Malnutrition prevalence in The Netherlands: results of the Annual Dutch National Prevalence Measurement of Care Problems

Applying generative AI with retrieval augmented generation to summarize and extract key clinical information from electronic health records

BACKGROUND

Malnutrition is a prevalent issue in aged care facilities (RACFs), leading to adverse health outcomes. The ability to efficiently extract key clinical information from a large volume of data in electronic health records (EHR) can improve understanding about the extent of the problem and developing effective interventions. This research aimed to test the efficacy of zero-shot prompt engineering applied to generative artificial intelligence (AI) models on their own and in combination with retrieval augmented generation (RAG), for the automating tasks of summarizing both structured and unstructured data in EHR and extracting important malnutrition information.

METHODOLOGY

We utilized Llama 2 13B model with zero-shot prompting. The dataset comprises unstructured and structured EHRs related to malnutrition management in 40 Australian RACFs. We employed zero-shot learning to the model alone first, then combined it with RAG to accomplish two tasks: generate structured summaries about the nutritional status of a client and extract key information about malnutrition risk factors. We utilized 25 notes in the first task and 1,399 in the second task. We evaluated the model's output of each task manually against a gold standard dataset.

RESULT

The evaluation outcomes indicated that zero-shot learning applied to generative AI model is highly effective in summarizing and extracting information about nutritional status of RACFs' clients. The generated summaries provided concise and accurate representation of the original data with an overall accuracy of 93.25%. The addition of RAG improved the summarization process, leading to a 6% increase and achieving an accuracy of 99.25%. The model also proved its capability in extracting risk factors with an accuracy of 90%. However, adding RAG did not further improve accuracy in this task. Overall, the model has shown a robust performance when information was explicitly stated in the notes; however, it could encounter hallucination limitations, particularly when details were not explicitly provided.

CONCLUSION

This study demonstrates the high performance and limitations of applying zero-shot learning to generative AI models to automatic generation of structured summarization of EHRs data and extracting key clinical information. The inclusion of the RAG approach improved the model performance and mitigated the hallucination problem.

The perceptions of food service staff in a nursing home on an upcoming transition towards a healthy and sustainable food environment: a qualitative study

BACKGROUND

Healthy and sustainable food environments are urgently needed, also in nursing and residential care homes. Malnutrition in care homes is becoming an increasing problem as populations worldwide are ageing and many older people do not consume sufficient protein, fibre, fruit, and vegetables. Nursing homes also often experience a lot of food waste. A transition in the food environment like a nursing home, involves the participation of facility management and food service staff members. This study aims to map out their perceived barriers and facilitators for this transition.

METHODS

A qualitative study using semi-structured interviews was conducted with food service staff members (n = 16), comprising of kitchen staff (n = 4), wait staff (n = 10), and facility management (n = 2) of two nursing homes in the Netherlands. Thematic analysis was used to derive content and meaning from transcribed interviews.

RESULTS

Four main themes were identified. Theme 1: 'Communication, transparency and accountability in the chain', highlighting the lack of effective communication flows and a fragmented overview of the food service chain as a whole. Theme 2: 'Understanding, knowledge and ability of the concepts healthy and sustainable', revealing the gap in staff's understanding of these abstract concepts, despite perceiving themselves as having sufficient knowledge and ability. Theme 3: 'The pampering service mind-set', highlighting the contradiction in the staff's shared goal of proving the highest quality of life for residents while also pampering them in ways that may not align with promoting healthy and sustainable food choices. Theme 4: 'Transition is important but hard to realize', describing the barriers such as existing routines and a lack of resources as challenges to implementing changes in the food service.

CONCLUSIONS

Facilitators to transitioning nursing homes towards a healthy and sustainable food environment as perceived by staff members included transparent communication, accountability in the food supply chain, staff's perceived ability and shared goal, while barriers included lack of understanding of the concepts healthy and sustainable, the current pampering mindset, and top-down decision-making. These findings provide valuable insights for nursing homes seeking to transition towards a healthier and more sustainable food environment.

A multi-center prospective study of plant-based nutritional support in adult community-based patients at risk of disease-related malnutrition

Introduction

There is an emerging need for plant-based, vegan options for patients requiring nutritional support.

Methods

Twenty-four adults at risk of malnutrition (age: 59 years (SD 18); Sex: 18 female, 6 male; BMI: 19.0 kg/m2 (SD 3.3); multiple diagnoses) requiring plant-based nutritional support participated in a multi-center, prospective study of a (vegan suitable) multi-nutrient, ready-to-drink, oral nutritional supplement (ONS) [1.5 kcal/mL; 300 kcal, 12 g protein/200 mL bottle, mean prescription 275 mL/day (SD 115)] alongside dietary advice for 28 days. Compliance, anthropometry, malnutrition risk, dietary intake, appetite, acceptability, gastrointestinal (GI) tolerance, nutritional goal(s), and safety were assessed.

Results

Patients required a plant-based ONS due to personal preference/variety (33%), religious/cultural reasons (28%), veganism/reduce animal-derived consumption (17%), environmental/sustainability reasons (17%), and health reasons (5%). Compliance was 94% (SD 16). High risk of malnutrition ('MUST' score ≥ 2) reduced from 20 to 16 patients (p = 0.046). Body weight (+0.6 kg (SD 1.2), p = 0.02), BMI (+0.2 kg/m2 (SD 0.5), p = 0.03), total mean energy (+387 kcal/day (SD 416), p < 0.0001) and protein intake (+14 g/day (SD 39), p = 0.03), and the number of micronutrients meeting the UK reference nutrient intake (RNI) (7 vs. 14, p = 0.008) significantly increased. Appetite (Simplified Nutritional Appetite Questionnaire (SNAQ) score; p = 0.13) was maintained. Most GI symptoms were stable throughout the study (p > 0.06) with no serious adverse events related.

Discussion

This study highlights that plant-based nutrition support using a vegan-suitable plant-based ONS is highly complied with, improving the nutritional outcomes of patients at risk of malnutrition.

Are We Ready for a New Approach to Comparing Coverage and Reimbursement Policies for Medical Nutrition in Key Markets: An ISPOR Special Interest Group Report

OBJECTIVES

Healthcare policy makers should ensure optimal patient access to medical nutrition (MN) as part of the management of nutrition-related disorders and conditions. Questions remain whether current healthcare policies reflect the clinical and economic benefits of MN. The objective of this article is to characterize coverage and reimbursement of MN, defined as food for special medical purposes/medical food for a diverse set of countries, including Australia, Belgium, Brazil, Canada, China, France, Germany, Hong Kong, Italy, Japan, The Netherlands, Singapore, Spain, United Kingdom, and United States.

METHODS

Data sources included published literature and online sources. ISPOR's Nutrition Economics Special Interest Group developed a data collection form to guide data extraction that included reimbursement coverage, years that reimbursement policies were established, and presence of a formal health technology assessment (HTA) for MN technologies.

RESULTS

Reimbursement coverage of MN technologies varied across the countries that were reviewed. All but 3 countries limited coverage to specific formulations of products, regardless of demonstrated clinical benefit. The year that reimbursement policies were established varied across countries (ranging from 1984 to 2017), and only 4 countries regularly update policies. France and Brazil are the only countries with a formal HTA process for MN technologies.

CONCLUSIONS

Most countries have limited MN reimbursement, have not updated reimbursement policies, and lack HTA for MN technologies. These limitations may lead to suboptimal access to MN technologies where they are indicated to manage nutrition-related disorders and conditions, with the potential of negatively affecting patient and healthcare system outcomes.

