2021 Head injury Guidelines for Patients on Direct Oral Anticoagulants (DOACs)

2021 Head Injury Guidelines for Patients on Direct Oral Anticoagulants (DOACs): Case

The American Academy of Emergency Medicine (AAEM) published a clinical practice statement in April 2021 addressing the risk of delayed intracranial hemorrhage after a mild traumatic brain injury in patients taking direct oral anticoagulants (DOACs).  What does these 2021 head injury guidelines recommend with regards to routine repeat Head CT scans in this subpopulation?

Try this review question and find out if you’re following the most current 2021 head injury guidelines.

An 84-year-old male presents to the emergency department (ED) after falling in the bathroom and hitting his head on a tile floor.

The fall was due to a loss of balance.

He did not lose consciousness and presents now with a 4-cm hematoma on the forehead at the lateral prominence of the left supraorbital ridge.

He is neurologically intact except for chronic gait instability secondary to spinal stenosis.

He takes a direct oral anticoagulant, but no anti-thrombotic medication.

A head CT scan without contrast is negative.

Question:

Which of the following statements is true regarding a delayed second head CT scan in this patient anticoagulated through DOACs if he remains neurologically intact?

Answer Options:

The data is currently not strong enough to formally recommend for or against repeat imaging.

A second computed tomography (CT) of the head after 3 hours is recommended.

The patient should be observed in the ED for 3 hours; if there is no neurological deterioration, the patient can be discharged without a second head CT scan.

Different from patients on vitamin K inhibitors (e.g. warfarin), patients on DOACs do not require a repeat head CT or an observation period after minor head trauma and a negative first head CT scan.
