importance of poor minority participation in clinical trials
Importance of Poor Minority Participation in Clinical Trials

“Clinical research is a critical resource for the development

of new prevention, diagnosis, and treatment techniques

for a number of diseases….The ability to trust and apply

the results of a clinical trial, as well as transfer them into

clinical practice, is related to the type and number of

patients enrolled in that trial. If trials do not include

minorities, then there is a question of whether or not the

results of the studies are relevant to everyone across the

board.”

http://www.cancer.gov/newscenter/benchmarks-vol6-issue4/page1

importance of poor minority participation in clinical trials1
Importance of Poor Minority Participation in Clinical Trials

“…more than a decade following the institution

of (the) NIH requirement, enrollment of minority

populations into cancer trials remains woefully

inadequate.”

Ford et al. (2005). Evid. Rep / Tech Assess., 122: 1-11.

health disparities
Health Disparities

“Eliminating health disparities will require both

individual and societal efforts.”

health disparities1
Health Disparities

“A population is a health disparity population if

there is a significant disparity in the overall rate

of disease incidence, prevalence, morbidity,

mortality or survival rates in the population as

compared to the health status of the general

population.”

Minority Health and Health Disparities Research and Education Act United States Public Law 106-525 (2000), p. 2498

health disparities experienced by african americans
Health Disparities Experienced by African Americans
  • Account for 13% of the population but 50% of all new HIV infections
  • Age adjusted rate for all cancers is 25.4% higher than for white Americans
  • Diabetes age-adjusted death rate more than twice that for white Americans (49.2 vs. 23.0 per 100,000)
  • Age-adjusted death rate of heart disease 30.1% higher and stroke was 41.2% higher than for white Americans
federal mandates
Federal Mandates
  • NIH Revitalization Amendment 1993
    • Do interventions /therapies studied differentially affect women or men or members of minority groups?
    • Annual reporting of gender and race/ethnicity
    • Cost is not a legitimate reason for excluding ethnic minorities

final thoughts
Final Thoughts
  • More preparation before we design a study
  • Research in the African American community facilitated by communication, trust, and relationship building
  • Importance of cultural competence