Which factors influence the prevalence of institution-acquired falls? Results from an international, multi-center, cross-sectional survey

PURPOSE

Falls are a highly prevalent problem in hospitals and nursing homes with serious negative consequences such as injuries, increased care dependency, or even death. The aim of this study was to provide a comprehensive insight into institution-acquired fall (IAF) prevalence and risk factors for IAF in a large sample of hospital patients and nursing home residents among five different countries.

DESIGN

This study reports the outcome of a secondary data analysis of cross-sectional data collected in Austria, Switzerland, the Netherlands, Turkey, and the United Kingdom in 2017 and 2018. These data include 58,319 datapoints from hospital patients and nursing home residents.

METHODS

Descriptive statistics, statistical tests, logistic regression, and generalized estimating equation (GEE) models were used to analyze the data.

FINDINGS

IAF prevalence in hospitals and nursing homes differed significantly between the countries. Turkey (7.7%) had the highest IAF prevalence rate for hospitals, and Switzerland (15.8%) had the highest IAF prevalence rate for nursing homes. In hospitals, our model revealed that IAF prevalence was associated with country, age, care dependency, number of medical diagnoses, surgery in the last two weeks, and fall history factors. In nursing homes, care dependency, diseases of the nervous system, and fall history were identified as significant risk factors for IAF prevalence.

CONCLUSIONS

This large-scale study reveals that the most important IAF risk factor is an existing history of falls, independent of the setting. Whether a previous fall has occurred within the last 12 months is a simple question that should be included on every (nursing) assessment at the time of patient or resident admission. Our results guide the development of tailored prevention programs for persons at risk of falling in hospitals and nursing homes.

Eat what you want and when you want. Effect of a free choice menu on the energy and protein intake of geriatric medical patients

BACKGROUND

Geriatric medical patients are often at nutritional risk when admitted to hospital. More flexible meal service concepts may prove successful in improving nutritional intake.

AIM

To evaluate whether the Free Choice Menu (FCM), a new room service resembling meal service concept, improves energy and protein intake in a population of geriatric medical patients compared with the traditional concept of serving meals from a trolley with a fixed menu (trolley).

METHODS

Data were collected consecutive in a geriatric ward at Slagelse Hospital (Denmark) before (autumn 2018; n = 98) and after (autumn 2020; n = 52) implementing the Free Choice Menu. Weighed dietary intake was recorded for three full days for each patient.

RESULTS

Energy and protein intake did not differ significantly when comparing the two meal service concepts (trolley: 6124 kJ; 52.6 g and FCM: 5923 kJ; 47.1 g) over three days. The FCM concept showed however a significantly higher energy and protein intake for the dinner (relative to the other meals), whereas a higher percentage of protein and energy intake was covered by oral nutritional supplements in the trolley concept. The majority of the participants met the recommendations for energy intake, while only a minority met the recommendations for protein intake. Plate waste was significantly lower (p = 0.0005) at the lunch meal for the FCM concept (15.6%) compared with the trolley concept (26.1%).

CONCLUSION

When implementing a FCM, energy and protein intake was maintained and patients received more energy and protein from the dinner and less from oral nutritional supplements. However, the introduction of a free choice of meals concept did not in itself ensure nutritional intake in geriatric medical patients.

Nutrition and cutaneous wound healing

Wound healing is a complex and energy-demanding process. The relationship between nutrition and wound healing has been recognized for many centuries. Several studies have indicated that nutritional deficiencies are more prevalent among patients with chronic wounds. Malnutrition may alter the inflammatory response, collagen synthesis, and wound tensile strength, all of which are crucial for wound healing. Although the specific role of nutrition and supplementation in wound care remains uncertain, it is necessary to identify and correct nutritional imbalances to avoid any potential deterioration of the healing process. It is also important to recognize the differences in pathophysiology between acute and chronic wounds. A burn, surgical, or a traumatic wound is different from a diabetic foot ulcer, which is different from a pressure ulcer. Chronic wounds are more prevalent in the aging population, and patients often have underlying comorbidities, such as diabetes mellitus, peripheral vascular disease, connective tissue disease, or other systemic illnesses that may alter energy metabolism and contribute to impaired healing. Management approaches to acute wound care may not apply universally to chronic wounds. In this review, we discuss the available data and possible roles for nutrition in wound healing.

Association between malnutrition risk and pain in older hospital patients

OBJECTIVE

To describe the prevalence of malnutrition risk and pain in older hospital patients and characterise the association between these two problems.

RESEARCH METHODS AND PROCEDURES

The study includes a secondary data analysis of data collected in two cross-sectional studies. Data collection was performed in 2017 and 2018 using a standardised and tested questionnaire. The study protocol was approved by an ethical committee.

RESULTS

Data from 3406 patients were analysed. Among the participants, 24.6% of the patients were at risk of malnutrition, and 59.6% of the patients reported feeling pain. A significantly higher number of patients with pain (26.4%) were at risk of malnutrition than patients without pain (22.1%). The multivariate logistic regression analysis showed that patients with severe/very severe or unbearable pain were 1.439 times more likely to develop a risk of malnutrition than patients without pain. Patients with cancer or diseases of the digestive system were twice as likely to develop malnutrition than those without these diseases.

CONCLUSIONS

The results of this study show that older patients with severe pain are at higher risk of developing a risk of malnutrition than those without pain, although the study design (cross-sectional) does not imply causality. Therefore, special efforts should be made to assess pain in these patients to reduce the negative consequences of this pain, such as malnutrition.

Cultural and Ethical Barriers to Cancer Treatment in Nursing Homes and Educational Strategies: A Scoping Review

(1) Background: The aging of the population, the increase in the incidence of cancer with age, and effective chronic oncological treatments all lead to an increased prevalence of cancer in nursing homes. The aim of the present study was to map the cultural and ethical barriers associated with the treatment of cancer and educational strategies in this setting. (2) Methods: A systematic scoping review was conducted until April 2021 in MEDLINE, Embase, and CINAHL. All articles assessing continuum of care, paramedical education, and continuing education in the context of older cancer patients in nursing homes were reviewed. (3) Results: A total of 666 articles were analyzed, of which 65 studies were included. Many factors interfering with the decision to investigate and treat, leading to late- or unstaged disease, palliative-oriented care instead of curative, and a higher risk of unjustified transfers to acute care settings, were identified. The educational strategies explored in this context were generally based on training programs. (4) Conclusions: These results will allow the co-construction of educational tools intended to develop knowledge and skills to improve diagnostic and therapeutic decision-making, the consistency of care, and, ultimately, the quality of life of older cancer patients in nursing homes.

Improving the quality of nursing care in Austria: 10 years of success

AIMS

We provide more updated and comprehensive insights, including descriptions of changes that have taken place in the quality of pressure injury care provided in hospitals over a 10-year period.

BACKGROUND

Various nursing quality measurements do not present a comprehensive view on nursing-sensitive quality indicators or place a focus on one specific care problem.

METHODS

It is a repeated cross-sectional multicentre study conducted annually on 1 day including comprehensive data regarding nursing-sensitive care problems and quality indicators on the structure, process and outcome levels.

RESULTS

The prevalence of pressure injuries decreased over the years from 4.4% to 2.9%, and the frequency of interventions increased.

CONCLUSION

The Nursing Quality Measurement 2.0 initiative shows considerable improvements over a 10-year period. Therefore, the maintenance of such nursing databases should be treated as a prerequisite to providing high-quality nursing care and safe nursing practice. One main benefit of creating and maintaining such databases is that allow users to screen for improvements, for example in pressure injury care. These observations can be used to develop marketing strategies and/or to empower and engage nursing staff.

