New nursing levels guidance examined in Wales
Draft NHS guidance which says patients could be at risk if nurses have to care for more than eight people is to be examined by the Welsh government.
The National Institute for Health and Care Excellence (NICE) said hospitals in England should be wary about that workload being exceeded.
The guidelines do not apply to Wales, but the Welsh government says it will "look at what they are proposing".
Wales has seen the largest rise of nurses in the UK since 1999, it said.
Prof Ceri Phillips, health economist at Swansea University, welcomed the discussion. BBC Wales' Rebecca John asked him if the targets were achievable.
