Major blunt trauma causes increased mortality up to 12 years: Long-term survival in 3 557 patients compared to 35 502 control persons.

Background: Trauma registries usually report 30-day or in-hospital mortality as an outcome measure. However, some studies criticize this measure as inadequate; the impact of a major trauma could last longer than 1 month after the injury. We studied the long-term mortality of patients who sustained a major trauma.
