“…The Nutritional Risk Index (18,19) is derived from the serum albumin concentration and the ratio of actual to usual weight with the equation Nutritional Risk Index -(1.489 X serum albumin, g/L) -I-41.7 X (present weight/usual weight) (7) A Nutritional Risk Index > 100 indicates that the patient is not malnourished, 97.5-100 mild malnourishment, 83.5 to < 97.5 moderate malnourishment, and < 83.5 severe malnourishment. The usual weight was defined as the stable weight ^ 6 mo before admission.…”

The prevalence of malnutrition and its predictive value for the incidence of complications were determined in 155 patients hospitalized for internal or gastrointestinal diseases. At admission, 45% of the patients were malnourished according to the Subjective Global Assessment (physical examination plus questionnaire), 57% according to the Nutritional Risk Index [(1.5 X albumin) + (41.7 X present/usual weight)], and 62% according to the Maastricht Index [(20.68 -(0.24 X albumin) -(19.21 X transthyretin (prealbumin) -(1.86 X lymphocytes) -(0.04 X ideal weight)]. Crude odds ratios for the incidence of any complication in malnourished compared with well-nourished pa tients during hospitalization were 2.7 (95% Cl: 1

Assessment of nutritional status on hospital admission: nutritional scores

2003

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 65.6715.9 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.

Triagem nutricional em adultos hospitalizados

et al. 2008

Em hospitais, o objetivo de um procedimento de triagem nutricional é identificar indivíduos desnutridos ou em risco de desnutrição, possibilitando intervenção nutricional precoce e melhor alocação de recursos. Diferentes métodos são apresentados na literatura para esta finalidade: Malnutrition Screening Tool, Short Nutritional Assessment Questionnaire, Nutritional Risk Index, Nutrition Risk Score, Nutritional Risk Screening, Mini Nutritional Assessment, Malnutrition Universal Screening Tool, Nutritional Screening Tool, Nutritional Screening Equation. No entanto, o emprego de muitos destes instrumentos está limitado pela inadequada metodologia empregada na derivação e/ou validação, pela seleção de grupos específicos de pacientes, pela pouca praticidade ou por necessidade de um especialista para seu emprego. Na ausência de um padrão de referência para emitir o diagnóstico nutricional, desfechos clínicos relevantes devem balizar a derivação e a validação de novos instrumentos. Este trabalho descreve os instrumentos de triagem nutricional acima referidos e apresenta considerações quanto ao seu emprego para adultos hospitalizados não selecionados. Termos de indexação:Avaliação nutricional. Desnutrição. Epidemiologia nutricional. Métodos epidemiológicos. Triagem.
