Abstract

Objective

This study aimed to evaluate the association between the phase angle (PhA) and hospital-associated disability (HAD) in older patients admitted to an internal medicine ward.

Methods

This was a prospective observational study in a single acute care hospital. HAD was defined as a decrease of at least five points in the Barthel index at discharge compared to pre-admission. Multiple logistic regression analysis was used to determine the association between PhA and HAD. The cut-off point for PhA was evaluated using a receiver operating characteristic curve.

Results

This study included 215 patients (113 males; mean age: 80.8 years). The HAD incidence rate was 27.9 %. Multiple logistic regression analysis showed that PhA was associated with HAD (odds ratio: 3.47, 95 % confidence interval: 1.95–6.18, p < 0.001). The PhA cut-off points for predicting HAD were 3.7° for men and 3.6° for women.

Conclusion

PhA was associated with HAD in older patients admitted to the internal medicine ward and may be a useful indicator for predicting HAD.

一项前瞻性观察研究：内科病房住院患者相位角与医院相关残疾之间的关系

目的：本研究旨在评估住院内科病房老年患者的相位角（PhA）与医院相关性残疾（HAD）之间的关系。方法：这是一项在一家急症护理医院进行的前瞻性观察性研究。HAD被定义为出院时Barthel指数与入院前相比至少下降5个点。采用多元logistic回归分析确定PhA与HAD之间的关系。PhA的分界点采用受试者工作特性曲线进行评估。结果：本研究纳入215例患者(男性113例；平均年龄：80.8岁)。HAD的发病率为27.9%。多元logistic回归分析显示PhA与HAD相关（优势比：3.47,95%可信区间：1.95 ~ 6.18,p < 0.001）。预测HAD的PhA分界点男性为3.7°，女性为3.6°。结论：PhA与住院内科老年患者HAD相关，可作为预测HAD的有效指标。

期刊介绍： Clinical Nutrition ESPEN is an electronic-only journal and is an official publication of the European Society for Clinical Nutrition and Metabolism (ESPEN). Nutrition and nutritional care have gained wide clinical and scientific interest during the past decades. The increasing knowledge of metabolic disturbances and nutritional assessment in chronic and acute diseases has stimulated rapid advances in design, development and clinical application of nutritional support. The aims of ESPEN are to encourage the rapid diffusion of knowledge and its application in the field of clinical nutrition and metabolism. Published bimonthly, Clinical Nutrition ESPEN focuses on publishing articles on the relationship between nutrition and disease in the setting of basic science and clinical practice. Clinical Nutrition ESPEN is available to all members of ESPEN and to all subscribers of Clinical Nutrition.
