To start with, I'd say that the figure of one in 12 Canadians having a rare disease emphasizes maybe the wrong message that the Canadian organization for rare diseases is giving. It seems to imply that rarity isn't very rare and that therefore the impact of making decisions to fund drugs for rare disease which don't increase the overall health of the population might be much bigger than we actually think it is.
Part of the problem there is, what is the definition of “rare”? When we think of rare, we think of diseases for maybe one in 100,000 Canadians, or one in 50,000 Canadians or even one in a million Canadians. Part of the problem is that CORD uses a definition of rarity which I think is maybe one in 20,000—I can't remember—but it's not what people think of as rare.
We really need to realize that rarity is not a binomial issue. It's not “your disease is rare” or “your disease is not rare”. There are different levels of rarity. I can very much understand that a lot of us are thinking about those ultra-rare diseases—those one in 100,000 and one in 200,000 individuals—and that's where I think Canadians might think that there's a value in having some separate process for those ultra-rare conditions.
I think the definition that CORD uses in throwing around those figures like one in 12 Canadians having a rare disease—or one in 10 Canadians, they've even said—is really, really unhelpful to this debate, because we're not really talking about having a disease for one in 2,000 or one in 5,000 Canadians. We're really talking about those ultra-rare conditions that maybe 100 Canadians have or that 50 Canadians or even 10 Canadians have. That's the dialogue that I think we're supposed to be having here, and it's not the idea of the one in 12 figure, which really is unhelpful.
To be honest, if one in 12 Canadians has a rare disease, then we can't treat rarity as special, because almost everybody has a rare disease in those contexts. I think this definition that CORD uses is really counterproductive to this argument.
If we can focus on those ultra-rare conditions, then maybe we might think that Canadian values should reflect some special process or some special funding envelope for that, but that's for you individuals to decide. Clearly, if you've left it up to the general public, the general public doesn't think we should have that special process or special funding envelope.
