Many who are uninsured may receive poorer quality health care simply because they do not carry insurance. According to the Employee Benefit Re-search Institute (EBRI) in its 2001 Health Confidence Survey, more than two-thirds of uninsured Americans are concerned that they will not get top quality care should they need medical treatment. Moreover, they worry about how they would pay for prescription medication (which can be an enormous expense, especially for a chronic condition) if they needed it.
