Multidimensional prognostic models of surgical mortality

The multidimensional prognostic models of surgical mortality act as a prognostic alarm from the stratification of the mortality risk, with refinement of the clinical method at the prognostic level by optimizing the preoperative care with the use of novel statistical techniques based on the combination of logistic regression with the decision tree and Cramer's V oriented in positive sign by Phi. They are an alternative of integration of the surgical risk of the patient, anesthesia and surgery.
