An Updated Assessment of Safety Strategies for Platelet Blood Concentrates (PCs): A Short Review Article

Background: Platelet concentrates (PCs) are one of the most used blood components in blood banks due to their essential role in treating thrombocytopenia, and while viral transmission has been largely addressed, bacterial contamination of platelet concentrates (PCs) are still regarded as a crucial safety concern. Objective: This short review aimed to consolidate current knowledge on the strategies followed in blood banks to maximize the quality and shelf life of platelet concentrates (PCs). Different methods of each strategy were considered, focusing on outcomes related to approved and effective outcomes. Methods: The current study is based on PubMed, Wiley, and Web of Science databases to assess donor selection, bacterial screening, and pathogen reduction technologies utilized for PCs quality. All articles were collected until April 2024. Studies utilizing approved interventions and relevant hospital outcomes were inclusive. However, repetitive data and unapproved methods were among the exclusive criteria. Collected published manuscripts were reviewed. Results: The studies reviewed and referenced in this article consensus that pathogen reduction technologies (PRTs) utilizing Ultraviolet rays (UV) was found to be effective in eliminating various bacterial contamination. Furthermore, the need for donor and bacterial screening is still essential and could not be overlooked. Pathogen reduction technologies (PRTs) remain important and valid despite studies suggesting the reduced platelet concentrates (PCs) quality and the need for frequent transmission of PCs. Some studies even foresee pathogen reduction technologies (PRTs) as replacing the cultural bacterial detection methods. Conclusion:We conclude that preventing bacterial contamination in platelet concentrates (PCs) requires a multifaceted approach. However, future research should focus on optimizing these strategies while minimizing their potential adverse effects on platelet function and safet

Ferroptosis regulates hemolysis in stored murine and human red blood cells.

Red blood cell (RBC) metabolism regulates hemolysis during aging in vivo and in the blood bank. However, the genetic underpinnings of RBC metabolic heterogeneity and extravascular hemolysis at population scale are incompletely understood. Based on the breeding of 8 founder strains with extreme genetic diversity, the Jackson laboratory diversity outbred population can capture the impact of genetic heterogeneity in like fashion to population-based studies. RBCs from 350 outbred mice, either fresh or stored for 7 days, were tested for post-transfusion recovery, as well as metabolomics and lipidomics analyses. Metabolite and lipid Quantitative Trait Loci (QTL) mapped >400 gene-metabolite associations, which we collated into an online interactive portal. Relevant to RBC storage, we identified a QTL hotspot on chromosome 1, mapping on the region coding for the ferrireductase Steap3, a transcriptional target to p53. Steap3 regulated post-transfusion recovery, contributing to a ferroptosis-like process of lipid peroxidation, as validated via genetic manipulation in mice. Translational validation of murine findings in humans, STEAP3 polymorphisms were associated with RBC iron content, lipid peroxidation and in vitro hemolysis in 13,091 blood donors from the Recipient Epidemiology and Donor Evaluation Study. QTL analyses in humans identified a network of gene products (FADS1/2, EPHX2, LPCAT3, SLC22A16, G6PD, ELOVL, PLA2G6) associated with lower levels of oxylipins. These polymorphisms were prevalent in donors of African descent and were linked to allele frequency of hemolysis-linked polymorphisms for Steap3 or p53. These genetic variants were also associated with lower hemoglobin increments in thousands of single-unit transfusion recipients from the vein-to-vein database.

