Prevalence of Malnutrition or Risk in Residents in Long Term Care: Comparison of Four Tools

Assessing Dysphagia in the Adult

This article explores the landscape of dysphagia assessment in adults. Dysphagia, a complex condition affecting the lifespan and many health conditions, significantly compromises individuals' quality of life. Dysphagia is often underdiagnosed, emphasizing the need for comprehensive assessment methods to ensure timely and accurate intervention. It encompasses clinical history, physical examination, clinical and instrumental swallow evaluations. Procedures within each of these modalities are reviewed, highlighting strengths, limitations, and contribution toward a complete understanding of dysphagia, ultimately guiding effective intervention strategies for improved patient outcomes.

Prevention and Treatment of Malnutrition in Older Adults Living in Long-Term Care or the Community: An Evidence-Based Nutrition Practice Guideline

Malnutrition in older adults can decrease quality of life and increase risk of morbidities and mortality. Accurate and timely identification of malnutrition, as well as subsequent implementation of effective interventions, are essential to decrease poor outcomes associated with malnutrition in older adults. The Academy of Nutrition and Dietetics Evidence Analysis Center conducted a systematic review of the literature to develop an evidence-based nutrition practice guideline for the prevention and treatment of malnutrition in older adults. The objective of this guideline was to provide evidence-based recommendations to identify, prevent, or treat protein-energy malnutrition in older adults (mean age ≥65 years) living in long-term care and community settings. This guideline provides 11 nutrition recommendations to inform shared decision making among dietitians, members of the health care team, family members or caregivers, and older adults living in long-term care or the community to prevent or treat malnutrition. Topics include dietitian effectiveness, nutrition assessment tools, oral nutrition supplements, food fortification, and home-delivered and congregate meals. Guideline implementation should include consideration of the importance of comprehensive individualized nutrition care for older adults. Future research is needed to address gaps that were identified related to the validity, reliability, and feasibility of nutrition assessment tools, as well as the effectiveness of dietitian interventions on outcomes of interest in older adults living in long-term care and the community.

The five aspects mealtime environment observation instrument for assessing mealtime environments in nursing homes: Development and validation

AIMS AND OBJECTIVES

To further develop and validate the Mealtime instrument, an observational instrument for assessing mealtime environments in nursing homes originating from the theoretical framework: Five Aspects Meal Model (FAMM).

METHODOLOGICAL DESIGN AND JUSTIFICATION

A mealtime experience is significant for a sense of well-being. In nursing homes, residents' personal preferences, combined with their diagnoses and different stages of illness, influence their mealtime experience and provide a complexity that has been found difficult to assess. Using FAMM, a theoretical framework as its base, this study, attempts to look at different parts of the mealtime environment. FAMM structures the mealtime environment in to five aspects: room, meeting, product, management control system and atmosphere. This study's design includes instrument development and validation.

ETHICAL ISSUES AND APPROVAL

This study has been approved by the Swedish Ethical Review Authority (dnr 2019-05477).

DESIGN

Methodological study.

RESEARCH METHOD

An existing instrument, the Mealtime instrument with FAMM as a theoretical framework, was used as a foundation for the development of the Five Aspects Mealtime Environment Observation Instrument (FAME-OI). Content validity index (CVI) was used to validate FAME-OI.

RESULTS

FAME-OI's item-CVI, scale-CVI and modified Kappa displayed high validity. Changes were made in its structure and phrasing. These developments resulted in having a distinct structure in FAME-OI, in reference to FAMM.

CONCLUSION

FAME-OI is applicable for clinical use in nursing homes and in research; however, adjustments may be needed before its use in other health care facilities.

Factors associated with dietitian referrals to support long-term care residents advancing towards the end of life

BACKGROUND

Dietitians are central members of the multidisciplinary long-term care (LTC) healthcare team. The overall aim of this current investigation is to gain a better understanding of dietitian involvement in LTC resident's end-of-life care via referrals.

