NICE guidance applies in England, and Wales and Northern Ireland usually adopt it. Scotland has its own bodies instead, SIGN and Healthcare Improvement Scotland, so advice that quotes NICE may not describe how things work there.
Guidance is not law, and services can depart from it. It still gives you a clear, respected description of what good care looks like, which is useful when you are asking why something has not been offered.
Across the UK
- SIGN guidelines : Scotland uses SIGN guidelines and Healthcare Improvement Scotland rather than NICE, so NHS advice that quotes NICE may not apply there.