NCOG-28. SERUM PROTEIN BIOMARKERS LINKED TO NEURODEGENERATIVE PROCESSES ARE ELEVATED IN GLIOMA PATIENTS AND ASSOCIATED WITH SEVERITY OF NEUROLOGIC SYMPTOMS

Abstract BACKGROUND Glioma patients frequently report neurologic symptoms, adding to the complexity of cancer management and negatively impacting quality of life. However, mechanisms associated with the development of neurologic symptoms in glioma patients remain unclear. Pathological changes in the brain of glioma patients might result in elevated peripheral blood levels of proteins previously linked to central nervous system (CNS) damage and neurodegeneration, including neurofilament light chain (NfL), tau, and glial fibrillary acidic protein (GFAP). Here, we tested the hypothesis that the circulating levels of these proteins in blood are elevated in glioma patients and associated with the severity of neurologic symptoms. METHODS Patients (n=73) were enrolled in a natural history study (NCT02851706, PI T. Armstrong). Healthy subjects (n=39) were recruited by the National Institutes of Health Clinical Center Blood Bank. Neurologic symptom severity and walking interference were assessed using MD Anderson Symptom Inventory-Brain Tumor (MDASI-BT). Serum proteins were analyzed using ultrasensitive assays (Meso Scale Discovery). RESULTS Participants were predominantly white (patients 74%, healthy subjects 67%) and male (patients 58%, healthy subjects 54%). The median age was 44 (range=24,74) for patients and 49 (range=19,78) for healthy volunteers. No significant differences in age, sex, or race were observed between patients and healthy subjects. Serum levels of NfL (p<0.0001), GFAP (p<0.0001), and tau (p<0.0001) were higher in glioma patients when compared to healthy subjects. Patients with walking interference had higher levels of GFAP (p=0.003), NfL (p=0.003), and tau (p=0.004), and those who reported numbness had higher levels of GFAP (p=0.012). CONCLUSIONS These findings suggest that serum levels of protein markers of neurodegeneration are elevated in glioma patients and associated with the presence of neurologic symptoms. Blood-based biomarkers have the potential to shed light on the mechanisms underlying symptoms and offer a non-invasive alternative for monitoring CNS damage that impact patient outcomes.

Longitudinal Analysis of Binding Antibody Levels Against 39 Human Adenovirus Types in Sera from 60 Regular Blood Donors from Greifswald, Germany, over 5 Years from 2018 to 2022

Adenoviruses are important human pathogens that are widespread and mainly associated with respiratory and gastrointestinal infections. In a previous study on human adenovirus (HAdV) seroprevalence, we observed reduced binding antibody levels against a range of HAdV types in sera collected from students in 2021 compared to sera collected before the SARS-CoV-2 pandemic. In this follow-up study, we wanted to verify this observation in a cohort of regular blood donors for whom serial samples were available. Therefore, HAdV-specific binding antibody levels were analyzed in sera collected over a 5-year period from 2018 to 2022 in a cohort of 60 regular donors to the blood bank of the University Hospital in Greifswald, Germany. Using ELISA-based assays, we quantified the binding antibody responses against 39 HAdV types. On the cohort level, we found largely stable antibody levels over the analyzed time period, with the highest antibody responses against HAdV-C1, -D25, -D26, -E4, -D10, -D27, -C5, -D75, -C2, and -C6. Only minor but significant reductions in comparison to the first serum samples from 2018 were detected for antibody levels in 2021 and 2022 against the low-prevalent types HAdV-A31, -D8, -D20, -D37, -D65, and -D69. On the other hand, we detected fluctuations in antibody levels on the individual level, with strong increases in antibody levels indicative of novel antigen contact. Interestingly, we frequently found simultaneous changes in antibody responses against multiple HAdV types, resulting in strong correlations of antibody responses against distinct clusters of HAdVs suggesting extensive cross-reactivity of HAdV-specific antibodies. To our knowledge, this is the first study of antibodies against a broad range of HAdV types in serum samples collected from a cohort of individuals over a prolonged period, and our data provide important insight into the long-term stability of HAdV-specific antibody levels. In this cohort of regular blood donors, we did not observe any major impact of the SARS-CoV-2 pandemic on HAdV immunity. Correlations of changes in antibody levels against different types indicate cross-reactivity of HAdV-specific antibodies that are important to consider for HAdV vector development. Our data also reveal possible candidates for future development of HAdV-based vectors.

What are the minimal criteria of goal-directed perfusion (GDP) in adult cardiac surgery?

