Attitudes towards biosample donation in andrology patients

Comparison of factors influencing the willingness to donate biospecimens among guardians of children with cancer and adult cancer patients

Background

This study examined and compared the attitudes and willingness of guardians of children with cancer and adult cancer patients toward donating biospecimens and clinical data for cancer research.

Methods

We conducted a cross‐sectional study among guardians of children with cancer (Guardian group) from Shanghai Children's Medical Center and adult cancer patients (Adult group) from Shanghai Ninth People's Hospital between February 1, 2019, and January 31, 2020. Participants’ demographic data, willingness, and motivations for biospecimen donation were collected and analyzed.

Results

Of 670 participants, 90.8% (318/350) in the Guardian group and 88.1% (282/320) in the Adult group completed the questionnaire. Most participants were willing to donate residual tissue samples (92.8% in the Guardian group vs. 79.4% in the Adult group, p^ψ = 0.032) and clinical data (94.0% vs. 72.3%, p^ψ < 0.001) for medical research. Logistic regression analysis indicated that only child status (odds ratio [OR] = 0.140, p = 0.02), history of blood donation (OR = 4.467, p = 0.019) in the Guardian group, education (OR = 0.387, p = 0.037), and history of blood donation (OR = 2.556, p = 0.016) in the Adult group were significantly associated with participants’ willingness to donate biospecimens. The primary motivation for donation was helping other patients with cancer (65.4% vs. 24.5%, p^ψ < 0.001). The major barriers to donation were the potential to cause physical discomfort (61.0% vs. 64.9%, p^ψ = 0.032).

Conclusions

Guardians of children with cancer were more willing to donate biospecimens than adult cancer patients in China. It is essential to promote awareness of biospecimens donation, especially in adult cancer patients.

Patients' Knowledge and Attitude Toward Biobanks in Eastern Morocco

Background: To integrate biobanks into the Moroccan health system and to promote biobanks-based research projects, it is necessary to explore the knowledge of patients, their attitudes toward biobanks, and the reasons that motivate them to participate in biobanks. Methods: Face-to-face interviews were conducted with patients, and data were analyzed using SPSS. Results: One thousand one hundred thirty-three questionnaires were completed. The mean age of patients was 47.74 years (SD 15.26 years). More women (69%) were involved in this survey. Of the respondents, 97% had never heard of the term "biobanks." Knowledge of biobanks varied significantly with respondents' education level. Overall, 80.7% of the participants (n = 914) expressed their willingness to participate in biobanking through donation of biospecimens associated with personnel and health data. Willingness to participate in biobanks was significantly associated with gender and age. We found that the main barriers to participation in biobanks were the lack of trust in biomedical research and concerns about privacy. When asked about the preferred type of consent, the majority of patients (75%) opted for a one-time consent. Conclusion: Despite the lack of knowledge of biobanks among patients in Eastern Morocco, the majority of them expressed willingness to participate in biobanking through donation of biospecimens. However, active participation depended upon a number of factors, notably, the trust in biomedical research and privacy. Therefore, more efforts are needed to increase awareness and promote wider participation in biobanking.

Parental attitudes and willingness to donate children's biospecimens for congenital heart disease research: a cross-sectional study in Shanghai, China

OBJECTIVES

To assess attitudes and willingness of parents of children with congenital heart disease (CHD) regarding donating biospecimens for future CHD research, and to identify factors associated with biospecimen donation.

DESIGN

Face-to-face cross-sectional survey data were analysed using logistic regression.

SETTING

Cardiothoracic Surgery Inpatient Department, Shanghai Children's Medical Centre.

PARTICIPANTS

Parents of children attending the cardiothoracic surgery inpatient department at Shanghai Children's Medical Center, 1 March-31 December 2016.

PRIMARY AND SECONDARY OUTCOME MEASURES

Willingness and motivation regarding donating children's biospecimens, and ethical and legal considerations concerning children's future willingness to donate.

RESULTS

Of 550 parents, 508 completed the questionnaire (response rate=92.4%). Overall, 69.1% (n=351) were willing to donate their children's biospecimens for medical research. Multivariate analysis indicated higher education level (college/graduate degree: OR 2.435, 95% CI 1.221 to 4.857, p=0.012; high school: OR 1.827, 95% CI 1.190 to 2.804, p=0.006) and children's hospitalisation history (OR 1.581; 95% CI 1.069 to 2.338, p=0.022) were positively associated with willingness to donate. The most common motivation for donation was potential benefit to other children with CHD (81.2%, n=285). The main barriers to donation were physical discomfort to their children (52.3%, n=54) and concerns about personal privacy (47.1%, n=48). Most parents (86.0%, n=302) wanted to be informed of research results using their children's donated biospecimens, and 34.8% (n=177) believed that children aged 10-18 years had the right to consent independently to research participation.

CONCLUSIONS

Nearly 70% of the parents in this study were willing to donate their children's biospecimens for future CHD research. Parents' education level and children's hospitalisation history influenced willingness to donate. Most parents wanted to receive the research results related to their children's biospecimens.

