| ABSTRACT |
|
Trauma is well known as a major cause of death and disability in Korea, but we do not have a optimal method to evaluate the trauma patients effectively.
The purpose of this study was to predict the prognosis and mortality of the trauma patients and to
evaluate the quality of trauma care by TRISS method.
A retrospective study of 100 cases of trauma victims who visited to emergency room and was admitted to surgical intensive care unit of Kyungpook University Hospital from January 1994 to December 1995 by TRISS method was made.
In this study, we have found out following results.
1. Sex ratio of male to female was 4 : 1 and the mean age was 44 years.
2. Analysis of injury mechanism showed high incidences of traffic accident(71%), fall down(14%), cultivator(5%), penetrating trauma(3%) in order of frequency.
3. A comparison between survivors and deaths showed difference in TS (14.81土1.31 vs.13.64 土1.43),
RTS (7.26土0.82 vs. 6.78土0.91), ISS( 29.94土10.24 VS. 37.45 土11.05), TRISS Ps-1 by TS and ISS(0.93
土0.11 vs. 0.79土0.15), and TRISS Ps-2 by RTS and ISS(0.89±0.15 vs. 0.73土0.19).
4. By TRISS method, unpredicted outcomes occurred in 11 of 100 with 10 unpredicted deaths and 1 unpredicted survivor by TRISS-1 and unpredicted outcomes occurred in 14 of 100 with 9 unpredicted deaths and 5 unpredicted survivors by TRISS-2.
5. The most common cause of death was chest trauma(36.4%).
6. The Z statics, quantitating the difference in the actual number of deaths and the predicted number of death, using TRISS-1 method was 0.84 and using TRISS-2 method was -0.57.
The authors conclude that the real dead patients exceeded the predicted outcome in TRISS-1 and the
real dead patients were less than the predicted outcome in TRISS-2, and our patient management as well as application of this method should be analyzed for accurate outcome.
In conclusion, TRISS method offers a good approach for predicting the prognosis and mortality of the trauma patient and evaluating trauma care.
