Effective ways to retain first‐time blood donors: a field‐trial study

The effectiveness of telephone surveys on the return of first-time donors: A randomized controlled trial

BACKGROUND

The management of blood supply depends, among other factors, on the effective remobilization of first-time donors (FTDs). This study investigates the efficacy of telephone calls to increase second donation rates.

STUDY DESIGN AND METHODS

A randomized controlled trial was conducted on 418 first-time blood donors. In the telephone group (TG, n = 206), men were contacted 9-10 and women 13-14 weeks after their first donation. They were asked about satisfaction and intention to return, and offered an appointment. The primary outcome was the return rate within 6 months after the first donation.

RESULTS

The mean age was 28.8 ± 10.0 years and 59.9% of FTDs were female. In the TG, 89.3% were reached. Approximately 50% of each group had donated a second time by 24.2 weeks for the control group (CG) and 14.8 weeks for the TG. The six-month return rate was 65.0% in the TG and 54.3% in the CG (95%-CI [0.9%; 20.6%]; p = .033). The restricted mean time to return within 6 months was 19.4 weeks in the CG compared to 17.2 weeks in the TG (95%-CI [0.7; 3.7]; p = .004). The intervention effect tended to be larger in men than in women.

DISCUSSION

Contacting FTDs by phone after their first donation increases the six-month return rate and reduces the interval to a second donation. Male donors appear to be more receptive to this intervention. Whether the effect of the intervention helps to establish a donor identity in the long term should be the subject of further studies.

Paths to improve voluntary blood donation in mixed public/private blood donation systems such as in Lebanon?

BACKGROUND

The World Health Organization advocates for the achievement of 100% voluntary non-remunerated blood donation (VNRD) globally by the year 2020. However, until today, little was known in Lebanon regarding its actual rate or influencing factors, particularly donor motivations and behaviors. Therefore, the aim of this study was to assess the knowledge, attitudes, and practices of blood donors in Lebanon. The ultimate goals were to retain first-time donors, encourage them to become regular ones, and facilitate the transition from replacement donation to VNRD.

MATERIALS AND METHODS

A multi-centric cross-sectional study was carried across the five governorates in Lebanon. A self-administered and structured questionnaire was used in this survey. Results were presented in terms of odds ratios, with statistical significance defined at a P value of 0.05 and a 95% confidence interval. Additionally, a benchmarking analysis of the situation of blood donation in Lebanon was also conducted, identifying several areas for improvement.

RESULTS

A total of 620 blood donors participated in this study, with 21.3% being first-time donors and 78.7% repeat donors. While the latter were primarily motivated by self-esteem, solidarity or returning a favor (89%, 77.9% and 78.1%), the main obstacle for becoming regular donors was a lack of initiative (34.6%). Female donors (9.9% of the total) exhibited better knowledge (OR = 2.20, p = 0.011) and were more inclined to donate voluntarily (OR = 1.52, p = 0.048). Conversely, male donors were more likely to be repeat donors, often through replacement donation (OR = 2.95, p = 0.001).

CONCLUSION

There is a significant disparity between the low rate of voluntary donation in Lebanon (22.2%) and the relatively high proportion of donors with adequate knowledge of the donation process (60.5%). Therefore, urgent action by public authorities, based on the evidence based strategies outlined in this article, is crucial to enhancing the voluntary donation rate in Lebanon.

The return rate of deferred blood donors in Iran

BACKGROUND AND OBJECTIVES

The process of selecting blood donors is crucial for keeping the health of donors and ensuring the safety of the blood supply. However, it may create unpleasant feeling in those who are deferred. In this study, we aim to explore the return rates of Iranian deferred donors in comparison with eligible donors.

MATERIALS AND METHODS

The study included all whole blood donors referred between March 2017 and March 2018, who experienced temporary deferral for any reason. Donors who successfully donated blood during this period were also part of the study. Participants were followed up until their next donation attempt, spanning 4.8 years after initial inclusion. Then odds of return and median return time for both deferred and eligible donors were calculated.

