This prospective study assessed the efficacy of the predicting power for mortality of two different prehospital scoring systems in trauma with ISS > 14. We present an improved Mainz Emergency Evaluation Scoring system (MEES) in combination with capnometry (MEESc). MEESc is a new scoring system. ⋯ There were significant differences between MEES and MEESc. MEESc improved the results of MEES in predicting trauma outcome with ISS > 14. The prehospital use of the improved MEESc system could be an efficient communication protocol between the prehospital and hospital settings.
