Moving from Health Disparities to Health Equity• Examination of all aspects of research
process– Recruitment strategies– Consent procedures– Assessment process– Involvement of minority investigators– Cultural and community attitudes
![Page 3: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/3.jpg)
Growing Attention to Minority Recruitment• Greater awareness of disparities
• Questions of generalizability of findings and interventions to women and minorities – NIH regulations introduced in 1993
• Increased pressure to move beyond descriptive/screening studies to clinical trials
![Page 4: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/4.jpg)
NIH Mandate• In 1994 NIH mandated greater inclusion of
women and underrepresented ethnic and racial minorities in NIH funded studies
• Minority recruitment and retention efforts are carefully monitored by NIH
• Efforts have led to a growing literature examining barriers and facilitators of minority research participation
![Page 5: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/5.jpg)
Minority Participation in Biomedical Research• Communities of color remain underrepresented in
biomedical research
• Limited enrollment affects our full understanding of the complex etiology of the disease generalizability of study findings and
• Inequities in research participation reflect disparities in health and healthcare utilization
![Page 6: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/6.jpg)
Examination of Minority Research Participation• Majority of studies have examined
African American participation• Fewer studies of Latino/Hispanic
communities and effects of language differences
• Virtually no data on American Indians and Alaskan Natives
![Page 7: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/7.jpg)
Challenges of African American Recruitment• Recruitment and retention of African
Americans has been described as:– Difficult– Expensive– Minimal return on investment
• Little empirical evidence to guide development and implementation of successful recruitment and retention methods
![Page 8: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/8.jpg)
Recruitment Challenges
• Attitudes and beliefs of the community
• Structural barriers- study design
• Investigator attitudes, beliefs & behaviors
![Page 9: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/9.jpg)
Community Attitudes are Complex and MultifacetedNo single, simple cause for nonparticipation• Distrust
– Research/Researchers– Medical institutions, clinics, providers and universities– Negative experiences and disparities in care
• Lack of Investigator Accountability– Tuskegee – Henrietta Lacks– Johns Hopkins Lead Studies – Confusion about informed consent
• Fear of Adverse Effects• Failure to Form Relationships with the Community
![Page 10: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/10.jpg)
Community Attitudes are Both Positive and Negative• Overall, participants believe research to be
important to study and cure disease, to make discoveries about new medicines or techniques, and to improve health. – “I would volunteer because research benefits
us. We’re the ones that benefit from research”
![Page 11: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/11.jpg)
Lack of Concern about the Needs and Interests of the Community• “We don’t want to work with those drive by
researchers”
• “They come and get what they want and we never hear from them again”
Ballard et al, 2010
![Page 12: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/12.jpg)
Mistrust of Government Funded Studies
“ We don’t trust the science, the scientists, we don’t trust the doctors, and we definitely don’t trust the government”
“The government, you can hardly trust them.”
Scharf et al, 2010
![Page 13: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/13.jpg)
Mistrust of Government Funded Studies
• “I think you have a lot of people who mistrust the government. You start looking at a lot of medical centers, there’s always going to be some link up the chain to some government entity.”
Scharf et al, 2010
![Page 14: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/14.jpg)
Lack of Trust
“Doctors will say things just to get people to agree to the research. But you never know whether they will actually keep their word.”
Williams et al, 2010
![Page 15: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/15.jpg)
No Perceived Benefit• “And it goes back, if you find something, are we ever going
to see it? So truly, why does my participation really matter for anything? If it's not going to produce a product that I'm going to see, why should I be one of the study participants?”
• “I think the deception is when we read studies, they don’t relate to us. They don’t … I mean, they’re about another nationality. They’re not really for African Americans. And they don’t apply to us.”
Williams et al, 2010
![Page 16: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/16.jpg)
Structural Factors• Recruitment Issues
– African Americans may not be asked• AAAPS -85 % of participants screened had never been
approached to participate in a study (Gorelick et al, 2003)– Active vs Passive Strategies
• Active: Face to face contact, direct mailings & telephone calls may be less effective
• Passive: Announcements at churches and meetings, Flyers, Newspaper ads, Information/education programs appear to be more effective
– Participants recruited through mainstream strategies may belong as much to the majority culture as the culture of their minority group
![Page 17: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/17.jpg)
Structural Factors Affecting Participation
• Limited Access– Transportation– Information– Health literacy
• Demands of Participation– Time– Location– Cost
• Inclusion and Exclusion Criteria
![Page 18: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/18.jpg)
Investigator Attitudes and Beliefs
• Awareness of Tuskegee = Cultural Competence
• Need for an immediate response• Few/no attempts to recruit• Insensitive to community customs and
traditions
![Page 19: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/19.jpg)
New Perspectives on Recruitment and Retention of African Americans for AD Studies
• “Less likely to participate (past and/or present state) does not equate to less willing to participate (present and/or future state)”
Ballard, Gwyther & Edmonds (2010)
![Page 20: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/20.jpg)
How do we Increase Participation?