RESULTS

From 993,824 volunteers, 733,153 (73.77%) were eligible and 192,332 (19.35%) temporary deferred. The return rate in the eligible and deferred donors was 74.77% vs. 51.77%, respectively (OR:2.78; 99%CI: 2.71-2.81). Odds of return among deferred regular (OR = 7.02, 99%CI:6.64-7.42), men (OR: 2.57, 99%CI:2.45-2.69), and over 45 years (OR: 1.15, 99% CI: 1.09-1.20), was higher than first-time, women, and younger donors. The median return time for eligible and deferred donors was 315 (99%CI: 313-316) and 1,467(99%CI: 1,412-1,524) days, respectively.

CONCLUSION

This study revealed the negative effect of deferral on the return rate, that led to a 23% reduction in the return of deferred donors. Avoiding unnecessary deferral through adherence to the standard operating procedure of donor selection and effective counselling which clarifies the purpose of deferral and encourages them to return after the deferral period ends are recommended.

Short- and long-term effects of incentives on prosocial behavior: The case of ride vouchers to a blood collection agency

This study addresses the challenge of low blood donation rates in developing countries by examining the effectiveness of a barrier-removal incentive-a one-day transportation voucher-to promote blood donation. Utilizing a longitudinal dataset of 23,750 donors from a Brazilian blood collection agency (BCA) collected between March 2018 and May 2020, we examine the short and long-term effects of this campaign on donation rates. Our results show that the incentive had a large positive influence on both donation attempts and successful donations on the day of the campaign. However, the short-term success of the intervention had an unintended consequence: the significant increase in prospective donors' waiting time at the BCA during the intervention day, which may help explain the negative impact on return rates in the 24-month follow-up. Despite these opposing outcomes, the net effect of the one-day blood donation incentive was still positive, offering valuable insights for BCAs aiming to enhance donor recruitment and retention strategies and emphasizing the need to balance immediate benefits with potential long-term impacts.

A survey assessing knowledge and attitude about blood donation among blood donors in Jordan

Background

Recruitment of low risk blood donors can be challenging. Efforts should be made to increase the level of awareness and positive attitude towards blood donation. An essential step to achieve this is obtaining comprehensive data about the current situation of awareness, knowledge and attitudes of the population towards blood donation.

Methods/materials

The present study was conducted at two blood donation centres in Amman, Jordan, during 2021. A total of 536 whole blood donors were included. Data regarding their demographic characteristics, blood donation history as well as their knowledge and attitudes regarding blood donation were collected by a questionnaire.

Results

Four hundred ninety participants (91.4%) were males, whereas only 46 participants (8.6%) were females. Ninety seven subjects (18.1%) were first time donors, whereas 431 subjects (81.9%) had previous donations. The participants' median score in the knowledge section was 19.0 points (range 5-25 points). Based on a cut-off of 15 out of 28: 84% of the participants were knowledgeable. Similarly 97% of the participants had a positive attitude based on a cut-off of 17 out of 32 points. Multivariate analysis revealed that high knowledge score was significantly associated with study major and employment status, whereas a positive attitude was significantly associated with a higher income. More than half of first time donors stated lack of awareness as being the reason for not donating blood before.

Conclusion

Measures to improve awareness, knowledge and attitudes towards blood donation should be implemented in order to meet the increasing demand for blood and blood components. Targeted campaigns, correction of some misconceptions and using different motivations are suggested.

The impact of pre-donation viral markers screening of new blood donors on blood safety

BACKGROUND

The risk of transfusion-transmissible infections (TTIs) remains a concern in transfusion medicine. Since the rate of infection among first-time blood donors is higher than repeated donors, strategies to enhance blood safety can focus on new donors. The aim of the study was to investigate the effect of pre-donation viral screening of new donors on blood safety.

