Effects of Frailty, Sarcopenia and Muscle Wasting on Outcomes of Patients in the Surgical Intensive Care Unit

Critical Illness Clinical Trial

Official title:
Ultrasound Assessment of Muscle to Quantify Frailty.

Clinical Trial Summary

The primary aim of the study is to evaluate consequences of frailty in critically ill patients. We hypothesize that a higher frailty index (based on published questionnaires) predicts a longer surgical intensive care unit and hospital length of stay, less ventilator-free days and a higher likelihood of an adverse discharge disposition.

Our secondary aim is to identify muscle-size derived variables that can be used to predict frailty. We hypothesize that a low skeletal muscle mass measured by ultrasound can be used to quantify frailty, and to also predict the outcome of SICU patients, expressed as longer stay in the surgical intensive care unit and longer stay in the hospital, less ventilator-free days and a higher likelihood of an adverse discharge disposition.

Our third aim is to examine potential triggers of muscle wasting in critically ill patients. Muscle wasting will be assessed by repetitive ultrasound measurements of muscle mass. We hypothesize that a significant decrease in skeletal muscle mass predicts longer stay at the surgical intensive care unit and longer hospital length of stay, less ventilator-free days and adverse discharge disposition.

Clinical Trial Description

Frailty is defined as status of decreased physiological reserve which leads to a higher vulnerability to stressors. It is associated with a higher risk of morbidity and mortality. Within the geriatric population, frailty is common and a known predictor of adverse outcomes. The usefulness of a frailty assessment as an outcome measure in critically ill patients of all ages needs to be evaluated. This study evaluates whether frailty has an effect on outcome of critically ill patients.

Muscle weakness predicts outcome of ICU patients but is hard to determine in the ICU since the measurement is volition dependent. Muscle mass correlates with muscle weakness and can be assessed objectively. This study evaluates the consequences of reduced muscle mass or sarcopenia on the outcome of critically ill patients.

In addition, muscle wasting in the ICU may predict persistent functional disability. This study aims to examine muscle wasting of critically ill patients on the surgical ICU. ;
