The Prevalence of Chronic Pain in Canada

Abstract

Published population estimates of the prevalence of chronic pain have been highly variable due, in part, to differences in definitions and study methodologies. Designing health care delivery models that address chronic pain and reduce its impact, however, require accurate, up-to-date prevalence data. This article first reviews studies that examined the prevalence of chronic pain both internationally and in Canada. The ensuing sections describe a telephone-based survey of a well-defined population of adults using a detailed and sequential definition of chronic pain, and well-validated and reliable data collection tools for establishing the prevalence of chronic pain in Canada.
