Purpose: The current study was designed for development of a simplified malnutrition screening tool (SMST) for hospi-talized patients using readily available laboratory and patient information and for evaluation of its reliability compared to well-established tools, such as PGSGA and NRS-2002.
Methods: Anthropometric and biochemical measurements, as well as a few subjective assessments, of 903 patients who were preclassified by their nutritional status according to PGS-GA were analyzed. Among them, a combination of factors, including age, BMI, albumin, cholesterol, total protein, hema-tocrit, and changes in body weight and food intake, were statistically selected as variables for SMST.
Results: Accord-ing to SMST, 620 patients (68.7%) were classified as the normal group and 283 patients (31.3%) were classified as the malnutrition group. Significant differences in age, albumin, TLC, BMI, hemoglobin, hematocrit, total protein, cholesterol, and length of stay were observed between the two groups. For inter-methods reliability, the screening results by SMST were compared with those by PGSGA and NRS-2002. The comparison with PGSGA and NRS-2002 showed ‘Substantial agreement’ (sensitivity 94.4%, specificity 88.4%, κ = 0.747) and ‘Moderate agreement’ (sensitivity 96.1%, specificity 79.5%, κ = 0.505), respectively, indicating that SMST held high inter-methods reliability.
Conclusion: In conclusion, SMST, based on readily available laboratory and patient information and simple subjective assessments on changes in food intake and body weight, may be a useful alternative tool with a simple but reliable risk index, especially in resource-limited domestic hospitals.
