RESUMO
BACKGROUND: Many institutions obtain a delayed head CT in patients presenting after a ground level fall while on anticoagulation. This study evaluates their risk of delayed ICH. METHODS: Retrospective chart review of 635 patients on anticoagulation who sustained a ground level fall with a negative initial head CT and a GCS above eight. Patients underwent a repeat head CT within 48 h. The ISS was calculated for all patients. RESULTS: Five patients had a delayed ICH. All survived and none required neurosurgical intervention. Patient variables did not have any correlation with development of ICH. Patients with a delayed ICH had a significantly higher ISS. CONCLUSION: Patients on anticoagulation presenting to the hospital after a ground level fall, with a GCS above eight and an initial negative head CT, do not need to undergo repeat imaging. ISS could be used to stratify patients who are at higher risk of delayed ICH.
