Table 2.

Estimated Total Costs for Usual Care Strategy a,b,c

End node Cost ($)
 No CT, no TBI or ciTBI, discharged home 756
 CT, no TBI or ciTBI, discharged home 950
 CT, no TBI or ciTBI, admitted 2,024
 CT, TBI, admitted 4,507
 CT, ciTBI, admitted, no neurosurgery 4,638
 CT, ciTBI, neurosurgery 8,061

Abbreviations: CT, computed tomography; TBI, traumatic brain injury; ciTBI, clinically important traumatic brain injury

a

- assigned a log-normal distribution in the probabilistic sensitivity analysis

b

- total costs differed slightly (range $4 to $14) for each of the end nodes of the PECARN strategy as the probability of ED observation differed between risk categories (see eTable 6 for cost and probability of ED observation)

c

– see eTable 6 and 7 for individual costs inputs and cost summaries
