Prevalence of malnutrition among older people in medical and surgical wards in hospital and quality of nutritional care: A multicenter, cross-sectional study.

Abstract

To determine and compare the prevalence of malnutrition in medical and surgical hospital units; to assess quality of nutritional care and patients' perception about quality of food and nutritional care. Hospital malnutrition in older people leads to increased mortality, length of stay, risk of infections and pressure ulcers. Several studies show that malnutrition is often caused by hospitalisation and related to poor nutritional care. Few studies report data on surgical older patients. A cross-sectional, multicenter study was conducted in 12 hospitals in northern Italy. Malnutrition prevalence was determined according to the Mini Nutritional Assessment full-version. Head nurses were interviewed in 80 units, through a validated questionnaire regarding quality of nutritional care. Semi-structured interviews were administered to a sample of patients, to investigate their perception about quality of food and nutritional care. Two hundred twenty-eight patients of 1,066 were malnourished (21.4%). Medical patients were at higher risk, so were women, patients aged 85 or more, with impaired autonomy, pressure ulcers or taking more than three drugs. The lack of personnel impacts on quality of care: in 55% of the units, no nutritional screening is performed; nutritional history is investigated in 48% only. No protocols for nutritional problems exist in 70% of the wards; hardly ever the intake is measured. Patients are mostly satisfied, even though they report that food has no taste and is not well presented. They remark the need for more personnel. Prevalence was high, as found in other studies. Medical patients were at higher risk. Nutritional care was inadequate, and often no measures were adopted to prevent malnutrition. Staffing should be increased during meals. These findings will provide indications on the strategies needed to overcome such barriers.
