Changes in nutritional status in ICU patients receiving enteral tube feeding: a prospective descriptive study

Factors Associated with Nutritional Risk Assessment in Critically Ill Patients Using the Malnutrition Universal Screening Tool (MUST)

Background: Malnutrition is an underdiagnosed condition that negatively affects the clinical outcomes of patients, being associated with an increased risk of adverse events, increased hospital stay, and higher mortality. Therefore, nutritional assessment is a required and necessary process in patient care. The objective of this study was to identify the factors associated with nutritional risk by applying the Malnutrition Universal Screening Tool (MUST) scale in a population of critically ill patients. Methods: This was an observational, analytical, and retrospective study. Sociodemographic, clinical, hematological, and biochemical variables and their relationship with nutritional risk and mortality were analyzed. Results: Of 630 patients, the leading cause of admission was pathologies of the circulatory and respiratory system (50%); 28.4% were at high nutritional risk; and mortality was 11.6% and associated with nutritional risk, hemoglobin, and plasma urea nitrogen. Conclusions: The presence of gastrointestinal symptoms and the type of nutritional support received during hospitalization could increase the likelihood of presenting a medium/high nutritional risk, while polycythemia reduced this probability. An associative model was found to determine nutritional risk with an adequate specificity and diagnostic validity index.

Palestinian nurses' knowledge, attitudes, and practices regarding enteral nutrition: Cross-sectional study

BACKGROUND

Enteral nutrition support plays a key role in minimizing malnutrition in critically-ill patients, and its provision is originally a nurse's responsibility. Thus, nurses need to have a sufficient knowledge and a positive attitude with regard to enteral nutrition. In Palestine, literature regarding nurses' knowledge, practices, and attitudes of enteral nutrition is rare.

OBJECTIVE

This study aimed to investigate Palestinian nurses' knowledge, practices, and attitudes regarding enteral nutrition.

METHOD

Interview based pre-tested questionnaire was used during data collection procedure. Cronbach Alpha was also used to determine the reliability of knowledge, attitude and practice questionnaire. Descriptive statistics, independent t-test, and ANOVA were performed.

RESULTS

A total of 325 registered nurses were involved in the final analysis. The mean of the knowledge score is (9.6 ± 2.8) out of 20. It was confirmed that sociodemographic characteristics has no influence on nutrition knowledge score among nurses. The findings also reveal that certain aspects of enteral nutrition practices were consistent with the current guidelines such as flushing the tube and backrest elevation. On the other hand, certain practices showed inconsistency and differences with international guidelines such as checking gastric residual volume. Results also showed that nurses attitudes were positive towards enteral nutrition.

CONCLUSION

It was found that nurses' have inadequate knowledge regarding enteral nutrition. The findings also showed that enteral nutrition practices among nurses were somewhat incongruent with best current evidence. However, it was noted that they have positive attitudes towards enteral nutrition. Promoting research utilization is highly needed as well as establishing evidence-based guidelines.

Validation of GLIM malnutrition criteria for diagnosis of malnutrition in ICU patients: An observational study

BACKGROUND & AIMS

Patients in the Intensive Care Unit (ICU) are at high risk of malnutrition. The only validated malnutrition assessment tool is the Subjective Global Assessment (SGA). The Global Leadership Initiative on Malnutrition (GLIM) is a new malnutrition assessment tool. The present study compares the nutrition-related parameters of the following tools: GLIM tool, SGA, Phase Angle (PA), Low Fat-Free Mass Index (FFMI), and Patient- and Nutrition-Derived Outcome Risk Assessment score (PANDORA), in an attempt to validate an objective tool.

METHODS

Eighty-four ICU patients were included. The tools mentioned above were assessed for their validity in diagnosing malnutrition. All patients were defined as suffering from acute disease and received medical nutrition therapy. To evaluate whether there is a correlation between the GLIM criteria, SGA, PA, and low FFMI, we compared the SGA, PA, and low FFMI to the GLIM criteria using Spearman correlation coefficients and a Chi-square test. Also, a Mann-Whitney U test was used to test the mean differences between the GLIM criteria and the PANDORA. The area under the curve (AUC) of the proposed parameters was evaluated for diagnosis of malnutrition to seek cutoff points that yield good sensitivity and specificity.

