The kidney transplant rate is outpaced by the rate of readmission for complications.

Hospital readmissions experienced by kidney transplant recipients may be secondary to a range of conditions, including infections and rejection episodes. The objective was to identify trends in patients with kidney transplant complications, in regard to hospital discharges, ED visits, and charges over the years available from 1993 to 2015. Using the Healthcare Cost and Utilization Project database, trends were identified in hospitalizations, emergency department visits, and charges from 1993 to 2015 for complications following kidney transplantation. Hospital discharges have significantly increased over time and at a faster rate than the increase in number of kidney transplants performed, while emergency department visits numbers and rates remain unchanged. The type of kidney transplant complications experienced were analyzed by incidence and proportion of total charges. Rejection made up the largest proportion of hospitalizations and of total cost in patients suffering from kidney transplant complications. Improved immunosuppression regimens have resulted in longer allograft survival. We speculate that the overlap between infection and rejection is compounding and contributing to graft injury and thus, it is important to try to prevent and/or properly identify those episodes as well in order to improve graft survival.
