Attitudes and perceptions of patients towards methods of establishing a DNA biobank

Genetic tests as the strongest motivator of cooperation between participants and biobanks-Findings from cross-sectional study

Introduction

The development of the scientific potential linked with biobanking and research on human biological material is highly dependent on the willingness of potential donors to cooperate with entities that collect the material. For this reason, it is crucial to identify the circumstances and factors that may encourage potential participants to donate their biological material. In particular, knowledge of the motivational factors that can be modified by the persons managing a biobank may prove notably important for shaping the organizational and communication policy of the biobank and other scientific institutions.

Material and methods

The research was carried out on a group of 1,100 people over 18 years of age representing the adult population of Poland in 2021.

Results

More than half of the respondents declared their willingness to donate a blood sample for research purposes to a biobank (57.8%). The most often indicated incentives among the factors supporting the donation of biological material were offers of: obtaining the results of genetic tests predicting the risk of diseases (77.1%), blood tests (71.3%), the possibility of obtaining a small remuneration (64.6%) and the carrying out of genetic ancestry tests (60.4%).

Conclusion

Offering the possibility of performing additional diagnostic tests, especially genetic tests, may significantly increase the willingness of potential donors to cooperate with biobanks and other entities collecting human biological material for the purpose of scientific research. However, attention should also be paid to the challenges and risks linked with respecting the privacy and autonomy of research participants.

When Biobanks Meet Religion: Association Between Religiosity and Attitudes of Polish Medical Students Toward Biobanking of Human Biological Material for Research Purposes

While biobanking is expanding globally, the empirical evidence concerning the impact of religion on future healthcare professionals' awareness and willingness to donate biospecimens for biobank research is lacking. To understand how medical students' religious beliefs can fuel their questions regarding how biospecimens would be stored, cared for, and used, we conducted a survey among 1500 medical students at Poznań University of Medical Sciences. Our findings suggest that, while both religious and nonreligious students supported the idea of biobanking of human biological material and were willing to donate for research purposes, nonreligious students felt more positive toward biobanking, supported the idea of establishing biobanks in Poland more often, and were more eager to donate most types of tissues and to participate in biobank research. Religious beliefs were also associated with medical students' perception of benefits and risks resulting from biobanking, perceived trust toward various biobank institutions, and preferred type of consent.

Phenomewide Association Study of Health Outcomes Associated With the Genetic Correlates of 25 Hydroxyvitamin D Concentration and Vitamin D Binding Protein Concentration

While it is known that vitamin D deficiency is associated with adverse bone outcomes, it remains unclear whether low vitamin D status may increase the risk of a wider range of health outcomes. We had the opportunity to explore the association between common genetic variants associated with both 25 hydroxyvitamin D (25OHD) and the vitamin D binding protein (DBP, encoded by the GC gene) with a comprehensive range of health disorders and laboratory tests in a large academic medical center. We used summary statistics for 25OHD and DBP to generate polygenic scores (PGS) for 66,482 participants with primarily European ancestry and 13,285 participants with primarily African ancestry from the Vanderbilt University Medical Center Biobank (BioVU). We examined the predictive properties of PGS25OHD, and two scores related to DBP concentration with respect to 1322 health-related phenotypes and 315 laboratory-measured phenotypes from electronic health records. In those with European ancestry: (a) the PGS25OHD and PGSDBP scores, and individual SNPs rs4588 and rs7041 were associated with both 25OHD concentration and 1,25 dihydroxyvitamin D concentrations; (b) higher PGS25OHD was associated with decreased concentrations of triglycerides and cholesterol, and reduced risks of vitamin D deficiency, disorders of lipid metabolism, and diabetes. In general, the findings for the African ancestry group were consistent with findings from the European ancestry analyses. Our study confirms the utility of PGS and two key variants within the GC gene (rs4588 and rs7041) to predict the risk of vitamin D deficiency in clinical settings and highlights the shared biology between vitamin D-related genetic pathways a range of health outcomes.

Associations between the Willingness to Donate Samples to Biobanks and Selected Psychological Variables

Over the past few decades, there has been a dynamic development of biobanks collecting human biological material and data. Advances in biomedical research based on biobanks, however, are highly dependent on the successful enrolment and participation of human subjects. Therefore, it is crucial to recognise those factors affecting the willingness of individuals to participate in biomedical research. There are very few studies pointing to the role of trust, preferred values and specific psychological factors. The aim of our study was the analysis of the most significant relationships between selected moral and psychological variables (i.e., preferred values, types of trust and personality) and willingness to donate biological material to biobanks. The research was carried out on a Polish representative national sample of 1100 people over 18 years of age. Statistical methods with regression models were used during the analyses. The willingness to donate samples to a biobank was associated with different types of trust and specific values. Based on regression analysis, the most important factors related to the willingness to donate material to biobanks seemed to be (1) trust towards scientists and doctors and (2) selected preferred values such as knowledge, self-development and tradition. Other values or personality traits did not seem to be as important in this context. The obtained results can be useful in building the social responsibility of biobankers and scientists, issuing more appropriate opinions by research ethics committees and planning better communication strategies between participants and biobanks.

Pediatric biobanks and parents of disabled children associations opinions on establishing children repositories in developing countries

Pediatric biobanks are an indispensable resource for the research needed to bring advances in personalized medicine into pediatric medical care. It is unclear how or when these advances in medical care may reach children, but it is unlikely that research in adults will be adequate. We conducted the screening for a hypothetic problem in various European and American pediatric biobanks based on online surveys through e-mail distribution based on the Biobank Economic Modeling Tool (BEMT) questionnaire model. Participants in the survey had work experience in biobanking for at least 3 years or more. Contact information about the survey participants was confirmed on the social networks profiles (LinkedIn), as well as on generally available websites. First, we tried creating a model which can show the pediatric preclinical and basic clinical phase relationship and demonstrate how pediatric biobanking is linked to this process. Furthermore, we tried to look for new trends, and the final goal is to put the acquired knowledge into practice, so medical experts and patients could gain usable benefit from it. We concluded that leading positions must take into account ethical and legal aspects when considering the decision to include children in the biobank collection. However, communication with parents and children is essential. The biobank characteristics influence the biobank's motives to include children in the consent procedure. Moreover, the motives to include children influence how the children are involved in the consent procedure and the extent to which children are able to make voluntary decisions as part of the consent procedure.

