and the median donor age was 23 years (IQR = 8 years). The overall prevalence of TTIs was found to be 13.8% (95%CI: 12.0-15.6%), with specific prevalences of 1.9% for HIV, 4.1% for HBV, 6.6% for HCV and 2.8% for treponema pallidum. Male sex (AOR = 2.10, 95%CI: 1.32-3.36, p-value = 0.002) and lapsed donor type compared to new donor type (AOR = 0.34, 95%CI: 0.13-0.87, p-value = 0.025) were found to be associated with TTIs. CONCLUSION: The prevalence of TTIs among blood donors of West Nile region, Uganda was found to be significantly high, which implies a high burden of TTIs in the general population. Hence, there is need to implement a more stringent donor screening process to ensure selection of risk-free donors, with extra emphasis on male and new blood donors. Additionally, sensitization of blood donors on risky behaviors and self-deferral will reduce the risk of donating infected blood to the recipients.

Analysing lapsing rates among first-time blood donors at a blood centre in Zimbabwe using survival analysis.

Introduction: blood centres are often faced with the problem of donor lapsing resulting in loss of donors from the already strained donor pool. In Zimbabwe, 70% of the donated blood comes from younger donors aged 40 years and below, who at the same time, have high attrition rates. This study seeks to apply the concept of survival analysis in analysing blood donor lapsing rates. Methods: in analysing the donor lapsing and retention rates, data on 450 first-time blood donors at the National Blood Service Zimbabwe, in Harare´s blood bank for the period 2014 to 2017 was extracted from the donors´ database. The Cox proportional hazards (Cox PH) and Kaplan-Meier methods were applied in the analysis. Donor demographic characteristics suspected of having effect on donor lapsing and retention were identified and analysed. Results: the study findings show that 56.9% of the donors had lapsed by the end of the four-year study period. Results from the multiple Cox PH model indicate that donor age had a significant effect on blood donor retention time (p = 0.000918 < 0.05). The hazard ratio (HR) = 0.615 with 95% CI: (0.461; 0.820) shows that the relatively older donors had a lower hazard (38.5% lower) of lapsing compared to the hazard for younger donors. The effect of gender, blood donor group and donation time interval on donor retention and attrition were not statistically significant. Male donors had HR = 1.03; 95% CI (0.537; 1.99) with (p = 0.922 > 0.05) and donors with a 4-month interval between donations had HR = 1.31; 95% CI (0.667; 2.59) with (p = 0.430 > 0.05). Conclusion: the study confirmed the problem of donor attrition faced by blood centres. The age of the donor had a significant effect on the retention time of blood donors before lapsing. The older the blood donor, the lower the risk of lapsing. The Zimbabwe National Blood Service (NBSZ) Blood Centre authorities should have a critical mass of individuals above 40 years as potential blood donors because of their reliability in blood donation according to the study findings.

[Prediction of the clinical supply of blood components in Xi'an City from 2023 to 2025].

Objective: To construct a prediction model for the clinical supply of blood components in Xi'an City from 2023 to 2025. Methods: Based on the blood supply data of the Blood Management Information System of Shaanxi Provincial Blood Center from January 2013 to December 2022, a gray prediction model and an exponential curve fitting model were used to construct the prediction model, and the optimal prediction model was determined according to the error parameters of the relevant indicators of the model. The supply of blood components in Xi'an from 2023 to 2025 was predicted. Results: The fitting equations of the exponential curve fitting model to predict the supply of suspended red blood cells, platelets and cryoprecipitate in Xi'an were, x（1）（t+1）=1.16e0.04t，x（1）（t+1）=1.04e0.12t and x（1）（t+1）=1.01e1.10t, respectively. The mean absolute errors (mean relative errors) of the exponential curve fitting model in predicting the supply of suspended red blood cells, platelets and cryoprecipitate in Xi'an were 10 488.7 (0.05%), 2 114.9 (0.08%) and 3 089.6 (0.07%), respectively, which were lower than those of the gray prediction model, about 10 488.7 (3.44%), 2 152.78 (8.20%) and 3 441.35 (7.92%), respectively. The exponential curve fitting model predicted that the clinical supply of blood components in Xi'an would increase year by year from 2023 to 2025, and the clinical supply of suspended red blood cells, platelets, and cryoprecipitate in Xi'an would increase to 409 467 U, 69 818 therapeutic volume and 94 724 U, respectively by 2025. Conclusion: The exponential curve fitting model can make a good prediction of the clinical supply of blood components in Xi'an City.

Mitigation of supply chain challenges in cell therapy manufacturing: perspectives from the cord blood alliance.

