It is a massive question that we could probably discuss for the remainder of the day, so I will try and make my answer more succinct.
With the evaluation of services, you've got the Eye Care Wales Committee, which oversees the delivery of services. We are really fortunate that the contract introduced clinical services and it also introduced different aspects as well, and one of those was the quality in optometry. As part of the quality in optometry package, there are three service insights that are performed by the national clinical lead each year.
These service insights are mandatory for contractors to take part in, and they can cover all aspects of eye care delivery. They can cover the delivery of wider Welsh Government policy within primary care NHS optometry. For example, last year, we looked at the impact of environmental Welsh Government policy on primary eye care optometry.
We can also look specifically at the services being delivered, so we did a deeper dive into the smoking cessation practice of optometrists, because that was a new part; the prevention agenda is a huge new part of the optometry contract, so we took a deeper dive into how optometrists are approaching that. It is a new part of their practice.
We know, in Wales, not everybody is eligible for NHS eye care, so we know what we know about our NHS patients, but there is obviously a cohort of the population in Wales who don't access NHS eye care services. So, the insights give us an opportunity to review that as well.
We have the service insights and the content of those is agreed by NHS Wales and Welsh Government. We also have a massive amount of data that is reported across all five of the WGOS levels. That data is reported to health boards on a monthly basis, because at the end of the day, they're their services, they deliver their services, it is their data.
It was one of the things that we really took a lot of thought over in the design of the new pathways, particularly the WGOS 4 pathway. That's a pathway that will be most instrumental in moving patients out of secondary care into primary care, and in stopping patients going from primary care to secondary care. In doing this, we are not only looking at moving clinical care, but we have to move everything else that goes with that. So, the governance that exists in secondary care for our patients in Wales, we need to make sure that the equivalent governance exists in primary care.
We are familiar with waiting lists in secondary care. We don't just want to shift waiting lists from secondary care to primary care, but to ensure that we are not doing that, we need to collect the data to capture waiting lists, to understand capacity and resource, and how patients' needs are being met. We collect a huge amount of data, it's reported to health boards, and then we have oversight, as national clinical lead, from a national level. We can see what's going on. We have the advantage of being able to look at activity across different health boards, and if something is working very well in one health board, and maybe another health board isn't quite there, we can explore why.
One last bit. That data also then gives us the opportunity to identify areas where, maybe, more research is needed, because data gives part of a story, it doesn't give the whole story. So, we might identify an area where we think we need a deeper dive, which is maybe a research project, and we might do that, we might collaborate with academics to do that.
Then, the final part, which is really important to highlight, is that we collect, routinely, patient-reported experience measures across WGOS 1, 2 and 3, and we will introduce that into WGOS 4 and 5 as soon as we can. Again, it's tempting, isn't it, to look at the data, to look at the waiting lists, and for it all to be very quantitative and dry. Actually, what we are trying to do is to improve services for patients, and in doing that, make sure that the experience they have in accessing our services is as good as it can be. So, we are trying to bring the patient voice, the patient representative, into what we do as well.
