  1. Protein-energy undernutrition among elderly hospitalized patients : A Prospective study.

    Article - En anglais

    Context Numerous studies have identified strong correlations between the severity of nutritional deficits and an increased risk of subsequent morbid events among the hospitalized elderly, but whether inadequate nutrient intake during hospitalization contributes to such nutritional deficits or the risk of adverse outcomes is not known.

    Objectives To identify the distribution of average daily nutrient intake among the nonterminally ill hospitalized elderly, ascertain what factors contribute to persistently low intakes, and determine whether the adequacy of nutrient intake correlates with the risk of mortality.

    Design Prospective cohort study conducted from 1994 to 1997.

    Setting University-affiliated Department of Veterans Affairs hospital.

    Patients A total of 497 patients 65 years or older (mean [SD] age, 74 [6] years ; 97% male ; 86% white) with a length of stay of 4 days or more.

    Main Outcome Measures Daily in-hospital nutrient intake, in-hospital mortality, and 90-day mortality.

    Results A total of 102 patients (21%) had an average daily in-hospital nutrient intake of less than 50% of their calculated maintenance energy requirements.

    Admission illness severity, average length of stay, and admission albumin and prealbumin levels for this low nutrient group did not differ significantly from those of the remaining patients.

    However, the low nutrient group had lower mean (SD) discharge serum total cholesterol (154 [44] mg/dL [4{1.1} mmol/L] vs 173 [42] mg/dL [4.5 {1. (...)
