Over90% of recipients of HIV infected blood will seroconvert. In the Region 368 cases were due to transmission through blood or blood products. With establishment of HIV screening facilities, the proportion of AIDS cases due to blood transmission has decreased. AIDS due to blood transmission will continue to occur due to the time lag between the occurrence of HIV infection and appearance of AIDS. HIV seroprevalence among recipients of multiple blood transfusions decreased from 270 per 10 000 in 1987-89 to 7 per 10 000 in 1995. Effective methods are available for prevention of HIV transmission through blood, but antigen and PCR tests are expensive and not recommended for screening of blood donations in developing countries

The under-representation of women in blood donation can lead to blood shortages. We aimed to determine the factors, which encourage or impede blood donations in women. The findings can help us in designing effective recruitment strategies that could encourage women to donate blood to cover the patients’ needs. This cross-sectional study was conducted in Shiraz, Iran, from the 1st of January 2017 to the 1st of August 2017 on women aged 18–60 years old. The demographic characteristics of the participants, the reasons that motivate blood donors and the factors that discourage non-donors were surveyed. Reasons for lapses in donors were also mentioned. The most frequent reasons for blood donation were altruistic causes (94.4%), moral and personal obligations (89.1%), the feeling of responsibility (82.7%), and awareness of the positive effects on their health (77.4%). The most common deterrents in non-donors were fear of developing anemia (68.4%) or weakness and dizziness (66%), unsuitability due to certain medical conditions (62.4%), and lack of a situation in which they were asked to donate blood (61.8%). Although altruistic reasons are the chief motivating factors for women to donate blood, the overall female contribution in blood donation remains low. Therefore, it is necessary to take measures aiming at informing women about the importance of blood donation and to reduce fears based on misinformation. Confidence in the blood donation organization must be a major consideration in future recruitment strategies to reassure women about the safety of blood donation.

PurposeBlood donation knowledge of healthy young students is crucial to donate blood voluntarily and regularly in long-term. This study aimed to determine the influencing factors on the blood donation knowledge, to identify gaps of blood donation knowledge and reasons for not donating blood among university and college students in Yangon, Myanmar.Design/methodology/approachCross-section survey (May 2019) was conducted in students of Yangon Technological University (YTU) and National Management Degree College (NMDC) with the use of quota and convenience sampling method. The questionnaires covered sociodemographic characteristics, blood donation knowledge and reasons for not donating blood.FindingsTotal 320 students (129 males and 191 females) with age of 18 to 23 years old participated. Previous blood donation had statistically significant influence on blood donation knowledge scores (ß = 0.396, p Originality/valueBlood donations programs should extend awareness-raising programs in academic society and population at large. Raising awareness should focus on the knowledge gaps such as donor eligibility, interval of blood donations, TTIs and benefits of donating blood to recipients.

The starting point of this study is based on a ground observation in Tunisia: The unsustainable blood donations and the shortage of clinical blood in some periods of the year (i.e. holidays; covid-19). This observation is also avowed in over the world. The present study extends the theory of planned behavior (TPB) by incorporating relevant variables from Self-determination Theory (SDT). The latter suggests that individuals persist with a behavior when they are internally motivated than externally motivated. Online survey was administrated to assess TPB constructs (attitudes, social norms, perceived behavioral control (PBC), personal moral) and two of SDT factors (autonomous and controlled). 321 donors responded to the questionnaire. Results revealed that effects of autonomous and controlled motivation on behavioral intention were mediated by attitude, PBC as well as moral norms. This paper proposes practical recommendations to social marketing designers to better retain blood donors.

Objectives of this study were to analyze characteristics influencing blood donation status, to identify anxieties and reasons for (non-)blood donation, and potential channels for future blood donation campaigns. A random population from Germany was interviewed using the online survey tool SoSci Survey. The access link to the questionnaire was distributed via snowball system and the Bavarian Red Cross. Statistical analysis was performed to identify factors influencing blood donation status. A total of 682 participants (27.3% blood donors) with a mean age of 33.4 and a standard deviation (SD) of 12.0 years were included into the analysis. Strongest factor associated with being blood donor was having a blood donor within family and friends (Odds ratio [OR]: 5.05 [95% confidence interval [95% CI]: 2.63; 9.70]; p≤0.001), whereas having anxiety related to blood donation was the strongest factor for being non-blood donor (OR: 0.11 [95% CI: 0.05; 0.21] p≤0.001). Other factors significantly influencing blood donor status were age, health-related quality of life, knowledge on blood donation, being an organ donor and having pre-conditions. Main anxieties avoiding blood donation were fear of physical consequences, and fear of the injection needle. Most frequently mentioned channels which should be used for blood donation campaigns were Instagram and free TV. Involving blood donors into campaigns to recruit new blood donors from their personal environment and to focus campaign content on physical benefits of blood donations might help to recruit new blood donors. In addition, running campaigns stronger on channels such as Instagram might increase their scope.