Research participant understanding and engagement in an institutional, self-consent biobank model

The number of institutional and governmental biobanks and the target enrollment sizes of modern biobanks are increasing, affording more opportunities for the public to participate in biobanking efforts. In parallel with these expansions are pressures to increase the efficiency of obtaining informed consent using shorter consent forms that cover a broader scope of research and increasingly include provisions for return of research or clinical genetic test results to participants. Given these changes, how well these participants understand genetics, their level of understanding of what they are consenting to, and their wishes to engage longitudinally and receive biobank results are not well understood. We surveyed participants in a large, medical system-based biobank who had enrolled through a two-page, self-consent process about their baseline knowledge of genetics, understanding and recall of the consent process, wishes for future contact and engagement, and level of interest in receiving clinical genetic testing results. A total of 856 consented persons participated in the survey (67% women; 67% white). Participants' general reported genetics knowledge was relatively high (mean 11.60 of 15 questions answered correctly) as was recall of key elements from the two-page consent form. Overall participant enthusiasm for future contact by the biobank and for receiving clinical genetic testing results was high. The use of a two-page, self-consent process in a large, institutional biobank resulted in high levels of consent recall and enthusiasm for future ongoing engagement and receipt of genetic testing results by participants.

Control, trust and the sharing of health information: the limits of trust

Clinical information about patients is increasingly being stored in electronic form and has therefore become more easily shareable. Data are collected as part of clinical care but have multiple other potential uses in relation to health system planning, audit and research. The use of clinical information for these secondary uses is controversial, and the ability to safeguard personal and sensitive data under current practices is contested.In this study, we investigate the attitudes of a representative sample of the Danish population towards transfer of clinical data from their general practice for secondary use. We specifically study: (1) patients' trust in different types of healthcare professionals, (2) their interest in being asked about secondary use of data and (3) their willingness to dispense from a requirement of informed consent based on their trust in healthcare professionals.We find that adult Danes are positive towards research that use patient data, and they generally trust general practitioners, hospitals and researchers to treat their data confidentially.Nevertheless, they feel that they have a right to control the use of their data, only 7.3% disagreeing, and that the data belong to them, only 14.0% disagreeing. Answers to further questions about the relation between trust, information and consent show that although trust modifies the wish for information and consent, there is still a strong view that the patient should control the use of data. We find no differences between those who have frequent contact with the healthcare system and those who do not.

Patient Preferences for Use of Archived Biospecimens from Oncology Trials When Adequacy of Informed Consent Is Unclear

BACKGROUND

Oncology research increasingly involves biospecimen collection and data sharing. Ethical challenges emerge when researchers seek to use archived biospecimens for purposes that were not well defined in the original informed consent document (ICD). We sought to inform ongoing policy debates by assessing patient views on these issues.

MATERIALS AND METHODS

We administered a cross-sectional self-administered survey to patients with cancer at an academic medical center. Survey questions addressed attitudes toward cancer research, willingness to donate biospecimens, expectations regarding use of biospecimens, and preferences regarding specific ethical dilemmas.

RESULTS

Among 240 participants (response rate 69%), virtually all (94%) indicated willingness to donate tissue for research. Most participants (86%) expected that donated tissue would be used for any research deemed scientifically important, and virtually all (94%) expected that the privacy of their health information would be protected. Broad use of stored biospecimens and data sharing with other researchers increased willingness to donate tissue. For three scenarios in which specific consent for proposed biobank research was unclear within the ICD, a majority of patient's favored allowing the research to proceed: 76% to study a different cancer, 88% to study both inherited (germline) and tumor specific (somatic) mutations, and 70% to permit data sharing. A substantial minority believed that research using stored biospecimens should only proceed with specific consent.

CONCLUSION

When debates arise over appropriate use of archived biospecimens, the interests of the research participants in seeing productive use of their blood or tissue should be considered, in addition to addressing concerns about potential risks and lack of specific consent.

IMPLICATIONS FOR PRACTICE

This survey evaluated views of patients with cancer regarding the permissible use of stored biospecimens from cancer trials when modern scientific methods are not well described in the original informed consent document. The vast majority of patients support translational research and expect that any biospecimens they donate will be used to advance knowledge. When researchers, policy makers, and those charged with research oversight debate use of stored biospecimens, it is important to recognize that research participants have an interest in productive use of their blood, tissue, or data, in addition to considerations of risks and the adequacy of documented consent.

Willingness of women to participate in obstetrical and pediatric research involving biobanks

Use of biobanks for future genetic/genomic testing has increased. Biospecimens are increasingly being collected from infants/children; however, little is known about attitudes towards collection of biospecimens from postpartum women and their child. Using a hypothetical consent, this study investigated willingness to participate and attitudes, beliefs, and concerns related to consent materials requesting the biobanking genetic samples. A cross-sectional mixed methods design included women who reviewed a hypothetical consent related to biobanking genetic samples. Women were asked about their willingness to participate, followed by a focus group about biobanks and genetic/genomic testing. Post-focus group questionnaires assessed willingness to participate, the influence of study characteristics, and attitudes about genetic testing. Women (N = 37) were 29.0± 7.3 years of age (range 19-44); 51% had children and 28% were currently pregnant. A total of 46% were Hispanic (H), 38% were White non-Hispanic (WNH), and 16% were Native American (NA). Seventy-six percent (28/37) initially indicated that they would participate in the hypothetical study. Race and ethnicity impacted whether women would participate. Fewer NA women indicated that they would participate compared with H women and with WNH women (p < 0.02). Age, pregnancy status, having children, education level, insurance status, and income had no impact on participation decision and willingness to biobank specimens. NA and H women indicated that they were less likely than WNH women to agree to participate in a long-term biobank study. Given the importance of determining the genetic influence of health and disease, it is critical to attend to the questions and concerns of minority women regarding genetic studies.

On Sharing Intentions, and Personal and Interdependent Privacy Considerations for Genetic Data: A Vignette Study

Genetics and genetic data have been the subject of recent scholarly work, with significant attention paid towards understanding consent practices for the acquisition and usage of genetic data as well as genetic data security. Attitudes and perceptions concerning the trustworthiness of governmental institutions receiving test-taker data have been explored, with varied findings, but no robust models or deterministic relationships have been established that account for these differences. These results also do not explore in detail the perceptions regarding other types of organizations (e.g., private corporations). Further, considerations of privacy interdependence arising from blood relative relationships have been absent from the conversation regarding the sharing of genetic data. This paper reports the results from a factorial vignette survey study in which we investigate how variables of ethnicity, age, genetic markers, and association of data with the individual's name affect the likelihood of sharing data with different types of organizations. We also investigate elements of personal and interdependent privacy concerns. We document the significant role these factors have in the decision to share or not share genetic data. We support our findings with a series of regression analyses.

