Impact of COVID-19 in the attendance of blood donors and production on a Brazilian Blood Centres.

BACKGROUND: One of the effects of the coronavirus disease 2019 (COVID-19) pandemic is the risk of shortages in Blood Centres. OBJECTIVES: To verify the impact of the COVID-19 pandemic on the blood donor's attendance and production of blood components in Fundação Hemominas, a Brazilian public institution was formed by several Blood Centres. METHODS: A cross-sectional study was carried out from January to June 2020. Data collected were compared to a historical series from 2016 to 2019. RESULTS: The study showed a reduction in the attendance of blood donors, whole blood collections and blood component production from March 2020, when the first case of COVID-19 was notified in Minas Gerais, Brazil. The results evidenced that Hemominas Blood Centres were affected in a very distinct way by the pandemic with a general mean reduction around 17% in attendance of blood donors and in production of blood components in the period of March to June. On the other hand, the return of blood donors rate increased. CONCLUSION: The reduction in blood donation during the pandemic period was significant, despite the measures adopted. Still, the recruitment of return donors appears to be an important measure to be considered to decrease the pandemic's effect on blood stocks.

Social distancing measures and demands for the reorganization of hemotherapy services in the context of Covid-19. / Medidas de distanciamento social e demandas para reorganização dos serviços hemoterápicos no contexto da Covid-19.

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

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

Dangerous shortage of blood banks as an indirect effect of SARS-CoV-2: An obstetrics perspective.

OBJECTIVE: To describe the impact of the SARS-CoV-2 pandemic on the frequency of blood donation (BD) in a Latin American hospital and how the social isolation policy implemented during the pandemic jeopardizes the quality of postpartum hemorrhage (PPH) care due to shortages at blood banks (BB). METHODS: A retrospective, descriptive study was conducted, lasting for 31 months, including the start of the pandemic. Frequency of BD and the use of obstetric emergency services was observed. RESULTS: A direct relationship was observed between the pandemic and a decrease in BD. Although emergency obstetric visits decreased, the frequency of deliveries and cases of PPH remained unchanged. After applying strategies to promote voluntary BD, a very slight increase was observed in the frequency of BD, with a negative indicator persisting between donation and blood demand. CONCLUSION: The SARS-CoV-2 pandemic has led to shortages at BBs. In this context, typical measures to encourage an altruistic attitude toward BD have not had a significant impact. As causes of PPH continue, quality of care may be affected by the current situation at BBs. Governments and institutions must implement new strategies to motivate BD.

Screening the Blood Supply for Zika Virus in the 50 U.S. States and Puerto Rico: A Cost-Effectiveness Analysis.

Background: In 2016, universal individual donation nucleic acid testing (ID-NAT) of donated blood for Zika virus began in U.S. states and territories. Objective: To assess the cost-effectiveness of universal ID-NAT in the first year of screening compared with alternatives for the 50 states and separately for Puerto Rico. Design: Microsimulation that captured Zika-related harms to transfusion recipients, sexual partners, and their infants. Data Sources: National testing results compiled by AABB and costs, utilities, and outcome probabilities estimated from the literature. Target Population: Transfusion recipients. Time Horizon: Lifetime. Perspective: Societal. Intervention: Universal ID-NAT, universal mini-pool NAT (MP-NAT), and ID-NAT exclusively for components transfused to women of childbearing age. Seasonally targeted strategies in Puerto Rico and geographically targeted strategies in the 50 states were also considered. Outcome Measures: Costs, quality-adjusted life-years (QALYs), and outcomes. Results of Base-Case Analysis: In Puerto Rico, MP-NAT exclusively during high mosquito season was cost-effective at $81 123 per QALY (95% CI, -$49 138 to $978 242 per QALY). No screening policy was cost-effective in the 50 states. Universal ID-NAT cost $341 million per QALY (CI, $125 million to $2.90 billion per QALY) compared with no screening in the 50 states. Results of Sensitivity Analysis: In Puerto Rico, MP-NAT only during the season of high mosquito activity was most cost-effective in 64% of probabilistic sensitivity analysis iterations. In the 50 states, no intervention was cost-effective in 99.99% of iterations. Cost-effectiveness was highly dependent on the rate of assumed infectious donations. Limitation: Data were limited on the component-specific transmissibility of Zika and long-term sequelae of infection. Conclusion: Screening was cost-effective only in the high mosquito season in Puerto Rico, and no evaluated screening policy was cost-effective in the 50 states. During periods with lower rates of Zika-infectious donations, the cost-effectiveness of screening will be even less favorable. Primary Funding Source: None.

