Father, late 70's, has advanced dementia, fractured hip and having been in hospital for 4 weeks, 3 post op they have decided he is likely to never walk again. Physio has been almost non-existent. Mother cannot cope with him at home and hospital say they will discharge to an NHS nursing facility (not a covalescence home as no propspect of improvement). I am confused as to what this is exactly - and is there a cost implication here?
