Assessment of the nutritional status of surgical inpatients using two different screening tools

Methods of nutritional assessment and functional capacity in the identification of unfavorable clinical outcomes in hospitalized patients with cancer: a systematic review

CONTEXT

Malnutrition has a negative impact on patients with cancer. Identifying risk, nutritional status, and functional capacity can contribute to adequate and early nutritional therapy, which can reduce unfavorable clinical outcomes.

OBJECTIVE

To evaluate and summarize the main instruments of nutritional assessment and functional capacity and associate their results with clinical outcomes in hospitalized patients with cancer.

DATA SOURCES

A systematic search was performed in the PubMed/MEDLINE, Embase, SciELO, and LILACS databases. Studies in which researchers evaluated and compared screening, nutritional assessment, and functional capacity instruments and their associations with clinical outcomes were included.

DATA EXTRACTION

The data were extracted by 2 independent reviewers.

RESULTS

A total of 29 studies met the inclusion criteria (n = 20 441 individuals). The Nutritional Risk Screening-2002 (NRS-2002) and Patient-Generated Subjective Global Assessment (PG-SGA) were the most common tools used for nutritional assessment. High nutritional risk according to the NRS-2202 and worse nutritional status according to the PG-SGA and Subjective Global Assessment were positively associated with a longer hospital stay and mortality. Low functional capacity, according to handgrip strength, was associated with longer hospital stay and nutrition impact symptoms.

CONCLUSIONS

Tools such as the NRS-2002, PG-SGA, Subjective Global Assessment, and handgrip strength assessment are efficacious for assessing unfavorable clinical outcomes in hospitalized patients with cancer.
