Nutrition screening, assessment, and intervention practices for children with cancer in Aotearoa, New Zealand

OBJECTIVE

The purpose of this study was to investigate dietetic resources and current nutrition screening, assessment, and intervention practices in pediatric oncology centers in Aotearoa, New Zealand.

METHODS

A national survey of the two specialist treatment centers and 14 shared care centers that provide care to childhood cancer patients in Aotearoa, New Zealand, was conducted.

RESULTS

The two specialist treatment centers in Aotearoa, New Zealand, were the only centers with a dedicated dietetic oncology full-time equivalent resource; this full-time equivalent resource was devoted to inpatient care. Only 5 shared care centers (44%) had access to general pediatric dietetic support. Dietetic cover for outpatients or day-stay patients and use of standardized nutrition screening and assessment tools were limited. Weight and height were commonly measured, but there was inconsistency in the frequency and recording of measurements. Nutrition interventions, including nutrition education, oral nutrition support, enteral nutrition, and intravenous nutrition, were available within all centers but criteria for initiating support varied. Common barriers to providing nutrition interventions included staff resourcing and ad hoc referral pathways. Awareness of the relevance and clinical benefit of nutrition in pediatric oncology was low. Suggestions to improve nutrition screening, assessment, and intervention within Aotearoa, New Zealand, included the creation of standardized screening and referral criteria.

CONCLUSIONS

Resource limitations and lack of nutritional screening and assessment prevent adequate nutritional intervention for children with cancer in Aotearoa, New Zealand. Akin to other high-income countries, there is a need to harmonize the management of nutritional challenges in children with cancer. This study provides a first step in establishing an evidence base to help support efforts to address this need in Aotearoa, New Zealand.

Developing a nutrition screening tool for children with cystic fibrosis ages 0 to 2 years: Children with cystic fibrosis nutrition screening tool

BACKGROUND

For children with cystic fibrosis (CF), achieving and maintaining optimal growth by the age of 2 years is critical for future health outcomes. A standardized nutrition screening is needed to identify growth problems, enable timely interventions, and improve nutritional outcomes for children (0 to 2 years) with CF. The purpose of this study was to develop a nutrition screening tool for children (0 to 2 years) with CF to identify nutrition risk at every clinical encounter.

METHODS

A retrospective cross-sectional study was used to develop a nutrition screening tool to determine if nutrition interventions needed to change (at-risk) or continue (not at-risk). Retrospective data for pertinent nutrition factors were collected for 99 children attending an accredited CF clinic. The nutrition factors were compared to a dietitian assessment. A stepwise discriminant analysis determined weight-for-age (WFA) and weight-for-length (WFL) z-scores were significant. Then anthropometric data and corresponding dietitian assessment results were collected for children with CF attending two other accredited CF clinics (n = 29, n = 30). Discriminant analysis was used to determine sensitivity and specificity of the nutrition factors and to create a nutrition screening tool equation.

RESULTS

The nutrition screening model that included WFA z-score, LFA z-score, WFL z-score, and weight change velocity adequacy determined nutrition risk the best. The sensitivity was 89.7 %, specificity 83.2 %, NPV 93.3 %, and PPV 75.4 % for this model.

CONCLUSION

The nutrition screening tool equation developed in this study standardizes the process to identify children (0 to 2 years) with CF at nutrition risk. Further validation is needed.

Malnutrition screening tool and malnutrition universal screening tool as a predictors of prolonged hospital stay and hospital mortality: A cohort study

BACKGROUND & AIMS

Different nutrition screening tools have been proposed to screen inpatients, although, there is still no consensus regarding the reference method for identifying patients at nutritional risk. This retrospective cohort study aimed to evaluate the concurrent and predictive validity of the Malnutrition Screening Tool (MST) and Malnutrition Universal Screening Tool (MUST) to identify inpatients at nutritional risk.

METHODS

Data from electronic medical records were collected from adult and elderly inpatients in wards of a public tertiary hospital (Hospital de Clínicas de Porto Alegre, Brazil) over one year. Only the first nutritional evaluation was considered for each patient. GLIM criteria was used for malnutrition status (concurrent validity) and hospital stay length and mortality were outcomes to predictive validity.

RESULTS

A total of 5270 patients were included in this study. The mean patient age was 59 ± 16 years old, and 50.7% were males. More than 60% of the patients (65.8%) were admitted to a surgical unit, 63.8% had mild disease-related metabolic stress, 50.7% experienced prolonged hospital stays (more than ten days), and 1.9% of the patients died. Considering the availability of nutritional data, it was possible to perform nutritional screening of 98.1% of patients by MST and 96.7% of patients by MUST. A higher proportion of patients at risk were identified by MUST (53.6%) as compared to MST (21.3%; P < 0.001). MST had 89.9% of Specificity, 60.4% of PPV, 94.6% of NPV, and a moderate agreement with malnutrition by GLIM criteria (κ = 0.591; P < 0.001). A prolonged hospital stay was positively associated with the classification of nutritional risk based on both screening tools. Death was positively associated with nutritional risk by MST (hazard ratio [HR] 2.09; 95% confidence interval [CI] 1.37-3.16) and by MUST (HR 1.79; 95% CI 1.00-3.18) after adjustment based on sex, age, admission type (surgical or clinical), and disease-related metabolic stress.

