[Quality assurance in trauma surgery--what does the TRISS method offer ?].

The TRISS method offers a standard approach for evaluating the outcome of trauma care. Based on the data of more than 150,000 patients, TRISS offers a method of calculating the individual probability of survival of trauma patients. The calculation is based on anatomical, physiological data and the age of the patient. The basic scores for using TRISS are the Revised Trauma Score and the Injury Severity Score. Recent analyses demonstrate for blunt trauma patients a sensitivity of 60.9% and a specificity of 99.2%. What does TRISS offer in comparison to other trauma scores? TRISS offers a valid approach for the screening of trauma patients regarding unexpected survival/death. Based on the largest database of trauma patients, TRISS represents a method of maintaining quality assurance for prehospital and hospital trauma patient care; it also allows comparison with international standards of trauma care.
