Objective: Conduct a comparative analysis of injury severity (IS) caused by traffic accidents (TA) and classified as severe injury (SI) in police database vs. MAIS 3+ injury in hospital database, and determine correction factor (CF). Methods: Data were collected prospectively on the injured in TA examined by Emergency medical services. Were identified the numbers of fatalities, the numbers of patients transported to hospitals, and those examined at the scene of TA who refused further medical treatment and transport. IS was asssessed in hospital according to ICD, AIS and MAIS for each patient. The data on SBI were compared vs. MAIS 3+ and CF was determined. Results: 134 respondents were included: 55 drivers, 37 passengers, 23 pedestrians, 17 motorcyclists and 2 cyclists. 12% out of 17% of MAIS 3+ patients were hospitalized. One patient with MAIS 5 died during the hospitalization. The comparative analyisis of IS as assessed in the police vs hospital database showed the ratio SI : MAIS 3+ to be 1.2. Eighteen SIs belonged to MAIS 3+, one to MAIS 1 and one to MAIS 2. Four patients with MAIS 1 and 2 score sustained no injuries, according to the police report. Six moderate IS according to police data were classified as MAIS 3 in hospital registers. CF for MAIS 3+ was 0.316 and for minor IS was 0.016. Conclusion: The results confirm that there are discrepancies in assessments of IS between police and hospital records and that it is neccessary to form a common database.
