---

Assessment tool for identifying falls risk in elderly patients admitted to hospital or other 24h healthcare institutions. This version of the tool is based on a modified Norwegian translation, which has been deployed by the The Norwegian Patient Safety Programme.

**Purpose.** For screening for falls risk in patients over 65 years of age, and other adults with neurological or cognitive conditions or significant visual impairment.
