Malnutrition in Hospitalized Old Patients: Screening and Diagnosis,Clinical Outcomes,and Management

Malnutrition in hospitalized patients heavily affects several clinical outcomes. The prevalence of malnutrition increases with age, comorbidities, and intensity of care in up to 90% of old populations. However, malnutrition frequently remains underdiagnosed and undertreated in the hospital. Thus, an accurate screening to identify patients at risk of malnutrition or malnourishment is determinant to elaborate a personal nutritional intervention. Several definitions of malnutrition were proposed in the last years, affecting the real frequency of nutritional disorders and the timing of intervention. Diagnosis of malnutrition needs a complete nutritional assessment, which is often challenging to perform during a hospital stay. For this purpose, various screening tools were proposed, allowing patients to be stratified according to the risk of malnutrition. The present review aims to summarize the actual evidence in terms of diagnosis, association with clinical outcomes, and management of malnutrition in a hospital setting.     

Prognostic impact of disease-related malnutrition

This review focuses on the studies investigating the prognostic implications of disease-related malnutrition. Malnutrition is a common problem in patients with chronic or severe diseases. Prevalence of hospital malnutrition ranges between 20% and 50% depending on the criteria used in order to determine malnutrition and the patient's characteristics. Furthermore, nutritional status is known to worsen during hospital stay which is partly due to the poor recognition by the medical staff and adverse clinical routines. Studies have repeatedly shown that clinical malnutrition however has serious implications for recovery from disease, trauma and surgery and is generally associated with increased morbidity and mortality both in acute and chronic diseases. Length of hospital stay is significantly longer in malnourished patients and higher treatment costs are reported in malnutrition. Since it has been demonstrated that proper nutritional care can reduce the prevalence of hospital malnutrition and costs, nutritional assessment is mandatory in order to recognise malnutrition early and initiate timely nutritional therapy.     

Moderate-to-Severe Malnutrition Identified by the Controlling Nutritional Status (CONUT) Score Is Significantly Associated with Treatment Failure of Periprosthetic Joint Infection

The prevalence and role of malnutrition in periprosthetic joint infection (PJI) remain unclear. This study aimed to use measurable nutritional screening tools to assess the prevalence of malnutrition in PJI patients during two-stage exchange arthroplasty and to explore the association between malnutrition and treatment failure. Our study retrospectively included 183 PJI cases who underwent 1st stage exchange arthroplasty and had available nutritional parameters, of which 167 proceeded with 2nd stage reimplantation. The recently proposed Musculoskeletal Infection Society (MSIS) Outcome Reporting Tool was used to determine clinical outcomes. The Controlling Nutritional Status (CONUT), Nutritional Risk Index (NRI), and Naples Prognostic Score (NPS) were used to identify malnutrition at 1st and 2nd stage exchange, respectively. Multivariate logistic regression analyses were performed to determine the association between malnutrition and treatment failure. Restricted cubic spline models were further used to explore the dose–response association. Additionally, risk factors for moderate-to-severe malnutrition were evaluated. Malnourished patients identified by CONUT, NPS, and NRI accounted for 48.1% (88/183), 98.9% (181/183), and 55.7% (102/183) of patients at 1st stage, and 9.0% (15/167), 41.9% (70/167), and 43.1% (72/167) at 2nd stage, indicating a significant improvement in nutritional status. We found that poorer nutritional status was a predictor of treatment failure, with CONUT performing best as a predictive tool. Moderate-to-severe malnutrition at 1st stage identified by CONUT was significantly related to treatment failure directly caused by PJI (odds ratio [OR] = 5.86), while the OR was raised to 12.15 at 2nd stage (OR = 12.15). The linear dose–response associations between them were also confirmed (P for nonlinearity at both 1st and 2nd stage > 0.05). As for total treatment failure, moderate-to-severe malnutrition as determined by CONUT was associated with a 1.96-fold and 8.99-fold elevated risk at the 1st and 2nd stages, respectively. Age ≥ 68 years (OR = 5.35) and an increased number of previous surgeries (OR = 2.04) may be risk factors for moderate-to-severe malnutrition. Overall, the prevalence of malnutrition in PJI patients is very high. Given the strong association between moderate-to-severe malnutrition identified by CONUT and PJI treatment failure, COUNT could be a promising tool to evaluate the nutritional status of PJI patients to optimize treatment outcomes.     

