Deaths after the initial hospitalisation

Of the 23,445 patients in the cohort, 856 (3.7%) died within 2 years of the initial TBI hospitalisation. This includes patients that died during the initial TBI hospitalisation, however, the cause of these deaths was not necessarily TBI (Figure 26; Table S10). The TBI diagnosis with the highest percentage of deaths 2 years after hospitalisation was traumatic subdural haemorrhage as a principal diagnosis – 11% (72) of those patients died within 2 years. The TBI diagnosis with the lowest percentage of deaths 2 years after hospitalisation was concussion as a principal diagnosis – 1.0% (100) of those patients died within 2 years.
