As a part-time , I am part of an ambulance crew which takes very chronically-ill people home from a number of hospitals. Some hospitals are very good at advising patient carers about what's available but some are not and you have to be assertive about it, preferably some days in advance if discharge.
Some hospitals, of course, discharge at very short notice and, as an ambulance crew, we do our best to help a partner, relative or carer access services, public and private. Just think ahead as far as you can.
