1. Operationalizing a frailty index from a standardized comprehensive geriatric assessment

Abstract

A frailty index (FI) that is clinically sensible and practical for geriatricians is constructed and validated by basing it on a routinely used comprehensive geriatric assessment (CGA) instrument. The FI-CGA is a valid, reliable and sensible clinical measure of frailty that permits risk stratification of future adverse outcomes.

Abstract

The potential of an artificial neural network (ANN) in predicting survival in elderly Canadians, using self-report data, is evaluated in 8547 Canadians. An ANN provided more accurate survival classification than an unweighted frailty index suggesting that the concept of biological redundancy might be operationalized from health survey data.