Public Attitudes toward Biobanking of Human Biological Material for Research Purposes: A Literature Review

Background: During the past few decades there has been a growing interest on the part of many governments in the creation of biobanks. Nevertheless, this would be impossible without participation of many donors who offer samples of their biological material for scientific research. Therefore, the aim of this paper is to provide an overview of the existing research on social attitudes towards biobanking. Material and Methods: A literature search was conducted in the database of MEDLINE (PubMed). 61 papers were included in the analysis. The retrieved articles were assessed using a thematic analysis. Results: Eight main themes were identified: (1) public knowledge about biobanks, (2) public views on biobanking, (3) willingness to donate, (4) donors’ motivations, (5) perceived benefits and risks of biobanking, (6) preferred type of consent, (7) trust toward biobanks, and (8) demographic characteristics of potential donors. Conclusions: Although the public lacks knowledge about biobanking, many individuals declare willingness to donate. Their will is influenced by: their knowledge about biobanking, the type of donated tissue, research purpose, concerns over the safety of the data, preferred type of consent, and trust towards biobanks.

Hopeful and Concerned: Public Input on Building a Trustworthy Medical Information Commons

A medical information commons (MIC) is a networked data environment utilized for research and clinical applications. At three deliberations across the U.S., we engaged 75 adults in two-day facilitated discussions on the ethical and social issues inherent to sharing data with an MIC. Deliberants made recommendations regarding opt-in consent, transparent data policies, public representation on MIC governing boards, and strict data security and privacy protection. Community engagement is critical to earning the public's trust.

Gender dynamics in the donation field: human tissue donation for research, therapy and feeding

This paper examines how gender dynamics shape human tissue donation for research and for human health. Drawing on research investigating the donation of different types of bodily tissues including blood, plasma, breastmilk, cord blood, foetal tissue and placentae we consider how and why women and men are viewed as different kinds of donors. We situate these donation practices within a broader understanding of gender difference to explain why any sociology of donation needs to take account of gender. In so doing we explore how tissue derived from the bodies of women acquires value in distinctive ways and for distinctive purposes and reasons. Within these gendered bioeconomies of donation, the supply and demand for tissue is structured by social understandings of maternity, parental responsibility, and risk, which in turn affect the experiences of donors.

Willingness to Participate and Associated Factors in a Zika Vaccine Trial in Indonesia: A Cross-Sectional Study

One of the crucial steps during trials for Zika and other vaccines is to recruit participants and to understand how participants' attitudes and sociodemographic characteristics affect willingness to participate (WTP). This study was conducted to assess WTP, its explanatory variables, and the impact of financial compensation on WTP in Indonesia. A health facility-based cross-sectional study was conducted in eleven regencies in the Aceh and West Sumatra provinces of Indonesia. Participants were recruited via a convenience sampling method and were interviewed. The associations between explanatory variables and WTP were assessed using a two-step logistic regression analysis. A total of 1,102 parents were approached, and of these 956 (86.8%) completed the interview and were included in analysis. Of those, 144 (15.1%) were willing to participate in a Zika vaccine trial without a financial compensation. In the multivariate analysis, WTP was tied to an age of more than 50 years old, compared to 20⁻29 years (odds ratio (OR): 5.0; 95% confidence interval (CI): 2.37⁻10.53), to being female (OR: 2.20; 95% CI: 1.11⁻4.37), and to having heard about Zika (OR: 2.41; 95% CI: 1.59⁻3.65). Participants' WTP increased gradually with higher financial compensation. The rate of WTP increased to 62.3% at the highest offer (US$ 350.4), and those who were still unwilling to participate (37.7%) had a poorer attitude towards childhood vaccination. This study highlights that pre-existing knowledge about Zika and attitudes towards childhood vaccination are important in determining community members being willing to participate in a vaccine trial. Financial incentives are still an important factor to enhance participant recruitment during a vaccine trial.

The Public's Awareness of and Attitude Toward Research Biobanks - A Regional German Survey

Background: Biobanks have become an increasingly important means of biomedical research and innovation. However, they entail a variety of ethical, social and legal challenges, which need to be publicly discussed and managed collectively. A certain level of public awareness of biobank research is an important prerequisite for the public to form an opinion on the issue at hand and to be willing to participate in public engagement activities. For many countries, including Germany, recent information on the public's awareness of and attitude toward biobanks is scarce. Methods: Therefore, by means of a postal survey in a German urban region, this study updates data from the 2010 Eurobarometer by analyzing (1) the public's awareness of biobanks, (2) their general attitude toward biobanks, and (3) their hypothetical willingness to donate their own biological samples and personal or medical data. Results: Overall, 204 (20.4%) of 998 delivered questionnaires were returned. The majority of survey respondents stated a positive attitude toward medical research (95.5%) and - to a somewhat lower degree - toward genetic research (61.3%). Attitudes toward biobanks were mixed but positive for the majority of respondents: in a question about their spontaneous assessment of biobanks as a means for medical research, 77% showed positive attitudes toward biobanks (36.6% "definitely" and 40.5% "somewhat positive"). This finding is also reflected in a high proportion of individuals willing to participate in biobank research: 70.4% of respondents would be willing to donate biomaterial to a biobank during a hypothetical stay in hospital. In spite of the high overall support respondents show for biobanks (e.g., positive general attitude and willingness to participate), only about one third (30.8%) had previously heard of biobanks. Discussion and Conclusion: The comparison of survey results with prior data from the 2010 Eurobarometer indicates that public awareness of biobanks remains low. A higher level of biobank awareness can be assumed to be one prerequisite for public engagement in future decisions on biobank governance. We therefore argue that to increase public awareness of biobanks and to enable public involvement in biobank governance, publicly available and understandable information must be provided and disseminated.

When Patient Engagement and Research Ethics Collide: Lessons from a Dementia Forum

The importance of patient engagement in research has been gaining recognition since the turn of the 21st century. However, little is known about the perspectives of people with dementia on the process of discovery. To fill this gap and to inform priorities in patient engagement in the context of dementia research, the Clinic for Alzheimer Disease and Related Disorders at the University of British Columbia hosted an interactive session for members of the patient community and of the general public to share their views on various ethical aspects of the research process. Results from the session indicate that several current research ethics policies and norms in dementia research are not in line with participants' preferences. Here we discuss the importance of bridging the gap between researchers and patients and call for reforms in current standards of dementia research.

Patient and community attitudes toward perioperative biobanking and genomic research

We surveyed hospital patients and clinicians to ascertain their attitudes to the establishment of a perioperative biobank for future genomics research, and whether the requirements for an opt-out approach to consent can be met. We enrolled hospital patients (n=187), patient spouse/family members (n=64), ethics committee members (n=14), and clinical staff (doctors and nurses [n=67]), and unspecified community members (n=10). They were asked to rate and describe their views on medical research and biobanking, the need for individual consent, and the importance of confidentiality. Of 406 survey forms distributed, 342 (84%) were returned. Nearly all participants (98%) indicated that a perioperative biobank is important, 93% were comfortable with de-identified genetic research, and 90% indicated that the hospital should be able to use leftover blood for medical research, provided the research has been approved by an ethics committee and personally identifying information has been removed. Participants were more likely to support biobanking if it used de-identified samples, and if, for this reason, their consent was not sought. Participants with chronic medical and surgical conditions were significantly more supportive and comfortable with genetic research, as were most in the hospital community. Most hospital patients, community members and clinicians are supportive of the development of a perioperative biobank used for genomic research. This supports the adoption of an opt-out approach to consent model.

