This paper investigates the difficulties that people encounter in thei
r attempt to obtain needed health services, other than their third-par
ty coverage or lack of it. These problems can be temporal, geographic,
attitudinal, or financial (even with insurance). A state-wide sample
survey conducted in 1989 revealed that about 17% of Michigan's populat
ion experienced one or more of these kinds of difficulties in their at
tempts to receive medical care. Those at greater risk included persons
with public insurance coverage (mostly Medicaid), persons with low in
comes, persons in poor health, women, and members of some ethnic minor
ity groups. The findings suggest that addressing the problem of access
to care through an exclusive focus on the uninsured, especially throu
gh public programs, could leave significant residual problems for seve
ral segments in American society.
