Making epidemiologic studies responsive to the needs of participants and communities: the Carolina Breast Cancer Study experience

Why do people participate in epidemiological research?

Many assumptions are made about public willingness to participate in epidemiological research, yet few empirical studies have been conducted to ascertain whether such assumptions are correct. Our qualitative study of the public and of expert stakeholders leads us to suggest that people are generally prepared to participate in epidemiological research, particularly if it is conducted by a trusted public institution such as a government health department, charity, or university. However, there is widespread community distrust of research conducted or sponsored by pharmaceutical companies. Individuals are prompted to take part if the study concerns an illness they or a family member or friend have personally experienced or if they believe the research will confer a widespread public benefit. Preferences vary about the mode of contact for the research to be conducted. Willingness to participate in telephone surveys has decreased in recent years, and this may be a consequence of an increase in calls to homes by telemarketers and market researchers. Participants also stressed the importance of knowing where their names and contact details were sourced and suggested that this information be available to prospective study participants as a matter of course in the first approach or letter. We provide valuable information to epidemiologists in designing studies.

Community-based HIV clinical trials: an integrated approach in underserved, rural, minority communities

BACKGROUND

Although racial and ethnic minorities have disproportionately high rates of HIV infection, these groups are underrepresented in HIV-related clinical trials. This illustrates the need for more innovation in attempts to engage underrepresented populations in calls for interdisciplinary and translational research.

OBJECTIVES

Eleven focus groups and 35 interviews were conducted with people living with HIV/AIDS (PLWHA) to explore the perspectives of rural community leaders, service providers, and PLWHA about bringing HIV-related research, including clinical trials, into rural communities.

METHODS

Over a period of 3 months in spring 2007, we collected qualitative data from three sources: Community leaders, service providers, and PLWHA. Text data were analyzed using the constant comparative method and content analysis techniques of theme identification.

RESULTS

Respondents want an integrated approach to HIV research that builds trust, meets community needs, and respects their values. They conceptualize HIV research as part of a broader spectrum of HIV testing, prevention, and care, and suggest integrating HIV trials with existing community services, organizations, and structures, engaging various segments of the community, and conducting research using a personal approach.

CONCLUSIONS

These findings support calls for more relevant, translational, and engaged research. An integrated approach may be an important innovation to transform the research enterprise to meet these goals and more directly improve the health of individuals.

Status, challenges and facilitators of consumer involvement in Australian health and medical research

Background

The emergent international practice of involving consumers in health research is driven, in part, by the growing share of health research that can only be applied in and emerge from knowledge that is shaped by human values and societal contexts. This is the first investigation of its kind to identify the current prevalence, challenges, enabling factors and range of approaches to consumer involvement in health and medical research in Australia.

Methods

A nation-wide survey of research funding organisations and organisations that conduct research was performed during 2008-2009.

Results

Marked variation in consumer involvement experience and perceptions exists between research funders and researchers. Research funders were over eight times more likely than organisations conducting research to involve consumers in identifying research needs and prioritising research topics. Across both groups, practical and time constraints were reported as key challenges to involving consumers, while guidelines on consumer involvement and evidence of effect were the most important potential enablers. More than a third of research organisations indicated that when consumer involvement was a condition of research funding, it was an important facilitator of involvement.

Conclusion

It is no longer simply enough to keep society informed of important scientific breakthroughs. If Australian health research is to take into account important social contexts and consequences, it must involve consumers. A set of minimum consumer involvement standards and associated guidelines, that are agreed and routinely adopted, could ensure that consumers and the Australian community they represent, are given an opportunity to shed light on experiences and local circumstance, and express views and concerns relevant to health research.