METHODS

Retrospective chart reviews for 164 deceased residents (mean age = 88.3 ± 7.3; 61% female) in 18 LTC homes in Ontario, Canada, identified dietitian referrals and documented eating challenges recorded over 2-week periods at four time points (i.e., 6 months, 3 months, 1 month and 2 weeks) prior to death. Nutrition care plans at the beginning of these time points were also noted. Logistic mixed effects regression models identified time-varying predictors of dietitian referrals. Bivariate tests identified associations between nutrition orders and dietitian referrals that occurred in the last month of life.

RESULTS

Nearly three-quarters (73%) of participants had at least one dietitian referral across the four observations. Referrals increased significantly with proximity to death; 45% of residents had a referral documented in the last 2 weeks of life. Dietitian referrals were associated with the number of eating challenges (odds ratio [OR] = 1.42, 95% confidence interval [CI] = 1.27, 1.58). Comfort-focused nutrition care orders were significantly more common when a dietitian was referred (25%) compared with when a dietitian was not referred (12%) in the final month of life (p = 0.04).

CONCLUSIONS

Our findings suggest that dietitians are involved in end-of-life and comfort-focused nutrition care initiatives, yet they are not engaged consistently for this purpose. This presents a significant opportunity for dietitians to upskill and champion palliative approaches to nutrition care within the multidisciplinary LTC team.

How Useful are Mid-Arm and Calf Circumferences to Indicate Reduced Muscle Mass in Order to Recognize GLIM-Defined Malnutrition in Elderly Individuals?

AIMS

The aim of this study was to estimate cutoff values of mid-upper arm circumference (MUAC) and calf circumference (CC) for reduced muscle mass and analyze their accuracy in identifying malnutrition among individuals of 65 years of age or older in Bosnia and Herzegovina.

MATERIALS AND METHODS

The study is a secondary analysis dataset assessing nutritional risk and malnutrition among 446 community-dwellers and nursing home residents in Bosnia and Herzegovina. Malnutrition assessment included phenotypic criterions (weight loss, low body mass index, and reduced muscle mass) and etiologic criterions (inadequate food intake, disease-related inflammation, or albumin levels) according to recommendations of the Global Leadership Initiative on Malnutrition (GLIM). Receiver operating curves were used to calculate MUAC and CC's cutoff values as compared to the Mini Nutritional Assessment (MNA).

RESULTS

The optimal cutoff value for MUAC in men was 24 cm (AUC = 0.910, sensitivity 100%, specificity 77%), and in women 23 cm (AUC = 0.792, sensitivity 64%, specificity 83%). Optimal cutoff value of CC in men was 31 cm (AUC = 0.818, sensitivity 100%, specificity 67%) and in women 29 cm (AUC = 0.882, sensitivity 86%, specificity 74%). Two hundred fifty nine elderly individuals were categorized as malnourished/at risk for malnutrition per MNA. The prevalence of malnutrition based on GLIM criteria ranged from 19% to 30%.

CONCLUSIONS

The study suggested that MUAC and CC may be used as the alternative indicators of muscle mass when other assessment methods are unavailable. Future validation and reliability studies for GLIM using anthropometric parameters as a proxy of reduced muscle mass are needed.

Nutrition and Non-Nutrition-Related Challenges Predict Time to Death in Long-Term Care Residents: A Retrospective Chart Review

Purpose

Signals of end-of-life decline observed in daily habits, such as mealtime participation, are important for moving towards comfort-focused goals of care in the final months of life of long-term care (LTC) residents. It is unclear how eating issues observed in real-time in LTC homes are used as indicators of suspected end of life. The study quantifies nutrition and key non-nutrition related signals (eg, general decline, unstable vitals) documented to describe end-of-life decline and the subsequent time to death.

Patients and Methods

A retrospective chart review identified the first documented conversation where end-of-life decline was considered by members of the care team (eg, nurses, physicians, dietitian, family member) for 76 randomly selected decedents from 9 LTC homes in southwestern Ontario, Canada. Time (days) to death was calculated. A directed content analysis of the free-text description of the suspected end-of-life decline was used to categorize signals. Cox proportional hazards regression analysis tested the risk of mortality associated with each categorized signal.

