Shall I go first? Is that okay? Yes, I think that's obviously a really, really important question. Workforce is the single biggest issue, I think, holding back endoscopy services and cancer services more broadly. We know that workforce shortages, again, are not just a Welsh issue. So, it's reported across the UK that workforce issues within endoscopy are probably the biggest challenge. We don't know, however, what it looks like in terms of capacity in numbers and data in Wales, so I don't have—maybe it is collected, and not publicly—but we don't know how many endoscopists we have, where they are, where shortages are, those sorts of basic bits of data are really, really, challenging to have. There is obviously, of course, anecdotally, regional variation. Again, I don't have the data to back up where that is, but that is a really, really important part of the puzzle to understand how to address workforce shortages. We know that it is capacity in the system that is driving these long waits.
In terms of your question on solutions, yes, I'd definitely come back to community diagnostic hubs. In the long term, it is doing really proper data collection, recording that and sharing that publicly. In thinking about what's making people leave the service, what's affecting staff retention and well-being, and all of that, I know we've just had a workforce plan out from Welsh Government yesterday, I believe, so there will be some really positive things in there, but in the shorter term, I think it's about maximising retention. So, it feels basic but it's things like thinking about flexible working and part-time working—how can the NHS support particularly people who are thinking about retirement, but lots of us are thinking about flexible working, particularly post pandemic. And also, skills mix approaches. So, thinking about how we can use non-medical endoscopists to support endoscopy services, and I know that it's something that Health Education and Improvement Wales are really interested in as well.
The other part of the picture, as you alluded to, is the innovations piece. So, it's new things, new ways of doing things that will help the burden, I guess, on capacity and demand. So, yes, we absolutely think community diagnostic hubs, which obviously include endoscopy services, are a really fantastic innovation that we think Wales would really benefit from, and I understand that it is going to be part of the cancer improvement plan that, again, was published this week. Whereas the difference between regional diagnostic hubs [Correction: 'rapid diagnostic clinics'] is around endoscopy services being part of that. So, yes, we think that more can come out into the community—that can only be a positive thing.
There are other innovations such as colon capsule endoscopy, cytosponge, transnasal endoscopy that, again, can be actually less invasive and better for patients in lots of ways, and also, again, remove some of that burden from more traditional, I guess, endoscopy services.