Malnutrition and Increased Risk of Adverse Outcomes in Elderly Patients Undergoing Elective Colorectal Cancer Surgery: A Case-Control Study Nested in a Cohort

Background: Malnutrition increases worse outcomes during hospital admission for elective colorectal cancer (CRC) surgery in older adults. Methods: This work was designed an observational, monocentric, case-control study nested in a cohort of patients undergoing elective surgery for CRC disease at the Hospital Universitario de la Ribera (HULR) (Alzira, Valencia, Spain) between 2011 and 2019. The study considered patients with a CONUT score in the range of moderate to severe malnutrition (>4 points), with control patients with normal nutritional situations or mild malnutrition. Results: Moderate-to-severe malnutrition cases presented a greater length of stay (LOS), a higher incidence of adverse events (both medical and surgical complications), a higher incidence of surgical-wound infection, a greater need for blood transfusion, and a greater amount of transfused packed red blood cells. During hospitalization, the percentage of patients without nutritional risk decreased from 46 to 9%, and an increase in mild, moderate, and severe risk was observed. Patients with severe nutritional risk at hospital admission had significantly increased mortality at 365 days after discharge (HR: 2.96 (95% CI 1.14–7.70, p = 0.002)). After adjusting for sex, age, and Charlson index score, patients with severe nutritional risk at admission maintained a higher mortality risk (HR: 3.08 (95% CI 1.10–8.63, p = 0.032)). Conclusion: Malnutrition prevalence is high in older adults undergoing CRC elective surgery. Furthermore, this prevalence increases during hospital admission. Malnutrition is linked to worse outcomes, such as LOS, surgical and clinical complications, and mortality. For this reason, nutritional interventions are very important in the perioperative period     

Assessment of nutritional status on hospital admission: nutritional scores

Malnutrition is still a largely unrecognized problem in hospitals. Malnutrition in hospitalized patients is generally related to increasing morbidity and mortality, and costs and length of stay. The aim of this study was to assess the nutritional status of patients on admission to a general hospital using different nutritional scores and to test the sensitivity and specificity of these scores. Sample population included 60 patients (55% male; 45% female) selected (aged 65.6+/-15.9 y) at random by using a computer software program. The nutritional state assessment was performed within 48 h of admission, using different nutritional indices (Subjective Global Assessment (SGA), Nutritional Risk Index (NRI), Gassull classification, Instant Nutritional Assessment (INA) and a combined index). About 78.3% of patients were found to be malnourished on admission. The frequency of malnutrition degree varied from 63.3% as assessed by the SGA to 90% with the NRI. Malnutrition severity was not related to the diagnosis. However, an elderly population was associated with a higher prevalence of malnutrition. INA was the best single score to identify patients who are malnourished or at risk of malnutrition and who may benefit from nutrition support.     

The prevalence of malnutrition in spinal cord injuries patients: a UK multicentre study

Data on the prevalence of malnutrition among patients with spinal cord injuries (SCI) are lacking. The aim of the present study was to assess nutritional risk at admission, and the status of nutritional support in the UK SCI Centres (SCIC); a cross-sectional, multicentre study in four SCIC. A standardised questionnaire was used and distributed to the participating SCIC. After obtaining informed consent, baseline demographic data, nutritional risk score by the 'Malnutrition Universal Screening Tool', BMI and routine blood biochemistry were collected from every patient admitted to an SCIC. The four SCIC, comprising 48·2?% of the total UK SCI beds, contributed data from 150 patients. On admission, 44·3?% of patients were malnourished or at risk of undernutrition. Nutritional risk was more common in patients with acute high cervical SCI than those with lower SCI (60·7 v. 34·5?%), and nutritional risk was more common in those with additional complications including ventilatory support (with tracheostomy, 56·3 v. 38·7?%). Also, 45?% of patients were at risk of overnutrition (BMI?≥?25?kg/m2). The prevalence of malnutrition in SCI patients admitted to SCIC is higher than national figures focused on general hospitalised patients, indicating that SCI patients are particularly vulnerable to malnutrition. Patients with SCI who have a tracheostomy may need additional attention. Given the potential negative impact of malnutrition on clinical outcomes, an emphasis on mandatory nutrition screening, followed by detailed assessment for at-risk individuals should be in place in the SCIC.     

