Comparison of the different versions of the abbreviated injury scale in the assessment of isolated head trauma severity

Taiwan's trauma care benchmarks may be outdated. Updating the health insurance AIS is necessary. The health insurance versions AIS and AIS 2005 update 2008 were used to assess the severity of isolated head trauma among inpatients. The two versions resulted in significant differences in the AIS score and total ISS; in particular, the newer version resulted in a decrease in the trauma severity score. This study highlights the substantial differences in resource needs and outcomes when different AIS versions are used. Rigorous research is needed for any revision to meet public expectations for precision public health.