CONCLUSIONS

MST may be good concurrent validity to malnutrition by GLIM criteria as compared to MUST. However, both risk nutritional tools were positively associated with predicting a prolonged hospital stay and mortality.

Three-Stage Nutrition Diagnosis for surgical patients at the perioperative period

Medical nutrition therapy has been widely applied in various diseases as a fundamental or even a first-line treatment. Patient who undergoes a disease state especially at the perioperative period can be much improved with the help of nutrition therapy. Precise nutrition diagnosis should be conducted before applying any nutrition therapy. Traditional malnutrition diagnostic process, however, is a two-stage process (nutrition screening and nutrition assessment) which cannot precisely assess nutritional status of surgical patients or the consequences of being malnourished. This article systematically introduced a new nutrition diagnostic process - Three-Stage Diagnosis (nutrition screening, nutrition assessment, and comprehensive evaluation) and discussed its applications during perioperative period.

A prospective epidemiological analysis of controlling nutritional status score with the poor functional outcomes in Chinese patients with haemorrhagic stroke

Nutritional Risk Screening index is a standard tool to assess nutritional risk, but epidemiological data are scarce on controlling nutritional status (CONUT) as a prognostic marker in acute haemorrhagic stroke (AHS). We aimed to explore whether the CONUT may predict a 3-month functional outcome in AHS. In total, 349 Chinese patients with incident AHS were consecutively recruited, and their malnutrition risks were determined using a high CONUT score of ≥ 2. The cohort patients were divided into high-CONUT (≥ 2) and low-CONUT (< 2) groups, and primary outcomes were a poor functional prognosis defined as the modified Rankin Scale (mRS) score of ≥ 3 at post-discharge for 3 months. Odds ratios (OR) with 95 % confidence intervals (CI) for the poor functional prognosis at post-discharge were estimated by using a logistic analysis with additional adjustments for unbalanced variables between the high-CONUT and low-CONUT groups. A total of 328 patients (60·38 ± 12·83 years; 66·77 % male) completed the mRS assessment at post-discharge for 3 months, with 172 patients at malnutrition risk at admission and 104 patients with a poor prognosis. The levels of total cholesterol and total lymphocyte counts were significantly lower in high-CONUT patients than low-CONUT patients (P = 0·012 and < 0·001, respectively). At 3-month post discharge, there was a greater risk for the poor outcome in the high-CONUT compared with the low-CONUT patients at admission (OR: 2·32, 95 % CI: 1·28, 4·17). High-CONUT scores independently predict a 3-month poor prognosis in AHS, which helps to identify those who need additional nutritional managements.

Applicability of the GLIM criteria for the diagnosis of malnutrition in older adults in the emergency ward: A pilot validation study

BACKGROUND & AIMS

Acutely ill older adults are at higher risk of malnutrition. This study aimed to explore the applicability and accuracy of the GLIM criteria to diagnose malnutrition in acutely ill older adults in the emergency ward (EW).

METHODS

We performed a retrospective secondary analysis, of an ongoing cohort study, in 165 participants over 65 years of age admitted to the EW of a Brazilian university hospital. Nutrition assessment included anthropometry, the Simplified Nutritional Assessment Questionnaire (SNAQ), the Malnutrition Screening Tool (MST), and the Mini-Nutritional Assessment (MNA). We diagnosed malnutrition using GLIM criteria, defined by the parallel presence of at least one phenotypic [nonvolitional weight loss (WL), low BMI, low muscle mass (MM)] and one etiologic criterion [reduced food intake or assimilation (RFI), disease burden/inflammation]. We used the receiver operating characteristic (ROC) curves and Cox and logistic regression for data analyses.

RESULTS

GLIM criteria, following the MNA-SF screening, classified 50.3% of participants as malnourished, 29.1% of them in a severe stage. Validation of the diagnosis using MNA-FF as a reference showed good accuracy (AUC = 0.84), and moderate sensitivity (76%) and specificity (75.1%). All phenotypic criteria combined with RFI showed the best metrics. Malnutrition showed a trend for an increased risk of transference to intensive care unit (OR = 2.08, 95% CI 0.99, 4.35), and severe malnutrition for in-hospital mortality (HR = 4.23, 95% CI 1.2, 14.9).

CONCLUSION

GLIM criteria, following MNA-SF screening, appear to be a feasible approach to diagnose malnutrition in acutely ill older adults in the EW. Nonvolitional WL combined with RFI or acute inflammation were the best components identified and are easily accessible, allowing their potential use in clinical practice.

Perioperative nutrition management for gastric cancer

Gastric cancer is one of the most frequently diagnosed and the leading cause of cancer death worldwide. Malnutrition is a substantial problem in patients with gastric cancer, associated with poor treatment tolerance and increased morbidity. It has also been recognized as an independent prognostic factor in individuals with cancer. Early detection of malnutrition and effective perioperative nutrition intervention play an important role in the treatment of gastric cancer. Nutrition screening and assessment are the first steps in nutrition management and provide a basis for further nutrition support. Several tools, including the Nutrition Risk Screening-2002 and Patient-Generated Subjective Global Assessment, have been developed for nutrition screening and assessment. Effective nutrition support can significantly improve nutritional and immune status, reduce the incidence of postoperative complications, and accelerate recovery. The aim of this review was to focus on preoperative nutrition risk screening and assessment, and perioperative nutrition support, which may serve as a framework of perioperative nutrition management for gastric cancer.

