Epidemiology of hyperkalemia among US emergency department patients without end-stage renal disease from 2016 to 2024.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Hyperkalemia is a potentially life-threatening condition among patients presenting to the emergency department (ED). However, most epidemiological studies have focused on those with end-stage renal disease (ESRD), and recent large-scale data on the incidence and management of hyperkalemia in non-ESRD ED patients remain limited. Methods: This was a retrospective cohort study of adults (≥18 years) without ESRD who presented to the ED with hyperkalemia between January 1, 2016, and December 31, 2024. Patients were identified using ICD-10 codes from the Epic Cosmos database. The primary outcome was the incidence of hyperkalemia among all ED visits. Secondary outcomes included admission rates, cardiac arrest, hemodialysis, and administration of medications used to treat hyperkalemia. Data were analyzed using summary statistics and odds ratios with 95% confidence intervals. Results: Among 246,235,769 ED visits, 803,186 (0.33%) had an ICD-10 code for hyperkalemia, and 539,033 (67.11%) of these patients were admitted to the hospital. Cardiac arrest occurred in 18,044 cases (2.25%). Sodium bicarbonate was administered in 38.75% of patients, calcium gluconate or chloride in 32.64%, sodium zirconium cyclosilicate in 24.68%, sodium polystyrene sulfonate in 23.12%, and patiromer in 3.04%. Only 2.99% received hemodialysis. Conclusion: Among adult ED patients without ESRD, hyperkalemia was uncommon but clinically important, with two-thirds requiring admission and approximately 2% experiencing cardiac arrest. Sodium bicarbonate and calcium were frequently administered, while hemodialysis was rare.
