Nutrition Support Teams: A Systematic Review

Nutrition Assessment and Education of Patients with Heart Failure by Cardiologists

Although nutritional assessment and education are important for hospitalized patients with heart failure, the extent of their implementation in real-world clinical practice is unknown. Therefore, this study aimed to investigate the evaluation and management of nutrition during hospitalization for heart failure using a questionnaire survey for cardiologists.In this cross-sectional multicenter survey, 147 cardiologists from 32 institutions completed a web-based questionnaire (response rate, 95%).The survey showed that 78.2% of the respondents performed a nutritional assessment for hospitalized patients, whereas 38.3% used objective tools. In contrast, only 9.5% of the respondents evaluated the presence or absence of cardiac cachexia. Most respondents (89.8%) reported providing nutritional education to their patients before hospital discharge. However, compared with the number of respondents who provided information on sodium (97.0%) and water (63.6%) restrictions, a limited number of respondents provided guidance on optimal protein (20.5%) and micronutrient (9.1%) intake as part of the nutritional education. Less than 50% of the respondents provided guidance on optimal calorie intake (43.2%) and ideal body weight (34.8%) as a part of the nutritional education for patients identified as malnourished.Although nutritional assessment is widely performed for hospitalized patients with heart failure, most assessments are subjective rather than objective. Nutritional education, frequently provided before hospital discharge, is limited to information on water or salt intake restrictions. Therefore, more comprehensive and individualized nutritional assessments and counselling with a scientific basis are required.

Best evidence summary for prevention and management of enteral feeding intolerance in critically ill patients

AIM

To evaluate and summarize the evidence for prevention and management of enteral feeding intolerance in critically ill patients and provide reference for clinical practice.

DESIGN

This study was an evidence summary followed by the evidence summary reporting standard of Fudan University Center for Evidence-based Nursing.

METHODS

Current literatures were systematically searched for the best evidence for prevention and management of enteral feeding intolerance in critically ill patients. Literature types included clinical guidelines, best practice information sheets, expert consensuses, systematic reviews, evidence summaries and cohort studies.

DATA SOURCES

UpToDate, BMJ Best Practice, Joanna Briggs Institute, Guidelines International Network, National Institute for Health and Care Excellence, Registered Nurses Association of Ontario, Scottish Intercollegiate Guidelines Network, the Cochrane Library, Embase, PubMed, Sinomed, Web of Science, Yi Maitong Guidelines Network, DynaMed, MEDLINE, CNKI, WanFang database, Chinese Medical Journal Full-text Database, European Society for Clinical Nutrition and Metabolism website, the American Society for Parenteral and Enteral Nutrition website were searched from January 2012 to April 2023.

RESULTS

We finally identified 18 articles that had high-quality results. We summarized the 24 pieces of best evidence from these articles, covering five aspects: screening and assessment of the risk of enteral nutritional tolerance; formulation of enteral nutrition preparations; enteral nutritional feeding implementation; feeding intolerance symptom prevention and management; and multidisciplinary management. Of these pieces of evidence, 19 were 'strong' and 5 were 'weak', 7 pieces of evidence were recommended in level one and 4 pieces of evidence were recommended in level two.

CONCLUSION

The following 24 pieces of evidence for prevention and management of enteral feeding intolerance in critically ill patients were finally recommended. However, as these evidences came from different countries, relevant factors such as the clinical environment should be evaluated before application. Future studies should focus on more specific symptoms of feeding intolerance and more targeted prevention design applications.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

The clinical medical staffs are recommended to take evidence-based recommendations for the implementation of standardized enteral nutrition to improve patient outcomes and decrease gastrointestinal intolerance in critically ill patients.

IMPACT

The management of enteral nutrition feeding intolerance has always been a challenge and difficulty in critically ill patients. This study summarizes 24 pieces of the best evidence for prevention and management of enteral nutrition feeding intolerance in critically ill patients. Following and implementing these 24 pieces of evidence is beneficial to the prevention and management of feeding intolerance in clinical practice. The 24 pieces of evidence include five aspects, including screening and assessment of the risk of enteral nutritional tolerance, formulation of enteral nutrition preparations, enteral nutritional feeding implementation, feeding intolerance symptom prevention and management and multidisciplinary management. These five aspects constitute a good implementation process. Screening and assessment of enteral nutritional tolerance throughout intervention are important guarantees for developing a feasible nutrition program in critically ill patients. This study will be benefit to global medical workers in the nutritional management of critically ill patients.

