Objective: To investigate the clinical utility of administering patiromer as an adjunct to insulin for potassium reduction in patients presenting to the emergency department (ED) with hyperkalemia.
Methods: This retrospective cohort study used electronic health record data to identify adults treated with at least one intravenous dose of regular insulin for hyperkalemia within the ED. Patients who were administered patiromer within one hour before or after their insulin dose were categorized as the intervention group.
