ABSTRACT
ObjectiveTo evaluate the trauma care effect and the value of trauma and injury severity score (TRISS) in prediction of the mortality by using TRISS to calculate the survival probability of trauma patients in five hospitals from Zhejiang province in 2009.MethodsA retrospective study was done on trauma patients (study group) firstly admitted to Emergency Department of five hospitals from Zhejiang province in 2009.The relevant information was collected,including demographic data,trauma types and injury causes.The TRISS score was obtained through calculating injury severity score (ISS) and revised trauma score (RTS) on admission into emergency department.With the major trauma outcome study (MTOS) as control group,M value,standardized Ws value and 95% confidence interval (CI) were calculated to compare actual survival rate and anticipation survival rate.ResultsA total of 2 193 patients at mean age of 44.39 years were enrolled in the study,including 1 661 male patients (75.74%).Traffic accident injury was the most common,followed by fall injury.The mortality rate according to TRISS was 13.22%,but the actual mortality rate was 9.75%.For all the patients,M =0.80 indicated that the injury severity of the study group was significantly different from that of the control group.At the same time,Ws =2.15,95% CI for Ws1.54-2.77 showed that the actual survival rate of the study group was significantly higher than that of the control group.Besides,the survival rate of trauma patients in the affiliated hospitals and three hospitals at class A grade was significantly higher fian that of the control group,but there was no significant difference between three hospitals at class B grade and control group. ConclusionsTRISS overestimates the mortality of the study group,which is probably associated with the rapid development of traumatology and the old coefficients of TRISS.Setting up local trauma database and renewing coefficients of TRISS may improve the ability of TRISS in predicting mortality of the trauma patients.