Parenteral nutrition-related complications in older patients with acute intestinal failure: A descriptive cohort study

INTRODUCTION

Reported outcomes for parenteral nutrition (PN)-related complications in older adult patients with acute intestinal failure who are receiving PN in the acute hospital setting are limited. Our study aims to compare PN-related complications between older and younger adult patients.

METHODS

A retrospective descriptive study of inpatients who were administered PN from January 1, 2019, to December 31, 2019, was performed. Patients were categorized into older (≥65 years old) and younger (<65 years old) adult groups.

RESULTS

Two hundred thirty-five patients were included. There were 103 patients in the older adult group (mean age: 73.9 [SD: 6.9] years) and 132 patients in the younger adult group (mean age: 52.4 [SD: 12.5] years). There was a significantly higher Charlson Comorbidity Index score and lower Karnofsky score in the older adult group. The older adult group received significantly lower total energy (20.8 [SD: 7.8] vs 22.8 [SD: 6.3] kcal/kg/day), dextrose (3.1 [SD: 1.4] vs 3.6 [SD: 1.4] g/kg/day), and protein (1.1 [SD: 0.4] vs 1.2 [SD: 0.3] g/kg/day) than the younger group received. The mean length of stay was significantly shorter in the older adult group (35.9 [SD: 21.3] vs 59.8 [SD: 55.3]; P < 0.05). There was no significant difference in PN-related complications and clinical outcomes (catheter-related bloodstream infections, hypoglycemia or hyperglycemia, fluid overload, or inpatient mortality) between the two groups.

CONCLUSION

Despite more comorbidities in the older adult, the usage of PN in older adult patients with acute intestinal failure was associated with neither an increased rate of PN-related complications nor worse clinical outcomes when compared with that of younger patients.

Factors affecting target caloric achievement and calorie intake improvement: the nutrition support team's role

Background

The nutrition support team (NST) works to improve malnutrition in hospitalized patients, and its role is expanding as more hospitals adopt NST. This study aimed to identify the clinical characteristics of NST-referred patients admitted to a tertiary hospital. The study focused on two groups: those who achieved the target calories, approximately 75% or more of their caloric needs relative to their body weight regardless of the period after the first NST referral, and those who improved their calorie intake 1 week after NST therapy. This study also analyzed the important factors affecting the achievement of target calorie intake and improvement in calorie intake to discover the focus of future NST therapy.

Methods

This study examined 1,171 adult patients (aged ≥18 years) who were referred to the NST from all the departments within a tertiary hospital at least twice, with a minimum one-week interval between referrals, between January 1, 2019, and December 31, 2020. The study participants consisted of patients receiving <75% of their required caloric intake at the time of their first NST referral. Patients were categorized and compared according to whether they achieved their target calorie intake regardless of the period after the first NST referral and whether they improved their calorie intake 1 week after the NST therapy. We then identified factors affecting target caloric achievement and improvement in calorie intake.

Results

The group that achieved the target calorie intake had a lower proportion of neuro department patients (31.3%), a higher proportion of patients receiving intensive care unit (ICU) care (31.9%), and a longer ICU stay (p < 0.001) than the group that did not achieve the target calorie intake. Neuro department admission negatively affected target caloric achievement [adjusted odds ratio (aOR) = 0.305, 95% confidence interval (CI) = 0.150-0.617], whereas the length of ICU stay positively affected target caloric achievement (aOR = 1.025, 95% CI = 1.007-1.043). The proportion of neuro department patients was also low (42.5%) in the group with improved calorie intake 1 week after NST therapy. Neuro department admission was a negative factor (aOR = 0.376, 95% CI = 0.264-0.537) affecting the improvement in calorie intake.

