Reducing disparities in clinical trials


Three friends-Jim, Bill and Peter-- were walking down the street. Jim said, "I gave blood today." Peter said, "That's terrific! You are a scholar and a gentleman."

Bill said, "After a lot of thought, I've decided to donate a kidney." Jim said, "That's beyond terrific! You are a prince among men."

Peter said, "Well, I'm not giving blood, and I'm not donating a kidney, but I plan to enroll in a clinical trial tomorrow." Jim and Bill said, "What? Are you crazy?"


Characteristics of successful studies
Characteristics of successful studies

  • Continuing medical education for physician and staff

  • Printed educational materials for subjects

  • Incentives to patients

  • Use of local opinion leaders

Low minority participation
Low Minority Participation

  • Minorities are less likely to enroll in studies compared to white males

  • Despite high disease burden, less than 5% of participants in Breast and Prostate Cancer prevention trials were minority

  • 1996 to 2002 annual # of trial participants increased from 8,000-12,000 but minority participation decreased. Hispanic & Blacks represented 3.7% and 11.0% in 1996 but down to 3.0% and 7.9% in 2002

Murthy, 2004

Low minority participation1
Low Minority Participation

  • Local Data:

    Fox Chase Cancer Center (Northeast Philadelphia)-data from 2004

    Catchment area: 18% Black, 6% Hispanic, 3% Asian, 71% White

    Minority patient accrual: 8% Black, 2% Hispanic, 1% Asian, 89% White

    Minority patient recruitment: 6% Black, <1% Asian and Hispanic each

Bruner, 2006

Reducing disparities in clinical trials

Minority Participation: UH Experience

  • UMDNJ – University Hospital (UH) data

    In 2007 there were 1132 newly identified cancer patients: 32% white NH, 35% black NH,

    23% Hispanic.

    There were 43 active cancer trials that enrolled a total of 54 patients, representing an overall enrollment rate of 4.8%.

    5.1% of blacks enrolled (20/396)

    4.6% of Latinos enrolled (12/260)

    Thus, participation rates among racial and ethnic groups were similar at UH.

Barriers to patient participation
Barriers to Patient Participation

  • Demands of the study

  • Preference for a particular treatment

  • Concerns about side effects

  • Comfort level with physician

  • Language and literacy

  • Loss of privacy

  • Portrayal as guinea pig

Distrust as a barrier to participation
Distrust as a Barrier to Participation

  • Mistrust of scientific investigators and of academic institutions were major barriers among Blacks

    Providing informed consent was reported as relinquishing rather than protecting rights

    Research volunteer is considered a“guinea pig”

    Knowledge of the Tuskegee Syphilis Study was not necessarily negatively associated with willingness to participate

Yancey, 2006

Barriers to recruiting minorities for cancer trials
Barriers to Recruiting Minorities for Cancer Trials

  • Systematic review to determine barriers to participation of underrepresented populations in cancer trials: 1966-2005

    Barriers to:

    -trial awareness

    -opportunity to participate (research design, provider attitudes)

    -acceptance of enrollment (perceived harms, mistrust)

    --additional barriers related to cultural factors

Ford, 2007

Barriers to recruiting minorities for cancer trials1
Barriers to Recruiting Minorities for Cancer Trials

Examination of Community Members’, Researchers’ and Health Professional perceptions of barriers to minority recruitment (Robinson JM, 2007)

  • Cluster: Recruitment Issues

    Minorities unaware of medical research

    Lack of cultural sensitivity in communications

    Lack of resources to treat the uninsured if found to be sick

  • Cluster: Patient concerns

    Lack of awareness of benefits to participation

    Sense that subjects only give and get nothing

    Concerns about signing ICF

  • Cluster: Fears

    Fear of being a guinea pig

    Fear of unknown

Barriers to recruiting minorities for cancer trials2
Barriers to Recruiting Minorities for Cancer Trials

Cluster: Psychosocial/socioeconomic issues

More pressing survival problems

Cultural beliefs/Religious beliefs

Mental illness, homelessness

Cluster: History/past experiences

Previous negative experience

Literacy issues

Mistrust due to discriminatory social/historical/legal experiences

Cluster: Resources/Financial considerations

Lack of health coverage to reimburse medical interventions in protocol

Presentation at late stage for many minority patients

Dismal past record of translating research into practice in underserved community

Barriers to recruiting minorities for cancer trials3
Barriers to Recruiting Minorities for Cancer Trials

  • Cluster: Research System Issues

    Lack of adequate MD education in providing patient’s information about trials

    Lack of incentive for overworked MDs caring for minorities Inappropriate outreach methods

  • Cluster: Researcher Bias

    MD fear of losing patients

    Poor Relationship between medical institution and community

    Lack of follow-up

  • Cluster: Issues in Research Method, Design, Management

    Not linking research to what minority communities need

    Lack of minorities as PI

    Lack of bilingual researchers

Recruitment efforts
Recruitment Efforts

  • NIH Revitalization Act mandated minority inclusion in randomized clinical trials, 1993

  • Review criteria in NIH study sections have formally required minority recruitment or scientific justification for their exclusion

  • Rep. Edolphus Towns (Democrat, NY) was expected to submit legislation that would offer delayed generic competition to companies that conduct minority focused clinical trials.

