Abstract
Introduction Blood transfusions can transmit various viruses. Among them, the most common are hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). These viruses can cause fatal and life-threatening diseases. Worldwide, many people are infected with these viruses. Blood safety has made major progress in recent years. Yet, blood-borne viruses continue to be a major concern for patients, physicians, and policymakers. The aim of this study was to assess the prevalence of HIV, HBV, and HCV in blood donors. Methods A cross-sectional study was performed to assess HIV, HBV, and HCV seropositivity in blood donors. This research was carried out at the blood bank of Sidi Bel Abbes University Hospital. This was a retrospective study based on records of blood donors. All data of 10,386 donors were analyzed from January 2015 to December 2015. Biological screening was performed by enzyme-linked immunosorbent assay (ELISA) using antibodies and/or antigens. The combined HCV and HIV antigen and antibody ELISA test was utilized. To confirm the results, the blood bank and the virology laboratory used the same technique in duplicate. Results The overall seroprevalence of blood-borne viral infections (HIV, HBV, and HCV) in blood donors was 0.8%. The prevalence of HIV was found to be 0.1%, while the prevalence of HBV and HCV was 0.4%. Coinfection was rare with only one case of HBV with HIV. There was a significant difference in seroprevalence rates among blood donors compared to the general population. Significant variations were observed between the prevalence of this study and those conducted in West, East, Central, and South African countries but not with those of neighboring North African countries. The study found no association between seropositivity in blood donors and factors like age, gender, donor status, type of donation, or site. Besides, HIV, HBV, or HCV prevalence was not influenced by ABO and Rhesus blood group. Conclusion The study showed that blood donors in Algeria have a lower prevalence of blood-borne viral infections than the general population. The seropositivity rate of viral markers was similar throughout North African countries. This rate remained low compared to other African countries. Residual risk of infection persists. There is a need to increase blood safety for recipients. This report is the first comprehensive overview of blood-borne viruses among Algerian blood donors. There is a need for further nationwide studies to get a whole picture of the situation.

Chikobvu D, Chideme C. A Markov jump process approach to modeling blood donor status: Donor retention and attrition rates at a blood service center in Zimbabwe. Health Sci Rep 2022; 5:e867. [PMID: 36248355 PMCID: PMC9547117 DOI: 10.1002/hsr2.867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 09/05/2022] [Accepted: 09/15/2022] [Indexed: 11/06/2022] Open
Abstract
Background Blood service agencies depend upon the availability of regular blood donors for sustainability. The knowledge and understanding of the stochastic behavior of donors is the first step toward sustaining the blood supply. Analyzing the changes in the donor status within the donor pool will help the blood service authorities to manage the blood donation process. Objectives The study presents a multistate Markov jump model in analyzing the changes in blood donor status during their blood donation career. Relevant covariates are used to aid in explaining the transitions. Materials and Methods The status of a blood donor i that can be in one of four states S = {1; 2; 3; 4}. A new donor (s = 1), repeat/regular donor (s = 2), occasional donor (s = 3), and lapsed donor (s = 4). A Continuous‐time Markov model was used to estimate blood donor progression during their blood donation career. Frequencies of blood donations made in a given time interval determines the state occupied. Results In the early years of blood donation career, first‐time donors have a higher likelihood of becoming regular donors. Donor attrition increases with time whilst donor retention decreases with time. The results show that when the jump process is currently in an occasional state, the probability that it moves into lapsed state when it leaves the occasional state is given as 69.06%. Similarly, donors are forecasted to spend 21.193 months (1.8 years) in the occasional state before lapsing. Repeat donors can spend 39.342 months (3.3 years) in the regular state before the transition to other states. The study established that donor‐specific demographic factors such as age and gender are critical in donor status transitions. Conclusions With the passage of time, donor status evolves, with trend inclined towards reduction in the frequency of blood donations as more donors become inactive or lapsed. The transition of donors in various states can be described by a time homogeneous Markov model.

