Background & aim: Majority of the National Institute of Clinical Excellence (NICE) nutrition guidance recommendations were based on Grade D evidence due to absence of randomised controlled trials. The aim was to assess outcomes of parenteral nutrition (PN) administration when the guidance was adhered to.
Methods: The prospective study included patients referred for PN. Patients were divided into two groups: guidance compliant and guidance non-compliant Primary outcome measures were duration of PN treatment, number of PN bags used per patient, length of hospital stay and mortality.
Results: There were 262 patients, aged 54(42-67) [median (IQR)] years. The guidance compliant and the non-compliant groups consisted of 143 and 119 patients respectively. In the guidance compliant group all patients were screened on admission compared to 40% in the non-compliant group (p < 0.001). Among those malnourished/at risk of malnutrition all were referred for early dietetic assessment in the compliant group but only 14% in the non-compliant group (p < 0.001). There was no difference in any of the outcome measures between the groups.
Conclusion: Compliance with the nutritional guidance in the UK was not enough to improve outcomes in patients requiring PN in our cohort. Evidence based changes to PN practice are required to optimise care.