IMPLICATIONS FOR NURSING MANAGEMENT

Participation in such quality measurements allows the comparison of data collected in wards and institutions in many different countries, enabling them to set appropriate benchmarks. Furthermore, the results can be compared over a period of time, highlighting systematic changes, trends or improvements (e.g., due to implemented innovations).

Effectiveness of individualised nutritional care plans to reduce malnutrition during hospitalisation and up to 3 months post-discharge: a systematic scoping review

OBJECTIVES

The prevalence of malnutrition after hospitalisation is reported to be 20%-45%, which may lead to adverse outcomes, as malnutrition increases the risk of complications, morbidity, mortality and loss of function. Improving the quality of nutritional treatment in hospitals and post-discharge is necessary, as hospital stays tend to be short. We aimed to identify and map studies that assess the effectiveness of individualised nutritional care plans to reduce malnutrition during hospitalisation and for the first 3 months post-discharge.

DESIGN

This was a systematic scoping review.

METHODS

We systematically searched for all types of studies in the following databases: EMBASE, MEDLINE via PubMed, and the Cumulative Index to Nursing and Allied Health Literature, with no restriction on data or publication language. We also reviewed the reference lists of the included studies. The abstracts and full articles were simultaneously screened by two independent reviewers. Differences of opinion were discussed among the two investigators, and a third reviewer assisted with the discussion until consensus was reached. Studies in which the patients received an individual nutritional care plan related to their hospital stay and were followed up post-discharge were included. We then conducted a thematic content analysis of the extracted literature.

RESULTS

Nine randomised controlled trial studies met the inclusion criteria: six were conducted in Scandinavian countries. All studies were mainly conducted among elderly patients (mean ages varied from 75 to 88 years). The review studies measured 10 different outcomes; the most common outcomes were nutritional status and readmission. Six studies reported one or more significant positive intervention effect. Inconsistent results were identified for four outcome variables.

CONCLUSIONS

Individualised nutritional care plans and follow-up home visits might improve patients' nutritional status. However, there is need for a systematic review that assesses study quality and extends the time to 6 months post-discharge.

Nutritional status and structural brain changes in Alzheimer's disease: The NUDAD project

INTRODUCTION

Weight loss is associated with higher mortality and progression of cognitive decline, but its associations with magnetic resonance imaging (MRI) changes related to Alzheimer's disease (AD) are unknown.

METHODS

We included 412 patients from the NUDAD project, comprising 129 with AD dementia, 107 with mild cognitive impairment (MCI), and 176 controls. Associations between nutritional status and MRI measures were analyzed using linear regression, adjusted for age, sex, education, cognitive functioning, and cardiovascular risk factors.

RESULTS

Lower body mass index (BMI), fat mass (FM), and fat free mass index were associated with higher medial temporal atrophy (MTA) scores. Lower BMI, FM, and waist circumference were associated with more microbleeds. Stratification by diagnosis showed that the observed associations with microbleeds were only significant in MCI.

DISCUSSION

Lower indicators of nutritional status were associated with more MTA and microbleeds, with largest effect sizes in MCI.

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.

Effects of High-Tech Urban Agriculture on Cooking and Eating in Dutch Nursing Homes

Questions have arisen about the sustainability of the industrialised food system. Alternatives like urban agriculture have emerged to reduce the negative social, environmental and health impacts of industrial agriculture. Such new food supply chains can change the way that people acquire and process food. This study looks at high-tech indoor gardening practices in nursing homes for elderly people, studying four nursing homes in the Dutch city of Velp. We used both qualitative and quantitative approaches to collect data, using site visits, a survey amongst employees, and semi-structured interviewees with residents and decision makers. Inspired by social practice theory, we aimed to understand the transformation of existing practices, investigating how the gardens affect cooking and eating practices, and how their constitutive elements of meaning, material and competences enable these transformations. Our work shows that the indoor gardens resulted in an integration of gardening and the resulting harvest into cooking practices, which in turn transformed residents’ eating practices. Appreciation of the taste of fresh vegetables and appearance of the meal decorated by fresh vegetables, as well as observing the growth of plants and their use, holds value for the elderly residents. Employees welcome the possibility to serve healthier meals. The integration of indoor gardens in existing cooking practices is more successful when employees have gardening and/or cooking competences, when they enjoy cooking and when they do not already cook with fresh ingredients. The gardens are more easily integrated when they are easily accessible. The materiality of the gardens does not require fully equipped kitchens.

Health and Sustainability in Public Meals-An Explorative Review

The world is facing a number of challenges related to food consumption. These are, on the one hand, health effects and, on the other hand, the environmental impact of food production. Radical changes are needed to achieve a sustainable and healthy food production and consumption. Public and institutional meals play a vital role in promoting health and sustainability, since they are responsible for a significant part of food consumption, as well as their “normative influence” on peoples’ food habits. The aim of this paper is to provide an explorative review of the scientific literature, focusing on European research including both concepts of health and sustainability in studies of public meals. Of >3000 papers, 20 were found to satisfy these criteria and were thus included in the review. The results showed that schools and hospitals are the most dominant arenas where both health and sustainability have been addressed. Three different approaches in combining health and sustainability have been found, these are: “Health as embracing sustainability”, “Sustainability as embracing health” and “Health and sustainability as separate concepts”. However, a clear motivation for addressing both health and sustainability is most often missing.

Malnutrition and related risk factors in older adults from different health-care settings: an enable study

Objective:

The origin of malnutrition in older age is multifactorial and risk factors may vary according to health and living situation. The present study aimed to identify setting-specific risk profiles of malnutrition in older adults and to investigate the association of the number of individual risk factors with malnutrition.

Design:

Data of four cross-sectional studies were harmonized and uniformly analysed. Malnutrition was defined as BMI < 20 kg/m² and/or weight loss of >3 kg in the previous 3–6 months. Associations between factors of six domains (demographics, health, mental function, physical function, dietary intake-related problems, dietary behaviour), the number of individual risk factors and malnutrition were analysed using logistic regression.

Setting:

Community (CD), geriatric day hospital (GDH), home care (HC), nursing home (NH).

Participants:

CD older adults (n 1073), GDH patients (n 180), HC receivers (n 335) and NH residents (n 197), all ≥65 years.

Results:

Malnutrition prevalence was lower in CD (11 %) than in the other settings (16–19 %). In the CD sample, poor appetite, difficulties with eating, respiratory and gastrointestinal diseases were associated with malnutrition; in GDH patients, poor appetite and respiratory diseases; in HC receivers, younger age, poor appetite and nausea; and in NH residents, older age and mobility limitations. In all settings the likelihood of malnutrition increased with the number of potential individual risk factors.

Conclusions:

The study indicates a varying relevance of certain risk factors of malnutrition in different settings. However, the relationship of the number of individual risk factors with malnutrition in all settings implies comprehensive approaches to identify persons at risk of malnutrition early.

Modifiable patient-related factors associated with pressure ulcers on the sacrum and heels: Secondary data analyses

AIM

To explore factors associated with the presence of category I-IV pressure ulcers on the sacrum and heels.

DESIGN

Cross-sectional, secondary data analysis using data collected from the Landelijke Prevalentiemeting Zorgproblemen (LPZ) project, a multicentre prevalence study including nursing home residents and community care clients (N = 4,842) in the Netherlands in 2017.

METHODS

A single binary logistic regression model was designed to identify factors associated with the presence of pressure ulcers. Additionally, a multiple binary logistic regression model including modifiable explanatory factors associated with the presence of pressure ulcers was designed.

RESULTS

Impaired mobility, friction and shear (evaluated using the Braden Scale) are significantly associated with the presence of both sacral and heel category I-IV pressure ulcers. Incontinence-associated dermatitis is significantly associated with category I-IV sacral pressure ulcers.

