Nutritional and Functional Status in Geriatric Day Hospital Patients - MNA Short Form Versus Full MNA

Increased risk of rehospitalisation and death in older hospital patients at risk of malnutrition: A cohort study

OBJECTIVES

The aim of the study was to investigate associations between risk of malnutrition and risk of rehospitalisation and death in older hospital patients, and whether the possible associations were modified by age, gender, comorbidity or Ambulatory Care Sensitive Conditions (ACSCs).

DESIGN

Prospective cohort study.

SETTING

Somatic hospital in Western Norway.

PARTICIPANTS

9,768 hospital admissions for patients aged ≥65 years.

MEASUREMENTS

Information on the risk of malnutrition was based on nutritional risk screening data from 34 point prevalence surveys conducted between 2008 and 2018. Risk of malnutrition was assessed using Nutritional Risk Screening 2002 (NRS 2002) during the initial hospital admission. Outcomes and possible effect modifiers were obtained from the hospital's patient administration systems. The short-term outcome was the length of initial hospital stay. Long-term outcomes included total number of days in hospital, number of hospital stays and risk of death within one year following nutritional risk screening. Statistical analysis involved negative binomial and Cox regression models with adjustment for age, sex and number of diagnoses at time of nutritional risk screening.

RESULTS

Overall, 34% of the patients were classified as being at risk of malnutrition. A higher proportion of the initial admissions were related to ACSCs for patients at risk of malnutrition than for those not at risk. Risk of malnutrition was associated with longer initial hospital stay (adjusted hazard ratio (95% confidence intervals) 1.31 (1.25, 1.37)), more days in hospital (adjusted risk ratio 1.25 (1.18, 1.32)) and a higher risk of having more than two hospital admissions the year following nutritional risk screening (adjusted risk ratio 1.16 (1.07, 1.26)). Patients at risk of malnutrition also had an increased risk of death within one year (adjusted hazard ratio 2.45 (2.25, 2.67)). All associations were more pronounced in the '65-69' and '70-79' age groups compared to the 80+ years age group, and in patients with fewer than four diagnoses compared to patients with four or more diagnoses. No significant interaction was detected between sex and risk of malnutrition with regard to patient outcomes.

CONCLUSION

Older patients at risk of malnutrition have a higher risk of rehospitalisation and death during the first year after nutritional risk screening compared with those not at risk. Among patients at risk of malnutrition, the initial hospital admissions were more often due to ACSCs. The impact of the risk of malnutrition on outcomes appears stronger in patients aged 65-79 years and in patients with less comorbidity. These findings underline the importance of nutritional risk screening and subsequent nutritional support in all groups of older patients.

Malnutrition defined by global leadership initiative on malnutrition criteria impedes home discharge in acute care hospital admissions

BACKGROUND & AIMS

Limited evidence exists on the association between malnutrition diagnosis using the Global Leadership Initiative on Malnutrition (GLIM) criteria in hospitalized acute care patients and their outcomes; several aspects still require clarification. This study aimed to evaluate the relationship between malnutrition, as defined by the GLIM criteria, at the time of acute hospital admission and discharge to home.

METHODS

This retrospective observational study was conducted at a hospital that provides acute care in Japan. Adult patients admitted between July 2023 and April 2024 were included in this study. The primary outcome was the number of patients discharged to home, with in-hospital mortality as the secondary outcome. To ensure the reliability of the cohort-wide results, background factors were adjusted using propensity score matching. The two groups were compared based on the presence or absence of malnutrition, as defined by the GLIM criteria at admission. Furthermore, multiple logistic regression analysis was conducted, with the outcome as the dependent variable and malnutrition, diagnosed using the GLIM criteria, as the explanatory variable, adjusting for covariates.

RESULTS

A total of 1007 patients were included in the final analysis, of whom 492 (49 %) were diagnosed without malnutrition, while 515 (51 %) were diagnosed with malnutrition according to the GLIM criteria. In the multivariate logistic regression analysis after matching, malnutrition defined by the GLIM criteria emerged as an independent factor associated with discharge to home (odds ratio [OR] = 0.37, 95 % confidence interval = 0.25-0.56, P < 0.001) when adjusting for age, sex, and various comorbidities. Among the GLIM sub-criteria, reduced muscle mass, reduced food intake or assimilation, and disease burden or inflammation were independently associated with discharge to home. Notably, disease burden/inflammation exhibited the lowest OR among the GLIM sub-criteria for discharge.

CONCLUSION

Malnutrition diagnosed using the GLIM criteria upon admission in patients admitted to a regional hospital providing acute care was associated with decreased rates of discharge to home and increased in-hospital mortality. Specifically, attention should be paid to the criteria for reduced muscle mass and disease burden or inflammation within the GLIM framework.

Factors Influencing Nutritional Status in Hospitalized Individuals Aged 70 and Above

BACKGROUND

Older adults are vulnerable to malnutrition due to physical, psychological, and social factors. Malnutrition, a prevalent and modifiable issue in this population, is associated with an elevated risk of adverse clinical outcomes. The purpose of the study is to assess the nutritional status of older adult individuals admitted to a general hospital and examine its correlation with socio-health and demographic variables.

METHODS

The study included 239 individuals aged 70 and above, employing a cross-sectional descriptive observational approach with a convenience sampling method. Sociodemographic information was gathered, and variables such as cognitive impairment, functional capacity, comorbidities, medication consumption, and nutritional status were evaluated. Statistical analysis involved descriptive calculations, bivariate analysis, and multivariate analysis, utilizing binary logistic regression.

