Oh how complicated this system seems to us Brits.Every one in the UK has one doctor called a General Practitioner,or family doctor he sees you about anything that is wrong with you be it surgical,medical etc.He sends you to the hospital if he thinks it is necessary to see an appropriately qualified specialist.Rob saw a Head and Neck consultant(i think you call then attendings but not sure) for all his treatment until radiotherapy was required .Then he was handed over to the Oncology Department in the cancer centre.The structure is Consultant,(Attending) Registrar(Chief Resident)House Officer (Resident)If Rob is poorly,or needs anything ,we tell the radiographer who bleeps the Doctor (usually the registrar),who comes down to radiotherapy and sees us and writes up any meds Rob needs for whatever the problem.We are seen every seven days by the doctor and dietician as a routine and if he is ill i take him to radiotherapy and they get a doctor.On top of all this a copy of everything done at the hospital is sent to our GP so he is on board if we have to call him out.It must be a desparate situation not knowing who to ask for what ,i hope it i resolved for you.
