Objective: Several studies have demonstrated increased postoperative mortality rates in patients on chronic hemodialysis compared with non-dialyzed patients. However, limited studies have examined factors that may contribute to postoperative mortality.
Methods: In this retrospective cohort study, data were collected from 9,140 dialysis and 45,725 non-dialysis patients undergoing surgery between 2007 to 2009 from Taiwan's National Health Insurance Registry Database.