The role of biobanks in elucidating prevalent genetic diseases in Saudi Arabia

Biobanking entails large-scale collection of human biological specimens that are linked to the donors' health and personal information, and has several applications in clinical research. Human biological specimens, such as blood, urine and tissue, have become immensely important to medical research: they offer a valuable source of genetic material that researchers can use to identify disease-associated genetic variation and to determine interactions between genes and environmental factors. Identification of genetic contributions to disease can lead to the development of new diagnostic tests and targeted treatments. Over the last decade, both common diseases and rare genetic disorders have been reported in Saudi Arabia. The need to generate extensive genetic data on these diseases has led to the establishment of several Saudi Arabian biobanks. Fortunately, these vital efforts have the support of the Saudi Government and researchers. However, the success of any biobank also requires public support and the willingness of the population to donate their biological material along with information on their medical records. Thus, the Saudi public needs to be informed of the benefits of maintaining biobanks, their participation needs to be encouraged through donation of biological material, and any public concerns regarding the confidential treatment of medical data need to be addressed. This article reviews the most common genetic diseases identified in the Saudi population, it describes biobanks and it examines how biobanks can support biomedical research in the area. Moreover, this article proposes measures that might help to increase public awareness of biobanks and the preparedness of the Saudi Arabian population to donate biological material.

Community Willingness to Participate in a Dengue Study in Aceh Province, Indonesia

BACKGROUND

Dengue virus infection is the most rapidly spreading vector-borne disease in the world. Essential research on dengue virus transmission and its prevention requires community participation. Therefore, it is crucial to understand the factors that are associated with the willingness of communities in high prevalence areas to participate in dengue research. The aim of this study was to explore factors associated with the willingness of healthy community members in Aceh province, Indonesia, to participate in dengue research that would require phlebotomy.

METHODOLOGY/PRINCIPAL FINDINGS

A community-based cross-sectional study was carried out in nine regencies and municipalities of Aceh from November 2014 to March 2015. Interviews using a set of validated questionnaires were conducted to collect data on demography, history of dengue infection, socioeconomic status, and knowledge, attitude and practice regarding dengue fever. Two-step logistic regression and Spearman's rank correlation (rs) analysis were used to assess the influence of independent variables on dependent variables. Among 535 participants, less than 20% had a good willingness to participate in the dengue study. The factors associated with good willingness to participate were being female, working as a civil servant, private employee or entrepreneur, having a high socioeconomic status and good knowledge, attitude and practice regarding dengue. Good knowledge and attitude regarding dengue were positive independent predictors of willingness to participate (OR: 2.30 [95% CI: 1.36-3.90] and 3.73 [95% CI: 2.24-6.21], respectively).

CONCLUSION/SIGNIFICANCE

The willingness to participate in dengue research is very low among community members in Aceh, and the two most important associated factors are knowledge and attitude regarding dengue. To increase participation rate, efforts to improve the knowledge and attitude of community members regarding dengue fever and dengue-related research is required before such studies are launched.

What Potential Donors in Research Biobanking Want to Know: A Large Population Study of the Italian Twin Registry

Donation of human tissues for research and ELSI (ethical, legal, and social issues) of biobanking are increasingly debated issues. While several studies have highlighted patients' concerns, little is known about opinions and preferences of healthy potential donors. Further investigations in this respect may allow communication procedures tailored to participants' needs. Based on the Italian Twin Registry, a cross-sectional survey was conducted among twins who had not yet donated biological samples for research. The objective was to assess the importance these potential donors attributed to specific procedures and pieces of communication related to research biobanking. A self-administered questionnaire was constructed and validated. Items were as follows: potential agreement on use of biological samples for research; knowledge of biobanks; and importance given to privacy protection and to communication of general and individual tests results, study objectives, type and amount of participant involvement, location and duration of sample storage, and benefits and potential risks. Multivariate analysis was performed to estimate the association of these items with sociodemographic factors as well as with perceived health status and chronic or long-term diseases. The questionnaire was mailed to 4894 twins aged 18-65 (response rate 34%). One-third of subjects already knew about biobanks, 52% had some knowledge, and 20% were uninformed. A majority expressed unconditional agreement to sample use for research. Only 6% of respondents considered privacy protection not important in research biobanking. Knowledge of biobanks predicted attention to most of the issues. Higher education was associated with more frequent concern about type and amount of involvement, but less frequent concern about place and time of storage, and presence of benefits. Women were more attentive to research biobanking. This study supports the need of procedures tailored on different donors' concerns and highlights the social value of population biobanks. Furthermore, the results call for greater efforts in the promotion of research biobanking.

Attitudes and willingness to donate biological samples for research among potential donors in the Italian Twin Register

Most ethical and social research is focused on disease-oriented biobanks, while healthy donors' motivation toward population biobanking is scarcely explored. We investigated willingness to donate biological samples for research and attitudes toward donation by a mail survey among 4,894 twins enrolled in the population-based Italian Twin Register. We compared responses in different socio-demographic categories and estimated, by the twin design, environmental and genetic components of this attitude. More than 80% of respondents expressed willingness to donate. A prevailing collaborative attitude to donation emerged. Attitude was mainly influenced by individual social and cultural factors. Education was important in shaping motivation and willingness to donate. Future surveys of the general population are desirable to continue investigating attitude toward donation and concerns about biobanking.

Factors Influencing Dental Patient Participation in Biobanking and Biomedical Research

OBJECTIVES

To study the willingness of dental patients to donate biospecimens for research purpose and to examine factors that may influence such a decision.

MATERIALS AND METHODS

A face-to-face interview was conducted using a pretested structured survey instrument on 408 adult dental patients attending a university hospital for dental care. Descriptive statistics were generated, and the x03C7;2 test was used to examine differences between groups. p values ≤0.5 were considered statistically significant.

RESULTS

Of the 408 participants, only 71 (17.4%) had heard of the terms biobanking/biospecimens, but 293 (71.9%) approved of the idea of using biospecimens for biomedical research, and 228 (55.9%) were willing to donate biospecimens and give personal information for research purposes. In participants who were unwilling to participate in biobanking, fear of information leakage was the most frequently reported reason, while in participants who were willing to donate biospecimens, the potential to provide more effective and less costly treatments was the most frequently reported reason. The preferences of the 228 participants who were willing to donate biospecimens were as follows: give a sample of removed oral tissues including extracted teeth (n = 105, 46.1%), donate a blood sample (n = 52, 23%), donate a sample of saliva (n = 43, 18.6%), and give a urine sample (n = 28, 12.3%).