Involving people affected by cancer in research: a review of literature

The purpose of the literature review was to find out why people affected by cancer have been involved in research; how they have been involved and the impact of their involvement. We used systematic methods to search for literature, applied inclusion and exclusion criteria, conducted a quality appraisal, selected relevant data from the included articles for analysis, and provided a narrative summary of these data. The literature shows that people affected by cancer, particularly women with breast cancer, have been involved in a range of research programmes, projects and initiatives especially in the USA, UK, Canada and Australia. Their involvement has impacted upon research design, accrual and response rates. There is increasing recognition of the need for an infrastructure, including formal recruitment procedures, training and mentoring, to support an agenda of involvement and a need to challenge the ethos of traditional research, which does not easily lend itself to this agenda. Further critique of the role of 'experiential knowledge' in research is required so that researchers and people affected by cancer can work in partnership.

Ethical, legal, and social implications of biobanks for genetics research

The elucidation of the causes of complex diseases pivots on understanding the interaction between biological (genetic) and environmental factors that give rise to disease risk. The modest effects of genetic factors in complex diseases supports the need for large-scale studies of high-quality human biological materials, paired with detailed clinical data, to adequately detect these effects. To this end, biobanks or biorepositories have been developed around the world, by public and private entities alike, to provide researchers the opportunity to study collections of human biospecimens annotated with clinical and other health-related measurements. It has been estimated that more than 270 million tissue samples are stored in the U.S., expanding at a rate of approximately 20 million samples annually. In this chapter, we discuss several ethical, legal, and social issues that have been raised surrounding biobanks, including recruitment of vulnerable populations, informed consent, data disclosure to participants, intellectual property, and privacy and security. Throughout the chapter, we will highlight experiences of national biobanks in Iceland, the U.K., Sweden, and Estonia, and the proposal for a U.S. population cohort study. The dependence on public participation requires clear and transparent policies developed through inclusive processes.

Beyond scientific rigour: funding cancer research of public value

OBJECTIVE

To identify the values deemed by cancer consumers and community members to be important in judging research, and develop an appraisal instrument for the inclusion of consumer and community values in cancer research funding decisions in an independent review process.

BACKGROUND

Improvement in the level and quality of consumer involvement in research processes is becoming increasingly recognised as an important area of development in research governance. It was identified that while the current practice of selecting research based on scientific merit satisfies the need to fund research with the best scientific quality and potential for success, this may not necessarily satisfy all the needs and expectations of cancer consumers and the wider community.

METHODS

A research team was established to undertake the qualitative study. A combination of focus groups and semi-structured in-depth telephone interviews were conducted to collect and verify information about the values held by cancer consumers and the wider community with regard to research.

RESULTS

Consumer review criteria to guide consumers in judging the value of research, optimal rating scales to use with these criteria and views on how consumer needs should be incorporated into the process of judging and allocating research grants (e.g. the relative weight that should be given to scientific and consumer review) have been formally identified by this research.

CONCLUSIONS

The findings of this study clarify consumer and community values regarding cancer research funding and offer a means to evaluate research that address these values.

A review of literature about involving people affected by cancer in research, policy and planning and practice

OBJECTIVE

To systematically review the literature on involving people affected by cancer in healthcare research, policy and planning and practice.

METHODS

Database searches, cited author, and grey literature searches were conducted.

RESULTS

131 documents were included. Rationales for the agenda of involvement represent two polar characteristics of modernity: individualism and collectivism. In research, people acted as advocates, strategists, advisors, reviewers and as participatory researchers. In policy and planning, people were involved in one-off involvement exercises and in longer-term partnerships. Men, those with rare cancers, children, and people who are socially deprived have been rarely involved. There is little research evidence about the impact of involvement. Training and information, resources and a change in attitudes and roles are required to implement an agenda of involvement.

CONCLUSION

The USA, the UK, followed by Canada and Australia have promoted an agenda of involvement.

PRACTICE IMPLICATIONS

A dissemination strategy to share good practice; involvement of all types of people; an individualised and flexible approach; training, resources and a shift in thinking from paternalism towards partnership working are required. More research is needed about the impact of involvement and relationships between rationales for involvement and implementation.

