Sorry; I might have gotten a bit off track.
I think pharmacists can certainly help in that way to make sure that use is appropriate.
I think your other question was around general approaches to improving prescribing. I think the electronic medical records with cues embedded in there could go a great way to assisting in prescribing. They could put up red flags when things don't match up, when things don't look right. I'm not a technical person, but I've seen examples of some amazing things that can happen.
There are examples of good tools out there to put in the hands of prescribers, which might help them to do a better job.