RESULTS

Approximately half of the sample were at risk of malnutrition, with a more notable prevalence among women. Factors such as age (OR = 1.04), cognitive impairment (OR = 1.06), functional dependence (OR = 0.96), and comorbidities (OR = 1.08) were linked to an elevated risk of malnutrition. In our regression model, age, cognitive impairment, and drug consumption emerged as significant predictors of malnutrition risk.

CONCLUSIONS

Individuals aged 70 and above have a notably high prevalence of malnutrition risk, particularly among those experiencing functional dependence and cognitive impairment. In our sample, cognitive impairment in older adults, coupled with above-median drug consumption, emerges as the primary predictor for malnutrition risk.

Development and Validation of a Risk Prediction Model for Frailty in Patients with Chronic Diseases

The occurrence rate of frailty is high among patients with chronic diseases. However, the assessment of frailty among these patients is still far from being a routine part of clinical practice. The aim of this study is to develop a validated predictive model for assessing frailty risk in patients with chronic illnesses. This study recruited 543 patients with chronic diseases, and 237 were included in the development and validation of the predictive model. A total of 57 frailty related indicators were analyzed, encompassing sociodemographic variables, health status, physical measurements, nutritional assessment, physical activity levels, and blood biomarkers. There were 100 cases (42.2%) presenting frailty symptoms. Multivariate logistic regression analysis revealed that gender, age, chronic diseases, Mini Nutritional Assessment score, and Clinical Frailty Scale score were predictive factors for frailty in chronic disease patients. Utilizing these factors, a nomogram model demonstrated good consistency and accuracy. The AUC values for the predictive model and validation set were 0.946 and 0.945, respectively. Calibration curves, ROC, and DCA indicated the nomogram had favorable predictive performance. Altogether, the comprehensive nomogram developed here is a promising and convenient tool for assessing frailty risk in patients with chronic diseases, aiding clinical practitioners in screening high-risk populations.

Mini nutritional assessment-short form test: criterion and predictive validity in older adults from a long-term care unity

Introduction

Introduction: the Mini Nutritional Assessment Short-Form test (MNA-SF) is valid for malnutrition screening and diagnosis of older adults, but few studies evaluated if it predicts hospital length of stay (LOS) and were conducted in long-term care units. Objective: this study aims to evaluate the criterion and predictive validity of MNA-SF. Methods: a prospective observational study was conducted in older adults from a long-term care unity. MNA Long Form test (MNA-LF) and MNA-SF were applied, at admission and at discharge. Percentage of agreement, kappa and intra-class correlation coefficients (ICC) were determined. Sensitivity and specificity of MNA-SF were calculated. The independent association of MNA-SF with LOS (adjustment for Charlson index, sex, age, education) was assessed by Cox regression analysis [results presented as hazard ratio (HR) and 95 % confidence intervals (CI)]. Results: this sample is composed of 109 older adults (62.4 % women), aged 66-102 years. According to MNA-SF at admission, 7.3 % of participants presented normal nutrition status, 55.1 % were at risk of malnutrition and 37.6 % were malnourished. Agreement, kappa and ICC were 83.5 %, 0.692 and 0.768 at admission, and 80.9 %, 0.649 and 0.752 at discharge. MNA-SF sensitivities were 96.7 % at admission and 92.9 % at discharge; specificities were 88.9 % and 89.5 %, at admission and at discharge. According to MNA-SF at discharge, being at risk of malnutrition (HR = 0.170, 95 % CI: 0.055-0.528) or malnourished (HR = 0.059, 95 % CI: 0.016-0.223) lowered the odds of being discharged to home or to usual residence. Conclusions: a high agreement was found between MNA-LF and MNA-SF. MNA-SF revealed high sensitivities and specificities. An independent association was found between risk of malnutrition or malnutrition by MNA-SF and LOS. The use of MNA-SF instead of MNA-LF should be considered in long-term care units given its criterion and predictive validity.

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.

[Nutritional status and use of health resources following the implementation of a PEG tube nutrition program for neurological patients in home hospitalization]

Objective: the objective of this study was to demonstrate that implementation of enteral nutrition by gastrostomy tube by the Home Hospitalization Unit (HHU) in patients suffering from neurological diseases, significantly improves their nutritional status, both in terms of anthropometric and analytical parameters. Methods: data on admissions, days of hospital stay, emergency room visits and nutritional parameters were collected during the 6 months before and 6 months after placement of a percutaneous endoscopic gastrostomy (PEG) tube in 100 patients from the UHD at General University Hospital in Elda (Alicante). Results: a total of 100 neurological patients were included in the study; 58 % of them were women and with a mean age (standard deviation, SD) of 78.3 (13.3) years, with 60 % of the patients being > 80 years. The monitoring and home treatment of these patients by the HHU of General University Hospital in Elda led to improvement in quality of life and nutritional parameters (weight, body mass index, proteins, albumin, prealbumin, creatinine, and hemoglobin), as well as a decrease in the number of complications derived from the nutritional management of patients at their home, and a significant reduction in number of admissions (90.27 %) and days of hospital stay (94.05 %), as well as of visits to emergency services (79.47 %), with a consequent reduction in healthcare costs. Conclusions: the implementation of a home-based monitoring program for patients with PEG by a HHU improves their nutritional status and reduces healthcare costs.

