BACKGROUND: Nutrition support teams (NST) may improve parenteral nutrition (PN) outcomes. No previous systematic review has provided conclusive data on catheter-related infection (CRI) occurrence after NST introduction, nor have previous studies performed meta-analysis or graded the evidence.

AIMS: To systematically evaluate the effects of implementing an NST for hospitalised adults on PN and compare these with standard care.

METHODS: This was a systematic review and meta-analysis, pre-registered in PROSPERO (CRD42020218094). On November 24, 2020, PubMed, Web of science, Scopus, Embase, Cochrane Library, and Clinical Key were searched. Clinical trials and observational studies with a standard care comparator were included. Primary outcome was relative reduction in CRI rate. A random-effects meta-analysis was used to estimate effects, and evidence was rated using Cochrane and GRADE methodologies.

RESULTS: Twenty-seven studies with 8166 patients were included. Across 10 studies, NST introduction reduced the CRI rate (IRR = 0.32, 95% CI: 0.19-0.53) with -8 (95% CI: -12 to -5) episodes per 1000 catheter days compared with standard care. Hypophosphataemia occurred less frequently (IRD = -12%, 95% CI: -24% to -1%) and 30-day mortality decreased (IRD = -6%, 95% CI: -11% to -1%). Inappropriate PN use decreased, both judged by indication (IRD = -18%, 95% CI: -28% to -9%) and duration (IRD = -21%, 95% CI: -33% to -9%). Evidence was rated very low to moderate.

CONCLUSIONS: This study documents the clinical impact of introducing an NST, with moderate-grade evidence for the reduction of CRI occurrence compared with standard care. Further, NST introduction significantly reduced metabolic complications, mortality, and inappropriate PN use.
