Abstract
BACKGROUND Mixed reality (MR), a form of virtual reality (VR), provides an immersive and interactive experience for the user. Given VR's benefits in patients undergoing needle insertion procedures, MR's usability, impact on anxiety, and safety were evaluated in the blood donation setting. STUDY DESIGN AND METHODS Whole blood donors ≥18 years old (yo) were enrolled at two blood centers and provided a MR headset with independently developed software to wear during blood donation. Pre- and post-donation questionnaires were conducted, and reaction data were reviewed. A post-study questionnaire was also completed by staff who assisted donors with MR. Descriptive statistics, bivariate analyses, and multinomial logistic regression were performed, and p values determined statistical significance between variables. RESULTS A total of 282 donors completed the study. 84% wanted to try MR because it seemed fun/different/cool/interesting, and most staff (69%) and donors (68%) found MR easy to use. Baseline subjective anxiety, reported by 50.3% (more often in females, first-time donors, and donors <20 yo), was reduced by MR in 68.4% of donors, and there was a 3.6 times higher odds of anxiety reduction with MR. 54% of donors with baseline anxiety would use MR again with the highest future interest in young donors. Donor reactions while using MR were mild and included pre-faint reactions and hematomas. CONCLUSION This study demonstrates the potential of MR in reducing donor anxiety, its feasibility during blood donation, and its safety in blood donors. MR is an innovative technology that holds promise to increase donor engagement, satisfaction, and retention.

Lasky B, Singh U, Young PP. Young apheresis platelet donors show significant and sustained growth over the last decade in the US, 2010-2019: A favorable sign of the resiliency of the platelet supply. Transfusion 2023. [PMID: 37191295 DOI: 10.1111/trf.17400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 04/26/2023] [Accepted: 04/26/2023] [Indexed: 05/17/2023]
Abstract
BACKGROUND Platelet demand continues to rise and US hospitals frequently face shortages. The peak median age of apheresis platelet donors (APD) is believed to have increased over the last decade, raising concerns that the APD base is not being adequately replenished with young donors. STUDY DESIGN/METHODS American Red Cross (ARC) apheresis platelet collections were evaluated from calendar years 2010 through 2019. APD, products per procedure/split rate (PPP) and donation frequencies were stratified into age groups. RESULTS/FINDINGS The number of unique APD from calendar year 2010 through 2019 in the ARC donor pool increased from 87,573 to 115,372 donors, representing a 31.7% overall growth. Donors in the 16-40 year-old (y) age group increased by 78.8% overall, with the largest absolute increases seen in the 26-30 y (4852 donors, 99.9% growth), followed by the 31-35 y (3991, 94.1%) group. Donors aged 56+ increased by 50.4% overall, with the largest increase seen in the 66-70 y (5988 donors, 108.1% growth) group. Middle-aged donors, aged 41-55 y, demonstrated a decrease of 16.5%. Over the last decade, the youngest age groups (16-40 y) comprised 61.3% of first-time donors (FTD). Annual donation frequency increased with increasing age and PPP. The highest donation frequencies were seen in the oldest age groups. CONCLUSION Although the peak median age of APD increased over the study period, relative contribution of the 16-40 y APD base also increased. Older donors exhibited the highest donation frequencies and thus contributed the largest volume of apheresis platelet units. Platelet donor activity declined in the middle age (41-55 y) group.

Abstract
Social media has the potential to encourage prosocial behaviors at scale, yet very little causal evidence exists on the impact of related efforts. Blood donation is a particularly difficult, but essential prosocial behavior that is often critically undersupplied. We examine the effect of Facebook's blood donation tool on voluntary blood donation. We partnered with four major blood banks in the United States covering 363 collection facilities in 46 states and Washington, D.C. We tracked the tool's impact on blood donations during its staggered rollout on a sample of more than 47,000 facility-date observations from March 2019 to September 2019. The tool caused an increase of 0.55 total donations per facility per day (+4.0% [95% CI: 0.04%-8.0%]), and an increase of 0.15 donations from first-time donors per facility per day (+18.9% [95% CI: 4.7%-33.1%]). Longitudinal evidence from Brazil and India suggests the share of donors who both received a message from the tool and stated they were influenced by Facebook to donate increased from 0% to 14.1% [95% CI: 12.1%-16.2%] in the first year of the tool's deployment (i.e., September 2018 to August 2019). These meaningful increases, especially from first-time donors, demonstrate that social media platforms can play an important role in fostering offline prosocial behaviors that benefit the health and well-being of societies around the world.