RESULTS

Mean age was 50 ± 20 years, BMI 25.3 ± 5.1 kg/m², APACHE II 20.5 ± 7.7, PANDORA score 32 ± 8.5. GLIM malnutrition criteria were significantly correlated with the gold standard SGA assessment and with low FFMI, with PA (Phase Angle), and with the PANDORA score. The area under the curve, by using the ROC curve analysis for GLIM criteria stratified by the SGA results, was 0.85 (P < 0.001). Sensitivity was 85%, and specificity 79%. However, when comparing the low FFMI, PA, and PANDORA to the GLIM criteria, the ROC curve analysis results were considered poor rank.

CONCLUSIONS

The SGA malnutrition assessment highly validated the GLIM criteria framework combined with the two-criteria diagnosis of malnutrition with a high level of precision. The GLIM malnutrition assessment seems to be acceptable in the ICU setting.

Quantifying Response to Nutrition Therapy During Critical Illness: Implications for Clinical Practice and Research? A Narrative Review

Critical illness causes substantial muscle loss that adversely impacts recovery and health-related quality of life. Treatments are therefore needed that reduce mortality and/or improve the quality of survivorship. The purpose of this Review is to describe both patient-centered and surrogate outcomes that quantify responses to nutrition therapy in critically ill patients. The use of these outcomes in randomized clinical trials will be described and the strengths and limitations of these outcomes detailed. Outcomes used to quantify the response of nutrition therapy must have a plausible mechanistic relationship to nutrition therapy and either be an accepted measure for the quality of survivorship or highly likely to lead to improvements in survivorship. This Review identified that previous trials have utilized diverse outcomes. The variety of outcomes observed is probably due to a lack of consensus as to the most appropriate surrogate outcomes to quantify response to nutrition therapy during research or clinical practice. Recent studies have used, with some success, measures of muscle mass to evaluate and monitor nutrition interventions administered to critically ill patients.

Hospital malnutrition in northeast and southeast Asia: A systematic literature review

BACKGROUND & AIMS

Hospital malnutrition is a prevalent yet frequently under-recognised condition that is associated with adverse clinical and economic consequences. Systematic reviews from various regions of the world have provided regional estimates of the prevalence of malnutrition and the magnitude of the associated health and economic burden; however, a systematic assessment of the prevalence and consequences of hospital malnutrition in northeast and southeast Asia has not been conducted.

METHODS

We performed a systematic literature search for articles on hospital malnutrition in 11 Asian countries published in English between January 1, 1997 and January 15, 2018. Studies reporting data on the prevalence, clinical consequences, or economic impact of hospital malnutrition in an adult inpatient population with a sample size ≥30 were eligible for inclusion.

RESULTS

The literature search identified 3207 citations; of these, 92 studies (N = 62,280) met the criteria for inclusion. There was substantial variability in study populations and assessment methods; however, a majority of studies reported a malnutrition prevalence of >40%. Malnutrition was associated with an increase in clinical complications, mortality, length of hospitalisation, hospital readmissions, and healthcare costs.

CONCLUSIONS

Hospital malnutrition is a highly prevalent condition among hospitalised patients in northeast and southeast Asia. Additionally, poor nutritional status is associated with increased morbidity and mortality and increased healthcare costs. Further research aimed at improving the identification and proactive management of hospitalised patients at risk for malnutrition is necessary to improve patient outcomes and alleviate the burden on local healthcare budgets.

The Relationship between Serum Concentrations of Pro- and Anti-Inflammatory Cytokines and Nutritional Status in Patients with Traumatic Head Injury in the Intensive Care Unit

