3. Introduction Scoring systems are usually used for clinical research by dividing patients into comparable groups. The results from researches are used to evaluate and improve patient management, care and survival. Multiple trauma scores are used to assess injury severity sustained by a patient. Scoring systems can be used to predict outcome from trauma, but their use is limited and they are usually difficult to calculate in clinical practice.

Crit Care Med. 2009;37(6):1972-7. „Validation of the score, using a dataset containing 3314 severely injured patients showed it to outperform the RTS, ISS, NISS and TRISS“ (Nijboer, J.M.M.

8. Emergency Trauma Score (EMTRAS) Comprises 4 parameters: Glasgow Coma Scale (GCS) Patient age Base excess (BE) Prothrombin time (PT). Each parameter is subdivided into four classes, scored from 0 to 3 points. Scores of each class are summed to obtain the EMTRAS, ranging from 0 to 12. Raum MR, Nijsten MW, Vogelzang M, et.

10. Our study A retrospective analysis of all patients (334) who were admitted to the resuscitation bay during a period of one year (2012) at our trauma center was performed. The EMTRAS as well as ISS were calculated and compared to mortality of the patients

11. Our study Out of 334 patients EMTRAS was not possible to calculate for 120 (36%) patients due to missing data.

13. Analysis

14. Problems with the study No exclusion criteria Out of 334 patients EMTRAS was not possible to calculate for 120 (36%) patients due to missing data – which was usually the BE obtained by arterial blood gas analysis not usually done in example children with fewer cramps, hospital transfers, etc. Field GCS is elusive

15. Conclusion EMTRAS is practical and easy to calculate in clinical practice. EMTRAS is a good predictor of mortality. Further validation of the EMTRAS score is required. EMTRAS score of seven or more should alert the trauma team trating the patient. Decisions for individual patients should never be based solely on a statistically derived score.
