The decision making process at hospitals is based on its complexity level instead of the actual patient status. There are no universal and reproducible scores that allow clinicians to stratify each patient according to its status and risk of mortality and therefore allow them to take decisions. At Hospital Universitario Mayor we have designed an score, based on PSI/PORT score, to stratify our patients. Matherials and Methods: A retrospective cohort study was designed aplying the adapted PORT score to two groups of surgical patients, discharged alive and dead respectively. The asociation of each variable with dead risk was evaluated using chi square and logistic regretion methods. Sensititivity and specificity of the score were also analyzed and the correlation index was noted. Results: Modified PORT score has a high correlation with the risk of death in surgical patients in our study. However, this correlation is lower than the correlation found in a previous study in nonsurgical patients. Discussion: Surgical patients can be stratified according to the modified PORT score. We recomend to apply the score to a bigger group of patients with surgical and non-surgical pathologies and to include a variable evaluating the time of onset of the disease in the score.