Cellular therapies rely on highly specialized supply chains that often depend on single source providers. Public cord blood banks (CBB) manufacturing the first cell therapy to be highly regulated by the FDA and related international agencies are a prime example of being subject to this phenomenon. In addition to banking unrelated donor cord blood units for transplantation, CBBs also source and characterize starting materials for supply to allogeneic cell therapy developers that often employ customized technologies offered by just a small number of manufacturers. As such, these supply chains are especially sensitive to even minor changes which often result in potential major impacts. Regulations can shape supply chain efficiencies, both directly via the definition of restricted technology and process requirements and indirectly by steering strategic business decisions of critical supply or service providers. We present 3 current supply chain issues with different root causes that are swaying efficiencies in cord blood banking and beyond. Specifically, the shortage of Hespan, a common supplement used in cord blood processing, the decision by the provider to stop supporting medical device marking of the Sepax system broadly used in cord blood banking, and a new European ruling on phasing out plasticizers that are critical for providing flexibility to cord blood collection bags, are all threatening downstream supply chain issues for the biologics field. We discuss overcoming these hurdles through the prism of unified mitigation strategies, defined, and implemented by multi-factorial teams and stakeholders, to negotiate resolutions with providers and regulators alike.

Transfusion transmitted infections among blood donors of Kamenge Teaching Hospital blood bank in Burundi.

Background: The current risk of contracting a transfusion transmitted infections (TTIs) is unknown in Burundi. Objectives: The aim of this study was to assess sociodemographic profiles of blood bank donors at Kamenge Teaching Hospital, the prevalence and associated risk factors of HIV, syphilis, HBV and HCV from 2015 to 2020. Methods: We conducted a cross-sectional study including all blood donors of Kamenge Teaching Hospital blood bank. During this study, 1370 blood samples were screened for HIV, Syphilis, HBV and HCV. We calculated prevalence of TTIs and performed logistic regression to know associated risk factors. Results: Blood donors were males at 77% and 23% females. They were mostly students (54.2%). On screening, 83 blood samples (6.06%) were seropositive for at least one TTI. The overall prevalence rate of HIV, Syphilis, HBV and HCV among blood donors was 1.3%, 0.2% ,1.6%, 2.9% respectively. There was difference in distribution of the four TTIs among blood donors which is statistically significant (x2=33.997, ϱ-value<0.001). Private donors were associated with a high risk of syphilis and being a first-time donor was associated with a high HBV risk factor. Conclusion: The prevalence of TTIs found still to be high; mandatory and continuous screening is necessary.

The thin red line: Blood planning factors and the enduring need for a robust military blood system to support combat operations.

ABSTRACT: Battlefield lessons learned are forgotten; the current name for this is the Walker Dip. Blood transfusion and the need for a Department of Defense Blood Program are lessons that have cycled through being learned during wartime, forgotten, and then relearned during the next war. The military will always need a blood program to support combat and contingency operations. Also, blood supply to the battlefield has planning factors that have been consistent over a century. In 2024, it is imperative that we codify these lessons learned. The linchpins of modern combat casualty care are optimal prehospital care, early whole blood transfusion, and forward surgical care. This current opinion comprised of authors from all three military Services, the Joint Trauma System, the Armed Services Blood Program, blood SMEs and the CCC Research Program discuss two vital necessities for a successful military trauma system: (1) the need for an Armed Services Blood Program and (2) Planning factors for current and future deployed military ere is no effective care for wounded soldiers, and by extension there is no effective military medicine.

Long-term prediction of Iranian blood product supply using LSTM: a 5-year forecast.

BACKGROUND: This study aims to predict the trend of procurement and storage of various blood products, as well as planning and monitoring the consumption of blood products in different centers across Iran based on artificial intelligence until the year 2027. METHODS: This research constitutes a time-series investigation within the realm of longitudinal studies. In this study, information on the number of packed red blood cells (RBC), leukoreduced red blood cells (LR-RBC), and platelets (PLT), PLT-Apheresis, and fresh frozen plasma (FFP) was requested from all blood transfusion centers in the country and extracted using a unified protocol. After the initial examination of the information and addressing data issues and inconsistencies, the corrected data were analyzed. Both conventional and artificial intelligence approaches were used to predict each product in this study. The best model was selected based on goodness-of-fit indicators RMSE and MAPE. RESULTS: Based on the obtained results, the FFP product will follow a relatively consistent process similar to previous years in the next five years. The PLT product is predicted to have a growing trend over the next 5 years, which applies to both the demand and supply of the product. The PLT-Apheresis product also shows a similar upward trend, albeit with a lower growth rate. The RBC product will have a constant trend over a 5-year period (long-term) according to both models, taking into account short-term changes. Similarly, there is a similar trend in LR-RBC, with the expectation that short-term pattern repetition will continue over a 5-year period (long-term). Comparing the goodness-of-fit results, the LSTM model proved to be better for predicting the dominant blood products. CONCLUSIONS: The growth of the elderly population and diseases related to old age, and on the other hand, the trend of increasing the consumption of the product with a short lifespan (PLT) requires the activation of the management of the patient's blood, especially in relation to this product in medical centers. The trend for other products in the next five years is similar to previous years, and no growth in demand is observed. The LSTM method, considering periodic and cyclical events, has performed the prediction.

