Abstract:

Objective: To evaluate the nutritional status of inpatients using modified patient-generated subjective global assessment (mPG-SGA), and to compare the correlation of evaluation between mPG-SGA and the standard patient-generated subjective global assessment (PG-SGA), and between mPG-SGA and the other indexes. Methods: The nutritional status of 258 patients with gastric and colon cancer at admission in Department of Surgery, Ruijin Hospital was evaluated by traditional single laboratory indexes including serum prealbumin, albumin in serum or hemoglobin, and human measurement indexes including body mass index, triceps skinfold, or arm muscle circumference, and PG-SGA, mPG-SGA. The correlations of evaluation results between mPG-SGA and each traditional single nutrition evaluation indexes and that between mPG-SGA and PG-SCA were compared. Results: The average time of evaluation using mPG-SGA (302.2±15.7) min was significantly less than that using PG-SGA (855.6±20.0) min. The incidence of malnutrition in the patients was 36.4% evaluated by mPG-SGA. The correlation of evaluative results was present significantly between mPG-SGA and PG-SGA and between mPG-SGA and each traditional single nutritional evaluation indexes (P<0.01). Conclusions: mPG-SGA could be a more convenient tool of nutritional assessment for Chinese cancer patients. Further studies will be needed for the patients with other malignant tumors.
