Brief summary
In the surgical intensive care unit (SICU), goals of critical care are often discussed in long-term ventilated patients around the time of extubation. Muscle weakness predicts extubation failure but formal muscle strength assessment by the Medical Research Council scale is time-consuming and not part of the daily clinical exam. In this observational study, we hypothesize that COMA measurement, routinely used by the SICU nurses, is a reliable and valid predictor for patients' SICU outcomes. This prospective observational study is carried out within a consecutively enrolled cohort of adult patients who are extubated in two SICUs at Massachusetts General Hospital, Boston.

Other
| Measure | Time frame | Description |
|---|---|---|
| Validation: correlation between COMA and actual skeletal muscle index assessed by computer tomography | Within 72 hours after extubation | Skeletal muscle index is measured at the level of the 3rd lumbar vertebrae |
| Validation: Receiver operating curve (ROC) analysis - Acute Physiology and Chronic Health Evaluation II | At the day of admission to the ICU as well as within 72 hours after extubation | ROC curve of COMA compared to ROC curve of Acute Physiology and Chronic Health Evaluation (APACHE) II |
| Validation: Receiver operating curve (ROC) analysis - Charlson Comorbidity Index | At the day of admission to the ICU as well as within 72 hours after extubation | ROC curve of COMA compared to ROC curve of Charlson Comorbidity Index (CCI) |
| Validation: Receiver operating curve (ROC) analysis - Richmond Agitation and Sedation Score | Within 72 hours after extubation | ROC curve of COMA compared to ROC curve of Richmond Agitation and Sedation Score (RASS) |
| Validation: Receiver operating curve (ROC) analysis - Confusion Assessment Method ICU score | Within 72 hours after extubation | ROC curve of COMA compared to ROC curve of Confusion Assessment Method (CAM) ICU score |
| Validation: weighed kappa statistics | Within 72 hours after extubation | Inter-rater agreement with COMA score between A.M. and P.M. shift nurse |
