Diabetes in the African-American Medicare population. Morbidity, quality
of care, and resource utilization.
Diabetes Care 1998;21(7):1090-5.
The goal of this study was to determine whether African-American Medicare
beneficiaries with diabetes are at special risk for poor health, sub-optimal
preventive care, and high national expenditures. Data were derived from
patient interviews conducted among Medicare beneficiaries who were aged
65 years or older in 1993 and who had diabetes.
African Americans and whites with diabetes had a similar number of comorbidities
and diabetic complications; however, African Americans had worse health
perception. The rates for quality of care, which included receipt of regular
laboratory tests and preventive procedures and visits to an ophthalmologist,
were low. In general, African Americans were less likely than whites to
have these procedures (both in univariate analyses and after controlling
for gender, age, and education). Race differences with regard to these
variables were particularly potent among women, the elderly (at least
85 years), and those with less than a high school education
African Americans had higher reimbursements for the use of home health
services, skilled nursing facilities, outpatient services, medicines,
and "other physician." With regard to overall resource utilization,
total reimbursement was slightly higher for African Americans, but after
adjusting for age, sex, education, and measures of health status, race
was not statistically significantly associated with reimbursement (p=0.09).
While their average number of visits to a physician per year was significantly
lower, American Americans were more likely to make emergency visits than
whites. There was no racial difference in “having a health problem
that warranted a physician visit, but not seeking care” (15% of
African Americans versus 9% of white reported this, p=0.15). However,
compared with whites, African Americans were less likely to be "very
satisfied with the ease of getting to a doctor from where they lived"
(p=0.06).
The authors point out that even though older African Americans were less
likely than whites to receive processes associated with reduced morbidity
in younger patients, their rates of diabetic complication were similar.
The similar complication rates may reflect a weaker linkage between these
processes of care and outcome in older patients than among younger patients.
Thus, the results of this study indicate that the most appropriate measures
of high quality care for older people are unclear.
The authors conclude that "these [racial] discrepancies [in receiving
several recommended services] may reflect a preference by African Americans
to avoid medical testing and procedures, but they could also result from
a less aggressive treatment style by physicians toward African Americans,
or difficulty by African Americans in gaining access to the health care
system".
