INTRODUCTION:
Nutrition assessment of critically ill patients is challenging but it should be part of the clinical nutrition routine in the hospital setting. OBJECTIVE:
To assess the nutritional risk and prognosis of patients admitted to the intensive care unit (ICU) of a University Hospital in Natal, Brazil. METHODS:
Cross-sectional study developed with adult and elderly patients between February 2017 and February 2020. The nutritional risk was detected by the modified Nutrition Risk in Critically Ill score (mNUTRIC score). The nutritional prognosis was assessed using the phase angle (PA), calculated from the resistance and reactance values provided by bioimpedance. Mann-Whitney test was used to verify the association of mNUTRIC-score and PA with the outcome (hospital discharge or death). Spearman’s correlation coefficient was used to verify the correlation between mNUTRIC-score and PA. RESULTS:
A total of 55 patients were included in this study. The average value of the NUTRIC score and PA was 3.13 ± 2.35 and 4.19 ± 1.21, respectively. Most patients had low nutritional risk. Among them, 81.8% were discharged and 18.2% died. Both mNUTRIC-score (p≤0.0001) and PA (p=0.04) were associated with the clinical outcome. These two parameters were negatively correlated (r=-0.3804; p=0.0059). CONCLUSION:
Most of the patients had a low nutritional risk determined by the mNUTRIC-score. Those with high nutritional risk had a worse outcome (death). A negative correlation was observed between the mNUTRIC score and the PA, showing that the higher the nutritional risk, the worse prognosis was found in critically ill patients.
INTRODUÇÃO:
A avaliação do estado nutricional de pacientes críticos é um desafio, mas faz parte da rotina da nutrição clínica hospitalar. OBJETIVO:
Avaliar o risco e o prognóstico nutricional, e suas relações, em pacientes críticos admitidos na unidade de terapia intensiva (UTI) de um hospital universitário em Natal, Brasil. MÉTODOS:
Estudo transversal, desenvolvido com pacientes adultos e idosos entre fevereiro de 2017 e fevereiro de 2020. O risco nutricional foi detectado pelo Nutrition Risk in Critically ill score modificado (mNUTRIC-score). O prognóstico nutricional foi avaliado mediante o ângulo de fase (AF). O teste de Mann-Whitney foi usado para verificar a associação do mNUTRIC-score e do AF com os desfechos (alta da UTI ou óbito). A correlação de Spearman foi usada para verificar a correlação entre o mNUTRIC-score e o AF. RESULTADOS:
Ao total, 55 indivíduos foram incluídos no estudo. O valor médio do mNUTRIC-score foi de 3,13 ± 2,35 e do AF foi de 4,19 ± 1,21. A maioria dos pacientes apresentaram baixo risco nutricional (76,4%) e tiveram alta da UTI (81,8%). Tanto o mNUTRIC-score (p<0,0001) como o AF (p=0,04) estiveram associados com o desfecho clínico. Esses dois parâmetros se correlacionaram negativamente (r= -0,3804; p=0,0059). CONCLUSÃO:
A maioria dos pacientes críticos estudados apresentaram baixo risco nutricional determinado pelo mNUTRIC-score. Aqueles com alto risco nutricional tiveram pior desfecho (óbito). Observou-se correlação negativa entre o mNUTRIC-score e o AF, demostrando que quanto maior o risco nutricional, pior o prognóstico clínico e nutricional em pacientes críticos.