Conclusions

NST therapy significantly improved clinical outcomes for inpatients at nutritional risk. Because achieving target calories and improving calorie intake in neuro department patients is difficult, it is necessary to actively refer them to NST to achieve the target calories and improve calorie intake. Furthermore, because a longer ICU stay positively affects target calorie achievement, the system for ICU nutrition therapy should be expanded and implemented for general-ward patients, including neurological patients.

Accreditation of nutrition support teams: A new initiative by the Turkish Society of Clinical Enteral & Parenteral Nutrition

OBJECTIVES

Accreditation is a process to evaluate compliance of an institution or organization with predetermined performance standards, focusing on achieving continuous improvement strategies and optimal quality standards and motivating the accredited organization to do so. There is no established accreditation program for nutrition support teams (NSTs) at national and international levels. In order to increase the standards of NSTs, developing an accreditation program is being planned by the Turkish Society of Clinical Enteral & Parenteral Nutrition (KEPAN).

METHODS

Accreditation standards were developed by a study group under the organization of KEPAN. Minimum standards for composition, qualifications, physical requirements, workflow charts, medical records, and both patient and health care providers' safety measures in NSTs were specified. These standards were uploaded to a computer program, and the necessary infrastructure for a web-based management of accreditation processes was developed.

RESULTS

An organization applying for accreditation should fill in the application form on KEPAN website electronically. Eligibility criteria for accreditation include number of NST members, physical environment, patient monitoring requirements, research, and training. A total of 22 standards are surveyed under 13 sections. These standards contain 61 criteria. To be accredited, each of 22 standards must score >70 and each of 13 sections must score >80.

CONCLUSIONS

In order to increase the quality of nutritional care and improve patient outcomes, an accreditation program has been developed. This program principally sets the basic standards, organizational scheme, and responsibilities of NSTs.

Nutrition Therapy by Nutrition Support Team: A Comparison of Multi-Chamber Bag and Customized Parenteral Nutrition in Hospitalized Patients

This study aimed to investigate the activity of a nutrition support team (NST) and the trends of multi-chamber bag (MCB) and customized parenteral nutrition (PN) with NST consultations in South Korea. Data were obtained from the National Inpatient Sample Cohort between 2015 and 2020. Three datasets were constructed for NST consultation, MCB-PN product prescriptions, and aseptic preparation of total PN. The intersections of the NST consultation and each PN dataset were compiled into MCB-PN with NST or customized PN with a NST sub-dataset, respectively. Using personal identifiers, the patients' characteristics were evaluated in the NST cohort. A total of 91,384 reimbursements and 70,665 patients were included. The NST activity had increased by more than 50% over 6 years. Approximately 70% and 11%, respectively, of the NST cohort were classified into two subgroups: MCB-PN with NST (M-NST) and customized PN with NST (C-NST). M-NST had many elderly patients with cancer and showed a higher in-hospital mortality than C-NST (12.6% vs. 9.5%). C-NST included a larger number of patients under the age of 5 years, and the hospitalization period was more extended than M-NST (26.2 vs. 21.2 days). The present study showed that NST activities and the proportion of PN with NST consultation are gradually increasing in South Korea.

Nutrition support teams: Institution, evolution, and innovation

The historical institution, evolution, and innovations of nutrition support teams (NSTs) over the past six decades are presented. Focused aspects of the transition to transdisciplinary and patient-centered care, NST membership, leadership, and the future of NSTs are further discussed. NSTs were instituted to address the need for the safe implementation and management of parenteral nutrition, developed in the late 1960s, which requires the expertise of individuals working collaboratively in a multidisciplinary fashion. In 1976, the American Society for Parenteral and Enteral Nutrition (ASPEN) was established using the multidisciplinary model. In 1983, the United States established the inpatient prospective payment system with associated diagnosis-related groupings, which altered the provision of nutrition support in hospitals with funded NSTs. The number of funded NSTs has waxed and waned since; yet hospitals and healthcare have adapted, as additional education and experience grew, primarily through ASPEN's efforts. Nutrition support was not administered in some instances by the "core of four" (physician, nurse, dietitian, pharmacist). The functions may be carried out by a member of the core of four not associated with the parent discipline, in accordance with licensure/privileging. This cross-functioning has evolved into the adaptation of the concept of transdisciplinarity, emphasizing function over form, supported and enhanced by "top-of-license" practice. In some institutions, nutrition support has been incorporated into other healthcare teams. Future innovations will assist NSTs in providing the right nutrition support for the right patient in the right way at the right time, recognizing that nutrition care is a human right.