CONCLUSION

Dental patients had a generally positive attitude towards biomedical research and biobanking. The most preferred types of biospecimens to donate in a dental setting were removed tissues, including extracted teeth and blood samples.

A systematic literature review of individuals' perspectives on broad consent and data sharing in the United States

PURPOSE

In 2011, an Advanced Notice of Proposed Rulemaking proposed that de-identified human data and specimens be included in biobanks only if patients provide consent. The National Institutes of Health Genomic Data Sharing policy went into effect in 2015, requiring broad consent from almost all research participants.

METHODS

We conducted a systematic literature review of attitudes toward biobanking, broad consent, and data sharing. Bibliographic databases included MEDLINE, Web of Science, EthxWeb, and GenETHX. Study screening was conducted using DistillerSR.

RESULTS

The final 48 studies included surveys (n = 23), focus groups (n = 8), mixed methods (n = 14), interviews (n = 1), and consent form analyses (n = 2). Study quality was characterized as good (n = 19), fair (n = 27), and poor (n = 2). Although many participants objected, broad consent was often preferred over tiered or study-specific consent, particularly when broad consent was the only option, samples were de-identified, logistics of biobanks were communicated, and privacy was addressed. Willingness for data to be shared was high, but it was lower among individuals from under-represented minorities, individuals with privacy and confidentiality concerns, and when pharmaceutical companies had access to data.

CONCLUSIONS

Additional research is needed to understand factors affecting willingness to give broad consent for biobank research and data sharing in order to address concerns to enhance acceptability.Genet Med 18 7, 663-671.

Are Patients With Cancer Less Willing to Share Their Health Information? Privacy, Sensitivity, and Social Purpose

PURPOSE

Growing use of electronic health information increases opportunities to build population cancer databases for research and care delivery. Understanding patient views on reuse of health information is essential to shape privacy policies and build trust in these initiatives.

METHODS

We randomly assigned nationally representative participants (N = 3,336) with and without prior cancer to six of 18 scenarios describing different uses of electronic health information. The scenarios varied the user, use, and sensitivity of the information. Participants rated each scenario on a scale of 1 to 10 assessing their willingness to share their electronic health information. We used conjoint analysis to measure the relative importance of each attribute (ie, use, user, and sensitivity).

RESULTS

Participants with and without a prior diagnosis of cancer had a similar willingness to share health information (0.27; P = .42). Both cancer and noncancer participants rated the purpose of information use as the most important factor (importance weights, 67.1% and 45.6%, respectively). For cancer participants, the sensitivity of the information was more important (importance weights, 29.8% v 1.2%). However, cancer participants were more willing to share their health information when the information included more sensitive genetic information (0.48; P = .015). Cancer and noncancer respondents rated uses and users similarly.

CONCLUSION

The information sharing preferences of participants with and without a prior diagnosis of cancer were driven mainly by the purpose of information reuse. Although conventional thinking suggests patients with cancer might be less willing to share their health information, we found participants with cancer were more willing to share their inherited genetic information.

Privacy in the Genomic Era

Genome sequencing technology has advanced at a rapid pace and it is now possible to generate highly-detailed genotypes inexpensively. The collection and analysis of such data has the potential to support various applications, including personalized medical services. While the benefits of the genomics revolution are trumpeted by the biomedical community, the increased availability of such data has major implications for personal privacy; notably because the genome has certain essential features, which include (but are not limited to) (i) an association with traits and certain diseases, (ii) identification capability (e.g., forensics), and (iii) revelation of family relationships. Moreover, direct-to-consumer DNA testing increases the likelihood that genome data will be made available in less regulated environments, such as the Internet and for-profit companies. The problem of genome data privacy thus resides at the crossroads of computer science, medicine, and public policy. While the computer scientists have addressed data privacy for various data types, there has been less attention dedicated to genomic data. Thus, the goal of this paper is to provide a systematization of knowledge for the computer science community. In doing so, we address some of the (sometimes erroneous) beliefs of this field and we report on a survey we conducted about genome data privacy with biomedical specialists. Then, after characterizing the genome privacy problem, we review the state-of-the-art regarding privacy attacks on genomic data and strategies for mitigating such attacks, as well as contextualizing these attacks from the perspective of medicine and public policy. This paper concludes with an enumeration of the challenges for genome data privacy and presents a framework to systematize the analysis of threats and the design of countermeasures as the field moves forward.

Establishment and management of a lung cancer biobank in Eastern China

Background

The prevalence of lung cancer, a highly complex neoplasm, increases annually. Thus, a lung cancer biobank, which stores lung cancer tissue and blood matched according to standard methods, is needed to advance lung cancer research and develop promising therapies.

Methods

To accomplish this aim, we implemented standardized procedures for tissue samples and patient information acquired from consenting donors. The banked tissue includes blood, pleural effusions, and surgical resection samples. An independent information management system was used to match samples and collect data, including clinical cancer manifestation, laboratory tests, and de-identified data about cancer patients.

Results

From 2009 to 2013, more than 2000 lung cancer cases were collected. At this time, we have more than 10 000 biological samples stored in our biobank. DNA, ribonucleic acid (RNA), and protein quality were confirmed to be appropriate for clinical and basic research.

Conclusion

Our standardized, large-scale lung cancer biobank offers high quality cancer research samples for China and the world.

Development and validation of the biobanking attitudes and knowledge survey (BANKS)

BACKGROUND

No validated multiscale instruments exist that measure community members' views on biobanking and biospecimen donation. This study describes the development and psychometric properties of the English-language BANKS (Biobanking Attitudes and Knowledge Survey).

METHODS

The BANKS was created by item generation through review of scientific literature, focus groups with community members, and input from a community advisory board. Items were refined through cognitive interviews. Content validity was assessed through an expert panel review. Psychometric properties of the BANKS were assessed in a sample of 85 community members.

RESULTS

The final BANKS includes three scales: attitudes, knowledge, and self-efficacy; as well as three single items, which evaluated receptivity and intention to donate a biospecimen for research. Cronbach α coefficients for two scales that use Likert response format indicated high internal consistency (attitudes: α, 0.88; self-efficacy: α, 0.95). Content validity indices were moderate, ranging from 0.69 to 0.89. Intention to donate blood and intention to donate urine were positively correlated with attitudes, knowledge, self-efficacy, and receptivity to learning more about biobanking (P values range from 0.029 to <0.001).