Blood donation motivators and barriers reported by young, first-time whole blood donors: Examining the association of reported motivators and barriers with subsequent donation behavior and potential sex, race, and ethnic group differences. Transfusion 2022; 62:2539-2554. [PMID: 36281204 PMCID: PMC9742189 DOI: 10.1111/trf.17162] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 10/11/2022] [Accepted: 10/11/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND A greater understanding of young, first-time donor motivators and barriers is needed to address the ongoing challenge of retaining these essential donors. STUDY DESIGN AND METHODS Structured interviews conducted with 508 young, first-time whole blood donors [66.1% female; Mean Age = 19.4 (SD = 2.5) years] were coded to identify reported motivators and barriers. Reported motivators and barriers were then examined for their association with attempted donation behavior over a 14-month follow-up, and for potential sex, race, and ethnic group differences in the frequency of endorsement. RESULTS Prosocial motivation (e.g., altruism) was the most commonly reported motivator and fear (e.g., fainting, needles) was the most commonly reported barrier. Donation behavior was unrelated to reported motivators, but was significantly related to four reported barriers including fear of fainting/dizziness, fear of needles/pain, having personal commitments that conflict with donating, and perceiving oneself as unsuited to donate for health reasons. Sex, racial, and ethnic differences were noted with respect to the percentages of donors reporting several donation-related motivators and barriers. CONCLUSION The present findings identify donation-related barriers that could be important targets to address in the effort to encourage new young donors and to retain these new donors for the long term. Importantly, these data also highlight the importance of considering individual differences in donor motivation as a function of sex, race, and ethnicity.

Transfusion 2022; 62:1269-1279. [PMID: 35510783 DOI: 10.1111/trf.16893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 04/04/2022] [Accepted: 04/04/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Blood centers have a dual mission to protect donors and patients; donor safety is paramount to maintaining an adequate blood supply. Elucidating donor factors associated with adverse reactions (AR) is critical to this mission. STUDY DESIGN/METHODS A retrospective cohort analysis of whole blood donors from 2003 to 2020 was conducted at a single blood center in northern California. Adjusted odds ratios (AORs) with 95% CIs for ARs were estimated via multivariable logistic regression on demographics, donation history, and physical examination data. Where appropriate, Wilcoxon-Rank Sum and chi-squared tests were used to determine significance. RESULTS First-time blood donors (FTD) exhibited a higher AR rate than repeat donors (4.4% vs. 1.9% p < .0001). When compared with FTDs without AR, FTDs with ARs (FT-AR) were less likely to return (30.0% vs. 47.3%, p < .0001), and, of those who returned, had a higher rate of reaction 20.2% versus 2.8% (p < .001). Factors found to be associated with FT-AR (younger age, increased heart rate, and higher diastolic blood pressure) still correlated positively with AR on return donation, but to a lower degree. FTD who potentially witnessed an AR had a lower return rate (44.6% vs. 47.3%, p = <.001) and donated fewer units (2.38 vs. 3.37, p < .001) when compared to FTD who did not witness an AR. CONCLUSION The AR on FTD increases the AR likelihood of return donation. Longitudinal analysis shows that a time-based deferral policy targeted at FT-AR young donors can reduce the number of ARs while not dramatically impacting the blood supply.

Abstract
BACKGROUND This study aimed to promote competence, autonomy, and relatedness among first-time whole blood donors to enhance intrinsic motivation and increase retention. STUDY DESIGN AND METHODS Using a full factorial design, first-time donors (N = 2002) were randomly assigned to a no-treatment control condition or to one of seven intervention conditions designed to promote donation competence, autonomy, relatedness, a combination of two (e.g., competence and autonomy), or all three constructs. Participants completed donor motivation measures before the intervention and 6 weeks later, and subsequent donation attempts were assessed for 1 year. RESULTS There was no significant group difference in the frequency of donation attempts or in the number of days to return. Significant effects of group were observed for 10 of the 12 motivation measures, although follow-up analyses revealed significant differences from the control group were restricted to interventions that included an autonomy component. Path analyses confirmed direct associations between interventions involving autonomy and donor motivation, and indirect mediation of donation attempts via stronger donation intentions and lower donation anxiety. CONCLUSION Among young, first-time, whole blood donors, brief interventions that include support for donor autonomy were associated with direct effects on donor motivation and indirect, but small, effects on subsequent donation behavior.

Abstract
BACKGROUND Adverse donor events (ADEs) are usually mild and short-term with no sequelae, but may cause disinclination toward future donations. AIMS To determine the impact of delayed ADEs (D-ADEs) in addition to immediate ADEs (I-ADEs) on the intention of future donations (IFDs) and to analyze the various associated factors. METHODS ADEs were categorized following the ISBT working group on donor vigilance. Telephonic interviews of the donors were conducted 2 weeks after the whole blood (WB) and plateletpheresis donation to inquire about D-ADEs and IFDs. RESULTS A total of 3514 WB and 531 plateletpheresis donors were included in the study. WB donors had an overall higher IFD as compared to plateletpheresis donors (89.53% vs 57.06%, P < .001). A higher IFD was observed in male WB donors as compared to female WB donors (89.95% vs 75%, P < .001). Repeat WB donors had a higher IFD as compared with first-time donors (93.66% vs 81.37%, P < .001). A total of 13.7% WB donors and 19.2% plateletpheresis donors reported D-ADEs. WB donors who experienced D-ADEs had a significantly lower IFD (78.38% vs 91.63%, P < .001) as compared with donors without any ADEs; a similar trend was observed in donors who experienced I-ADEs (69.90% vs 91.63%, P < .001). In WB donors, systemic D-ADEs such as fatigue had a more negative impact on IFDs as compared with localized D-ADEs such as bruises (63.93% vs 86.83%, P < .001). CONCLUSIONS Both D-ADEs and I-ADEs negatively impact donors' intention to donate again. Systemic D-ADEs had a more negative impact on IFDs as compared with localized D-ADEs.

