On the interaction of disability and aging: Accelerated degradation models and their influence on projections of future care needs and costs for personal injury litigation.

Purpose: Accelerated degradation models are emerging as ways to characterize the interaction between disability and the functional decline of aging and to provide insights about the processes of aging with disability. Typically the models employ sophisticated mathematical treatments that are beyond the scope of many clinicians, lawyers, and others who might benefit from the information they contain. The purpose of this report is to characterize some rudimentary features of the models, in more readily understandable language, and illustrate how understanding of the underlying constructs can influence decisions regarding resource allocation and other projections of future care needs.