Objectives To estimate the number of actually Severe acute respiratory syndrome Coronavirus‐2 (SARS‐CoV‐2) infected blood donors applying a statistical forecasting model. Background Following the outbreak of the SARS‐CoV‐2 epidemic, a drop in blood donation has been observed. It is crucial to determine the actual number of potential SARS‐CoV‐2‐positive donors to define the measures and ensure adequate blood supply. Methods The cumulative incidence of SARS‐CoV‐2 positivity, calculated on the general population, was applied to the donor population by estimating the number of positive subjects. The calculation model was validated by the linear interpolation method. The number of blood units actually discarded based on post‐donation information was also taken into account. Results Three months after the outbreak, 5322 donors were estimated to be positive for SARS‐CoV‐2 and were therefore potentially excluded from donation. A total of units of blood components were discarded following post donation information. The estimated number of donors deceased (180) and the number of clinically recovered individuals in the same period was also considered. Conclusion This forecasting model can be used to obtain information on blood donors' involvement during future SARS‐CoV‐2 outbreaks, especially in case of changes concerning epidemiology, incidence by age bracket and geographical distribution and also for new outbreaks of emerging viruses.

The course of the coronavirus disease (COVID-19) pandemic has significantly affected the healthcare systems in multiple ways, the programs of control and the management of patients with other infectious diseases as well as with chronic and acute non-communicable diseases, including those conditions requiring blood transfusions. Blood donations have been decreasing over time in multiple countries with their expected consequences. Although the spread of SARS-CoV-2 has not been detected via blood transfusion, the increasing fear and anxiety among communities have led to a substantial decrease in blood donations. Several research groups have raised concerns about the consequences associated with the scarcity of blood. However, it is critical to understand the underlying causes of the sharp decline in blood donations, as well as the consequences. Hence, we discuss the impact of blood scarcity at the blood banks during the COVID-19 pandemic as well as strategies to promote blood donations, given the experience in some countries with this situation. © 2021 The Author(s).

Background Brazilian blood banks encourage donors to report postdonation information (PDI) regarding conditions that would lead to deferral in an attempt to retrieve distributed nonconforming blood. Objectives This study evaluated the profile of donors reporting PDI, the impact on transfusion safety, and the possible impact on the discard of blood products. Subjects and methods We analyzed 115 consecutive PDIs between May 2014 and July 2015, a period comprising two dengue-like syndrome (DLS) outbreaks. Results These PDIs accounted for 87,780 blood donations. The average time for PDIs since donation was 4 (0-23) days and 190 blood components were discarded. DLS accounted for 21.7% of the PDIs analyzed; 11 of the 23 samples tested were nucleic acid test (NAT) positive for dengue and 2 positive for Zika virus (ZIKV). Six of these PDIs were reported after blood components have been transfused: After NAT testing, one of these recipients was diagnosed with dengue and another one with ZIKV infection, both possible transfusions transmitted but without clinical consequences. Conclusion The high number of recovered blood components due to PDI suggests that PDI remains a great ally in the fight against transfusion-transmitted infections and may be particularly useful during outbreaks of emerging potentially blood-borne pathogens.

Background: Malaria is a mosquito-borne infectious disease caused by protozoan parasites of the genus Plasmodium. As migration of populations from endemic areas to Europe and overseas recreational travel to endemic regions increase, there is also a growing risk of transfusion-transmitted tropical diseases by blood components. Material and Methods: In the present study two routine Plasmodium spp. ELISA (CAPTIA™ Malaria EIA, Trinity Biotech, and Malaria EIA, BioRad) were compared with a new commercial ELISA (ELISA IgG, EUROIMMUN). From December 1, 2015 until November 30, 2016, 1,096 plasma samples from blood donors with a potential risk of malaria infection were collected at two blood transfusion centres in Germany and Switzerland. Results: The samples were tested comparatively with the ELISA from EUROIMMUN and the routine test used at the respective centre. Thirty-four of 595 (5.7%) tested blood samples from centre 1 and 49 of 501 (9.8%) tested blood samples from centre 2 showed reactivity on either or both ELISAs. All 83 reactive samples were sent for confirmation to the Diagnostic Centre of the Swiss Tropical and Public Health Institute (Swiss TPH) in Basel, Switzerland. Sixteen samples, which previously were reactive in the routine Plasmodium spp. EIA assays, were proven positive after confirmation testing (i.e., 4 positive and 12 inconclusive results), indicating an anti-Plasmodium antibody prevalence in blood donations of 1.5%. From these 16 reactive samples, 13 were also detected by the index test, resulting in an assay sensitivity of 81.2%. A specificity of 98.6% was calculated (1,065/1,080 confirmed negative samples). The overall agreement with the reference centre was 95.8% in centre 1 and 94% in centre 2. Conclusion: The comparison of the new EUROIMMUN ELISA and the established CAPTIA™ Malaria EIA (Trinity Biotech) and Malaria EIA (BioRad) used for routine blood donor screening in two laboratory blood donation centres revealed that all tested ELISAs show comparable sensitivities and are equally suitable for anti-Plasmodium antibody screening in blood banks.