Long-term return and donation pattern of those who begin donating at different ages: A retrospective cohort analysis of blood donors in Australia. Transfusion 2020; 61:799-810.

Abstract
BACKGROUND This study compared the likelihood of return to donate and donation rate ratio by age of donors at their first donation when followed up to 12 years. STUDY DESIGN AND METHODS Donation history of two cohorts of first-time donors (those donating in 2007 and 2013) was extracted until March 2019 from Australian Red Cross Lifeblood's national database. Poisson regression analyses compared donor return and negative-binomial regression estimated the rate ratio of donations. RESULTS A total of 120 469 and 95 381 donors were included in the 2007 and 2013 cohorts, respectively. Compared to donors aged 20-24 years, the likelihood of return in both cohorts increased consistently as age at first donation increased from 30-years and above. Average number of whole-blood and plasmapheresis donations increased as the age at first donation increased from 30-years onward. The whole-blood donation rate was highest for donors ≥60 years, while plasmapheresis donation rate was highest for donors aged 50-59 years. These patterns were largely consistent when stratified by sex. CONCLUSIONS To continuously ensure the short- to mid-term sufficiency of blood supply in Australia, targeted recruitment of donors aged 30-years and above may be considered, however its feasibility and impact should be explored further given relatively smaller proportion of new donors are middle-aged and older under current policies. Future studies with a longer follow-up period are needed to examine whether the frequency of donation among those who start donating at a younger age increases later in their life when they are 30-years or over.

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.

Sociodemographic and behavioral characteristics associated with blood donation in the United States: a population-based study. Transfusion 2019; 59:2899-2907. [PMID: 31222779 DOI: 10.1111/trf.15415] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2019] [Revised: 05/22/2019] [Accepted: 05/22/2019] [Indexed: 01/28/2023]
Abstract
BACKGROUND Contemporary population-based data on characteristics associated with blood donation in the United States (U.S.) are limited. STUDY DESIGN AND METHODS A cross-sectional analysis was performed among 28,739 persons aged 18 years and older who participated in the 2016 National Health Interview Survey, a household survey of the noninstitutionalized U.S. civilian population. Analyses were weighted and accounted for the complex survey design. Adjusted prevalence ratios (aPR) were estimated by multivariable log-binomial regression. RESULTS The percentage of individuals reporting a past-year history of blood donation was 5.7% (95% confidence interval [CI], 5.3%-6.1%) and was highest in the youngest age group (18-24 years, 8.4%). A past-year history of blood donation was more common in males compared to females (6.3% vs. 5.1%; aPR, 1.12 [95% CI, 0.99-1.27]) and those born in the U.S. compared to individuals born outside the U.S. (6.4% vs. 2.4%; aPR, 1.92 [95% CI, 1.49-2.47]). The percentage of individuals with a past-year history of blood donation was significantly lower in blacks (3.9%; aPR, 0.60 [95% CI, 0.47-0.75]) and Hispanics (3.0%; aPR, 0.63 [95% CI, 0.48-0.83]) in comparison to whites (6.9%). Being a college graduate, being employed, being physically active, and never being a cigarette smoker were factors positively associated with blood donation. The percentage of individuals with a past-year history of blood donation varied by geographic census region, with prevalence being higher in the Midwest (7.3%) and South (6.0%) compared to the Northeast (4.7%) and West (4.4%). CONCLUSION Continued differences in the blood donor population with reference to the U.S. population underscore the need to understand barriers or deterrents to blood donation. Evidence-based donor recruitment and related policies remain imperative to ensure that there is a sustainable blood supply.

Individual, contextual and network characteristics of blood donors and non-donors: a systematic review of recent literature. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2017; 15:382-397. [PMID: 28686151 DOI: 10.2450/2017.0064-17] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 02/28/2017] [Accepted: 04/20/2017] [Indexed: 11/21/2022]
Abstract
BACKGROUND The ageing population and recent migration flows may negatively affect the blood supply in the long term, increasing the importance of targeted recruitment and retention strategies to address donors. This review sought to identify individual, network and contextual characteristics related to blood donor status and behaviour, to systematically discuss differences between study results, and to identify possible factors to target in recruitment and retention efforts. METHODS The systematic review was conducted in accordance with a predefined PROSPERO protocol (CRD42016039591). After quality assessments by multiple independent raters, a final set of 66 peer-reviewed papers, published between October 2009 and January 2017, were included for review. RESULTS Individual and contextual characteristics of blood donor status and behaviour were categorised into five main lines of research: donor demographics, motivations and barriers, adverse reactions and deferral, contextual factors, and blood centre factors. Results on donor demographics, motivations and barriers, and contextual factors were inconclusive, differing between studies, countries, and sample characteristics. Adverse reactions and deferral were negatively related to blood donor behaviour. Blood centre factors play an important role in donor management, e.g., providing information, reminders, and (non-)monetary rewards. No studies were found on network characteristics of (non-)donors. DISCUSSION Although individual and contextual characteristics strongly relate to blood donor status and behaviour, mechanisms underlying these relations have not been studied sufficiently. We want to stress the importance of longitudinal studies in donor behaviour, exploring the role of life events and network characteristics within blood donor careers. Increased understanding of donor behaviour will assist policy makers of blood collection agencies, with the ultimate goal of safeguarding a sufficient and matching blood supply.

