Modulate the prevention stategy according to the level of frailty Prof Leocadio Rodríguez Mañas Hospital Universitario de Getafe
CONFLICT OF INTEREST DISCLOSURE I have no potential conflict of interest to report
Is it possible to assess the level of frailty? Is there different clinical phenotypes of frailty? Is there any evidence-based strategy to prevent frailty? Is it the prevention strategy the same in different settings?
Frailty as a dynamic functional state CARE FOCUSED ON Preventing frailty Preventing Disability Treating Frailty Preventing Disabilty Treating Functional Decline Preventing Dependency Treating Disability Managing Dependency Potential reversibility of functional decline Robust Frail Functional Limitation Disability Dependency Definition Interventions to improve quality and outcomes - and prevent or delay further functional decline What How Where?

IS IT POSSIBLE TO DESIGN SUCH A FLOWCHART FOR FRAILTY AT RISK YES NO SCREENING YES NO DIAGNOSIS YES NO PROGNOSIS TREATMENT
Is it necessary to modulate the prevention strategy according to the level of frailty? Yes How should it be modulated Clinical Phenotypes By severity By comorbidity By setting INTUITIVE NOT EVIDENCE-BASED GREAT OPPORTUNITIES FOR RESEARCH With which approaches Improving diet Physical exercise Managing cardiovascular risk Others OBSERVATIONAL STUDIES RCTS