The Influence of Exercise, Nutritional Status, and Disease on the Functional Ability to Undertake Activities of Daily Living and Instrumental Activities of Daily Living in Old Taiwanese People

This study aimed to examine the influence of changes in exercise status, nutritional status, and a number of comorbidities on functional ability in Taiwanese community-dwelling older adults. Data were obtained from the Taiwan Longitudinal Study of Aging. The results revealed that current exercise and consistent exercise were negatively associated with subsequent 4- and 8-year activities of daily living (ADL) and instrumental ADL (IADL) decline (all p < 0.05). The Mini-Nutritional Assessment (MNA) score was negatively associated with subsequent 8-year IADL decline (all p < 0.05), while the number of diseases was positively associated with subsequent 4- and 8-year IADL decline (all p < 0.05). Current exercise and consistent exercises are beneficial for adults aged ≥ 65 years to maintain their functional ability in ADL and IADL and to prevent declines in functional ability. Consistency of exercise, MNA score, and the number of chronic diseases are good predictors of IADL decline.

An extended version of the MNA-SF increases sensitivity in identifying malnutrition among community living older adults. Results from the PRONUTRISENIOR project

BACKGROUND & AIMS

The Mini Nutritional Assessment (MNA) is the most used tool to assess malnutrition and/or its risk among older adults. Its Screening section was proposed as a short form (MNA-SF) but studies comparing the two forms present controversial results. Our main aims were to study the agreement between MNA-SF and its full form (MNA-FF) among Portuguese older adults living in the community and to develop a more sensible version of the MNA-SF.

MATERIAL AND METHODS

This cross-sectional study used a convenience sample of 456 older adults (54.2% females) aged 65-92 years (mean = 73; SD = 6). Data analyzed included: nutritional status (MNA), social support (Fillenbaum's Social Network Index), level of independency in daily activities (Lawton e Brody's scale) and eating-related quality of life. Both MNA-FF and MNA-SF classify participants as malnourished, at risk of malnutrition or with normal nutrition status. Anthropometric assessments (weight, height, arm and calf perimeters) were carried out and BMI was computed.

RESULTS

The agreement between the two classifications is 82.7%, but Cohen's k shows a weak agreement (weighted Cohen's k = 0.497; p < 0,001), and the sensitivity of the MNA-SF to detect malnutrition or its risk (as assessed by the MNA-FF) was 42.6% (despite a specificity of 98.8%). Participants classified as normal using the MNA-SF despite at risk using the MNA-FF present lower scores in two items from the Assessment section (number of full meals eaten daily and amount of fluid consumed per day). These were included in MNA-SF to obtain an extended short-version (MNA-SF8). The difference between the ROC curves for MNA-SF and MNA-SF8 justifies the preferential use of the MNA-SF8 with an estimated cut-off of 14 points, which showed high sensitivity (91.8%) and specificity (79.9%).

CONCLUSIONS

The addition of two items to the MNA-SF provides a more sensible tool to detect the risk of malnutrition among older adults. General eating-related questions seem relevant to assess malnutrition in this age group.

Nutritional status and physical performance using handgrip and SPPB tests in hospitalized older adults

BACKGROUND & AIMS

Malnutrition and poor physical performance are highly prevalent within hospitalized older adults, and both have in common the loss of muscle mass. Likewise, there is growing interest in identifying markers of physical performance, other than just measuring muscle mass, that might be useful for managing malnutrition. This study aimed to (i) characterize the physical condition of hospitalized older adults in comparison to previously published reference percentile values of same age adults and (ii) to examine the association between the nutritional status and physical performance of older inpatients.

METHODS

A total of 604 inpatients (age 84.3 ± 6.8 years, 50.3% women) participated in this cross-sectional study. Patients were assessed for nutritional status (Mini Nutritional Assessment-Short Form (MNA-SF)) and physical performance (handgrip strength and the Short Physical Performance Battery (SPPB)).

RESULTS

During hospitalization, 65.7% of the inpatients were at risk of malnutrition or malnourished. More than a half of the older inpatients were unfit (≤P25) for handgrip strength (52.0%) and SPPB total score (86.3%) as well as for two of its subtests, gait speed (86.7%) and 5 times sit-to-stand (91.1%) tests. Patients' nutritional status was significantly associated with better physical performance within all tests (all p < 0.001), as their nutritional status improved so did their physical performance (all p for trend <0.001). Hence, being at risk of malnutrition or malnourished significantly increased the likelihood for being classified as unfit according to handgrip strength (OR: 1.466, 95% CI: 1.045-2.056), SPPB total score (OR: 2.553, 95% CI: 1.592-4.094) and 4-m walking test (OR: 4.049, 95% CI: 2.469-6.640) (all p < 0.05), and as frail (OR: 4.675, 95% CI: 2.812-7.772) according to the SPPB frailty threshold (p < 0.001).

CONCLUSIONS

This study reinforces the use of handgrip strength and SPPB, as well as its subtests (gait speed and 5 times sit-to-stand tests), in hospitalized older adults as alternative measures of muscle mass for malnutrition management. Hence, it seems that risk of malnutrition or malnutrition assessed by MNA-SF might help to predict poor physical performance in older inpatients.

Malnutrition and depression as predictors for 30-day unplanned readmission in older patient: a prospective cohort study to develop 7-point scoring system

BACKGROUND

Readmission is related to high cost, high burden, and high risk for mortality in geriatric patients. A scoring system can be developed to predict the readmission of older inpatients to perform earlier interventions and prevent readmission.

