Tilburg Frailty Indicator

The standard validated threshold for TFI frailty is ≥5, so a score of 4 is technically below the standard threshold. However, a score of 4 should not be dismissed as clinically insignificant — it represents accumulation of frailty indicators that may be progressing toward threshold, and patients near threshold deserve monitoring. Review the domain breakdown: if 4 points are concentrated in a single domain (e.g., 4 of 4 psychological items positive), that domain warrants immediate targeted attention even if the total score does not reach the standard frailty threshold. Consider retesting in 3–6 months in patients near threshold.

Both TFI and VES-13 are validated multidomain community frailty screens, but they differ in structure and emphasis. TFI explicitly captures psychological (depression, anxiety) and social (isolation, support) dimensions that VES-13 does not assess — making TFI broader in scope. VES-13 is more focused on physical function difficulty and disability, with a validated weighting system that gives specific risk scores. VES-13 is more commonly used in oncology and US primary care settings; TFI is more commonly used in European community settings. Choice depends on the target population, available validation data, and whether psychological and social dimensions are a priority for the screening context.

Yes, and this is one of the TFI's key practical advantages. Patients with positive TFI social domain items — particularly those who live alone with limited social contact — can be directly and specifically referred to social work assessment and social prescribing services. The TFI social domain provides a standardized, documented basis for social care referral that is more objective than informal clinical impression alone. In integrated health and social care systems, a positive TFI social domain score can trigger automatic notification to the social care team for assessment, enabling parallel health and social care planning.

TFI is a self-report tool requiring patient comprehension of questionnaire items, and it is not appropriate for patients with moderate-to-severe dementia who cannot reliably self-report. Proxy completion by a knowledgeable caregiver is an acceptable alternative for cognitively impaired patients, though proxy reports for the psychological domain should be interpreted with caution as caregivers may underestimate psychological distress (particularly anxiety and cognitive complaints) in patients who have limited insight or express distress non-verbally. For patients with advanced dementia, tools designed for caregiver or clinician completion are more appropriate.
