Abstract:

Objective To establish a comprehensive nutritional assessment scale for hospitalized patients with objective and subjective nutritional assessment indicators. Methods The hierarchical structure model was established to evaluate the nutritional status of hospitalized patients by analytic hierarchy process, and the weight coefficients of various assessment indicators were worked out by Satty product method, then the comprehensive nutritional assessment scale for hospitalized patients was established. Results The newly established comprehensive nutritional assessment scale included 11 subjective and objective indicators, and the weight coefficients of indicators varied. The leading three important indicators for nutritional assessment were serum prealbumin (2.3), serum albumin (2.3) and degree of weight loss (1.6). Conclusion With both subjective and objective indicators, the new comprehensive nutritional assessment scale established with analytic hierarchy process transforms the qualitative indicator into the quantitative one. It is a new attempt to apply the mathematical theory into the area of clinical medicine.
