title: [Prognostic models in severe head injury].
abstract: Severe head injury (SHI) is one of the most important health, social, and economic problems in industrialized countries. Most of the recent studies related to this entity still show pessimistic results, with percentages of mortality and unfavourable outcomes very similar than those reported in the last quarter of century. In order to make predictions for patients with SHI, different "prognostic formulas or models" reviewed in this manuscript, have been developed with the main objective of performing reliable predictions for patients with this pathology. These models are constructed by using a group of "prognostic indicators or factors" and different "prognostic scales" useful for measuring the final outcome. The different "statistical techniques or methods" necessary to develop these prognostic models are also analyzed in this paper.
