Abstract

Objective: To compare results achieved in using the subjective global assessment (SGA) and the patient generated subjective global assessment (PG-SGA) in order to improve nutritional assistance to cancer patients. Materials and Methods: This is a transversal observational study with an analytical descriptive approach. The data collection was done through the application of SGA and PG-SGA in patients older than 20 years-old, both sexes, in a university hospital, with a cancer diagnosis. The study was approved by the Ethical Research Committee at PUCRS. Results: 68 patients took part of the study. The descriptive evaluation revealed 4 patients assessed as "well-nourished" by both SGA and PG-SGA. 96.5% of the 57 patients assessed by the SGA as "moderately or suspected of being malnourished" presented the same result in the PG-SGA. As regards the 7 patients appointed as "severely malnourished" by the SGA, 71.4% presented the same result in the PG-SGA. Such results disclosed a difference in the nutritional diagnosis of 4 patients, which is not statistically significant (p=0.135). Kappa’s quotient suggests a strong agreement between both methods (Kappa=0.793; p=0.001). Conclusion: Although the SGA is a common nutritional evaluation tool used in several hospitals, the use of the PG-SGA can also be an alternative, according to the availability and suitability of each place.