Irregular red blood cell antibodies, abnormal hemoglobin and dangerous universal blood donor insights from a public blood center in a Brazilian metropolitan area.

BACKGROUND: Immunohematology tests are crucial in transfusion safety. This study aimed to assess irregular red blood cell (RBC) antibodies, abnormal hemoglobin and dangerous universal blood donors at a public blood center in a Brazilian metropolitan area. METHODS: A cross-sectional study included all consecutive blood donors from January 2018 to December 2021 at the Brasília Blood Center Foundation, Federal District (FD), Brazil. RESULTS: Among 205,965 blood donations, irregular RBC antibodies were found in 743 (0.4 %). Abnormal hemoglobin was observed in 5396 (2.6 %): 3959 (1.9 %) with Hb AS, 1344 (0.7 %) with Hb AC, and 93 (< 0,1 %) with other hemoglobin variants. Of O group donors, 12.5 % (9646) had hemolysins: 12.5 % (2410) both anti-A and anti-B, 8.7 % (9646) only anti-A, and 1.6 % (1763) only anti-B hemolysins. Female sex (p < 0.001) and increasing age (p < 0.001) were associated with irregular RBC antibodies. O and/or Rh(D)-positive blood groups had a lower prevalence of irregular RBC antibodies compared to other ABO and/or Rh(D)-negative groups. Age (p < 0.001) and female sex (p < 0.001) were associated with anti-A/anti-B hemolysins, while FD residency was associated with reduced incidence (p < 0.001). CONCLUSION: Anti-A/anti-B hemolysins in O group donors, abnormal hemoglobin and irregular RBC antibodies pose risks to transfusion practice and should not be overlooked. Advancing age, female sex, ABO blood group other than O, or Rh(D)- negative are independently associated with the presence of irregular RBC antibodies. Dangerous universal blood donors were associated with advanced age, female gender, Rh(D)-positive blood type, and individuals residing in a Brazilian state other than where the blood center was located.

How do I implement pathogen reduced Cryoprecipitated fibrinogen complex in a tertiary Hospital's blood Bank.

BACKGROUND: Kaiser-Permanente Los Angeles Medical Center (LAMC) is a 560 licensed bed facility that provides regional cardiovascular services, including 1200 open heart surgeries annually. In 2021, LAMC explored alternative therapies to offset the impact of pandemic-driven cryo AHF shortages, and implemented Pathogen Reduced Cryoprecipitated Fibrinogen Complex (also known as INTERCEPT Fibrinogen Complex or IFC). IFC is approved to treat and control bleeding associated with fibrinogen deficiency. Unlike cryo AHF, IFC has 5-day post-thaw shelf life with potential operational and clinical benefits. The implementation steps and the operational advantages to the LAMC Blood Bank are described. STUDY DESIGN AND METHODS: Eighteen months post-implementation, the institution reviewed their product implementation experience and compared IFC with cryo AHF with a retrospective review of transfusion service and cardiac post-op data. RESULTS: IFC significantly decreased product wastage rates and order-to-issue time. It did not significantly impact post-op product utilization or hospital length of stay (LOS) in cardiac surgery patients when compared with cryo AHF. DISCUSSION: Implementation of IFC provides improved product supply stability, shorter turnaround times, and reduced wastage.

Criteria for storage of cord blood units at Japan's largest cord blood bank.

