Mini-Nutritional Assessment, Malnutrition Universal Screening Tool, and Nutrition Risk Screening Tool for the Nutritional Evaluation of Older Nursing Home Residents.

Malnutrition plays a major role in clinical and functional impairment in older adults. The use of validated, user-friendly and rapid screening tools for malnutrition in the elderly may improve the diagnosis and, possibly, the prognosis. The aim of this study was to assess the agreement between Mini-Nutritional Assessment (MNA), considered as a reference tool, MNA short form (MNA-SF), Malnutrition Universal Screening Tool (MUST), and Nutrition Risk Screening (NRS-2002) in elderly institutionalized participants. Participants were enrolled among nursing home residents and underwent a multidimensional evaluation. Predictive value and survival analysis were performed to compare the nutritional classifications obtained from the different tools. A total of 246 participants (164 women, age: 82.3 ± 9 years, and 82 men, age: 76.5 ± 11 years) were enrolled. Based on MNA, 22.6% of females and 17% of males were classified as malnourished; 56.7% of women and 61% of men were at risk of malnutrition. Agreement between MNA and MUST or NRS-2002 was classified as "fair" (k = 0.270 and 0.291, respectively; P < .001), whereas the agreement between MNA and MNA-SF was classified as "moderate" (k = 0.588; P < .001). Because of the high percentage of false negative participants, MUST and NRS-2002 presented a low overall predictive value compared with MNA and MNA-SF. Clinical parameters were significantly different in false negative participants with MUST or NRS-2002 from true negative and true positive individuals using the reference tool. For all screening tools, there was a significant association between malnutrition and mortality. MNA showed the best predictive value for survival among well-nourished participants. Functional, psychological, and cognitive parameters, not considered in MUST and NRS-2002 tools, are probably more important risk factors for malnutrition than acute illness in geriatric long-term care inpatient settings and may account for the low predictive value of these tests. MNA-SF seems to combine the predictive capacity of the full version of the MNA with a sufficiently short time of administration.

Evaluation of the nutritional status of older hospitalised geriatric patients: a comparative analysis of a Mini Nutritional Assessment (MNA) version and the Nutritional Risk Screening (NRS 2002).

The present study aimed to evaluate a short-form (MNA-SF) version of the Mini Nutritional Assessment (MNA), in which some of the items were operationalised, based on scores from tools used for a comprehensive geriatric assessment, as a method for analysing the nutritional status of hospitalised geriatric patients. We compared this MNA-SF version with the corresponding MNA long-form (MNA-LF) and Nutritional Risk Screening 2002 (NRS 2002) in terms of completion rate, prevalence and agreement regarding malnutrition and/or the risk of this. In total, 201 patients aged ≥65 years who were hospitalised in geriatric wards were included in this analysis. The MNA-SF, MNA-LF and NRS 2002 were completed in 98.0%, 95.5% and 99.5% of patients (P = 0.06), respectively. The MNA-SF, MNA-LF and NRS 2002 categorised 93.4%, 91.1% and 66.0% of patients as being malnourished or at risk of being malnourished (P < 0.001). Agreement between the MNA-SF and MNA-LF was substantial (κ = 0.70, P < 0.001). No agreement between the MNA-SF and NRS 2002 was found (κ = -0.12, P < 0.001). Interestingly, NRS 2002 part 1 (prescreening) revealed a false negative rate of 21.0% (only in patients aged ≥70 years who showed moderate disease severity) in relation to the NRS 2002 part 2. The MNA-SF version emerged as a useful tool for evaluating the nutritional status of hospitalised geriatric patients. The NRS 2002 part 1 showed limited value as a prescreening aid in relation to the NRS 2002 part 2 in the same group of patients.

Beyond malnutrition screening: appropriate methods to guide nutrition care for aged care residents.