The transfusion of blood and its component is very essential health care modality wherein it saves life, but can also be hazardous to recipients. Despite of stringent screening methods done prior to transfusion there is always a bleak possibility of getting infections like HIV, HCV, HBV, Treponema pallidum and malaria. This study was a retrospective study carried out at Blood Bank and Component Lab, Dr. Panjabrao Deshmukh Memorial Medical College, Amravati over period of five years. A total of 52606 donor’s blood was collected over the period of 5 years (From 1st January 2012 to 31st December 2016). Out of these 45,796 (87.05%) were voluntary blood donations and 6,810 (12.94%) were replacement Blood donations. The overall seropositivity for all TTIs (HIV, HCV, HBV, Treponema pallidum and malaria) over a period of five years was found to be 1425 (2.71%) in which 1081 (2.36%) were voluntary donors and 344 (5.05%) were replacement donors. It was observed from the findings of this study that seropositivity rate of TTIs was less among voluntary donors. It was concluded that to improve blood safety extensive donor selection, use of sensitive screening and establishing strict guidelines in blood transfusion will help us to reduce burden of TTIs in our society.

espanolObjetivo. Como pais caribeno, la Republica Dominicana es considerada endemica para HTLV-1. El proposito de este trabajo es analizar la seroprevalencia y la tendencia del HTLV-1/2 en donantes de Santo Domingo, que al ser la capital concentra la mayoria de las donaciones. Tambien pretendemos comparar nuestros hallazgos con los datos de los paises vecinos. Pacientes y metodos. Hemos realizado un estudio transversal retrospectivo de los 10 centros de transfusion de Santo Domingo que comunicaron la deteccion de HTLV y las otras infecciones de transmision sanguinea en su totalidad, que representan mas del 40% de las donaciones de la provincia. Se determino la seroprevalencia anual de HTLV-1/2, la prevalencia del periodo (2012-2017) y la tendencia temporal. Resultados. Se evaluaron un total de 352.960 donaciones. La prevalencia de HTLV-1/2 en el periodo estudiado fue del 0,26% (929/352.960) (IC del 95%: 0,24–0,28%). Encontramos un marcado predominio de la donacion de reemplazo en comparacion con la voluntaria. Por lo tanto, este estudio puede proporcionar claves sobre la prevalencia general de la infeccion. Conclusiones. La seroprevalencia de HTLV-1/2 en donantes de sangre de Santo Domingo, Republica Dominicana, ha sido relativamente baja y estable en el periodo estudiado. EnglishObjectives. Being a Caribbean country, the Dominican Republic is considered endemic for HTLV-1. Viral screening in blood banks is recommended for this blood borne infection. The purpose of this work is to analyze the seroprevalence and trends of HTLV-1/2 in the Dominican Republic blood donors; it is focused on Santo Domingo, the capital of the country, which has the largest blood donation activity. We also aim at comparing our findings with published data from neighboring countries. Patients and methods. We performed a retrospective cross-sectional study of 10 blood centers of Santo Domingo, which reported HTLV and the other blood-transmitted infections in full. They represent more than 40% of the province’s blood donations. Annual seroprevalence of HTLV-1/2, period prevalence (2012-2017), and time trend were determined. Results. A total of 352,960 blood donations were evaluated. The HTLV-1/2 period prevalence was 0.26% (929/352,960) (95% CI: 0.24–0.28%). We also found a marked predominance of replacement donation (90.4%) in comparison to voluntary contributions (9.6%). Therefore, this blood donor study may provide clues on the general prevalence of the infection. Conclusions. Seroprevalence of HTLV-1/2 in blood donors of Santo Domingo, Dominican Republic, showed a relatively low and steady trend in the studied period.

