Groningen Frailty Indicator
Also known as: GFI, Groningen Frailty Index, GFI frailty screen
The Groningen Frailty Indicator (GFI) is a brief 15-item self-report screening instrument that measures frailty across four domains: physical, cognitive, social, and psychological. Developed at the University of Groningen by Nardi Steverink, Joris Slaets, and colleagues around the turn of the millennium and characterized in Schuurmans and colleagues' 2004 study 'Old or Frail: What Tells Us More?', the GFI was designed to identify older people whose vulnerability is better captured by accumulated functional losses than by chronological age alone. Each domain contributes items scored so that the presence of a problem adds a point, producing a total of 0–15, with a score of 4 or higher commonly taken to indicate frailty. The GFI is widely used in Dutch and European primary care and oncology to flag older patients for fuller geriatric evaluation.
Key highlights
- Very brief (15 items) and self-administered, making it practical for routine primary care, oncology, and surgical screening.
- Covers four domains — physical, cognitive, social, psychological — capturing vulnerability that age or physical phenotypes alone would miss.
- Simple unweighted scoring with a clear cutoff (≥4) that clinicians can apply quickly at the point of care.
- Extensively validated and translated, with established predictive value for adverse outcomes in older adults.

When to use it
Use the GFI when you need a very short, self-report frailty screen for older adults that spans physical, cognitive, social, and psychological loss and can be administered without specialist equipment. It is widely used in primary care and in geriatric oncology and pre-operative assessment to decide which older patients should receive a comprehensive geriatric assessment. It suits busy clinical settings and surveys where brevity matters, and where chronological age is known to be a poor guide to risk. It is less appropriate as a stand-alone diagnostic, in populations whose cognitive impairment precludes reliable self-report (use an informant or performance measure), or when a detailed deficit-accumulation index or physical phenotype is specifically required.
Strengths & limitations
- Very brief (15 items) and self-administered, making it practical for routine primary care, oncology, and surgical screening.
- Covers four domains — physical, cognitive, social, psychological — capturing vulnerability that age or physical phenotypes alone would miss.
- Simple unweighted scoring with a clear cutoff (≥4) that clinicians can apply quickly at the point of care.
- Extensively validated and translated, with established predictive value for adverse outcomes in older adults.
- Self-report limits reliability in people with cognitive impairment unless an informant version is used.
- Equal weighting of heterogeneous deficits ignores their differing prognostic importance.
- Internal consistency is only moderate, reflecting the breadth of the construct rather than a single latent trait.
- The ≥4 cutoff is a screening compromise that may misclassify in populations unlike the original Dutch samples.

Frequently asked
How does the GFI compare with the Tilburg Frailty Indicator?
Both are short, self-report, multidomain frailty screens developed in the Netherlands, and they overlap substantially. The GFI is slightly older and organizes 15 items across physical, cognitive, social, and psychological domains with a frailty cutoff of 4. The TFI also has 15 frailty items but groups them into physical, psychological, and social domains, adds a separate determinants section, and uses a cutoff of 5. They identify overlapping but not identical frail groups; choice between them often comes down to setting and whether the explicit determinants block of the TFI is wanted.
What score indicates frailty on the GFI?
The total score runs from 0 to 15, and a score of 4 or higher is the conventional threshold for classifying an older person as frail. This cutoff is used to flag patients for comprehensive geriatric assessment or closer monitoring, such as before cancer treatment or surgery. It is a screening compromise between sensitivity and specificity and should prompt further evaluation rather than serve as a final diagnosis.
Why measure frailty instead of just using age?
Because age is a weak proxy for vulnerability: people of the same age differ enormously in functional reserve. Schuurmans and colleagues' study 'Old or Frail: What Tells Us More?' showed that a frailty score derived from accumulated losses predicts adverse outcomes better than chronological age. The GFI captures this by counting deficits across body, mind, social life, and mood, giving clinicians a direct, individualized estimate of risk that age alone cannot provide.
