Disability in two health care systems: access, quality, satisfaction, and physician contacts among working-age Canadians and Americans with disabilities.

BACKGROUND: An overarching question in health policy concerns whether the current mix of public and private health coverage in the United States can be, in one way or another, expanded to include all persons as it does in Canada. As typically high-end consumers of health care services, people with disabilities are key stakeholders to consider in this debate. The risk is that ways to cover more persons may be found only by sacrificing the quantity or quality of care on which people with disabilities so frequently depend. Yet, despite the many comparisons made of Canadian and U.S. health care, few focus directly on the needs of people with disabilities or the uninsured among them in the United States. This research is intended to address these gaps. Given this background, we compare the health care experiences of working-age uninsured and insured Americans with Canadian individuals (all of whom, insured) with a special focus on disability. Two questions for research guide our inquiry: (1) On the basis of disability severity level and health insurance status, are there differences in self-reported measures of access, utilization, satisfaction with, or quality of health care services within or between the United States and Canada? (2) After controlling covariates, when examining each level of disability severity, are there any significant differences in these measures of access, utilization, satisfaction, or quality between U.S. insured and Canadian persons?
METHODS: Cross-sectional data from the Joint Canada/United States Survey of Health (JCUSH) are analyzed with particular attention to disability severity level (none, nonsevere, or severe) among three analytic groups of working age residents (insured Americans, uninsured Americans, and Canadians). Differences in three measures of access, one measure of satisfaction with care, one quality of care measure, and two varieties of physician contacts are compared. Multivariate methods are then used to compare the healthcare experiences of insured U.S. and Canadian persons on the basis of disability level while controlling covariates.
RESULTS: In covariate-controlled comparisons of insured Americans and Canadians, we find that people with disabilities report higher levels of unmet need than do their counterparts without disabilities, with no difference in this result between the nations. Our findings on access to medications and satisfaction with care among people with disabilities are similar, suggesting worse outcomes for people with disabilities, but few differences between insured U.S. and Canadian individuals. Generally, we find higher percentages who report having a regular physician, and higher contact rates with physicians among people with disabilities than among people without them in both countries. We find no evidence that total physician contacts are restricted in Canada relative to insured Americans at any of the disability levels. Yet we do find that quality ratings are lower among Canadian respondents than among insured Americans. However, bivariate estimates on access, satisfaction, quality, and physician contacts reveal particularly poor outcomes for uninsured persons with severe disabilities in the United States. For example, almost 40% do not report having a regular physician, 65% report that they need at least one medication that they cannot afford, 45% are not satisfied with the way their care is provided, 40% rate the overall quality of their care as fair or poor, and significant reductions in contacts with two types of physicians are evident within this group as well.
CONCLUSION: Based on these results, we find evidence of disparities in health care on the basis of disability in both Canada and the United States. However, despite the fact that Canada makes health insurance coverage available to all residents, we find few significant reductions in access, satisfaction or physician contacts among Canadians with disabilities relative to their insured American counterparts. These results place a spotlight on the experiences of uninsured persons with disabilities in America and suggest further avenues for research.