Introduction: Nowadays, many cardiac surgery teams are adopting the goal-directed perfusion (GDP) strategy in their practice to maintain optimal perfusion during cardiac surgeries and improve patient outcomes. Furthermore, it plays an indispensable role as a quality control tool to monitor both perfusionists’ practice and equipment (in addition to disposables used in the surgery. Objectives: To identify the role and the elements of GDP that facilitate better surgical outcomes. In addition, to compare between GDP and the traditional conventional perfusion strategy (CP) in terms of perfusion adequacy and surgical outcomes. Finally, to recognize challenges that may prevent the effective application of GDP and finding possible applicable solutions. Methods: A systematic literature review was conducted from three different databases PubMed, SpringerLink, and ScienceDirect. The selected studies were in English from the USA and Europe with a time frame starting from 2005. Results: The findings highlight the crucial role of the GDP strategy in protecting and preserving end-organ function after on-bypass cardiac surgery procedures. Furthermore, a clear understanding of the GDP implementation component and criteria was obtained. Alternatively, a satisfactory GDP level can be achieved by the optimal utilization of available resources. Discussion: Dismantling the GDP strategy into practically recognized components to ease the implementation at different levels of perfusion practice. Conclusion: The GDP approach involves the intensive monitoring of respiratory-related parameters to enhance surgical outcomes. The process includes blood preservation, optimal flow and intraoperative parameters management. Monitoring is the key element of GDP, which can be applied by using the sophisticated technology or the proper use of existing resources to develop protocols within the international guidelines and recommendations. Achieving an optimal perfusion requires concerted efforts of organizational, safety, and practical measurements.

Trends in new hepatitis C virus infections among repeat blood donors - Georgia, 2017-2023.

Blood donor cohorts are an underappreciated resource for surveillance and public health programming for infectious diseases. The incidence of hepatitis C virus (HCV) infection was evaluated in repeat blood donors in Georgia. Using data from the national hepatitis C screening registry, we calculated overall hepatitis C incidence for 2017-2023 and annual incidence during 2017-2022 among adults who donated blood at least twice and had a nonreactive HCV antibody (anti-HCV) test result upon first screening and a subsequent anti-HCV test conducted in any location. Rates of anti-HCV seroconversion and current infection were calculated by year, sex, age group, and location of last HCV screening and expressed per 100,000 person-years (PY). Of 101,443 blood donors with ≥2 anti-HCV results,775 (0.8%) seroconverted to anti-HCV reactive, of whom 403 (52.0%) had current infection. Incidence of anti-HCV seroconversion decreased from 408 per 100,000 PY in 2017 to 218 per 100,000 PY in 2022 and incidence of infection decreased from 172 per 100,000 PY in 2017 to 118 per 100,000 PY in 2022. Males, persons aged 18-39 years, and people last tested for HCV in prisons had the highest incidence rates for anti-HCV seroconversion and HCV infection, while persons last screened in blood banks and during antenatal care had the lowest. Despite the observed decline, incidence of HCV infection among repeat blood donors remains high in specific subgroups. Hepatitis C prevention, screening and treatment interventions need to particularly focus on incarcerated populations and young adults in Georgia.

Developing a veno-venous extracorporeal membrane oxygenation program during the COVID-19 pandemic: don’t forget to notify the blood bank

