Visual summary
Improving an adequacy number beyond an effective range does not automatically improve survival or wellbeing. Ask what patient problem the change is intended to solve.
Text version
Adequacy metrics describe part of care
Urea-based measures reflect small-solute removal. They do not capture every toxin, symptom, or consequence of treatment.
Check delivered therapy
Treatment time, access function, interruptions, recirculation, and sampling technique can distort or reduce measured delivery.
Review the monthly pattern
Interpret chemistry, anemia, nutrition, mineral metabolism, symptoms, and volume together. A green laboratory dashboard can coexist with poor function.
Include mental and cognitive health
Depression, impaired cognition, sleep, and treatment burden affect quality of life and attendance. Appropriate assessment and support belong in routine care.
Nursing contribution
Identify trends, verify sampling, report symptoms and barriers, and connect laboratory changes to what occurred during treatment.
Avoid chasing a surrogate alone
Improving an adequacy number beyond an effective range does not automatically improve survival or wellbeing. Ask what patient problem the change is intended to solve.
