Mild traumatic brain injury and imaging
- CDC, Acute Concussion Evaluation, provider tool. Source of the description of concussion, of the statement that it may or may not involve a loss of consciousness, and of the explanation that the disturbance is related to neurometabolic dysfunction rather than structural injury and is typically associated with normal structural neuroimaging findings. CDC.
- CDC, About Mild TBI and Concussion. Source of the statement that even if the injury does not show up on these tests you may still have a mild TBI or concussion, that a scan is not needed to spot one, and of the explanation that providers describe these injuries as mild because they are usually not life-threatening while the effects can be serious. CDC.
- CDC, pediatric mild traumatic brain injury clinical guidance. Source of the direction to providers not to image routinely and to use validated clinical decision rules to determine need. CDC.
On the pediatric guidance. That document addresses children, and we have cited it for a narrow proposition: that clinical guidance discourages routine imaging and reserves it for identifying more severe injury. We have not extended anything else from it to adults, and a clinician is the right person to say what applies to any individual.
Why there is no settlement figure here. We have not published a range or an average, because we have no sourced basis for one and because the largest components of these claims are the least standardised. Any figure would be a guess wearing the clothes of information. What a claim is worth depends on the individual loss and, just as importantly, on what insurance exists to pay it.
What we have left out. We have given no prevalence, incidence or recovery statistic, because the CDC material we read this session did not provide one we could state precisely in this context. We have not set out the severity classification bands, which reached us through secondary sources rather than CDC material we read directly. And we have reproduced no material published by medical journals, professional societies or private research bodies, which is their copyrighted work rather than public information.