BACKGROUND AND OBJECTIVES: In Japan, cord blood transplantations exceed those done with adult-sourced unrelated stem cells. This study analyses cord blood (CB) storage criteria to maintain high-quality CB units. MATERIALS AND METHODS: The Kanto-Koshinetsu Cord Blood Bank received 29,795 units from 2014 to 2021, mostly >60 mL, and 5486 (18.4%) were stored as transplantable units. We investigated the mother's gestational period, CB volume, total nucleated cells (TNCs), CD34+ cells, total colony-forming units (CFUs), time from collection to reception and cryopreservation, cell viability, and the reasons for not storing a unit. RESULTS: The average time from collection to reception of 29,795 units was 18.0 h. The most common reason for not storing a CB unit was low cell numbers (pre-processing TNC count <1.2 billion), accounting for 67.9% of the units received. There was no correlation between the CB volume and the CD34+ cell count. The shorter the gestational period, the lower the TNC count, but the higher the CD34+ cell count. There was no correlation between the time from collection to cryopreservation, within a 36-h time limit, and the CD34+ cell recovery rate. CONCLUSION: We could accept units with a TNC count <1.2 billion and a CB volume <60 mL from a gestational period of 38 weeks or less if we did a pre-processing CD34+ cell count. This would secure more units rich in CD34+ cells.

A generic blood banking and transfusion process-oriented architecture for virtual organizations.

BACKGROUND: Blood banks are an important part of healthcare systems. They embrace critical processes that start with donor recruitment and blood collection, followed by blood processing to produce different types of blood components used in transfusions, blood storage, blood distribution, and transfusion. Blood components must be generated at high quality, preserved safely, and transfused in a timely manner. This can be achieved by operating interrelated processes within a complex network. There is no comprehensive blueprint of Blood Banking and Transfusion (BB&T) processes and their relationships; therefore, this study aims to develop and evaluate a BB&T process architecture using the Riva method. RESEARCH DESIGN: This research adopts a design science research methodology process (DSRM) that aims to create artifacts for the purpose of serving humanity through six phases: identifying problems, identifying solutions and objectives, designing and developing artifacts, demonstrating and evaluating the artifacts, and communicating the work. The adapted DSRM process is used to build a process architecture in the BB&T unit to improve the quality and strategic planning of BB&T processes. Applying the adapted DSRM process generated four increments before the outcomes were communicated as a highly comprehensive BB&T process architecture (BB&TPA) blueprint for virtual organizations. Finally, the generated BB&TPA is tested and validated at a reference hospital. RESULTS: A Riva-based process architecture diagram was successfully developed, acting as a reference model for virtual BB&T organizations. It is a novel output in the domain of BB&T and can also be considered as a reference model to evaluate the existing processes in BB&T real-world units. This assists domain experts in performing gap analysis in their BB&T units and paths for developing BB&T management information systems and can be incorporated in the inspection workflow of accreditation organizations.

Evaluation of the quality of platelet concentrates obtained in a Peruvian hospital.

Introduction: Platelet concentrates are blood products obtained from donor's blood, and their conservation must be subject to a strict quality control process to guarantee a safe and high-performance product in treating diseases that require their use. Methods: We designed a cross-sectional study to determine the total compliance rate in platelet concentrates obtained in the blood bank of the Cayetano Heredia Hospital in Lima during November and December of 2019. The Buffy method Coat obtained the platelet concentrates, and parameters such as platelet count and residual leukocytes, pH, and swirling effect were evaluated according to the National Hemotherapy and Blood Bank Program criteria. Results: The platelet count had a mean of 6.66 ± 3.94 x 10¹°/µL, the platelet concentrates had a mean of 56.30 ± 6.22 mL, and all, without exception, had the presence of the Swirling phenomenon. The pH had a mean of 7.64 ± 0.15, while the leukocyte count had a mean of 4.22 ± 3.51 x 107/µL. Regarding compliance by the parameters evaluated, it was evident that the platelet and leukocyte count had moderate compliance rates of 43.6% and 24.1%, while the pH and swirling effect had rates of 100% in both cases. The total compliance rate was 54.9% (95% confidence interval: 46.0 to 63.5). Conclusions: The compliance rate of platelet concentrates is moderate, and it is necessary to implement a process of continuous quality improvement in the blood bank.

Los concentrados plaquetarios fueron obtenidos por el método de Buffy Coat y se evaluaron parámetros como el recuento de plaquetas y leucocitos residuales, pH y efecto swirling, según criterios del Programa Nacional de Hemoterapia y Bancos de Sangre. Resultados: El recuento de plaquetas tuvo una media de 6.66 ± 3.94 x1010/µL y los concentrados plaquetarios tuvieron una media de 56.30 ± 6.22 mL, y todos sin excepción tuvieron presencia de fenómeno Swirling. El pH tuvo una media de 7.64 ± 0.15, mientras que el recuento de leucocitos tuvo una media de 4.22 ± 3.51 x107/µL. En cuanto al cumplimiento por parámetro evaluado, se evidenció que el recuento de plaquetas y leucocitos tuvieron tasas de conformidad de 43.6% y 24.1%, mientras que el pH y efecto swirling tuvieron tasas del 100% en ambos casos. La tasa de conformidad total fue 54.9% (CI95%: 46.0 a 63.5). Conclusiones: La tasa de conformidad de los concentrados plaquetarios es moderada, y se requiere implementar un proceso de mejora continua de la calidad en el banco de sangre.

