Pop Quiz: Do We Really Need To Do All That? The Answer

The scenario involved an elderly woman who fell from standing at her care facility 12 hours earlier. They want to send her to your trauma center for evaluation because she seems a bit different from her baseline. You have well defined practice guidelines for patients with head injuries that dictate what type of monitoring and diagnostics they receive.

What do you need to know to determine what you should do? Thanks for all of you who sent in suggestions.

Here are my thoughts:

  • Which scans should she get? Usually, you would obtain an initial head CT and, due to her age, a cervical CT regardless of her physical exam due to the high miss rate in these patients. But now the fun begins. Your subarachdoid / intraparenchymal hemorrhage (IPH) practice guideline would have you admit for neurologic monitoring for 12 hours, obtain a TBI screen, then discharge without a followup scan if the screen was passed. But in this case, the clock started 12 hours ago and the guideline would be finished with the exception of the TBI screen. So an initial scan and a TBI screen in the ED are all that are needed. The observation period is already over and the patient could potentially be discharged from ED if a SAH or IPH were found.
    Your subdural guideline mandates all of the above plus a repeat scan at 12 hours. But once again, the clock has already started. Do you just get an initial scan, which also serves as the 12 hour scan? Or do you get yet another one?  If the neuro exam is normal, I vote for the former, and your evaluation is complete after the TBI screen. If the neuro exam is not quite normal, then admission for continuing exams and a repeat scan are in order.
  • Does the patient need to be admitted, and for how long? Hopefully, you’ve figure this out in the previous bullet. The clock started running when she fell down, so in cases where the physical exam is normal, only the first CT is needed and ongoing monitoring is not. Thus, she could return to her care facility from the ED after the scan.
  • What other important information do you need to know? Of paramount importance is her DNR status and her/her family’s willingness to have brain surgery if a significant lesion is identified. It is extremely important to know the latter item. If there is never any patient or family intent to proceed to surgery, is there any point to obtaining scans at all? In my opinion, no. The whole reason to obtain the scan and monitor is to potentially “do something.” But if the patient and/or family will not let us “do something,” there is no reason to do any of this. It is crucial that the patient and family understand the typical outcomes from surgery given her age and degree of frailty. This is most important in patients who are impaired with dementia or a high-grade lesion  if found from which there is minimal chance of recovery. In most such cases, even if surgery is “successful,” the patient will never recover enough to return to their prior level of care. This should be weighed heavily by the family and care providers.
  • Should a patient with DNR or “no surgery” orders even be sent to the ED? Theoretically, no. There is no need from the standpoint of their future care. They are not really eligible to have any studies or monitoring done. However, the facility may try to insist for their own liability issues, but this is not really a valid clinical reason.
