Abstract Malnutrition and acute kidney injury (AKI) are common complications in hospitalised patients, both increase mortality; however, the relationship between them is unknown. This a retrospective propensity score matching study enrolling 46 549 inpatients, aimed to investigate association Nutritional Risk Screening 2002 (NRS-2002) AKI assess ability of NRS-2002 predicting prognosis. In total, 37 190 (80 %) 9359 (20 patients had scores <3 ≥3, respectively. Patients with ≥3 longer lengths stay (12·6 ( sd 7·8) v . 10·4 6·2) d, P < 0·05), higher mortality rates (9·6 2·5 %, 0·05) incidence (28 16 than normal nutritional status.