Patterns of red blood cell utilization: Harnessing electronic health records data from the Information Standard for Blood and Transplant (ISBT) 128 system within the Biologics Effectiveness and Safety (BEST) initiative.

BACKGROUND: Current hemovigilance methods generally rely on survey data or administrative claims data utilizing billing and revenue codes, each of which has limitations. We used electronic health records (EHR) linked to blood bank data to comprehensively characterize red blood cell (RBC) utilization patterns and trends in three healthcare systems participating in the U.S. Food and Drug Administration Center for Biologics Evaluation and Research Biologics Effectiveness and Safety (BEST) initiative. METHODS: We used Information Standard for Blood and Transplant (ISBT) 128 codes linked to EHR from three healthcare systems data sources to identify and quantify RBC-transfused individuals, RBC transfusion episodes, transfused RBC units, and processing methods per year during 2012-2018. RESULTS: There were 577,822 RBC units transfused among 112,705 patients comprising 345,373 transfusion episodes between 2012 and 2018. Utilization in terms of RBC units and patients increased slightly in one and decreased slightly in the other two healthcare facilities. About 90% of RBC-transfused patients had 1 (~46%) or 2-5 (~42%)transfusion episodes in 2018. Among the small proportion of patients with ≥12 transfusion episodes per year, approximately 60% of episodes included only one RBC unit. All facilities used leukocyte-reduced RBCs during the study period whereas irradiated RBC utilization patterns differed across facilities. DISCUSSION: ISBT 128 codes and EHRs were used to observe patterns of RBC transfusion and modification methods at the unit level and patient level in three healthcare systems participating in the BEST initiative. This study shows that the ISBT 128 coding system in an EHR environment provides a feasible source for hemovigilance activities.

Opportunities to improve feedback to reduce blood component wastage: Results of a national scheme evaluation.

BACKGROUND: Blood components are costly and scarce. The Blood Stocks Management Scheme (BSMS) was established in the United Kingdom (UK) to support hospital transfusion services and national blood services through collection, analysis, and monthly feedback of data on blood component inventory and wastage management. There is a growing evidence base on how best to deliver feedback for quality improvement. We assessed the quality and utility of the monthly BSMS component reports. METHODS: We assessed the content of BSMS reports issued in March 2023 against established criteria for effective feedback. Two researchers independently rated whether criteria spanning the five domains of goal setting, data collection, feedback content, feedback display and feedback delivery were fully, partially or not met. Disagreements were resolved through discussion. We conducted an online questionnaire survey of recipients of BSMS reports during March 2023 to assess their use of reports and seek suggestions for improvement. RESULTS: Five out of 20 criteria for effective feedback were fully met. Areas for improvement included placing more emphasis in the feedback on positive change, linking data and summary messages, and including specific suggestions for action. Respondents highlighted the value of benchmarked comparisons with other hospital transfusion services. CONCLUSION: There is scope for enhancing the effectiveness and utility of BSMS feedback reports and hence reducing wastage of blood components. This methodology for evaluation of feedback could be utilized to improve other areas of transfusion practice.

Hybrid cord blood banking in a private-public-partnership: Women's perspectives.

BACKGROUND: The increasing demand for umbilical cord blood (UCB) used in stem cell transplantation led to the establishment of cord blood (CB) banks worldwide. These include public foreign donor banks and private family-directed donor banks. Recently, our department has introduced a third banking model within a private-public-partnership. This hybrid banking allows for storage of family-directed CB units, while also getting Human leukocyte antigen (HLA)-typed and included in the national stem cell donor registry. So if the need arises, the HLA-compatible CB unit can be released to an unrelated recipient as a foreign donor stem cell graft. OBJECTIVES: The aim of this study was to evaluate women's perspectives on the different CB banking options as well as retrospective satisfaction with their decisions. METHODS: We performed a prospective survey study in postpartum women, using a validated questionnaire. RESULTS: A total of 157 women were included in this survey study; 68% of them decided to have their UCB stored or donated. Among those women, 25% of them opted for hybrid storage, 72% of respondents stored UCB publicly, and 3% decided for private family-directed storage. CONCLUSIONS: Our study shows the potential of hybrid banking as an attractive UCB storage option, as an alternative to family-directed banking rather than a substitute for public donation. Hybrid storage potentially combines advantages of family-directed banking as well as unrelated CB donation expanding the number of registered CB units available for transplantation and giving every pregnant woman the possibility to store UCB.
