Clinical Trial Summary

This study aim to describe hyperkalemia clinical burden and investigate the risk factors associated with the burden on HD facility level.

Description:

This study is an observational survey study. We estimate 300 hemodialysis (HD) centres will be enrolled in the study. Summarized data on serum potassium (sK) after long interdialytic interval (LIDI), facility practice pattern and patient characteristics which may be related with sK management, and death records information including number of deaths for each centre will be collected. All the data collected and analysed are on HD facility level, not on patient-level. We are aiming to describe hyperkalemia clinical burden and investigate the risk factors associated with the burden on HD facility level. Association between sK management and long-term outcome will also be explored.