CONCLUSIONS

The final BANKS shows evidence of satisfactory reliability and validity, is easy to administer, and is a promising tool to inform biospecimen research. Additional studies should be conducted with larger samples considering biospecimen donation to further assess the reliability and validity of the instrument.

IMPACT

A valid and reliable instrument measuring community members' views about biobanking may help researchers evaluate relevant communication interventions to enhance understanding, intention, and actual biospecimen donation. A Spanish-language BANKS is under development.

Impact of a biospecimen collection seminar on willingness to donate biospecimens among Chinese Americans: results from a randomized, controlled community-based trial

BACKGROUND

Biospecimen collection from diverse populations can advance cancer disparities research, but is currently underrepresented.

METHODS

We partnered with a community-based clinic serving Cantonese-speaking Chinese Americans to develop and revise an educational seminar on biospecimen collection. Through a randomized controlled trial (n = 395), the intervention seminar was compared with a control seminar (cancer prevention) on change in willingness to donate biospecimens.

RESULTS

At baseline, many were willing to donate a biospecimen (saliva, urine, hair, toenails, blood, unused cancerous tissue) whether healthy or hypothetically had cancer. Also, many would donate because future generations would benefit, and few had concerns about donation. In logistic regression analyses, there was an intervention effect for willingness to donate: urine if had cancer [OR, 2.2; 95% confidence interval (CI), 1.3-3.7], toenails if healthy (OR, 2.1; 95% CI, 1.4-3.2) or had cancer (OR, 2.3; 95% CI, 2.0-2.7), hair if healthy (OR, 1.8; 95% CI, 1.3-2.5) or had cancer (OR, 2.8; 95% CI, 1.9-4.0), and unused cancerous tissue (OR, 1.8; 95% CI, 1.2-2.9). There was also an intervention effect for donating because future generations would benefit (OR, 2.0; 95% CI, 1.4-3.0), and this attitude was a strong independent predictor for willingness to donate all biospecimens, whether healthy or had cancer (OR, 2.9-4.2).

CONCLUSION

Cantonese-speaking Chinese American participants of an educational seminar on biospecimen collection showed greater increases in willingness to donate biospecimens and donating for the benefit of future generations, than participants who attended a control seminar.

IMPACT

Donating for the benefit of future generations is a theme that should be incorporated in messages that encourage biospecimen donation for Chinese Americans.

Biobanks and electronic medical records: enabling cost-effective research

The use of electronic medical record data linked to biological specimens in health care settings is expected to enable cost-effective and rapid genomic analyses. Here, we present a model that highlights potential advantages for genomic discovery and describe the operational infrastructure that facilitated multiple simultaneous discovery efforts.

Cancer patient perceptions about biobanking and preferred timing of consent

Little is known about how cancer patients feel about donating their tissue, especially in a multiethnic population. Structured interviews were conducted with 30 patients recently diagnosed with cancer, referred to the study by six cancer surgeons and oncologists and by other patients in the study. The participants reported a variety of cancers, and the sample reflected the racial distribution of Hawai`i, including Caucasians (23%), Native Hawaiians and Pacific Islanders (27%), Asians (37%), Hispanics (7%), Native Americans (3%), and African Americans (3%). The interview questions and analysis were guided by the Framework Approach, with interview questions based on pre-set aims. Findings suggest that most cancer patients would donate cancer tissue to science, especially if informed that doing so could help researchers find causes of and cures for cancer. Patients varied on when in their cancer journey they would be most receptive to being asked for a donation, however two-thirds thought they would be more receptive if approached after surgery. Only three of the 30 patients said they would want to be re-consented each time their tissue is requested for research. They identified their physician as the preferred messenger regarding tissue donation. No obvious differences were seen by race. Findings confirm those of other researchers who have reported broad support for biobank participation if informed consent and confidentiality could be assured. Given that the physician was seen as the key messenger about biobanking, more education is needed around cancer tissue collection for physicians, as well as for cancer patients.

Promoting healthy dietary behaviour through personalised nutrition: technology push or technology pull?

The notion of educating the public through generic healthy eating messages has pervaded dietary health promotion efforts over the years and continues to do so through various media, despite little evidence for any enduring impact upon eating behaviour. There is growing evidence, however, that tailored interventions such as those that could be delivered online can be effective in bringing about healthy dietary behaviour change. The present paper brings together evidence from qualitative and quantitative studies that have considered the public perspective of genomics, nutrigenomics and personalised nutrition, including those conducted as part of the EU-funded Food4Me project. Such studies have consistently indicated that although the public hold positive views about nutrigenomics and personalised nutrition, they have reservations about the service providers' ability to ensure the secure handling of health data. Technological innovation has driven the concept of personalised nutrition forward and now a further technological leap is required to ensure the privacy of online service delivery systems and to protect data gathered in the process of designing personalised nutrition therapies.

Factors associated with willingness to participate in biospecimen research among Chinese Americans

A paucity of information exists on the recruitment of Asian Americans for biospecimen research. Although studies show that Chinese Americans are at high risk for hepatitis B virus (HBV) infection, little is known about their willingness to participate in HBV-related biospecimen research and how knowledge, attitudes, and cultural factors impact their willingness to participate. The study was guided by Community-Based Participatory Research principles. Data were derived from an assessment study on HBV-related biospecimen research participation among Chinese Americans in the Philadelphia region. The assessment was conducted with 415 Chinese Americans recruited from eight Chinese community-based organizations. Cultural beliefs, knowledge, and attitudes toward biospecimen research were examined for associations with their willingness to participate in biospecimen banking research. Overall, 192 (46.3%) of 415 participants who completed the assessment indicated they were willing to participate if they were invited to donate blood to be frozen and stored for future HBV biospecimen studies. Cultural variables significant in bivariate analysis included collectivism, knowledge about biospecimen research, and Yin-Yang beliefs. Fatalism and individualism were not associated with participation willingness. In multivariate analysis, age, health care attitudes, and trust were significantly associated with willingness to participate in biospecimen banking research. Asian American communities have little knowledge of biospecimen banking and will benefit from educational campaigns that emphasize collective benefits and attitudes towards and trust in the health care system. Understanding cultural factors is important for improving Chinese Americans' knowledge, awareness, and intentions of participation in biospecimen research. Similar efforts need to be undertaken to develop culturally appropriate educational intervention programs to increase participation in biospecimen research among other Asian American groups.

Public preferences about secondary uses of electronic health information

IMPORTANCE

As health information technology grows, secondary uses of personal health information offer promise in advancing research, public health, and health care. Public perceptions about sharing personal health data are important for establishing and evaluating ethical and regulatory structures to oversee the use of these data.

OBJECTIVE

To measure patient preferences about sharing their electronic health information for secondary purposes (other than their own health care).

