The present study examined population level data on unmet needs for adults with physical, sensory and cognitive disabilities, using the National Population Health Survey. The study revealed that disabled adults (aged 20-64) reported more than three times as many unmet health care needs as their non-disabled counterparts. Even after controlling for the effects of age, gender and poor health, disability had a significant effect on the perception of unmet needs, particularly disabilities associated with pain, hearing impairment and emotional problems. The greatest deterrent to receiving needed services among individuals with disabilities was cost. Despite being publicly funded and thereby presumably equally accessible to all, the health care system in Canada fails to meet the needs of some of its most vulnerable constituents--adults with disabilities.
