An apparatus, a process and a system for monitoring a plurality of patients (P) affected by kidney failure over a time frame (T) are disclosed. The system includes blood treatment units, laboratory storage units, at least one hub module, and client units. The system collects values (VM) of a plurality of session parameters, set values (VS) of a plurality of prescription parameters, values (VL) of a plurality of laboratory parameters and the hub module stores values (KPVi) of selected parameters (KPi) which are a subclass of the collected values (VM, VS, VL) and which are transferred to the client units. Each client unit may define, for each of said patients, a number of indicators (IDk) based on the values (KPVi,k) taken by a respective subclass (KPi,k) of said selected parameters (KPi) and to operate the respective display according to various display modes.
