Multicenter Study Comparative StudyNutritional and hydration status in elderly subjects: clinical rating versus bioimpedance analysis.
Malnutrition and dehydration are common in elderly. A simple, reliable instrument to assess nutritional and hydration status would be very helpful. Bioelectrical impedance analysis (BIA) has been promising in this context, but data of elderly persons and geriatric in-hospital patients are rare. ⋯ We then compared BIA measurements with clinical judgement of hydration status in 103 acute geriatric hospital in-patients. Concordance between the results of clinical judgement and BIA measurements was only 43.7%. In assessing geriatric in-patients, there is little concordance between the clinical and the bioelectrical evaluation of the hydration status.
