The goal of this interview is to gather a clinician's perspective on the feasibility and potential integration of a new Geriatric Functional Assessment System (GFAS) into their clinical practice.

Its goal is to collect and process data, apply machine learning, and enable clinicians to identify early signs of functional decline.
