[Frailty Diagnosis in Different Settings].

Frailty Syndrome has been recognized in several settings as a major predictor of negative outcomes. A frailty diagnosis can have important consequences for clinical decision-making and provides the opportunity to implement preventive strategies.

Diagnostic tools must be based on the resources available and on their relevance for the particular setting. The current review offers insights on current models and the most successful diagnostic instruments used in the anesthesia, intensive care, emergency, and palliative settings.