METHODS

We followed prospectively inpatients aged 60 years and older for 30 days, with initial comprehensive geriatric assessment (CGA) on admission in a tertiary referral centre. Patients were assessed with CGA tools consisting of FRAIL scale (fatigue, resistance, ambulation, illness, loss of weight), the 15-item Geriatric Depression Scale, Mini Nutritional Assessment short-form (MNA-SF), the Barthel index for activities of daily living (ADL), Charlson Comorbidity Index (CCI), caregiver burden based on 4-item Zarit Burden Index (ZBI), and cognitive problem with Abbreviated Mental Test (AMT). Demographic data, malignancy diagnosis, and number of drugs were also recorded. We excluded data of deceased patients and patients transferred to other hospitals. We conducted stepwise multivariate regression analysis to develop the scoring system.

RESULTS

Thirty-day unplanned readmission rate was 37.6 %. Among 266 patients, 64.7 % of them were malnourished, and 46.5 % of them were readmitted. About 24 % were at risk for depression or having depressed mood, and 53.1 % of them were readmitted. In multivariate analysis, nutritional status (OR 2.152, 95 %CI 1.151-4.024), depression status (OR 1.884, 95 %CI 1.071-3.314), malignancy (OR 1.863 95 %CI 1.005-3.451), and functional status (OR 1.584, 95 %CI 0.885-2.835) were included in derivation of 7 score system. The scoring system had maximum score of 7 and incorporated malnutrition (2 points), depression (2 points), malignancy (2 points), and dependent functional status (1 point). A score of 3 or higher suggested 82 % probability of readmission within 30 days following discharge. Area under the curve (AUC) was 0.694 (p = 0.001).

CONCLUSIONS

Malnutrition, depression, malignancy and functional problem are predictors for 30-day readmission. A practical CGA-based 7 scoring system had moderate accuracy and strong calibration in predicting 30-day unplanned readmission for older patients.

Association between kidney function, nutritional status and anthropometric measures in older people : The Screening for CKD among Older People across Europe (SCOPE) study

BACKGROUND

Different mechanisms connect the nutritional status with the occurrence and the course of chronic kidney disease (CKD). The end-stage renal disease is complicated by catabolic inflammatory reactions and cachexia which leads to malnutrition (undernutrition). On the other hand, obesity is an important risk factor for the development and acceleration of CKD.

METHODS

In the SCOPE study, community-dwelling persons aged 75 years and over, from 6 European countries and Israel were examined at the baseline phase. We assessed the relationship between anthropometric measures (Body Mass Index (BMI), circumferences of arm (AC), waist (WC), hip (HC), and calf (CC), waist-to-hip ratio - WHR, waist-to-height ratio - WHtR, risk of malnutrition (Mini Nutritional Assessment - MNA), serum albumin) and estimated glomerular filtration rate (eGFR) calculated by Berlin Initiative Study (BIS) equation.

RESULTS

We studied 2151 subjects (932 men and 1219 women) with a mean age of 79.5 ± 5.9 years. A total of 1333 (62%) participants had CKD (GRF < 60 ml/min/1.73 m²). Negative correlations between eGFR and weight, AC, WC, HC, CC, BMI, WHtR were observed. Positive correlation occurred between eGFR and MNA score (Spearman's rho = 0.11) and albumin concentration (rho = 0.09). Higher weight, AC, WC, HC, CC, BMI and WHtR increased the odds ratio of CKD; higher MNA (OR = 0.98, 95% CI 0.94-1.0) and higher serum albumin (OR = 0.73, 95% CI 0.53-1.0) were weakly associated with reduced odds. The risk of malnutrition was the highest with eGFR < 30 as compared to eGFR > 60 (OR = 2.95, 95%CI = 1.77-4.94 for MNA < 24; OR = 5.54, 95%CI = 1.66-18.5 for hypoalbuminemia < 3.5 g/dL).

CONCLUSION

The population of community dwelling people aged 75+ with CKD shows general features of overweight and obesity with a small prevalence of malnutrition. For anthropometric measures, the strongest association with eGFR and the highest odds of CKD were identified using WC, HC, CC and WHtR. Albumin level and MNA, but not MNA Short Form, indicated an increased odds of malnutrition with a decrease in eGFR.

Is mini-nutritional assessment a reliable tool in detecting malnutrition in elderly with body weight excess?

PURPOSE

The rising proportion of elderly population in high-income societies has resulted in increasing number of subjects with chronic disabling diseases and nutritional deficiency. Elderly's nutritional status is usually assessed through the mini-nutritional assessment (MNA^®). However, its effectiveness may be influenced by weight excess or obesity. We tested the performance of MNA^® questionnaire in subjects aged ≥ 65 years from Northern Sardinia, Italy, according to overweight/obesity, and we tried to identify the factors associated with malnutrition.

METHODS

A modified version of MNA^® (mMNA) test, not including BMI, was compared with the conventional MNA^® (cMNA) test, and the overall test performance was assessed by calculating sensitivity, specificity and accuracy. In addition, indexes of cognitive health, disability, comorbidity and polypharmacy were compared between patients with concordant and discordant MNA tests.

