Nutrition in the elderly hospital patient Nottingham studies.

Forty percent of elderly hospital admissions in the UK are undernourished, half severely so. Most continue to lose weight in hospital. not only because of disease, but also because of failure to identify and treat malnutrition and due to shortcomings in hospital food provision, upon which most patients depend for their nutritional care. Our studies have shown that more than 40% of food set before patients is left, and therefore wasted. This means that elderly patients are taking less than 70% of their energy (30-35 kcal/kg/day), and protein (1 dram/kg/day) requirements. Catering strategies, such as provision of smaller volume, high energy and protein density meals with snacks and, if necessary, proprietary oral supplements, have been shown not only to improve nutritional status of patients, but to result in improved clinical outcome. Our work has shown a relationship between malnutrition and loss of thermoregulation, which is reversed by appropriate feeding. We have also described the beneficial effects of overnight nasogastric tube feeding in undernourished patients with fractured femur. Like others, we have used a percutaneous endoscopic gastrostomy in the management of elderly patients with cerebrovascular and motor neurone disease, and have published audits of outcome in this field.