High-throughput strategy for molecular identification of Vel- blood donors employing nucleic acids extracted from plasma pools used for viral nucleic acid test screening.

BACKGROUND: Serologic methods to determine the Vel- phenotype require the use of rare human antisera and do not allow for many samples to be tested simultaneously, which limits their application as a tool to search for rare donors. This study developed a low-cost molecular screening strategy using real-time polymerase chain reaction (PCR) and DNA, extracted from plasma pools for viral nucleic acid test (NAT) screening, to identify Vel- and Vel+(W) donors. STUDY DESIGN AND METHODS: A total of 4680 blood donors from the Brazilian southeast region were genotyped through real-time PCR targeting the 17-nucleotide (c.64_80del) deletion in the SMIM1 gene, which determines the Vel- phenotype, by using remaining nucleic acid from plasma pools of six donors, routinely discarded after the release of viral NAT results. RESULTS: Twenty pools tested reactive and individual testing of samples from reactive pools identified 19 heterozygous donors with the SMIM1*64_80del deletion (0.40%) and one homozygous donor (0.02%). Fourteen of the 19 donors were confirmed as Vel- or Vel+(W) using anti-Vel human antiserum. CONCLUSION: The DNA pool genotyping strategy using real-time PCR designed to detect the deletion in the SMIM1 gene proved effective and accurate in identifying donors with the Vel- and Vel+(W) phenotypes. The fact that remaining nucleic acid from routine viral NAT screening was used makes this technique economically attractive and definitely superior to the serologic techniques available to search for this rare phenotype.

Razones por las que las personas donan o no donan sangre en Guatemala / Reasons why people donate or do not donate blood in Guatemala

Estudio descriptivo realizado para determinar la percepción que tienen los guatemaltecos y guatemaltecas sobre la donación voluntaria de sangre. Se utilizaron tres encuestas dirigidas a tres poblaciones diferentes: personas que si donan, personas que no donan (observadoras) y personas que fueron diferidas durante la donación . De las 518 personas que acudieron a las diferentes colectas de donación voluntaria, únicamente 378 (73%) participaron en las encuestas. Se logró establecer que las personas que donan se sienten motivadas a colaborar con los que necesitan los hemoderivados. Los que fueron diferidos se mostraron decepcionados por no haber logrado pasar el proceso previo a la donación. Los observadores sentían curiosidad por el proceso pero no mostraron disposición para donar, o para aceptar la responsabilidad de que su sangre fuera transfundida...(AU)

It is a descriptive study to determine the perception Guatemalans on voluntary blood donation. If people donate , people do not donate ( observer ) and people that were deferred during the donation , three surveys of three different populations were used. Of the 518 people who attended the various collections of voluntary donation, only 378 ( 73 %) participated in the polls. It was established that people who donate are motivated to collaborate with those who need blood products. Those who were deferred were disappointed not to have made it through the pre- donation process. The observers were curious about the process but did not show willingness to donate , or to accept responsibility for his blood was transfused...(AU)

Genomic Assays for Identification of Chikungunya Virus in Blood Donors, Puerto Rico, 2014.

A newly developed transcription-mediated amplification assay was used to detect chikungunya virus infection in 3 of 557 asymptomatic donors (0.54%) from Puerto Rico during the 2014-2015 Caribbean epidemic. Viral detection was confirmed by using PCR, microarray, and next-generation sequencing. Molecular clock analysis dated the emergence of the Puerto Rico strains to early 2013.