CONCLUSION

In pressure ulcer prevention, nursing interventions should focus on frequent repositioning and mobilization while avoiding exposure of the skin to friction and shear. The need to consider incontinence-associated dermatitis, incontinence and moisture as important factors in pressure ulcer risk assessment is confirmed.

IMPACT

Pressure ulcers occur when skin and tissues are deformed between bony prominences and the support surface in a sitting or lying position. They are the result of a complex interaction between direct causal factors and a wide range of indirect factors. Recognition of these factors influences risk assessment guidance and practice. Knowledge of skin-specific factors at the patient level, modifiable by nursing interventions, enables a better targeted and tailored preventive approach.

Medical Nutrition Terminology and Regulations in the United States and Europe-A Scoping Review: Report of the ISPOR Nutrition Economics Special Interest Group

BACKGROUND

The term medical nutrition (MN) refers to nutritional products used under medical supervision to manage disease- or condition-related dietary needs. Standardized MN definitions, aligned with regulatory definitions, are needed to facilitate outcomes research and economic evaluation of interventions with MN.

OBJECTIVES

Ascertain how MN terms are defined, relevant regulations are applied, and to what extent MN is valued.

METHODS

ISPOR's Nutrition Economics Special Interest Group conducted a scoping review of scientific literature on European and US MN terminology and regulations, published between January 2000 and August 2015, and pertinent professional and regulatory Web sites. Data were extracted, reviewed, and reconciled using two-person teams in a two-step process. The literature search was updated before manuscript completion.

RESULTS

Of the initial 1687 literature abstracts and 222 Web sites identified, 459 records were included in the analysis, of which 308 used MN terms and 100 provided definitions. More than 13 primary disease groups as per International Classification of Disease, Revision 10 categories were included. The most frequently mentioned and defined terms were enteral nutrition and malnutrition. Less than 5% of the records referenced any MN regulation. The health economic impact of MN was rarely and insufficiently (n = 19 [4.1%]) assessed, although an increase in economic analyses was observed.

CONCLUSIONS

MN terminology is not consistently defined, relevant European and US regulations are rarely cited, and economic evaluations are infrequently conducted. We recommend adopting consensus MN terms and definitions, for example, the European Society for Clinical Nutrition and Metabolism consensus guideline 2017, as a foundation for developing reliable and standardized medical nutrition economic methodologies.

Large regional disparities in prevalence, management and reimbursement of hospital undernutrition

BACKGROUND/OBJECTIVES

Undernutrition is a frequent condition among hospitalized patients, with a significant impact on patient's outcome and hospital costs. Whether undernutrition is reported similarly at the national level has seldom been assessed. We aimed to (1) assess regional differences within Switzerland regarding undernutrition prevalence, management, and cost reimbursement and (2) identify the factors associated with reporting of undernutrition status and its management.

SUBJECTS/METHODS

Observational cross-sectional study including routine statistics from the Swiss hospital discharge databases for years 2013 and 2014 (seven administrative regions). All adults aged ≥20 with length of hospital stay of at least 1 day was included. Reported undernutrition was defined based on the International Classification of Diseases (ICD)-10 codes. Nutritional management and "reimbursable" undernutrition codes were also assessed.

RESULTS

Of the initial 1,784,855 hospitalizations, 3.6% had reported undernutrition, the prevalence ranging between 1.8% (Ticino) and 4.6% (Mittelland). Use of different undernutrition-related ICD-10 codes also varied considerably across regions. Multivariable analysis showed a twofold variation in reported undernutrition: multivariable-adjusted odds ratio and 95% confidence interval relative to Eastern Switzerland: 2.31 (2.23, 2.38) for Mittelland and 0.74 (0.70, 0.79) for Ticino. Over half (59.6%) of hospitalizations with reported undernutrition also included information on undernutrition management, ranging between 28.6% (Ticino) and 67.2% (Zürich). Only one third (36.8%) of undernutrition-related codes were reimbursable, ranging between 8.3% (Ticino) and 50.7% (Zürich).

CONCLUSIONS

In Switzerland, there is considerable regional variation regarding reporting of undernutrition prevalence, management, and cost reimbursement. Undernutrition appears to be insufficiently managed and valued.

Prevalence of Malnutrition in Hospitalized Patients: a Multicenter Cross-sectional Study

BACKGROUND

Malnutrition is associated with many adverse clinical outcomes. The present study aimed to identify the prevalence of malnutrition in hospitalized patients in Korea, evaluate the association between malnutrition and clinical outcomes, and ascertain the risk factors of malnutrition.

METHODS

A multicenter cross-sectional study was performed with 300 patients recruited from among the patients admitted in 25 hospitals on January 6, 2014. Nutritional status was assessed by using the Subjective Global Assessment (SGA). Demographic characteristics and underlying diseases were compared according to nutritional status. Logistic regression analysis was performed to identify the risk factors of malnutrition. Clinical outcomes such as rate of admission in intensive care units, length of hospital stay, and survival rate were evaluated.

RESULTS

The prevalence of malnutrition in the hospitalized patients was 22.0%. Old age (≥ 70 years), admission for medical treatment or diagnostic work-up, and underlying pulmonary or oncological disease were associated with malnutrition. Old age and admission for medical treatment or diagnostic work-up were identified to be risk factors of malnutrition in the multivariate analysis. Patients with malnutrition had longer hospital stay (SGA A = 7.63 ± 6.03 days, B = 9.02 ± 9.96 days, and C = 12.18 ± 7.24 days, P = 0.018) and lower 90-day survival rate (SGA A = 97.9%, B = 90.7%, and C = 58.3%, P < 0.001).

CONCLUSION

Malnutrition was common in hospitalized patients, and resulted in longer hospitalization and associated lower survival rate. The rate of malnutrition tended to be higher when the patient was older than 70 years old or hospitalized for medical treatment or diagnostic work-up compared to elective surgery.

Malnutrition upon Hospital Admission in Geriatric Patients: Why Assess It?

Objective

To assess the prevalence of malnutrition according to the new ESPEN definition in a population of geriatric hospital patients and to determine how malnutrition affects the length of hospital stay (LOS) and hospital mortality.

Design

A retrospective analysis of data gathered during nutritional screening surveys carried out three consecutive years, from 2012 to 2014, in an Italian geriatric research hospital (INRCA, Ancona) was performed. On the day of the study, demographic data, data on clinical conditions and the nutritional status of newly admitted patients were collected. Patients were screened for malnutrition risk using the Malnutrition Universal Screening Tool (MUST). Subsequently, malnutrition was diagnosed, for subjects at high risk, following the criteria suggested by the European Association for Clinical Nutrition and Metabolism [body mass index (BMI) < 18.5 kg/m² or different combinations of unintentional weight loss over time and BMI values]. Sensitivity, specificity, positive and negative predictive value of MUST compared to ESPEN criteria were assessed. The characteristics of patients with a diagnosis of malnutrition were compared to those of non-malnourished patients. The impact of malnutrition on LOS and hospital mortality was investigated through logistic and linear regression models.

Setting

The study was performed in an Italian geriatric research hospital (INRCA, Ancona).

Subjects

Two hundred eighty-four newly hospitalized geriatric patients from acute care wards (mean age 82.8 ± 8.7 years), who gave their written consent to participate in the study, were enrolled.

Results

According to the MUST, high risk of malnutrition at hospitalization was found in 28.2% of patients. Malnutrition was diagnosed in 24.6% of subjects. The malnutrition was an independent predictor of both the LOS and hospital mortality. The multivariate analyses—linear and logistic regression—were performed considering different potential confounders contemporarily. The results showed that the malnutrition is an independent predictor of LOS and hospital mortality. Malnourished subjects were hospitalized almost 3 days longer compared to non-malnourished patients (p = 0.047; CI 0.04–5.80). The risk of death during hospitalization was 55% higher for malnourished patients (p = 0.037; CI 0.21–0.95).