The validity of the global leadership initiative on malnutrition criteria for diagnosing malnutrition in critically ill patients with COVID-19: A prospective cohort study

BACKGROUND AND AIM

We conducted the present study to investigate the nutritional status of critically ill COVID-19 patients and validate the GLIM criteria with respect to the SGA.

METHODS

In this prospective cohort study, 109 ICU patients were assessed for malnutrition based on GLIM and SGA criteria. The relation between nutrition assessment tools and duration of hospitalization and mortality were also evaluated. The sensitivity and specificity of GLIM criteria concerning the detection of malnutrition was assessed based on the area under the curve.

RESULTS

Malnutrition, according to the SGA and GLIM criteria, was found in 68 (62.4%) and 66 (61.5%) of our subjects. There was an optimal agreement between the GLIM criteria and the SGA criteria regarding malnutrition diagnosis (K = 0.85, P < 0.001). The area under curve for the GLIM was stratified based on the SGA results and was 0.927 (95% CI: 0.868-0.985) with a sensitivity and specificity of 92% and 93%, respectively.

CONCLUSION

Malnutrition is frequently observed in critically ill COVID-19 patients. GLIM criteria is a valid tool and has a strong association with mortality and longer duration of ICU stay.

The validity of the Patient-Generated Subjective Global Assessment Short-form© in cancer patients undergoing chemotherapy

BACKGROUND & AIMS

The high prevalence of malnourished cancer patients highlights the importance of sensitive and specific tools for nutritional risk and status assessment screening, namely the Patient-Generated Subjective Global Assessment (PG-SGA®). This study aimed to assess whether the short-form version of the PG-SGA® (PG-SGA© SF) would be appropriate to identify the nutritional risk of patients when compared with the final global score of PG-SGA© (long-form version).

METHODS

This transversal and observational study comprised a convenience sample of cancer patients undergoing chemotherapy at the Champalimaud Clinical Centre between December 2016 and February 2018. Clinical data and anthropometric parameters were collected in order to apply PG-SGA® and PG-SGA© SF. The data was statistically analysed through SPSS version 22 (SPSS Inc, Chicago, IL, USA).

RESULTS

In this study 355 patients were enrolled and PG-SGA© SF results showed that 69.3% (n = 246) of the population presented at least one risk factor for malnourishment (Σ (box A) ≥1). Additionally, PG-SGA® revealed that 50% of patients (n = 177) have a risk of developing malnourishment or are already malnourished (B and C classification). The concordance of results showed to be high (coefficient k = 0.62; p < 0.001), meaning that PG-SGA SF© has a good sensibility (95%) and specificity (67%) for the identification of nutritional risk and assessment of nutritional status when compared with the complete version of PG-SGA©.

CONCLUSIONS

According to our results, PG-SGA© SF is a useful and sufficient tool, representing an easier and faster way to identify at-risk or malnourished patients.

Executive Summary of the 2020 Academy of Nutrition and Dietetics and National Kidney Foundation Clinical Practice Guideline for Nutrition in CKD

The 2020 update to KDOQI Clinical Practice Guidelines for Nutrition in chronic kidney disease (CKD) is a result of the collaboration between the National Kidney Foundation (NKF) and the Academy of Nutrition and Dietetics (Academy). The target population for this guideline is adults with stages 1 through 5 CKD who are not receiving dialysis, end-stage kidney disease including those on dialysis, and individuals with functional kidney transplant. The updated guideline includes 83 recommendations on important nutrition topics in CKD, including nutrition screening and assessment; medical nutrition therapy; dietary protein and energy intake; micronutrients; electrolytes; nutritional supplementation; and dietary patterns. Both Academy and Grading of Recommendations Assessment, Development and Evaluation (GRADE) approaches were used to assess quality of evidence and rate the recommendation statements. Guideline recommendations were the result of a comprehensive systematic review, clinical expertise, and considerations for individualized care.

Assessment of clinical practice procedures among Registered Dietitian Nutritionists for identifying feeding dysfunction in the pediatric population

BACKGROUND & AIMS

Feeding dysfunction is common in children. Efficient processes to identify and treat feeding dysfunction are not commonly known or used among healthcare practitioners. The aim of this study was to develop and validate a survey tool to assess current practice procedures used by Registered Dietitian Nutritionists (RDN) in identifying, diagnosing, and treating feeding dysfunction in children 0-18 years of age.

METHODS

A survey was developed and distributed to gather information on RDN practice procedures, prevalence of pediatric feeding dysfunction, identification of pediatric feeding dysfunction, and method of treatment used to address pediatric feeding dysfunction. Emails were sent to 4449 RDNs in United States. All participants were classified by the Commission on Dietetic Registration (CDR) as clinical dietitians. Distribution and frequency of survey responses were assessed, and in the case of qualitative questions, were categorized according to themes identified.

RESULTS

Responses of RDNs from 41 states completed 341 total surveys, 179 surveys were included in data analysis. Eighty percent of participants do not use a specific screening tool to identify feeding dysfunction. Results concerning feeding therapy strategies and terms used by RDNs to describe feeding dysfunction were highly varied or lacking. Increased inclusion of RDNs on interdisciplinary teams was indicated by 80% of participants. The majority of participants indicated they refer patients with feeding dysfunction to other practitioners instead of providing feeding therapy themselves.