Results

Time to death of residents (mean age = 88 ± 7 years; 60% female) from the first documentation of potential end-of-life decline ranged from 0 days to over 2 years prior to death (median = 27.5 days). Seven nutrition-related and 18 non-nutrition related signals were identified. Swallowing difficulty (HR = 2.99; 95% CI = 1.41, 6.33), cognitive decline (HR = 0.40; 95% CI = 0.20, 0.77), delirium (HR = 13.23; 95% CI = 1.57, 111.69), and cancer (HR = 0.18; 95% CI = 0.07, 0.48) were associated with time to death.

Conclusion

This study provides insight into the signals used by care providers in LTC to suspect that residents are declining towards the end of life and identifies four signals that were associated with time to death. When identified by care providers as indicators of end-of-life decline, swallowing difficulty and delirium predicted a shorter time to death, while cancer and cognitive decline predicted a longer time to death. Recognition of nutrition and non-nutrition related signals may be leveraged to systematically introduce timely comfort care conversations.

Prevalence of Malnutrition in People with Dementia in Long-Term Care: A Systematic Review and Meta-Analysis

Dementia is a common syndrome in older people. Dementia alters eating behaviors, hunger and thirst cues, swallow function, ability to self-feed, and recognition and interest in food. There is significant variation in the reported prevalence of malnutrition among older people who live in long-term care. The aim was to conduct a systematic literature review and meta-analysis of the prevalence of malnutrition in those with dementia living in long-term care using a validated nutrition assessment tool. Scopus, Web of Science, CINAHL, and Medline were searched. A random effects model was used to determine the prevalence and risk of malnutrition. Data were retrieved from 24 studies. Most of the studies were from Europe or South Asia. The prevalence of malnutrition ranged from 6.8 to 75.6%, and the risk of malnutrition was 36.5-90.4%. The pooled prevalence of malnutrition in those with dementia in long-term care was 26.98% (95% CI 22.0-32.26, p < 0.0001, I² = 94.12%). The pooled prevalence of the risk of malnutrition in those with dementia was 57.43% (95% CI 49.39-65.28, p < 0.0001, I² = 97.38%). Malnutrition is widespread in those with dementia living in long-term care. Further research exploring malnutrition in other industrialized countries using validated assessment tools is required.

The Provision of Texture-Modified Foods in Long-term Care Facilities by Health Professionals: Protocol for a Scoping Review

BACKGROUND

Malnutrition among older adults with dysphagia is common. Texture-modified foods (TMFs) are an essential part of dysphagia management. In long-term care (LTC) facilities, health professionals have implemented TMFs, but their application has not been fully elucidated, making them heterogeneous.

OBJECTIVE

We aim to explore the implementation of TMFs in LTC facilities, particularly focusing on the role of health professionals in nutritional care involving TMFs (eg, deciding the type of food, preparing and giving the food, and evaluating the outcomes).

METHODS

A scoping review using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodological approach will be performed. A comprehensive search for published literature will be systematically performed in PubMed, CINAHL, MEDLINE, ProQuest, PsycINFO, and Science Citation Index (Web of Science). Data screening and extraction will be performed by 2 reviewers independently. The studies included will be synthesized, summarized, and reported, following the preferred reporting items of the Mixed Methods Appraisal Tool. Our review will consider the following study designs: mixed methods, quantitative, and qualitative. Studies with patients who are not older adults will be excluded.

RESULTS

Data extraction will be completed by February 2023. Data presentation and analyses will be completed by April 2023, and the final outcomes will be completed by June 2023. The study findings will be published in a peer-reviewed journal.

CONCLUSIONS

Our scoping review will consider studies related to TMF interventions for older adults in LTC residential facilities, with no exclusion restrictions based on country, gender, or comorbidities. Studies on interventions that address TMF-related issues, such as deciding the type of food, preparing and giving the food, and evaluating the outcomes, are qualified for inclusion.

Characterizing Canadian long-term care home consumed foods and their inflammatory potential: a secondary analysis

BACKGROUND

Nutrient dense food that supports health is a goal of food service in long-term care (LTC). The objective of this work was to characterize the "healthfulness" of foods in Canadian LTC and inflammatory potential of the LTC diet and how this varied by key covariates. Here, we define foods to have higher "healthfulness" if the are in accordance with the evidence-based 2019 Canada's Food Guide, or with comparatively lower inflammatory potential.

