Hyperkalemia management in the emergency department: An expert panel consensus.

ABSTRACT: Hyperkalemia is a common electrolyte abnormality identified in the emergency department (ED) and potentially fatal. However, there is no consensus over the potassium threshold that warrants intervention or its treatment algorithm. Commonly used medications are at best temporizing measures, and the roles of binders are unclear in the emergent setting. As the prevalence of comorbid conditions altering potassium homeostasis rises, hyperkalemia becomes more common, and hence there is a need to standardize management. A panel was assembled to synthesize the available evidence and identify gaps in knowledge in hyperkalemia treatment in the ED. The panel was composed of 7 medical practitioners, including 5 physicians, a nurse, and a clinical pharmacist with collective expertise in the areas of emergency medicine, nephrology, and hospital medicine. This panel was sponsored by the American College of Emergency Physicians with a goal to create a consensus document for managing acute hyperkalemia. The panel evaluated the evidence on calcium for myocyte stabilization and potassium shifting and excretion. This article summarizes information on available therapies for hyperkalemia and proposes a hyperkalemia treatment algorithm for the ED practitioner based on the currently available literature and highlights diagnostic pitfalls and evidence gaps.

Project description:IntroductionHyperkalemia is often managed in the emergency department (ED) and it is important to understand how ED management and post-discharge outcomes vary by hyperkalemia severity. This study was conducted to characterize ED management and post-discharge outcomes across hyperkalemia severities.MethodsAdults with an ED visit with hyperkalemia (at least one serum potassium lab measure above 5.0 mEq/L) were selected from US electronic medical record data (2012-2018). Patient characteristics, potassium levels, treatments, and monitoring prior to and during the ED visit were compared by hyperkalemia severity (mild [> 5.0-5.5 mEq/L], moderate [> 5.5-6.0], severe [> 6.0]) using unadjusted analyses. Death, immediate inpatient admission, 30-day hyperkalemia recurrence, and 30-day inpatient admission were also assessed by severity.ResultsOf 6222 patients included, 4432 (71.2%) had mild hyperkalemia, 1085 (17.4%) had moderate, and 705 (11.3%) had severe hyperkalemia. Chronic kidney disease (39.9-50.1%) and heart failure (21.6-24.3%) were common. In the ED, electrocardiograms (mild, 56.5%; moderate, 69.6%; severe, 81.0%) and patients with at least two potassium laboratory values increased with severity (15.0%; 40.4%; 75.5%). Among patients with at least two potassium laboratory values, over half of patients (60.4%) had potassium levels ≤ 5.0 mEq/L prior to discharge. Use of potassium-binding treatments (sodium polystyrene sulfonate: mild = 4.1%; moderate = 17.1%; severe = 27.4%), temporizing agents (5.6%; 15.5%; 31.6%), or dialysis (0.4%; 0.8%; 3.0%) increased with severity; treatment at discharge was not common. Death (1.1%; 3.7%; 10.6%), immediate admission to inpatient care (5.8%; 8.7%; 12.7%), 30-day hyperkalemia recurrence (2.9%; 19.0%; 32.5%), 30-day inpatient admission with hyperkalemia (6.5%; 7.9%; 9.3%) also increased with severity.ConclusionPatients with moderate and severe hyperkalemia experienced elevated risk of hyperkalemia recurrence and hyperkalemia-related inpatient readmission following discharge from the ED from a descriptive analysis. Future research to assess strategies to reduce hyperkalemia recurrence and inpatient admission in this patient population would be beneficial.

Project description:AimsTreatment guidelines with respect to unspecified anxiety disorder have not been published. The aim of this study was to develop a consensus among field experts on the management of unspecified anxiety disorder.MethodsExperts were asked to evaluate treatment choices based on eight clinical questions concerning unspecified anxiety disorder using a nine-point Likert scale (1 = "disagree" to 9 = "agree"). According to the responses from 119 experts, the choices were categorized into first-, second-, and third-line recommendations.ResultsBenzodiazepine anxiolytic use was not categorized as a first-line recommendation for the primary treatment of unspecified anxiety disorder, whereas multiple nonpharmacological treatment strategies, including coping strategies (7.9 ± 1.4), psychoeducation for anxiety (7.9 ± 1.4), lifestyle changes (7.8 ± 1.5), and relaxation techniques (7.4 ± 1.8), were categorized as first-line recommendations. Various treatment strategies were categorized as first-line recommendations when a benzodiazepine anxiolytic drug did not improve anxiety symptoms, that is, differential diagnosis (8.2 ± 1.4), psychoeducation for anxiety (8.0 ± 1.5), coping strategies (7.8 ± 1.5), lifestyle changes (7.8 ± 1.5), relaxation techniques (7.2 ± 1.9), and switching to selective serotonin reuptake inhibitors (SSRIs) (7.0 ± 1.8). These strategies were also highly endorsed when tapering the dosage of or discontinuing benzodiazepine anxiolytic drugs. There was no first-line recommendation regarding excusable reasons for continuing benzodiazepine anxiolytics.ConclusionsThe field experts recommend that benzodiazepine anxiolytics should not be used as a first-line option for patients with unspecified anxiety disorder. Instead, several nonpharmacological interventions and switching to SSRIs were endorsed for the primary treatment of unspecified anxiety disorder and as alternatives to benzodiazepine anxiolytics.
