Frailty status predicts futility of cardiopulmonary resuscitation in older adults.

Aim: To determine if frailty is associated with poor outcome following in-hospital cardiac arrest; to find if there is a "frailty threshold" beyond which cardiopulmonary resuscitation (CPR) becomes futile.

Methods: Retrospective review of patients aged over 60 years who received CPR between May 2017 and December 2018, in a tertiary referral hospital, which does not provide primary coronary revascularisation. Clinical Frailty Scale (CFS) and Charlson Comorbidity Index were retrospectively assigned.
