Dialysis and nutrition prescriptions are based on objective and subjective measures that determine how well the child is growing and developing. To optimize the care of children treated with MD, a series of parameters associated with nutritional adequacy have been defined by the Work Group (Table 1). The recommended intervals are minimum ones, and the clinician is encouraged to obtain them more frequently if it is felt that the patient may benefit. Infants in particular may need very close follow-up (every 1 to 2 weeks initially) to monitor adequacy of the diet prescription, feeding tolerance, and growth parameters.31,32
