Functional Parameters of Nutrition
Functional assessment is at the heart of understanding how a chronic disease and its therapy impact on patients. It puts into tangible terms what the patient is capable of and brings an understandable ‘human context’ to the patient burden. Functional status can be a prognostic indicator. It may also have a role in treatment selection for individual patients and be used to enter and stratify patients in clinical trials. It remains to be seen whether it will be possible and practical to use end-points such as function (and other related end-points such as ‘quality of life’) to direct individual patient management. Using cancer cachexia as a paradigm, this chapter sets out to discuss some of the broader issues in functional patient assessment. New approaches to assessing function and preliminary experience with an emerging technology are also presented.