RESULTS

cMNA^® sensitivity, specificity and accuracy were 67%, 99% and 84% compared with the mMNA test, due to malnourished patients misclassified as normal because of excess weight. Predictors of malnutrition were: depression (p < 0.0001), disability (p < 0.0001) and polypharmacy (p < 0.0001). Interestingly, the average scores of the "global", "subjective" and "dietary" components of the cMNA^®, were significantly lower compared with the corresponding scores of the mMNA.

CONCLUSIONS

Excess of weight, a condition progressively rising in the elderly population, may reduce the performance of cMNA^® test in detecting malnutrition.

Nutritional Status Is Associated with Function, Physical Performance and Falls in Older Adults Admitted to Geriatric Rehabilitation: A Retrospective Cohort Study

Nutritional status is relevant to functional recovery in patients after an acute process requiring rehabilitation. Nevertheless, little is known about the impact of malnutrition on geriatric rehabilitation. This study aimed to determine the association between nutritional status at admission and the evolution of functional and physical outcomes, as well as the capability of nutritional status to identify fallers among patients admitted to geriatric rehabilitation for different reasons. This was a retrospective cohort study of 375 patients. Data collected included age, gender, diagnosis at admission, comorbidities, cognitive and nutritional status, functional and physical measurements, length of stay, mortality and falls. Orthogeriatric patients with worse nutritional status according to the Mini Nutritional Assessment-Short Form (MNA-SF) had a significantly lower Barthel Index at admission and discharge with worse functional gain and poorer outcomes in the Short Physical Performance Battery (SPPB). However, in hospital-deconditioned patients, the MNA-SF score was not significantly associated with functional and physical recovery. Poor nutritional status at admission increased the risk of experiencing at least one fall during rehabilitation in orthogeriatric patients. However, hospital-deconditioned patients who fell had better SPPB scores than those who did not fall. Our results demonstrate the importance of nutritional status in the clinical evolution of orthogeriatric patients throughout the rehabilitation process.

Nutritional Status Plays More Important Role in Determining Functional State in Older People Living in the Community than in Nursing Home Residents

The aim of this study was to verify whether the relationship between nutritional and functional status differs between seniors in the community and those in long-term care institutions. One hundred nursing home (NH) residents aged 60 years and above and 100 sex- and age-matched community-dwelling (CD) older adults were examined. Functional status was assessed using the Comprehensive Geriatric Assessment (CGA) and nutritional status using anthropometric measures, the Mini Nutritional Assessment questionnaire (MNA) and bioimpedance analysis (BIA). Significant environmental interactions were observed with resting metabolic rate (RMR), extracellular water (ECW) and intracellular water (ICW) ratio, skeletal muscle mass (SMM), skeletal muscle index (SMI) and impedance (Z) and resistance (R) to the results of the Timed Up and Go (TUG) test. The two groups demonstrated different relationships between Z and R and handgrip strength and between Geriatric Depression Scale (GDS) score and fat free mass (FFM), body density, total body water (TBW) and phase angle (PhA). Nutritional status seems to be more important for functional state in CD older people than in NH residents. Therefore, to ensure the functional independence of seniors living in the community, it is crucial to maintain the correct nutritional parameters. Further studies are necessary to account for the fact that this relationship is less significant among NH residents and to identify other factors that may contribute to these discrepancies between community and institutional environments.

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.

Monitoring Immobilized Elderly Patients Using a Public Provider Online System for Pressure Ulcer Information and Registration (SIRUPP): Protocol for a Health Care Impact Study

BACKGROUND

Pressure ulcers represent a major challenge to patient safety in the health care context, presenting high incidence (from 7% to 14% in Spain) and increased financial costs (€400-600 million/year) in medical treatment. Moreover, they are a significant predictor of mortality. The prevention of pressure ulcers in long-term care centers and patients' own homes is proposed as a priority indicator of health care quality. Early stage risk assessment and database recording are both crucial aspects of prevention, classification, diagnosis, and treatment.

OBJECTIVE

This project proposes a 3-year study of immobilized patients residing in the Granada-Metropolitan Primary Healthcare District (DSGM) and monitored via the Pressure Ulcer Information and Registration System (SIRUPP, Spanish initials). The project aims to estimate the incidence of PUs among immobilized elderly patients, analyze the health-related quality of life of these patients by using the Pressure Ulcer Quality of Life (PU-QoL) instrument in a sample of 250 patients, determine the average time to complete wound healing, estimate the rate of pressure ulcers-associated mortality, and assess the predictive value of the Braden and Mini Nutritional Assessment risk measurement scales in a sample of 1700 patients.

METHODS

The DSGM runs SIRUPP, which is linked to patients' electronic health records. Currently, 17,104 immobilized patients are monitored under this system. Health-related quality of life will be measured by patient self-reports using the Spanish Pressure Ulcer Quality of Life questionnaire, following cross-cultural adaptation and psychometric validation with respect to the English-language version.

RESULTS

The project commenced in June 2017 and is expected to conclude in April 2020.

CONCLUSIONS

This study addresses two main health outcomes-the time needed for wound healing and the mortality associated with pressure ulcers-both of which might be accounted for by variations in clinical practice and the health-related quality of life of patients with pressure ulcers.

