Back to Chapter 9 Practice Questions
1. What barriers did traditional fee-for-service medicine
create to restrain the growth of HMOs prior to 1973?
denying hospital privileges to HMO physicians.
p. 208
excluding HMO physicians from medical societies.
pushing for state legislation that forced HMOs
to accept any physician (any willing provider), requiring HMOs to be nonprofit,
or prohibiting HMOs from advertising (which favors the established providers
at the expense of the new provider).
discriminatory use of Certificates of Need against
HMO hospitals
2. What legislative, economic, and judicial developments
occurred from 1975 to 1985 that encouraged the growth of HMOs and competition
in the health care markets? When did HMOs experience their greatest
growth spurt?
Growth of HMOs: mainly due to the HMO Act of
1973. Also, revision of Public Law 93-641 in 1979, which reduced
state legislatures' abilities to restrict HMOs. p. 210
Recession of 1981 forced employers to be more
cost conscious. Reduced marginal tax rates reduced the attractiveness
of fringe benefits vs. take-home pay.
Supreme Court's 1982 decision that medicine could
be subject to anti-trust laws p. 214
3. How are HMOs similar to PPOs? How do they differ?
Similarities: restricted panel of providers,
incentive for patient to use less treatment.
Differences: HMPs are capitated, PPOs are fee-for-service.
Traditional HMOs have a closed panel of providers, PPOs try to get as many
providers as possible to sign up with them. p. 218
4. Regarding the quality of care provided by HMOs and fee-for-service
systems, how did John Ware's 1996 study force people to reinterpret Miller
and Luft's 1994 study?
Miller and Luft's meta-analysis said that the
average person in an HMO does as well or better than the average person
in fee-for-service. Ware found that the benefits are not uniform
across all patients. Specifically, Ware found that the poor and the
elderly did better under fee-for-service.
5. "HMOs are losing their competitive edge. Fee-for-service
costs are almost the same as HMOs' costs." Would Wickizer and Feldstein
agree that HMOs are losing their impact? How would they interpret
this finding?
No, they would not agree. They would say
that HMOs have a major effect on the markets, but we do not see a major
price difference between HMOs and fee-for-service because the market has
become very competitive. There is a "spill-over" effect of lower
HMO prices on fee-for-service prices. They noticed that when HMOs
are present in a market, prices are lower.
(Don't ignore the 1984 RAND study.)
