There are some, but you'd be hard pressed to find any information about it online.
I'm unsure as to how the planned reforms will affect the welsh NHS, as health is a devolved power meaning the welsh assembly is in charge of it.
If you're asking this as interview prep I'd suggest the only thing you need to be aware of is that the NHS in wales is the responsibility of the welsh government, not westminster, which I suppose means the NHS in the two countires has different priorities as I should imagine prevelances of certain diseases varies due to socio-economic and geographical factors.
