Deterrents in recruitment of COVID-19 convalescent plasma donors: Experience from a hospital-based blood centre in India

Motivation to participate and attrition factors in a COVID-19 biobank: A qualitative study

BACKGROUND

The Biobanque québécoise de la COVID-19 (Quebec Biobank for COVID-19, or BQC19) is a provincial initiative that aims to manage the longitudinal collection, storage, and sharing of biological samples and clinical data related to COVID-19. During the study, BQC19 investigators reported a high loss-to-follow-up rate. The current study aimed to explore motivational and attrition factors from the perspective of BQC19 participants and health care and research professionals.

METHODS

This was an inductive exploratory qualitative study. Using a theoretical sampling approach, a sample of BQC19 participants and professionals were invited to participate via semi-structured interviews. Topics included motivations to participate; participants' fears, doubts, and barriers to participation; and professionals' experiences with biobanking during the COVID-19 pandemic.

RESULTS

Interviews were conducted with BQC19 participants (n = 23) and professionals (n = 17) from 8 clinical data collection sites. Motivations included the contribution to science and society in crisis, self-worth, and interactions with medical professionals. Reasons for attrition included logistical barriers, negative attitudes about public health measures or genomic studies, fear of clinical settings, and a desire to move on from COVID-19. Motivations and barriers seemed to evolve over time and with COVID-19 trends and surges. Certain situations were associated with attrition, such as when patients experienced indirect verbal consent during hospitalization. Barriers related to human and material resources and containment/prevention measures limited the ability of research teams to recruit and retain participants, especially in the ever-evolving context of crisis.

CONCLUSION

The pandemic setting impacted participation and attrition, either by influencing participants' motivations and barriers or by affecting research teams' ability to recruit and retain participants. Longitudinal and/or biobanking studies in a public health crisis setting should consider these factors to limit attrition.

An Exploratory Study of the Differences in Attitudes and Motives Regarding COVID-19 Plasma Donation

Background: Understanding the attitude and motives and differences between voluntary and replacement blood donation is the key to the sustainable availability of this precious resource. This study aimed to assess the attitude and motives for convalescent plasma (CP) donation in the recovered COVID-19 plasma donors and further understand the differences between voluntary and replacement donation.Materials and Methods: This prospective cross-sectional survey-based study was conducted among500 COVID-19 recovered blood donors who visited for CP donation at a tertiary care super-speciality centre in northern India. Data were collected using a structured questionnaire based on donor attitude, motives, and belief, which was validated by the experts of Psychiatry, Transfusion Medicine, and Epidemiology and was administered by the online medium.Results: The study’s findings depicted that voluntary plasma donors were previously regular blood donors (36.8%) compared to replacement plasma donors (26.4%). Almost all voluntary donors (99.5%) showed altruistic reasons to donate plasma and expressed that donating plasma is a good way to save a life, and it was more than for replacement plasma donors (p=0.004). The motives of most voluntary plasma donors were to contribute to society, and they believed that donating plasma is a good way, while it was not the case for most replacement plasma donors (p=0.02). Voluntary donors were more eagerly willing to donate plasma to help COVID sufferers (40.9%) when compared to replacement donors (33.2%) (p=0.037).Conclusion: Most voluntary plasma donors were regular whole blood donors and were keen to contribute to society. Convalescent plasma donation during this time of grief and loss was considered a moral responsibility by voluntary donors. The impact of media was more highly perceived in voluntary plasma donors when compared to replacement donors.

Analysis of responses of the health care workers recovered from COVID-19 on convalescent plasma donation by apheresis: A single-center survey study

Background

The COVID‐19 convalescent plasma (CCP) has been tried as a therapy in moderate COVID‐19 pneumonia. Donation of CCP requires motivation from recovered patients. This study evaluated the response of such recovered health care workers (HCWs) when they were motivated for CCP donation.

Methods

An interview‐based survey was carried out with recovered HCWs as study participants between August 2020 and November 2020. A qualified social worker explained the details of CCP donation over a mobile call; he clarified all their doubts and motivated them for the plasma donation. Their responses were recorded as “interested” or “not interested” followed by analysis.