CONCLUSIONS

Standardized screening, diagnostic, and treatment protocols regarding feeding dysfunction are needed to provide consistent and comprehensive care for the pediatric population. Use of these protocols among RDNs would enable them to improve feeding abilities in more patients earlier in individual child development.

High risk of disease-related malnutrition in gastroenterology outpatients

OBJECTIVE

Disease-related malnutrition (DRM) in hospitalized patients is known to have significant negative impact on clinical outcomes. Meanwhile, DRM in gastroenterology outpatients is scarcely investigated. The aim of this study was to investigate the prevalence of unintentional weight loss (UWL) and reduced food intake (RFI) as contributors to the risk of DRM in outpatients. Furthermore, the aim was to investigate if UWL may be used as initial screening for DRM, based on the correlation between UWL and RFI.

METHODS

All outpatients visiting the clinics for Medical and Surgery Gastroenterology, Aalborg University Hospital, Denmark, during 1 wk in September 2018, were invited to participate. Data regarding UWL within the past 3 mo, RFI the past week, and nutritional impact symptoms (NIS) were collected in this questionnaire-based cross-sectional study. Descriptive analysis, χ² test, and multiple logistic regression analysis were used for statistics.

RESULTS

Out of 348 eligible patients, 346 were included at the medical clinic (n = 170) and surgery clinic (n = 176). UWL occurred in 26%, with a mean weight loss of 7.1 kg (standard deviation [SD] 5.2), and 24% had RFI. A significantly increased risk of UWL was identified in patients with body mass index <18.5 kg/m² (odds ratio 6.1; confidence interval 2.0-18.7; P = 0.003). NIS were more common in the medical clinic. The main self-reported reasons for NIS affecting UWL were lack of appetite (15% versus 12%), pain (14% versus 8%), and nausea (12% versus 3%).

CONCLUSIONS

One in four outpatients experienced UWL to an extent that may have a significant negative impact on clinical outcome. A firm correlation was found between UWL and RFI. Thus, based on this superficial study, UWL may be used as initial screening for protein-energy malnutrition in the medical and surgery gastroenterology outpatient setting. The impact on clinical outcome and of early nutritional intervention in these settings need to be investigated.

Rationale and design of a randomised controlled trial investigating the effect of multidisciplinary nutritional rehabilitation for patients treated for head and neck cancer (the NUTRI-HAB trial)

Background

Eating problems frequently affect quality of life and physical, psychological and social function in patients treated for head and neck cancer (HNC). Residential rehabilitation programmes may ameliorate these adverse effects but are not indicated for all individuals. Systematic assessment of rehabilitation needs may optimise the use of resources while ensuring referral to rehabilitation for those in need. Yet, evidence lacks on which nutrition screening and assessment tools to use. The trial objectives are: 1) To test the effect of a multidisciplinary residential nutritional rehabilitation programme compared to standard care on the primary outcome body weight and secondary outcomes health-related quality of life, physical function and symptoms of anxiety and depression in patients curatively treated for HNC and 2) To test for correlations between participants’ development in outcome scores during their participation in the programme and their baseline scores in Nutritional Risk Screening 2002 (NRS 2002), the Scored Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF), and M. D. Anderson Dysphagia Inventory (MDADI) and to assess sensitivity, specificity and predictive values of the three tools in relation to a clinically relevant improvement in outcome scores.

Methods

In a randomised controlled trial, 72 patients treated for HNC recruited through a nationwide survey will be randomised to a multidisciplinary residential nutritional rehabilitation programme or to a wait-list control group. Data are collected at baseline, three and six months. Primary outcome is change in body weight, and secondary outcomes include changes in quality of life, physical function and symptoms of anxiety and depression. Potential correlations between intervention effect and baseline scores in NRS 2002, PG-SGA-SF and MDADI will be tested, and sensitivity, specificity and predictive values of the three tools in relation to a clinically relevant improvement in outcome scores will be assessed.

Discussion

This is the first randomised controlled trial to test the effect of a multidisciplinary residential nutritional rehabilitation programme in patients treated for HNC. Recruitment through a nationwide survey gives a unique possibility to describe the trial population and to identify potential selection bias. As the trial will explore the potential of different nutrition screening and assessment tools in the assessment of rehabilitation needs in patients treated for HNC, the trial will create knowledge about how selection and prioritisation of nutritional rehabilitation aimed at patients treated for HNC should be offered. The results may contribute to a better organisation and use of existing resources in benefit of patients treated for HNC.

Trial registration

The trial is registered by The Danish Data Protection Agency (registration 2012-58-0018, approval number 18/14847) and the Regional Committees on Health Research Ethics for Southern Denmark (journal number 20182000–165). ClinicalTrials.gov Identifier: NCT03909256. Registered April 9, 2019.

Comparison of nutritional screening and diagnostic tools in diagnosis of severe malnutrition in critically ill patients

RATIONALE

While various nutritional assessment tools have been proposed, consensus is lacking with respect to the most effective tool to identify severe malnutrition in critically ill patients.

METHODS

We conducted a retrospective study in an adult general intensive care unit (ICU) comparing four nutritional assessment tools: Nutrition Risk Screening (NRS), Nutrition Risk in Critically Ill (NUTRIC), and malnutrition criteria proposed by European Society of Clinical Nutrition and Metabolism (ESPEN) and American Society for Parenteral and Enteral Nutrition (ASPEN). These criteria were tested for their sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) in diagnosis of severe malnutrition, defined as Subjective Global Assessment (SGA) C.

