Operationalizing Frailty Using the Frailty Phenotype and Deficit Accumulation Approaches

Olga Theou et al. Interdiscip Top Gerontol Geriatr. 2015.

Abstract

In both demographic and clinical studies, frailty is understood as a multidimensional state of increased vulnerability compared with the status of others of the same age. Of the many theoretical definitions of frailty, two are commonly employed: the physical frailty/phenotypic approach and the deficit accumulation approach. The purpose of this chapter is to discuss how frailty is conceptualized and operationalized based on these two approaches.
