Introduction
There are no published results of differences in short- and long-term mortality of severely injured patients when they are categorized as polytrauma patients by different criteria. In this study, we evaluated the differences in mortality between different groups of severely injured patients.
Material and Methods
Helsinki Trauma Registry (HTR) was used for patient identification from 1.1.2006 to 31.12.2015. Penetrating trunk injuries and children <16 years are not included in the registry. The inclusion criteria for the HTR were ISS ≥16 in 2006 to 2011 and NISS ≥16 from 2012 onwards. Spinal injuries were excluded. Different groups were identified, and Kaplan-Meier survival curves were calculated to estimate the differences in mortality between different groups.
A total of 3359 trauma patients were included for the analyses.
In Kaplan-Meier analysis we see that Berlin polytrauma patients have significantly (Log Rank p<0.001) higher mortality in short-term (30 d to 1 year) compared to other groups but the difference in cumulative mortality gradually levels out compared to isolated injury patient group and in the end of the follow-up the difference turns other way around.
Conclusions
Berlin definition polytrauma patients had the highest NISS-scores, while all polytrauma patients had the second highest NISS-scores. However, patients in these groups were the young. Therefore, one might think that young patients have a capability to recover better from a severe trauma.
Polytrauma patients by Berlin definition have high short-term mortality compared to other severely injured patients. However, in long-term the mortality difference diminishes. Therefore, it is important to use all resources available in the early treatment of these patients.
