I think it's safe to say we do have a fairly good idea of people who can't access medicines. It is people with lower income, and not having coverage is the most significant determinant of whether or not you are going to fill a prescription. In fact, a high-income person without insurance is more likely to not fill a prescription than a low-income person with insurance. This is a big issue.
I have a paper in the Canadian Medical Association Journal from this year, which the analysts might be interested in seeing, about the differences in volume in therapy purchased by comparable countries. It's not that big. The difference is in prices and the difference is in product selection decisions. It's about whether lower-cost options are being used more often versus higher-cost ones.
