Objective : To study the outcome of inpatient trauma cases of Accident and Emergency Unit, Department of Surgery, Faculty of Medicine, Khonkaen university compared with the result of Khon Kaen Hospital and standard outcome.
Method : We retrospectively studied trauma patients who was admitted in Accident and Emergency Unit, Department of Surgery, Faculty of Medicine, Khon Kaen university between 1 January 1997 to 31 December 1997. TRISS score has been calculated to define the survival probability (Ps) of all 291 patients and stratified into 3 groups. We compared the actual death of each group to the outcome study of Khon Kaen Hospital (n=2492). We also used Z-statistic to compared the actual survivors and expected survivors from TRISS norms.
Result : The actual death of Non-preventable death group, Potentially preventable death group and Preventable death group were 41.67%, 45.45% and 6.39% respectively. The outcome study of Khon Kaen Hospital in each group were 87.6%, 67.7% and 2.8% respectively.
The Z-score was – 0.02306 (P = 0.008 – 0.01)
Conclusion : In Non-preventable death group (Ps 0.00-0.25), the outcome of treatment was better than the outcome study of Khon Kaen Hospital
In Potentially preventable death group (Ps 0.25-0.50), no statistically difference between the 2 studies
In preventable death group (Ps 0.50-1.00), the outcome study of Khon Kaen Hospital was better than outcome of Accident and Emergency Unit
The Z-score -0.02306 indicated no statistically difference between number of actual survivors and expected survivors from TRISS norms.