Overview of gastrointestinal disorders due to diabetes mellitus: emphasis on nutritional support

Gastrointestinal disorders associated with diabetes mellitus have a prevalence rate of 30 to 75%. The most prominent disorders are gastroparesis, diarrhea, and constipation. Severity of symptoms range from mild to severe with the most affected patients being at risk for the development of protein calorie malnutrition. An historical review of the major studies which defined the diagnosis, pathophysiology, and prevalence of these disorders is presented. Guidelines for accurate nutritional assessment, which is essential to the decision to initiate nutritional therapy in this difficult to assess population, are also included. Current methods devised for treatment of diabetic gastroparesis and related disorders are presented. Emphasis is placed on recent developments in nutritional support techniques which make it possible to meet the energy requirements of all such patients. Practical outlines for glucose control in patients receiving TPN or enteral feeding and guidelines for transitioning from parenteral feeding to an oral diet are also presented.     

To screen or not to screen for adult malnutrition?

BACKGROUND: There is some controversy about whether all adults receiving healthcare should be routinely screened for nutritional problems. METHODS: (i) A systematic review examined the proposition that malnutrition is under-recognised and under-treated, and that nutritional interventions in malnourished patients, identified through a screening procedure produce clinical benefits (assessed using randomised controlled trials, RCTs). (ii) A systematic review of nutritional screening interventions in populations of malnourished and well-nourished subjects (RCTs and non-RCTs). RESULTS: (i) The prevalence of malnutrition varies according to the criteria used, but is estimated to affect 10-60% of patients in hospital and nursing homes, 10% or more of older free-living subjects, and less than 5% of younger adults. In the absence of formal screening procedures, more than half the patients at risk of malnutrition in various settings do not appear to be recognised and/or are not referred for treatment. RCTs show that nutritional interventions in malnourished patients produce various clinical benefits. (ii) Interventions with nutritional screening in different care settings also generally suggest clinical benefits, but some are limited by small sample sizes and inadequate methodology. Factors that influence outcomes include validity, reliability and ease of using the screening procedure, the 'care gap' that exists between routine and desirable care and the need for other resources, which may increase or decrease following screening. CONCLUSIONS: The frequent failure to recognise and treat malnutrition, especially where it is common, is unacceptable. In such circumstances, the routine use of a simple screening procedure is recommended. Each health care setting should have a transparent policy about nutritional screening, which may vary according to the 'care gap', available resources, and specific populations of patients, in which the prevalence of malnutrition may vary widely.     

Prevalence of malnutrition and nutritional risk factors in patients undergoing alcohol and drug treatment

ObjectiveChronic substance abuse is recognized to affect nutritional status and is associated with nutrient deficiencies and malnutrition. This study aimed to identify the prevalence of malnutrition and nutritional risk factors using a spread of measurements in patients undergoing alcohol and drug treatment.MethodsSixty-seven patients (48 male, 19 female) admitted to a public hospital detoxification unit participated: 49 were alcohol dependent (73%) and the remaining were opiate, benzodiazepine, and/or amphetamine dependent. Nutritional status was assessed by the Subjective Global Assessment. An appetite questionnaire (Simplified Nutritional Appetite Questionnaire), a diet-quality questionnaire (Australian Recommended Food Score), and blood biochemistry and hematologic tests were also applied.ResultsThe prevalence of mild/moderate malnutrition was 24% according to the Subjective Global Assessment. Weight and body mass index were associated with nutritional status (P < 0.05). Appetite and diet quality were poor overall, with 88% of all participants requiring advice and guidance. Blood markers showed that 50% of all subjects were deficient in iron or vitamins (low vitamin A levels in 21%, low iron levels in 18%, low-range potassium in 12%, and low vitamin C levels in 8%).ConclusionThe prevalence of malnutrition in this patient population is likely to underestimate the prevalence of nutritional risk factors and micronutrient undernutrition. Multiple tools assessing nutritional status, appetite, diet quality, and blood test results have different advantages and can further identify the specific needs and appropriateness of nutritional education in patients during treatment for drug and alcohol use.     

Malnutrition prevalence in The Netherlands: results of the annual dutch national prevalence measurement of care problems

The objective of this study was to provide data on malnutrition prevalence in hospitals, nursing homes and home-care organisations in The Netherlands in a nationally representative sample, and to assess the factors such as age, sex, time since admission, ward type and disease for identifying patients at high risk of malnutrition. A cross-sectional, multi-centre design with a standardised questionnaire was used to measure the prevalence of malnutrition. Nutritional status was assessed by BMI, undesired weight loss and nutritional intake. In this study, 12 883 patients were included. The prevalence of malnutrition was the highest in hospitals (23.8 %), followed by home-care organisations (21.7 %) and nursing homes (19.2 %). Logistic regression analysis revealed no association with age, time since admission and ward type. Being female was associated with malnutrition only in nursing homes. Blood diseases, gastrointestinal tract diseases, infection, chronic obstructive pulmonary disease, dementia and cancer were the factors associated with malnutrition in hospitals. Dementia was associated with malnutrition in nursing homes, while gastrointestinal tract diseases, diabetes mellitus and cancer were the associated factors in home care. This study shows that malnutrition is still a substantial problem in hospitals, nursing homes and home care in The Netherlands. Malnutrition is a problem for more than one in five patients. Despite growing attention to the problem, more continued alertness is required.     

