The clinical frailty scale, but not the FRAIL checklist is associated with mortality in old critically ill patients with COVID-19

Identifying frailty in critically ill patients can help to guide management, including the selection of appropriate interventions and the development of care plans such as time-limited trials in patients with an unclear benefit from critical care. The FRAIL checklist assesses five domains of frailty: functional impairment, recurrent hospitalizations, advanced malignancy and chronic diseases, irreversible organ failure, and long hospital stay. The CFS but not the FRAIL checklist was independently associated with mortality in old ICU patients. [...]we believe that in elderly ICU patients, CFS should be used to assess frailty because it also provides prognostic information.
