1. INF GR / PS / 16 Pedestrians injury profile evaluation in a hospital-based multicenter polytrauma survey S. Prat-Fabregat Trauma Unit

2. Multicenter survey Variaciones en la práctica asistencial y en los resultados de la atención al paciente traumático accidentado de tráfico en Catalunya Dr. S. Prat Hospital Clínic Dr. A. Plasència Institut Municipal Salud Barcelona Agència Avaluació Tecnologia i Recerca Mèdiques

3. Inclusion criteria Road traffic accident with: ICU admission Surgical procedure ISS > 10 Exclusion: Not road traffic accident Dead before ED admission

4. Study population Total cases: 508 Hospital distribution: – Bellvitge H1 87 – Clínic H2 150 – Girona H3 33 – Parc Taulí H4104 – Vall d’Hebró H5134

5. Type of accident (by hospital)

6. ICD-9-CM 92 different diagnostic groups Most frequent ICD codes: – Cranioenecephalic and craniofacial trauma (801-804 y 850) – Pelvic, upper and lower extremity fractures (810-816, 820-825, 808, 831-844) – Thoracic trauma (807, 860-862)

7. ICD-9-CM Diagnostic Groups

8. Injury pattern in collision with cranial trauma

9. Injury patterns in pedestrians with cranial trauma

10. Injury patterns in collision without cranial trauma

11. Injury patterns in pedestrians without cranial trauma

12. Injury patterns in motorcycle accident with cranial trauma

13. Injury patterns in motorcycle accident without cranial trauma

14. Max AIS in motorcycle accident with at least 3 AIS anatomic areas involvement

15. Max AIS in pedestrians with at least 3 AIS anatomic areas involvement

16. Vital status at hospital discharge: collisions Overall mortality 10,2%

17. Overall mortality: 20,1% The bigger the age, the bigger the pedestrians incidence (p< 0.01) Vital status at hospital discharge: pedestrians

18. Conclusions: From the 508 road traffic accidents studied (104 of which were pedestrian accidents), the mortality rate for the pedestrians is twice that for the car occupants There is a clear relationship between increasing age and the risk of having a pedestrian accident (The average age of the injured pedestrian in this survey is 59 years) The majority of the pedestrians were injured in two or more body regions; 60% of them required IC. The average time of hospitalization was 22 days, and an average of 8 days in the ICU
