Dfr

An shift in DFR from 500 to 800 ml/min might only increase clearance by 10%. Though many centers use an DFR of 800 ml/min, they could get the same additional clearance by running the patient 15 minutes longer.

When the dfr (Qd) is reduced 25% ( 800 to 600 ml/min) as cost saving measure, how does that affect patients’ health?
