ABSTRACT

Introduction: the incidence of acute kidney injury in the emergency department is poorly understood, and is associated with prolonged stay, mortality, and costs.
Objective: to determine the incidence of acute kidney injury in patients hospitalized in the emergency department.
Material and methods: descriptive cross-sectional design in patients admitted to the emergency department from September 2022 to October 2023. All those who presented creatinine less than 1.0 mg/dl were included and those diagnosed with chronic kidney disease, or those who were identified with data of chronic kidney disease during their stay, were excluded. The sample size was n=112. The diagnosis was established after 6 hours of stay using the uresis criterion ‹0.5ml/kg/hours. When the stay was ≥48 h, an increase in serum creatinine ≥0.30mg/dl compared to admission was considered. The statistical analysis included averages, percentages, and confidence intervals.
Results: 23.2% (95% CI, 15.2 – 31.1) of patients who were admitted to the emergency room without impaired renal function developed acute kidney injury.
Conclusion: one in 4 patients treated in the emergency room develops acute kidney injury.