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), was first identified in Wuhan, China, in December 2019, with subsequent worldwide spread. The first US cases were identified in January 2020. Methods To determine if SARS-CoV-2–reactive antibodies were present in sera prior to the first identified case in the United States on 19 January 2020, residual archived samples from 7389 routine blood donations collected by the American Red Cross from 13 December 2019 to 17 January 2020 from donors resident in 9 states (California, Connecticut, Iowa, Massachusetts, Michigan, Oregon, Rhode Island, Washington, and Wisconsin) were tested at the Centers for Disease Control and Prevention for anti–SARS-CoV-2 antibodies. Specimens reactive by pan-immunoglobulin (pan-Ig) enzyme-linked immunosorbent assay (ELISA) against the full spike protein were tested by IgG and IgM ELISAs, microneutralization test, Ortho total Ig S1 ELISA, and receptor-binding domain/ACE2 blocking activity assay. Results Of the 7389 samples, 106 were reactive by pan-Ig. Of these 106 specimens, 90 were available for further testing. Eighty-four of 90 had neutralizing activity, 1 had S1 binding activity, and 1 had receptor-binding domain/ACE2 blocking activity >50%, suggesting the presence of anti–SARS-CoV-2–reactive antibodies. Donations with reactivity occurred in all 9 states. Conclusions These findings suggest that SARS-CoV-2 may have been introduced into the United States prior to 19 January 2020.

PurposeAlthough blood banks have recently started to recruit blood donors through social media platforms, including WeChat, to increase recruitment effectiveness, few researchers have studied their effects on blood donation behavior. The aim of this study is to examine the influence of using official WeChat accounts on repeat blood donation behavior.Design/methodology/approachThis paper used the backstage operation data of official WeChat accounts and blood supply chain management system data from the blood bank for the study to analyze the changes in repeat blood donation behavior. First, to analyze the changes in the average frequency of blood donation per year, average volume of single blood donation and blood eligible rate of repeat blood donors before and after following the official WeChat accounts by difference-in-differences model combined with propensity score matching (PSM-DID). Second, we examined the impact of official WeChat accounts on the proportion of repeat blood donors through survival analysis.FindingsThe results show that following WeChat accounts increases the average frequency of blood donation and blood eligible rate of repeat blood donors by 14.36% and 1.19%, respectively, and have no significant effect on the average volume of single blood donation. Further, WeChat accounts have a more significant impact on the average frequency of blood donations per year for workers, farmers, medical staff and groups with education levels of junior high school. In addition, official WeChat accounts can effectively increase the proportion of repeat donors.Originality/valueThe results provide a quantitative basis for the influence of official WeChat accounts on repeat blood donation behaviors. On the one hand, it is of great significance to guide the publicity and recruitment of unpaid blood banks. On the other hand, it provides an evidence for the promotion of official WeChat accounts.

Background COVID-19 first appeared in Iran on 19 February 2020, and then spread rapidly over the country. In this article, we review the action plan of the Iranian Blood Transfusion Organization with respect to this disease. Method and materials We collected data on blood donations and RBC inventory for the first 8 weeks of the outbreak. We also evaluated the trend of blood donations and RBC inventory and compared them with the data of the past year. We include a summary of actions taken by the National Committee on Management of COVID-19 outbreak. Results Blood donations decreased from 33 275 to 23 465 units during the first 2 weeks of the outbreak with a corresponding decrease in the RBC inventory. But after that, donations gradually increased from 23 465 to 29 665 units. RBC inventory levels improved at the same time. Then, the Iranian New Year's holiday resulted in another downward trend. After the holiday, blood donations revived, along with the RBC inventory. Discussion Although it appears that this virus cannot be transmitted through transfusion, changes in lifestyle had a significant impact on reducing blood supply. Following implemented measures, we saw an upward trend in blood donations and an adequate supply of RBC units in blood centres, helped by a reduction in demand by hospitals. Blood centres need to be more prepared to manage future viral disasters, especially in case of transfusion-transmissible infections.

