Purpose
The objective of this study was to develop a new nutrition screening tool for quality improvement of the nutritional care process in an acute care hospital with a 2,000-bed capacity.Methods: To evaluate the current nutrition screening tool, we first examined 435 patients (274 men, aged 59.0±12.2 years). In the second step, the nutritional status of 387 patients (215 men, aged 57.5±13.3 years) was assessed by the scored patient-generated subjective global assess-ment (PG-SGA) tool. Variables such as age, body mass index (BMI), plasma albumin concentration, weight change, food intake change, and disease severity were analyzed to select indices for developing a new Severance nutrition screening index (SNSI).Results: The current nutrition screening tool had a poor correlation with the PG-SGA (?=0.180, P<0.0001). The SNSI was calculated as follows: SNSI = 1.5×albumin+1.0×BMI+4.5×intake change+1.5×weight loss (for al-bumin<3.0, BMI<20, and decreased intake and weight loss>5% of usual body weight). The SNSI showed a sen-sitivity of 90.5%, a specificity of 90.7%, and a high corre-lation (?=0.628, P<0.0001) with the PG-SGA.Conclusion: The SNSI appears to be a valid and useful nutrition screening tool to determine the nutritional risk of patients in acute care hospitals.
