That's a great question. We have just completed the Rx 2000 rollout of what we consider to be our mental health program, and we're just initiating a validation of that model to look at a variety of different outcome measures.
The other thing we're looking at doing is instituting an outcome measures tool to look at how our patients are responding to different levels of treatment. If patients aren't responding well, we can look back at the case, we can find out what more we can do to help them, and we can reinvest treatments in that person. Or if somebody is doing better than expected and they don't need as much therapy, we can redirect those resources to people who may need a little bit more. We are absolutely looking at many different ways to validate what we do and make sure that it's appropriate.