Background: The ongoing demographic changes in Poland affect the number of donors and donations with direct impact on provision of blood and blood components for transfusion. With predicted population-decline, the number of potential donors is likely to decrease while the demand for blood is bound to increase as more people will require blood therapy. The structure of the Polish donor population reporting for blood donation is not uniform, moreover it has undergone additional changes within the study period. So it seems justified to perform in-depth analysis of the dynamics of changes in the number and structure of donor group as well as determine the direction and intensity of these changes in spatial and temporal terms. Identification of the possible causes of change is also important. Aim: presentation of the structure characteristics of the donor group who reported at the Polish regional blood transfusion centers (RBTCs) in the period 2005–2017 with the intention of donating blood/ blood components. Materials and methods: Analyses of available data-sets — annual reports from 21 Polish RBTCs forwarded to the IHTM. The following tools were used for statistical analysis: Microsoft Office: Access and Excel, Microsoft Power Business Intelligence (Power BI) software and STATISTICA version 13.3 software (TIBCO Software Inc.). Results: In 2005–2017 the total number of donors amounted to 8 691 611 including 2 542 621 (29.3%) women and 6 148 990 (70.7%) men. Voluntary non-remunerated donors were estimated at 8 684 069 (99.9%). The average annual number of donors per RBTC was 31 837 and included 31 809 voluntary non-remunerated donors; 22 524 men and 9314 women. Countrywide, the highest number was reported for the period 2011–2013; 701 882 (8.08%), 707 578 (8.14%) and 706 246 (8.13%) for respective years and for the period 2015–2016 the numbers were 718 887 (8.27%) and 706 476 (8.13%) respectively. The highest number for the period was reported by 5 RBTCs: Warsaw (951 068 — 10.94%), Katowice (748 841; 8.62%), Poznan (702 087; 8.08%), Krakow (651 057; 7.49%) and Wroclaw (556 357; 6.40%). In the number of 2 352 099 donors who have recently reported for blood donation at the RBTCs the 25–44 age group was the largest (48%). The least numerous was the 45–65 age group — 548 885 (ca. 11%). There were 2 030 692 donors in the 18–24 age category ( > 41% of the total donor-population).Trend-analysis demonstrated an upward tendency for the category of 25–44 age donors and a downward one for the 18–24 age category. No explicit trend was observed for the 45–65 age group. Conclusion: The number of blood donations in Poland has recently reached the limit of approximately 1 200 000 donations per year. To exceed this limit will be no easy task. All efforts must therefore be focused on promoting people’s willingness to donate blood. The analysis indicates a falling tendency for the 18–24 age group and a rising one for higher age groups, which only raises concern for the future. The priority is therefore to motivate people of all agegroups to donate blood and become multiple donors with special emphasis however on the very young people as they are the potential source for many years to come. Promotion of voluntary non-remunerated blood-donation among children is equally important; in several years’ time transfusion medicine will depend on their willingness to donate blood.

First published online: 15 May 2020 Positive feedback about the outcome of volunteers' prosocial actions is often thought to help motivate continued volunteers' engagement. In the context of blood donations, various collection systems have begun to provide blood donors feedback on successful utilization of their blood donation. An experiment conducted by the main NGO that supports the collection of blood in Italy studies how such feedback affects subsequent blood donations. From a sample of over 8'000 blood donors, we find that providing feedback of successful utilization decreases donations. Though surprising, these results are consistent with theoretical models in which individuals engage in prosocial behavior to sustain a positive self-image : feedback about the outcome of a recent donation can act as reminders that boost self-image and reduce the need for re-engaging soon in prosocial activities. Interestingly for policy, we also show that combining the feedback with an explicit request to sign up for a new donation can eliminate, but not overturn, the negative effect of the feedback.

Blood is one of the most important parts in the human body because blood has a function to circulate the juice, carry oxygen, circulate hormones, and others. If humans reduce blood caused by accidents or anemia, so that humans lack blood or store dirty blood in the body, then it can cause diseases that endanger the health of even someone. Blood donor activity is an activity of the process of blood transfer from donors to people who lack blood. The process is carried out by those who carry out blood processing processes such as the Blood Transfusion Unit (UTD) under the auspices of the Indonesian Red Cross (PMI). UTD PMI Pekanbaru City only has a web-based blood donor information system, so UTD PMI Pekanbaru City wants to keep up with the times where many users use smartphones so they want to upgrade from the web version to the Android version. The reason for the improvement of this system aims to reduce hosting costs to be paid when using a web system and Android-based information system does not require typing too much when the user will carry out an order to the system, its use is not limited by space and place, and does not really need a connection that is prime to run the system. Android-Based Donor Information System in the Indonesian Red Cross Blood Transfusion Unit (UTD PMI) Pekanbaru City can help all people to find out about information about blood donations well by using Android-based smartphones as interesting media.

Blood donor activities are specifically the responsibility of the Indonesian Red Cross Blood Transfusion Unit Pekanbaru City. In addition, there is also the authority of the hospital to form a Blood Bank and for certain cases special handling becomes the authority of the central government. Given the importance of blood for humanitarian missions, it is necessary to have the active involvement of all elements of society to donate blood regularly. From the observations made, it was found that problems were still found by people who were confused in administrative matters. Then there are still many Pekanbaru City residents who have never done blood donor activities, not all agencies that require employees to do blood donations. Therefore it is necessary to do qualitative research to overcome these problems using the Lijan Sipoltak theory. The informants used were blood donor and community apparatus units. As a result, the quality of public services has run according to applicable regulations but still needs improvement.

