 I'm Andrew Crowder. I'm the head of programme of the Diabetic Retinopathy screening service in Wales. My interest here today is actually one of the presenters in the breakout sessions. Really what I wanted to do here was showcase what I think is a really good example of prudent healthcare within our service. So we're looking to roll out what's known as risk-based screening which has been developed in the UK. And we are leading the UK. We will be the first of the programmes in the UK to roll out out. And what I was looking to get over to people was just what value there was in that and particularly value in terms of prudent healthcare. I want to share that experience with people because I think there's a lot that people can learn from what we've done already. But more than that I want to inspire them as well to help them to be encouraged to get into this kind of thing. I mean we put a title of prudent healthcare around these kind of things. And sometimes people don't always know necessarily what that means but by enabling practical examples you can actually show them. And you can see the light up on their face and they think, ah, I understand where you're coming from. And actually we do that as well or that's something that we'd like to get into. So it's about really passing on our learning so far. But also to use the conference to network. You're always looking for encouragement to make sure that what you're doing is prudent so that it actually fits the agenda that you think it's fitting. But also other people will come along with ideas. We don't claim that we have all the ideas in the world and we've got it all right. So just talking with people today, several people have come to me and said, have you thought about this, have you thought about that? And the simple answer is maybe not as much as I first thought and I need to go away and think about that now.