Factors related to home discharge in malnourished community-dwelling older adults: A retrospective longitudinal cohort study

Patients who become malnourished during hospitalization because of illness or treatment often receive intervention from a nutrition support team (NST). The NST intervention not only enhances the nutritional status but also decreases medical expenses and catheter-related complications. However, the impact of the NST intervention on the home discharge of hospitalized community-dwelling older adults remains unclear. Hence, this study aims to investigate factors related to home discharge in malnourished community-dwelling older adults.In this retrospective longitudinal cohort study, examined 191 community-dwelling older adults aged ≥65 years (108 males; mean age: 80.9 ± 7.8 years) who received the NST intervention. All participants were categorized into two groups based on whether they were home discharged or not (home discharge group and non-home discharge group). We performed intergroup comparisons using serum albumin (Alb) as an index of the nutritional status and functional independence measure (FIM: motor and cognitive items) as an index of activities of daily living (ADL). Furthermore, we constructed a prognostic model of home discharge using the logistic regression analysis.The home discharge group had 94 participants, with a home discharge rate of 50.8%. Baseline body mass index (BMI), motor-FIM score, and cognitive-FIM score were significantly higher in the home discharge group compared with the non-home discharge group (P = .002, P < .001, P < .001, respectively). In the home discharge group, BMI declined significantly, Alb elevated significantly, and both motor-FIM and cognitive-FIM score enhanced significantly by the completion of the NST intervention (P < .001, P < .001, P < .001, P = .005, respectively). The adjusted logistic regression analysis extracted the baseline BMI (odds ratio [OR], 1.146; 95% confidence interval [CI]: 1.034-1.270), baseline motor-FIM score (OR, 1.070; 95% CI: 1.036-1.105), and extent of change in the motor-FIM score (OR, 1.061; 95% CI: 1.026-1.098) as independent factors that predict home discharge.This study highlights the significance of higher baseline BMI, higher baseline ADL level, ADL enhancements, and improvements in the nutritional status by the NST intervention in malnourished community-dwelling older adults considering home discharge.

Predictability of a modified Mini- Nutritional- Assessment version on six-month and one-year mortality in hospitalized geriatric patients: a comparative analysis

Recently we introduced a modified Mini Nutritional Assessment (MNA) Short Form (MNA-SF) and Long Form (MNA-SF) with operationalization of the ‘mobility’ and ‘neuropsychological problems’ items of the MNA using scores on Barthel Index mobility item and Mini Mental State Examination and Geriatric Depression Scale scores. We have now evaluated the abilities of this modified MNA-SF and MNA-LF to predict mortality in comparison with the standard MNA-SF and MNA-LF and the Nutritional Risk Screening 2002 (NRS 2002) and the Malnutrition Universal Screening Tool (MUST). A prospective analysis was performed in 240 hospitalised geriatric patients aged ≥ 65 years. Malnutrition and/or malnutrition risk were assessed using the modified MNA-SF and MNA-LF, the standard MNA-SF and MNA-LF, and the NRS 2002 and MUST. The modified MNA-SF and MNA-LF and the standard MNA-SF and MNA-LF assessments (all p < 0.05), but not NRS 2002 or MUST (all p ≥ 0.05), predicted six-month and/or one-year mortality. Prediction of six-month and/or one-year mortality by the modified MNA-SF was comparable with predictions by the standard MNA-SF and MNA-LF (all p ≥ 0.05). The modified MNA-LF showed better prediction of six-month and one-year mortality than the standard MNA-SF and MNA-LF (all p < 0.05). The modified MNA-LF (all adjusted p < 0.05), but none of the other instruments (all adjusted p ≥ 0.05), predicted six-month and one-year mortality independently of age, sex, frailty, comorbidity and ADL disability burden. The modified MNA-SF and MNA-LF emerged as potentially valuable tools for predicting mortality in patients hospitalised on geriatric wards.

The relationship between physical activity and appetite in patients with heart failure: A prospective observational study

INTRODUCTION

Physical activity and appetite are important components for maintaining health. Yet, the association between physical activity and appetite in heart failure (HF) populations is not completely understood. The aim of the present study was to investigate the relationship between physical activity, functional capacity, and appetite in patients with HF.

METHODS

This was a prospective observational study. In total, 186 patients diagnosed with HF, New York Heart Association (NYHA) class II-IV (mean age 70.7, 30% female), were included. Physical activity was measured using a multi-sensor actigraph for seven days and with a self-reported numeric rating scale. Physical capacity was measured by the six-minute walk test. Appetite was measured using the Council on Nutrition Appetite Questionnaire. Data were collected at inclusion and after 18 months. A series of linear regression analyses, adjusted for age, NYHA class, and B-type natriuretic peptide were conducted.

RESULTS

At baseline, higher levels of physical activity and functional capacity were significantly associated with a higher level of appetite in the unadjusted models. In the adjusted models, number of steps ( p = 0.019) and the six-minute walk test ( p = 0.007) remained significant. At the 18-month follow-up, all physical activity variables and functional capacity were significantly associated with appetite in the unadjusted regression models. In the adjusted models, number of steps ( p = 0.001) and metabolic equivalent daily averages ( p = 0.040) remained significant.

CONCLUSION

A higher level of physical activity measured by number of steps/day was associated with better self-reported appetite, both at baseline and the 18-month follow-up. Further research is needed to establish causality and explore the intertwined relationship between activity and appetite in patients with HF.