Background and objectives Assessment of HBV-NAT testing compared to HBsAg and anti-HBc screening in German blood establishments for the period 2008-2015. Materials and methods Blood donations screened for HBsAg and anti-HBc along with HBV-NAT were evaluated. Sensitivity of HBsAg and HBV-NAT tests was compared in 30 HBV seroconversion panels and with the viral load of the NAT-only cases. Residual risk for HBV in the WP was modelled. Results A total of 45 270 111 donations were evaluated. There were 29 NAT-only cases in the HBsAg-negative HBV-WP, one by ID-NAT and 28 by MP-NAT. MP-NAT, on average, showed higher sensitivity than HBsAg testing: MP-NAT-LoD of 146 IU/ml vs. 362 IU/ml HBV DNA for positive HBsAg detection (range 135-1502 IU/ml), resulting in 3·1 days (range 2·0-4·8 days) earlier HBV detection. Viral loads of the NAT-only cases confirmed the sensitivity of the HBV tests in the seroconversion study. One HBsAg-negative case was due to a new HBsAg mutant combination. There was one HBsAg-reactive only case. In addition, HBV incidence in the HBV-WP included 41 HBsAg-/HBV-NAT-positives and three HBV transmission cases. The residual risk for HBsAg was estimated to be 1:1 619 419-1 268 474 compared to 1:2 793 365-2 134 702 for MP-NAT. Within chronic HBV (HBsAg-/anti-HBc-positive and MP-NAT-negative) 70% were ID-NAT positive at low viral load (median 20 IU/ml). Among anti-HBc-only, supplementary ID-NAT detected 23 occult HBV infections. Conclusions In the HBV-WP, MP-NAT provided a higher sensitivity than HBsAg testing, obtained a considerably higher yield and reduced the risk for HBV transmission. In later HBV stages, anti-HBc screening and HBV-ID-NAT intercepted potentially infectious donations.

Objective: The aim of this study was to describe the characteristics of blood donors and the serological profile of the blood donations at the blood bank of the University Hospital Polydoro Ernani de São Thiago of the Federal University of Santa Catarina from January 2011 to December 2016. Methods: The characteristics of donors and the serological results of the donated blood were compiled from databases. Only donations with a negative serology or a positive serology confirmed by second-sample testing were included in the study. Results: A total of 14,368 donations were included in the study, of which 118 (0.8%) had a confirmed positive serology. Of the total donations, 94.3% were from spontaneous donations and 5.7% from replacement donation. Donations were predominantly from men (54.1%), individuals aged 18 to 29 years (69.1%), and repeat donors (47.7%). Detection rates were higher for HBV (0.63%), followed by syphilis (0.13%), HIV (0.05%), HCV (0.02%), and Chagas disease (0.01%). With the exception of HIV, positive results were more frequent in the older age groups. Positive results for HBV, HCV, and HIV were more frequent among first-time donors. Replacement donations were more likely to have HBV (OR 7.7; 95% CI 4.9–12.1, p

Introduction: In Burkina Faso, screening for hepatitis C virus in blood donations is made using sensitive ELISA (Enzyme Linked Immuno Sorbent Assay) type kits. However, no confirmation of the positive results obtained with these kits is made before their notification to the blood donors due to the high costs of the confirmation kits of immunoblots type. Objective: Evaluate two rapid kits against one immunoblot kit in order to determine the most efficiency which will be proposed as an alternative for the confirmation of ELISA tests in the socio-economic context of Burkina Faso. Material and Methods: The study was carried out using a panel of 72 sera, of which 22 were positive for anti-HCV antibodies and 50 were negative. The sera were tested using the Monolisa® HCV Ag-Ab ULTRA kit and confirmed with the DECISCAN HCV Plus kit. The panel was then tested with the SD BIOLINE HCV kit and the HCV TRI-DOT kit and the results obtained were evaluated against those of the DECISCAN HCV Plus kit used as “gold standard”. Results: Compared to the DECISCAN HCV Plus kit, the HCV TRI-DOT kit exhibited a sensitivity and specificity of 100% and the SD BIOLINE HCV kit a sensitivity of 86.36% and a specificity of 100%. Conclusion: Based on the results recorded by the HCV TRI-DOT kit, it would be best suited to the sero-epidemiological context of blood donors from the National Blood Transfusion Center and could be proposed as an alternative for confirmation of ELISA tests.

Does social recognition motivate prosocial individuals? We run large-scale experiments among members of Italy’s main blood donors association, testing social recognition both through social media and peer groups. We experimentally disentangle visibility concerns and peer comparisons, and we study how exposure to different norms of behavior affects giving. In an initial study and two subsequent replications, we find that a simple ask to donate is at least as effective as asks that offer social recognition. A survey experiment with blood donors provides consistent evidence that social recognition backfires when offered to good citizens, as signaling focuses on image motivation. Our results caution against over-reliance on social recognition to promote good citizenship and emphasize the importance of surveying beliefs in the target population to anticipate the outcomes of a policy at scale.

