The Royal College of Nursing said NHS guidance on treating acute kidney injury was "important and timely".
Dr Peter Carter, Chief Executive & General Secretary of the RCN, said:
This guidance should help doctors and nurses to spot those patients who are at risk and be confident in monitoring and treating them.
Specialist nurses are already making a considerable difference in this field and their expertise has been crucial to this guidance.
This is an area of medicine where many lives could be saved if the level of understanding is the same among staff in all settings, and the NHS as a whole should act on this guidance as a matter of urgency.