Recruitment categories
Recruitment Categories

  • Passive-disseminating information in the target population via flyers, advertisements, mailings, public service announcements

  • Active-bringing the project staff directly into contact with prospective participants via telephone or in-person appeals by project staff and medical providers

Recruitment strategy community involvement
Recruitment Strategy: Community involvement

  • Use lay outreach workers from the targeted population (cultural insider)

  • Community-based organizations particularly for Blacks

  • Places of Worship: Although some investigators have identified religiosity as a barrier due to a fatalistic view of disease –others have found religiosity to be positively associated with willingness to participate

Reducing disparities in clinical trials

What is it? participate

One day educational program free and open to the public

Local physician speakers provide information to help people make informed decisions about clinical research participation

General session lecture – “What Clinical Research Means to You!”

Educational workshops – focused on disease states and issues such as women or minorities in clinical research

Patient Panel – real life stories of clinical research participation

Reducing disparities in clinical trials

Purpose and Value participate

Takes awareness-building into the heart of the community via traditional outreach and advocacy strategies

Builds a grass-roots movement by engaging and informing political figures, opinion leaders, physicians, healthcare providers and other stakeholders

Changes perception of the clinical research participant from that of “guinea pig” to that of Hero

Reducing disparities in clinical trials

Attendee Evaluations participate

Self-reported knowledge of the clinical research process: Attendees who were not previously in a clinical trial

n = 66

n = 65

Before AWARE for All

After AWARE for All

Reducing disparities in clinical trials

Attendee Evaluations participate

Likelihood of participating in a clinical trial:

n = 108

Recruitment strategy minority principle investigators
Recruitment Strategy: Minority Principle Investigators participate

  • Minority investigators are under-represented among the pool of all active clinical investigators (Getz, 2008)

Recruitment strategy friendly informed consent
Recruitment Strategy: Friendly Informed Consent participate

  • Health literacy: degree to which people can obtain, process and understand basic health information and services they need to make appropriate health decisions. It is not just about reading and writing, but includes all the ways people communicate health information such as by speaking, drawing pictures and using technology.

  • Most consents are on a 12th grade reading level

  • Provide consent in different languages, use “comfort” words, pictures, diagrams

  • Voice-enhanced ICF

  • Yates, 2009 developed a 23 page ppt flip chart for an IC-study comparing traditional cardiac rehab vs home-based cardiac rehab-improved participation rate from 22%-54%

Recruitment strategy clinical trial alert systems
Recruitment Strategy: Clinical Trial Alert Systems participate

  • Configured the EHR to trigger an alert if a patient is likely eligible for an ongoing clinical trial

    CTA is set to trigger only during clinical encounters

    If MD elects to proceed , a customized CTA order form appears—reminds MD to assess a few additional eligibility criteria

    MD clicks appropriate box 1) yes patient meets criteria and is interested;2. No, patient does not meet criteria; 3. No patient meets criteria but not interested. Message sent to trial coordinator’s workstation

  • CTA addresses obstacles to MD participation in recruitment

Recruitment strategy general
Recruitment Strategy: General participate

  • Adequately characterize the target population

  • Involve members of the target population in planning efforts

  • Take message to the target population

  • Give something back to the community

  • Enhance credibility of study by using a community spokesperson

  • Identify and remove barriers to participation

  • Cultural relevance of materials

  • Improve staff sensitivity

  • Stress importance of prevention and early detection

  • Use of women to encourage participation by males

Recruitment strategy print media
Recruitment Strategy: Print Media participate

  • Mass mailing of brochures/flyers with personalized letters -across ethnic groups

  • Secondary source was referral by a friend for Hispanics and Blacks and newspaper ads/articles and brochures for whites

  • Overall recruitment through the health system produced a higher randomization yield than did newspaper and radio public service announcements or faith-based organizations

  • Recruits from faith-based organizations were more likely to stay in the study

New media
New Media participate

  • Study specific websites

  • Email

  • Banner Advertising

  • Chat rooms & forums

  • Podcasts

  • Search engine advertising

Target audience
Target Audience participate

  • Men—newspapers

  • Elderly—TV and newspapers

  • Adult children and spouses of the patient-direct mail, newspapers, radio and online advertising

  • Young mothers--magazines and online advertising

Components of a good ad
Components of a Good Ad participate

  • Creative

  • Get noticed

  • Offers news

  • Compelling message

  • Succinct message

  • Meaningful to patient

  • Use Emotion

  • Pleasing colors

  • Catchy study name

Conclusions participate

  • There is equal willingness among minorities and whites to participate in clinical trials

  • Lack of awareness and lack of understanding of the benefits of participation are probably the biggest obstacles

  • Mistrust remains an issue

  • Community involvement is imperative for enrollment to grow
