Inequity in access to cancer care: a review of the Canadian literature.

Despite the policy and research attention on ensuring equitable access--equal access for equal need--to health care, research continues to identify inequities in access to cancer services. We conducted a literature review to identify the current state of knowledge about inequity in access to cancer health services in Canada in terms of the continuum of care, disease sites, and dimensions of inequity (e.g., income). We searched MEDLINE, CINAHL, and Embase for studies published between 1990 and 2009. We retrieved 51 studies, which examine inequity in access to cancer services from screening to end-of-life care, for multiple cancer types, and a variety of socioeconomic, geographic, and demographic factors that may cause concern for inequity in Canada. This review demonstrates that income has the most consistent influence on inequity in access to screening, while age and geography are most influential for treatment services and end-of-life care, even after adjusting for patient need. Our review also reports on methods used in the literature and new techniques to explore. Equitable access to cancer care is vitally important in all health systems. Obtaining information on the current status of inequities in access to cancer care is a critical first step toward action.
