Food Intake in Older Patients

Nutritional Status in Hospitalised Geriatric Patients

Geriatrics, Nutritional Status, Hospitalisation

Unintentional weight loss and undernutrition are well described problems in elderly inpatients, occurring in around 23% to 62% of hospitalised elderly in developed countries. Not only are a large number of elderly patients undernourished at admission but a substantial proportion will lose weight and become malnourished during their hospital stay, putting them at increased risk of morbidity, mortality, poor clinical outcomes and prolonged length of hospital stay. However, as it is frequently impossible to correct undernutrition prior to hospital admission, every effort should be made to prevent weight loss and correct undernutrition during hospitalization. Therefore, screening and identification of predictors of patients at risk of weight loss and undernutrition at admission, and identification of modifiable factors (e.g. eating preferences and poor food hospital intake), where intervention might be helpful, are important aspects in the management of these patients. Before designing a food intervention study, there is a need to, firstly: 1. describe hospital food intake, eating habits and preferences in elderly inpatients during hospitalization 2. describe predictors of hospital food intake in elderly during hospitalisation 3. compare energy and protein intake in elderly inpatients during hospitalisation with the United Kingdom Dietary Reference Values (DRVs) This study is a hospital based observational study. Eligible participants will be 125 patients (aged ≥ 65 years old) admitted to the geriatric wards of 2 hospitals in the West of Scotland. Eligible participants will be seen 96 hours after admission in order to explain the study process and to obtain written consent. The researcher will record basic body size measurements and will ask the patient questions about living conditions, feelings, memory, health, eating habits, opinions about the hospital food service. Nursing staff will be asked about patient's functional activity. The researcher will also take pictures of a subset of patients' main meals (breakfast, lunch and dinner) on a single day, prior to and after eating. The researcher will meet each patient three times in total. The first time 4 days after admission; a second time, during the hospital stay and, finally, around the time of discharge to repeat some measurements including weight, BMI, skinfold, mid upper arm circumference, grip strength and calf circumference.
