United States Renal Data System ^ Nutrition/malnutrition Special Study Center

本合同支持美国肾脏数据系统（USRDS）国家登记研究。 USRDS是美国所有终末期肾病（ESRD）患者的纵向登记研究。 这包括所有接受透析和肾移植的人。 该数据库包括从1980年至今的所有ESRD事件病例。 关于ESRD患者的信息包括肾衰竭的日期和原因以及合并症。 此外，后续数据包括死亡率、住院率和其他发病率和残疾指标以及支出数据。 此外，USRDS还包括慢性肾脏疾病患者的类似信息。 患有ESRD的人不成比例地遭受营养状况不良。 这在肾脏替代疗法开始时和人们接受透析治疗时都是如此。

This contract is in support of the United State Renal Data System (USRDS) national registry. The USRDS is a longitudinal registry of all persons in the US who have end stage renal disease (ESRD). This includes all persons on dialysis and recipients of kidney transplantation. The data base is inclusive of all incident cases of ESRD from 1980 to the present. Information on ESRD patients include date and cause of renal failure as well as co-morbid conditions. In addition, follow-up data include mortality, hospitalization and other indicators of morbidity and disability, as well as expenditure data. In addition, the USRDS includes similar information on persons with chronic kidney disease. Persons with ESRD suffer disproportionately from poor nutritional status. This is true at the start of renal replacement therapy and worsens as people are treated with dialysis.