RESULTS

Hospitalization records for 120 critically ill patients were analyzed. 60 (50%), 17 (14.2%) and 43 (35.8%) patients were classified as SGA A, B, and C, respectively. The sensitivity in diagnosis of severe malnutrition was 79.1%, 58.1%, 65.1%, and 65.1%, and specificity was 94.8%, 74.0%, 94.8%, and 98.7% for NRS, NUTRIC, ESPEN, and ASPEN, respectively. NRS, ESPEN, and ASPEN had higher PPV (89.5%, 87.5%, and 87.5%, respectively) and NPV (89%, 83%, and 83.5%, respectively) than NUTRIC (PPV 55.6% and NPV 76%). NUTRIC showed the highest correlation with mortality, but none of the tools retained their correlation with mortality after adjustment for potential confounding factors.

CONCLUSIONS

NRS showed the highest sensitivity and high specificity, PPV, and NPV. NUTRIC had least effective overall performance in diagnosis of severe malnutrition in an ICU setting. A larger population may be required to explore the association between mortality and these nutritional assessment tools.

GLIM criteria has fair sensitivity and specificity for diagnosing malnutrition when using SGA as comparator

BACKGROUND & AIMS

The Global Leadership Initiative on Malnutrition (GLIM) proposed a new framework for diagnosing malnutrition based on combinations of phenotypic and etiologic criteria. The aim of this study was to compare GLIM criteria to Subjective Global Assessment (SGA) judged to be the most validated standardized assessment of malnutrition.

METHODS

This is a retrospective analysis of variables extracted from a prospective cohort study assessing malnutrition at admission, in 18 Canadian hospitals. Based on the available parameters, GLIM was compared to SGA using the following combinations of one phenotypic and one etiologic criteria: A. weight loss and low intake; B. weight loss and high C-reactive protein (CRP); C. low body mass index (BMI) and low intake; D. low BMI, high CRP. Data were not available for fat-free mass. Since all patients had acute or chronic active disease as per GLIM etiologic criterion, CRP was used as a more specific measure to define inflammation. Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated. Data are expressed as mean and Clopper-Pearson exact 95% confidence interval (CI).

RESULTS

From 1022 patients in the original dataset, 784 had all considered parameters with a prevalence of malnutrition (SGA B or C) of 45.15% (CI 41.60, 48.70), where severe malnutrition (SGA C) was 11.73% (CI 9.57, 14.20). Using the available GLIM parameters with the above combinations of two-criteria, the prevalence of malnutrition was 33.29% (CI 30.00, 36.71) and severe malnutrition was 19.77% (CI 17.00, 22.70). For all criteria combinations of GLIM together versus SGA, sensitivity was 61.30% (CI 56.0, 66.4), specificity was 89.77% (CI 86.5, 92.5) and PPV was 83.14% (CI 78.0, 87.5) while NPV was 73.80 (CI 69.8, 77.5). Sensitivity was improved when only SGA C for severe malnutrition was used as the criterion (82.61%; CI 73.3, 89.7) but PPV was greatly reduced (29.12%; CI 23.7, 35.0). Similarly, when using GLIM criteria for severe malnutrition only, sensitivity improved (76.09%; CI 66.1, 84.4). Any two criteria combinations of GLIM had much poorer sensitivity with the highest being weight loss + high CRP (46.33%) with a specificity of 93.02% (PPV: 84.54%; NPV: 67.80%), while the combination of low BMI + low intake had the highest specificity (98.84%) but with a sensitivity of 15.54% (PPV 91.67%; NPV: 58.70%).

CONCLUSIONS

Based on the CMTF dataset and using SGA as the most validated tool for diagnosing malnutrition, the two criteria combinations used for GLIM in the present study had fair criterion validity for the diagnosis of malnutrition, regardless of severity status. The best combinations were weight loss and high CRP or weight loss and low intake, both having high specificity at diagnosing malnutrition but unacceptably low sensitivity, and thus were considered poor. There may be potential for the full framework to be used to diagnose malnutrition, but individual combinations of two criteria when used exclusively will miss malnourished patients, as defined by SGA.

Feasibility of using the "modified NUTrition Risk In the Critically ill" nutritional risk screening tool to identify nutritionally at-risk patients in an Australian intensive care unit

BACKGROUND

The modified NUTrition Risk In the Critically ill (mNUTRIC) score has been demonstrated to accurately quantify the risk of negative patient outcomes and discriminate which patients will benefit the most from nutrition intervention in an intensive care unit (ICU) setting. Calculation of an mNUTRIC score, however, may be time-intensive and unable to be performed within available resources. This may prevent high-risk patients from being identified and reviewed by a dietitian.

OBJECTIVES

The purpose of this study was to assess the feasibility of using the mNUTRIC tool to screen for patients at increased nutrition risk and to determine the proportion of those high-risk patients who were reviewed by a dietitian.

SUBJECTS/METHODS

A retrospective observational study of 260 critically ill patients was conducted between 01/01/2017 and 30/05/2017 in a 20-bed Australian tertiary ICU. Participants included all adults admitted to the ICU for more than 72 h. Feasible implementation was defined as calculating an mNUTRIC score in <5 min per patient where all data were available for >90% of patients.

