"CONFLICT OF INTEREST Nothing to declare."

"FUNDING INFORMATION Department funding only."

"Danish trauma centers use the Abbreviated Injury Scale (AIS) to score each injury sustained by trauma patients., The ISS is calculated based on the assigned AIS scores done by AIS‐certified physicians and medical students. To avoid interpersonal discrepancies between AIS scores assigned, the coding team regularly discussed cases and reviewed the process of assigning codes to assure consistency. Severe injuries were defined as ISS > 15. Data for 30‐day mortality were retrieved from patients' medical records using the Danish Civil Registration number (CRS). The Danish Civil Registration System contains a vital status for all Danish citizens and non‐citizens who reside in Denmark. "
