Feasibility of preoperative patient self-assessed frailty: a single-centre pilot study
Authors' conclusion
We report that patients can complete a modified CFS achieving moderate agreement with the clinician's CFS assessment.
Study context
- Population
- Patients aged ≥65 yr attending preoperative assessment before major surgery, single centre, UKmedian age 74 yr
- Participants
- 80 patients
- Comparison
- Patient self-assessed modified Clinical Frailty Scale (CFS) vs clinician standard CFS
- Primary endpoint
- Feasibility of preoperative patient self-assessment of frailty using the modified CFS

Further findings
Agreement between patient self-assessment and clinician CFS assessment
- Overall agreement moderate (kappa coefficient)
- 0.433
- Self-assessments matching clinician assessment exactly or within 1 point
- 77%
- Agreement stronger treating CFS as 9-point scale and in participants aged ≤74 yr
- P<0.001 for kappa
- Post hoc subgroup analysis by age (≤74 yr vs >74 yr)
Direction of disagreement (patient vs clinician CFS)
- Patients tended to overestimate their frailty vs clinician (mean difference, CFS points)
- 0.263
- P=0.055
