# N19 — Dialysis Adequacy and Quality Review

N19 — Dialysis Adequacy and Quality Review FRONT Front · at the chair

**When:** The monthly adequacy result, recurrent shortened sessions, or symptoms despite an acceptable Kt/V.

### Do this

1.  Confirm sampling technique and timing for pre/post urea. Compare delivered treatment time with the prescription and identify missed or shortened sessions.
2.  Review blood-flow delivery, repeated alarms, interruptions, access findings, and recent access procedures when Kt/V falls.
3.  For conventional three-times-weekly HD, distinguish the KDOQI target spKt/V of 1.4 from the minimum delivered value of 1.2 \[[1](https://urinenephrology.org/mastery/maintenance-hd/nursing/N19-Dialysis-Adequacy-and-Quality-Review.html#n19-ref-1)\]. Report results below the prescribed goal.
4.  Review symptoms, volume tolerance, recovery time, intake/weight change, function, and the patient's own priorities alongside adequacy.

### Call / escalate

- An unexplained fall or result below target, recurrent inability to complete treatment, or an abnormal access examination: arrange prompt team review.
- Breathlessness, chest pain, confusion, arrhythmia symptoms, or acute access failure: use the urgent clinical pathway; do not wait for monthly rounds.

### Don't

- Do not shorten prescribed treatment because Kt/V is above a threshold.
- Do not apply a per-session spKt/V target to a different dialysis schedule without the nephrologist's prescription, or change blood flow, time, or dialyzer independently.

N19 — Dialysis Adequacy and Quality Review BACK Back · why, and the evidence

### Why

- Kt/V describes urea clearance. It does not measure every treatment goal or capture how a patient feels \[[1](https://urinenephrology.org/mastery/maintenance-hd/nursing/N19-Dialysis-Adequacy-and-Quality-Review.html#n19-ref-1),[2](https://urinenephrology.org/mastery/maintenance-hd/nursing/N19-Dialysis-Adequacy-and-Quality-Review.html#n19-ref-2)\].
- The HEMO trial did not find an overall survival benefit from increasing the small-solute dose above the standard-dose arm. Meeting a minimum is necessary; chasing a higher number is not a complete quality plan \[[2](https://urinenephrology.org/mastery/maintenance-hd/nursing/N19-Dialysis-Adequacy-and-Quality-Review.html#n19-ref-2)\].
- A meaningful review connects the result to delivered treatment, access performance, safety, nutrition, symptoms, and patient goals.

### Bring this to the review

Prescription and actual minutes; sampling method; Kt/V trend; missed sessions; blood-flow/pressure alarms; access findings; symptoms and recovery time; barriers and a specific follow-up plan.