Conclusion

A new ESPEN consensus of malnutrition was easily applicable in a population of geriatric hospital patients. Given that the nutritional status of geriatric patients was strongly correlated with the LOS and hospital mortality, the use of this simple and non-time consuming tool is highly recommended in clinical practice.

Association Between Malnutrition and Oral Health in Dutch Nursing Home Residents: Results of the LPZ Study

INTRODUCTION

According to the World Health Organization (WHO) and FDI World Dental Federation (FDI), malnutrition and bad oral health are of great concern to global health, especially among the older population. This study aimed to assess the associations between oral health problems ([artificial] teeth problems, chewing problems, and xerostomia) and malnutrition in residents of somatic and psychogeriatric wards in Dutch nursing homes.

METHODS

Data of the cross-sectional National Prevalence Measurement of Quality of Care study (Landelijke Prevalentiemeting Zorgproblemen study) in the Netherlands were used to evaluate nutritional status and oral health of 3220 residents, aged 65 or older and living in somatic or psychogeriatric wards in Dutch nursing homes. Cox regression was performed to calculate prevalence ratios (PR) of malnutrition among these residents.

RESULTS

Of the total study population, 11.7% were malnourished, 28.6% suffered from xerostomia, 25.6% suffered from chewing problems, and 10.1% experienced problems eating due to (artificial) teeth problems. Within somatic wards, 9.0% were malnourished, whereas 13.2% of residents in psychogeriatric wards were malnourished. Increased risk for malnutrition was found among psychogeriatric residents who had problems with eating due to (artificial) teeth problems (PR 1.6, 95% CI 1.1-2.3).

CONCLUSION

Poor oral health, mostly problems with eating due to (artificial) teeth problems, was associated with an almost twofold risk for malnutrition in older residents in Dutch nursing homes and even more so in psychogeriatric residents than in somatic residents.

Risk factors of refeeding syndrome in malnourished older hospitalized patients

BACKGROUND & AIMS

Despite the high prevalence of malnutrition among older hospitalized persons, it is unknown how many of these malnourished patients are at risk of developing the refeeding syndrome (RFS). In this study, we sought to compare the prevalence and severity of malnutrition among older hospitalized patients with prevalence of known risk factors of RFS.

METHODS

This cross-sectional multicenter-study investigated older participants who were consecutively admitted to the geriatric acute care ward. Malnutrition screening was conducted using Nutritional Risk Screening (NRS-2002), Malnutrition Universal Screening Tool (MUST) and Mini Nutritional Assessment-Short Form (MNA-SF). The National Institute for Health and Clinical Excellence (NICE) criteria were applied for assessing patients at risk of RFS. Weight and height were measured. Degree of weight loss (WL) was obtained by interview. Serum phosphate, magnesium, potassium, sodium, calcium, creatinine and urea were analyzed according to standard procedures.

RESULTS

The study group comprised 342 participants (222 females) with a mean age of 83.1 ± 6.8 and BMI range of 14.7-43.6 kg/m². More participants were assessed at risk of malnutrition using NRS-2002 (n = 253, 74.0%) compared to MUST (n = 170, 49.7%) and MNA-SF (n = 191, 55.8%). Of total participants, 239 (69.9%; 157 females) were considered to be at risk of RFS. Based on NRS-2002, 75.9% (n = 192) of patients at risk of malnutrition are at risk of RFS whereas according to MUST and MNA-SF, 85.9% (n = 146) and 69.1% (n = 132) of patients at risk of malnutrition are exposed to high risk of RFS, respectively. In addition, the prevalence of risk of RFS is significantly increased with higher score of NRS-2002 and MUST and lower score of MNA-SF. In a stepwise multiple regression analysis, disease severity (38.2%), WL in 3 months (20.3%) and BMI (33.3%) mainly explained variance in NRS-2002, MUST and MNA-SF scores, respectively, in patients with risk of RFS.

CONCLUSION

Nearly three-quarters of geriatric hospitalized patients with risk of malnutrition demonstrated significant risk of RFS. Therefore, additional screening for risk of RFS in patients screened for malnutrition appears to be abdicable among this population.

Relationship between the presence of baccalaureate-educated RNs and quality of care: a cross-sectional study in Dutch long-term care facilities

BACKGROUND

Recent evidence suggests that an increase in baccalaureate-educated registered nurses (BRNs) leads to better quality of care in hospitals. For geriatric long-term care facilities such as nursing homes, this relationship is less clear. Most studies assessing the relationship between nurse staffing and quality of care in long-term care facilities are US-based, and only a few have focused on the unique contribution of registered nurses. In this study, we focus on BRNs, as they are expected to serve as role models and change agents, while little is known about their unique contribution to quality of care in long-term care facilities.

METHODS

We conducted a cross-sectional study among 282 wards and 6,145 residents from 95 Dutch long-term care facilities. The relationship between the presence of BRNs in wards and quality of care was assessed, controlling for background characteristics, i.e. ward size, and residents' age, gender, length of stay, comorbidities, and care dependency status. Multilevel logistic regression analyses, using a generalized estimating equation approach, were performed.

RESULTS

57% of the wards employed BRNs. In these wards, the BRNs delivered on average 4.8 min of care per resident per day. Among residents living in somatic wards that employed BRNs, the probability of experiencing a fall (odds ratio 1.44; 95% CI 1.06-1.96) and receiving antipsychotic drugs (odds ratio 2.15; 95% CI 1.66-2.78) was higher, whereas the probability of having an indwelling urinary catheter was lower (odds ratio 0.70; 95% CI 0.53-0.91). Among residents living in psychogeriatric wards that employed BRNs, the probability of experiencing a medication incident was lower (odds ratio 0.68; 95% CI 0.49-0.95). For residents from both ward types, the probability of suffering from nosocomial pressure ulcers did not significantly differ for residents in wards employing BRNs.

CONCLUSIONS

In wards that employed BRNs, their mean amount of time spent per resident was low, while quality of care on most wards was acceptable. No consistent evidence was found for a relationship between the presence of BRNs in wards and quality of care outcomes, controlling for background characteristics. Future studies should consider the mediating and moderating role of staffing-related work processes and ward environment characteristics on quality of care.

Work environment characteristics associated with quality of care in Dutch nursing homes: A cross-sectional study

BACKGROUND

A lack of relationship between direct care staffing levels and quality of care, as found in prior studies, underscores the importance of considering the quality of the work environment instead of only considering staff ratios. Only a few studies, however, have combined direct care staffing with work environment characteristics when assessing the relationship with quality of care in nursing homes.

OBJECTIVES

To examine the relationship between direct care staffing levels, work environment characteristics and perceived quality of care in Dutch nursing homes.

DESIGN

Cross-sectional, observational study in cooperation with the Dutch Prevalence Measurement of Care Problems.

SETTINGS

Twenty-four somatic and 31 psychogeriatric wards from 21 nursing homes in the Netherlands.

PARTICIPANTS

Forty-one ward managers and 274 staff members (registered nurses or certified nurse assistants) from the 55 participating wards.

METHODS

Ward rosters were discussed with managers to obtain an insight into direct care staffing levels (i.e, total direct care staff hours per resident per day). Participating staff members completed a questionnaire on work environment characteristics (i.e., ward culture, team climate, communication and coordination, role model availability, and multidisciplinary collaboration) and they rated the quality of care in their ward. Data were analyzed using multilevel linear regression analyses (random intercept). Separate analyses were conducted for somatic and psychogeriatric wards.