Marqueurs de la dénutrition et de son risque ou marqueurs des complications liées à la dénutrition ?

Malnutrition has been frequently reported in patients at hospital admission and this worsens during hospital stay. Malnutrition is associated with an increase in complication risk. Screening nutritional risk remains difficult because there is no absolute diagnosis criterion (i-e. no gold standard). Many assessment tools exist, but none is entirely satisfactory in terms of sensitivity and/or specificity. Composite formulas make it possible to be more sensitive and specific. It is necessary however to differentiate the markers of malnutrition (or indicating patients at risk of malnutrition) from the markers of complications related to malnutrition. Indeed, the first one detects malnutrition or the risk to be undernourished (SGA, MNA, or BMI), whereas the second's one allows to quantify a risk of complications dependent of malnutrition (NRI or Nutritional Risk Index). At the beginning, NRI was associated with an increase in morbimortality in surgical patients for values lower than 97,5. Thereafter, several authors claimed that NRI is a marker of malnutrition. In practice, such a misconception can have clinical consequences: a patient can be malnourished without any risk of complication or mortality. Moreover, we believe that the important is not that a patient is malnourished but that its malnutrition increases its morbimortality, and this is in this latest case that nutritional intervention seems to be justified. Such a rationale approach should allow to save money and avoid a certain number of cases of non-justified nutritional assistance.     

Association Between Malnutrition and Clinical Outcomes in the Intensive Care Unit: A Systematic Review

Malnutrition is associated with poor clinical outcomes among hospitalized patients. However, studies linking malnutrition with poor clinical outcomes in the intensive care unit (ICU) often have conflicting findings due in part to the inappropriate diagnosis of malnutrition. We primarily aimed to determine whether malnutrition diagnosed by validated nutrition assessment tools such as the Subjective Global Assessment (SGA) or Mini Nutritional Assessment (MNA) is independently associated with poorer clinical outcomes in the ICU and if the use of nutrition screening tools demonstrate a similar association. PubMed, CINAHL, Scopus, and Cochrane Library were systematically searched for eligible studies. Search terms included were synonyms of malnutrition, nutritional status, screening, assessment, and intensive care unit. Eligible studies were case‐control or cohort studies that recruited adults in the ICU; conducted the SGA, MNA, or used nutrition screening tools before or within 48 hours of ICU admission; and reported the prevalence of malnutrition and relevant clinical outcomes including mortality, length of stay (LOS), and incidence of infection (IOI). Twenty of 1168 studies were eligible. The prevalence of malnutrition ranged from 38% to 78%. Malnutrition diagnosed by nutrition assessments was independently associated with increased ICU LOS, ICU readmission, IOI, and the risk of hospital mortality. The SGA clearly had better predictive validity than the MNA. The association between malnutrition risk determined by nutrition screening was less consistent. Malnutrition is independently associated with poorer clinical outcomes in the ICU. Compared with nutrition assessment tools, the predictive validity of nutrition screening tools were less consistent.     

The German hospital malnutrition study

BACKGROUND & AIMS: Malnutrition is frequently observed in chronic and severe diseases and associated with impaired outcome. In Germany general data on prevalence and impact of hospital malnutrition are missing. METHODS: Nutritional state was assessed by subjective global assessment (SGA) and by anthropometric measurements in 1,886 consecutively admitted patients in 13 hospitals (n=1,073, university hospitals; n=813, community or teaching hospitals). Risk factors for malnutrition and the impact of nutritional status on length of hospital stay were analyzed. RESULTS: Malnutrition was diagnosed in 27.4% of patients according to SGA. A low arm muscle area and arm fat area were observed in 11.3% and 17.1%, respectively. Forty-three % of patients 70 years old were malnourished compared to only 7.8% of patients <30 years. The highest prevalence of malnutrition was observed in geriatric (56.2%), oncology (37.6%), and gastroenterology (32.6%) departments. Multivariate analysis revealed three independent risk factors: higher age, polypharmacy, and malignant disease (all P<0.01). Malnutrition was associated with an 43% increase of hospital stay (P<0.001). CONCLUSIONS: In German hospitals every fourth patient is malnourished. Malnutrition is associated with increased length of hospital stay. Higher age, malignant disease and major comorbidity were found to be the main contributors to malnutrition. Adequate nutritional support should be initiated in order to optimize the clinical outcome of these patients.     