Malnutrition is common in older adults and early and appropriate nutrition intervention can lead to positive quality of life and health outcomes. The purpose of our study was to determine the concurrent validity of several malnutrition screening tools and anthropometric parameters against validated nutrition assessment tools in the long-term-care setting. This work was a cross-sectional, observational study. Older adults (aged >55 years) from two long-term-care facilities were screened. Nutrition screening tools used included the Malnutrition Screening Tool (MST), Malnutrition Universal Screening Tool (MUST), Mini Nutritional Assessment-Short Form (MNA-SF), and the Simplified Nutritional Assessment Questionnaire. Nutritional status was assessed by Subjective Global Assessment (SGA), Mini Nutritional Assessment (MNA), body mass index (BMI), corrected arm muscle area, and calf circumference. Residents were rated as either well nourished or malnourished according to each nutrition assessment tool. A contingency table was used to determine the sensitivity and specificity of the nutrition screening tools and objective measures in detecting patients at risk of malnutrition compared with the SGA and MNA. One hundred twenty-seven residents (31.5% men; mean age 82.7 ± 9 years, 57.5% high care) consented. According to SGA, 27.6% (n=31) of residents were malnourished and 13.4% were rated as malnourished by MNA. MST had the best sensitivity and specificity compared with the SGA (sensitivity 88.6%, specificity 93.5%, ?=0.806), followed by MNA-SF (85.7%, 62%, ?=0.377), MUST (68.6%, 96.7%, ?=0.703), and Simplified Nutritional Assessment Questionnaire (45.7%, 77.2%, ?=0.225). Compared with MNA, MNA-SF had the highest sensitivity of 100%, but specificity was 56.4% (?=0.257). MST compared with MNA had a sensitivity of 94.1%, specificity 80.9% (?=0.501). The anthropometric screens ranged from ?=0.193 to 0.468 when compared with SGA and MNA. MST, MUST, MNA-SF, and the anthropometric screens corrected arm muscle area and calf circumference have acceptable concurrent validity compared with validated nutrition assessment tools and can be used to triage nutrition care in the long-term-care setting.

Comparing the adequacy of the MNA-SF, NRS-2002 and MUST nutritional tools in assessing malnutrition in hip fracture operated elderly patients.

Malnutrition is common in hip fracture elderly patients. There is no gold standard for screening nutritional risk. We compared the adequacy of 3 screening tools, their association to nutritional measurements and their ability to predict outcome. The Mini Nutrition Assessment Short Form (MNA-SF), the Malnutrition Universal Screening Tool (MUST) and the Nutrition Risk Screening 2002 (NRS-2002) were prospectively determined. Length of stay (LOS), complications, 6 months readmission and up-to 36 months mortality were recorded. 215 operated patients were included: 154 (71.6%) were women; mean age was 83.5 ± 6.09 years (66-104). According to the MNA-SF, 95 patients were well-nourished, 95 were at risk of malnutrition and 25 were malnourished. Based on the MUST, 171 patients were at a low risk of malnutrition, 31 at a medium risk, 13 at a high risk. According to the NRS-2002, 134 patients were at a low risk of malnutrition, 70 at a medium risk, 11 at a high risk. A significant relationship between the nutritional groups of the 3 scores (p < 0.001) was found. In all screening tools, body mass index, weight loss and food intake prior to admission were found to be related to the patients' nutritional status (p < 0.001). No differences in LOS and complications were found between the patients' nutritional status of each screening tool; only the MNA-SF predicted that well-nourished patients would have less readmissions during a 6 month follow-up (p = 0.024). During a 36 month follow-up, 79 patients died. According to the MNA-SF, mortality was lower in the well-nourished patients vs. the malnourished (p = 0.001) and at risk of malnutrition patients (p = 0.01). A less significant association was found between the NRS-2002 patients' nutritional status and mortality (p = 0.048). The MUST did not reveal this relationship. All screening tools were adequate in assessing malnutrition parameters in hip fracture operated elderly patients, however, only the MNA-SF could also predict readmissions and mortality.
