ABCElder functional-fit method
ABCElder uses four fit statuses: can use, can use with support, can use with adaptation, and strictly not suitable.
The method starts with mobility, memory, vision, dexterity, routines, support network, home setup, budget, location, and digital comfort.
The most important output is often the exclusion reason: travel burden, fall risk, setup burden, small text, fraud exposure, or missing caregiver support.
