We keep having to cancel outpatient appointments like echocardiograms for my dad because he's just physically too frail to make it hospital. Just this morning I had to help him get up from the toilet because he couldn't stand. He clearly needs proper hospital admission where they can wheel him around in a bed and do all the tests they want to do to diagnose whatever he has. Should I just call the GP and explain the situation and they'll send an ambulance to take him in?
