Study on the Prevalence and Risk Factors of Hyperkalemia in Brazilian Adults With Heart, Kidney, Diabetes, or Blood Pressure Conditions

What this Trial Is About

This observational study involves adults aged 18 and older who have heart failure, diabetes mellitus, chronic kidney disease, or systemic arterial hypertension. It focuses on patients from cardiology, nephrology, and dialysis clinics in Brazil who took part in the First National Campaign for the Diagnosis of Hyperkalaemia. Researchers aim to estimate how common hyperkalaemia is and describe the associated demographic profiles, clinical features, risk factors, and treatment patterns using anonymised data from the Hi Technologies Ltda. database. The study uses anonymised medical records collected during routine care from April to November 2025. Potassium levels were measured using a point-of-care device during consultations, allowing for timely data on blood potassium. There are no investigational treatments or interventions instead, the study observes existing management strategies in a real-world clinical setting. Participants data include demographic information, clinical history, and potassium levels. Researchers will analyze prevalence rates, clinical characteristics, and social impacts of hyperkalaemia over about one year. This includes reviewing epidemiological and clinical profiles, as well as practical and social outcomes. The study runs from March 2026 to September 2026, focusing on data analysis without active treatment or follow-up visits.
