Two Prognostic Indices for the Trauma Patient.

摘要

A trauma index, called the CHOP index, based on serum creatinine, hematocrit, serum osmolality, and systolic blood pressure was evolved from retrospective and prospective studies of 700 patients from the Maryland Institute for Emergency Medicine. A decision rule which predicts death or survival resulted in a misclassification rate of less than 10% for patients in the trauma unit for more than one day. The CHOP index and a respiratory index were utilized in a retrospective study of 177 consecutive intubated patients. Prognosis regions were specified in the space determined by the two indices. A nomogram which allows one to follow the course of a patient with respiratory problems is described. These results have been applied to military and civilian medicine including trauma patient prognosis and monitoring, triage of mass casualties, objective method of evaluating care of critically ill patients, and comparison of therapeutic regimens.
