Incidence and recognition of malnutrition in hospital

Abstract

OBJECTIVES: To determine incidence of malnutrition among patients on admission to hospital, to monitor their changes in nutritional status during stay, and to determine awareness of nutrition in different clinical units. DESIGN: Prospective study of consecutive admissions. SETTING: Acute teaching hospital. SUBJECTS: 500 patients admitted to hospital: 100 each from general surgery, general medicine, respiratory medicine, orthopaedic surgery, and medicine for the elderly. MAIN OUTCOME MEASURES: Nutritional status of patients on admission and reassessment on discharge, review of case notes for information about nutritional status. RESULTS: On admission, 200 of the 500 patients were undernourished (body mass index less than 20) and 34% were overweight (body mass index > 25). The 112 patients reassessed on discharge had mean weight loss of 5.4%, with greatest weight loss in those initially most undernourished. But the 10 patients referred for nutritional support showed mean weight gain of 7.9%. Review of case notes revealed that, of the 200 undernourished patients, only 96 had any nutritional information documented. CONCLUSION: Malnutrition remains a largely unrecognised problem in hospital and highlights the need for education on clinical nutrition.
