[Frailty in nursing home : contribution of the SENIOR study]

Over the past 20 years, clinicians and researchers have shown increasing interest in frailty. However, there is still no consensus regarding its operational definition. An interesting definition in this context could be the one that best predicts functional decline and the occurrence of negative health outcomes. Moreover, frailty could be avoided, delayed and sometimes cured by the implementation of targeted interventions. The SENIOR cohort, a longitudinal study of nursing home residents, initiated in 2013, aims to contribute to the understanding of risk factors, consequences and dynamic of frailty. It also contributes to its management. This cohort is of great interest among scientists. Because of the large number of demographic, clinical and anamnestic data collected each year, the SENIOR study could fill the gap in the literature related to the frailty.