[The cord blood bank at the Instituto Mexicano del Seguro Social]. / El banco de cordón umbilical del Instituto Mexicano del Seguro Social.

BACKGROUND: Hematopoietic stem cells have been used for over 50 years in the treatment of diverse diseases. Umbilical cord blood (UCB) has proved to be a viable source of hematopoietic stem cells for transplantation purposes. The aim was to report the contribution of the umbilical cord blood bank over the past 9 years, in the treatment of various diseases. METHODS: Since 2005 the number of units of blood from the umbilical cord and their use for transplantation in diverse disease were analyzed. A selection of volunteer pregnant women in labor was performed. Umbilical cord blood was obtained from them, which underwent processing, cryopreservation and validation, as well as compatibility test before using for transplantation. RESULTS: Ten thousand and ninety nine candidates to donation were assessed, from whom 2481 unit of UCB were collected. Of these, 893 unit were processed and cryopreserved for transplantation. In 65% of cases there was histocompatibility between the cord cell and the receptors. Transplantation was done in 87 patients, 67% had hematologic neoplasias, who have received 140 units of UCB in 102 transplants. This Bank of UCB ranks second in the world in productivity according to the rate of utility of units in transplantation (3.3%). CONCLUSIONS: Our bank of UCB has been able to develop a cell line (hematopoietic stem cells) with international quality standards and has been beneficial for patients served by our institution with need of a transplant mainly in hemato-oncologic patients.

Prevalence of antibodies against transfusion-transmissible infections (TTI) in blood donors from the Colombian eastern region.

BACKGROUND: The main purpose of this study was to establish the prevalence of antibodies against five transfusion-transmissible infections (TTIs) in blood donors from one of the most important blood banks in Colombia. METHODS: A cross-sectional, descriptive and case control study was performed from a database of Higuera-Escalante blood bank, for a period of a year. Serum was used for donor screening. Surface antigens for hepatitis B (HbsAg), anti-hepatitis C antibodies, Chagas disease, syphilis, and HIV were identified. Chemiluminescent Microparticle Immunoassay (CMIA, Abbott Diagnostics) was performed. RESULTS: From 41,575 total donors analyzed, 1,226 were reactive for any of the infectious markers (total prevalence of 2.95%). The prevalence of specific infections was: Chagas disease 0.49%, HbsAg 0.21%, HCV 0.45%, HIV 0.12%, and syphilis 1.68%. Reactivity was more frequent in men (n = 785, 64%) with a mean age of 36.35 years. HIV was present in the youngest donors with a mean age of 26.5 years (IC 95%: 23.6 - 27.6); on the other hand, Chagas disease was found in the oldest donor population, with a mean age of 40 years (IC 95%: 39.1 - 41.3). CONCLUSIONS: Identifying the prevalence of circulating antibodies against transfusion transmissible infections allows us to establish an epidemiological profile of donors inhabiting the geographic catchment area of our blood bank. Total prevalence in this study was 2.95% for any of the five markers. Syphilis prevalence demonstrates its high distribution within the blood donor population of our country, although this result could be influenced by the high rate of false-reactive test. Chagas disease is endemic in Santander, Colombia, which correlates with the results obtained in this study.

