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.

Malabsorption, weight loss and vitamin/mineral-deficiencies characterize classical celiac disease (CD). This study aimed to assess the nutritional and vitamin/mineral status of current “early diagnosed” untreated adult CD-patients in the Netherlands. Newly diagnosed adult CD-patients were included (n = 80, 42.8 ± 15.1 years) and a comparable sample of 24 healthy Dutch subjects was added to compare vitamin concentrations. Nutritional status and serum concentrations of folic acid, vitamin A, B6, B12, and (25-hydroxy) D, zinc, haemoglobin (Hb) and ferritin were determined (before prescribing gluten free diet). Almost all CD-patients (87%) had at least one value below the lower limit of reference. Specifically, for vitamin A, 7.5% of patients showed deficient levels, for vitamin B6 14.5%, folic acid 20%, and vitamin B12 19%. Likewise, zinc deficiency was observed in 67% of the CD-patients, 46% had decreased iron storage, and 32% had anaemia. Overall, 17% were malnourished (>10% undesired weight loss), 22% of the women were underweight (Body Mass Index (BMI) < 18.5), and 29% of the patients were overweight (BMI > 25). Vitamin deficiencies were barely seen in healthy controls, with the exception of vitamin B12. Vitamin/mineral deficiencies were counter-intuitively not associated with a (higher) grade of histological intestinal damage or (impaired) nutritional status. In conclusion, vitamin/mineral deficiencies are still common in newly “early diagnosed” CD-patients, even though the prevalence of obesity at initial diagnosis is rising. Extensive nutritional assessments seem warranted to guide nutritional advices and follow-up in CD treatment.

OBJECTIVE Although screening for malnutrition in health care has expanded enormously, a gold standard for the optimal definition and operationalism of malnutrition is still lacking. This report reflects expert opinions on the elements of the definition and operationalism of malnutrition and is meant to trigger further debate within the nutritional societies. METHODS A Delphi study was performed consisting of three phases. After a literature review (phase 1), questions for a semistructured interviews (phase 2) were formulated. Subsequently, the results of these semistructured interviews were used to develop the final list of elements (for defining and operationalism of malnutrition). In phase 3 (final phase), experts were asked to provide written feedback regarding the ranking of elements concerning the importance of these elements. RESULTS Twenty-two experts (response 73.3%) were included in the final phase of this Delphi study. No overall agreement could be reached. The elements deficiencies of energy or protein and decrease in fat-free mass were most often mentioned to be particularly important in defining malnutrition. Elements mentioned to be important in operationalism of malnutrition were involuntary weight loss, body mass index, and no nutritional intake. Opinions on cutoff points regarding these elements differed strongly among experts. CONCLUSION This study shows that there is no full agreement among experts on the elements defining and operationalism of malnutrition. The results of this study may fuel the discussion within the nutritional societies, which will most ideally lead to an international consensus on a definition and operationalism of malnutrition.

OBJECTIVE In most health care organizations there is still insufficient awareness for recognizing and treating malnourished patients. To gain more insight into nutritional care policies in Dutch health care organizations, this study investigated screening, treatment, and other quality indicators of nutritional care. METHODS In 2007 a cross-sectional multicenter study was performed that included 20 255 patients (hospitals, n = 6021; nursing homes, n = 11 902; home care, n = 2332). A standardized questionnaire was used to study nutritional screening and treatment at the patient level and quality indicators at institutional and ward levels (e.g., malnutrition guidelines/protocols, nutritional education, and weighing policy). RESULTS Nutritional screening was performed more often in nursing homes (60.2%) than in hospitals (40.3%) and home care (13.9%, P < 0.001). In general, one in every five patients was malnourished, and nutritional treatment was applied in fewer than 50% of all malnourished patients in nursing homes, hospitals, and home care. At ward level nursing homes focused more on the quality of nutritional care than did hospitals and home care, especially with respect to controlling the use of nutritional guidelines (54.6%, P < 0.03), weighing at admission (82.9%, P < 0.01), and mealtime ambiance (91.8%, P < 0.01). CONCLUSION This large-scale study shows that malnutrition is still a considerable problem in one of every five patients in all participating health care settings. It furthermore demonstrates that recognizing and treating malnutrition continues to be problematic. To target the problem of malnutrition adequately, more awareness is needed of the importance of nutritional screening, appropriate treatment, and other nutritional quality indicators.

