Trauma registry data were combined with administrative registry data to obtain long-term mortality and in-hospital treatment. The in-hospital treatment data was from 2 years preceding the index injury and up to 5 years post injury. Reasons for the in-hospital visits were also recorded. We analyzed the patients in two groups, namely patients without a pre-existing psychiatric diagnosis (group 1) and patients with a pre-existing psychiatric diagnosis (group 2).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      One-hundred twenty-seven patients were included in the analysis, with 73 patients having received pre-existing psychiatric treatment. A total of 57% of patients were males and 28% of patients suffered severe traumatic brain injury (head AIS\u2009\u2265\u20093). Group 2 patients had a higher number of in-hospital days pre- and post-injury than group 1 patients. Reason for in-hospital treatment in group 2 was psychiatric in over 80% of days except in the year beginning from the index injury. 30-day mortality was similar between the groups 1 and 2 (11% vs. 16%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.395).
