Factors associated with accelerated parenteral weaning in children with intestinal failure: A descriptive cohort study

Background: The goal of intestinal rehabilitation in children is to wean from parenteral nutrition (PN). The aim of this study was to identify factors associated with accelerated weaning and to evaluate long-term outcomes of children receiving long-term PN. Methods: This was a retrospective study of children managed by the Intestinal Rehabilitation Center at Cincinnati Children's Hospital. Medical history data were retrieved. The outcomes of children receiving long-term chronic PN (>2 years) were compared with those of children receiving short-term chronic PN regimen (<2 years). Results: The cohort consisted of 112 children (58% boys, median [IQR] age of 6.0 [3.7-9.5] years). The group treated with a long-term PN regimen had significantly shorter residual small bowel and large bowel compared with the group treated with a short-term PN regimen (20% vs 60% and 75% vs 100%, respectively; P < 0.05). The lapse of time between PN and enteral feed initiation was longer in the group undergoing long-term PN regimen than in the short-term group (71 vs 32.5 days; P = 0.012). More episodes of central line-associated bloodstream infection (CLABSI) and a higher percentage of feeding aversion was demonstrated in the long-term PN group (2 [1-3] vs 1 [0-2] episodes and 36% vs 0%, respectively). Conclusion: Small bowel, colon length, enteral feed initiation, and frequency of CLABSI are factors associated with duration of PN regimen. A long-term chronic PN regimen is associated with a higher ri
