Implementation of the Modified Brain Injury Guidelines Might Be Feasible and Cost-Effective Even in a Nontrauma Hospital

INTRODUCTION: The modified Brain Injury Guidelines (mBIG) provide a framework to stratify traumatic brain injury (TBI) patients based on clinical and radiographic factors in level 1 and 2 trauma centers. Approximately 75% of all U.S. hospitals do not carry any trauma designation yet could also benefit from these guidelines. To the best of our knowledge, this is the first report of applying the mBIG protocol in a community hospital without any trauma designation. METHODS: All adult patients with a TBI in a single center from 2020 to 2022 were retrospectively classified into mBIG categories. The primary outcomes included neurological deterioration, progression on computed tomography of the head, and surgical intervention. Additional outcomes included the hospital costs incurred by the mBIG 1 and mBIG 2 groups. RESULTS: Of the 116 included patients, 35 (30%) would have stratified into mBIG 1, 23 (20%) into mBIG 2, and 58 (50%) into mBIG 3. No patient in mBIG 1 had a decline in neurological examination findings or progression on computed tomography of the head or required neurosurgical intervention. Three patients in mBIG 2 had radiographic progression and one required surgical decompression. Two patients in mBIG 3 demonstrated a neurological decline and six had radiographic progression. Of the 21 patients who received surgical intervention, 20 were stratified into mBIG 3. Implementation of the mBIG protocol could have reduced costs by >$250,000 during the 2 -year period. CONCLUSIONS: The mBIG protocol can safely stratify patients in a nontrauma hospital. Because nontrauma centers tend to see more patients with minor TBIs, implementation could result in significant cost savings, reduce u nnecessary hospital and intensive care unit resources, and reduce transfers to a tertiary institution.