RESULTS

In general, staff members were satisfied with the quality of care in their wards. Staff members from psychogeriatric wards scored higher on the statement 'In the event that a family member had to be admitted to a nursing home now, I would recommend this ward'. A better team climate was related to better perceived quality of care in both ward types (p≤0.020). In somatic wards, there was a positive association between multidisciplinary collaboration and agreement by staff of ward recommendation for a family member (p=0.028). In psychogeriatric wards, a lower score on market culture (p=0.019), better communication/coordination (p=0.018) and a higher rating for multidisciplinary collaboration (p=0.003) were significantly associated with a higher grade for overall quality of care. Total direct care staffing, adhocracy culture, hierarchy culture, as well as role model availability were not significantly related to quality of care.

CONCLUSIONS

Our findings suggest that team climate may be an important factor to consider when trying to improve quality of care. Generating more evidence on which work environment characteristics actually lead to better quality of care is needed.

The Indigenous Australian Malnutrition Project: the burden and impact of malnutrition in Aboriginal Australian and Torres Strait Islander hospital inpatients, and validation of a malnutrition screening tool for use in hospitals-study rationale and protocol

BACKGROUND

Malnutrition is associated with adverse outcomes for hospital inpatients and is a significant economic burden on hospitals. Malnutrition is frequently under-recognised in this setting and valid screening and early diagnosis are important for timely nutritional management. Aboriginal Australian and/or Torres Strait Islander peoples (Indigenous Australians) are likely to be at increased risk of malnutrition due to their disproportionate burden, pattern and age-distribution of chronic diseases. Despite this increased risk, the burden and impact of malnutrition in Indigenous Australians is poorly understood. Furthermore, a suitable screening tool has not been validated for this vulnerable patient group. The aim of this study is to determine the burden of malnutrition, understand its impact, and validate a malnutrition screening tool for Indigenous Australian inpatients.

METHODS

This project involves cross-sectional, prospective cohort and diagnostic validation methodologies to assess the burden and impact of malnutrition and to validate a malnutrition screening tool. A target of 752 adult Indigenous and non-Indigenous Australian inpatients will be recruited across three different public hospitals in the Northern Territory and far north Queensland of Australia. Cross-sectional data collection will be used to determine the prevalence of malnutrition using the Subjective Global Assessment and to stratify participants based on the International Consensus Guideline Committee malnutrition aetiology-diagnostic framework. Subjects will then be followed prospectively to measure short and long-term health outcomes such as length of hospital stay, in-hospital mortality, 30-day and 6-month readmission rates. Finally, the utility of a new screening tool, the Australian Nutrition Tool, will be assessed against an existing screening tool, the malnutrition screening tool, used in these settings and the malnutrition reference standard, the Subjective Global Assessment.

DISCUSSION

Indigenous Australians continue to experience poorer levels of health than non-Indigenous Australians and issues such as food insecurity, poor diet, and a disproportionate burden of chronic disease play a key contributing role for malnutrition in Indigenous Australians. To improve the health and hospital outcomes of Indigenous and non-Indigenous Australians, it is important that patients are routinely screened using a validated screening tool. It is also imperative that the burden and impact of malnutrition is properly understood, and fully appreciated, so that early and appropriate nutritional management can be provided to this group of hospital patients.

Hospital malnutrition in Latin America: A systematic review

BACKGROUND

Disease-related malnutrition is a major public health issue in both industrialised and emerging countries. The reported prevalence in hospitalised adults ranges from 20% to 50%. Initial reports from emerging countries suggested a higher prevalence compared with other regions, with limited data on outcomes and costs.

METHODS

We performed a systematic literature search for articles on disease-related malnutrition in Latin American countries published between January 1995 and September 2014. Studies reporting data on the prevalence, clinical outcomes, or economic costs of malnutrition in an adult (≥18 years) inpatient population with a sample size of ≥30 subjects were eligible for inclusion. Methodological quality of the studies was assessed by two independent reviewers using published criteria.

RESULTS

We identified 1467 citations; of these, 66 studies including 29 ,474 patients in 12 Latin American countries met the criteria for inclusion. There was considerable variability in methodology and in the reported prevalence of disease-related malnutrition; however, prevalence was consistently in the range of 40%-60% at the time of admission, with several studies reporting an increase in prevalence with increasing duration of hospitalisation. Disease-related malnutrition was associated with an increase in infectious and non-infectious clinical complications, length of hospital stay, and costs.

CONCLUSION

Disease-related malnutrition is a highly prevalent condition that imposes a substantial health and economic burden on the countries of Latin America. Further research is necessary to characterise screening/assessment practices and identify evidence-based solutions to this persistent and costly public health issue.

Undernutrition screening survey in 564,063 patients: patients with a positive undernutrition screening score stay in hospital 1.4 d longer

BACKGROUND

Undernutrition is a common complication of disease and a major determinant of hospital stay outcome. Dutch hospitals are required to screen for undernutrition on the first day of admission.

OBJECTIVE

We sought to determine the prevalence of the screening score "undernourished" with the use of the Short Nutritional Assessment Questionnaire (SNAQ) or Malnutrition Universal Screening Tool (MUST) and its relation to length of hospital stay (LOS) in the general hospital population and per medical specialty.

DESIGN

We conducted an observational cross-sectional study at 2 university, 3 teaching, and 8 general hospitals. All adult inpatients aged ≥18 y with an LOS of at least 1 d were included. Between 2007 and 2014, the SNAQ/MUST score, admitting medical specialty, LOS, age, and sex of each patient were extracted from the digital hospital chart system. Linear regression analysis with ln(LOS) as an outcome measure and SNAQ ≥3 points/MUST ≥2 points, sex, and age as determinant variables was used to test the relation between SNAQ/MUST score and LOS.

RESULTS

In total, 564,063 patients were included (48% males and 52% females aged 62 ± 18 y). Of those, 74% (419,086) were screened with SNAQ and 26% (144,977) with MUST, and 13.7% (SNAQ) and 14.9% (MUST) of the patients were defined as being undernourished. Medical specialties with the highest percentage of the screening score of undernourished were geriatrics (38%), oncology (33%), gastroenterology (27%), and internal medicine (27%). Patients who had an undernourished screening score had a higher LOS than did patients who did not (median 6.8 compared with 4.0 d; P < 0.001). Regression analysis showed that a positive SNAQ/MUST score was significantly associated with LOS [SNAQ: +1.43 d (95% CI: 1.42, 1.44 d), P < 0.001; MUST: +1.47 d (95% CI: 1.45, 1.49 d), P < 0.001].

CONCLUSIONS

This study provides benchmark data on the prevalence of undernutrition, including more than half a million patients. One out of 7 patients was scored as undernourished. For geriatrics, oncology, gastroenterology, and internal medicine, this ratio was even greater (1 out of 3–4). Hospital stay was 1.4 d longer among undernourished patients than among those who were well nourished.

Factors associated with (risk of) undernutrition in community-dwelling older adults receiving home care: a cross-sectional study in the Netherlands

Objective

It is generally thought that causes of undernutrition are multifactorial, but there are limited quantitative studies performed. We therefore examined a wide range of potential factors associated with undernutrition in community-dwelling older adults.

Design

Cross-sectional study.

Setting

Community-dwelling older adults (≥65 years) receiving home care in the Netherlands.

Subjects

Data on potential factors associated with (risk of) undernutrition were collected among 300 older adults. Nutritional status was assessed by the SNAQ65+ instrument. Undernutrition was defined as mid-upper arm circumference <25 cm or unintentional weight loss of ≥4 kg in 6 months. Being at risk of undernutrition was defined as having poor appetite and inability to walk up and down stairs of fifteen steps, without resting.

