Wp. Welch et al., A DETAILED COMPARISON OF PHYSICIAN SERVICES FOR THE ELDERLY IN THE UNITED-STATES AND CANADA, JAMA, the journal of the American Medical Association, 275(18), 1996, pp. 1410-1416
Objective.-To assess the relative volume and price of physician servic
es in Canada and the United States. Design.-A comparative analysis of
1992 claims data from Canadian provincial ministries of health and fro
m the US Health Care Financing Administration. Patients.-All elderly i
ndividuals in the 3 largest Canadian provinces, Ontario, Quebec, and B
ritish Columbia, and a 1% random sample of US elderly Medicare benefic
iaries not enrolled in health maintenance organizations. Main Outcome
Measure.-The volume of physician services measured in terms of the rel
ative value units used in the Medicare fee schedule to calculate payme
nts, with services disaggregated into clinically meaningful categories
. Results.-Canadian elderly receive a higher volume of physician servi
ces than US elderly. Because the provinces examined paid a much lower
price per service, Canada had overall lower expenditures per elderly p
erson than the United States, Canadian elderly received 44% more evalu
ation and management services, but 25% fewer procedures. Canada has a
disproportionately lower volume of procedures for which there is low c
linical consensus as to when they are indicated. Such procedures inclu
de cataract extractions and knee replacements. Conclusion.-The lower p
rices for physician services in Canada permit Canadian elderly to rece
ive a higher volume of evaluation and management services with lower e
xpenditures than US elderly. Expenditures for procedural services, on
the other hand, are constrained by both price and volume. These differ
ences in the volume of physician services may be the result of differe
nces in facility and physician supply.