ObjectivesDuring the SARS-CoV-2 pandemic, there has been significant increased use of vvECMO as rescue therapy. Patients with COVID-19 as anticoagulation is needed for vvECMO support, may develop bleeding complications requiring an increased number of RBC transfusions. We would like to report the RBC transfusion needs following the implementation of an ECMO program. Data on blood usage in this population is important in view of the decline in donations due to the pandemic.Study Design and Methods: We analyzed data on RBC transfusions in patients who required vvECMO for COVID-19 related ARDS in a Belgian ICU from March 2020 to March 2022. The primary end point was RBC transfusion requirements. and the relationship to outcome. We also analyzed the evolution of this requirement during the four waves. ResultsWe admitted 538 patients for hypoxemic ARDS due to COVID-19. Sixty patients (11%) required vvECMO, of whom 27 (45%) died. Forty-seven (78 %) of the vvECMO patients were transfused a total of 403 packed RBC units.. Sites of hemorrhagic complications were ECMO cannulation sites and lungs. RBC transfusion per patient per day on vvECMO was 0.50 [0.30-0.67] units. There were no differences in hemorrhagic complications in vvECMO survivors and non-survivors.The percentage of vvECMO patients receiving a RBC transfusion increased slightly during the last COVID-19 wave, with 92 % of patients transfused. ConclusionsvvECMO program is associated with a major need for RBC transfusions. These data are important when blood availability is decreased due to a pandemic and illustrates the need for studies on optimizing blood management including therapeutic anticoagulation target, threshold for RBC transfusion or alternatives to RBC transfusion.

Sterility of cord blood units: Evaluation of the collection, preparation and conservation process with a view to establishing a bank of stem cells from cord blood at the Biological Resources Center of the Institut Pasteur de Côte d’Ivoire (2024)

Introduction: Cord blood stem cells are used as an alternative to bone marrow and peripheral blood cell transplantation. For this purpose, cord blood banks have been established worldwide for the collection and cryopreservation of cord blood units. These banks must implement rigorous protocols to ensure the microbiological safety of grafts. The aim of this study is to evaluate the process of selecting mothers and collecting and processing these samples developed for this purpose. Methodology: Pregnant women were enrolled in the study on the basis of selection criteria. Maternal blood and cord blood samples were collected by the in utero method. Serological analyses of maternal blood for the detection of vertically transmitted infections and microbiological examinations of cord blood units were carried out. Results: 31 women out of 46 (68.4%) were enrolled. All had negative serology for the targeted pathogens. Similarly, microbiology revealed no microbial contamination of the cord blood units. Conclusion: This work demonstrates that the procedures for selecting mothers and processing implementations are effective in ensuring the microbiological safety of cord blood units and could be suggested in the context of banking cord blood stem cells at the Institut Pasteur de Côte d’Ivoire.

Knowledge, Attitudes, and Practices of Pregnant Women and Hospital Staff Regarding Umbilical Cord Blood Banking: Systematic Review and Meta-Analysis.

The aim of this study is to assess the knowledge, attitudes, and practices of pregnant women and hospital staff regarding umbilical cord blood (UCB) donation and storage to understand its limitations in clinical practice. MEDLINE, Scopus, LILACS, EMBASE, Scielo.br, and PROSPERO were searched from inception to 30 November 2023 with no geographic or language restrictions. The study eligibility criteria included cross-sectional studies that interviewed pregnant women and/or hospital staff about their knowledge, attitudes, and practices regarding private or public storage. A random-effects restricted maximum-likelihood model with Freeman-Tukey Double arcsine transformation meta-analysis was carried out to calculate the pooled estimates. MOOSE guidelines were followed. STATA 14.1 was used for statistical analysis. The Newcastle-Ottawa Scale and ROBINS-I tool were used for quality and risk of bias assessments. In total, 19 studies providing data for 19,904 pregnant women and 1245 hospital staff members were included. Pooled pregnant women awareness was 61% ((95% CI 0.60 to 0.62), I2 = 0%, τ2 = 0.00, Q = 11.0 (p = 0.950)), and 61% for hospital staff (95% CI 0.58 to 0.64), I2 = 0%, τ2 = 0.00, Q = 4.00 (p = 0.310)). In total, 57% ((95% CI 0.56 to 0.58), I2 = 0, τ2 = 0.00, Q = 4.00 (p = 0.320)) of pregnant women had a positive attitude about UCB, while 34% ((95% CI 0.32 to 0.36), I2 = 0%, τ2 = 0.00, Q = 4.00 (p = 0.310)) were in favor of donating UCB for research and 65% ((95% CI 0.63 to 0.66), I2 = 0%, τ2 = 0.00, Q = 4.0 (p = 0.350)) were planning UCB storage. A significant (p < 0.001) preference for public relative to private banking (51% ([95% CI 0.49 to 0.54], I2 = 0%, τ2 = 0.00, Q = 4.0 (p = 0.310)) vs. 12% ([95% CI 0.10 to 0.13], I2 = 0%, τ2 = 0.00, Q = 4.0 (p = 0.300))) was noted for pregnant women. The same was retrievable for professionals (84% ([95% CI 0.79 to 0.88], I2 = 0%, τ2 = 0.00, Q = 2.0 (p = 0.110)) vs. 6% ([95% CI 0.03 to 0.09], I2 = 0%, τ2 = 0.00, Q = 1.0 (p = 0.070); p < 0.001)). Despite these efforts, lack of knowledge and positive attitudes about UCB banking remain, emphasizing the need for increasing educational programs on the subject.

