functional assessment staging tool
Also written as: FAST
Seven-stage system for measuring functional decline in dementia from normal aging through severe impairment.
Full Definition
The Functional Assessment Staging Tool (FAST) is a validated instrument used to assess and stage functional decline in dementia patients. The tool consists of seven stages ranging from normal adult functioning to severe dementia with loss of basic abilities. Each stage describes specific functional capabilities and deficits, allowing clinicians to track disease progression and make appropriate care planning decisions. The FAST scale is particularly useful for determining prognosis, planning interventions, and communicating with families about expected disease trajectory.
Usage
Usage note: Focuses specifically on functional abilities rather than cognitive testing.
