Nutritional assessment is essential to set up proper nutritional support plans in TPN(total parenteral nutrition) consultation service. The objectives of this study are to develop the SNUH(Seoul National University Hospital) assessment tool that evaluates nutritional status by assessing and scoring the severity of three objective parameters - visceral proteins(albumin or prealbumin), body mass index and weight change - and to prove the validity of the SNUH assessment tool by comparing with the PG-SGA(Patient-Generated Subjective Global Assessment). The subjects of this study are 31 adult patients who were admitted to SNUH from June to October 2009 and asked for TPN consultation. Nutritional assessment was performed by using both the SNUH nutritional assessment tool and the PG-SGA. Spearman’s rank correlation coefficient was used to evaluate statistical significance. The result of nutritional assessment by the SNUH nutritional assessment tool shows that one patient is well nourished, nine are mildly malnourished,ten are moderately malnourished, and eleven are severely malnourished; two patients are in stage A(well-nourished), fifteen are in stage B(moderately malnourished or suspected malnutrition), and fourteen are in stage C(severely malnourished) according to the PG-SGA. The Spearman’s rho correlation coefficient is 0.852, therefore there is statistical significance between two assessment tools(p<0.01). Proper nutritional assessment is available by using the SNUH nutritional assessment tool which is simple and convenient to use. Also, the results are not different among assessors, since it uses objective parameters unlike the PG-SGA. It is expected to shorten working hours and standardize TPN consultation service through coherent nutritional assessment.
Abstract
Nutritional assessment is essential to set up proper nutritional support plans in TPN(total parenteral nutrition) consultation service. The objectives of this study are to develop the SNUH(Seoul National University Hospital) assessment tool that evaluates nutritional status by assessing and scoring the severity of three objective parameters - visceral proteins(albumin or prealbumin), body mass index and weight change - and to prove the validity of the SNUH assessment tool by comparing with the PG-SGA(Patient-Generated Subjective Global Assessment). The subjects of this study are 31 adult patients who were admitted to SNUH from June to October 2009 and asked for TPN consultation. Nutritional assessment was performed by using both the SNUH nutritional assessment tool and the PG-SGA. Spearman’s rank correlation coefficient was used to evaluate statistical significance. The result of nutritional assessment by the SNUH nutritional assessment tool shows that one patient is well nourished, nine are mildly malnourished,ten are moderately malnourished, and eleven are severely malnourished; two patients are in stage A(well-nourished), fifteen are in stage B(moderately malnourished or suspected malnutrition), and fourteen are in stage C(severely malnourished) according to the PG-SGA. The Spearman’s rho correlation coefficient is 0.852, therefore there is statistical significance between two assessment tools(p<0.01). Proper nutritional assessment is available by using the SNUH nutritional assessment tool which is simple and convenient to use. Also, the results are not different among assessors, since it uses objective parameters unlike the PG-SGA. It is expected to shorten working hours and standardize TPN consultation service through coherent nutritional assessment.
