[Simplified version of the therapeutic intervention scoring system and its prognostic value]

The study evaluates the competence of the "TISS-28" to distinguish inpatients at the ICU, between the ones likely to die from the ones likely to survive and to establish a threshold score for high likelihood to death. The findings obtained by the sample of 200 inpatients at 14 ICUs in Sao Paulo County showed that the TISS-28 presented association with mortality (p=0.0001). The cutting score established was 21. It was found that 80.88% of those who died had the TISS-28 score similar or higher and 68.18% of survivors had the score below 21. Furthermore, regarding to the prognostic value of TISS-28, it was showed up the accuracy of 0.72.