Potencial de donantes de sangre en un consultorio / Potential blood donors in a community doctor´s office

Las donaciones de sangre constituyen un acto altruista para lo cual se requiere individuos con voluntad y disposición a ello. El objetivo fue caracterizar el potencial de donantes de sangre en un consultorio. La investigación que se expone se realizó en el consultorio 16 del Policlínico Universitario Hermanos Cruz, en el período comprendido entre el 1ro de noviembre y el 31 de diciembre de 2012. Es una investigación descriptiva, observacional, de corte transversal. El universo lo constituyeron los 568 pacientes de 18 a 65 años pertenecientes al consultorio 16 y la muestra fue de 533 individuos que cumplieron los criterios de inclusión. Se respetó la ética médica. Predominó el sexo femenino y los no aptos para donar en la muestra analizada. El grupo de donantes y dispuestos a donar superó al 5 por ciento necesario para garantizar las donaciones de sangre. Predominó el sexo masculino entre los donantes, dispuestos y no dispuestos a donar y el sexo femenino entre los no aptos. La mayor parte de los no aptos toman medicamentos contraindicados para donar. La mayoría de los no dispuestos le tiene miedo al pinchazo. Una adecuada estrategia de intervención educativa permitiría eliminar algunos de estos temores y lograr que las personas los venzan. Para ello, se debe concientizar sobre la importancia de las donaciones y su utilidad. Se debe estimular moralmente a los nuevos donantes para que conozcan cuán útil ha sido su acto altruista(AU)

Blood donations are an altruistic act requiring individuals with willingness and readiness. The objective was to characterize the potential blood donors in a community doctor´s office. The research was made in the doctor´s office number 16 of Hermanos Cruz Neighborhood, in the period between November 1 and December 31, 2012. It is a descriptive, observational, cross-sectional research. The universe was composed of 568 patients from 18 to 65 years old belonging to the office 16 and the sample was 533 individuals who met the inclusion criteria. Medical ethics was respected. Predominance of female and unfit people to donate in the sample analyzed. The group of donors willing to donate exceeded the 5 per cent required to secure blood donations. Males predominated among donors, willing and unwilling to donate, and females predominated among the unfit. Most of the unfit take medications contraindicated to donate. Most unwilling people were afraid of the puncture. adequate educational intervention strategy would eliminate some of these fears and will help people overcome them. To do this, it should be raised awareness about the importance of donations and its usefulness. New donors should morally be encouraged to know how useful the donation act is(AU)

Criterios para la selección de donantes de sangre / Criteria for the selection of blood donors

Esta publicación apunta a hacer una revisión de los criterios de selección de los donantes de sangre, basadas en evidencia clínica y científica que se tradujeron en guías orientadas, fundamentalmente orientadas a resaltar aquellas situaciones en que una persona pueda donar sangre sin riesgos para el o el paciente que reciba su sangre. Esta guía pretende la revisión de los criterios de exclusión, con vistas a unificar criterios entre los distintos bancos de sangre y facilitar en la medida de lo posible, la reducción de diferimiento, fundamentalmente los temporales y su duración, de forma que redunde en un aumento de la donación sin menoscabo de la seguridad del donante y receptor

The effects of information, social and financial incentives on voluntary undirected blood donations: evidence from a field experiment in Argentina.

In many low- and middle-income countries blood donations per capita are substantially lower than in advanced economies. In these countries blood supply is mostly collected through directed donations from relatives and friends to individuals needing transfusions or to replace blood used in emergencies. The World Health Organization considers this method of blood supply inefficient compared to undirected voluntary donations. To examine methods to motivate undirected voluntary donations, we ran a large-scale, natural field experiment in Argentina, testing the effectiveness of information, social and financial incentives. We find that only higher-valued financial incentives generated more donations, increasing with the value of the reward. These incentives did not create adverse selection in the safety or usability of the donated blood. We discuss the implications of our findings for researchers interested in understanding motivations for pro-social behavior and for health agencies and policymakers concerned with the current and growing shortages in blood supply in low- and middle-income countries.

Collaboration and research as key elements for strengthening blood donation in developing nations: the case of Grenada, West Indies.