Abstract
Two studies explored how self-based cues (i.e., self-efficacy), socially-based cues (i.e., perceived social norms), and prior blood donation experience differentially influence behavioral intentions. In Study 1, undergraduate students (N = 766) completed an online study that evaluated prior experiences, self-efficacy, perceived norms, and behavioral intentions in the context of blood donation. In Study 2, a community sample (N = 199) from a clinic waiting room completed similar measures. Across both studies, having high self-efficacy was a necessary and sufficient antecedent to high intentions, regardless of norm perception for donors. For non-donors, however, high self-efficacy was necessary but not sufficient; non-donors' intentions were higher when giving blood was perceived to be normative, but far lower when it was not. When self-efficacy was low, the effects of experience and norms did not exert meaningful effects and donation intentions were quite low. These results demonstrate that the impact of self-based and socially-based cues on behavioral intentions may differ as a function of experience. The findings can inform public health initiatives and enhance the accuracy of theoretical models by directly examining experience as a moderator.

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.

Applying self-determination theory to the blood donation context: The blood donor competence, autonomy, and relatedness enhancement (Blood Donor CARE) trial. Contemp Clin Trials 2016; 53:44-51. [PMID: 27979752 DOI: 10.1016/j.cct.2016.12.010] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Revised: 11/29/2016] [Accepted: 12/03/2016] [Indexed: 12/18/2022]
Abstract
The Blood Donor Competency, Autonomy, and Relatedness Enhancement (Blood Donor CARE) project was designed as a practical application of self-determination theory to encourage retention of first-time donors. Self-determination theory proposes that people are more likely to persist with behaviors that are internally-motivated, and that externally-motivated behavior can evolve and become internalized given the appropriate socio-environmental conditions. According to self-determination theory, motivation to engage in blood donation may become increasingly self-determined if the behavior satisfies fundamental human needs for competence (a sense of self-efficacy to achieve specific goals), autonomy (a sense of volitional control over one's behavior), and relatedness (a sense of connection to a larger group). The primary aim of this randomized controlled trial is to examine the effect of competence, autonomy, and/or relatedness interventions on donor retention. Using a full factorial design, first-time donors will be assigned to a control condition or one of seven intervention conditions. Donation competence, autonomy, and relatedness, along with additional constructs associated with return donation, will be assessed before and after the intervention using online surveys, and donation attempts will be tracked for one-year using blood center donor databases. We hypothesize that, compared to the control condition, the interventions will increase the likelihood of a subsequent donation attempt. We will also examine intervention-specific increases in competence, autonomy, and relatedness as potential mediators of enhanced donor retention. By promoting first-time donor competence, autonomy, and relatedness our goal is to enhance internal motivation for giving and in so doing increase the likelihood of future donation.

Abstract
BACKGROUND In contrast to standard donor retention strategies (e.g., mailings, phone calls, text messages), we developed a brief telephone interview, based on motivational interviewing principles, that encourages blood donors to reflect upon their unique motivators and barriers for giving. This study examined the effect of this motivational interview, combined with action and coping plan components, on blood donor motivations. STUDY DESIGN AND METHODS The design was to randomly assign blood donors to receive either a telephone-delivered motivational interview with action and coping plan components or a control call approximately 6 weeks after their most recent donation. Participants completed a series of surveys related to donation motivation approximately 3 weeks before telephone contact (precall baseline) and then repeated these surveys approximately 1 week after telephone contact (postcall). RESULTS The sample was 63% female, included a majority (52.6%) of first-time blood donors, and had a mean age of 30.0 years (SD, 11.7 years). A series of analyses of variance revealed that, relative to controls (n = 244), donors in the motivational interview group (n = 254) had significantly larger increases in motivational autonomy (p = 0.001), affective attitude (p = 0.004), self-efficacy (p = 0.03), anticipated regret (p = 0.001), and intention (p = < 0.001), as well as larger decreases in donation anxiety (p = 0.01), from precall baseline to postcall assessment. CONCLUSION This study supports motivational interviewing with action and coping planning as a novel strategy to promote key contributors to donor motivation.