Results

We tried to call 624 recovered HCWs, but could not reach 213, and the final group available for the study was 411 participants. Of these 411, 186 were deferred. Finally, we analyzed a total of 225 responses. Eventually, 105 out of 225 HCWs (47%) were interested; there were no significant differences in responses among males and females and between different age groups (<.001) and the “doctors” designation category (P = .01) had a maximum number of “interested” responses. In multivariate logistic regression, only the “interested” responses of the doctors were significantly higher after adjusting the confounding effect of the “graduate and above” educational qualification category.

Conclusion

This study found that nearly half of the eligible HCWs were interested in CCP donation. The educational qualification and designation among the recovered HCWs had an impact on CCP donation interest. The doctors were more interested in CCP donation compared to others.

Donor's Perspectives on Blood Donation During Covid-19 Pandemic

Covid-19 pandemic had affected transfusion services including recruitment of donors and blood donation camps activities. The blood donors may have concerns, confusion, and misleading rumours about blood donation during pandemic. People's priorities for blood donation may shift because of a dearth of necessities. It is important to identify factors which prevent or motivate blood donors during pandemic. This study was designed to understand blood donors' knowledge, attitudes, and perceptions during the Covid-19 pandemic. A descriptive cross-sectional study to assess donor’s knowledge, attitude, and perception regarding blood donation using self-administered 20 questions. The study duration was 4 months. A total 503 whole blood donors participated. The fear of infection and reduced blood donor motivation were observed to be the major deterrents of blood donation activity. Environment of blood donation area and travel to blood donation site were perceived two major sources of Covid-19 infection by participants. The top 3 motivational factor for blood donation were direct patient request to donate (30%), followed by family/ friends need and social media campaigns (26% each). Most donors (70.6%) were aware of importance of Covid-19 appropriate behaviour during current pandemic. The 67% donors felt that adequate Covid-19 preventive measures had been followed by the staff involved in blood collection. Based on the survey results, the inferences are that donors may harbour fear of infection and concerns for their safety, deterring blood donation. The direct appeal from a patient's relative to donate blood or a requirement in their family/friends and social media appeals emerge important factors to motivate donors. Travel facility arrangement may aide blood donation. Most of the donors are more than satisfied with the blood donation experience and are motivated to inform the transfusion services of any appearance of Covid-19 symptoms post donation. The donors were satisfied with the steps to reduce Covid-19 infection.

Deterrents in recruitment of COVID-19 convalescent plasma donors: Experience from a hospital-based blood centre in India

INTRODUCTION

Recruitment of Covid-19 convalescent plasma (CCP) donors may present as a challenge due to inexperience and differences in donor profile as compared to whole blood donation. Present study highlights the deterrents to recruiting CCP donors at a hospital based blood centre.

MATERIALS AND METHODS

Potential CCP donors were contacted individually by telephone and a group approach through camp organisers from May to July 2020. Recruitment challenges were noted and deferrals of these recruited donors during screening and medical examination was obtained and analysed.

RESULTS

Total 1165 potential CCP donors were contacted. Around 47% donors were lost due to challenges related to information storage and retrieval. Fear of health, family pressure, and fear of a new procedure were major reason (27.2%) for unwillingness to donate. The main reasons for deferral among potential donors were multiparity (38%) and being overage/underage (31.6%). Finally, 468 donors were recruited including 408 by individual approach and 60 by a group approach. From these absence of detectable COVID-19 antibodies were found in 15.4%. Few donors (9.0%) were deferred as they had not completed 28 days post recovery.

CONCLUSION

The process of CCP donor recruitment differs from that of whole blood donation and requires an individualised approach with involvement of clinicians in the initial phases of the pandemic. A group approach targeting specific organisations could be adopted for a successful CCP collection program. There is a need to relook into some aspects of donor selection such as consideration of multiparous female donors and overage/underage donors after reviewing scientific evidence.
