Assess patients for risk of malnutrition using health screening questionnaires and assessment tools for elderly. Through the screening results, we can help elderly improve their nutritional intake in areas where they are deficient, and help prevent and manage chronic diseases. Factors such as decreased physical function, reduced appetite, illness, and swallowing difficulties among the elderly can lead to a sharp decline in their food and nutrient intake. Malnutrition in the long-term will affect the elderly’s disease management, energy level, immunity, and mobility. Therefore, it is critically important to conduct regular nutritional health screenings to prevent malnutrition.
