The practice of pathology in Canada: decreasing pathologist supply and uncertain outcomes.
BACKGROUND
Pathology organizations in the United States are preparing for a new era of health care reform. Trends in the supply of pathologists in Canada's managed care system may provide some useful insights in any analysis and projection of future pathologist needs in the United States.


OBJECTIVE
In this study, population-based Canadian databases were used to devise a parameter for physician supply, cancer cases per physician. The trend in this supply parameter for pathologists was compared to that for radiation oncologists.


METHODS
The number of Canadian pathologists and radiation oncologists and the annual number of new cancer cases in each of 2 years, 1999 and 2009, were extracted from reliable databases. Cancer cases per pathologist and oncologist were calculated, and relative trends in supply of physicians in both specialties were identified.


RESULTS
The annual number of new cancer cases increased from 129,300 to 171,000 from 1999 to 2009. The absolute numbers of both pathologists and oncologists also increased in this time period. However, while the increase in the number of radiation oncologists led to an 8.2% decrease in cancer cases per radiation oncologist, the modest increase in the number of pathologists led to an increase of 17.1% in cancer cases per pathologist.


CONCLUSIONS
There is a trend toward a decreasing supply of Canadian pathologists relative to that of cancer demands. This finding confirms an earlier population-based study showing a decreased supply relative to population and number of clinical physicians. It is uncertain whether this decreased supply is a result of appropriate application of new, efficient methods or whether health care has been rationed or adversely impacted. Outcome measures to monitor Canadian pathology practice quality are clearly needed.
