I'll pick up the first point about variation. So, we have the sharing of information across the NHS in Wales and, indeed, outside. So, in terms of that clinical variation and differences in terms of the number of people seen in a theatre session, for example, with the getting-it right-the-first-time team, which is working with the NHS, some of that is about cultural change, about working with clinicians and getting everyone to see how you can do things differently. So, those things take time, but those structures are there.
We have the great work the financial delivery unit have done around benchmarking, which we can all access via the vault. Those feed into our plans. So, when we look at our savings opportunities for the year, that variation, that benchmark will inform where we target. We also are working very closely on value-based healthcare and trying to stitch some of those things together so that, for example, we're looking at a scheme for next year, funded via value-based healthcare, which is working with housing associations to see if we can intervene early with people who are tenants where we're starting to see—. The housing associations know them best and know that they're starting to show distress. So, can we start to intervene early and deliver better value by secondary prevention, effectively?
In terms of the estates element, we are facing quite a difficult scenario, because inflationary pressures within that environment and the capital environment have been even more marked than in other areas. So, we are seeing huge increases in cost when we go to the market to test the market for schemes, but also, on occasion, we're not seeing people respond. So, firms do not want to take on the work, because I presume they're just trying to batten down the hatches, so to speak, and keep working. So, we have got schemes around, as you say, LED lighting, energy efficiency, but they are incidental to the real challenge of older hospital premises and updating them. The thing that we have to remember is it's not always about the scheme that's about a new area or something different; it's about some of our core infrastructure. Is the electrical infrastructure up to standard? Can we even put in electrical car charging points based on the current scenario? Those are expensive schemes. We've spent, at the Royal Glamorgan Hospital over the last couple of years, around £2 million just to upgrade the electrical infrastructure. That's just about standing still, really, and those costs are rising all the time. So, it's very much in our focus, but we are limited by the amount of capital available. We know that that's a real challenge for Welsh Government and for health boards as we move into the next few years, so we do need to be really targeted in terms of how we do that.
