TRISS method 를 통한 복부외상환자의 예후 비교

초록

Purpose: Currently, trauma patients in Korea are treated in general hospitals instead of trauma centers. We performed this study to determine the prognosis for trauma patients through scoring systems and to identify whether there was any difference in outcome between patients treated at two hospitals. Methods: We retrospectively reviewed the medical records of abdominal trauma patients admitted to the ICU in two hospitals. Hospital A is located in Seoul (800 beds), and Hospital B is located in Kyungju (400 beds). There were 48 abdominal trauma patients in Hospital A from January 1, 1997, to December 31, 1998, and 50 patients in Hospital B from January 1, 1995, through December 31, 1998. The abdominal trauma index (ATI), revised trauma score (RTS), and injury severity score (ISS) of each patient were obtained. TRISS scores and W, Z statistics were then calculated. Results: There were no significant statistical differences in scoring systems between survivors and nonsurvivors in either hospital. The W score was -0.182 in Hospital A and -9.700 in Hospital B. The Z score was -0.193 in Hospital A and -2.011 in Hospital B. Misclassification rates of predicted survival and death were 16.7% in Hospital A and 18% in Hospital B. Conclusion: There was no statistical significance in ATI, RTS, or ISS between survivors and nonsurvivors at either hospital. The TRISS methodology has some limitations for determining differences in outcomes of treatment between the two hospitals.