Chinese expert consensus on prevention and intervention for the elderly with malnutrition (2022)

Malnutrition is a state of altered body composition and body cell mass due to inadequate intake or utilization of energy or nutrients, leading to physical and mental dysfunction and impaired clinical outcomes. As one of the most common geriatric syndromes, malnutrition in the elderly is a significant risk factor for poor clinical outcomes, causing a massive burden on medical resources and society. The risk factors for malnutrition in the elderly are diverse and include demographics, chronic diseases, and psychosocial factors. Presently, recommendations for the prevention and intervention of malnutrition in the elderly are not clear or consistent in China. This consensus is based on the latest global evidence and multiregional clinical experience in China, which aims to standardize the prevention and intervention of malnutrition in the elderly in China and improve the efficacy of clinical practice and the prognosis of elderly patients.

Management of Malnutrition Based on Multidisciplinary Team Decision-Making in Chinese Older Adults (3M Study): A Prospective, Multicenter, Randomized, Controlled Study Protocol

Background

In hospital settings, malnutrition affects 30-50% of aged inpatients and is related to a higher risk of hospital complications and death. This study aims to demonstrate the effectiveness of a tailored optimum nutritional therapy in malnourished, elderly inpatients based on multidisciplinary team recommendations in hopes of decreasing the incidence of deleterious clinical outcomes.

Methods and Design

This trial will be a multicenter, open-label, randomized control trial conducted in the geriatric wards of at least five hospitals in five different regions. We aim to include 500 inpatients over the age of 60 with or at risk of malnutrition based on a Mini Nutritional Assessment Short-Form (MNA-SF) score of ≤ 11 points and the Global Leadership Initiative on Malnutrition with an expected length of stay of ≥ 7 days. Eligible inpatients will be randomized into a 1:1 ratio, with one receiving a multidisciplinary team intervention and the other receiving standard medical treatment or care alone. A structured comprehensive assessment of anthropometry, nutritional status, cognition, mood, functional performance, and quality of life will be conducted twice. These assessments will take place on the day of group allocation and 1 year after discharge, and a structured screening assessment for elderly malnutrition will be conducted at 3 and 6 months after discharge using the MNA-SF. The primary outcome will be nutritional status based on changes in MNA-SF scores at 3, 6 months, and 1 year. The secondary outcome will be changes in cognition, mood, functional status, length of hospital stay, and all-cause mortality 1 year after discharge.

Discussion

Guided by the concept of interdisciplinary cooperation, this study will establish a multidisciplinary nutrition support team that will develop an innovative intervention strategy that integrates nutritional screenings, evaluations, education, consultation, support, and monitoring. Moreover, nutritional intervention and dietary fortification will be provided to hospitalized elderly patients with or at risk of malnutrition. The nutrition support team will formulate a clinical map for malnutrition in elderly patients with standardized diagnosis and treatment for malnutrition in this population.

Factors Related to Oral Intake of Food by Hospitalized Patients with Malnutrition under the Care of a Nutrition Support Team

