Cost-Containment, Medical
Technology and Access to Care: A
Comparative Analysis of Health Policy
in the United States, the United
Kingdom And Canada
Emily Adrion

Health System Structure
• Goals: Universal and equal
access, cost-containment,
efficiency.
• Financing: determines the
budget constraint and the
resource distribution/
allocation within the system.
• All industrialized nations,
excluding the U.S., have
national health services or
compulsory insurance
coverage.
Purpose of Research
• Exploding costs have been a major issue faced by
U.S. health policy makers
• Overuse of new medical technology is often cited as
one of the primary factors responsible for cost
growth.
• Have the more stringent cost-containment
strategies of nations with lower per-capita
spending inhibited the introduction and diffusion
of new medical technology?
• Greater control of costs neither limits the
introduction of medical technology nor results
in lower health outcomes.
Health Care in the United States
• Private health
insurance
• Traditional
Insurance
• Managed Care:
HMOs; PPOs
• Medicare, Medicaid
• 16% of the U.S.
population remains
uninsured (44 million
Americans)
Why the U.S. system suffers from
inefficiency and rising costs
• Market failures of health care:
• Information failures - Gov’t regulation
• Uncertainty- health insurance
• Problems with health insurance:
• Risk pooling => gaps in coverage
• Moral Hazard=> exploding costs
– The third party payment problem
• Managed Care as a Solution:
• LT effects on cost growth?
• Slower diffusion of new technology?
– RAND study (1981)
The Third Party Payment
Problem and Health Insurance
Traditional health insurance and the consumption of
health care in the United States
Canada: National Health
Insurance
• Universal coverage
• Single-payer plan financed through general
taxation
• Reimbursement: global budgets to hospitals;
negotiated fee-for-service to physicians
• Private production of health services
• With virtually no role for the market to set prices,
health care expenditure growth becomes almost
entirely a political decision made independently in
each province.
United Kingdom: National Health
Service
• Model of socialized health care
• Nearly universal coverage: small market for
private health insurance
• Single-payer plan financed through general
taxation
• Reimbursement: global budgets to hospitals;
Salaries and per-patient payments to physicians
• Public production of health services
Prices and quantities in a
controlled market
The Supply and Demand for health care in the UK
Theory: Technological Change and
Health Care Cost Growth
• Health insurance and the
bias towards costincreasing technological
change
– The Goddeeris Model
• Diffusion of new medical
technology
– Impact of regulation
and cost control
– Baker and Spetz
(1997)
Analysis: Overview of the Concepts
and Statistics
• Basic concepts:
• health vs. health care
• Outcome benefits vs. utility
benefits
• Statistical problems:
• Data not available for every
year for every country
• For many variables no data
could be found
• Differences in definitions of
variables
Regression Analysis
Quality of Health Care= f(total HC, R&D,
age, income, lifestyle, tech access)

Conclusions
• Theory: high costs and worse outcomes of US
system may be the result of insurance
• Without adequate control over total spending or total
quantity supplied the system may have inefficient
levels of cost-increasing technologies
• The raw data suggests the US may have inefficient
levels of high tech equipment (CT scanners, MRIs)
• Equally troublesome is that higher spending
has not resulted in greater health outcomes
• However, the effects of R&D are long term
• Outcome vs. Utility Benefits
Ways Forward
• Premium regulation
• Development of
standardized treatment
guidelines and protocols
• Medical Technology
Assessment
• To ensure costeffectiveness, safety
and efficacy of medical
innovations
