Official title
Investigating the Impact of Serum Potassium Levels on Prevalence and Risk Factors Associated With Management Strategies for Patients With Hyperkalaemia in Brazilian Clinical Settings: An Observational Study.
Overview
This is a descriptive, retrospective study involving patients from private cardiology, nephrology, and dialysis clinics in Brazil who participated in the National Hyperkalaemia Diagnosis Campaign. The study used anonymised data from the Hi Technologies Ltda. database. The objective was to estimate and characterise the prevalence of hyperkalaemia (HK), as well as to analyse the demographic profile, clinical characteristics, risk factors and treatment patterns associated with total blood potassium levels.
Detailed description
The aim of this study is to describe the clinical and demographic profile, as well as the prevalence of hyperkalaemia and its associated risk factors in patients who participated in the First National Campaign for the Diagnosis of Hyperkalaemia through the incorporation of a point-of-care device, with potassium results available during the consultation. The data used in this study consists of anonymised records. The study population will consist of adults aged 18 years or older, of both sexes, with a medical history of heart failure, diabetes mellitus, chronic kidney disease, and/or systemic arterial hypertension, who attended cardiology, nephrology, or dialysis clinics between April and November 2025.
Primary outcome measures
- Prevalence of Hyperkalemia [Time frame: through study completion, an average of 1 year]
- Epidemiological and Clinical Characterisation [Time frame: through study completion, an average of 1 year]
Secondary outcome measures (1)
- Practical and Social Impact [Time frame: through study completion, an average of 1 year]
Eligibility criteria