Background The rate of viral infections in donated bloods is one of the main indicators of blood safety which has to be monitored precisely. This paper provides a thorough study of blood safety indicators in the last 15 years in Iran. Methods The data of the transfusion organization in Iran from years 2003 to 2017 were used. The study focuses on the analysis of the frequency of viral hepatitis B and C (HBV and HCV) as well as human immunodeficiency virus (HIV) in blood donations. Results Of 27,442,124 donated bloods, the relative frequencies were 4, 302, and 81 for HIV, HBV and HCV, respectively. This study also shows that the corresponding frequencies were significantly lower in recent years (2.5, 53, and 26 per 100,000 samples in 2017). Conclusion The presented study indicates an overall low infection rate and provides evidence for the effectiveness of modern safety measures in improving the level of blood safety in Iran.

Background Physicians may be an important source of blood donations as they are more likely to be familiar with the importance of donating and the donation process. The aim of this study is to report physicians' knowledge, attitudes, and practices towards voluntary and non‐voluntary blood donations. Study Design and Methods This was a cross‐sectional study conducted at King Faisal Specialist Hospital and Research Centre (KFSH&RC), Saudi Arabia. One‐hundred‐and‐sixteen physicians and dentists responded to an online structured questionnaire sent to their institutional emails. Results Sixty‐eight percent of participants (79% of males and 43% of females) reported previously having donated blood. Eighty‐six percent of donors had previously donated on a voluntary basis, whereas 31% of donors had previously donated for a specific person. A recent donation within 5 years was associated with the younger age group and knowledge of the minimum interval between donations. Fifty‐six percent of participants agreed with using replacement donations. Compared to participants in the youngest age group (25‐35 years), older participants in the age groups (46‐55 years) and (>55 years) were less likely to express intention to donate in the next 6 months (OR 0.289, P = .022 and OR 0.083, P = .004, respectively). Participants reporting poor nutritional status or other medical reasons as a barrier to donating blood were less likely to intend to donate (OR 0.146, P

Objective This work aimed to establish the effects of the COVID‐19 pandemic on blood collection and blood product usage at the end of the first year. Background The arrival of SARS‐CoV‐2 to Colombia on March 6, 2020, triggered closure of borders and mandatory lockdown from March 23, 2020. Methods/Materials The Colombian National Institute of Health administers the National database of confirmed cases of SARS‐CoV‐2 and the National Haemovigilance System. We examined positive SARS‐CoV‐2 cases identified between March 6, 2020, and March 6, 2021, using positive RT‐PCR testing (72.8%) or reactive antigen (27.2%). We also analysed accepted and deferred donors' information provided by 100% of blood banks and transfused patients notified by 83% of health care facilities nationwide, between March 1, 2019, to February 28, 2021. Results Colombia registered 2 273 245 SARS‐CoV‐2 cases. From these, 60 412 people died from COVID‐19 (2.7%) and 2 172 418 individuals recovered (95.6%). There were 11 659 216 SARS‐CoV‐2 processed samples nationwide. People between the ages of 20 and 39 years concentrated 44.4% of the SARS‐CoV‐2 cases. There were 773 569 blood donations, mainly from a 20‐39‐year‐old population (60.5%). The pandemic caused a reduction of 155 393 blood donations (16.7%) and 51 823 total deferrals (33.7%). An 18.4% drop in volunteer donors and a 37.3% increase in donations from family/replacements members were observed. There were 399 453 transfused patients and 1 179 895 blood components administered (−8.7% and − 13.9% compared to March 2019–February 2020). Conclusion Mandatory lockdowns in Colombia decreased blood collection and usage, resulting in a reduction of blood components transfused to individual patients.

Blood collection has been a crucial procedure for different hospitals and blood banks to obtain blood supply in order to be used in various therapeutic procedures for the patients. Conducting blood collection drives offer access to quality and safe health services given to the patients that need blood. The current situation of the healthcare system is being hindered by the COVID-19 pandemic which made a lot of restriction and limitation to hospitals due to quarantine protocols and social distancing. Blood donation is one of the affected procedures by the COVID-19 and it is the purpose of this study to determine the rates of blood donation in selected hospital-based blood banks of Quezon City during the pandemic crisis. The trends of blood donation between phase 1, phase 2, and phase 3 of the pandemic from November 2019 to February 2020, March 2020 to May 2020, and June 2020 to October 2020 respectively is compared to find changes and effects of the pandemic to health services. This research is focused on the comparative analysis on the data gathered from the blood banks and is used to monitor the trends of blood donation services. The researchers had formulated a consent letter that was reviewed by the ethics committee and was sent to the blood banks for data privacy purposes. A letter requesting for the amount of blood donation per month of specified dates was given to the hospitals. The letter will be accessible online through email for easier access and gathering of data. Those hospitals which agreed to participate in the study and willing to share data will be included in this paper. The collected data was statistically analyzed by using IBM® SPSS® Statistics. Five hospitals were able to participate and give data on the number of blood donations. The analysis showed that most numbers of blood donations happened in phase 1 with 49.54% of the total donations throughout the study while the lowest is in phase 2 which only has 15.2%. The phase 3 period had 35.26% of the total donations which increased from phase 2. Based on the statistical analysis, the result from One way ANOVA proved that there were no significant differences between the 3 phases in the study. The rate of change in blood donation showed a decrease of 69.33% in phase 2 from the total donations in phase 1. On the other hand, phase 3 had a 132.05% increased rate from the total donations in phase 2. In conclusion, blood donation rates were affected based on the quarantine protocol which drastically decreased during phase 2 and increased in phase 3. Other than that, the study found out that donor attendance was also less in the pandemic phase than the pre-pandemic phase because of restrictions and health protocols in hospitals and in public.