METHODS AND MATERIALS

The pre-donation screening of new donors was implemented in the Kurdistan blood center. In this program, new donors who met the blood donation criteria were informed about the program and only a blood sample was donated for HBs Ag, HCV Ab, and HIV Ab testing. New donors with negative results were invited to donate blood after 12 weeks. A unit of blood was collected from eligible returned donors. Laboratory tests were performed again using the same methods. Finally, the prevalence of confirmed positive TTI results among donated blood in Kurdistan blood center was compared before and after the establishment of program.

RESULTS

During the study, 4,434 new donors were screened for viral markers. A total of 41 new donors (0.92%, 95% CI, 0.007-0.13) had repeatedly reactive results and infection was confirmed in blood sample of 24 donors (0.54%, 95% CI, 0.003-0.008). Overall, 56% of new donors returned for blood donation. Prevalence of confirmed TTIs markers in collected blood units was 0.27% and 0 before and after implementing program, respectively.

CONCLUSIONS

This study indicated that Pre-donation screening can reduce the risk of TTI transmission by identifying infected donors at the pre-donation phase.

Review of blood donor deferral with emphasis on donor and patient safety

INTRODUCTION

Blood donor deferral is a part and parcel of the commitment of the blood transfusion services to assure the safety and health of the blood donor as well as the recipient. Periodic review of blood donor deferral is to incorporate or revoke deferral reasons based on the evidence generated in the process of review. Therefore, emphasis must be laid on preparing strategies to only judiciously defer blood donors, recruit and retain first time blood donors, which needs critical appraisal of the existing deferral policies, so that the evidence based changes can be done.

MATERIAL AND METHODS

A retrospective analysis of deferral in blood donors who presented at the blood donation centre of an institute of national importance over a span of nine years (2011-2019). Donors were screened as per the Drugs and Cosmetics Act 1940 and Rules 1945 given by the Ministry of Health and Family Welfare, Govt of India.

RESULTS

There were 1,37,935 donors attempts, out of which 20,167 (14.6%) donors were deferred from donating blood. Most of the deferred donors were male (88.5%), first time (86.1%) and temporarily deferred (87.6%). Almost comparable number of donors (49.1 % & 48.5%) were deferred for donor safety and patient safety reasons respectively. Overall the three most common reasons for deferral were low hemoglobin (21.6%), hypertension (11.4%) and history of jaundice (9%). In donor safety reasons, low hemoglobin (43.4%), hypertension (22.9%) and low blood pressure (4.5%), and in patient safety, a history of jaundice (18.6%), common cold (15.8%), and high-risk behavior (8.8%) emerged as the three most common reasons for deferral respectively.

CONCLUSION

Blood donor deferral is an essential quality indicator of the blood donor selection process. Initiatives like fortification of dietary ingredients with iron, optimizing protein in diet served in schools under mid-day meal program, screening for iron deficiency, hypertension and education about high-risk behavior in schools and colleges may have long term effects of promotion of better health.

The effect of motivational strategy on voluntary plasma donation, a field trial

BACKGROUND

Plasma protein therapies (PPTs) are a group of medicines extracted from human plasma through fractionation. The manufacture of adequate amounts of PPTs requires a large volume of human plasma. WHO emphasized that whole blood and blood component donations should be voluntary and non-remunerated. So, motivating people to donate plasma is crucial. In this study, we evaluated the impact of social media on motivating blood donors to donate plasma without any compensation and the moderating effects of blood donation history on plasma donation.

METHODS AND MATERIALS

we allocated blood donors (n = 501) to intervention and control groups randomly. Participants in the intervention group got educational and motivational messages through a WhatsApp channel. Then, we followed up all participants for six months and registered the information of the plasma donation during this period.

