"Lack of communication between staff"

My mother in law has just been a patient in this hospital following her recent surgery at St. Georges and then at Frimley Park in cardiac care. The lack of any communication between staff is appalling. After twelve days of being there only yesterday when they neede to get in touch with us did they realise they had no contact phone number for any family member. It is a shame that this situation can happen and had caused considerable stress to my mother in law.