Introduction Supplemental data from the 2019 National Blood Collection and Utilization Survey (NBCUS) are presented and include findings on donor characteristics, autologous and directed donations and transfusions, platelets (PLTs), plasma and granulocyte transfusions, pediatric transfusions, transfusion-associated adverse events, cost of blood units, hospital policies and practices, and implementation of blood safety measures, including pathogen reduction technology (PRT). Methods National estimates were produced using weighting and imputation methods for a number of donors, donations, donor deferrals, autologous and directed donations and transfusions, PLT and plasma collections and transfusions, a number of crossmatch procedures, a number of units irradiated and leukoreduced, pediatric transfusions, and transfusion-associated adverse events. Results Between 2017 and 2019, there was a slight decrease in successful donations by 1.1%. Donations by persons aged 16-18 decreased by 10.1% while donations among donors >65 years increased by 10.5%. From 2017 to 2019, the median price paid for blood components by hospitals for leukoreduced red blood cell units, leukoreduced apheresis PLT units, and for fresh frozen plasma units continued to decrease. The rate of life-threatening transfusion-related adverse reactions continued to decrease. Most whole blood/red blood cell units (97%) and PLT units (97%) were leukoreduced. Conclusion Blood donations decreased between 2017 and 2019. Donations from younger donors continued to decline while donations among older donors have steadily increased. Prices paid for blood products by hospitals decreased. Implementation of PRT among blood centers and hospitals is slowly expanding.

The low retention rate and lack of long-term blood donors are still worldwide problems, and the fostering and retaining of more blood donors has posed an urgent problem that requires a solution. The purpose of this study was to explore the role of functional motivation and blood donor stage in the future intention to donate blood. Three sites in China provided 252 blood donors who filled out a questionnaire including the volunteer function inventory, their future intention to donate blood, number of blood donations and demographic information. Based on a functional motivation approach, we investigated the motivations that influence unpaid blood donors’ future intention through qualitative interview methods. The results showed that blood donor stage moderated the relationship between values motivation and future intention to donate blood. More specifically, the predictive effect of values motivation on future intention decreased gradually from new donors to regular donors. Our study found that the effect of various motivations on blood donors’ intention was conditional, this effect changed with the development of blood donor behavioral stages. The results are significant in practice for establishing effective intervene strategies in maintaining blood donors.

Background Human babesiosis is a zoonotic infection caused by an intraerythrocytic parasite. The highest incidence of babesiosis is in the United States, although cases have been reported in other parts of the world. Due to concerns of transfusion-transmitted babesiosis, the US Food and Drug Administration (FDA) recommended year-round regional testing for Babesia by nucleic acid testing or use of an FDA-approved device for pathogen reduction. A new molecular test, cobas Babesia (Roche Molecular Systems, Inc.), was evaluated for the detection of the four species that cause human disease, Babesia microti, Babesia duncani, Babesia divergens, and Babesia venatorum. Study design and methods Analytical performance was evaluated followed by clinical studies on whole blood samples from US blood donations collected in a special tube containing a chaotropic reagent that lyses the red cells and preserves nucleic acid. Sensitivity and specificity of the test in individual samples (individual donation testing [IDT]) and in pools of six donations were determined. Results Based on analytical studies, the claimed limit of detection of cobas Babesia for B. microti is 6.1 infected red blood cells (iRBC)/mL (95% confidence interval [CI]: 5.0, 7.9); B. duncani was 50.2 iRBC/mL (95% CI: 44.2, 58.8); B. divergens was 26.1 (95% CI: 22.3, 31.8); and B. venatorum was 40.0 iRBC/mL (95% CI: 34.1, 48.7). The clinical specificity for IDT was 99.999% (95% CI: 99.996, 100) and 100% (95% CI: 99.987, 100) for pools of six donations. Conclusion cobas Babesia enables donor screening for Babesia species with high sensitivity and specificity.
