Hospital malnutrition: incidence and prospective evaluation of general medical patients during hospitalization.

Abstract

The incidence of malnutrition and the effect of hospitalization was evaluated in 100 consecutive admissions to the Clinical Pathology R Department of the University of Genoa. Nutritional deficiencies were evaluated at the time of admission and discharge from the Hospital, among patients hospitalized 2 weeks or longer, using the following nutrition-related parameters: body fat, muscle proteins, weigh, rate of weight loss plasma proteins level, vitamin B12 and folic acid plasma level, plasma iron and ferritin. We also considered the nutritional alterations in malnourished patients with relation to appetite decrease and to pathological status. At the admission to the hospital, the findings showed a high incidence (79%) of alterations in some nutritional parameters. In patients with nutritional impairments we observed a worsening of most of the nutritional parameters during hospitalization, especially in patients with severe appetite decrease and those affected by sepsis, neoplastic, gastric and renal diseases.
