Effects of a nutrition support team on clinical outcomes, metabolic complications and electrolyte abnormalities in patients receiving parenteral nutrition

The effectiveness of the Nutrition Support Team (NST) at Hospital Sungai Buloh, a large public hospital in Kuala Lumpur, Malaysia, in optimising parenteral nutrition (PN) has not been evaluated. To evaluate the effects of this NST in optimising patient outcomes, treatment outcomes, and adherence to biochemical monitoring guidelines, two groups of patients, those given PN before (n = 106) NST intervention and those given PN after (n=106) NST intervention, were retrospectively compared. Intervention by the NST significantly reduced metabolic abnormalities, reducing sodium abnormalities from 67% to 44% (p<0.01); potassium abnormalities from 42% to 15% (p<0.01); magnesium abnormalities from 13% to 3% (p<0.05) and phosphate abnormalities from 21% to 9% (p=0.01). Intervention by the NST also significantly reduced the incidence of hypertriglyceridemia from 68% to 45% (p=0.002) and significantly improved adherence to biochemical monitoring guidelines from 46% to 72% (p<0.01). However, the length of hospital stay, patient mortality, and duration of PN were similar in both groups. This study failed to demonstrate that the establishment of a NST gave better outcomes in terms of the common measures of effectiveness. In conclusion, although management by an NST significantly reduced metabolic abnormalities and improved adherence to biochemical monitoring guidelines, the NST did not improve patient mortality rates and length of hospital stay.