RESULTS

A median time of 4 min and 54 s (interquartile range: 4.3-5.6 min) was required to calculate each mNUTRIC score, with 96% of scores calculated in <10 min. Data were available to calculate mNUTRIC scores for 93% (241/260) of patients. The mNUTRIC tool identified 81 patients at high nutrition risk, 44% (36/81) of whom were not reviewed by a dietitian. There were 21 high-risk patients who were purposefully excluded from dietetic review for various clinical reasons, leaving 15 high-risk patients (19%) who were not reviewed by a dietitian.

CONCLUSIONS

Implementation of the mNUTRIC tool was not feasible in our ICU, given the set dietetic resources (0.6 full-time equivalent). Shared responsibility of nutrition screening or automating the calculation may be possible solutions to increase feasibility of mNUTRIC screening.

Similar health economic outcomes in low-risk and high-risk malnourished inpatients as screened by the Malnutrition Screening Tool after delivery of oral nutritional supplements

OBJECTIVE

The aim of this study was to determine whether modified low- and high-risk Malnutrition Screening Tool (MST) scores (2 versus >2, respectively) were independently predictive of health economic outcomes.

METHODS

We analyzed data from a recent nutrition-based quality improvement program (QIP) that prescribed daily oral nutritional supplements for all hospitalized adults at risk for malnutrition. In the original study, an electronic medical records-based MST was administered at the time of admission, and patients were classified as "low risk" or "high risk" for malnutrition based on MST scores (2 versus ≥2). We compared health economic outcomes for patients at low or high risk for malnutrition based on a modified score (MST = 2 versus >2, respectively), looking for between-group differences in length of stay (LOS) and unplanned 30-d readmissions. Analyses were additionally stratified by age (<65 versus ≥65 y of age).

RESULTS

Of the 1269 patients enrolled in the QIP, 413 (32.5%) had MST of 2 and 856 (67.5%) had MST >2. Mean LOS was 5.19 d (±4.78) for patients with MST 2 and 4.49 d (±4.69) with MST >2 (non-statistically significant between-group difference; P = 0.277). There were no significant differences in unplanned 30-d readmission rates (14% for low-risk and 17.1% for high-risk patients; P = 0.171). These findings remained statistically insignificant when the low- and high-risk MST score groups were further stratified by age.

CONCLUSIONS

Outcomes of hospitalized patients with MST 2 were not significantly different from those with an MST >2. This suggests that patients at both lower and higher risk for malnutrition (based on MST scores of 2 versus ≥3) were similar in terms of LOS and 30-d readmission rates. To avoid overlooking cases of malnutrition risk, the validated cutoff scores for the MST should be consistently implemented. Training that is consistent with the validated MST is recommended rather than attempting to reduce the case burden by "raising the bar" and attempting to classify patients with an MST = 2 as "low risk."

Nutrition-Related Outcomes for Autologous Stem Cell Transplantation Patients

INTRODUCTION

Autologous stem cell transplantation (ASCT) patients are at risk for malnutrition before transplantation admission as well as malnutrition acquired during their transplantation admission.

PATIENTS AND METHODS

In this retrospective, observational study we examined data related to consecutive adults (n = 330) admitted for ASCT between 2014 and 2016 at the Hospital of the University of Pennsylvania. Malnutrition risk on admission (identified by the Malnutrition Screening Tool) and transplantation-associated weight loss were analyzed for independent associations with hospital length of stay, nosocomial infection, intensive care unit transfer, deconditioning, time to platelet and neutrophil engraftment, 30-day readmission, and 1-year mortality.

RESULTS

Adults with high malnutrition risk (n = 60) had a longer median hospital stay (P = .004), longer median time to platelet engraftment (P = .022), increased nosocomial infections (P = .047), and increased 1-year mortality (P = .036). Adults with high transplantation-associated weight loss (n = 100) experienced longer hospital stays (P < .001) and more intensive care unit transfers (P = .001). Outcomes for deconditioning, time to neutrophil engraftment, and 30-day readmission did not differ significantly on the basis of nutrition risk or weight loss.

CONCLUSION

Further research is needed to determine whether early nutrition intervention would improve these outcomes.

Perioperative nutrition assessment in musculoskeletal trauma patients: Dietitian evaluation is superior to serum chemistries or modified screening questionnaire for risk stratification

INTRODUCTION

Malnutrition is a potentially modifiable risk factor associated with increased hospital charges, major wound complication, and fracture non-union after orthopaedic surgery. The goal of this study was to examine the relationship between three nutrition screening tools and postoperative complications in patients undergoing acute fracture fixation.

METHODS

Patients aged 18 or older undergoing acute operative fracture fixation at a Level I academic trauma center were screened upon admission using a malnutrition screening questionnaire (MSQ), and classified as low-, moderate- or high risk. Patients at moderate-to-high risk were assessed for clinical malnutrition by dietitian. Serum albumin, transferrin, total lymphocyte count, and 25(OH) Vitamin D were measured preoperatively. Primary outcome measures included twelve-month postoperative surgical and medical complications obtained by retrospective chart review.

