A comprehensive evaluation of hemodialysis is generally recommended 3 times a week for 4 hours each time. If less than this number, the treatment may be less effective and prone to complications. Some of the new treatment methods, such as dialysis 3 times a week for 5-7 hours each time, or even night dialysis, may have outstanding efficacy in some aspects, but there are also problems of cost effectiveness and patient compliance. In order to ensure the quality and safety of hemodialysis and the proper management of emergency situations during the dialysis process, patients must undergo hemodialysis in the hospital.
