Background

• Large body of evidence from the US demonstrating racial/ethnic inequalities
in access to health care and outcomes of health care.

• Insurance status is a key (but not the only) determinant of these.

• US healthcare systems with universal access (military and veterans Affairs)
appear to have fewer inequalities.

• But evidence from the NHS, although limited, also suggests inequalities:
• Greater use of primary care is not matched by greater use of secondary care;
• Higher levels of dissatisfaction with care received;
• Longer waits for appointments;
• Poorer quality of practice infrastructure;
• Language barriers during the consultation;
• Less likely to get follow up services after initial consultation;
• Longer waits for referral to specialist care;
• Less likely to receive specialist treatments (revascularisation and thrombolysis).

Objectives

• Examine ethnic inequalities in access to health care:
• Primary care (GP and Dentist);
• Out- and day-patient hospital care;
• In-patient care.

• Examine ethnic inequalities in the outcomes of care received for:
• Hypertension
• Raised cholesterol
• Diabetes


Methods: sample and data collection

• Health Survey for England, ethnic minority (1999 and 2004) and
cardiovascular (1998 and 2003) years
• Those aged 16-74
• Nationally representative samples (but does not include ethnic minority people
living in very low density areas)
• Stratified (NHS regions and socioeconomic profiles) and clustered sample
• Addresses identified using the Postcode Address File (except the Chinese sample)
• Ethnic minority sample also stratified according to Census data on ethnic density
• Response rates vary by ethnicity (individual rate 60-70%)

• Ethnicity classified according to family origins
• Gives a large sample of Irish, Black Caribbean, Indian, Pakistani, Bangladeshi
and Chinese respondents
• Language matched interviewers

Methods: measures for access

• Visited a GP for consultation in the last two weeks (HSE 1999 only)

• Been an in-patient (stayed overnight or longer) in the last year

• Attended a hospital as an out- or day-patient in the last year

• Have regular or occasional check-ups with a dentist (HSE 1999 only)

• Analysis using stata and accounting for sample weights (to adjust for
unequal probabilities of selection) and for the stratification and
clustering of the sample

• Models initially adjusted for age and gender; then for self-assessed
health and limiting longstanding illness

Methods: measures for outcome of care

• Hypertension (diagnosed or measured ≥ 140/90)
• Hypertensive controlled: BP < 140/90 but report diagnosis or treatment
• Hypertensive uncontrolled: BP ≥ 140/90 and report diagnosis or treatment
• Hypertensive undiagnosed: BP ≥ 140/90, but no report of diagnosis or treatment

• Raised total cholesterol (diagnosed or measured ≥ 5mmol/l)
• Controlled: cholesterol < 5 mmol/l but report diagnosis or treatment

Conclusions (1)

• No inequalities in access to GP services
• No inequalities in outcomes of care for hypertension, raised
cholesterol and, possibly, diabetes

• Some inequalities in access to hospital services (particularly use of
out- and day-patient services)
• Marked inequalities in access to dental services

• Limited subset of (important) conditions – contrary findings for other
conditions and for reported levels of satisfaction with care received
• Conditions largely managed in primary care settings
• Response rates, sample size and power


Conclusions (2)

• Marked similarities between the US and UK in terms of ethnic
inequalities in health and socioeconomic position

• Marked differences in terms of access to and outcomes of healthcare

• The effect of differences in healthcare systems – a health service with
universal access?

• But discrepancy between primary care and secondary care in
England
• Differences in thresholds triggering primary care consultation (lack of
evidence)
• Differences in thresholds for referral by practitioners (contradictory
evidence)
• Use of private care (some limited evidence)
