The introduction of the new SC+ device during the COVID-19 pandemic has had a significant impact in supporting critically ill patients developing kidney failure. As a versatile and compact dialysis machine, the SC+ system provides a wide range of renal replacement therapy options for ICUs, dialysis clinics and patients’ own homes. In the near term, rapidly increasing the use of home haemodialysis will also be crucial to reduce the risk of COVID-19 in dialysis patients.
