Multicenter Study Clinical Trial Controlled Clinical TrialAcute physiology and chronic health evaluation (APACHE II) and Glasgow coma scores as predictors of outcome from intensive care after cardiac arrest.
a) To examine the accuracy of the Acute Physiology and Chronic Health Evaluation (APACHE II) and the Glasgow Coma Scores as predictors of the outcome of patients following resuscitation from cardiac arrest; b) to study the impact of the components of APACHE II on the prediction. ⋯ The APACHE II scoring system cannot be recommended as a prognostic tool to support clinical judgement in cardiac arrest patients, but by modifying it, a more accurate prediction of poor outcome could be achieved. The Glasgow Coma Score explained to a great extent the predictive power of the APACHE II.

Critical care patients become confused in the intensive care setting. Several dangers exist in acute confusional states. Confused patients jeopardize their own safety, are more likely to die than nonconfused patients and are more likely to become cognitively impaired and require institutionalization. This article reviews the literature about patients experiencing acute confusional states in the critical care setting including intensive care unit (ICU) psychosis, postcardiotomy delirium and confusion in the elderly.

To evaluate the effects of "ego bias" on physicians' prognostic judgments. Ego bias is defined as systematic overestimation of the prognosis of one's own patients compared with the expected outcome of a population of similar patients. ⋯ The critical care attending physicians exhibited reverse ego bias that was mainly a function of their optimism about the overall survival rate for critically ill patients. The house officers exhibited ego bias that was mainly a function of their pessimism about the overall survival rate for critically ill patients.
