Social isolation: an attributing factor of increased frailty risk and mortality amongst advanced-age intensive care unit survivors

Context Social isolation has been recognised as a significant attributing factor of allcause mortality. 2 More so among the older and homebound population. This study investigated the association between social isolation and disability burden and mortality rate of the older intensive care unit (ICU) survivors. The findings revealed that a onepoint increase in the isolation score was responsible for a 7% greater disability count and a 14% increase in 1year mortality risk. These findings indicated the significant negative impact on an older person’s health and were apt in providing insights to the unavoidable isolation measures demanded in the COVID19 pandemic.