DESIGN, SETTING, AND PARTICIPANTS

In this conjoint analysis study, we surveyed 3336 adults (568 Hispanic, 500 non-Hispanic African American, and 2268 non-Hispanic white); participants were randomized to 6 of 18 scenarios describing secondary uses of electronic health information, constructed with 3 attributes: uses (research, quality improvement, or commercial marketing), users (university hospitals, commercial enterprises, or public health departments), and data sensitivity (whether it included genetic information about their own cancer risk). This design enabled participants to reveal their preferences for secondary uses of their personal health information.

MAIN OUTCOMES AND MEASURES

Participants responded to each conjoint scenario by rating their willingness to share their electronic personal health information on a 1 to 10 scale (1 represents low willingness; 10, high willingness). Conjoint analysis yields importance weights reflecting the contribution of a dimension (use, user, or sensitivity) to willingness to share personal health information.

RESULTS

The use of data was a more important factor in the conjoint analysis (importance weight, 64.3%) than the user (importance weight, 32.6%) and data sensitivity (importance weight, 3.1%). In unadjusted linear regression models, marketing uses (β = -1.55), quality improvement uses (β = -0.51), drug company users (β = -0.80), and public health department users (β = -0.52) were associated with less willingness to share health information than research uses and university hospital users (all P < .001). Hispanics and African Americans differentiated less than whites between uses.

CONCLUSIONS AND RELEVANCE

Participants cared most about the specific purpose for using their health information, although differences were smaller among racial and ethnic minorities. The user of the information was of secondary importance, and the sensitivity was not a significant factor. These preferences should be considered in policies governing secondary uses of health information.

Ethical and practical challenges to studying patients who opt out of large-scale biorepository research

Large-scale biorepositories that couple biologic specimens with electronic health records containing documentation of phenotypic expression can accelerate scientific research and discovery. However, differences between those subjects who participate in biorepository-based research and the population from which they are drawn may influence research validity. While an opt-out approach to biorepository-based research enhances inclusiveness, empirical research evaluating voluntariness, risk, and the feasibility of an opt-out approach is sparse, and factors influencing patients' decisions to opt out are understudied. Determining why patients choose to opt out may help to improve voluntariness, however there may be ethical and logistical challenges to studying those who opt out. In this perspective paper, the authors explore what is known about research based on the opt-out model, describe a large-scale biorepository that leverages the opt-out model, and review specific ethical and logistical challenges to bridging the research gaps that remain.

Thematic analysis of cardiac care patients' explanations for declining contribution to a genomic research-based biobank

BACKGROUND

Health care delivery systems increasingly ask patients to contribute biological samples for future genomic-based health research during critical care admissions, as the result of genome-based research requirements of unprecedented large sample sizes. Few reports describe patients' perceptions and responses to actual biobanking approaches in clinical settings. A qualitative study was conducted to explore 568 cardiac care patients' explanations of why they declined to contribute their samples to a future genomic research biobank.

OBJECTIVES

To (1) identify themes emerging from explanations for declining contribution to the research biobanking initiative and (2) determine how the content informs the stewardship conceptual framework that addresses evidence-based clinical ethics practices in genomic and genetic research biobanking.

METHODS

This qualitative study used an analytic method that combines inductive and deductive approaches to identify themes in patients' explanations for declining to contribute to a research biobank initiative. The hybrid design has relevance to health services research that seeks to develop taxonomy, themes, and theory.

RESULTS

Inductive approaches showed that themes of intrusion and autonomy dominated explanations. Deductive approaches affirmed previously proposed elements of a stewardship conceptual framework that addresses ethics in biobanking.

CONCLUSION

Research in understanding patients' perceptions can guide nursing and biobank practices in developing best practices.

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.

Inclusion of pediatric samples in an opt-out biorepository linking DNA to de-identified medical records: pediatric BioVU

The Vanderbilt DNA repository, BioVU, links DNA from leftover clinical blood samples to de-identified electronic medical records (EMRs). After initiating adult sample collection, pediatric extension required consideration of ethical concerns specific to pediatrics and implementation of specialized DNA extraction methods. In the first year of pediatric sample collection, more than 11,000 samples from individuals younger than 18 years were included. We compared data from the pediatric BioVU cohort with those from the overall Vanderbilt University Medical Center pediatric population and found similar demographic characteristics; however, the BioVU cohort had higher rates of select diseases, medication exposures, and laboratory testing, demonstrating enriched representation of severe or chronic disease. The fact that the sample accumulation is not balanced may accelerate research in some cohorts while limiting the study of relatively benign conditions and the accrual of unaffected and unbiased control samples. BioVU represents a feasible model for pediatric DNA biobanking but involves both ethical and practical considerations specific to the pediatric population.

Factors influencing participation in a population-based biorepository for childhood heart disease

BACKGROUND

Consenting minors for genetics research and biobanking involves ethical and social challenges. We examined factors influencing participation rates in a population-based biorepository for childhood heart disease.

METHODS

Individuals were prospectively enrolled across 7 centers in Ontario by using a standardized consent form. Individuals were approached for consent for the donation of blood/saliva (DNA), tissue, and skin from the affected individual for future genomics and stem cell research. Consent rates were compared between pediatric and adult patients and factors affecting consent were analyzed by using multiple logistic regression analysis.

RESULTS

From 2008 to 2011, 3637 patients were approached. A total of 2717 pediatric patients consented (90% consent rate); mean age was 8.5 ± 5.8 years (57% male; 76% white). A total of 561 adult patients consented (92% consent rate, P = .071 versus pediatric). Factors associated with lower pediatric consent rates included younger age, race, absence of complex defects, and location of consent; these were not associated with adult consent rates. Leading causes for refusal of consent were lack of interest in research (43%), overwhelmed clinically (14%), and discomfort with genetics (11%). Concerns related to privacy, insurability, indefinite storage, and ongoing access to medical records were not the leading causes for refusal.

CONCLUSIONS

The high pediatric consent rate (90%) was comparable with that of adults. Ethical, social, or legal issues were not the leading reasons for refusal of consent.

Inclusion of residual tissue in biobanks: opt-in or opt-out?

Residual samples are an important source of tissue for biobanks. They refer to leftover tissue that is obtained in the course of clinical care. Residual samples can be included through an opt-in method--that is, a person explicitly expresses consent to include residual tissue--or an opt-out method--that is, the tissue is stored unless a person explicitly refuses. At the moment there is a renewed interest in the appropriate method for the inclusion of residual samples in biobanks. The expansion of biobanks and rapid developments in biomedical research underscore the need to evaluate the proper procedure. In this article we revisit the arguments in favor and against opt-in and opt-out methods for residual tissue research. We conclude firstly that an opt-out method is only justifiable when certain conditions are met: (1) awareness has to be raised, (2) sufficient information has to be provided, and (3) a genuine possibility to object has to be offered. An opt-out procedure that fulfills these conditions can be called a "thick" opt-out method. As a consequence, the dichotomy between opt-in and opt-out is less stark than usually suggested, as both methods require a certain amount of effort. Secondly, we conclude that because of the diversity of tissue and research, not every situation can be treated alike. There are at least four situations that require opt-in procedures: (1) research with higher risks or increased burdens, (2) the use of controversial or high-impact techniques, (3) research on sensitive tissue types, and (4) research involving vulnerable patients. We suggest that further interdisciplinary debate should answer the question when to opt-in or when to opt-out.

