Malnutrition in the hospital setting

Australia’s ageing population has resulted in a continued rise of hospital admissions in the elderly1 leading to an increase in hospital acquired complications, such as malnutrition(nosocomial malnutrition). This malnutrition is a considerable problem particularly for the those over 65 years old2 whose treatment encompass a broad range of (often multifactorial) medical conditions3, e.g. dysphagia, intestinal resection, surgical and syndrome complications (such as cachexia and anorexia due to fasting or disease processes, loss of abilities due to stroke/dementia etc.) or psychosocial and environmental changes such as sleep deprivation, pain, and depression 3, 4. Up to 20-50% of all medical and surgical patients develop nosocomial malnutrition whilst admitted5, often going undiagnosed, with some studies suggesting up to 60% of undiagnosed patients are already at ‘high risk ‘ of malnutrition 5, 6. This is concerning as even short term deficits in nutrients and energy in hospital settings can have devastating outcomes clinically (and financially). Malnutrition radically affects the hyper-metabolic and hyper-catabolic patients, the function and recovery of their physiological systems, decreasing wound healing and increasing infection rates7, resulting in:
- Increased morbidity rate8
- Increased mortality rate (incidence of mortality of malnourished patients at 1 year being nearly 30% in 1 Australian study8)
- Delays in treatment (e.g.