OBJECTIVE: The purpose of the study was to identify ways to strengthen the collaboration between the Grenadian Blood Bank, the St George's University (SGU) chapter of the American Medical Students Association, and St George's University Health Clinic in order to improve the promotion of blood drives and increase the number of volunteer donors. METHODS: The study had two phases. Phase 1: an assessment of the strengths and needs of the collaborators and of the blood drives. Phase 2 consisted of three student assessments: a cross-sectional survey of second year medical students, a cross-sectional survey of students in the School of Arts and Sciences and a case-control study of factors affecting student donation on the day of blood drives. Embedded within both phases were service-learning opportunities for students. Both phases received approval from SGU's Institutional Review Board. RESULTS: Preliminary achievements included a transient increase in blood donation of twenty per cent during five months though advertising of blood drives remains inadequate. Assessments reveal that most students lack knowledge about the drives, and time (medical students) and fear of needles and infection (Arts and Science students) are potential hindrances to blood donation. CONCLUSIONS: The Blood Bank needs to increase its profile on the university campus and develop a more effective promotion of the blood drives addressing the concerns of students. St George's University needs to continue supporting student involvement in health promotion activities and identify ways to ensure the sustainability and continuity of these activities. Collaboration and research are useful and effective means to promote blood donation. College students are potentially an excellent source of collaborators and donors if provided with the promotion skills and participation is made convenient.

Achieving self-sufficiency of red blood cells based on universal voluntary blood donation in Latin America. The case of Nicaragua.

In 2007, the blood collection rate in Nicaragua was 106.6 units per 10,000 inhabitants. Voluntary donation was 39%. The health authorities decided to pursue self sufficiency of blood by eliminating replacement donation and consolidating blood processing in two centers. Replacement donation was terminated in 2009, voluntary donation reached 100% in 2010, and the blood collection rate increased to 125.9 in 2011. The rate of red blood cell transfusion improved from 96.0 to 119.1 units per 10,000 during the 4-year period. The political will of the government, pertinent technical leadership, and a country-wide approach were essential for attaining those goals.

OBJETIVO: El propósito del estudio fue identificar maneras de fortalecer la colaboración entre el Banco de la Sangre de Granada, la Universidad de San Jorge (SGU), la Asociación Médica Estudiantil Estadounidense, y la Clínica de la Salud de la Universidad de San Jorge, con el fin de mejorar las campañas de donación de sangre y aumentar el número de donantes voluntarios. MÉTODOS: El estudio tuvo dos fases. Fase 1: una valoración de las fortalezas y necesidades de los colaboradores y de las campañas de donación de sangre. Fase 2, consistente en tres valoraciones de estudiante: una encuesta transversal de los estudiantes de segundo año de medicina, una encuesta transversal de estudiantes en la Escuela de Artes y Ciencias, y un estudio de caso-control de los factores que afectan la donación del estudiante el día de la campaña de la donación de sangre. Insertadas entre ambas fases se encuentran las oportunidades de aprendizaje-servicio para los estudiantes. Ambas fases recibieron la aprobación de la Junta de Revisión Institucional de SGU. RESULTADOS: Los logros preliminares incluyeron un aumento transitorio de un veinte por ciento en donaciones de sangre por un período de cinco meses, si bien los anuncios de las campañas de donación de sangre continúan siendo inadecuados. Las evaluaciones revelan que a la mayoría de los estudiantes les falta conocimientos sobre las campañas de donación, y que el tiempo (estudiantes de medicina) y el miedo a las agujas y las infecciones (estudiantes de Artes y de Ciencia) constituyen obstáculos potenciales a la donación de sangre. CONCLUSIONES: El Banco de Sangre necesita aumentar su perfil en el campus universitario y desarrollar una promoción más eficaz de las campañas de donación de sangre sobre la base de prestar atención a las preocupaciones de los estudiantes. La Universidad de San Jorge necesita continuar apoyando la participación de los estudiantes en las actividades de promoción de la salud, así como identificar maneras de asegurar la sostenibilidad y continuidad de estas actividades. La colaboración e investigación son medios útiles y eficaces de promover la donación de sangre. Los estudiantes de la universidad son potencialmente una fuente excelente de colaboradores y donantes, si se les da la oportunidad de promover sus habilidades y participar de la manera más conveniente.
