Frailty assessment

Enter all five measures. SHARE-FI uses sex-specific equations and was developed for community-dwelling adults aged 50 years and older.

—DFS score
Sex-specific equation

Select the equation corresponding to the sex category used by the original SHARE-FI instrument.

In the last month, have you had too little energy to do the things you wanted to do?

Choose Yes if appetite has diminished (or the specified fallback response indicates eating less than usual).

Enter the highest of four consecutive measurements: two from each hand, measured with a hand dynamometer.

Because of a health problem lasting or expected to last more than 3 months, is there difficulty walking 100 metres or climbing one flight of stairs without resting?

How often do you do low- or moderate-energy activities, such as gardening, cleaning a car, or going for a walk?

The result will appear after all fields are completed. SHARE-FI is a screening instrument, not a standalone diagnosis.

About SHARE-FI

The Survey of Health, Ageing and Retirement in Europe Frailty Instrument (SHARE-FI) is a brief, sex-specific frailty screening tool developed for community-dwelling adults aged 50 years and older. It combines five measures reflecting exhaustion, appetite, handgrip strength, functional difficulty, and physical activity.

The published method calculates a predicted discrete-factor score (DFS) using a separate equation for female and male participants, then applies sex-specific thresholds to classify non-frail, pre-frail, or frail status.

How to interpret the result

  • Non-frail: lowest SHARE-FI frailty category.
  • Pre-frail: intermediate category; consider further assessment of modifiable contributors.
  • Frail: highest category; consider comprehensive clinical and functional assessment.

Important limitations

The original validation was based on community-dwelling European participants. The authors caution against applying SHARE-FI as a screening tool in hospital or residential-care populations. Local performance in Indonesian populations and specifically in cardiac patients has not been established by the cited derivation study.
