Assessment of parenteral nutrition prescription in Canadian acute care settings

Abstract Background Parenteral nutrition (PN) prescription can be challenging in patients with complex conditions and has potential complications. Objective To assess PN prescription, monitoring, and PN-related complications in a Canadian acute care setting. Methods This was a prospective cohort study in which patients receiving PN were assessed by an auditor for nutritional status, PN-related prescription, monitoring, and complications. In addition, length of stay and mortality were recorded. Results 147 patients (mean ± SD 56.1 ± 16.4 y) with complex diseases (Charlson comorbidity index, median [p25–p75] 2 [1–4]) were enrolled. Before starting PN, 18.6%, 63.9%, and 17.5% of patients were classified as subjective global assessment A, B, and C, respectively. Body mass index remained unchanged during the period on PN. On average, 89% and 73% of patients received Conclusion Most patients were malnourished at the start of PN. Energy and protein provided from PN were less than requirements, and the goals were reached with delay. Mortality was high, possibly as a result of complex diseases.
