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 15/22 countries in the region. 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, 87.5%) 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.
To overcome the shortage of blood to treat obstetric hemorrhage, the first step is to evaluate the demand and supply gap by acquiring comprehensive data on the current status of the blood supply and the prevalence of obstetric hemorrhage in Ethiopia. Subsequent steps would include the implementation of transfusion policies, the optimization of whole blood collection, ensuring quality-assured testing of donated blood, and the implementation of transfusion guidelines for the appropriate use of blood products. Strategies for long-term, viable solutions to maintain an adequate blood supply should be simultaneously developed.
OBJECTIVE: The current study was conducted to evaluate the performance and screening effectiveness of commercially available rapid screening kits in comparison with chemiluminescence immunoassay (CLIA) and polymerase chain reaction (PCR). MATERIALS AND METHODS: This single-center, cross-sectional study was conducted at the Department of Pathology and Blood Transfusion Services, Shaheed Zulfiqar Ali Bhutto Medical University, PIMS, Islamabad, from January to April 2019. A total of 10 commercially available immunochromatographic test (ICT) devices and one CLIA kit (LIAISON XL) were tested for their sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy using 100 positive and 100 negative samples each for HBV and HCV, respectively. RESULTS: The sensitivities and specificities of ICT kits for hepatitis B surface antigen were 65% and 70% (Hightop), 67% and 85% (RightSign), 62% and 73% (Wondfo), 70% and 80% (Accu-Chek), 68% and 77% (Fastep), 73% and 85% (Abon), 77% and 83% (ImmuMed), 80% and 90% (Insta-Answer), 67% and 81% (BioCheck), and 72% and 83% CTK Biotech, respectively. Similarly, the sensitivities and specificities of different ICT kits for HCV were 69% and 80% (Hightop), 76% and 83% (RightSign), 69% and 81% (Wondfo), 78% and 79% (Accu-Check), 68% and 68% (Fastep), 63% and 73% (Abon), 71% and 70% (ImmuMed), 79% and 68% (Insta-Answer), 62% and 66% (BioChek), and 69% and 78% CTK Biotech, respectively. The sensitivity and specificity of Diasorin Liaison Murex assay for both HBV and HCV were found to be 100% when compared with PCR. The PPV, NPV and Accuracy were determined accordingly.CONCLUSION: Rapid testing ICT devices for both HBV and HCV available in Pakistan were found to have a variable degree of sensitivity and specificity when compared with CLIA and PCR. Comparatively expensive but quality methods are more reliable as compared to rapid devices.
Background: Availability and safety of blood transfusion is a major concern in countries affected by humanitarian emergencies. These emergencies increase demand for blood transfusion and make its delivery challenging and complex. Nevertheless, there is a lack of information on emergency preparedness and response capacity of blood transfusion services and on the challenges in meeting patients' needs. Aims: To assess availability and safety of blood transfusion during humanitarian emergencies. Methods: We searched PubMed and Index Medicus for the World Health Organization Eastern Mediterranean Region for data on availability and safety of blood transfusion during humanitarian emergencies. We also gathered information through a survey and during a regional consultation in Tunisia. Results: We found 24 publications on disaster from 5 countries in the Region and 16 publications on disaster preparedness and blood transfusion in casualties and severe trauma outside the Region. However, none dealt with availability and safety of blood transfusion during humanitarian emergencies. Armed conflicts and terrorism, flooding and earthquakes are the most frequent emergencies with 10-85% of the injured requiring blood transfusion. There are gaps in emergency preparedness and response, including human resources, transport and cold chain, supply of consumables and maintenance of equipment, power supply, and finances. Conclusions: There is a need to integrate blood transfusion services in the overall national emergency preparedness and response, and provide assistance to affected countries to address identified gaps. Recommendations for individual countries need to be tailor made, along the lines of the regional strategic framework for blood safety and availability.