Stratégies de prise en charge nutritionnelle spécifiques : l'enfant en cancérologie

In children with cancer, malnutrition may antedate the diagnosis or be a result of aggressive chemotherapeutic regimens. The prevalence of malnutrition at diagnosis is related to the type of tumour and the extent of the disease, ranging from < 10% in patients with standard-risk acute lymphoblastic leukaemia to 50% in children with advanced neuroblastoma. The pathogenis of the energy imbalance that underlies the development of malnutrition is complex, including increased breakdown of fat and protein as well as energy-consumptive changes in carbohydrate metabolism (Cori cycle). Despite several confounding factors (different definitions of nutritional status and the wide variety of measures used for its assessment), studies have shown decreased tolerance of chemotherapy associated with altered metabolism of antineoplastic drugs, increased infection rates, altered quality of life and possibly poor clinical outcome in malnourished patients. In this article, we review guidelines for the nutritional management of a child with cancer and we purpose an algorithm for nutritional support.     

The Spectrum of Malnutrition/Cachexia/Sarcopenia in Oncology According to Different Cancer Types and Settings: A Narrative Review

Nutritional status in oncological patients may differ according to several modifiable and non-modifiable factors. Knowledge of the epidemiology of malnutrition/cachexia/sarcopenia may help to manage these complications early in the course of treatment, potentially impacting patient quality of life, treatment intensity, and disease outcome. Therefore, this narrative review aimed to critically evaluate the current evidence on the combined impact of tumor- and treatment-related factors on nutritional status and to draw some practical conclusions to support the multidisciplinary management of malnutrition in cancer patients. A comprehensive literature search was performed from January 2010 to December 2020 using different combinations of pertinent keywords and a critical evaluation of retrieved literature papers was conducted. The results show that the prevalence of weight loss and associated symptoms is quite heterogeneous and needs to be assessed with recognized criteria, thus allowing a clear classification and standardization of therapeutic interventions. There is a large range of variability influenced by age and social factors, comorbidities, and setting of cures (community-dwelling versus hospitalized patients). Tumor subsite is one of the major determinants of malnutrition, with pancreatic, esophageal, and other gastroenteric cancers, head and neck, and lung cancers having the highest prevalence. The advanced stage is also linked to a higher risk of developing malnutrition, as an expression of the relationship between tumor burden, inflammatory status, reduced caloric intake, and malabsorption. Finally, treatment type influences the risk of nutritional issues, both for locoregional approaches (surgery and radiotherapy) and for systemic treatment. Interestingly, personalized approaches based on the selection of the most predictive malnutrition definitions for postoperative complications according to cancer type and knowledge of specific nutritional problems associated with some new agents may positively impact disease course. Sharing common knowledge between oncologists and nutritionists may help to better address and treat malnutrition in this population.     

Proactive screening in Israel identifies alarming prevalence of malnutrition among hospitalized patients--action is needed

ObjectiveMalnourished patients suffer from higher morbidity and mortality rates than well-nourished patients do. However, few studies have controlled the outcomes for the underlying illnesses. Our aim was to determine the prevalence of malnutrition among patients admitted to the internal medicine ward and to determine whether malnutrition is an independent risk factor for adverse outcomes in these settings.MethodsConsecutive patients screened for malnutrition with the MUST (Malnutrition Universal Screening Tool), admitted to an internal medicine department, were included in this study. Demographic data, background disease, laboratory results, length of stay, and mortality rates were retrieved from the computerized file and Charlson Comorbidity Index (CCI) was calculated. Univariate and multivariate analyses were used to check for the association of malnutrition and outcome measures.ResultsOne thousand consecutive patients were included in the study. Mean age was 67.6 y; 25.4% of patients were found to be at high risk for malnutrition. Patients at high risk for malnutrition had significantly longer length of stay and mortality rates than well-nourished patients (9.7 d versus 6.2 d and 19.3% versus 3.2%; accordingly [P < 0.001]). On multivariate analyses, increased mortality was found to be associated with a high risk for malnutrition as well as pneumonia, acute myocardial infarction, acute renal failure, or shock on admission and a high CCI score.ConclusionThe prevalence of malnutrition among hospitalized patients, as measured by the MUST score, is common. Malnutrition is prevalent and represents an independent and significant risk factor for in-hospital mortality and increased length of stay in patients admitted to the internal medicine ward.

