Prognostic value of different cut-off points of the NRS-2002 tool to identify nutritional risk in critically ill patients: a longitudinal study.

The American Society of Parenteral and Enteral Nutrition recommends nutritional risk (NR) screening in critically ill patients with Nutritional Risk Screening - 2002 (NRS-2002) ≥ 3 as NR and ≥ 5 as high NR. The present study evaluated the predictive validity of different NRS-2002 cut-off points in intensive care unit (ICU). A prospective cohort study was conducted with adult patients who were screened using the NRS-2002.

A systematic review on the agreement between clinical practice guidelines regarding the steps of the nutrition care process of adult patients who are critically ill.

Background: Clinical practice guidelines (CPGs) for the nutrition management of adult patients who are critically ill present divergences on recommendations regarding the nutrition care process (NCP), which bring difficulties in their application. We aimed to compare the recommendations from these CPGs and present a synthesis of them for each step of the NCP in intensive care unit (ICU) settings.

Methods: Systematic review of CPGs on nutrition care in ICU, searched in six databases up to January 2022.

Quality appraisal of clinical nutrition practice guidelines for critically ill adult patients: a systematic review using the Advancing Guideline Development, Reporting and Evaluation in Health Care instrument II (AGREE-II) and AGREE-Recommendation Excellence (AGREE-REX).

Nutritional therapy should follow evidence-based practice, thus several societies regarding nutrition and critical care have developed specific Clinical Practice Guidelines (CPG). However, to be regarded as trustworthy, the quality of the CPG for critically ill patients and its recommendations need to be high. This systematic review aimed to appraise the methodology and recommendations of nutrition CPG for critically ill patients.

Nutritional risk in critically ill patients: how it is assessed, its prevalence and prognostic value: a systematic review.

Context: Nutritional risk (NR) screening is the first step of nutrition care process. Few data are available in literature about its prevalence, nor, to our knowledge, is a universally accepted reference method for the intensive care unit (ICU).

Objective: The aim for this systematic review was to summarize evidence regarding the prevalence of NR and the predictive validity of different tools applied for NR screening of critically ill patients.