RESULTS

Of 373 patients, 17% were moderate-to-high risk of malnutrition by MSQ. Clinical malnutrition was diagnosed by dietitian in 4.3% of patients assessed. Nearly half of all subjects had deficiency in one or more serum biomarkers. Cost of biomarker assays was $624 per patient. Medical or surgical complications occurred in 19% of patients. Dietitian diagnosed malnutrition (clinical malnutrition) was the strongest predictor of complication (OR 3.49, p = 0.017). Hypoalbuminemia was also associated with increased complication risk (OR 1.79, p = 0.045). MSQ score was not correlated with postoperative complication.

CONCLUSIONS

Among the examined malnutrition screening tools, clinical malnutrition had the strongest association with postoperative complication. Hypoalbuminemia was associated with increased odds of complication, however there was a large false positive rate with all tested serum chemistries and high associated hospital charges compared to dietitian assessment. MSQ was a poor predictor of malnutrition and clinical outcome. Dietetic assessment is advised for orthopaedic trauma patients.

Evaluating the concurrent validity of body mass index (BMI) in the identification of malnutrition in older hospital inpatients

BACKGROUND

Nutrition screening and assessment tools often include body mass index (BMI) as a component in identifying malnutrition risk. However, rising obesity levels will impact on the relevancy and applicability of BMI cut-off points which may require re-evaluation. This study aimed to explore the relationship between commonly applied BMI cut-offs and diagnosed malnutrition.

METHODS

Data (age, gender, BMI and Subjective Global Assessment (SGA) ratings) were analysed for 1152 inpatients aged ≥65 years across annual malnutrition audits (2011-2015). The receiver operation characteristic (ROC) curve analysed the optimal BMI cut-off for malnutrition and concurrent validity of commonly applied BMI cut-offs in nutritional screening and assessment tools.

RESULTS

Malnutrition prevalence was 36.0% (n = 372) using SGA criteria (not malnourished, moderate or severe malnutrition). Median age was 78.7 (IQR 72-85) years, median BMI 25.4 (IQR 21.8-29.7) kg/m²; 52.1% male and 51.2% overweight/obese. ROC analysis identified an optimal BMI cut-off of <26 kg/m², 80.8% sensitivity and 61.5% specificity (AUC 0.802, 95% CI 0.773, 0.830; p < 0.0001). Commonly applied BMI cut-offs (between 18.5 and 23 kg/m²) failed to meet the alpha-priori requirement of 80% sensitivity and 60% specificity. However, BMI <23 kg/m² had the highest agreement (κ = 0.458) with malnutrition diagnosed using the SGA.

CONCLUSIONS

Both malnutrition and overweight/obesity are common in older inpatients. Continuing increases in the prevalence of overweight and obesity will impact on the sensitivity of BMI as a screening component for malnutrition risk. The current study suggests tools developed over a decade ago may need to be revisited in future.

A new renal inpatient nutrition screening tool (Renal iNUT): a multicenter validation study

BACKGROUND

Screening of patients with renal disease for malnutrition risk on hospital admission provides an opportunity to improve prognosis. This study aimed to assess the validity and reliability of the Renal iNUT, a novel renal-specific inpatient nutrition screening tool.

METHODS

Adult inpatient admissions to three renal units were screened using the Renal Inpatient Nutrition Screening Tool (iNUT) and the generic Malnutrition Universal Screening Tool (MUST) and compared against nutritional status using Subjective Global Assessment (SGA) as the standard. Construct validity was assessed by Handgrip Strength (HGS), reliability by repeated iNUT administration and nurse opinion by questionnaire.

RESULTS

Of 141 admissions, 45% were malnourished (SGA score B or C). Using iNUT, 49% patients had increased malnutrition risk (score ≥1), 35.5% requiring dietetic referral (score ≥2). MUST indicated 20% at increased malnutrition risk and dietetic referral in 7%. iNUT was more sensitive than MUST in identifying increased malnutrition risk (92.1% vs 44.4%) and dietetic referral (69.8% vs 15.9%). Specificity of iNUT for increased risk was 82.1% and 92.3% for dietetic referral. 47% patients had sarcopenic-range HGS, with significant difference between iNUT score ≥2 and 0 (p < 0.001). iNUT reliability assessed by kappa was 0.74 (95% CI, 0.58 to 0.9), indicating substantial agreement. Nurse evaluation (n = 71) was highly favorable.

CONCLUSIONS

The Renal iNUT is a valid and reliable nutrition screening tool when used by nurses admitting patients to specialist renal wards. In comparison with MUST, use of iNUT is likely to improve the identification of malnourished patients for nutritional intervention and dietetic referral.

Nutritional Therapy in Gastrointestinal Cancers

Malnutrition is the most frequent nutritional disorder in patients with gastrointestinal cancer and is associated with cachexia syndrome, worsening of prognosis, and shortened survival rate. Early nutrition screening, assessment, and intervention are able to favorably modify the clinical evolution of affected patients. The adequate provision of nutritional requirements has been associated with improvement of immunologic status, and avoidance of further complications related to poor nutritional status, surgical treatment, and anticancer therapy. In malnourished patients, the supplementation of perioperative immunonutrition might contribute to fewer infectious and noninfectious complications, shorter length of hospitalization, and improved wound healing.