This study aimed to evaluate the role of the general condition and oral health status in determining the primary nutritional route and suitable food form for oral ingestion among malnourished inpatients. This cross-sectional study included 255 inpatients referred to a nutrition support team (NST), which included dental professionals, at an acute care hospital. We assessed the participants’ basic information, and Dysphagia Severity Scale (DSS) and Oral Health Assessment Tool (OHAT) scores. The nutritional intake mode was evaluated based on the Functional Oral Intake Scale scores at the initial NST consultation (FOIS-I), and then revised by the NST based on the participants’ general condition and oral health (FOIS-R). There was a divergence between FOIS-I and FOIS-R, with FOIS-R being significantly higher than FOIS-I (p < 0.001). Logistic regression analysis of FOIS-R identified that consciousness level (odds ratio (OR): 0.448; 95% confidence interval (CI): 0.214–0.935) and DSS (OR: 3.521; 95% CI: 2.574–4.815) significantly affected the oral nutrition intake. Among participants who could ingest orally (FOIS-R ≥ 3; n = 126), FOIS score had significant negative and positive associations with the OHAT and DSS scores, respectively. These findings suggest that appropriate assessment of oral health status, including swallowing function, might contribute to high-quality nutrition management.

Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition: Revised 2021 Standards of Practice and Standards of Professional Performance for Registered Dietitian Nutritionists (Competent, Proficient, and Expert) in Nutrition Support

Nutrition support is a therapy that crosses all ages, diseases, and conditions as health care practitioners strive to meet the nutritional requirements of individuals who are unable to meet nutritional and/or hydration needs with oral intake alone. Registered dietitian nutritionists (RDNs), as integral members of the nutrition support team provide needed information, such as identification of malnutrition risk, macro- and micronutrient requirements, and type of nutrition support therapy (eg, enteral or parenteral), including the route (eg, nasogastric vs nasojejunal or tunneled catheter vs port). The Dietitians in Nutrition Support Dietetic Practice Group, American Society for Parenteral and Enteral Nutrition, along with the Academy of Nutrition and Dietetics Quality Management Committee, have updated the Standards of Practice (SOP) and Standards of Professional Performance (SOPP) for RDNs working in nutrition support. The SOP and SOPP for RDNs in Nutrition Support provide indicators that describe the following 3 levels of practice: competent, proficient, and expert. The SOP uses the Nutrition Care Process and clinical workflow elements for delivering patient/client care. The SOPP describes the 6 domains that focus on professional performance. Specific indicators outlined in the SOP and SOPP depict how these standards apply to practice. The SOP and SOPP are complementary resources for RDNs and are intended to be used as a self-evaluation tool for assuring competent practice in nutrition support and for determining potential education and training needs for advancement to a higher practice level in a variety of settings.

Systematic review with meta-analysis: effects of implementing a nutrition support team for in-hospital parenteral nutrition

BACKGROUND

Nutrition support teams (NST) may improve parenteral nutrition (PN) outcomes. No previous systematic review has provided conclusive data on catheter-related infection (CRI) occurrence after NST introduction, nor have previous studies performed meta-analysis or graded the evidence.

AIMS

To systematically evaluate the effects of implementing an NST for hospitalised adults on PN and compare these with standard care.

METHODS

This was a systematic review and meta-analysis, pre-registered in PROSPERO (CRD42020218094). On November 24, 2020, PubMed, Web of science, Scopus, Embase, Cochrane Library, and Clinical Key were searched. Clinical trials and observational studies with a standard care comparator were included. Primary outcome was relative reduction in CRI rate. A random-effects meta-analysis was used to estimate effects, and evidence was rated using Cochrane and GRADE methodologies.

RESULTS

Twenty-seven studies with 8166 patients were included. Across 10 studies, NST introduction reduced the CRI rate (IRR = 0.32, 95% CI: 0.19-0.53) with -8 (95% CI: -12 to -5) episodes per 1000 catheter days compared with standard care. Hypophosphataemia occurred less frequently (IRD = -12%, 95% CI: -24% to -1%) and 30-day mortality decreased (IRD = -6%, 95% CI: -11% to -1%). Inappropriate PN use decreased, both judged by indication (IRD = -18%, 95% CI: -28% to -9%) and duration (IRD = -21%, 95% CI: -33% to -9%). Evidence was rated very low to moderate.

CONCLUSIONS

This study documents the clinical impact of introducing an NST, with moderate-grade evidence for the reduction of CRI occurrence compared with standard care. Further, NST introduction significantly reduced metabolic complications, mortality, and inappropriate PN use.

