Frailty Before Critical Illness and Mortality for Elderly Medicare Beneficiaries.

ABSTRACT:

Objectives

To estimate the effect of pre-intensive care unit (ICU) health categories on mortality during and after critical illness, focusing specifically on the effect of pre-ICU frailty on short- and long-term mortality.

Design

Retrospective cohort study.

Setting

Medicare claims data from 2004 to 2008.

Participants

A nationally representative sample of elderly Medicare beneficiaries admitted to an ICU in 2005.

Measurements

Participants were classified into four pre-ICU health categories (robust, cancer, chronic organ failure, frailty) using claims data from the year before admission, allowing for assignment to multiple categories. The association between pre-ICU health category and hospital and 3-year mortality was assessed using multivariable logistic