• The mindset and behaviors of the investigator and research staff are the most important criterion for the success of recruitment and retentio
• Recruitment efforts grounded in programs designed to increase resources and access to care are more likely to be successful (Williams et al, 2011)
![Page 21: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/21.jpg)
Strategies to Increase Participation
• Community Investment Models of Recruitment– Collaborative “win-win” approaches
• Social Marketing Methods
![Page 22: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/22.jpg)

verified AD• Agree to follow-up testing (4 year intervals)
and to participate in clinical, epidemiological and genetic research in the area of AD prevention
• 1650 currently enrolled
![Page 24: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/24.jpg)
Understanding Health Disparities from the Community’s Perspective
• Race demographics
• Age demographics
• Socioeconomic status
• Health status
• Values and belief systems
• Traditions customs and social norms
• Territorial boundaries• Turf issues• Neighborhood
demographics
![Page 25: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/25.jpg)
Community Identified Obstacles to Health Parity• Awareness• Education• Economic Status• Preparedness• Transportation• Access to qualified
providers• Poor Health Status
• Systemic Discrimination• Unhealthy Lifestyles• Myths• Stigma• Stereotypes• Mistrust
![Page 26: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/26.jpg)
What Did the Community Require?
![Page 27: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/27.jpg)
Community Education

Putting “Words” into Action
![Page 32: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/32.jpg)
Retention: Strategies• Flexible times and locations offered for
appointments • Contacting participants during evenings and
weekends when necessary• Keeping control participants engaged (monthly
phone calls)• Allowing participants to take breaks from the
study (vs. withdrawing)• Working with additional contacts to locate
participants• Making withdrawal decisions based on individual
cases (vs. solely on # phone calls or time limits)• Demonstration appreciation and respect for time
and effort of participants and their family members
![Page 33: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/33.jpg)
Rationale for Research Participation (Hamilton et al, 2006)
• Willingness to participate differed by age• Older Adults
– Desire and willingness to help others– Value opportunity to improve medical treatments– Opportunity to increase personal knowledge or
improve understanding of health condition – Particularly important if disease is prevalent in
Black community
![Page 34: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/34.jpg)
Rationale for Research Participation (Hamilton et al, 2006)
• Young Adults– Financial incentives– Desire to help others– Personal interest and increased knowledge– Religious commitment to help others– Specific help for family members affected by disease
• Both groups emphasized:– Minority investigators and staff– Oversight from a prominent authority or recognized entity
![Page 35: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/35.jpg)
Summary of NIMH Focus Group Themes :Facilitators
• Clear description of procedure and willingness to answer questions one on one or in small groups
• Continuous engagement in the community– Bringing findings back to the community
• Education from trusted sources– Information presented in honest but positive way– Varieties of options for participation
• Minimize wear and tear on participants– Transportation, flexible hours, stipends, home
testing
![Page 36: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/36.jpg)
Mistrust“ We don’t trust the science, the scientists, we don’t
trust the doctors, and we definitely don’t trust the government”
“The government, you can hardly trust them.”“I think you have a lot of people who mistrust the
government. You start looking at a lot of medical centers, there’s always going to be some link up the chain to some government entity”
![Page 37: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/37.jpg)
Mistrust about Benefits of Participation“And then if it went the other way, extreme, it’s not going
to benefit black people anyhow. So there’s no real … I don’t have any faith in it ..the research”
“ And it goes back, if you find something, are we ever going to see it? … And I'm like, I may never see anything of this. So truly, why does my participation really matter for anything? If it's not going to produce a product that I'm going to see and I'm one of the study participants ?”
