Could frequent filter changes cut infections in kidney dialysis?
NCT ID NCT07630220
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether changing the filter in a kidney dialysis machine more often than usual can lower the chance of new infections in critically ill patients with severe acute kidney injury. About 100 adults in intensive care will be randomly assigned to have their filter changed every 36 hours or every 48-72 hours. The goal is to see if the shorter filter lifespan is practical and helps reduce infections.
