Maybe I'll answer first. I think there's always need for education, both intra-professional and interprofessional. Education in and of itself can be a relatively passive strategy. It's important, but it needs to be coupled with other things. What's worked really well—and Andrew can speak to this, I know—in the hospital care environment is direct audit and feedback, and physicians' prescribing practices being compared with those of their peers.
I've lived and worked in that scenario as well, and I feel that it has met with quite a bit of success. I think the way we educate and how we actively provide feedback becomes a little bit more salient than sort of more passive group education, but it's important.