Abstract
OBJECTIVE The aim of this study is to enhance the understanding of frequent blood donors' characteristics and devise strategies to achieve an optimal blood inventory. BACKGROUND Apart from donor recruitment and retention, an effective way to increase blood supply is to increase the donation frequency among donors. Understanding the characteristics of frequent donors will be helpful to impact their future donation pattern, which would in turn achieve a stable and adequate blood inventory to meet the changing demands of the society. METHODS AND MATERIALS Demographic information of blood donors for each donation in Hong Kong (HK) was routinely collected and stored in the database of Hong Kong Red Cross Blood Transfusion Service. Logistic regression models (by gender group) with interaction effects were constructed to analyse the differences in the likelihood of being frequent donors and the associations with their demographic characteristics. RESULTS A total of 158,666 blood donors in 2010 gave 227,634 donations during the study. In general, male donors were more likely to be frequent donors. Logistic regression models further identified the characteristics of frequent donors in HK: older, blood type Rh D-ve and repeat donors, although their extent of impact was different for different gender group. CONCLUSION To achieve an optimal blood inventory to meet the challenge of ageing in the society, donors who donate less often should be targeted to increase their donation frequency. More efforts in promotion should be made to recruit those non-donors to join the blood donation pool and motivate 'targeted' existing donors in the population to participate blood donation more regularly.

Abstract
First-time blood donors are essential to the US donor pool, providing nearly a third of all donations. Unfortunately, there are a wide variety of obstacles to repeat donation and new donors are extremely difficult to retain. Because each donor experiences a unique set of deterrents, we developed a post-donation interview based on motivational interview principles in order to flexibly address individual barriers. The primary aim of this randomized clinical trial is to examine retention of first-time, group O blood donors who are randomly assigned to receive either a telephone-delivered interview with motivational and action planning components or a standard-of-care control call approximately six weeks after their donation. Measures of donation attitude, perceived behavioral control, intention, and motivational autonomy will be measured before and after the telephone contact using online surveys, and donation attempts will be tracked for one year using blood center donor databases. We hypothesize that, compared to controls, donors who receive the telephone interview will be more likely to make a donation attempt over the following year. In addition, we will examine possible mechanisms of action of the interview using key predictors of donation behavior as described by Self Determination Theory (i.e., motivational autonomy) and the Theory of Planned Behavior (i.e., attitude, perceived behavioral control, and intention). Results of this intervention may help to support a novel strategy to enhance retention of selected blood donors in an effort to better meet the nation's blood supply needs.

Abstract
BACKGROUND To date, most studies on deferral of blood donors have focused on men who have sex with men (MSM) and/or injecting drug users. Few have examined deferrable risk behaviors relating to transfusion-transmissible infections (TTIs) in general. This study aimed to examine the prevalence of, and factors associated with, nondisclosure of TTI-related risk behaviors in donors. STUDY DESIGN AND METHODS Chinese-speaking donors who had just given blood in Hong Kong were invited to self-complete an anonymous questionnaire. Practices of one or more of seven deferrable risk behaviors associated with TTI were inquired. Factors associated with noncompliance with self-disclosure were evaluated by logistic regression. RESULTS Over a 4-week study period in 2012, a total of 1143 donors were recruited. Overall, 0.2% gave a history of drug injection, 1.7% had had sex with sex worker(s), and 0.3% had had sex with a human immunodeficiency virus–infected partner, while none had been paid for sex. Some 1.5% of male donors reported having same-sex behaviors. Factors associated with noncompliance were male gender (odds ratio [OR] 31.1; 95% confidence interval [CI], 3.7-263.6), having multiple sex partners (OR, 89.7; 95% CI, 28.7-279.9), and previous history of temporary deferral (OR, 11.4; 95% CI, 2.5-53.3). If suspected noncompliance was included, the overall prevalence of nondisclosure of deferrable behaviors could be high at 6.5%. CONCLUSION Albeit uncommon, some donors fail to provide accurate answers to predonation screening questions and are not deferred appropriately. There is room for improvement to make deferral policy acceptable and understandable, so as to minimize the risk of TTI. Efforts are also needed to tackle the paucity of data on noncompliance of non-MSM donors.

BACKGROUND Infectious window period donations slip through routine donor screening procedures. To explore the potential value of predonation screening of candidate donors, we compared the proportion of incident transfusion-transmissible infections in candidate donors, in first-time donors, and in repeat donors. STUDY DESIGN AND METHODS A retrospective analysis was performed of all incident hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections in candidate, first-time, and repeat donors in the Netherlands during the period 2009 to 2013. RESULTS In total, 176,716 candidate donors, 144,226 first-time donations, and 4,143,455 repeat donations were screened for HBV, HCV, and HIV infection. Acute HBV infection was identified in the predonation sample of six candidate donors. One first-time donor, testing HIV-negative at predonation screening, tested positive for anti-HIV and HIV RNA in the first donation 29 days later. Among repeat donations we identified 15, one, and six incident HBV, HCV and HIV infections, respectively. The proportion of incident infections among candidate donors/first-time donations/repeat donations was for HBV, 3.40/0/0.36; for HCV, 0/0/0.02; and for HIV 0/0.69/0.14 per 100,000, respectively. CONCLUSION Predonation screening of candidate donors very likely causes a loss of donations, but it might prevent undetected window period donations. Further studies are necessary to determine the value of predonation screening as an additional safety measure.

