CALLEJA FERNANDEZ, Alicia et al. Food intake and nutritional status influence outcomes in hospitalized hematology-oncology patients. Nutr. Hosp. [online]. 2015, vol.31, n.6, pp.2598-2605. ISSN 1699-5198.

Background: malnutrition in oncology and hematology- oncology patients is important due to its prevalence and associated mortality and morbidity. The aims of the study were to assess the prevalence of malnutrition in oncology and hematology patients and determine if intake or malnutrition influences hospitalization outcomes. Methodology: a cohort study was performed in all patients admitted to the oncology and hematology wards in a 30-day period. Nutritional assessment was performed within 24-hours of admission and repeated after 7 days of hospitalization, including Subjective Global Assessment, anthropometry, dietary assessment (24-hour recall) and estimation of caloric and protein needs. Medical records were reviewed 30 days after discharge. Results: seventy-three patients were evaluated on admission and 29 on day 7 of hospitalization. The prevalence of malnutrition was 47.7%. On admission, patients consumed 71.6 (SD 22.0)% of the prescribed dietary calories and 68.2 (SD 23.5)% of prescribed proteins. The death rate was 2.8% among patients who ate ≥75% and 17.9% among those who ate <75% (p = 0.040). No significant differences were observed between the intake of calories (p = 0.124) and protein (p = 0.126) on admission and on day 7 of hospitalization. Nutritional status was related to readmission rate, being 35.1% for malnourished vs. 8% for well-nourished (p = 0.014). Nutritional status and food intake were not related to the rest of the studied outcomes (length of stay and mechanical, metabolic or infectious complications). Conclusions: intake did not decrease during hospitalization. There was an upward trend between reduced intake and mortality. Malnutrition was related to hospital readmission.
