TRISS method 를 통한 복부외상환자의 예후 비교

Abstract

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 was any difference in outcome between patients treated at two hospitals. M e t h o d s: 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 scoring system between survivors and nonsurvivors in either hospital. W score was -0.182 in Hospital A and -9.700 in Hospital B. Z score was -0.193 in Hospital A and -2.011 in Hospital B. Misclassifications of predicted survival and death rates was 16.7% (Hospital A) and 18% (Hospital B) Conclusion: There was not statistic significance to the ATI, RTS, or ISS between survivors and nonsurvivors at either hospital. The TRISS methodology has some limitations for determining differences in outcomes of treatment at the two hospitals.
