To observe or not to observe: Evaluation of the modified brain injury guideline management of small volume intracranial hemorrhage

Introduction: Patients with small volume intracranial hemorrhage (ICH) are categorized as modified Brain Injury Guidelines (mBIG) 1 and are managed with a 6-h emergency department (ED) observation period. The current study aimed to describe the mBIG 1 patient population and determine the utility of the ED observation period. Methods: A retrospective analysis was performed on trauma patients with small volume ICH. Exclusion criteria were Glasgow Coma Scale (GCS) < 13 and penetrating injuries. Results: 359 patients were identified over the 8-year study period. The most common ICH was SDH (52.7%) followed by SAH (50.1%). Two patients (0.56%) had neurologic deterioration, but neither had radiographic progression. Overall, 14.3% of the cohort had radiographic progression; none required neurosurgical intervention. Four patients (1.1%) had readmission related to TBI from the index admission. Conclusion: There were no patients with small volume ICH that required neurosurgical intervention despite a small subset of patients having radiographic or clinical deterioration. Patients who meet the mBIG 1 criteria may be managed safely without an ED observation period. (c) 2023 Elsevier Inc. All rights reserved.
