Title: Racial and ethnic disparities in cardiac care


1
Racial and ethnic disparities in cardiac
care What evidence exists? What can we
do about it?
A presentation prepared by The Henry J. Kaiser
Family Foundation and The Robert Wood Johnson
Foundation
2
  • Why the urgency to eliminate racial and ethnic
    disparities in health care?

3
Minority populations are disproportionately
affected
  • Cardiac disease
  • Infant mortality
  • Cancer screening and management
  • Diabetes
  • HIV Infections/AIDS
  • Immunizations

4
IOM Report, 2002 Assessing the Quality of
Minority Health Care
Disparities in the health care delivered to
racial and ethnic minorities are real and are
associated with worse outcomes in many cases,
which is unacceptable. -- Alan Nelson, retired
physician, former president of the American
Medical Association and chair of the committee
that wrote the Institute of Medicine report,
Unequal Treatment Confronting Racial and
Disparities in Health Care
5
Evidence shows disparities exist
  • Institute of Medicine Report, 2002
  • The evidence is overwhelming
  • Disparities exist even when insurance status,
    income, age, and severity of conditions are
    comparable
  • Minorities are less likely than whites to receive
    needed services
  • Disparities contribute to worse outcomes in many
    cases
  • Differences in treating heart disease, cancer,
    and HIV infection partly contribute to higher
    death rates for minorities
  • Source Unequal Treatment Confronting Racial
    and Ethnic Disparities in Healthcare, March 2002.

6
Several studies show racial/ethnic differences in
the appropriate delivery of diagnostic tests and
treatment for
  • Heart Disease
  • Cancer
  • Stroke
  • Kidney Dialysis, Transplant
  • HIV/AIDS
  • Asthma
  • Diabetes

Cardiac Care The Weight of the Evidence

Looked at key cardiac interventions
  • Cardiac catheterization
  • Percutaneous transluminal coronary
    angioplasty
  • Thrombolytic therapy
  • Coronary artery bypass graft surgery
  • Drug therapy

Criteria for evaluating the strength of the
evidence
  • A less strong study
  • Did not control for critical variables
  • Had design flaws that potentially undermined the
    validity of the evidence
  • A strong study
  • Had well-defined parameters
  • Had internal validity
  • Measured and controlled for critical variables

18
Study Results
  • 81 of the 158 studies produced from the
    literature search met the inclusion criteria and
    comprised the body of evidence
  • Most of the studies investigated more than one
    cardiac procedure or treatment
  • 44 of the 81 studies are methodologically strong

19
Study Results (Continued)
  • 56 of the 81 studies include data collected
  • Between 1991 and 2001
  • 51 of the 81 studies are based on clinical data
  • 54 of the 81 studies compare only African
  • Americans and whites

care1984-2001
11 studies find no racial/ethnic difference in
care (14)
68 studies find a racial/ethnic difference in
care (84)

likely than whites to receive appropriate care

Weight of the Evidence suggests
  • African Americans are less likely than whites to
    receive catheterization, angioplasty, bypass
    surgery and thrombolytic therapy.
  • These racial/ethnic differences in care remain
    after adjustment for clinical and socioeconomic
    factors, such as heart disease severity and
    insurance.

26
Potential Sources of Disparities in Care
  • Patient-Level
  • Patient preferences
  • Treatment refusal
  • Care seeking behaviors and attitudes
  • Clinical appropriateness of care
  • Health Care Systems-Level
  • Lack of interpretation and translation services
  • Time pressures on physicians
  • Geographic availability of health care
    institutions
  • Changes in the financing and delivery of health
    care services
  • Provider-Level
  • Bias
  • Clinical uncertainty
  • Beliefs/stereotypes about the behavior or health
    of minority patients

Why the Difference?
28
Objectives of the Initiative
  • To bring together leading health care
    organizations to focus attention on the issue
  • To increase awareness of racial/ethnic
    disparities in health care among physicians
  • To spark discussion among providers and solicit
    their input into causes and solutions
  • To continue the drive toward investigation and
    elimination of cardiac disparities
