It's a challenging question to ask overall. The data lend themselves to some aspects of it. For a number of years now, we have routinely indicated readmission rates for certain procedures—stroke and cardiac, for example. In a recent analysis we looked at readmission rates for hip and knee replacements, so we can see what the circumstances are in these cases. But that's not the only outcome. You would want to know how people are doing at home on an ongoing basis. But there are some points of analysis, like readmissions, that try to get at the question of outcomes.
