Thanks, Chair. The starting point for me on this has to be the rapid change over my career that I've seen in the epidemiology of disease—in the UK generally, but in Wales in particular, of course. When I first qualified in medicine, a lot of the focus was still on infectious diseases, but, of course, non-communicable diseases were absolutely on the rise, and there were lots of investments in those areas of, often, long-term diseases, chronic diseases, if you will. But the biggest change, I suppose, in more recent times has been the move from a focus on single-disease issues—heart disease or lung disease—to recognising the fact that people suffer from more than one chronic condition, and the rise of multimorbidity, as we often call it. And that has gone hand in hand, of course, with the demographic transition, the demographic changes that we've seen in Wales, where we are, of course, an ageing population, we'd recognise that, and that brings all the problems of multimorbidity and having more than one disease.
When you ask me about the barriers, I think what I would start with is the way the workforce is shaped in the NHS, certainly in healthcare, less so on the social care side. But, on the health side, we have, for a generation now, been training people to be specialists and superspecialists, often, in conditions—and we do need specialist assessment and we do need superspecialist treatment occasionally—but that has been to the detriment, I believe, of general medical knowledge and general medical understanding. And, to really treat multimorbidity and multiple chronic conditions, especially in frail, elderly people, I think you need doctors, clinicians who have a broad understanding of a number of conditions, not just, not solely a detailed understanding of a single condition. So, there's something about how we build the effective workforce to deal with multimorbidity. That's about doctors, but it's not all about doctors; it's about the broader healthcare team around them and making sure that that's well organised and well developed.
There is something also about the way that we use our health system. Primary care, as I'm sure we all would recognise, is very significantly overloaded, and we need to think about how primary care can best meet the needs of people with multiple chronic conditions. Primary care is the place where most health service should be provided, but it's under significant stress—we may want to go in to some of that at some point, Chair.
On the secondary care side, of course we have a significant problem that our hospitals are overloaded, and they're not fit for purpose in terms of the ageing infrastructure that we have here in Wales and across the UK. There's clearly a need for significant capital investment to make those facilities fit for the future, and this is a time when it's very difficult for Government, I think, to attract capital investment. So, that's going to be a major challenge, going forward. I'll maybe stop there, because I'm sure there'll be areas that you'll want to delve into a bit more in detail, Chair.
