This study used the modified Brain injury Guidelines retrospectively to assess whether the guidelines would have saved transfers to their level one facility safely. They concluded the guidelines would have effectively prevented unnecessary mBIG 1 and mBIG2 transfers with no patient harm.
TABLE 1 - Modified Brain Injury Guidelines Radiologic Stratification, as per Kahn et al.
| mBIG 1 | mBIG 2 | mBIG 3 | |
|---|---|---|---|
| Skull fracture | No | Non-displaced | Displaced |
| SDH | ?4 mm | 4–7.9 mm | ?8 mm |
| EDH | No | No | Yes |
| SAH | ?3 sulci and <1 mm | Single hemisphere or 1–3 mm | Bihemisphere or >3 mm |
| IVH | No | No | Yes |
| IPH | ?4 mm | 4–7.9 mm | ?8 mm or multiple |
EDH, epidural hematoma; IPH, intraparenchymal hemorrhage; IVH, intraventricular hemorrhage; SAH, subarachnoid hemorrhage.