[PMID: 36687550 PMCID: PMC9855218 DOI: 10.4103/ajts.ajts_166_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 05/13/2021] [Accepted: 08/08/2021] [Indexed: 01/25/2023] Open
Abstract
CONTEXT Frequent blood donors contribute to an important share of blood donations in many countries. In Algeria, frequent donation and its determinants, notably the place of the month of Ramadan, which plays an important role in blood donation in Muslim countries, have not been studied. METHODS This was a retrospective cohort study of n = 10145 Algerians who donated blood to the blood transfusion post (BTP) of Boufarik between January 2, 2008, and December 31, 2019. Donors were assessed at each donation for general clinical information, demographic information, and dates and times of donation. Donor return, defined as two or more donations to Boufarik BTP, and frequent donation, defined as three or more blood donations to Boufarik BTP, were the outcomes of interest and were analyzed using groups comparison and logistic and Cox regression analyses. RESULTS 2.2% of donors were frequent donors and donated 9.6% of all donated blood. The volume of donated blood during Ramadan was twice the monthly volume during the rest of the year, but donation in Ramadan was associated with lower odds of return (odds ratio [OR]: 0.54, 95% confidence interval [CI]: 0.40-0.71) and frequent donation (OR: 0.41, 95% CI: 0.24-0.73). Women were underrepresented (10.9%), but they were more likely to be frequent donors (male vs. female OR: 0.55, 95% CI: 0.31-0.96; hazard ratio: 0.64, 95% CI: 0.41-0.98). CONCLUSIONS Reducing the gender gap and promoting return could significantly improve the volume of blood donations in Algeria.

Bakhos JJ, Khalife M, Teyrouz Y, Saliba Y. Blood Donation in Lebanon: A Six-Year Retrospective Study of a Decentralized Fragmented Blood Management System. Cureus 2022; 14:e21858. [PMID: 35273839 PMCID: PMC8901104 DOI: 10.7759/cureus.21858] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/02/2022] [Indexed: 12/31/2022] Open
Abstract
Introduction In developing countries, the lack of a sufficient and safe blood supply is a significant impediment to providing health care. Lebanon is notable for its absence of a Donor Management System to ensure continuous donor recruitment and scheduling. Herein, we report the findings of Lebanon's first large retrospective population-based study to investigate blood types and donation that is critical for managing community blood supply. Methods The non-remunerated voluntary blood donors were recruited by the non-profit organization “Donner Sang Compter”. The study spanned six years, from August 2015 to May 2021, and included 36,002 people from 18 districts throughout Lebanon's nine governorates. Results The most prevalent blood type was A (42%), followed by O (37.48%), B (13.86%), and the AB group (6.84%). RhD+ groups were predominant (88.45%), with A+ being the most (37.84%) and AB- being the least prevalent (1.05%). Furthermore, blood type and donation profiling revealed a substantial geographical variation in the frequency of blood groups, despite the relatively small country’s area. As for blood donation, when gender and age were considered, young male donors dominated the pool across the country. Conclusion This study on blood type prevalence and blood donor demographics may pave the way for the development of a more coherent and integrated blood management system in Lebanon, as opposed to the fragmented and decentralized system now in existence. These findings also provide crucial clinical information for the country's future transfusion medicine policies and practices, which is vital in such a precarious part of the world.

Abstract
Introduction in order to improve the safety of blood transfusion, the retention of voluntary donors remains a major concern in the Democratic Republic of Congo. Nevertheless, retention is still difficult to assess because of the lack of local studies. The present study establishes the donors' profile and regularity, as well as regularity-associated factors, at the Provincial Blood Transfusion Centre in Bukavu. Methods this descriptive and analytical cross-sectional study included the records of 387 out of 773 blood donors during the period from 2015 to 2017. Donor retention and its associated factors were measured. The composite approach used here considered the number of blood donations, their frequency, the previous regularity of donors and the inter-donation interval. Results we bring to light an important loss of regular voluntary donors in the centre. Only 23.8% of them were still regular donors in 2017. The majority of donors registered in the centre are young males and have no income. On the contrary, factors associated with the profile of a regular donor in 2017 were: age at least 46 years old, being a woman and working in the formal sector. The composite classification highlighted that an important proportion of former regular donors, namely 72.8% (N=161/221), had not given blood in 2017. Conclusion the use of a composite classification to assess the regularity of voluntary blood donors provides more accurate information that will enable the improvement of donors' awareness and retention as well as the possible reinstatement of former donors.

