pixie, in good care, whatever you call it, food and drink is not withheld.
if you google Liverpool care pathway documentation, you should find one that you can read. NOWHERE does it advocate withholding food or drink. The medications that are stopped are the unnecessary ones. Where helpful ones are still given, a drip is set up so that they can be continue to be given even after the patient will not or cannot take them orally. They can also be given fluid through a drip (specifically mentioned) but if eg the heart or kidneys are failing then that fluid will make the patient less comfortable as it will sit in the tissue, causing swelling and breathlessness. In this case, the mouth should be moistened as often as the patient appears to need it. If the patient wants either food or drink thatey should always always be given it.
Whatever the new setup is called, it will still have to address the same issues and best practice which the actual pathway does cover, will remain unchanged. Please please go and read what the actual document says and not what the newspapers say that it says.
I agree about discussion and discussing DNR. My husband was fortunate in having very good end of life care, the only problem was a lack of resource.
