"Care for my father in law"

I am absolutely appalled by the treatment of my 95 year old father in law. He has Parkinsons in his legs, liver disease and mostly low blood pressure. He has had many falls banging his head each time. In the early days he was admitted to hospital and even given time at Barton which allowed him to come home. Now he is in a pathetic state and has had 2 falls this week. He was admitted to hospital on my Husband's insistence glued up and then sent home the next day( without anybody informing his son), unable to even operate his walking frame because he is too doddery. His hair is matted and he looks so poorly that my daughter has stopped taking her daughters to visit him. This morning he has fallen again hitting his head on the toilet. First Call called the ambulance and they have refused to take him to hospital because they consider him not' bad enough'!! So he is waiting to be glued up again? I informed the doctor that unless something is done for him there is going to be a real mess for somebody to find. I wonder why he was not made comfortable in the beginning without spending NHS funds to leave him this way?