Abstract
Background Understanding the demographic features of blood donors is important for identifying the donor structure and guiding the recruitment and retention strategies of donors. This study was aimed to determine the demographic characteristics of blood donors, the types of donation drives, and the frequency and reasons for pre-donation deferral in our population. Methods This cross-sectional study included data analysis of all prospective blood donors presenting themselves for donation at the Blood Bank of the King Fahad Military Medical Complex, Dhahran, Saudi Arabia between January 2010 and December 2018. Eligibility of blood donation was assessed using a standardized history questionnaire, physical examination, hemoglobin estimation, pulse rate, blood pressure, and temperature. The questionnaire included the demographic features of the donor such as age, gender, and the reason for donation and other specific risk factors that potentially affect the safety of the donor or the recipient. Data analyzed using the analysis of SPSS version 20 (SPSS Inc., Chicago, IL, USA) were used to calculate the unadjusted odds ratios (OR) and the respective 95% confidence interval for the association between the various demographic parameters. Results A total of 28,189 potential donations were recorded during the study period; of these, 77.4% were family replacements with females accounting for only 1.8% of all donations. Most of the donors were Saudi nationals (92.1%) of whom donors between 18 and 34 years old constituted 87.9%, while those over 40 years old represented only 7.9% of the donations. Pre-donation temporary deferral occurred in 3300 (11.7%) of all potential donation attempts. The most common causes being the recent intake of medication (24.4%) followed by low hemoglobin (14.8%), low or high blood pressure (14.6%), low or high pulse rate (13.6%), and low weight (11.6%). Conclusion A profile of blood donors consisting mainly of young male citizens who mostly donated for family replacement was detected. Deferral rate was found to be average when compared to other countries; the causes being similar to those detected in other developed countries. Simple descriptive statistics has shown no marked difference was noted over the 9 years of the study in neither the profile of blood donors nor the cause for temporary deferral of prospective blood donors.

Abstract
OBJECTIVE Determining the current return rates of blood donors and their related factors. BACKGROUND Understanding the current pattern of blood donors' return rates and also their motivations will be beneficial when there is a need to implement measures to encourage new blood donors and retain existing ones. METHODS This cross-sectional study was conducted on 4200 blood donors in Shiraz, Iran, from 26 November 2010 to 26 December 2010. Blood donors' return rate and its related factors were investigated in a 7-year follow up. RESULTS The overall return rates of blood donors indicated a significant yearly decline of 51.2%, 45.1%, 37.6%, 38.8%, 28.7%, 22.7% and 22.1% over a 7-year follow up. The return rates for first-time donors declined annually by 30%, 25%, 21%, 18.5%, 15.2%,12.3% and 11.8% (P ≤ .05). Return rates were higher among male, older, low-educated, Rh-negative and regular donors. Blood donations for altruistic reasons and religious reasons were higher in regular and older donors (P < .001); donation for positive effects on their health and free access to screening tests and curiosity was higher in first-time donors and females (P < .001). The most frequent deterrents were lack of time (42.7%), unsuitable condition (37.6%) and difficult access to donation sites (26.2%). CONCLUSION Designing new strategies to retain donors, advertisement, appreciation methods and providing convenient conditions for donation are needed to increase the return rates, particularly in young, highly educated, female and first-time donors.

Abstract
BACKGROUND Blood transfusions are an important resource of every health-care system, with often limited supply in low-income and middle-income countries; however, the degree of unmet need for blood transfusions is often unknown. We therefore aimed to estimate the blood transfusion need and supply at national level to determine gaps in transfusion services globally. METHODS We did a modelling study involving 195 countries and territories. We used blood component preparation data from 2011-13 to estimate blood availability for 180 (92%) of 195 countries from the WHO Global Status Report on Blood Safety and Availability. We calculated disease-specific transfusion needs per prevalent case for 20 causes in the USA using the National (Nationwide) Inpatient Sample dataset between the years 2000 and 2014, and the State Inpatient Databases between 2003 and 2007 from the Healthcare Cost and Utilization Project. Using prevalence estimates for the USA from the Global Burden of Disease (GBD) 2017 study, we estimated the ideal disease specific-transfusion rate as the lowest rate from the years 2000 to 2014. We applied this rate to GBD prevalence results for 195 countries to estimate transfusion needs. Unmet need was the difference between the estimated supply and need. FINDINGS In 2017, the global blood need was 304 711 244 (95% uncertainty interval [UI] 293 064 637-314 049 479) and the global blood supply was 272 270 243 (268 002 639-276 698 494) blood product units, with a need-to-supply ratio of 1·12 (95% UI 1·07-1·16). Of the 195 countries, 119 (61%) did not have sufficient blood supply to meet their need. Across these 119 countries, the unmet need totalled 102 359 632 (95% UI 93 381 710-111 360 725) blood product units, equal to 1849 (1687-2011) units per 100 000 population globally. Every country in central, eastern, and western sub-Saharan Africa, Oceania, and south Asia had insufficient blood to meet their needs. INTERPRETATION Our data suggest that the gap between need and supply is large in many low-income and middle-income countries, and reinforce that the WHO target of 10-20 donations per 1000 population is an underestimate for many countries. A continuous expansion and optimisation of national transfusion services and implementation of evidence-based strategies for blood availability is needed globally, as is more government support, financially, structurally, and through establishment of a regulatory oversight to ensure supply, quality, and safety in low-income and middle-income countries.