METHODS

We conducted a secondary analysis of the Making the Most of Mealtimes dataset (32 LTC homes; four provinces). A novel computational algorithm categorized food items from 3-day weighed food records into 68 expert-informed categories and Canada's Food Guide (CFG) food groups. The dietary inflammatory potential of these food sources was assessed using the Dietary Inflammatory Index (DII). Comparisons were made by sex, diet texture, and nutritional status.

RESULTS

Consumption patterns using expert-informed categories indicated no single protein or vegetable source was among the top 5 most commonly consumed foods. In terms of CFG's groups, protein food sources (i.e., foods with a high protein content) represented the highest proportion of daily calorie intake (33.4%; animal-based: 31.6%, plant-based: 1.8%), followed by other foods (31.3%) including juice (9.8%), grains (25.0%; refined: 15.0%, whole: 10.0%), and vegetables/fruits (10.3%; plain: 4.9%, with additions: 5.4%). The overall DII score (mean, IQR) was positive (0.93, 0.23 to 1.75) indicating foods consumed tend towards a pro-inflammatory response. DII was significantly associated with sex (female higher; p<0.0001), and diet (minced higher; p=0.036).

CONCLUSIONS

"Healthfulness" of Canadian LTC menus may be enhanced by lowering inflammatory potential to support chronic disease management through further shifts from refined to whole grains, incorporating more plant-based proteins, and moving towards serving plain vegetables and fruits. However, there are multiple layers of complexities to consider when optimising foods aligned with the CFG, and shifting to foods with anti-inflammatory potential for enhanced health benefits, while balancing nutrition and ensuring sufficient food and fluid intake to prevent or treat malnutrition.

Weight Loss and Weight Gain: Multi-Level Determinants Associated with Resident 3-Month Weight Change in Long-Term Care

This study examined factors associated with weight change in 535 residents in 32 long term care homes where 3-month weight records were available. Trained researchers and standardized measures (e.g., nutrition status, food intake, home characteristics) were used to collect data; weight change was defined as ±2.5%. Just over 25% of the sample lost and 21% gained weight. Weight stability was compared to loss or gain. Weight loss was associated with being male, malnourished (MNA-SF or BMI <25), energy and protein intake and oral nutritional supplement use, while weight gain was associated with being female, and a physically (e.g., less noise) and socially supportive dining room. Weight stability was associated with better cognition. A high proportion of residents had a significant weight change in 3 months. Modifiable factors associated with weight stability or gain suggest focusing interventions that promote food intake and improve the mealtime environment.

Harmonization and standardization of malnutrition screening for all adults - A systematic review initiated by the Norwegian Directorate of Health

BACKGROUND & AIMS

The Norwegian Directorate of Health has identified a need to harmonize and standardize the malnutrition screening practice in Norwegian hospitals and primary health care settings, in order to provide a seamless communication of malnutrition screening along the patient pathway. Our aim was to perform a systematic review of the validity and reliability of screening tools used to identify risk of malnutrition across health care settings, diagnoses or conditions and adult age groups, as a first step towards a national recommendation of one screening tool.

METHODS

A systematic literature search for articles evaluating validity, agreement, and reliability of malnutrition screening tools, published up to August 2020, was conducted in: MEDLINE, Embase, APA PsycInfo, Cinahl, Cochrane Databases, Web of Science, Epistemonikos, SveMed+, and Norart. The systematic review was registered in PROSPERO (CRD42022300558). For critical appraisal of each included article, the Quality Criteria Checklist by The Academy of Nutrition and Dietetics was used.

RESULTS

The review identified 105 articles that fulfilled the inclusion and exclusion criteria. The most frequently validated tools were Mini Nutritional Assessment short form (MNA), Malnutrition Universal Screening Tool (MUST), Malnutrition Screening Tool (MST), and Nutritional Risk Screening 2002 (NRS-2002). MNA, MST and NRS-2002 displayed overall moderate validity, and MUST low validity. All four tools displayed low agreement. MST and MUST were validated across health care settings and age groups. In general, data on reliability was limited.