AIMS AND OBJECTIVES The purpose of this study is to compare five commonly used malnutrition screening tools against an acknowledged definition of malnutrition in one hospital inpatient sample. BACKGROUND Early identification and intervention of malnutrition in hospital patients may prevent later complications. Several screening tools have reported their diagnostic accuracy, but the criterion validity of these tools is unknown. DESIGN A cross sectional study. METHODS We compared quick-and easy screening tools [Malnutrition Screening Tool (MST), Short Nutritional Assessment Questionnaire (SNAQ) and Mini-Nutritional Assessment Short Form (MNA-SF)] and more comprehensive malnutrition screening tools [Malnutrition Universal Screening Tool (MUST) and Nutritional Risk Screening 2002 (NRS-2002)] to an acknowledged definition of malnutrition (including low Body Mass Index and unintentional weight loss) in one sample of 275 adult hospital inpatients. Sensitivity, specificity, positive predictive value and negative predictive value were determined. A sensitivity and specificity of ≥ 70% was set as a prerequisite for adequate performance of a screening tool. RESULTS According to the acknowledged definition of malnutrition 5% of patients were at moderate risk of malnutrition and 25% were at severe risk. The comprehensive malnutrition screening tools (MUST, NRS-2002) and the quick-and-easy malnutrition screening tools (MST and SNAQ) showed sensitivities and specificities of ≥70%. However, 47% of data were missing on the MUST questionnaire and 41% were missing on MNA-SF. The MNA-SF showed excellent sensitivity, but poor specificity for the older subpopulation. CONCLUSIONS The quick-and-easy malnutrition screening tools (MST and SNAQ) are suitable for use in an hospital inpatient setting. They performed as well as the comprehensive malnutrition screening tools (MUST and NRS-2002) on criterion validity. However, MUST was found to be less applicable due to the high rate of missing values. The MNA-SF appeared to be not useful because of it low specificity. RELEVANCE TO CLINICAL PRACTICE Insight in what is the most valid and practical nutritional screening tool to use in hospital practice will increase effective recognition and treatment of malnutrition.

BACKGROUND Older people are vulnerable to malnutrition, which leads to negative outcomes. This study evaluates the effectiveness of nutritional supplementation in malnourished elderly patients after hospital discharge. METHODS Hospital-admitted malnourished elderly patients (≥ 60 years) were randomized to receive either nutritional supplementation (energy and protein enriched diet, oral nutritional support, calcium-vitamin D supplement, telephone counseling by a dietitian) for 3 months postdischarge or usual care. Outcomes were functional limitations, physical performance, physical activities, body weight, fat-free mass, and handgrip strength. Measurements were performed at hospital admission (baseline) and at 3 months after discharge. Data were analyzed according to the intention-to-treat principle. FINDINGS A total of 210 patients were included, 105 in each group. Body weight increased more in the intervention group than in the control group; this was significant for the highest body weight category (mean difference 3.4 kg, 95% CI 0.2-6.6). Functional limitations decreased more (mean difference -0.5 (95% CI -1.0-0.1) in the intervention group than in the control group. When excluding patients who had already received nutritional support before the start of the study, this reached significance. No significant differences could be demonstrated for physical performance, physical activities, fat-free mass, or handgrip strength. INTERPRETATION Three months of oral nutritional support to malnourished elderly decreased functional limitations and increased body weight. It can be questioned if a follow-up of only 3 months was not too short to detect differences on physical performance and physical activities as well.

