The aim of this study was to determine the incidence of treatment of hyperkalemia in hospitalized patients. ⋯ Almost all the patients were treated for hyperkalemia. Oral SPS monotherapy was the predominant treatment with the best response at the highest dose. Some combination therapies had greater K reductions but were used infrequently. An ECG was obtained in about 50% of the cases, but two thirds showed no K-related changes. Reduced kidney function was associated with 70% of hyperkalemic episodes. Angiotensin-converting enzyme inhibitors and trimethoprim were the most commonly implicated medications.
