Thank you. Do you want me to start? Then, Ilona, I'm sure you'll have a view. I think it's an important question that's going to become increasingly important, given that we absolutely have to shift to prevention at some pace. Similar to the conversation that we've been having so far, obviously the Welsh Government's role around setting strategy and plans and priorities is really key.
The Cabinet Secretary did a statement around prevention, which obviously included a lung cancer screening programme, and I would say the conversations, from a political and an official discussion, firstly, around prevention, are far more prolific than they have been, so I think that's really positive. As the committee may be aware, the Welsh Government have recently set up the preventing ill health group, which the chief medical officer, who I'm not sure if you've met yet, is chairing, and will bring an energy to that. We have quite strong hope that that will really accelerate a focus around prevention. So, in the same way as everything else, obviously the Welsh Government's focus in setting priorities is key.
Prevention isn't just about health, though, as we know, so if we're really going to tackle prevention, it's about all of the wider determinants. The NHS is often after the fact, and if we can shift that whole focus, which is kind of going into hospitals, into that whole focus about creating healthy communities, we'd be having a different conversation about the NHS. So, Government's role in the implementation of the Well-being of Future Generations (Wales) Act 2015 in ensuring that there is health in all policies and all policies in health is absolutely fundamental. We work with education, with economy, with trade, with climate, because it is all about creating that healthy environment. I see Government's role, similarly, about having that cross-Government focus for a healthy society, which is about a preventative-focused society.
Just to expand on our role, obviously we have a number of statutory functions. At the heart of our role is prevention, because of creating a healthy society. We've talked about our screening role, but we also do a huge amount that I'm sure Ilona will want to talk about around health improvement, working with schools, working with the NHS, working with local authorities, third sector, in a purposeful focus around the evidence-based interventions that will have the biggest return on investment and biggest outcome. We published a report a couple of months ago called 'Investing in a Healthier Wales: prioritising prevention', which was a life-course approach to the prevention interventions, children and early years, adults and healthy ageing, but those that will yield the biggest return on investment.
Our role is also about providing advice to Government, to partners, about, 'This is where the biggest bang for buck is that will have the biggest impact on outcomes for the population'. Obviously, we survey the population, we monitor the conditions right across Wales, and we also do a lot of support, convening, resources, guidance, tools. We've talked about health equity previously as well. We see ourselves as providing solutions to help people implement those interventions. We also provide a lot of support to Government, did a lot of work with them around food regulations, the legislative drivers for public health, for prevention. We can't legislate for everything, but there are some really key drivers. So, we have, I would say, an expansive role across all sectors, but it's about prioritising the things that will make the biggest difference.
