The Mobility and Impact of Frailty in the Intensive Care Unit.

Prevalence of pre-existing frailty in patients admitted to the intensive care unit (ICU) is increasing. Critical illness leads to a catabolic state that further diminishes body reserves and contributes to frailty independent of age and prehospital functional status. Because early mobilization of patients in the ICU results in accelerated recovery and improvement in functional status and quality of life, frailty can severely affect the mobility of patients in ICU ultimately prolonging recovery. Understanding the concept of frailty and the association of frailty and its impact on mobility in the ICU, identifying patients, and timely resource allocation helps in optimum care and improves clinical outcomes.