![Page 38: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/38.jpg)
Issues of Informed Consent
![Page 39: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/39.jpg)
Challenges to Informed Consent
• Common for participants to forget, deny or misunderstand consent information– VA Study (1998)
• 72 % unaware that they were participating in a study• Of these, 75 % believed that the study treatment would
be beneficial• Need for more consistent, simpler presentation and discussion
with potential participants
![Page 40: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/40.jpg)
Informed Consent Process & Ethical Demands on the Investigator• Process of informed consent requires some
reasonable attempt on the part of the investigator to help potential participants understand what is being asked of them
• Commitment to helping potential subjects gain enough information to assure autonomous and voluntary participation
![Page 41: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/41.jpg)
Studies of the Process of Consent in Clinical Trials• Repeatedly demonstrate that regulatory
requirements are met-but the consent documents have little impact on patient knowledge or decisions about participation
• Problems with understanding of the concept of informed consent
• Difficulty understanding and interpreting the language of the consent forms
![Page 42: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/42.jpg)
Language and Comprehension Issues
• Difference between “knowing” and understanding
• Recent study of 114 US medical school web sites examined consent form templates and found that the majority of IRB provided texts failed to meet the recommended reading standards
![Page 43: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/43.jpg)
Issues of Informed Consent in African Americans (Corbie-Smith et al. 1999)• Many barriers to recruitment and retention
of African Americans for clinical research• Historic mistrust of doctors, scientists and
the government• Concerns about ethical conduct of clinicians
and investigators when poor and minority patients involved
![Page 44: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/44.jpg)
Lack of Trust
• Language used in consent forms may have very different meanings to others.
• For example the word “trial” seems emotionally neutral-but potential participants report that this means they will be treated like a person on trial-the anticipated study experience: – They will be questioned and cross-examined as if not
telling the truth
![Page 45: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/45.jpg)
Limited Understanding of the Consent Process• Participants believed that the purpose of the
consent document was to protect doctors and hospitals from any legal responsibility.
“If you give consent you don’t have any legal rights. When you sign that paper, you sign all of your rights away, because they have disclaimers all neatly typed up, reviewed by their lawyers to protect themselves from being sued”
![Page 46: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/46.jpg)
Lack of Trust• “Doctors will say things just to get people to agree to
the research. But you never know whether they will actually keep their word.”
• Language used in consent forms may have very different meanings to others. For example the word “trial” seems emotionally neutral-but potential participants may think that they will be treated like a person on trial-questioned and cross-examined as if not telling the truth
![Page 47: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/47.jpg)
Improving the consent process:• Establish a relationship and gain the trust of the
community• Seek input and advice about the language and
format of the consent form and process• Use multiple forms of information (written, audio,
video) and allow time for review and questions• Acknowledge the importance of significant others in
the decision making process
![Page 48: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/48.jpg)
Summary of Findings• The primary and fundamental reason for African Americans’
lack of participation research is pervasive mistrust of the healthcare system.
• Negative perceptions of healthcare providers and health care infrastructure persist due to historical events, institutional racism, and healthcare disparities.
• Adverse perceptions of health professionals extend to perceptions of clinical researchers.
• Other barriers to research participation included:– Fear of the unknown and adverse effects– Insufficient dissemination of information in the African American
community– Inconvenience– Reputation of the researcher/research institution.
![Page 49: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/49.jpg)
Summary of Findings-• Enhancing African American Participation
– Honest respectful communication– Engagement with community– Contact with physician investigators– Use of additional media to explain the research– Extra time for participant to confer with family and
friends– Financial incentives– Sharing findings with the community
![Page 50: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/50.jpg)
Social Marketing
• Social marketing uses the principles of product marketing to encourage people to change their behavior for a social good
• Social marketing techniques have been used in public health to promote health behavior change
![Page 51: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/51.jpg)
Social Marketing and Study Recruitment
• Investigators apply principles to increase recruitment and retention– Product– Price– Promotion– Place
![Page 52: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/52.jpg)
Social Marketing
• Product: Study participation – What do we want the potential participant
to do ?– What does he/she stand to gain by
participation
![Page 53: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/53.jpg)
Social Marketing• Price- What are the “costs” to participation ?
– Tangible • Time• Discomfort• Study related expenses
– Intangible• Changes in beliefs or habits• Questions from family and friends• Loss of privacy
![Page 54: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/54.jpg)
Social Marketing
• Promotion- How to we convey our message ?– Information about study goals and
procedures– Who delivers the message– How is participation presented –recruitment
message
![Page 55: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/55.jpg)
Social Marketing
• Place –where does recruitment take place– The way the request is made– Where the research occurs
![Page 56: Working with Underserved Populations for Research- Challenges and Successful Methods](https://reader035.vdocuments.mx/reader035/viewer/2022062501/56816807550346895ddd8ade/html5/thumbnails/56.jpg)
