Prevalence and Risk Factors of Hyperkalemia in Non-Dialysis Chronic Kidney Disease Patients in a Community-Based Primary Care Setting
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.