An ecosystem of interconnected technologies to increase efficiencies in blood establishments: The example of the Blood and Tissue Bank of Aragón, Spain.

Blood establishments face environmental, financial, demographic and societal challenges that may impair sustainable blood supply to patients. This study presents the technologies (devices and software) assembled in a global ecosystem implemented by the Blood and Tissue Bank of Aragón (BTBA), Spain, over the last decade to overcome these challenges. Descriptive yearly activity data (2013-2023) of BTBA were retrospectively collected to evaluate the impact of different technologies on blood processing efficiency, focusing on the production of blood components (red blood cell concentrates [RCCs], platelet concentrates [PCs]) and plasma. Operator satisfaction about the technologies introduced in daily routine work was also monitored. Between 2013 and 2023, the annual production decreased by 16.0% for RCCs and increased by 13.3% for PCs. From 2020, all PCs were treated with pathogen reduction technology, and no inventory stock-out was reported. The lowest PC expiry rate (0.2%) was observed after the implementation of the software for blood processing and PC stock management. The deployment of this software also improved plasma recovery: on average, an extra plasma volume of 9 mL was collected per donation in 2023 compared to 2015. A survey confirmed staff satisfaction. The progressive implementation of automated and software-based solutions was key to increasing efficiencies in BTBA. This enabled the optimization of blood processing by maximizing productivity, enhancing traceability, reducing overproduction and wastage and increasing the yield of recovered plasma, while ensuring blood product safety and staff satisfaction.

Preserving Stem Cells for Potential Use in Future Reparative Medicine

With its enormous potential for regenerative medicine and therapeutic applications, stem cell preservation represents a major breakthrough in biomedical science. Stem cells are gathered, processed, and stored under carefully monitored circumstances in order to preserve their viability for potential use in the future. Because they may differentiate into a variety of cell types, stem cells—especially those derived from sources like umbilical cord blood—are essential for both therapeutic and research uses. An essential function of cord blood banking is to offer a plentiful supply of immune system cells that may be stored for potential future therapeutic applications. Immunological deficits, osteoarthritis, Parkinson's disease, and heart failure are just a few of the conditions for which stem cell treatments have shown promise. Notwithstanding the promise, there remain obstacles such immunological rejection and the need for more research to fully comprehend the development and functionality of stem cells. It is essential for the general public to be informed about stem cell treatments and cord blood banking in order for expectant parents to make well-informed decisions. Future advancements in the subject depend heavily on resolving ethical issues and enhancing the effectiveness of stem cell-based therapies. To fully realise the promise of stem cell preservation in conventional medicine, more research, creativity, and international cooperation are required.

