If you have been treated previously at a hospital, you can request that you be transported there. If you or a carer can call ahead to the ED and ask to speak to a Doctor and advise them you are being transported. this will help you on arrival. They will be ready for you. However if you re not stable you will be transported to the closest hospital.
