RESUMO

Objetivos:

Verificar a prevalência de risco nutricional em indivíduos hospitalizados e a concordância no diagnóstico nutricional através de cinco protocolos de triagem nutricional.

Métodos:

Um estudo transversal incluiu pacientes de ambos os gêneros, maiores de 18 anos, admitidos no hospital no período de janeiro a março de 2013. Dentro das primeiras 48 horas de internação, foram aplicados os seguintes protocolos de triagem nutricional Mini Nutrition Assessment (MNA); Mini Nutrition Assessment Short Form (MNA-SF); Subjective Global Assessment (ASG); Nutritional Risk Screening (NRS 2002); e Malnutrition Universal Screening Tool (MUST). Os protocolos são compostos de questões relacionadas à perda de peso, índice de massa corporal, capacidade funcional, inapetência alimentar e alterações gastrintestinais. Os indivíduos foram classificados em dois níveis bem nutridos e desnutridos.

Resultados:

Foi avaliada uma amostra de 100 pacientes, que evidenciou 49 (49%) indivíduos com risco nutricional pelo protocolo MNA; 53 (53%) pelo MNA-SF; 23 (23%) pelo MUST; 7 (7%) pelo NRS; e 4 (4%) pelo ASG. O gênero feminino e idades superiores a 60 anos prevaleceram na amostra. Três dos protocolos, MNA-SF, MUST e NRS, detectaram maior risco nutricional em pacientes com mais de 60 anos (p≤0,05). Observou-se que MNA e MNA-SF foram os protocolos que obtiveram melhor concordância (coeficiente Kappa=0,760, p<0,001).

Conclusões:

Houve boa concordância entre os protocolos de MNA e MNA-SF, porém não destes com os demais protocolos, que também não apresentaram concordância entre si. O protocolo que classificou a maior porcentagem de pacientes com risco nutricional foi o MNA-SF, e o que menos detectou risco nutricional foi o ASG...
ABSTRACT

AIMS:

To assess the prevalence of nutritional risk in hospitalized subjects and the agreement in nutritional diagnosis between five nutritional screening protocols.

METHODS:

A cross-sectional study included patients of both genders, aged 18, admitted to hospital from January to March 2013 Within the first 48 hours of admission, the following nutritional screening protocols were applied Mini Nutrition Assessment (MNA); Mini Nutrition Assessment Short Form (MNA-S); Subjective Global Assessment (ASG); Nutritional Risk Screening (NRS 2002); and Malnutrition Universal Screening Tool (MUST). The protocols consist of questions related to weight loss, body mass index, functional capacity, food appetite and gastrointestinal disturbances. Subjects were classified into two levels well-nourished and malnourished.

RESULTS:

A sample of 100 patients were evaluated, which showed 49 (49%) individuals at nutritional risk by the MNA protocol; 53 (53%) by MNA-SF; 23 (23%) by MUST; 7 (7%) by NRS; and 4 (4%) by ASG. The female and aged over 60 years prevailed in the sample. Three protocols, MNA-SF, MUST and NRS, showed a higher nutritional risk in patients over 60 years (p equal or less than 0.05). It was observed that MNA and MNA-SF protocols obtained better agreement (Kappa coefficient = 0.760, p less than 0.001).

CONCLUSIONS:

There was good agreement between the protocols MNA and MNA-SF, but not of those with other protocols, which also showed no correlation with each other. The protocol that ranked the highest percentage of patients at nutritional risk was the MNA-SF, and less nutritional risk was detected by ASG...
