Demographics and Clinical Outcomes of Hyperkalemia in Hospitalized Patients: A Detailed Examination

Key Points

Severe hyperkalemia was linked to an 8% mortality rate among patients with multiple comorbidities, indicating serious health risks.
Analysis of 300 hospitalized patients showed an average age of 65, with 60% of cases occurring in males.
Data collected on demographics and treatment included serum potassium levels, showing an average of 6.2 mmol/L in patients.
Patients with chronic kidney disease and heart failure require ongoing monitoring and early intervention for better long-term outcomes.

Abstract

Background: Hyperkalemia is a potentially life-threatening condition that occurs commonly in hospitalized patients, especially in those with chronic kidney disease or heart failure. The ones who present with chronic cough are usually the more difficult, and understanding their demographics and clinical profile is necessary in order to manage them better. Objectives: to investigate the demographics, clinical features and treatment outcomes among hospitalized patients presenting with Hyperkalemia. Study design: A retrospective study. Duration and place of study: department of Nephrology Maingul Jehanzab Hospital swat from Jan 2023 to Jan 2024 Methods: This retrospective study analyzed 300 hospitalized hyperkalemia patients' medical records from January 2022 to December 2023. Data included demographics, pre-existing conditions, serum potassium levels, and treatment strategies. Statistical analysis using SPSS 24.0 evaluated the relationship between hyperkalemia severity, management approaches, and outcomes, with significance set at p < 0.05. Results: Of the 300 patients, 60% were male; the average age was 65. Kidney function was impaired chronically in 45% of the cases, and withheld failure occurred in up to 30%. The mean serum potassium was 6.2 mmol/L, while the administered treatments were IV calcium, insulin+glucose and diuretics. An 8% mortality rate was recorded, the majority of whom had severe Hyperkalemia (≥7.0 mmol/L) and multiple comorbidities. Conclusion: Hyperkalemia is most often in the setting of chronic kidney disease and heart failure. Early recognition and early treatment provide good outcomes, albeit a worse prognosis for the opportunity of severe illness having hat only one comorbidity in mobile patients. Patients require continual review and early intervention to enable them to have better, longer-term outcomes.
