Social Frailty Index: Development and validation of an index of social attributes predictive of mortality in older adults.

ABSTRACT: While social characteristics are well-known predictors of mortality, prediction models rely almost exclusively on demographics, medical comorbidities, and function. Lacking an efficient way to summarize the prognostic impact of social factor, many studies exclude social factors altogether.
