Teacher: Now, understand the problem? Solve this instance: Question: Does transthoracic echocardiography improve prediction of outcome over APACHE II in medical-surgical intensive care?
Answer: Statistical models utilizing clinical variables are predictive of mortality in MSICU. Models that include diagnostic transthoracic echocardiography variables do not provide incremental value to predict ICU mortality. These findings may have implications for non-invasive hemodynamic assessment of critically ill patients, and raise the hypothesis that echocardiography-guided interventions may not alter outcome in ICU.