Malnutrition Screening and Assessment in Hospitalised Older People: a Review

Malnutrition (undernutrition) remains one of the most serious health problems for older people worldwide. Many factors contribute to malnutrition in older people, including: loss of appetite, polypharmacy, dementia, frailty, poor dentition, swallowing difficulties, social isolation, and poverty. Malnutrition is common in the hospital setting, yet often remains undetected by medical staff. The objective of this review is to compare the validity and reliability of Nutritional Screening Tools (NSTs) for older adults in the hospital setting. We also provide an overview of the various nutritional screening and assessment tools used to identify malnutrition in hospitalised older adults. These include: Subjective Global Assessment (SGA), the Mini Nutritional Assessment (MNA), MNA-short form (MNA-SF), Malnutrition Universal Screening Tool (MUST), Simplified Nutritional Appetite Questionnaire (SNAQ), Geriatric Nutrition Risk Index (GNRI) and anthropometric measurements. The prevalence and outcomes of malnutrition in hospitalised older adults are also addressed.

Prevalence of malnutrition using harmonized definitions in older adults from different settings - A MaNuEL study

BACKGROUND & AIMS

Malnutrition is widespread among older people and related to poor outcome. Reported prevalences vary widely, also because of different diagnostic criteria used. This study aimed to describe prevalences in several populations of older persons in different settings using harmonized definitions.

METHODS

Available studies within the Joint Programming Initiative (JPI) Knowledge Hub 'Malnutrition in the Elderly' (MaNuEL) were used to calculate and compare prevalences of malnutrition indicators: low BMI (<20 kg/m²; age-specific BMI <20 if age 65-<70 and <22 kg/m² if age ≥70 years), previous weight loss (WL), moderate and severe decrease in food intake, and combined BMI <20 kg/m² and/or WL in participants aged ≥65 years.

RESULTS

Fifteen samples with in total 5956 participants (59.3% women) were included: 7 consisting of community-dwelling persons, 2 studies in geriatric day hospitals, 3 studies in hospitalized patients and 3 in nursing homes. Mean age of participants ranged between 67 and 87 years. Up to 4.2% of community-dwelling persons had a BMI <20 kg/m², 1.6 and 9% of geriatric day hospital patients, 4.5-9.4% of hospital patients and 3.8-18.2% of nursing home residents. Using age-specific cut-offs doubled these prevalences. WL was reported in 2.3-10.5% of community-dwelling persons, 6% and 12.6% of geriatric day hospital patients, 5-14% of hospitalized patients and 4.5-7.7% of nursing home residents. Severe decrease in food intake was recorded in up to 9.6% of community-dwelling persons, 1.5% and 12% of geriatric day hospital patients, 3.4-34.2% of hospitalized patients and 1.5-8.2% of nursing home residents. The criteria age-specific BMI and WL showed opposing prevalences across all settings. Compared to women, low BMI and moderate decrease in food intake showed low prevalences in men but similar prevalences were observed for weight loss and severe decrease in food intake. In half of the study samples, participants in a younger age group had a higher prevalence of WL compared to those of an older age group. Prevalence of BMI <20 kg/m² and WL at the same time did not exceed 2.6% in all samples. The highest prevalences were observed based on combined definitions when only one of the three criteria had to be present.

CONCLUSIONS

Prevalences for different criteria vary between and within the settings which might be explained by varying functional status. The criteria used strongly affect prevalence and it may be preferable to look at each criterion separately as each may indicate a nutritional problem.

Malnutrition and Malnutrition Risk Can Be Associated with Systolic Orthostatic Hypotension in Older Adults

BACKGROUND

Malnutrition and orthostatic hypotension(OH) are the two important geriatric syndromes, which have similar negative outcomes such as falls. The aim of the study is to detect whether there is any relation between malnutrition and OH.

METHODS

862 geriatric patients, who had undergone comprehensive geriatric assessment (CGA),were included in the retrospective study. OH was identified as 20 and/or 10 mmHg dropped for systolic and/or diastolic blood pressures with the active standing test when patients got up from supine to standing position. Nutritional status was checked according to Mini Nutritional Assesment-Short Form(MNA-SF).

RESULTS

The mean age of the patients was 74±8.05, and %66.3 of them were female. The prevalence of malnutrition, malnutrition-risk and OH were detected as 7.7%, 26.9 % and 21.2%, respectively. When OH, systolic OH, diastolic OH and control group were compared with CGA parameters and the effects of age and gender were removed, the frequency of falls and Timed-Up and Go Test were higher, activity daily living indexes and TINETTI-Balance scores were lower in systolic OH than without it (p<0.05).Systolic OH was more frequent in malnutrition-risk and malnutrition group than control group (p<0.002 and p<0.05, respectively). Diastolic OH was not associated with nutritional status (p>0.05).OH was only higher in malnutrition-risk group than robust (p<0.05).

CONCLUSION

Our findings suggest that not only malnutrition but also malnutrition-risk may be associated with systolic OH, which leads to many negative outcomes in older adults. Because malnutrition/ malnutrition risk is preventable and reversible, nutritional status should be checked during the evaluation of OH patients.

Validity of the Self- Mini Nutritional Assessment (Self- MNA) for the Evaluation of Nutritional Risk. A Cross- Sectional Study Conducted in General Practice

INTRODUCTION

Malnutrition is a frequent condition in the elderly especially in hospitals and in nursing homes, and even among the free-living elders the prevalence is not negligible (5-10%). Awareness towards malnutrition is still limited. The lack of time for nutritional assessment by the overcommitted healthcare personnel, including the general practitioners (GPs), may represent one possible explanation for limited recognition of malnutrition. Therefore, a self-administered instrument could be useful in raising alert on the GPs and allow early detection of malnutrition and early care provision. The aim of the present study was to analyze the validity of the Self-MNA that takes cue from the Mini Nutritional Assessment- Short Form (MNA-SF) and has been adapted to be self-administered by free-living elderly subjects.

