PN order changes in study patients and controls

PN order changes	Study group (n=30)	Case-matched controls (n=30)
Macronutrients	104	73
Electrolytes	173	178
Micronutrients	42	12
Volume	33	24
Infusion rate	11	13
Total PN order changes	373	309

Note. PN orders for macronutrients were modified more often in study patients than in case-matched controls. Electrolytes, PN volume and duration were modified similarly among the study patients and case-matched controls. Micronutrients were modified in study patients more often than case-matched controls. The total number of PN formula changes were 20% higher in study patients than in case-matched controls.
