Determining the Frail-VIG index at
any given moment provides an approximate situational diagnosis
("at what point of their life trajectory is this person?").
Determining a sequence of different Frail-VIG index values serves to measure progress ("how is this person progressing?") and to monitor the outcome of interventions.
The Frail-VIG index offers excellent prognostic approximation (AUC of 0.9 after 12 months), thereby reducing the level of uncertainty among patients, relatives and professionals ("how close is this person to an end-of-life situation?").
The Frail-VIG index assists in adapting treatment intensity (by providing actions in accordance with patients' situation and preferences), advanced planning, and resource use optimisation based on healthcare objectives established by consensus among patients, relatives and professionals.
