Abstract
Background
The prevalence of malnutrition in hospitalized elderly patients (HEP) is high.
Objective
To investigate the behavior of several nutritional indicators and predictors of unfavorable clinical outcome.
Methods
Retrospective study with hospitalized elderly patients (N = 322). Nutritional instruments, indicators and outcome were investigated. Chi-square, Fisher and Mann–Whitney tests and univariate and multiple logistic regression analysis were used.
Results
The variables that, jointly, were associated with hospital stay longer than 7 days, include: the presence of complications (p = 0.0328; OR 1.946; IC95% 1.056; 3.585) and nutritional risk according to the NRS-2002 (p = 0.0016; OR 2.080; IC95% 1.322; 3.275). The variable that remained associated with complications in the multiple model was the nutritional risk according to the NRS-2002 (p = 0.0018; OR 2.587; IC95% 1.423; 4.703).
Conclusion
Nutritional risk using the NRS-2002 is a predictor of clinical outcome in hospitalized elderly patients.