METHODS

Participants were recruited from patients referring to the GP offices in Italy. Nutritional evaluation was performed through the administration of Full-MNA, MNA-SF and Self-MNA. The comorbidity level was assessed through the Cumulative Illness Rating Scale (CIRS). The level of difficulty in filling out the test was reported by the participants, and the time spent to complete the Self-MNA was also registered.

RESULTS

A total of 226 subjects, 125 women and 101 men (75.1 ±8 and 75.3 ± 8 years old, respectively; p=0.89) were enrolled, and 214 (94.7%) of them completed the Self-MNA. According with the Full-MNA test score, 8.4% of women and 3.5% of men were classified as malnourished, whereas 32.7% of women and 31.4% of men were at risk of malnutrition. Agreement between Self-MNA and Full-MNA, and Self-MNA vs. MNA-SF was classified as "moderate" (k = 0.476 and 0.496 respectively; p < 0.001). Self-MNA showed a fair predictive value compared to the Full-MNA and MNA-SF tests (76.6 and 79.9%, respectively) with a barely adequate sensitivity (70.9 and 75.4%, respectively). The analysis of the characteristics of FN (false negative: subjects who were considered at risk of malnutrition or malnourished at Full-MNA but not at Self-MNA) showed that the clinical and functional aspects of these subjects (age, comorbidity and severity, time necessary to complete the Self-MNA, decrease in food intake, severe illness in the past 3 months, dementia and depression, fluid intake, need for feeding assistance, arm and calf circumferences) were very similar to the characteristics of true positive subjects. Patients required 6.7 ± 4.5 minutes to complete the test and 25 subjects (11.7%) needed more than 10 minutes, up to a maximum of 30 minutes. Patients who stated a greater difficulty were older (79.8 ± 7 vs. 73.5 ± 7 years; p<0.001), they were more «malnourished» at Full-MNA (10.7 vs. 1,7%; p= 0.006) and clinical status was characterized by a higher severity index (1.72 ± 0.6 vs. 1.41 ± 0.4; p= 0.008).

CONCLUSION

In the present study we investigated the validity of the Self-MNA in a sample of free-living elderly subjects. The results obtained confirm the validity of the test that may represent a useful tool for the GPs, although some important limitations need to be considered, limiting its use in clinical practice.

Mini Nutritional Assessment Short-Form (MNA-SF) Predicts Institutionalisation in an Intermediate Post-Acute Care Setting

OBJECTIVES

The aim of the study was to investigate whether nutritional status as measured by the Mini Nutritional Assessment Short-Form (MNA-SF) predicts level of care of the discharge destination after post-acute care in a nursing home.

DESIGN

Cohort study.

SETTING

Post-acute intermediate care nursing home, 19-bed unit with increased multidisciplinary staff.

PARTICIPANTS

Patients ≥70 years in post-acute care (N=900) following an acute admission to the hospital.

MEASUREMENTS

The predictive value of nutritional status, as measured by the MNA-SF, on discharge destination was analysed by means of a multinomial logistic regression model with the MNA-SF as the independent variable, discharge destination as the dependent variable and age and living situation as co-variates. The participants were grouped into three categories according to their discharge destination: home, other institution or readmitted to the hospital.

RESULTS

A higher score on the MNA-SF significantly predicted a reduced risk of discharge to institution (adjusted OR=0.90 (95% CI=0.84;0.97), p=0.003).

CONCLUSION

Nutritional status, as measured by the MNA-SF, predicted discharge destination from an intermediate care nursing home following acute hospitalisation. The findings underscore the value of nutritional assessment as part of overall clinical assessment and care planning prior to discharge. The findings may also imply that interventions to improve nutritional status could increase patients' ability to return home, as opposed to further institutionalisation, after hospitalisation.

Mortality Risk Factors Among Patients With Cirrhosis and a Low Model for End-Stage Liver Disease Sodium Score (≤15): An Analysis of Liver Transplant Allocation Policy Using Aggregated Electronic Health Record Data

Although the Model for End-Stage Liver Disease sodium (MELD Na) score is now used for liver transplant allocation in the United States, mortality prediction may be underestimated by the score. Using aggregated electronic health record data from 7834 adult patients with cirrhosis, we determined whether the cause of cirrhosis or cirrhosis complications was associated with an increased risk of death among patients with a MELD Na score ≤15 and whether patients with the greatest risk of death could benefit from liver transplantation (LT). Over median follow-up of 2.3 years, 3715 patients had a maximum MELD Na score ≤15. Overall, 3.4% were waitlisted for LT. Severe hypoalbuminemia, hepatorenal syndrome, and hepatic hydrothorax conferred the greatest risk of death independent of MELD Na score with 1-year predicted mortality >14%. Approximately 10% possessed these risk factors. Of these high-risk patients, only 4% were waitlisted for LT, despite no difference in nonliver comorbidities between waitlisted patients and those not listed. In addition, risk factors for death among waitlisted patients were the same as those for patients not waitlisted, although the effect of malnutrition was significantly greater for waitlisted patients (hazard ratio 8.65 [95% CI 2.57-29.11] vs. 1.47 [95% CI 1.08-1.98]). Using the MELD Na score for allocation may continue to limit access to LT.