The online blood bank management web application is a useful tool which can be used in different areas of the healthcare setting such as laboratories, clinics and even emergency situations where there is a need for blood units. Because of streamlining all the operational procedures that are needed for blood donation as well as for its purchase, this system is in fact a one stop center for the management of blood operations. Important facts about the blood groups and their site cannot be missed out by users of our web. This grips up reflection ensures that in case of emergency any one even who is ready to donate or any representative of the authorized centers can quickly search and get the required blood groups. One of the main objectives of our system is also to minimize the concerns which people usually have when they are in need of blood due to its lack. Through focusing on blood systems that prevent breakdowns in ordering and using the blood, we will construct efficient systems that, together, eliminate the problems encountered in blood purchasing and usage.

Safety of Hepatitis B Virus Screening in Blood Donors from the Hospital Foundation of Hematology and Hemotherapy of the State of Amazonas (HEMOAM) in the Brazilian Amazon

Background: Hepatitis B is an infectious disease of worldwide importance and of great interest to transfusion medicine. The Amazon region has areas of high endemicity, outlining a worrying scenario for transfusion and epidemiological safety. Objective: To analyze the profiles of serological and molecular markers for HBV of blood donors from HEMOAM. Methods: Blood donors with different patterns of reactivity in serological and molecular screening for HBV were tested for viral load by the qPCR method at the reference center for liver diseases in the state of Amazonas. Results: A total of 230,591 donors were tested, with 3104 (1.34%) found reactive for HBV and 2790 (89.9%) found reactive for isolated anti-HBc. Viral load was not detected in 100% of donors reactive only to HBsAg, while 100% of donors with positive anti-HBc and positive HBsAg or HBV NAT demonstrated a detectable viral load. We also detected one case of occult hepatitis B (0.03%) only with reactive HBV NAT and five donors (0.2%) with positive anti-HBc and HBV NAT. Conclusions: With this result, the great importance of the anti-HBc test for the unsuitability of blood donors was verified, as well as the fundamental introduction of the HBV NAT test in screening for hepatitis B in Brazilian blood banks, as this was the only way to detect the viral infection burden in asymptomatic donors who previously would not be treated, which contributed to the maintenance of the endemicity of hepatitis B in the Brazilian Amazon.

The impact of institutional measures on optimal use of intravenous immunoglobulin.

Intravenous immunoglobulin (IVIG) shortage represents an emerging issue in transfusion medicine. Limited data are available to determine effective strategies for optimal use. The objective of this retrospective observational study was to determine the impact of institutional measures on IVIG use at a large academic center. IVIG infusions from November 26, 2018 to September 25, 2022 were categorized according to their appropriateness (Recommended, Option of treatment, or Unrecommended), based on provincial guidelines, and separated into three phases: Reference, Transition, and Post-Implementation phases, the latter following the adoption of restrictive measures, including mandatory standardized order forms, a blood bank gatekeeping strategy, and the creation of a stewardship committee. A total of 5431 IVIG infusions were administered to 544 patients, accounting for 295,033 g. The most common indication categories were neurology (30.4%), immunology (29.0%), and hematology (17.4%). From Reference to Post-Implementation phase, IVIG infusions decreased from 2275 to 2000 with unrecommended indications dropping from 9.5% to 7.4% (p = 0.01), and a global reduction of 23.0% (from 131,163 g to 100,936 g of IVIG). Decrease in chronic immunomodulation accounted for 48.3% of total reduction (14,610 g of 30,227 g), whereas single-use immunomodulation, 40.5% (12,237 g of 30,227 g). Moreover, an absolute reduction of 16.9% was observed in orders exceeding the recommended doses (20.8% to 3.9%; p < 0.0001). Together, the unrecommended and excessive IVIG doses decreased from 19,975 g (15.2%) to 6670 g (6.6%). A global reduction in IVIG use and a preferential decrease in the unrecommended orders were observed, most likely attributable to the bundle of restrictive strategies implemented.

