Evidence of Racial and Ethnic Disparities in Healthcare
  • Disparities consistently found across a wide range of disease areas and clinical services
  • Disparities are found even when clinical factors, such as stage of disease presentation, co-morbidities, age, and severity of disease are taken into account
  • Disparities are found across a range of clinical settings, including public and private hospitals, teaching and non-teaching hospitals, etc.
  • Disparities in care are associated with higher mortality among minorities (e.g., Bach et al., 1999; Peterson et al., 1997; Bennett et al., 1995)

What are Potential Sources of Racial/Ethnic Health Care Disparities?
  • Health systems-level factors – financing, structure of care; cultural and linguistic barriers
  • Patient-level factors – including patient preferences, refusal of treatment, poor adherence, biological differences
  • Disparities arising from the clinical encounter

15
Potential Sources of Disparities:  The Clinical Encounter
  • Patients’ attitudes toward health care and preferences for treatment


  • Physicians’ conscious and unconscious stereotypes and biases


  • Characteristics of health care settings that may encourage stereotypes and biases – time pressure, resource constraints, complex problems
16
Effects of Stereotyping: What the Research Shows
  • Stereotypes:


  • Can exert powerful effects on thinking and actions at an implicit, unconscious level, even among well-meaning, well-educated persons who are not overtly biased.


  • Can influence how information is processed and recalled.


  • Can exert “self-fulfilling” effects, as patients’ behavior may be affected by providers’ overt or subtle attitudes and behaviors.

The Role of Accrediting Organizations
  • Encourage data collection and monitoring for disparities in access to and quality of care
  • Encourage the development, implementation and evaluation of system-wide “cultural competency” interventions
  • Encourage diversity efforts in health professions schools and, among hospitals and health systems, recruitment of underrepresented minority health professionals
