cerabal palsy. He is in the hospital now with Merca (sp),kidney failure, pnemonuia. The doctor has run numerous test and has advised the family that he will not get better..My brother has always been his own POA.. The family has told him what the dr.has said and asked if he wants a feed tube put in and he advised no..The agency that has been taking care of him for the last 7 years has gone to the hospital and said that they want the family decision overturned and that they want a feed tube put in and dialysis on his kidneys...they are telling the hospital that my brother makes his own decisions and that they know this is what he would want..they want it done immediately and then for him to return to their facility for them to take care of him...they did this after we left the hosp tonight?? can they do this?? the dr. said we are next in line to make any decision for him if he cannot make them himself...any suggestions?
