Authors' conclusion

In this large cohort of ICU patients admitted after a MET review, frailty was independently associated with higher one-year mortality, with outcomes worsening progressively with incrementing CFS. Our findings highlight the importance of incorporating frailty assessment into MET and ICU decision-making to guide individualised, goal-concordant care.

Study context

Population
Adult patients (≥16 years) admitted to ICU after a ward medical emergency team (MET) review between 1 January 2018 and 30 June 2022 with a documented Clinical Frailty Scale (CFS) scorepatients included
Participants
48,425 patients
Exposure
Frailty assessed categorically using the CFS 1-8, compared with CFS-1
Outcome
One-year mortality
Follow-up
One year

Main finding

As reported in the abstract

Adjusted attributable mortality risk

CFS-2 vs CFS-1
+5.6% (95% CI 2.8–8.4%)
CFS-8 vs CFS-1
+48.5% (95% CI 43.6–53.4%)

Observational data: associations, not effects.

Further findings

Baseline characteristics by frailty

Patients with higher frailty scores were older, more likely to have treatment limitations and a greater chronic disease burden