Abstract
Background Seasonal distribution of blood donation hinders efforts to provide a safe and
adequate blood supply leading to chronic and persistent shortages. This study
examined whether holidays, geographical area and donation type (community versus
replacement) has any impact on the fluctuation of donations. Methods The numbers of blood donations from 2007 through 2010 in three Brazilian
Retrovirus Epidemiological Donor Study II (REDS-II) participating centers were
analyzed according to the week of donation. The weeks were classified as holiday
or non-holiday. To compare donations performed during holiday versus non-holiday
weeks, tabulations and descriptive statistics for weekly donations by blood center
were examined and time series analysis was conducted. Results The average weekly number of donations varied according to the blood center and
type of week. The average number of donations decreased significantly during
Carnival and Christmas and increased during the Brazilian National Donor Week. The
fluctuation was more pronounced in Recife and Belo Horizonte when compared to
São Paulo and higher among community donors. Conclusion National bank holidays affect the blood supply by reducing available blood
donations. Blood banks should take into account these oscillations in order to
plan local campaigns, aiming at maintaining the blood supply at acceptable
levels.

Risk factors for complications in donors at first and repeat whole blood donation: a cohort study with assessment of the impact on donor return. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2013; 12 Suppl 1:s28-36. [PMID: 23867173 DOI: 10.2450/2013.0262-12] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 11/17/2012] [Accepted: 02/28/2013] [Indexed: 11/21/2022]
Abstract
BACKGROUND First-time donation is among recognised risk factors for vasovagal reactions to blood donation and reactions are known to reduce donor return. We assessed associations between potential risk factors and vasovagal reactions and needle-related complications in first-time whole blood donation in comparison to repeat donation and analysed the impact of complications on donor return. MATERIALS AND METHODS We performed a cohort study on whole blood donations in The Netherlands from 1/1/2010 to 31/12/2010 using data extracted from the blood service information system. Donation data up to 31/12/2011 were used to ascertain donor return. RESULTS In 2010 28,786 donors made first whole blood donations and there were 522,958 repeat donations. Vasovagal reactions occurred in 3.9% of first donations by males and 3.5% of first donations by females compared to in 0.2% and 0.6%, respectively, of repeat donations. Associations of vasovagal reactions with other factors including age, body weight, systolic and diastolic blood pressure were similar in first-time and repeat donors. Needle-related complications occurred in 0.2% of male and 0.5% of female first-time donations and in 0.1% and 0.3%, respectively, of repeat donations. Among first-time donors, the return rate within 1 year was 82% following an uncomplicated first donation, but 55% and 61% following vasovagal reactions and needle-related complications, respectively; the corresponding percentages among repeat donors were 86%, 58% and 82%. DISCUSSION Among first-time donors, females suffered less than males from vasovagal reactions. Other risk factors had similar associations among first-time and repeat donors. Vasovagal reactions and needle-related complications in both first-time and repeat donors are followed by reduced donor return.

Abstract
BACKGROUND Blood centers rely heavily on adolescent donors to meet blood demand, but presyncope and syncope are more frequent in younger donors. Studies have suggested administration of water before donation may reduce syncope and/or presyncope in this group. STUDY DESIGN AND METHODS We conducted a randomized, controlled trial to establish the effect of preloading with 500 mL of water on the rate of syncope and presyncope in adolescent donors. School collection sites in Eastern Cape Province of South Africa were randomized to receive water or not. Incidence of syncope and presyncope was compared between randomization groups using multivariable logistic regression. RESULTS Of 2464 study participants, 1337 received water and 1127 did not; groups differed slightly by sex and race. Syncope or presyncope was seen in 23 (1.7%) of the treatment and 18 (1.6%) of the control arm subjects. After adjusting for race, sex, age, and donation history, there was no difference in outcome between the water versus no water arms (adjusted odds ratio [OR], 0.80; 95% confidence interval [CI], 0.42-1.53). Black donors had sevenfold lower odds of syncope or presyncope than their white counterparts (adjusted OR, 0.14; 95% CI, 0.04-0.47). CONCLUSION Preloading adolescent donors with 500 mL of water did not have a major effect in reducing syncope and presyncope in South African adolescent donors. Our adolescent donors had lower overall syncope and presyncope rates than similar populations in the United States, limiting the statistical power of the study. We confirmed much lower rates of syncope and presyncope among young black donors.