Nutritional Status of Adolescent Afghan Refugees Living in Peshawar,Pakistan

Pakistan has hosted millions of Afghan refugees over the last several decades. Due to poor socioeconomic status, food insecurity and inadequate access to health care, these refugees are considered to be at high risk of malnutrition. Previous studies on nutritional assessment of high-risk populations (refugees) have focused mainly on women and children (0–59 months). The current study aims to assess nutritional status of adolescent Afghan refugees; the population who are equally vulnerable to malnutrition and its consequences. In this cross sectional study, the nutritional status of 206 adolescent (10–19 years old) Afghans boys and girls living in a refugee camp in Peshawar, Pakistan was assessed using standard methods. The results indicate a prevalence of stunting, thinness, and overweight and obesity at 35.3%, 4.4% and 14.8%, respectively. Furthermore, there was a significantly high prevalence of micronutrient deficiencies (vitamin D, 80.5%; vitamin B12, 41.9%; and folate, 28.2%); and anemia (10.1%). Together, these findings indicate that this vulnerable population group suffers from the double burden of malnutrition and are thus at serious risk of impaired psychosocial cognitive development, general ill-health and diminished wellbeing. This study therefore highlights the urgent need to include adolescents in regular screening and intervention programs of such at-risk populations.     

Nutrition Screening,Reported Dietary Intake,Hospital Foods,and Malnutrition in Critical Care Patients in Malawi

In low-income countries there are few data on hospital malnutrition. Reduced food intake combined with nutrient-poor foods served in hospitals contribute to nutritional risk. This study investigated whether reported dietary intake and disease state of hospitalized adults in critical care units was related to malnutrition determined by mid-upper arm circumference (MUAC). Adult in-patients (n = 126) in tuberculosis, burn, oncology, and intensive care units in two public tertiary hospitals in Malawi were screened for nutritional status using MUAC and a question on current dietary intake. The hospital menu was reviewed; portion sizes were weighed. The prevalence of moderate and severe malnutrition was 62%. Patients with organ-related diseases and infectious diseases had the highest rates of reduced reported dietary intake, 71.4% and 57.9%, respectively; however, there was no association between reported dietary intake and MUAC. In those unable to eat, however, the rate of severe malnutrition was 50%. The menu consisted of porridge and thickened corn-based starch with fried cabbage; protein foods were provided twice weekly. There was a nutrient gap of 250 calories and 13 gm protein daily. The findings support the need for increasing dietetic/nutrition services to prevent and treat malnutrition in hospitals using simple screening tools.     

The physical functional capacity of frail elderly persons undergoing ambulatory rehabilitation is related to their nutritional status

Objectives: To estimate the prevalence of malnutrition in frail elders undergoing rehabilitation and the association between their nutritional status and physical function.Design: Observational study of new participants undergoing ambulatory rehabilitation.Setting: Two Geriatric Day Hospitals (GDH) in Montreal, Quebec.Participants: 121 women and 61 men.Intervention: Evaluation of nutritional status, body composition and physical function.Measurements: The nutritional status was assessed with a composite index based on anthropometric measurements and serum albumin, as well as using the Mini Nutritional Assessment (MNA) questionnaire. Patients were classified as well-nourished, having mild/at risk of malnutrition or malnourished. Body composition was estimated by bioimpedance and handgrip strength and gait speed by standard methods.Results: 13% of patients were found to be mildly malnourished, whereas 6% were malnourished. Malnourished patients were older and had worse cognition, lower BMI, and % body fat (all p<0.05). Malnourished patients and those with mild malnutrition had lower weight, triceps skinfold thickness, muscle and fat mass (all, p<0.003). Handgrip strength was different according to the nutritional status (p=0.034) and correlated with muscle mass (r=0.65, p<0.001). MNA classified 53% of patients as being at risk whereas 3% were malnourished and it correlated with gait speed (r=0.26, p=0.001).Conclusion: There is a high prevalence of patients in GDH at risk or with mild malnutrition. Being malnourished was associated with worse physical performance, which suggests that a nutritional intervention may be of benefit in improving their physical function. This study was supported by the Helen Hutchinson Foundation of the Division of Geriatric Medicine, Research Institute of the Montreal General Hospital