Abstract
OBJECTIVES To describe the basic demographical characteristics of whole blood donors in Zhejiang Province, China, from 2006 to 2015 and to examine the trends in individual characteristics associated with blood donation and the relationship between weight and donation. DESIGN Cross-sectional study comparing characteristics of blood donors and annual donations for the period 2006 to 2015. SETTING Urban and rural communities in Zhejiang, China (11 cities, 89 districts or counties and 1379 townships). PARTICIPANTS 3 226 571 volunteer blood donors. OUTCOME MEASURES Volume of each whole blood donation and donation frequency. All data were collected by trained staff and entered into a standardised electronic information system. RESULTS The number of blood donations generally trended up in Zhejiang Province from 2006 to 2015. Donors were predominately males aged 18 to 25 years, but this major donor age group shifted to the 26 to 45 year range by 2015. The rate of repeated blood donation was 30.8 per cent. The blood volume per donation concentrated in 200 mL and 400 mL categories has been gradually shifted to 300 mL and 400 mL. Approximately one-third of donors had a college education. The average weight of donors increased over time for both men and women. Both the blood volume of each donation and donation frequency were proportional to weight. CONCLUSIONS The trend of voluntary non-remunerated blood donation in Zhejiang province is positive. However, given the expected growth in demand for whole blood, more research is needed to increase both the donor pool and the rate of repeated donation. The relationship between body weight and blood donation warrants further study because while improving nutritional status is associated with higher average donation volume and more frequent donations, overnutrition may lead to poorer quality of donated blood. Blood donation may present a unique opportunity for health education and body weight management to monitor and improve population health.

Motivational factors for blood donation in first-time donors and repeat donors: a cross-sectional study in West Pomerania. Transfus Med 2017; 27:413-420. [PMID: 28786224 DOI: 10.1111/tme.12450] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2015] [Revised: 06/29/2017] [Accepted: 07/07/2017] [Indexed: 11/28/2022]
Abstract
OBJECTIVES This study aimed to analyse motivational factors for blood donation in different donor groups. BACKGROUND As the demographic change will result in a decrease of the population in age groups of blood donors, the risk of blood product shortage increases. METHODS During a 12-month period, every sixth blood donor presenting at the blood donation centre of the University Hospital was asked to complete a self-administered questionnaire assessing motivational factors for blood donation. Despite the formalised enrolment protocol, frequent donors were over-represented in the study cohort, which was adjusted by weighting donors with different numbers of donations per year in such a way that the distribution of numbers of donations per year was the same in the sample as in the donor population. RESULTS Of 2443 participants, 14·3% were first-time and 85·3% repeat donors. To "help other people" (>90%) and receiving "medical assessment of my blood values" (63-69%) were the strongest motivational factors in all donor groups. Receiving remuneration (49·2% vs 38·1%) was more important for repeat donors than for first-time donors, whereas it was the opposite for "being taken by a friend to the donor clinic" (47·0% vs 15·5%). A potentially important observation is that 33·9% of frequent donors reported feeling physically better after blood donation compared to infrequent donors (29·5%). CONCLUSION Identification of motivational factors can lead to the design of targeted motivation campaigns for blood donation. The underlying cause of the perceived well-being after blood donation requires further studies.

Abstract
Background Blood transfusion is an essential component of a modern healthcare system. Because knowledge about blood donor demography may inform the design of strategies for donor recruitment and retention, we used nationwide registers to characterize the entire population of blood donors in Denmark in 2010. Methods The study population comprised all Danes in the age range eligible for blood donation (N = 3,236,753) at the end of 2010. From the Scandinavian Donations and Transfusions (SCANDAT) register, we identified 174,523 persons who donated blood in Danish blood banks at least once in 2010. The association between sociodemographic characteristics and blood donor prevalence was examined using regression models. Results The overall prevalence of blood donation was 5.4% among both women and men. The age-specific prevalence of blood donation peaked at 25 years of age (6.8%) for women and 30 years of age (5.7%) for men. Children of any age were associated with lower prevalence of blood donation among women, while the opposite was seen for men. Middle to high income groups, but not the highest income group, had fourfold higher donor prevalence than the lowest income group (6.7% compared to 1.7%). The prevalence of blood donation was considerably lower among men living with their parents (2.9%) or alone (3.9%) than among men cohabitating with a woman (6.2%). Summary Social marginalization, as indicated by low income and being a male living without a woman, was associated with lower prevalence of blood donation. However, individuals with very high incomes and women with children were underrepresented in the Danish blood donor population.