CONCLUSIONS

The screening tools MST and NRS-2002 displayed moderate validity for the identification of malnutrition in adults, of which MST is validated across health care settings. In addition, MNA has moderate validity for the identification of malnutrition in adults 65 years or older.

A Comparison of Dietary Intake and Nutritional Status between Aged Care Residents Consuming Texture-Modified Diets with and without Oral Nutritional Supplements

Oral nutritional supplements (ONS) are high-energy and protein-rich nutrition drinks that are commonly prescribed to individuals with compromised nutritional status. Aged care residents requiring texture-modified diets are exposed to poor oral intake and malnutrition. This study aimed to investigate the dietary intake and nutritional status of residents consuming texture-modified diets with and without ONS. This multicentre cross-sectional study included 85 residents consuming texture-modified diets (86.0 ± 8.7 y; n = 46 requiring ONS and n = 39 without ONS). A one-day dietary record was completed using a validated visual plate waste estimation method. To determine the adequacy, nutrition intake was then calculated using FoodWorks (Xyris Ltd., Brisbane, Australia) and compared to the recommended dietary intake for Australia and New Zealand. The Mini-Nutritional Assessment Short Form was collected to assess nutritional status. Residents receiving ONS had significantly higher energy, protein, carbohydrates and fat intake than those who did not consume ONS (p < 0.05). No significant differences were found in saturated fat, fibre or sodium intake. With the administration of ONS, residents were able to meet their protein requirement but fell short of their energy and carbohydrates requirements. Both groups had inadequate fibre intake and a high saturated fat intake. A total of 48% of the residents were at risk of malnutrition and 38% were malnourished. Aged care residents requiring texture-modified diets are at high risk of malnutrition as a result of inadequate dietary intake. Administration of ONS may be an effective strategy to optimise nutrition intake.

Automated food intake tracking requires depth-refined semantic segmentation to rectify visual-volume discordance in long-term care homes

Malnutrition is a multidomain problem affecting 54% of older adults in long-term care (LTC). Monitoring nutritional intake in LTC is laborious and subjective, limiting clinical inference capabilities. Recent advances in automatic image-based food estimation have not yet been evaluated in LTC settings. Here, we describe a fully automatic imaging system for quantifying food intake. We propose a novel deep convolutional encoder-decoder food network with depth-refinement (EDFN-D) using an RGB-D camera for quantifying a plate's remaining food volume relative to reference portions in whole and modified texture foods. We trained and validated the network on the pre-labelled UNIMIB2016 food dataset and tested on our two novel LTC-inspired plate datasets (689 plate images, 36 unique foods). EDFN-D performed comparably to depth-refined graph cut on IOU (0.879 vs. 0.887), with intake errors well below typical 50% (mean percent intake error: [Formula: see text]%). We identify how standard segmentation metrics are insufficient due to visual-volume discordance, and include volume disparity analysis to facilitate system trust. This system provides improved transparency, approximates human assessors with enhanced objectivity, accuracy, and precision while avoiding hefty semi-automatic method time requirements. This may help address short-comings currently limiting utility of automated early malnutrition detection in resource-constrained LTC and hospital settings.

High prevalence of malnutrition and frailty among older adults at admission to residential aged care

INTRODUCTION Malnutrition is an under-recognised and under-treated problem often affecting older adults. AIM The aim of this study was to evaluate the prevalence of and factors associated with malnutrition and frailty among older adults at early admission to residential aged care. METHODS A cross-sectional study was undertaken among eligible older adults within the first week of admission to residential aged care. Participants were assessed for malnutrition risk using the Mini Nutritional Assessment Short Form, frailty using the Fried phenotype criterion, muscle strength using a grip strength dynamometer and gait speed using a 2.4-m walk test. A Cox regression analysis was conducted to identify factors associated with malnutrition risk and frailty status. RESULTS Of 174 participants (mean age 85.5 years, 61% women), two-thirds (66%) were admitted to residential aged care from the community. Most (93%) were either malnourished (48%) or at risk of malnutrition (45%). A total of 76% of participants were frail and 24% were pre-frail. Forty-three percent were both malnourished and frail. Low risk of malnutrition was associated with increases in muscle strength [0.96 (0.93-0.99)], gait speed [0.27 (0.10-0.73)] and pre-frailty status [0.32 (0.12-0.83)]. DISCUSSION This study provides preliminary evidence for high prevalence of malnutrition and frailty at admission to residential aged care. Almost all participants were malnourished or at nutrition risk. Findings highlight the need for strategies to prevent, detect and treat malnutrition in community health care and support nutrition screening at admission to residential aged care.