Abstract
Résumé
Les travaux sur le don de sang ont jusqu’à maintenant privilégié l’étude des variables individuelles d’un point de vue démographique et psychologique (les motivations au don, par exemple). Pourtant, les notions actuelles de géographie sociale et de la santé sont tout à fait à propos pour l’étude des donneurs de sang québécois. Cette étude vise trois objectifs principaux : 1) analyser la répartition spatiale des dons de sang au Québec ; 2) analyser les distances séparant les lieux de résidence des lieux de collecte ; 3) mettre en relation le profil sociodémographique des municipalités régionales de comté (MRC) avec les nombres de donneurs et les fréquences de dons de sang. La méthode fait appel aux systèmes d’information géographique et à la statistique descriptive (corrélation, analyse de classification) pour explorer la géodémographie du don de sang sur une période de cinq ans (2003-2008). Les résultats mettent en valeur le rôle de certaines variations régionales entre les milieux urbains et ruraux et démontrent l’apport important des banlieues dans la réserve collective de sang. À partir de ces constats, certaines pistes de réflexion et d’action sont avancées, toutes en lien avec l’objectif ultime d’assurer un approvisionnement de sang continu et à long terme.

Abstract
The primary focus of national blood programs is the provision of a safe and adequate blood supply. This goal is dependent on regular voluntary donations and a regulatory infrastructure that establishes and enforces standards for blood safety. Progress in ex vivo expansion of blood cells from cell sources including peripheral blood, cord blood, induced pluripotent stem cells, and human embryonic stem cell lines will likely make alternative transfusion products available for clinical use in the near future. Initially, alloimmunized patients and individuals with rare blood types are most likely to benefit from alternative products. However, in developed nations voluntary blood donations are projected to be inadequate in the future as blood usage by individuals 60 years and older increases. In developing nations economic and political challenges may impede progress in attaining self-sufficiency. Under these circumstances, ex vivo generated red cells may be needed to supplement the general blood supply.

Abstract
BACKGROUND In Brazil, most donations come from repeat donors, but there are little data on return behavior of donors. STUDY DESIGN AND METHODS Donors who made at least one whole blood donation in 2007 were followed for 2 years using a large multicenter research database. Donation frequency, interdonation intervals, and their association with donor demographics, status, and type of donation were examined among three large blood centers in Brazil, two in the southeast and one in the northeast. RESULTS In 2007, of 306,770 allogeneic donations, 38.9% came from 95,127 first-time donors and 61.1% from 149,664 repeat donors. Through December 31, 2009, a total of 28.1% of first-time donors and 56.5% of repeat donors had donated again. Overall, the median interdonation interval was approximately 6 months. Among men it was 182 and 171 days for first-time and repeat donors, and among women, 212 and 200 days. Predictors of return behavior among first-time donors were male sex (odds ratio [OR], 1.17; 95% confidence interval [CI], 1.13-1.20), community donation (OR, 2.26; 95% CI, 2.20-2.33), and age 24 years or less (OR, 0.62-0.89 for donors ≥ 25 years). Among repeat donors predictors were male sex (OR, 1.35; 95% CI, 1.32-1.39), age 35 years or more (OR, 1.08-1.18 vs. ≤ 24 years), and community donation (OR, 2.39; 95% CI, 2.33-2.44). Differences in return by geographic region were evident with higher return rates in the northeast of Brazil. CONCLUSION These data highlight the need to develop improved communication strategies for first-time and replacement donors to convert them into repeat community donors.

Abstract
BACKGROUND Brazilian blood centers ask candidate blood donors about the number of sexual partners in the past 12 months. Candidates who report a number over the limit are deferred. We studied the implications of this practice on blood safety. STUDY DESIGN AND METHODS We analyzed demographic characteristics, number of heterosexual partners, and disease marker rates among 689,868 donations from three Brazilian centers between July 2007 and December 2009. Donors were grouped based on maximum number of partners allowed in the past 12 months for each center. Chi-square and logistic regression analysis were conducted to examine associations between demographic characteristics, number of sex partners, and individual and overall positive markers rates for human immunodeficiency virus (HIV), human T-lymphotropic virus Types 1 and 2, hepatitis B virus, hepatitis C virus, and syphilis. RESULTS First-time, younger, and more educated donors were associated with a higher number of recent sexual partners, as was male sex in São Paulo and Recife (p<0.001). Serologic markers for HIV and syphilis and overall were associated with multiple partners in São Paulo and Recife (p<0.001), but not in Belo Horizonte (p=0.05, p=0.94, and p=0.75, respectively). In logistic regression analysis, number of recent sexual partners was associated with positive serologic markers (adjusted odds ratio [AOR], 1.2-1.5), especially HIV (AOR, 1.9-4.4). CONCLUSIONS Number of recent heterosexual partners was associated with HIV positivity and overall rates of serologic markers of sexually transmitted infections. The association was not consistent across centers, making it difficult to define the best cutoff value. These findings suggest the use of recent heterosexual contacts as a potentially important deferral criterion to improve blood safety in Brazil.