RESULT

In the intervention group, 6.8% had returned to donate plasma, while this was 2% in the control group (p = 0.016, OR:3.59, 95%CI:1.3-9.89). Among regular blood donors in the intervention group, 17.86% had returned to donate plasma but, no regular donor returned to donate plasma in the control group (p = 0.055). In addition, 10.8% of donors who had academic education in the intervention group returned to donate plasma, although this was 2.54% in the control group (P = 0.0485).

CONCLUSION

Our findings suggest that the educational interventions have more effects on academically educated donors to motivate them to donate plasma.

How to increase first-time donors' returns? The postdonation letter's content can make a difference

Background

Retention of first‐time donors is pivotal for blood collection centers. The present study built on research showing the importance of donor identity among regular donors and sought to compare the effectiveness of various communication strategies on return rate.

Study Design and Methods

Postal letters were sent to a large sample of first‐time whole blood donors (N = 1219) a few weeks following their first donation. Four versions of this letter were differently constructed in a way to boost the acquisition of donor identity (i.e., by including information about their ABO and Rh(D) blood group, emphasizing the salience of donor identity, offering a keyring with personalized information, or specifying the percentage of those sharing the same ABO and Rh(D) blood group). One version with no identity‐related information served as a control condition. Participants' subsequent blood donations were tracked for 5–22 months after receiving the letter.

Results

Survival analysis showed that the return rate was significantly higher among those who had received information about the percentage of the country's population with the same ABO and Rh(D) blood group (in comparison with the four other versions). There was no significant effect on the blood type rarity.

Conclusion

Blood collection centers could orient the strategy employed to communicate with first‐time donors to improve donors' retention. Arousing a sense of social identification with others with the same blood type may reveal a promising avenue.

Blood Donation in Lebanon: A Six-Year Retrospective Study of a Decentralized Fragmented Blood Management System

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.

Blood Donation Fear, Perceived Rewards, Self-Efficacy, and Intention to Return Among Whole Blood Donors in China: A Social Cognitive Perspective

With the increasing demand from aging population and seasonal blood shortage, recruiting and retaining blood donors has become an urgent issue for the blood collection centers in China. This study aims to understand intention to donate again from a social cognitive perspective among whole blood donors in China through investigating the association between the blood donation fear, perceived rewards, self-efficacy, and intention to return. A cross-sectional survey was conducted in six cities, which are geographically and socioeconomically distinct areas in Jiangsu, China. Respondents completed a self-administrated questionnaire interviewed by two well-trained medical students. A total of 191 blood donors were included in the current study. Descriptive analysis, correlation analysis, and a generalized linear regression model were used to explore the association between demographic characteristics, psychological factors, and intention to donate again. After controlling other covariates, donors with higher fear scores reported lower intention to return (p = 0.008). Association between self-efficacy and intention to return was statistically significant (p < 0.001), whereas the association between intrinsic rewards (p = 0.387), extrinsic rewards (p = 0.939), and intention to return were statistically insignificant. This study found that either intrinsic rewards or extrinsic rewards are not significantly associated with intention to donate again among whole blood donors in China, and fear is negatively associated with intention to donate again. Therefore, purposive strategies could be enacted beyond appeals to rewards and focus on the management of donors’ fear.

The Impact of COVID-19 Pandemic on Blood Transfusion Services: A Perspective from Health Professionals and Donors

Purpose

Since the emergence of the COVI9-19 pandemic, there has been concern about the availability and sufficiency of blood transfusions to meet patient needs. Also, the adequate and safe blood supply is a major issue to fulfill present demands. This study aims to determine the impact of the COVID-19 pandemic on the blood transfusion service and identify solutions to overcome this impact from the perspective of blood donors and healthcare professionals.

Methods

This study was conducted prospectively among Saudi Arabian blood donors and healthcare professionals between May 2020 and May 2021. A group of professional health care professionals and blood donors participated in this study to determine the impact of the COVID-19 pandemic on blood transfusion services and identify possible solutions to overcome the adverse effects on blood system activities.

