About this trial
The goal of this observational study is to investigate the prevalence and risk factors of hyperkalemia in community-based non-dialysis chronic kidney disease (CKD) patients. The main questions it aims to answer are:
1. What is the prevalence of hyperkalemia in non-dialysis CKD patients in a primary care setting? 2. What are the key risk factors influencing the occurrence of hyperkalemia in this population? Researchers will collect clinical and demographic data from participants across 18 community health centers and use both point-of-care testing (POCT) and laboratory-based methods to measure serum potassium levels and related parameters.
Participants will:
1. Provide blood samples for POCT and laboratory testing. 2. Participate in interviews or questionnaires to gather clinical and lifestyle information.
The findings will be used to construct a risk prediction model for hyperkalemia, aiming to optimize screening pathways and improve disease management strategies in primary care.

Treatments tested in this trial
No Intervention
Other interventionThis is an observational study with no interventions. POCT devices, provided by Eaglenos Sciences, Inc., are used to measure blood glucose, creatinine, uric acid, hemoglobin, and potassium levels in non-dialysis CKD patients for data collection purposes only.
Treatment groups
Trial outcomes
Primary outcomes
Prevalence of Hyperkalemia.
The proportion of non-dialysis CKD patients with hyperkalemia, defined as a blood potassium level greater than 5.0 mmol/L, measured using point-of-care testing (POCT) at enrollment.
Secondary outcomes
Association Between Hyperkalemia and Age.
Evaluates the association between hyperkalemia (blood potassium \> 5.0 mmol/L) and age (years) in non-dialysis CKD patients at enrollment, reported as odds ratios from univariate and multivariate logistic regression analyses.
Association Between Hyperkalemia and CKD Stage.
Evaluates the association between hyperkalemia (blood potassium \> 5.0 mmol/L) and CKD stage (1-5) in non-dialysis CKD patients at enrollment, reported as odds ratios from univariate and multivariate logistic regression analyses.
Association Between Hyperkalemia and Blood Glucose.
Evaluates the association between hyperkalemia (blood potassium \> 5.0 mmol/L) and blood glucose (mmol/L) in non-dialysis CKD patients using POCT at enrollment, reported as odds ratios from univariate and multivariate logistic regression analyses.
Association Between Hyperkalemia and Creatinine.
Evaluates the association between hyperkalemia (blood potassium \> 5.0 mmol/L) and creatinine (μmol/L) in non-dialysis CKD patients using POCT at enrollment, reported as odds ratios from univariate and multivariate logistic regression analyses