Parental Perspectives on a Pediatric Human Non-Subjects Biobank

BACKGROUND: Genomic biorepositories will be important tools to help unravel the effect of common genetic variants on risk for common pediatric diseases. Our objective was to explore how parents would respond to the inclusion of children in an opt-out model biobank. METHODS: We conducted semi-structured interviews with parents in hospital-based pediatric clinics. Participants responded to a description of a biorepository already collecting samples from adults. Two coders independently analyzed and coded interviews using framework analysis. Opt-out forms were later piloted in a clinic area. Parental opt-out choices were recorded electronically, with opt-out rates reported here. RESULTS: Parents strongly supported medical research in general and expressed a high level of trust that Vanderbilt University would keep their child's medical information private. Parents were more likely to allow their child's sample to be included in the biorepository than to allow their child to participate in a hypothetical study that would not help or harm their child, but might help other children. Only a minority were able to volunteer a concern raised by the description of the biobank. The opt-out rate was initially high compared with the opt-out rate in the adult biorepository, but after the first week decreased to near the baseline in adult clinics. CONCLUSION: Parents in our study generally support an opt-out model biobank in children. Most would allow their own child's sample to be included. Institutions seeking to build pediatric biobanks may consider the human non-subjects model as a viable alternative to traditional human-subjects biobanks.

Consent to DNA collection in epidemiological studies: findings from the Whitehall II cohort and the English Longitudinal Study of Ageing

PURPOSE

Epidemiological studies increasingly include DNA sampling in their protocols, but participation may vary by demographic, psychological, or health characteristics. This analysis explored sociodemographic (age, gender, religion, and education), health-related, and psychological predictors of participation in genetic data collection in two large epidemiological studies: the Whitehall II cohort and the English Longitudinal Study of Ageing. DNA consent in both studies was not obtained on initial enrollment, but after long-standing participation in the study.

METHODS

Study participants who accepted or declined DNA sampling were compared.

RESULTS

Very few participants declined DNA sampling; 1.6% in Whitehall II and 1.0% in English Longitudinal Study of Ageing. In both cohorts, participants who declined were more likely to be female, nonwhite, and involved in religious activities; although only the ethnic effect consistently survived multivariate analyses. Decliners also felt less in control of events in their lives than those who consented, and this remained significant in multivariate analysis in the English Longitudinal Study of Ageing sample.

CONCLUSION

Consent to DNA sampling was very high in two established UK cohort studies. Differences between the subset of the population unwilling to provide DNA samples and those who consented were modest, although this may be due to the highly selected populations in these cohorts. However, our findings suggest that a greater proportion of decliners would create an important source of selection bias.

Engaging African-Americans about biobanks and the return of research results

We conducted a deliberative engagement to assess attitudinal changes regarding biobank research, governance, and the return of results. We recruited African-Americans from two Southside Chicago health care facilities that serve communities of very different socioeconomic and educational backgrounds in order to examine similarities and differences within the African-American population. We used a mixed method, deliberative engagement process involving a convenience sample of parents recruited from a Federally Qualified Health Clinic (FQHC) [n = 23] and a university-based practice (UBP) [n = 22]. Four coding categories illustrate similarities and differences between participants from the two different practices: (1) reasons for and against participation; (2) trust and mistrust; (3) return of research results; and (4) religion. Overall, there was strong interest in receiving results, which was a main motivator for participation. While participants from both health care facilities expressed distrust of research, UBP participants also expressed trust in the research enterprise. FQHC participants more frequently mentioned religion. Studies about participation in biobanks often focus on participants' race as the sole significant variable, while our work supports the importance of other demographic factors. Medical researchers must move beyond research analyses that consider the African-American population to be monolithic and value the diversity within it.

IRB decision-making with imperfect knowledge: a framework for evidence-based research ethics review

Here we describe the five steps of evidence-based practice as applied to research ethics review and apply these steps to three exemplar dilemmas: incentive payments in substance abuse research; informed consent for biobanking; and placebo-controlled trials involving pregnant women in order to demonstrate the potential of empirical data to inform and improve IRB decision-making.

Two large-scale surveys on community attitudes toward an opt-out biobank

Although US research regulations allow for de-identified biorepositories to be developed without formal informed consent from the patients whose samples are included, it is unknown whether this model will be well-received by community members. Based on early evidence that such a biobank could be successful if patients who object have the opportunity to opt-out, Vanderbilt University developed a biorepository named BioVU that follows this model. This study reports the findings from two large-scale surveys among communities important to this biorepository. In the first, a population-based phone survey of Nashville residents, we found that approval for BioVU is high (93.9%) and that this approval is similar among all population groups. A hypothetical biobank that does not obtain some form of written permission is much less well received. In the second, an online survey of Vanderbilt University faculty and staff, we found a higher level of support for BioVU (94.5%) among faculty and staff working throughout the university. In this survey, employees least likely to approve of BioVU are those employees who prefer not to receive medical care at Vanderbilt University. These surveys demonstrate the highest level of approval for a genomic biobank ever reported in the literature, even among groups traditionally cautious about such research. This high level of approval may reflect increasing comfort with genomic research over time combined with the effect that trust in a specific institution can have on approval for an operating biobank compared with approval of a hypothetical biobank.

Genomics really gets personal: how exome and whole genome sequencing challenge the ethical framework of human genetics research

Exome sequencing (ES) and whole genome sequencing (WGS) putatively identify all adverse functional alleles of protein-coding genes. Accordingly, while ES/WGS are transformative new tools for gene discovery in human and medical genetics research, they also generate new manifestations of ethical issues related to the consent process, data sharing, and return of results. These manifestations have yet to be comprehensively framed, due in part to the rapidity with which new technologies for ES/WGS are being applied and because of a lack of empirical data to provide guidance. Accordingly, researchers, funding agencies, and policy makers have largely dealt with these issues intuitively. We explain how use of ES/WGS challenges: (i) models under which informed consent is typically obtained; (ii) how harms associated with data sharing are considered; and (iii) the nature of obligations surrounding unanticipated findings. We provide broad guidance about interim ways to contend with these issues and make broad recommendations for areas for novel resource and policy development.
