The trauma is the leading cause of death in the first four decades of life, but, in Korea, the trauma system and emergency medical services system are not develped well. because the outcome of severely injured patients often depends on the
severity
of
truma and quality of trauma care, the verification of the institutional capability to care for trauma patients according to the "optimal care" guideline has been a natural sequel. And the quality assurance for evaluating outcome of trauma care is
need
to develop or upgrade trauma care furthermore.
The present study is an prospective evaluation of trauma outcome and quality assurance of our hospital by use of TRISS and Z statics. logistic function norms related TRISS values to patient's survival probability (Ps). 155 patients, who were
segverely
injured by blunt trauma (ISS≥16) and older than 15 years old, were analyzed. Among them, 38 patients (24.5%) were died. Ps of survivals was 0.9152 amd deaths was 0.2501. Z static of deaths was -0.0494. Unpredicted deaths, who were died inspite
of
Ps≥0.5, were reviewed, and unapt trauma care was found in 4 cases.
By using both TRISS and Z statics, emergency physician will be more accurate in assessing the quality assurance of severely injured patients.