An overview of the current management of short-bowel syndrome in pediatric patients

Short-bowel syndrome (SBS) is defined as a state of malabsorption after resection or loss of a major portion of the bowel due to congenital or acquired factors. This article presents an overview on the recent management of pediatric SBS. The pediatric SBS population is very heterogeneous. The incidence of SBS is estimated to be 24.5 per 100,000 live births. The nutritional, medical, and surgical therapies available require a comprehensive evaluation. Thus, multidisciplinary intestinal rehabilitation programs (IRPs) are necessary for the management of these complex patients. The key points of focus in IRP management are hepato-protective strategies to minimize intestinal failure-associated liver disease; the aggressive prevention of catheter-related bloodstream infections; strategic nutritional supply to optimize the absorption of enteral calories; and the management and prevention of small bowel bacterial overgrowth, nephrocalcinosis, and metabolic bone disease. As the survival rate of children with SBS currently exceeds 90%, the application of small bowel transplantation has been evolving. The introduction of innovative treatments, such as combined therapy of intestinotrophic hormones, including glucagon-like peptide-2, may lead to further improvements in patients' quality of life.

Risks in Management of Enteral Nutrition in Intensive Care Units: A Literature Review and Narrative Synthesis

Critically ill patients in the intensive care unit (ICU) have a high risk of developing malnutrition, and this is associated with poorer clinical outcomes. In clinical practice, nutrition, including enteral nutrition (EN), is often not prioritized. Resulting from this, risks and safety issues for patients and healthcare professionals can emerge. The aim of this literature review, inspired by the Rapid Review Guidebook by Dobbins, 2017, was to identify risks and safety issues for patient safety in the management of EN in critically ill patients in the ICU. Three databases were used to identify studies between 2009 and 2020. We assessed 3495 studies for eligibility and included 62 in our narrative synthesis. Several risks and problems were identified: No use of clinical assessment or screening nutrition assessment, inadequate tube management, missing energy target, missing a nutritionist, bad hygiene and handling, wrong time management and speed, nutritional interruptions, wrong body position, gastrointestinal complication and infections, missing or not using guidelines, understaffing, and lack of education. Raising awareness of these risks is a central aspect in patient safety in ICU. Clinical experts can use a checklist with 12 identified top risks and the recommendations drawn up to carry out their own risk analysis in clinical practice.

Nutritional Care of Patients Admitted to Hospital for Alcohol Withdrawal: A 5-Year Retrospective Audit

AIM

The aim of this study was to describe the characteristics and the nutritional approaches implemented with patients undergoing alcohol withdrawal.

METHODS

A retrospective analysis of medical records for patients admitted to a tertiary hospital for alcohol withdrawal was completed over a 5-year period 2013-2017. Data on nutrition-related assessment and management were extracted and descriptively analysed.

RESULTS

A total of 109 medical records were included (M = 73, F = 36), with the mean age of patients 47.3 years (SD ± 11.2, range 22-70). The average length of stay was 3.7 days (SD ± 3.9, range 0.70-27.8). Approaches towards nutritional care emerged from micronutrient assessment and supplementation and/or dietetic consultation. Nutrition-related biochemistry data was available for most patients, notably serum levels of sodium, urea and creatinine (102 patients; 93.5%) and magnesium and phosphate (66 patients, 60.5%). There was evidence of some electrolyte abnormalities on admission to hospital. Eight patients had serum micronutrient status assessed; no patients had serum thiamine levels assessed. Parenteral thiamine was provided to 96 patients (88.0%) for 1.9 days (SD ± 1.1, range 1.0-6.0) with a mean dose of 2458.7 mg (SD ± 1347.6, range 300-6700 mg). Multivitamin supplementation was provided to 24 patients (22.0%). Only 23 patients (21.2%) were seen by a dietician of whom 16 underwent a comprehensive nutritional assessment and 3 were screened using the malnutrition screening tool.

CONCLUSION

Inconsistent nutritional assessment and management practices were identified across a diverse population group, whilst nutritional professionals were underutilized. Future research should benchmark current guidelines and multidisciplinary approaches considering the role of nutritional specialists in the team.
