Chen X, Xu J, Li Y, et al. - This study was intended to assess the potential role of abnormal electrolyte levels on predicting acute kidney injury (AKI) and severe AKI. Between October 01, 2014, and September 30, 2015, all hospitalized patients in our hospital in China were included. Researchers designed a retrospective, observational study including a total of 80,091 patients retrospectively and distributed them randomly into the test cohort and the validation cohort (2:1). They performed logistic regression in the test cohort to examine risk factors including electrolyte disorders and elucidate the relationship. The results of this study demonstrated that the risk scoring systems involving electrolyte disorders were established and validated adequately to prognosticate AKI and severe AKI in hospitalized patients. According to the findings, electrolyte imbalance needs to be carefully monitored and associations should be made on time to avoid further adverse outcomes.
