Close to recommended caloric and protein intake by enteral nutrition is associated with better clinical outcome of critically ill septic patients: secondary analysis of a large international nutrition database.

ABSTRACT: INTRODUCTION: Current international sepsis guidelines recommend low-dose enteral nutrition (EN) for the first week. This contradicts other nutrition guidelines for heterogenous groups of ICU patients. Data on the optimal dose of EN in septic patients are lacking. Our aim was to evaluate the effect of energy and protein amount given by EN on clinical outcomes in a large cohort of critically ill septic patients. METHODS: We conducted a secondary analysis of pooled data collected prospectively from international nutrition studies. Eligible patients had a diagnosis of sepsis and/or pneumonia and were admitted to the ICU for ?3 days, mechanically ventilated within 48 hours of ICU admission and only receiving EN. Patients receiving parenteral nutrition were excluded. Data were collected from ICU admission up to a maximum of 12 days. Regression models were used to examine the impact of calorie and protein intake on 60-day mortality and ventilator-free days. RESULTS: Of the 13,630 patients included in the dataset, 2,270 met the study inclusion criteria. Patients received a mean amount of 1,057 kcal/d (14.5 kcal/kg/day) and 49 g protein/day (0.7 g/kg/d) by EN alone. Patients were mechanically ventilated for a median of 8.4 days and 60-day mortality was 30.5%. An increase of 1,000 kcal was associated with reduced 60-day mortality (odds ratio (OR) 0.61; 95% confidence interval (CI) 0.48 to 0.77, P <0.001) and more ventilator-free days (2.81 days, 95% CI 0.53 to 5.08, P?=?0.02) as was an increase of 30 g protein per day (OR 0.76; 95% CI 0.65 to 0.87, P <0.001 and 1.92 days, 95% CI 0.58 to 3.27, P?=?0.005, respectively). CONCLUSIONS: In critically ill septic patients, a calorie and protein delivery closer to recommended amounts by EN in the early phase of ICU stay was associated with a more favorable outcome.

Project description:ObjectivesTo evaluate the impact of implementing an enteral nutrition algorithm on achieving optimal enteral nutrition delivery in the PICU.DesignProspective pre/post implementation audit of enteral nutrition practices.SettingOne 29-bed medical/surgical PICU in a freestanding, university-affiliated children's hospital.PatientsConsecutive patients admitted to the PICU over two 4-week periods pre and post implementation, with a stay of more than 24 hours who received enteral nutrition.InterventionsBased on the results of our previous study, we developed and systematically implemented a stepwise, evidence and consensus-based algorithm for initiating, advancing, and maintaining enteral nutrition in critically ill children. Three months after implementation, we prospectively recorded clinical characteristics, nutrient delivery, enteral nutrition interruptions, parenteral nutrition use, and ability to reach energy goal in eligible children over a 4-week period. Clinical and nutritional variables were compared between the pre and postintervention cohorts. Time to achieving energy goal was analyzed using Kaplan-Meier statistical analysis.Measurements and main resultsEighty patients were eligible for this study and were compared to a cohort of 80 patients in the preimplementation audit. There were no significant differences in median age, gender, need for mechanical ventilation, time to initiating enteral nutrition, or use of postpyloric feeding between the two cohorts. We recorded a significant decrease in the number of avoidable episodes of enteral nutrition interruption (3 vs 51, p < 0.0001) and the prevalence and duration of parenteral nutrition dependence in patients with avoidable enteral nutrition interruptions in the postintervention cohort. Median time to reach energy goal decreased from 4 days to 1 day (p < 0.0001), with a higher proportion of patients reaching this goal (99% vs 61%, p = 0.01).ConclusionsThe implementation of an enteral nutrition algorithm significantly improved enteral nutrition delivery and decreased reliance on parenteral nutrition in critically ill children. Energy intake goal was reached earlier in a higher proportion of patients.

Project description:Background and aimsDespite enteral nutrition (EN) is the preferred route of nutrition in patients with critical illness, EN is not always able to provide optimal nutrient provision and parenteral nutrition (PN) is needed. This is strongly associated with gastrointestinal (GI) complications, a feature of gastrointestinal dysfunction and disease severity. The aim of the present study was to investigate factors associated with the need of PN after start of EN, together with the use and complications associated with EN.MethodsAdult patients admitted to 38 Spanish intensive care units (ICUs) between April and July 2018, who needed EN therapy were included in a prospective observational study. The characteristics of EN-treated patients and those who required PN after start EN were analyzed (i.e., clinical, laboratory and scores).ResultsOf a total of 443 patients, 43 (9.7%) received PN. One-third (29.3%) of patients presented GI complications, which were more frequent among those needing PN (26% vs. 60%, p = 0.001). No differences regarding mean energy and protein delivery were found between patients treated only with EN (n = 400) and those needing supplementary or total PN (n = 43). Abnormalities in lipid profile, blood proteins, and inflammatory markers, such as C-Reactive Protein, were shown in those patients needing PN. Sequential Organ Failure Assessment (SOFA) on ICU admission (Hazard ratio [HR]:1.161, 95% confidence interval [CI]:1.053-1.281, p = 0.003) and modified Nutrition Risk in Critically Ill (mNUTRIC) score (HR:1.311, 95% CI:1.098-1.565, p = 0.003) were higher among those who needed PN. In the multivariate analysis, higher SOFA score (HR:1.221, 95% CI:1.057-1.410, p = 0.007) and higher triglyceride levels on ICU admission (HR:1.004, 95% CI:1.001-1.007, p = 0.003) were associated with an increased risk for the need of PN, whereas higher albumin levels on ICU admission (HR:0.424, 95% CI:0.210-0.687, p = 0.016) was associated with lower need of PN.ConclusionA higher SOFA and nutrition-related laboratory parameters on ICU admission may be associated with the need of PN after starting EN therapy. This may be related with a higher occurrence of GI complications, a feature of GI dysfunction.Clinical trial registrationClinicalTrials.gov: NCT03634943.
