Association between Serum Potassium and Outcomes in Patients with Reduced Kidney Function

Background and objectives Patients with CKD are more likely than others to have abnormalities in serum potassium (K+). Aside from severe hyperkalemia, the clinical significance of K+ abnormalities is not known. We sought to examine the association of serum K+ with mortality and hospitalization rates within narrow eGFR strata to understand how the burden of hyperkalemia varies by CKD severity. Associations were examined between serum K+ and...