Abstract
BACKGROUND This study investigated the effect of blood donation environment, fixed or mobile with differing sponsor types, on donation return time. STUDY DESIGN AND METHODS Data from 2006 through 2009 at six US blood centers participating in the Retrovirus Epidemiology Donor Study-II (REDS-II) were used for analysis. Descriptive statistics stratified by whole blood (WB), plateletpheresis (PP), and double red blood cell (R2) donations were obtained for fixed and mobile locations, including median number of donations and median interdonation interval. A survival analysis estimated median return time at fixed and mobile sites, while controlling for censored return times, demographics, blood center, and mandatory recovery times. RESULTS Two-thirds (67.9%) of WB donations were made at mobile sites, 97.4% of PP donations were made at fixed sites, and R2 donations were equally distributed between fixed and mobile locations. For donations at fixed sites only or alternating between fixed and mobile sites, the highest median numbers of donations were nine and eight, respectively, and the shortest model-adjusted median return times (controlling for mandatory eligibility times of 56 and 112 days) were 36 and 30 days for WB and R2 donations, respectively. For PP donations, the shortest model-adjusted median return time was 23 days at a fixed location and the longest was 693 days at community locations. CONCLUSION WB, PP, and R2 donors with the shortest time between donations were associated with fixed locations and those alternating between fixed and mobile locations, even after controlling for differing mandatory recovery times for the different blood donation procedures.

Abstract
BACKGROUND The importance of adverse reactions in terms of donor safety recently has received significant attention, but their role in subsequent donation behavior has not been thoroughly investigated. STUDY DESIGN AND METHODS Six REDS-II blood centers provided data for this analysis. Summary minor and major adverse reaction categories were created. The influence of adverse reactions on donation was examined in two ways: Kaplan-Meier curves were generated to determine the cumulative pattern of first return, and adjusted odds ratios (AORs) for demographic and other factors positively and negatively associated with return were estimated using multivariable logistic regression. RESULTS Donors who had major reactions had longer times to return than donors with minor or no reactions. The AOR of returning for donors with major reactions was 0.32 (95% confidence interval [CI], 0.28-0.37) and with minor reactions 0.59 (95% CI, 0.56-0.62) when compared to donors who did not have reactions. Conversely, the most important factors positively associated with return were the number of donations in the previous year and increasing age. Subsequent return, whether a major, minor, or no reaction occurred, varied by blood center. Factors that are associated with the risk of having adverse reactions were not substantial influences on the return after adverse reactions. CONCLUSION Having an adverse reaction leads to significantly lower odds of subsequent donation irrespective of previous donation history. Factors that have been associated with a greater risk of adverse reactions were not important positive or negative predictors of return after a reaction.

Abstract
BACKGROUND It is important to understand donor return behavior. Converting first-time donors to become repeat donors is essential for maintaining an adequate blood supply. STUDY DESIGN AND METHODS Characteristics of 241,552 whole blood (WB) donations from first-time and repeat donors who donated in 2008 at the five blood centers in China were compared. A subset of 54,394 WB donors who donated between January 1 and March 31, 2008, were analyzed for their return behavior in 2008 after the index donation using logistic regression. RESULTS Of all donations, 64% were from first-time donors. Donors with self-reported previous donations tended to be male, older, and married; donated larger volume (≥ 300 mL); and were heavier in weight. Among donors who donated from January to March 2008, 14% returned for subsequent WB donations by the end of 2008. The number of previous donations and blood collection location were the two strongest predictors for making subsequent donations. Donors with one, two to three, and more than three previous donations were 3.7, 5.7, and 11.0 times more likely to return than first-time donors. Those who donated in a blood collection vehicle were four times more likely to return than those who donated at a blood center. Being female, younger, and of a lower education level (middle school or less) were positively associated with subsequent return blood donation during the follow-up period observed in this study. CONCLUSION Most of the Chinese blood supply is from first-time donors. Strategies aimed at encouraging current donors to become repeat donors are needed.

Abstract
BACKGROUND Blood banks have large altruistic donor populations and existing infrastructure that make them attractive sites for genetic epidemiologic research, but donors' willingness to participate and the impact on blood donation are unknown. STUDY DESIGN AND METHODS A total of 2162 blood donors in Northern California responded to a cross-sectional questionnaire in August and September 2007. Participants were asked their likelihood of participation and future blood donation under three different scenarios: identity-linked genetic research, identity-unlinked genetic research, and genetic testing as a service. RESULTS The majority of blood donors indicated that they would be likely or very likely to participate in identity-linked genetic research (67%) and in identity-unlinked genetic research (54%). While older donors and more frequent donors were more likely to participate in identity-linked research, younger, Caucasian, more educated, and more frequent donors were more likely to participate in identity-unlinked research. Less than 10% of donors indicated they would be less likely to donate blood in the future if genetic research was conducted at blood banks. More than 75% of donors would be interested in genetic testing as an optional service at the blood bank, but more than 20% of donors would be less likely to donate if such a service was offered. CONCLUSION Overall, we found that the majority of blood donors would be likely to participate in genetic research and that less than 10% would be less inclined to donate if such research was conducted by blood banks.