Update on the Integrated Nutrition Pathway for Acute Care (INPAC): post implementation tailoring and toolkit to support practice improvements

The Integrated Nutrition Pathway for Acute Care (INPAC) is an evidence and consensus based pathway developed to guide health care professionals in the prevention, detection, and treatment of malnutrition in medical and surgical patients. From 2015 to 2017, the More-2-Eat implementation project (M2E) used a participatory action research approach to determine the feasibility, and evaluate the implementation of INPAC in 5 hospital units across Canada. Based on the findings of M2E and consensus with M2E stakeholders, updates have been made to INPAC to enhance feasibility in Canadian hospitals. The learnings from M2E have been converted into an online toolkit that outlines how to implement the key steps within INPAC. The aim of this short report is to highlight the updated version of INPAC, and introduce the implementation toolkit that was used to support practice improvements towards this standard.

Assessment of perioperative nutrition practices and attitudes-A national survey of colorectal and GI surgical oncology programs

BACKGROUND

Implementation of evidence-based peri-operative nutrition in the U.S. is poorly described and hypothesized to be suboptimal. This study broadly describes practices and attitudes regarding nutrition screening/intervention in U.S. gastrointestinal and oncologic surgeons.

METHODS

Nationwide nutritional practice survey of GI/Oncologic surgical faculty.

RESULTS

Program response rates were 57% and 81% for colorectal and oncology fellowships, respectively. Only 38% had formal nutritional screening processes in place. Average estimated percent of patients malnourished, receiving nutritional screening, and receiving nutritional supplementation preoperatively were 28%, 43%, and 21%, respectively. University-affiliation (p = 0.0371) and a formal screening process (p = 0.0312) predicted higher preoperative nutritional screening rates. Controversy existed regarding routine use of perioperative immunonutrition, but strong consensus emerged that lack of awareness regarding positive data for immunonutrition impedes usage.

CONCLUSION

U.S. surgeons recognize importance of perioperative nutritional screening and benefits of basic nutrition therapy. However, limited formal nutrition screening programs currently exist indicating a significant need for implementation of nutrition screening and basic nutrition intervention. Further work on education, implementation and identifying clinical research needs for immunonutrition interventions is also vitally needed.

SUMMARY

This study broadly describes nutritional practices and attitudes of gastrointestinal and oncologic surgeons across the U.S. Surgeons recognize both the importance of proper perioperative surgical nutritional support and the potential value to their practice in terms of outcomes, but this study confirms poor implementation of evidence-based nutrition practices in GI and oncologic surgery programs. This study describes a significant opportunity to capitalize on current favorable surgeon beliefs (and positive published data) regarding the benefit of perioperative nutrition to improve surgical nutrition practice and patient outcomes in the U.S.

Serum Albumin and Prealbumin in Calorically Restricted, Nondiseased Individuals: A Systematic Review

PURPOSE

Undernutrition is often suspected in patients when serum albumin or prealbumin levels are low. We asked whether these measures are indeed low in undernourished people if no inflammatory illness is present.

METHODS

We did a systematic review to identify otherwise healthy subjects who were severely nutrient-deprived due to poor access to food or unwillingness to eat. We excluded children and pregnant women. We tabulated available measures of nutrient intake, anthropometry, serum albumin and prealbumin, and, when available, changes in these measures during nutritional intervention.

RESULTS

In otherwise healthy subjects, serum albumin and prealbumin levels remained normal despite marked nutrient deprivation until the extremes of starvation, that is, body mass index <12 or more than 6 weeks of starvation.

CONCLUSIONS

In these otherwise healthy subjects, serum albumin and prealbumin levels are not "markers of nutritional status." The "markers" failed to identify subjects with severe protein-calorie malnutrition until extreme starvation. That is, they failed to identify healthy individuals who would benefit from nutrition support, becoming abnormal only when starvation was already obvious. In contrast, serum albumin and prealbumin levels are known to fall promptly with injury or illness regardless of nutrient intake. They are negative acute-phase reactants. When these measures are low in sick patients, this cannot be assumed to reflect nutritional deprivation. Decisions about nutrition support should be based on evidence of meaningful benefit from this treatment rather than on assessment of "nutritional markers."

Potential barriers to effective MUST implementation

The Malnutrition Universal Screening Tool (MUST) is frequently cited as a simple screening tool for malnutrition. However, anecdotally, it seems that not all staff find it simple to use. If staff do not find MUST simple to complete, then screening is less likely to be completed accurately. Accurate completion of MUST is essential for malnutrition to be identified and treated, otherwise the nutritional needs of patients with unrecognised malnutrition may be neglected. The use of simplified versions of body mass index score, weight loss score and ulna-length charts together with ongoing training and support may help to improve accurate MUST completion. Audit of MUST completion must consider the accuracy of completion rather than completion alone. Therefore, those auditing MUST completion require a good understanding of the tool. This article draws on the author's own significant experience with applying the MUST tool and synthesises this with evidence from the literature to demonstrate the potential barriers to effective MUST implementation.

Nutritional screening: a community dietitian's perspective

Malnutrition in the UK is well documented and highlighted by the British Association of Parenteral and Enteral Nutrition, who advocate the use of a screening tool to facilitate the identification and subsequent management of undernutrition. Nurses are ideally placed to support this process, but their role has many conflicting priorities. For nurses working in the community, there also exists the problem of identifying those who are at risk of undernutrition but remain unknown to nursing services. This article provides a review of malnutrition and nutrition screening and aims to promote a pragmatic approach to the identification and management of undernutrition in the community. The article concludes with a brief review of current opportunities for improving nutritional care in the community.
