Objective: Methods: - TRIAGE: we call all HD patients to inquire about symptoms or potential exposure (Covid- suspected or positive) - access prohibited to drivers and visitors - Re-organized waiting room, maintaining a distance, staggered entry - HD patients wear a mask from the moment they leave their house, until they return home - Patients were instructed to measure the temperature at home twice a day and to call the dialysis unit if they develop symptoms at home (es fever>37C°) before their scheduled treatment. Patients without severe symptoms be transported in a private vehicle without other patients, and be dialyzed in isolation room. - new 4 isolation room in Covid's ward, 1 for suspected patient in Geriatric's ward - the dialysis unit was equipped with 3 mobile single patient reverse osmosis, 2 machines for standard dialysis and 1 machine for CRRT. - the dialysis unit staff do test for  SARS.COV-2 Methods: Outcome: - Incidente rate of COVID in HD patients: 4 cases in 51 HD patients - Incidente rate of COVID in dialysis unit staff: none Results: BEST PRACTISES, BEST DIALYSIS? Conclusions: Objective: In March 2020, who announces COVID-19 outbreak a pandemic.  Elderly HD patients has a high infection because of disability, comorbility, social state and travels to and from hospital. The presentation of Covid-19 may be atipical in these patients. It was necessary to redefine the management of dialysis unit in order to avoid the spread infection in the HD patients, to treat Covid-19 whit CKD and Covid-19 AKI that need RRT. Since March 2020, we adopted the first protocol from Lombardia and Italian Society of Nephrology called "Protocollo coronavirus e dialisi". We updated the protocol whit check list and procedures based on the new scientifics evidence and the pandemic trend and re-training the staff.   Methods: Methods: - TRIAGE: we call all HD patients to inquire about symptoms or potential exposure (Covid- suspected or positive) - access prohibited to drivers and visitors - Re-organized waiting room, maintaining a distance, staggered entry - HD patients wear a mask from the moment they leave their house, until they return home - Patients were instructed to measure the temperature at home twice a day and to call the dialysis unit if they develop symptoms at home (es fever>37C°) before their scheduled treatment.
