The premises in which the simple self-dialysis unit or the assisted self-dialysis unit is installed may be shared by these units, a medical dialysis unit or a haemodialysis centre. In this case, the patients treated simultaneously are dialysed in separate rooms, depending on whether simple self-dialysis, assisted self-dialysis or medicalised dialysis is involved. However, it is possible to treat a group of haemodialysis patients successively in the same room in a haemodialysis centre, in a medical dialysis unit or in an assisted self-dialysis unit.
When the haemodialysis room is shared by assisted self-dialysis patients, it is impossible to carry out more than two haemodialysis sessions per day on the same station. A room is always reserved for patients treated in a simple self-dialysis unit.
