That's right. It's more difficult for the physician to respond because the physician doesn't actually witness that, as opposed to a hospital setting. It's fairly clear when dialysis takes 14 hours a week and whether it's more than three times a week. That becomes very clear.
In the case of diabetes, it's much more complicated, so that's why that back-and-forth interaction with the doctors happens much more. You add to that the complexity of the therapy, which is becoming modernized and easier to manage in some cases, but not all.That's why those clarification letters are required and why we continually evolve with the communications to make sure that we are getting the specifics of that individual.