Results

Of all participants, ninety-two (31·7 %) were undernourished and twenty-four (8·0 %) were at risk of undernutrition. Based on multivariate logistic regression analyses, the statistically significant factors associated with (risk of) undernutrition (P<0·05) were: unable to go outside (OR=5·39), intestinal problems (OR=2·88), smoking (OR=2·56), osteoporosis (OR=2·46), eating fewer than three snacks daily (OR=2·61), dependency in activities of daily living (OR=1·21), physical inactivity (OR=2·01), nausea (OR=2·50) and cancer (OR=2·84); a borderline significant factor was depression symptoms (OR=1·83, P=0·053).

Conclusions

The study suggests that (risk of) undernutrition is a multifactorial problem and that associated factors can be found in several domains. These findings may support the development of intervention trials for the prevention and treatment of undernutrition in community-dwelling older adults.

The Graz Malnutrition Screening (GMS): a new hospital screening tool for malnutrition

Despite the significant impact of malnutrition in hospitalised patients, it is often not identified by clinical staff in daily practice. To improve nutritional support in hospitals, standardised routine nutritional screening is essential. The Graz Malnutrition Screening (GMS) tool was developed for the purpose of malnutrition risk screening in a large hospital setting involving different departments. It was the aim of the present study to validate the GMS against Nutritional Risk Screening (NRS) and Mini Nutritional Assessment-short form (MNA-sf) in a randomised blinded manner. A total of 404 randomly selected patients admitted to the internal, surgical and orthopaedic wards of the University Hospital Graz were screened in a blinded manner by different raters. Concurrent validity was determined by comparing the GMS with the NRS and in older patients (70+ years) with the MNA-sf additionally. According to GMS, 31·9 or 28·5 % of the admitted patients were categorised as at ‘risk of malnutrition’ (depending on the rater). According to the reference standard of NRS, 24·5 % of the patients suffered from malnutrition. Pearson’s r values of 0·78 compared with the NRS and 0·84 compared with the MNA showed strong positive correlations. Results of accuracy (0·85), sensitivity (0·94), specificity (0·77), positive predictive value (0·76) and negative predictive value (0·95) of GMS were also very high. Cohen’s κ for internal consistency of the GMS was 0·82. GMS proves to be a valid and reliable instrument for the detection of malnutrition in adult patients in acute-care hospitals.

Evaluation of the efficacy of nutritional screening tools to predict malnutrition in the elderly at a geriatric care hospital

BACKGROUND/OBJECTIVES

Malnutrition in the elderly is a serious problem, prevalent in both hospitals and care homes. Due to the absence of a gold standard for malnutrition, herein we evaluate the efficacy of five nutritional screening tools developed or used for the elderly.

SUBJECTS/METHODS

Elected medical records of 141 elderly patients (86 men and 55 women, aged 73.5 ± 5.2 years) hospitalized at a geriatric care hospital were analyzed. Nutritional screening was performed using the following tools: Mini Nutrition Assessment (MNA), Mini Nutrition Assessment-Short Form (MNA-SF), Geriatric Nutritional Risk Index (GNRI), Malnutrition Universal Screening Tool (MUST) and Nutritional Risk Screening 2002 (NRS 2002). A combined index for malnutrition was also calculated as a reference tool. Each patient evaluated as malnourished to any degree or at risk of malnutrition according to at least four out of five of the aforementioned tools was categorized as malnourished in the combined index classification.

RESULTS

According to the combined index, 44.0% of the patients were at risk of malnutrition to some degree. While the nutritional risk and/or malnutrition varied greatly depending on the tool applied, ranging from 36.2% (MUST) to 72.3% (MNA-SF). MUST showed good validity (sensitivity 80.6%, specificity 98.7%) and almost perfect agreement (k = 0.81) with the combined index. In contrast, MNA-SF showed poor validity (sensitivity 100%, specificity 49.4%) and only moderate agreement (k = 0.46) with the combined index.

CONCLUSIONS

MNA-SF was found to overestimate the nutritional risk in the elderly. MUST appeared to be the most valid and useful screening tool to predict malnutrition in the elderly at a geriatric care hospital.

Malnutrition in Community-Dwelling Elderly in Turkey: A Multicenter, Cross-Sectional Study

BACKGROUND

This study aimed to investigate the prevalence of malnutrition and explore the somatic, psychological, functional, and social or lifestyle characteristics linked to malnutrition in elderly people at a hospital in Turkey.

MATERIAL AND METHODS

This study included 1030 patients older than 65 years of age who were seen at the internal medicine and geriatrics outpatient clinics of the study centers in Istanbul, Ankara, Duzce, Corum, Mardin, Malatya, and Diyarbakir provinces between January and December 2014. All patients underwent Mini Nutritional Assessment (MNA) and Geriatric Depression Scale (GDS) tests via one-on-one interview method. The demographic properties of the patients were also recorded during this interview.

RESULTS

Among 1030 patients included in this study, 196 (19%) had malnutrition and 300 (29.1%) had malnutrition risk. The malnutrition group and the other groups were significantly different with respect to mean GDS score, income status, educational status, the number of children, functional status (ADL, IADL), the number of patients with depression, and the number of comorbid disorders. According to the results of the logistic regression analysis, age (OR=95% CI: 1.007-1.056; p=0.012), BMI (OR=95% CI: 0.702-0.796; p<0.001), educational status (OR=95% CI: 0.359-0.897; p=0.015), comorbidity (OR=95% CI: 2.296-5.448; p<0.001), and depression score (OR=95% CI: 1.104-3.051; p=0.02) were independently associated with malnutrition.

CONCLUSIONS

Our study demonstrates that age, depression, BMI, comorbidity, and the educational status were independently associated with malnutrition in an elderly population.

Cost and effectiveness of omega-3 fatty acid supplementation in Chinese ICU patients receiving parenteral nutrition

Background and objectives

Clinical evidence supports the use of omega-3 polyunsaturated fatty acid (PUFA)-enriched lipid emulsions in place of standard lipid emulsions in parenteral nutrition (PN) for intensive care unit (ICU) patients, but uptake may be limited by higher costs. We compared clinical and economic outcomes for these two types of lipid emulsion in the Chinese ICU setting.

Methods

We developed a pharmacoeconomic discrete event simulation model, based on efficacy data from an international meta-analysis and patient characteristics, resource consumption, and unit costs from a Chinese institutional setting. Probabilistic sensitivity analyses were undertaken to assess the effects of uncertainty around input parameters. Model predictive validity was assessed by comparing results with data observed in a patient subset not used in the modeling.

Results

The model predicted that omega-3 PUFA-enriched emulsion (Omegaven^® 10% fish oil emulsion) would dominate standard lipid emulsions, with better clinical outcomes and lower overall health care costs (mean savings ~10,000 RMB), mainly as a result of faster recovery and shorter hospital stay (by ~6.5 days). The external validation process confirmed the reliability of the model predictions.

Conclusion

Omega-3 PUFA-enriched lipid emulsions improved clinical outcome and decreased overall costs in Chinese ICU patients requiring PN.

Fight against malnutrition: The results of a 2006-2012 prospective national and global nutritionDay survey

BACKGROUND

The nutritionDay (nD) initiative has been promoted by the European Society for Clinical Nutrition and Metabolism (ESPEN) to assess and audit the nutritional status of hospitalized patients, as well as to promote awareness. Israel has been participating annually in this project since 2006.

OBJECTIVES

To evaluate the proportion of malnourished patients in Israel in comparison with the rest of the world.

