UPDATE:
After making our concerns of her being discharged to early they moved her out and arranged 2 visits a day and some aids for the house. Unfortunately she has not improved to the degree that the doctor took some bloods and sent them off. Once They had been analyzed the GP surgery was closed so the results went to the out of hours who called for a paramedic to go to the house. She was taken to A&E and more bloods taken. She was then moved to the acute medical unit for monitoring and at 3am we were told it was best to go home and let her sleep. When we went back she was on full blood as they found all her levels were low and have been dropping for some weeks. I got a call from a consultant the next day asking me and my sister to met him at 10:00 to discuss his findings in the ward she has been moved to. Once there we found it was the Oncology ward. The consultant explained the results to date and prognosis and further tests that will confirm the progression.
If they would of been prepared to look a little further and listen to our concerns, I am sure it would not of changed the diagnosis but maybe would of made those few weeks at home less of a nightmare it had become for her!
