The association of clinical frailty with outcomes of patients reviewed by rapid response teams: an international prospective observational cohort study

Abstract

BACKGROUND: Frailty is a state of vulnerability to poor resolution of homeostasis after a stressor event and is strongly associated with adverse outcomes. Therefore, the assessment of frailty may be an essential part of evaluation in any healthcare encounter that might result in an escalation of care.
