Geriatrics
Assess independence in six basic activities of daily living using the Katz Index. Scores range from 0 (dependent) to 6 (fully independent). Pair with [Morse Fall Scale](/tools/morse-fall-scale) for fall risk and [Timed Up and Go](/tools/get-up-and-go) for mobility.
Formula
Total score = sum of 6 items (each 0 or 1). Range 0-6. 6 = fully independent, 0 = fully dependent.
