ABSTRACT To extend recent conceptual and methodological advances in disparities research to include the incorporation of genomic information in analyses of racial/ethnic disparities in health care and health outcomes.
Published literature on human genetic variation, the role of genetics in disease and response to treatment, and methodological developments in disparities research.
We present a conceptual framework for incorporating genomic information into the Institute of Medicine definition of racial/ethnic disparities in health care, identify key concepts used in disparities research that can be informed by genomics research, and illustrate the incorporation of genomic information into current methods using the example of HER-2 mutations guiding care for breast cancer.
Genomic information has not yet been incorporated into disparities research, though it has direct relevance to concepts of race/ethnicity, health status, appropriate care, and socioeconomic status. The HER-2 example demonstrates how available genetic information can be incorporated into current disparities methods to reduce selection bias and measurement error. Advances in health information infrastructure may soon make standardized genetic information more available to health services researchers.
Genomic information can refine measurement of racial/ethnic disparities in health care and health outcomes and should be included wherever possible in disparities research.

    ABSTRACT: Biobanking research seeks to improve the diversity, availability, and quality of human specimens critical for translational research, including biospecimen collections from disadvantaged minorities. American rural whites are seldom represented in such initiatives as geographic isolation makes obtaining informed consent challenging. We report a case series of 83 newly diagnosed cancer patients, attending a rural community medical center, who consented to participate in cancer research. To enable pooling with population studies, we created a BioGeoBank using 2007 NCI and ISBER Best Practices, after a protocol approval by Eastern Maine Medical Center (EMMC) IRB and OHP HRPO. Informed consent forms were at Flesch-Kincaid 8th Grade reading level, supplemented by NCI educational brochures. Of 108 patients identified, 85 were eligible. Of these, 83 patients (49 lung cancer, 21 breast cancer, and 13 other cancers) consented to donate data, blood, and tissue specimens for future research, and maintained eligibility. Two years later, we executed a legacy protocol to transfer specimens to NCI's biorepository. Of the 69 surviving patients, 9 patients could not be contacted. All those contacted (60) agreed to provide additional data on environmental risks, and consented to specimen transfer. Self-organizing map analyses showed no evidence that age, education, income, familial susceptibility, or lifestyle factors were associated with consent to donate data or biospecimens. Cancer cases reported 1-3 co-morbid chronic diseases (mostly cardiovascular), near lifetime smoking and/or alcohol consumption; familial cancer risks, and many had a prior cancer history. Anecdotally, willingness to consent was based on altruistic hopes that research would generate knowledge to reduce cancer incidence. Our study shows that cancer patients from disadvantaged white rural communities with health disparities associated with geographic isolation are motivated to consent to participate and support biobank research.

    ABSTRACT: The past decade has witnessed rapid advances in human genome sequencing technology and in the understanding of the role of genetic and epigenetic alterations in cancer development. These advances have raised hopes that such knowledge could lead to improvements in behavioral risk reduction interventions, tailored screening recommendations, and treatment matching that together could accelerate the war on cancer. Despite this optimism, translation of genomic discovery for clinical and public health applications has moved relatively slowly. To date, health psychologists and the behavioral sciences generally have played a very limited role in translation research. In this report we discuss what we mean by genomic translational research and consider the social forces that have slowed translational research, including normative assumptions that translation research must occur downstream of basic science, thus relegating health psychology and other behavioral sciences to a distal role. We then outline two broad priority areas in cancer prevention, detection, and treatment where evidence will be needed to guide evaluation and implementation of personalized genomics: (a) effective communication, to broaden dissemination of genomic discovery, including patient-provider communication and familial communication, and (b) the need to improve the motivational impact of behavior change interventions, including those aimed at altering lifestyle choices and those focusing on decision making regarding targeted cancer treatments and chemopreventive adherence. We further discuss the role that health psychologists can play in interdisciplinary teams to shape translational research priorities and to evaluate the utility of emerging genomic discoveries for cancer prevention and control.

    ABSTRACT: Unprecedented change in the US health care system is being driven by the rapid uptake of health information technology and national investments in multi-institution research networks comprising academic centers, health care delivery systems, and other health system components. An example of this changing landscape is Optum Labs, a novel network "node" that is bringing together new partners, data, and analytic techniques to implement research findings in health care practice. Optum Labs was founded in early 2013 by Mayo Clinic and Optum, a commercial data, infrastructure services, and care organization that is part of UnitedHealth Group. Optum Labs now has eleven collaborators and a database of deidentified information on more than 150 million people that is compliant with the Health Insurance Portability and Accountability Act (HIPAA) of 1996. This article describes the early progress of Optum Labs. The combination of the diverse collaborator perspectives with rich data, including deep patient and provider information, is intended to reveal new insights about diseases, treatments, and patients' behavior to guide changes in practice. Practitioners' involvement in agenda setting and translation of findings into practical care innovations accelerates the implementation of research results. Furthermore, feedback loops from the clinic help Optum Labs expand on successes and give quick attention to challenges as they emerge.
