| Summary: | 碩士 === 亞洲大學 === 健康產業管理學系長期照護組 在職專班 === 98 === Objective - The objective of this study was to determine the ability of the long-form (LF) and short-form (SF) of the MNA (Mini-Nutritional Assessment) Taiwan versions (T1 & T2) and the MUST (Malnutrition Universal Screening Tool) versions in assessing the nutritional status of patients on hemodialysis (HD) in Taiwan.
Methods - Subjects of this study were 152 hemodialysis out-patients (78 men and 74 women) of a teaching hospital in Central Taiwan. The study included a structured questionnaire interview, anthropometric measurements and biochemical tests. The questionnaire included questions to elicit personal data and answers to the MNA, the MUST and the SGA (Subjective Global Assessment) scales. Results were analyzed wtih SPSS/Window12.0 Statistical software. Friedman Test and Wilcoxon Signed-Rank Test were used to determine the significance of results.
Results - The two MNA-LF versions (T1 and T2) rated 40.8% and 36.2% of subjects malnourished or at risk of malnutrition, resspepctively; the two MNA-SF versions rated 32.2% and 24.3% at risk of malnutrition; the two MUST versions rated 20.3% and 18.4%, respectively whereas the SGA rated 47.4%. Using results rated with the SGA as the reference, the two MNA-LF versions had kappa =0.734 and 0.666, repectively; the two MNA-SF versions, 0.450 and 0.446; and the two MUST versions, 0.172 and 0.265, respectively. When serum albumin was the reference, the two MNA-LF versions had kappa=0.450 and 0.479; the two MNA-SF versions, 0.267 and 0.356; the two MUST versions, 0.250 and 0.319 and the SGA, 0.414. When serum creatinine was the reference, the MNA-LF had kappa=0.389 and 0.380; the two MNA-SF versions, 0.306 and 0.2620; the two MUST versions, 0.088 and 0.179; and the SGA 0.462.
Conclusion - Results indicate that among the scales examined, both versions of the MNA-LF have the best ability in predicting the risk of malnutrion in Taiwanese patients on hemodialysis. The MNA-SF underrates the risk of malnutrition in these patients. Therefore, the MNA-SF should not be used for evaluating nutritional risk of patients on hemodialysis until the scale is further modified and validated.
