Introduction
    This concept defines dialysis and describes how the start and end (exit) of this treatment are defined in the Care of Manitobans Living with Chronic Kidney Disease deliverable by Chartier et al. (2015). This includes the age groups applied, the data sources for this definition, the code values and conditions identifying dialysis treatment, and any additional conditions / restrictions that are applied.

    Dialysis is defined as a treatment for people in the end stage of chronic renal insufficiency (kidney failure). This treatment cleans the blood and removes wastes and excess water from the body (Martens et al. 2010).