Ethical issues in identifying and recruiting participants for familial genetic research

Family-based research is essential to understanding the genetic and environmental etiology of human disease. The success of family-based research often depends on investigators' ability to identify, recruit, and achieve a high participation rate among eligible family members. However, recruitment of family members raises ethical concerns due to the tension between protecting participants' privacy and promoting research quality, and guidelines for these activities are not well established. The Cancer Genetics Network Bioethics Committee assembled a multidisciplinary group to explore the scientific and ethical issues that arise in the process of family-based recruitment. The group used a literature review as well as expert opinion to develop recommendations about appropriate approaches to identifying, contacting, and recruiting family members. We conclude that there is no single correct approach, but recommend a balanced approach that takes into account the nature of the particular study as well as its recruitment goals. Recruitment of family members should be viewed as part of the research protocol and should require appropriate informed consent of the already-enrolled participant. Investigators should inform prospective participants why they are being contacted, how information about them was obtained, and what will happen to that information if they decide not to participate. The recruitment process should also be sensitive to the fact that some individuals from families at increased genetic risk will have no prior knowledge of their risk status. These recommendations are put forward to promote further discussion about the advantages and disadvantages of various approaches to family-based recruitment. They suggest a framework for considering alternative recruitment strategies and their implications, as well as highlight areas in need of further empirical research.

Racial Differences in Enrolment in a Cancer Genetics Registry

Background: Lower enrolment of minorities into research studies has been reported frequently. Most studies have little information about nonparticipants, making it difficult to identify characteristics associated with enrolment and how they might vary by race. Methods: Women who had previously participated in a population-based, case-control study of breast cancer in North Carolina were invited to enrol in a cancer genetics registry. Detailed questionnaire data on sociodemographic characteristics and cancer risk factors were available for all women. We compared characteristics of women who agreed to be in the registry with those who were deceased, were unlocatable, or declined enrolment. Unconditional logistic regression analyses were done to identify predictors of enrolment. Results: Enrolment rates were markedly lower among African Americans than Whites (15% and 36%, respectively) due to both lower contact rates (41% versus 63%) and lower enrolment rates among those contacted (37% versus 58%). Logistic regression models suggested that racial differences in enrolment were not due to socioeconomic characteristics or other cancer risk factors; race was the only significant predictor of enrolment in multivariable models (odds ratio 0.41, 95% confidence interval 0.23-0.72). Conclusions: Although all women had previously taken part in a research study, African American women were less likely to enrol in the cancer genetics registry than White women. A possible explanation of these findings is that studies of genetics may present particular concerns for African Americans. Further research is needed to identify attitudes and issues that present barriers to participation among minorities.

The partnership between breast cancer advocates and scientists

The National Breast Cancer Coalition (NBCC) is a grassroots organization that represents breast cancer advocates and is committed to eradicating breast cancer. NBCC defines a breast cancer advocate as someone who has been personally affected by the disease (e.g., a breast cancer survivor, family member, or friend), represents a constituency, and is motivated to join the fight against the disease. One of the organization's goals is to ensure that breast cancer advocates have a seat at the table when decisions are made about breast cancer research and policy. To accomplish this goal, NBCC educates advocates so that they can participate in and make meaningful contributions to legislative, scientific, and regulatory decision-making bodies. In addition to creating educational opportunities for advocates, NBCC has spearheaded several initiatives designed to directly increase the quality and quantity of breast cancer research. NBCC has also played a major role in making funding available to breast cancer researchers. Two of NBCC's most notable programs include Project LEAD, an intensive science-training course for breast cancer advocates, and the Environmental Initiative, a collection of activities designed to improve research into the relationship between breast cancer and the environment. Breast cancer advocates trained by NBCC have partnered with the scientific community and individual scientists to improve the peer review, design, and implementation of breast cancer research.