METHODS

Data were collected by staff members and the hospitalization outcomes were followed up at day 30. The data were analyzed by the Vienna coordinating center, using "my SQL" (Structured Query Language), an open source relational database management system and analyzed, using SAS (Statistical Analysis System) version 9.2.

RESULTS

In Israel, 2303 patients (in 114 various medical specialty units) were included in the study during a 7-year survey, while 4316 units recruited 91,351 patients in the world (W), between 2006 and 2012, The median age of patients was 68 years, with 44% of females and BMI of 27 ± 6 (25 in W). Israel had a higher proportion of nutrition care teams per patient (in 88% of the units) than W (71%) (p < 0.05). 43% of the patients had a weight loss within the last 3 months prior to admission (same for W); 36.7% described a decrease in eating more than 50% of their normal food intake (21.3% in W). Food intake at nD showed that 51.4% of the patients ate half to nothing of the served meal (56.2% in W). In Israel, more patients received hospital modified diets (13% vs. 8.2% in W), but less supplements (5.7% vs. 8.3% in W) or enteral/parenteral nutrition (9.0% vs. 13.5% in W, p < 0.05). Length of hospital stay was shorter in Israel (11 days vs. 14 days in W, p < 0.05) and mortality was similar (3.9% vs. 3.8% in W).

CONCLUSION

Malnutrition of hospitalized patients in Israel was found comparable to the rest of the world. However, in Israel in spite of the higher nutrition staff member/patient ratio there was no increase in the administration of supplements or artificial nutrition to malnourished patients in the surveyed units. Also, the length of hospital stay was shorter and was not associated with an increase in mortality.

That's why I take my ONS. Means-end chain as a novel approach to elucidate the personally relevant factors driving ONS consumption in nutritionally frail elderly users

Oral nutritional supplements (ONS) are a recommended form of nutritional intervention for older malnourished persons when a 'food first' approach and/or food fortification prove ineffective. The efficacy of ONS will depend on, amongst other factors, whether persons do, or do not, consume their prescribed amount. Factors influencing ONS consumption can be product, context, or person related. Whereas product and context have received some attention, little is known about the person factors driving ONS consumption. In addition, the relative importance of the product, context, and person factors to ONS consumption is not known. Using the means-end chain (MEC) method, the current study elucidated personally relevant factors (product, context, and person factors) related to ONS consumption in two groups of older nutritionally frail ONS users: community-dwelling persons and care home residents with mainly somatic disorders. To our knowledge, the current work is the first to apply the MEC method to study older nutritionally frail ONS users. Forty ONS users (n = 20 per group) were recruited via healthcare professionals. The level of frailty was assessed using the FRAIL scale. Both groups were interviewed for 30 to 45 minutes using the soft laddering technique. The laddering data were analysed using LadderUX software™. The MEC method appeared to work well in both groups. The majority of the participants took ONS on their doctor's or dietician's prescription as they trusted their advice. The community-dwelling group took ONS to prolong their independence, whereas the care home group reported values that related more to small improvements in quality of life. In addition, care home residents perceived themselves as dependent on their caregiver for their ONS arrangements, whereas this dependence was not reported by community-dwelling persons. Key insights from this work will enable doctors and dieticians to customize their nutritional interventions to ONS users' personal needs and thus positively impact health outcomes.

Determinants of protein-energy malnutrition in community-dwelling older adults: a systematic review of observational studies

Protein-energy malnutrition is associated with numerous poor health outcomes, including high health care costs, mortality rates and poor physical functioning in older adults. This systematic literature review aims to identify and provide an evidence based overview of potential determinants of protein-energy malnutrition in community-dwelling older adults. A systematic search was conducted in PUBMED, EMBASE, CINAHL and COCHRANE from the earliest possible date through January 2013. Observational studies that examined determinants of protein-energy malnutrition were selected and a best evidence synthesis was performed to summarize the results. In total 28 studies were included in this review from which 122 unique potential determinants were derived. Thirty-seven determinants were examined in sufficient number of studies and were included in a best evidence synthesis. The best evidence score comprised design (cross-sectional, longitudinal) and quality of the study (high, moderate) to grade the evidence level. Strong evidence for an association with protein-energy malnutrition was found for poor appetite, and moderate evidence for edentulousness, having no diabetes, hospitalization and poor self-reported health. Strong evidence for no association was found for anxiety, chewing difficulty, few friends, living alone, feeling lonely, death of spouse, high number of diseases, heart failure and coronary failure, stroke (CVA) and the use of anti-inflammatory medications. This review shows that protein-energy malnutrition is a multifactorial problem and that different domains likely play a role in the pathway of developing protein-energy malnutrition. These results provide important knowledge for the development of targeted, multifactorial interventions that aim to prevent the development of protein-energy malnutrition in community-dwelling older adults.

Increased number of chews during a fixed-amount meal suppresses postprandial appetite and modulates glycemic response in older males

Aging is associated with a reduction in appetite. Older adults require a higher number of chews to form a bolus before swallowing. However, whether this ingestive behavior contributes to the reduced appetite in this population is unknown. Fifteen males aged 65 years or older participated in this randomized cross-over trial and attended two test sessions. After an overnight fast, they consumed a fixed-amount meal (2050 kJ) by chewing each portion of food 15 or 40 times before swallowing. Subjective appetite was measured using visual analogue scales at regular intervals for 3 h after completion of the meal. Blood samples were collected at the same time for measurement of glucose, insulin, and glucose-dependent insulinotropic peptide (GIP). Participants were provided an ad libitum meal 3 h later. Compared with 15 chews, chewing food 40 times before swallowing resulted in significantly lower postprandial hunger (P=0.003), preoccupation with food (P<0.001), and desire to eat (P<0.001). Plasma concentrations of glucose, insulin, and GIP were significantly higher at meal completion when 40 chews were made (all P<0.01), and became significantly lower during the late postprandial period (all P<0.05). Food intake at the subsequent ad libitum meal did not differ significantly between test sessions. Our findings suggested that increased number of chews reduced postprandial hunger and desire to eat, and modulated glucose metabolism in older males. The number of chews made during a fixed-amount meal may influence short-term appetite; how this ingestive behavior contributes to energy balance in the long term warrants further investigation.

Which characteristics of nursing home residents influence differences in malnutrition prevalence? An international comparison of The Netherlands, Germany and Austria

Prevalence rates of malnutrition vary considerably internationally, partly due to differences in measurement methodology and instruments. In the present study, the same measurement methodology and instruments were used in The Netherlands, Germany and Austria. The aim of the present study was to investigate whether resident characteristics influence possible differences in malnutrition prevalence between countries. The study followed a cross-sectional, multi-centre design that measured malnutrition in nursing home residents from The Netherlands, Germany and Austria. Resident data were gathered using a standardised questionnaire. Malnutrition was operationalised using BMI, unintentional weight loss and nutritional intake. Data were analysed using an association model. The prevalence rates of malnutrition in The Netherlands, Germany and Austria were 18·3, 20·1 and 22·5 %, respectively. The multivariate generalised estimating equation (GEE) logistic regression analysis showed that sex, age, care dependency, the mean number of diseases and some specific diseases were influencing factors for whether the resident was malnourished or not. The OR of malnutrition in the three countries declined after including the influencing factors resulting from the multivariate GEE analysis. The present study reveals that differences in the prevalence rates of malnutrition in nursing homes in The Netherlands, Germany and Austria are influenced by different resident characteristics. Since other country-related factors could also play an important role in influencing differences in the prevalence rates of malnutrition between the countries (structural and process factors of malnutrition care policy). We recommend the investigation of these factors in future studies.
