Development and validation of a nutrition screening tool for hospitalized cancer patients

Abstract

Background & aims: Although various nutrition screening tools are used, they are not specific for the screening of malnourished cancer patients. The objective of this study was to develop a nutrition screening tool that could be used to identify cancer patients at risk for malnutrition.

Methods: Of 3010 cancer patients admitted to the National Cancer Center of Korea between April 1 and June 2, 2008, the nutritional status of 1057 patients was assessed by the Scored Patient-Generated Subjective Global Assessment (PG-SGA). Variables used in current nutrition screening tools were analyzed to select indices for a developing malnutrition screening tool for cancer patients (MSTC). The equation for the MSTC was established using receiver operating characteristics curves. Sensitivities and specificities of the MSTC were calculated using the PG-SGA as gold standard.

Results: The MSTC was calculated as follows: [MSTC = -0.116 + (1.777 × intake change) + (1.304 × Eastern Cooperative Oncology Group performance status) + (1.568 × weight loss) + (-0.187 × body mass index)]. The MSTC had a sensitivity of 94.0%, a specificity of 84.2%, and high agreement (κ = 0.70, P < 0.0001) with the PG-SGA.

Conclusions: The MSTC appears to be a valid nutrition screening tool for determining nutritional risk in hospitalized cancer patients.
