The Prediction Value Of Injury Severity Score For Death Of The Acute Multiple Trauma Patients

Objective:Objective To investigate the prediction value of injury severity score (ISS) for death of the acute multiple trauma patients.Methods:The clinical data of patients who were in hospital during March2007to May2011were collected, and ISS scores and acute physiology and chronic education Ⅱ (APACHE Ⅱ) scores were assessed. ISS and APACHE Ⅱ’area under the receiver operating characteristic curve (AUC) and the best cut-off point were calculated, and their prediction index were calculated and compared.Results:The ISS’s and APACHE Ⅱ’s score in non-survivors were higher than the survivors. This difference had statistically significant difference(P<0.05). In prediction of death of the trauma patients, ISS scores≥20scores, sensitivity was76.7%, specificity was83.7%, agreement rate was82.7%and area under curve (AUC) was0.835. However for the APACHE Ⅱ, they were scores>17scores, sensitivity was80.5%, specificity was89.2%, agreement rate was88.0%and AUC was0.922. It is no statistically significant difference to compare determine value of ISS and APACHE Ⅱ in severe trauma patients (P>0.05)Conclusion:ISS is a useful index to predict the death of the acute multiple trauma patients. It is reasonable to defy severe trauma by ISS value greater than20score in multiple trauma patients. ISS is a standard method for evaluating severity of injury. It is simple and practical, therefore it should be recommended in clinical practice.
