Conclusions There is considerable variability in the type of measures utilized to measure physical impairments and limitations in survivors of critical illness .
Purpose To identify measures used to evaluate the broad constructs of functional impairment and limitations in the critically ill across the continuum of recovery , and to evaluate , synthesis e and compare the clinimetric properties of the measures identified .
The surgical intensive care unit optimal mobility score predicts mortality and length of stay*
Objectives : To test if the surgical intensive care unit optimal mobility score predicts mortality and intensive care unit and hospital length of stay . Design : Prospect i ve single-center cohort study . Setting : Surgical intensive care unit of the Massachusetts General Hospital . Patients : One hundred thirteen consecutive patients admitted to the surgical intensive care unit . Investigations : We tested the hypotheses that the surgical intensive care unit optimal mobility score independent of comorbidity index , Acute Physiology and Chronic Health Evaluation II , creatinine , hypotension , hypernatremia , acidosis , hypoxia , and hypercarbia predicts hospital mortality , surgical intensive care unit and total hospital length of stay . Measurements and Main Results : Two nurses independently predicted the patients ’ mobilization capacity by using the surgical intensive care unit optimal mobility score the morning after admission , whereas a third nurse recorded the achieved mobilization levels of patients at the end of the day . A multidisciplinary expert team measured patients ’ grip strength and assessed their predicted mobilization capacity independently . Multivariate analysis revealed that the surgical intensive care unit optimal mobility score was the only independent predictor of mortality . Surgical intensive care unit optimal mobility score , hypotension , and hypernatremia ( > 144 mmol/L ) independently predicted intensive care unit length of stay , whereas the surgical intensive care unit optimal mobility score and hypernatremia predicted total hospital length of stay . The Acute Physiology and Chronic Health Evaluation II score was not identified in the multivariate analysis . The surgical intensive care unit optimal mobility score  was also a reliable and valid instrument in predicting achieved mobilization levels of patients . Conclusions : In surgical critically ill patients presenting without preexisting impairment of functional mobility , the surgical intensive care unit optimal mobility score is a reliable and valid tool to predict mortality and intensive care unit and hospital length of stay .
