Determining Energy Requirements in Hospitalised Older Adults 20 June 2021 / 15:00 - 15:30

Dr Elizabeth Weekes Speaker

In order to avoid the adverse impacts of under-and over-feeding in hospitalised older patients, especially those receiving artificial nutritional support such as tube feeding or parenteral nutrition, the estimation of nutritional requirements is a vital component of the dietitian's assessment.  While a number of international organisations recommend that energy expenditure is measured by indirect calorimetry in clinical practice, this is rarely practical or affordable, and dietitians are required to use one of a number of estimation methods e.g. factorial method, regression equations or the rule of thumb method (e.g. kcal/kg body weight).  Each method has its relevant strengths and weaknesses which will be discussed during this presentation.
