Geographical disparities in gastroenterologists and transient elastography across Canada

Abstract

Background: In the next decade, the incidence and prevalence of advanced liver disease are expected to increase across Canada. However, little is known about the country’s resources for monitoring patients requiring specialized care. A resource assessment was conducted to evaluate regional disparities of specialists and transient elastography machines across Canada. Methods: Demographic data on licenced gastroenterologists were obtained from Scott’s Medical Directory as of October 2022. The primary location of each specialist was linked to 2016 Statistics Canada to obtain the population size and density of provinces/territories and census division (CD). Results were summarized per 100,000 persons. CDs were classified as resource scare or approaching resource scarcity. A list of transient elastography (TE) was provided by KNS Canada Inc. and summarized per 1,000,000 persons by province. Results: Eight hundred fifty-three specialists were identified. Rates of gastroenterologists per 100,000 people ranged from 0 in the territories to 2.9 in Quebec. Half the provinces had fewer than 2.0 gastroenterologists per 100,000 persons. Gastroenterologists were concentrated in 24% (71/293) of the CDs across Canada. We identified resource-scarce CDs as areas with no gastroenterologists and in the highest tercile of population density, which accounted for 33% (1 of 3) in Prince Edward Island, 32% in Quebec, 25% in Ontario, 7% in British Columbia, and 4% in Manitoba. Only 94 TEs were identified nationwide. Conclusion: We found significant variation in liver-specific resources across Canada. Given the increasing number of people living with liver disease, policies must be implemented to address access to specialized care.
