First of all, I'll make a disclosure. I am not an expert in registries, but I think there's lots of published literature on them. I think what I would advocate for is developing a steering committee that makes those tough choices about registries, because I heard the ideals about the registries and those seemed to make a lot of sense, and that's what's published.
I think the Netherlands is one of the big four in the world. The U.K., Netherlands, Australia and the U.S. are the four models of registries. I think the first thing we should do if we go this route is to make ours better. Draw on the experiences of other registries and make it even better.
One of the things that is important to the registry is to get the uptake of the surgeons entering the data, because they have to do all the data entry. If you have it on a smartphone, have an app, they would be mandated, as my colleague said, to make the registration. You have to have a stick to make everybody comply, but I think it's very important to come up with a very definite plan.
