Hyperkalemia is associated with short- and mid-term mortalities in critically ill patients in the MIMIC IV database.

ABSTRACT: We aimed to explore the association of hyperkalemia and short- and mid-term mortality in critically ill patients using the Medical Information Mart for Intensive Care (MIMIC-IV) database. Adult patients who had been stayed in the intensive care unit (ICU) for at least 48 h and tested for serum potassium were included. Hyperkalemia was defined as serum potassium higher than 5.5 mmol/L. Exposures included the occurrence the timing of hyperkalemia and the numeric values of serum potassium. The outcomes included ICU mortality and 7 days and 30 days mortality after ICU admission. Survival curves were calculated according to Kaplan-Meier analysis. Univariate and multivariate Cox proportional hazard regression models were used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of
