If high, check the dose of epoetin or other
erythropoiesis-stimulating agents. If low, check
ferritin stores, transferrin saturation, and iron
stores; increase epoetin or other erythropoiesis-
stimulating agent. If no response, check folate and
vitamin B 12 levels (8).

Ferritin 12 - 800 ng/L 100 - 800 ng/L If high, decrease iron supplementation; check for
chronic inflammation.
II. Medications
Drug Approaches
Phosphate binders Phosphate binders may decrease level of dietary phosphorus restriction.


Diuretics If effective, diuretics may decrease level of sodium restriction. Diuretics may
increase blood urea nitrogen levels and decrease potassium levels.

III. Other Parameters
Parameter Goal Approaches
Interdialytic weight gain 1 - 2 lb/day
2%-5% of body weight^ (9)

If high, limit fluid and sodium intake.
If low, modify fluid intake.
Dialysis adequacy assessed by
urea kinetic modeling (1):
Kt/V (URR)d

nPNA (1-3)

Kt/V >1.2 or URR <65 in
hemodialysis (1)
Weekly Kt/V >2.0,
creatinine clearance >60
L/week per 1.73 m^2 in
CAPD (1)
nPNA >1.2 (2,3)

Evaluate adequacy of dialysis and protein
metabolism.
Refer to guidelines (1-3) for detailed discussion of
urea kinetic modeling.

Glomerular filtration intake and
creatinine clearance

Based on stage of CKD (1-5) See discussion of glomerular filtration rate
earlier in this section.
Urine Albumin-to-Creatinine
Ratio (UACR)

< 30 mg/g UACR estimates 24 –hour urine albumin
excretion. Albuminuria is present when UACR
is > 30 mg/g and is a marker for CKD. This
parameter is used to diagnoise and monitor
kidney disease. Change in albuminuria may
reflect response to therapy and risk for
progression. Refer to K/DOQI guidelines.
Hypertension

Heart failure

Edema

<130/80 mm Hg (Grade IV)* (10)

Individualized based on
symptoms

Individualized based on

Restrict sodium.

Restrict sodium and fluid as needed

Restrict sodium and fluid as needed

Hypotension >90/60 Assess sodium and fluid intake.

Urine output Individualized based on
symptoms

Adjust fluid intake based on urine output to
maintain stable dry weight.

Food intake >80% estimated energy
expenditure (1)

Modify nutrition treatment plan and diet
restrictions to increase food intake.