Transfusion-Related Acute Lung Injury

Transfusion-Related Acute Lung Injury is one of the most vital forthcoming risks that need to be addressed, assessed, diagnosed and treated. Blood transfusion save lives, but the side effects of transfusion can be really adverse and concerning. Blood transfusion helps the patient recover from severe blood loss that might lead to severe complications like cardiogenic or hypovolemic shock. Over the years, the health care industry is working on reducing the possible risk and complications of blood transfusion. Worldwide trainings are provided on safe blood transfusion practices. Blood banks are verified with legal authority and inspections are done every now and then. Transfusion-Related Acute Lung Injury is the upcoming concerning issue that needs to be familiar with all health care workers especially nurses since they are the one who keep a close monitoring of patient during the blood transfusion process. Furthermore intervention can be planned accordingly to help manage Transfusion-Related Acute Lung Injury better and treat the symptoms as soon as possible.

Present study aimed to assess the use of blood and blood components issued by blood bank and indication for selection of specific blood products. The present cross sectional observational time bound study was conducted at Father Muller Medical College &amp; Hospital, which included all the patients to whom the whole or blood component are issued from blood between Jan 2016 to Jan 2020. All the units of blood and blood components issued to outside hospitals and institutions were excluded. A total of 20000 components were dispatched to 5002 patients request for the blood components from the blood bank, 2968 were males and 2032 were female patients (male to female ratio of 1.46:1). Highest request for blood components for transfusion was received from Medicine department and allied with 6063 units, followed with various Intensive care units (4477 units), oncology department (5729 units), OBG (1841 units), orthopaedics (1248 units) and surgery (453 units). The most common diagnosis for patients requiring blood components was haematological causes or Bleeding followed by elective surgery. Auditing the use of blood, its components and indications for their use by the various departments of the hospital has helped to finding the trend of number of blood.

Bacterial Contamination of Donor Blood Units in a Ghanaian Blood Bank: A Critical Concern for Transfusion Safety

Abstract Introduction/Objective Background: Blood transfusions, while life-saving, pose a significant risk to patient safety, with transfusion-associated bacterial sepsis emerging as a persistent and potentially fatal threat. The prevalence and severity of bacterial contamination in donor blood units necessitate regular surveillance to ensure safe and effective transfusion therapy. Aim This study aimed to identify and assess the susceptibility of bacterial isolates in whole blood donor units at the blood bank of Cape Coast Teaching Hospital in the Central Region of Ghana. Methods/Case Report Method(s): One hundred and three (103) units of stored whole blood units, declared safe for transfusion (testing negative for HIV I&amp;II, HBsAg, HCV, and syphilis), were inoculated into Brain Heart Infusion Broth and incubated for 24 hours. The inoculated broths were then cultured on MacConkey agar (MAC), Chocolate agar (CHOC), and Blood agar. Gram-negative and Gram-positive isolates were identified using standard biochemical tests. Antimicrobial susceptibility testing was performed using the disc diffusion method. Results (if a Case Study enter NA) Results: Of the 103 donor blood units tested, 33 (32.03%) were found to have bacterial isolates. Gram-positive organisms accounted for 67.14% of the isolates, including Coagulase negative Staphylococcus, Bacillus spp, and S. aureus. Gram-negative bacteria constituted 32.86% of the isolates, with Citrobacter freundii, Serratia marcescens, E. coli, and Providencia stuartii identified. Notably, 62.9% of the bacterial isolates were skin commensals, while 25.7% were of enteric origin and 11.4% were of nosocomial origin. Resistance to commonly used antibiotics varied among isolates, with Coagulase-negative Staphylococcus exhibiting resistance to amoxicillin (92.86%) and erythromycin (76.19%), while Citrobacter freundii showed resistance to levofloxacin (75.00%) and ofloxacin (75.00%). Conclusion Conclusion(s): The high incidence of bacterial contamination in donor blood units highlights the need for improved phlebotomy procedures and decontamination practices at blood banks in Ghana to reduce the risk of sepsis in transfusion recipients. Furthermore, this study provides valuable information regarding antibiotic resistance patterns in bacterial isolates, emphasizing the importance of antibiotic stewardship in Ghana. In conclusion, this study underscores the urgency of addressing bacterial contamination in donor blood units in Ghanaian blood banks to enhance transfusion safety.