BACKGROUND Plasma arginine concentrations are lower in patients with cancer, which indicates that arginine metabolism may be disturbed in these patients. Arginine supplementation has been associated with positive effects on antitumor mechanisms and has been shown to reduce tumor growth and to prolong survival. Furthermore, the prognosis of patients with head and neck cancer remains disappointing. Insufficient intake frequently leads to malnutrition, which contributes to high morbidity and mortality rates. OBJECTIVE The aim of this study was to assess the long-term effects of perioperative arginine supplementation in severely malnourished patients with head and neck cancer. DESIGN In this double-blind, randomized, controlled trial, we randomly assigned 32 severely malnourished patients with head and neck cancer to receive 1) standard perioperative enteral nutrition (n = 15) or 2) arginine-supplemented perioperative enteral nutrition (n = 17). The primary outcome was long-term (≥10 y) survival. Secondary outcomes included the long-term appearance of locoregional recurrence, distant metastases, and second primary tumors. RESULTS No significant differences in baseline characteristics were observed between groups. The group receiving arginine-enriched nutrition had a significantly better overall survival (P = 0.019) and better disease-specific survival (P = 0.022). Furthermore, the arginine-supplemented group had a significantly better locoregional recurrence-free survival (P = 0.027). No significant difference in the occurrence of distant metastases or occurrence of a second primary tumor was observed between the groups. CONCLUSION Perioperative arginine-enriched enteral nutrition significantly improved the long-term overall survival and long-term disease-specific survival in malnourished patients with head and neck cancer.

Background. Low body mass index is a general measure of thinness. However, its measurement can be cumbersome in older persons and other simple anthropometric measures may be more strongly associated with mortality. Therefore, associations of low mid-upper arm circumference, calf circumference, and body mass index with mortality were examined in older persons. Methods. Data of the Longitudinal Aging Study Amsterdam, a population-based cohort study in the Netherlands, were used. The present study included community-dwelling persons 65 years and older in 1992–1993 (n = 1,667), who were followed until 2007 for their vital status. Associations between anthropometric measures and 15-year mortality were examined by spline regression models and, below the nadir, Cox regression models, transforming all measures to sex-specific Z scores. Results. Mortality rates were 599 of 826 (73%) in men and 479 of 841 (57%) in women. Below the nadir, the hazard ratio of mortality per 1 standard deviation lower mid-upper arm circumference was 1.79 (95% confidence interval, 1.48–2.16) in men and 2.26 (1.71–3.00) in women. For calf circumference, the hazard ratio was 1.45 (1.22–1.71) in men and 1.30 (1.15–1.48) in women and for body mass index 1.38 (1.17–1.61) in men and 1.56 (1.10–2.21) in women. Excluding deaths within the first 3 years after baseline did not change these associations. Excluding those with a smoking history, obstructive lung disease, or cancer attenuated the associations of calf circumference (men) and body mass index (women). Conclusions. Based on the stronger association with mortality and given a more easy assessment in older persons, mid-upper arm circumference seems a more feasible and valid anthropometric measure of thinness than body mass index in older men and women.

BACKGROUND & AIMS Few data is available on the nutritional status of geriatric outpatients. The aim of this study is to describe the nutritional status and its clinical correlates of independently living geriatric older individuals visiting a geriatric outpatient department. METHODS From 2005 to 2010, all consecutive patients visiting a geriatric outpatient department in the Netherlands were screened for malnutrition. Nutritional status was assessed by the Mini Nutritional Assessment (MNA). Determinants of malnutrition were categorized into somatic factors (medicine use, comorbidity, walking aid, falls, urinary incontinence), psychological factors (GDS-15 depression scale, MMSE cognition scale), functional status (Activities of Daily Life (ADL), Instrumental ADL (IADL)), social factors (children, marital status), and life style factors (smoking, alcohol use). Univariate and multivariate logistic regression analyses, adjusted for age and sex and all other risk factors were performed to identify correlates of malnutrition (MNA < 17). RESULTS Included were 448 outpatients, mean (SD) age was 80 (7) years and 38% was men. Prevalence of malnutrition and risk for malnutrition were 17% and 58%. Depression, being IADL dependent, and smoking were independently associated with an increased risk of malnutrition with ORs (95%CI) of 2.6 (1.3-5.3), 2.8 (1.3-6.4), 5.5 (1.9-16.4) respectively. Alcohol use was associated with a decreased risk (OR 0.4 (0.2-0.9)). CONCLUSION Malnutrition is highly prevalent among geriatric outpatients and is independently associated with depressive symptoms, poor functional status, and life style factors. Our results emphasize the importance of integrating nutritional assessment within a comprehensive geriatric assessment. Future longitudinal studies should be performed to examine the effects of causal relationships and multifactorial interventions.