Results

To understand the impact of pandemic COVID-19 on blood transfusion services in Saudi Arabia, we investigated population dynamics and statistical analysis from different age groups and health care professionals. A total of 424 blood donors and 372 healthcare professionals participated in this study. The suggested solution by the participants to overcome the blood shortage during pandemics was the organization of mobile blood drives at donors’ homes, work, and educational sites. Statically significant associations were found between blood donation during this pandemic and age (p=0.019) and marital status (p=0.001).

Conclusion

The findings of this study highlight the main problems of blood transfusion due to the onset of COVID-19. Hence, the data could be a source of improving blood transfusion and blood donation systems by healthcare centers and on an individual basis. Healthcare professionals use this public management system in hospitals to minimize the adverse effects of the pandemic.

Blood Donation and Monetary Incentives: A Meta-Analysis of Cost-Effectiveness

The effectiveness of monetary incentives to increase altruistic behavior is in dispute. Paying blood donors might be ineffective, as it could decrease altruistic motivations of voluntary donors (motivational crowding-out) or decrease blood quality (increase transmittable infectious disease risks). In a meta-analysis, including observational studies, natural experiments and field experiments, the cost-effectiveness of monetary incentives (cash payments and quasi-cash material rewards) for blood donation is estimated. The search strategy identified 17 studies as eligible. After screening for relevance and quality, 8 studies were retained and GRADE-rated for quality of evidence, offering 12 estimates of the marginal donation rate. The combined, random-effects estimate of the marginal donation rate of monetary incentives is 0,4 extra blood units collected per 1000 inhabitants per year per dollar incentive, but with large variation due to large heterogeneity of the studies (explained by different contexts and differences in perceived costs for donors). A higher estimate of 1,0 extra blood units per 1000 inhabitants per year per dollar incentive, is obtained with a restricted meta-analysis that only includes the most reliable and more homogeneous studies. With donor payments, it costs an additional $22 to $121 to increase the blood supply with one unit of whole blood, but this strongly varies with context and local conditions. The positive marginal donation rate of donor payments is inconsistent with a crowding-out effect (a reduction in total blood supply caused by a decrease in altruistic motivations when donors are paid), at least in the short-run. The available studies are not suitable to estimate possible long-term crowding-out effects, negative spillover effects (eg, a decrease in other prosocial behavior or altruistic norms) or transmittable infectious disease risks. Whether monetary incentives are the most cost-effective and ethical strategy to increase blood and plasma supply, remains an open question.

Analysis of blood donors' characteristics and deferrals related to COVID-19 in Iran

BACKGROUND

With the outbreak of the coronavirus disease in 2019, called COVID-19, Iranian Blood Transfusion Organization (IBTO) implemented the new deferrals. This study analyzed the COVID-19 deferrals of blood volunteers and compared the demographics, deferrals, and the donor status during the COVID-19 outbreak in 2019.

STUDY DESIGN AND METHODS

Data were collected from the integrated blood donor database between Feb-Apr 2019 and 2020. Deferral reasons of COVID-19 were categorized as: those who have symptoms or live with a symptomatic family member, have direct exposure with a confirmed case, have travelled from the outbreak affected areas, and have fully recovered from confirmed COVID-19. The z-test analysis was used, and 95 % confidence intervals were calculated to compare the sample proportions.

RESULTS

The blood donations dropped to 26.09 % in 2020. The percent change of first-time blood donors, female donors, and donors within the age group of 45-54 years old was significantly greater in 2020 than the same time frame in 2019 (p < 0.05). The results showed that 0.58 % of volunteers were deferred from blood donation to avoid transmission of SARS-CoV-2. The rate of COVID-19 deferrals in all types except travelling to affected areas has increased in the second 30-day of the study (p < 0.05).

CONCLUSION

The blood shortage that occurred during the COVID-19 outbreak was not due to increased deferral for COVID-19, but it was mostly due to a decrease in the number of volunteers who referred to BTCs.
