Language: the ignored determinant of health.

Canada is one of the most multicultural countries in the world, with growing numbers of families who do not speak English or French as a first language. However, providing language-concordant services for patients with non-official language preference (NOLP) is not a standardized or measured component of our healthcare system, reflecting the historical marginalization of minority groups in our society. Existing evidence from other countries demonstrates the importance of language as a social determinant of health, and illustrates improved healthcare outcomes for patients with NOLP with the use of medical interpretation. This commentary proposes that a change in our approach to patients with NOLP needs to be accomplished through concerted efforts at the policy, research, and institutional levels in healthcare.
