What is Repeat Head Computed Tomography for Anticoagulated Patients with an Initial Negative Scan Is Not Cost-effective about?
## Background: Patients on antithrombotic medications presenting with blunt trauma are at risk for delayed intracranial hemorrhage. we hypothesized that clinically significant delayed intracranial hemorrhage is rare in patients presenting on antithrombotic medications and therefore routine, repeat head computed tomography imaging is not a cost-effective practice to monitor for delayed intracranial hemorrhage. ## Methods: Patients presenting to our institution on antithrombotic (anticoagulant and antiplatelet) medications during a 5-y period from january 2014 through march 2019 who underwent a head computed tomography for blunt trauma were identified in our trauma registry. patients with an initial negative head computed tomography underwent repeat imaging 6 h after their initial head computed tomography. patient demographics, antithrombotic medication, international normalized ratio, glasgow coma score, clinical change in neurologic status, and need for neurosurgical intervention were collected. ## Results: Our institution evaluated 1,676 patients on antithrombotic therapy with blunt trauma. the initial head computed tomography was negative in 1,377 patients (82.0%). of those with
