A.S.P.E.N. Clinical Guidelines

Background: Children with severe intestinal failure and prolonged dependence on parenteral nutrition are susceptible to the development of parenteral nutrition–associated liver disease (PNALD). The purpose of this clinical guideline is to develop recommendations for the care of children with PN‐dependent intestinal failure that have the potential to prevent PNALD or improve its treatment. Method: A systematic review of the best available evidence to answer a series of questions regarding clinical management of children with intestinal failure receiving parenteral or enteral nutrition was undertaken and evaluated using concepts adopted from the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group. A consensus process was used to develop the clinical guideline recommendations prior to external and internal review and approval by the American Society for Parenteral and Enteral Nutrition Board of Directors. Questions: (1) Is ethanol lock effective in preventing bloodstream infection and catheter removal in children at risk of PNALD? (2) What fat emulsion strategies can be used in pediatric patients with intestinal failure to reduce the risk of or treat PNALD? (3) Can enteral ursodeoxycholic acid improve the treatment of PNALD in pediatric patients with intestinal failure? (4) Are PNALD outcomes improved when patients are managed by a multidisciplinary intestinal rehabilitation team?     

Clinical Outcomes in Critically Ill Patients Associated With the Use of Complex vs Weight‐Only Predictive Energy Equations

Background: The energy intake goal is important to achieving energy intake in critically ill patients, yet clinical outcomes associated with energy goals have not been reported. Methods: This secondary analysis used the Improving Nutrition Practices in the Critically III International Nutrition Surveys database from 2007–2009 to evaluate whether mortality or time to discharge alive is related to use of complex energy prediction equations vs weight only. The sample size was 5672 patients in the intensive care unit (ICU) ≥4 days and a subset of 3356 in the ICU ≥12 days. Mortality and time to discharge alive were compared between groups by regression, controlling for age, sex, admission type, Acute Physiology and Chronic Health Evaluation II score, ICU geographic region, actual energy intake, and obesity. Results: There was no difference in mortality between the use of complex and weight‐only equations (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.86–1.15), but obesity (OR, 0.83; 95% CI, 0.71–0.96) and higher energy intake (OR, 0.65; 95% CI, 0.56–0.76) had lower odds of mortality. Time to discharge alive was shorter in patients fed using weight‐only equations (hazard ratio [HR], 1.11; 95% CI, 1.01–1.23) in patients staying ≥4 days and with greater energy intake (HR, 1.19; 95% CI, 1.06–1.34) in patients in the ICU ≥12 days. Conclusion: These data suggest that higher energy intake is important to survival and time to discharge alive. However, the analysis was limited by actual energy intake <70% of goal. Delivery of full goal intake will be needed to determine the relationship between the method of determining energy goal and clinical outcomes.