Attitudes and Perceptions of Cancer Patients Toward Biospecimen Donation for Cancer Research: A Cross-Sectional Survey Among Chinese Cancer Patients

BACKGROUND

High-quality biospecimen collection from consented patients is crucial for cancer research activities. Patients' attitudes and willingness toward specimen donation influence high-quality biospecimen collection for cancer research activities.

METHODS

We carried out a cross-sectional study among randomly selected patients from 11 cancer departments of Tianjin Medical University Cancer Institute and Hospital between August 2014 and August 2015. A total of 784 patients were included to complete a 30-item self-administered survey. We evaluated the patients' willingness to consider providing leftover samples and additional samples for cancer research purposes.

RESULTS

Among 784 patients, 683 (87.1%) and 653 (83.3%) were willing to donate leftover tissue and surplus blood after diagnosis, respectively. Six hundred thirty-one (80.5%) were favorably disposed to consider donating both tissue and blood samples for future cancer research. Female patients showed less willingness to donate biospecimens or related clinical data for research. First-hospitalized or older patients were less willing to provide leftover biospecimens or additional blood samples or even clinical data for research. By contrast, patients with a higher education level were more likely to donate leftover tissues after biopsy or surgery for research activities.

CONCLUSIONS

Most Chinese cancer patients were willing to consider donating blood and tissue samples for cancer research. Several factors, including age, gender, first hospitalization, and education level, can influence their willingness to donate biospecimens. We need to provide proper education to increase understanding of patients in biobanking activities.

IMPACT

This study provides novel empirical data on the likelihood of donating surplus and additional biospecimens and clinical health information among Chinese cancer patients.

Consent for the use of human biological samples for biomedical research: a mixed methods study exploring the UK public's preferences

OBJECTIVE

A mixed-methods study exploring the UK general public's views towards consent for the use of biosamples for biomedical research.

SETTING

Cross-sectional population-based focus groups followed by an online survey.

PARTICIPANTS

12 focus groups (81 participants) selectively sampled to reflect a range of demographic groups; 1110 survey responders recruited through a stratified sampling method with quotas set on sex, age, geographical location, socioeconomic group and ethnicity.

MAIN OUTCOME MEASURES

(1) Views on the importance of consent when donating residual biosamples for medical research; (2) preferences for opt-in or opt-out consent approaches and (3) preferences for different consent models.

RESULTS

Participants believed obtaining consent for use of residual biosamples was important as it was 'morally correct' to ask, and enabled people to make an active choice and retain control over their biosamples. Survey responders preferred opt-in consent (55%); the strongest predictor was being from a low socioeconomic group (OR 2.22, 95% CI 1.41 to 3.57, p=0.001) and having a religious affiliation (OR 1.36, 95% CI 1.01 to 1.81, p=0.04). Focus group participants had a slight preference for opt-out consent because by using this approach more biosamples would be available and facilitate research. Concerning preferred models of consent for research use of biosamples, survey responders preferred specific consent with recontact for each study for which their biosamples are eligible. Focus group participants preferred generic consent as it provided 'flexibility for researchers' and reduced the likelihood that biosamples would be wasted. The strongest predictor for preferring specific consent was preferring opt-in consent (OR 4.58, 95% CI 3.30 to 6.35, p=0.015) followed by non-'White' ethnicity (OR 2.94, 95% CI 1.23 to 7.14, p<0.001).

CONCLUSIONS

There is a preference among the UK public for ongoing choice and control over donated biosamples; however, increased knowledge and opportunity for discussion is associated with acceptance of less restrictive consent models for some people.

Public perspectives on biospecimen procurement: what biorepositories should consider

PURPOSE

Human biospecimens are central to biobanking efforts, yet how members of the public think about biobank procurement strategies is not well understood. This study aimed to explore public perspectives toward the procurement of residual clinical material versus "direct" procurement strategies such as the drawing of blood.

METHODS

Members of the public residing in and beyond the biobank catchment area of the University of Iowa Hospitals and Clinics were randomly selected to participate in focus groups and a telephone survey.

RESULTS

The majority of survey participants (75%, n=559) found both residual and direct procurement strategies equally workable. Small proportions preferred either residual (15%; n=117) or direct (5%; n=40) procurement. Focus group participants (n=48) could identify benefits to both procurement strategies, but raised concerns about possible donor inconvenience/discomfort and reduced biospecimen accrual in the case of direct procurement. Residual procurement raised concerns about lower-quality samples being procured without full donor awareness.

CONCLUSION

Biobanks should consider that members of the public in their research programs may be willing to make specimen donations regardless of whether a residual or direct procurement strategy is employed. Limiting patient discomfort and inconvenience may make direct procurement strategies more acceptable to some members of the public. Ensuring donor awareness through effective informed consent may allay public concerns about the indirectness of donating clinical biospecimens.