Background and objective: The aim of the present study was to examine the relationship between serum levels of pro-inflammatory cytokines (IL-6, IL-1β, and TNF-α) and anti-inflammatory cytokines (IL-10) measured once at the baseline with changes in nutritional status of patients with traumatic head injury (THI) assessed at three consecutive times (24 h after admission, day 6 and day 13) during hospital stay in the intensive care unit (ICU). Materials and Methods: Sixty-four patients with THI were recruited for the current study (over 10 months). The nutritional status of the patients was determined within 24 h after admission and on days 6 and 13, using actual body weight, body composition analysis, and anthropometric measurements. The APACHE II score and SOFA score were also assessed within 24 h of admission and on days 6 and 13 of patients staying in the ICU. Circulatory serum levels of cytokines (IL-6, IL-1β, TNF-α, and IL-10) were assessed once within 24 h of admission. Results: The current study found a significant reduction in BMI, FBM, LBM, MAUAC, and APM, of THI patients with high serum levels the cytokines, over the course of time from the baseline to day 7 and to day 13 in patients staying in the ICU (p < 0.001). It was also found that patients with low levels of some studied cytokines had significant improvement in their nutritional status and clinical outcomes in term of MAUAC, APM, APACHE II score and SOFA score (p < 0.001 to p < 0.01). Conclusion: THI patients who had high serum levels of studied cytokines were more prone to develop a reduction of nutritional status in terms of BMI, FBM, LBM MAUAC and APM over the course of time from patient admission until day 13 of ICU admission.

Evaluation of Blood Biomarkers Associated with Risk of Malnutrition in Older Adults: A Systematic Review and Meta-Analysis

Malnutrition is a common yet under-recognized problem in hospitalized patients. The aim of this paper was to systematically review and evaluate malnutrition biomarkers among order adults. Eligible studies were identified through Cochrane, PubMed and the ProQuest Dialog. A meta-regression was performed on concentrations of biomarkers according to malnutrition risks classified by validated nutrition assessment tools. A total of 111 studies were included, representing 52,911 participants (55% female, 72 ± 17 years old) from various clinical settings (hospital, community, care homes). The estimated BMI (p < 0.001) and concentrations of albumin (p < 0.001), hemoglobin (p < 0.001), total cholesterol (p < 0.001), prealbumin (p < 0.001) and total protein (p < 0.05) among subjects at high malnutrition risk by MNA were significantly lower than those without a risk. Similar results were observed for malnutrition identified by SGA and NRS-2002. A sensitivity analysis by including patients with acute illness showed that albumin and prealbumin concentrations were dramatically reduced, indicating that they must be carefully interpreted in acute care settings. This review showed that BMI, hemoglobin, and total cholesterol are useful biomarkers of malnutrition in older adults. The reference ranges and cut-offs may need to be updated to avoid underdiagnosis of malnutrition.

Jordanian Critical Care Nurses' Practices Regarding Enteral Nutrition

In Jordan, there is a gap in literature regarding nurses' practices of enteral nutrition. Thus, the purpose of this study was to assess nurses' practices regarding enteral nutrition of critically ill adult patients. A descriptive, cross-sectional design was used to collect data through self-reported questionnaires and descriptive analyses were used to display the results of the study. The results revealed that some aspects of enteral nutrition practices were consistent with the current best evidences such as initiation time of enteral nutrition and backrest elevation. On the contrary, some aspects showed variations and inconsistency with current best evidences such as the amount of high gastric residual volume and its management. Nurses' practices regarding enteral nutrition were not consistent with international guidelines. This inconsistency can predispose patients to underfeeding. Enhancement of research utilization is highly recommended as well as establishing evidence-based guidelines.

Investigating critical care nurses' perception regarding enteral nutrition

BACKGROUND

Evidences showed that nurses lack the needed knowledge to administer nutritional care. Besides, nutritional information was found to be incomplete in patients' record, and nurses' responsibilities regarding EN were not well understood. In Jordan, literature regarding nurses' perceptions of EN is scarce.

AIM

To investigate critical care nurses' perceptions regarding enteral nutrition (EN) of critically-ill adult patients.

METHODS

A descriptive, cross-sectional, comparative design was used to collect data from 151 Jordanian critical care nurses utilizing the Nurses' Perception of Enteral Nutrition Questionnaire.

RESULTS

Nurses in private hospitals scored the highest in regard to responsibility and support from documentation. Education, internet, and nursing school were the primary sources of EN knowledge. Besides, female nurses differ significantly from male nurses in regard to the perception of responsibility of EN.

CONCLUSION

Awareness of responsibility, supportive documentation system, and implementation of the current evidences of EN in the actual daily practices can be used to improve EN practices.
