Persistent Inflammation, Immunosuppression and Catabolism Syndrome (PICS): A New Horizon for Surgical Critical Care and Induced Frailty

"A frailty index will be determined as a combination of factors.~An older adult is considered physically vulnerable when they experience:~1. muscle weakness~2. fatigue~3. low physical activity, and unintentional loss in body weight, which has been agreed upon by a consensus of experts.~This will be collected at baseline, 3, 6 and 12 months."

A questionnaire used to assess physical activity will be administered at baseline, 3, 6 and 12 months.

A CT scan will occur as standard of care while the patient is hospitalized. Two additional CT scans will occur at 3 and 12 months to assess for sarcopenia.

Mobility monitors will be placed on the patients during the duration of their hospital stay. They will then where them at 3, 6 and 12 months for up to 10 days.
