FIG. 1.

Proportion of mean total intramural costs per cost- category according to severity of traumatic brain injury (TBI). The proportion of the total intramural costs from each cost category are plotted in a histogram for each TBI severity level separately. The exact percentage for each cost category (including pre-hospital costs, intensive care unit and ward admission costs, intra- and extracranial surgery costs, laboratory costs, imaging costs, blood products costs, and rehabilitation costs) are presented in the table below the figure. For example, of the total costs within the mild TBI category, 7% of the expenses were from pre-hospital costs.
