PRISMA-7 (frailty screen)
Seven-item frailty case-finding.
What it is for
Screening older adults for frailty. ≥ 3 "yes" suggests frailty — assess further.
Use the working calculator
The working PRISMA-7 (frailty screen) calculator is on our calculators page. It is free and needs no account. Enter the values and it shows the result with the reading that goes with it.
The calculators are free. The trial opens the protocols and pathways they link to.What you enter
The calculator asks for 7 items.
- Are you older than 85 years? (1 point)
- Male sex? (1 point)
- Health problems that limit your activities? (1 point)
- Do you need someone to help you regularly? (1 point)
- Health problems that make you stay at home? (1 point)
- If in need, can you count on someone close? (No = 1) (1 point)
- Do you regularly use a stick, walker or wheelchair? (1 point)
How the result is read
The result is shown as PRISMA-7, out of a maximum of 7.
The calculator reads each total as follows. Where a single answer changes the reading (for example sex, age or one extreme value), the working calculator says so.
| Total | Band | What the calculator says |
|---|---|---|
| 0 to 2 | Frailty less likely | Re-screen periodically. |
| 3 to 7 | Frailty likely | Comprehensive geriatric assessment; confirm with Clinical Frailty Scale / gait speed. ≥ 3 — sensitive for frailty. |
