[Study on the occurrence of adverse health events in nursing homes : contributions from the Liège SENIOR cohort].

The SENIOR study followed a cohort of older people living in nursing homes for 8 years and examined their adverse health events. The results were analysed after 1, 3 and 8 years to identify predictive factors and improve care. After 1 year, residents with poorer motor and muscle function had a higher incidence of adverse health events such as death and falls. Sarcopenia predicted mortality, while poor physical performance was associated with falls. At 3 years, poor nutritional status and poor balance were important predictors of mortality, falls and loss of independence. At 8 years, younger age, higher body mass index, and good physical and cognitive performance were associated with longer survival. The study also examined the impact of the COVID-19 pandemic in nursing homes and found no significant association between frailty, nutrition, muscle strength and COVID-19. In conclusion, functional capacity and nutrition play a crucial role in predicting adverse events in nursing home residents. The results will guide public health policies and clinical interventions to improve quality of life.