Cross-Sectional Nutrition Profile of Palliative Home Care Clients in Ontario and Performance of the interRAI Palliative Care Nutrition Clinical Assessment Protocol

BACKGROUND

The nutrition profile of palliative home care clients is unknown. This study describes this group and their nutrition issues and evaluates the performance of the interRAI nutrition Clinical Assessment Protocol (CAP).

METHODS

This was a cross-sectional secondary analysis using Ontario interRAI Palliative Care (interRAI PC) Assessment data. The sample represents 74,963 unique Ontario home care clients assessed between 2011 and 2018. Frequencies and standardized differences (stdiffs) of nutrition characteristics were presented for cancer (n = 62,394) and noncancer (n = 12,569) diagnostic subgroups. Rates of triggering the nutrition CAP were presented by nutrition issue to evaluate its performance.

RESULTS

Of this sample, 16.7% were ≥85 years of age, 52.6% had a prognosis between 6 weeks and 6 months, and 41.4% required assistance with eating. The prevalence was higher among those with nervous/mental/behavioral disorders (72.6%) compared with those with cancer (37.6%; stdiff = 0.75). However, most nutrition issues experienced were similar (stdiff < 0.20) across diagnostic groups. Of the entire sample, 21% triggered the nutrition CAP, indicating a need for further evaluation or intervention. Yet, 73.4% of those who experienced dry mouth, 71.8% of those who required assistance with eating, and 68.4% of those who received a nutrition consult within the last 3 days did not trigger the nutrition CAP.

CONCLUSIONS

Nutrition issues are prevalent in palliative home care clients, regardless of diagnosis; yet the nutrition CAP identified a small fraction of this group. There is a need to focus research and care guidelines toward life-limiting illnesses beyond cancer and address nutrition-related issues in this population.

Diet quality is associated with malnutrition and low calf circumference in Canadian long-term care residents

Background

Older adults living in long-term care (LTC) are nutritionally vulnerable. The purpose of this study was to determine diet quality of Canadian LTC residents and its association with malnutrition and low calf circumference.

Methods

A cross-sectional study was undertaken in 32 LTC homes across four Canadian provinces. Nutrient adequacy ratios (NARs) were calculated for seventeen nutrients; mean adequacy ratio (MAR) was calculated to describe overall diet quality. Malnutrition risk was assessed with the Mini Nutritional Assessment-Short Form (MNA-SF) and diagnosis of protein/energy malnutrition with the Patient-Generated Subjective Global Assessment (PG-SGA). Calf circumference (CC) was also assessed. Linear and logistic regressions for these outcomes with diet quality as the predictor were conducted adjusting for covariates.

Results

Average MNA-SF score was 10.7 ± 2.5. Residents (43.5%) had mild/moderate to severe malnutrition based on the PG-SGA and 32.6% had a CC of < 31 cm. Mean MAR score was 0.79 ± 0.09 with significant differences between those requiring eating assistance (0.77 ± 0.11) and those that did not require assistance (0.80 ± 0.07) (p < .05). MAR score was significantly associated with malnutrition in fully adjusted models: MNA-SF scores [β = 5.34, 95% Confidence interval (CI) (2.81, 7.85)] and PG-SGA [Odds ratio (OR) = 0.49, 95% CI (0.38, 0.64)]. Those who had better diet quality were more likely to be well nourished or not at risk. Although several individual nutrients were associated with low CC (< 31 cm), there was no association between overall diet quality (MAR) and low CC.

Conclusions

Diet quality is associated with malnutrition and individual nutrients (NARs) with a low CC. In addition to calories and protein, nutrient dense diets that promote adequate micronutrient intake are required in LTC.
