Objective : To determine if pre‐complication nutrient intake can be predicted based on an admission assessment. Design : Survey (cross‐sectional study). Setting : Geriatric Rehabilitation Unit (GRU) of a Veterans Administration hospital. Patients : Three‐hundred‐twelve randomly selected admissions to the GRU. Measurements : At admission, each patient completed a comprehensive medical, neuropsychological, functional, and nutritional assessment. While remaining hospitalized, each subject was monitored on a daily basis for the development of complications. Complete calorie counts were obtained at least every other day, and the average pre‐complication daily volitional nutrient intake was expressed as a percent of predicted requirements as determined using the Harris‐Benedict equation. Results : Based on a stepwise linear regression analysis, the strongest predictor of pre‐complication volitional intake was the first day calorie count, followed by waist circumference, the percent of weight lost in the 6 months prior to admission, supra‐iliac skinfold thickness, and admission Katz ADL score. The model R 2 = 0.66. Conclusions : It is possible to predict pre‐complication nutrient intake with a fair degree of accuracy based on an admission assessment, which includes a 1‐day calorie count.
