BackgroundAcute subdural hematoma (ASDH) is a common pathology following traumatic brain injury (TBI). There is sparse data on the prediction of clinical outcomes following traumatic ASDH (tASDH) evacuation. We investigated prognosticators of outcome following evacuation of tASDHs, with subset analysis in a cohort of octogenarians. We developed a scoring system for stratifying the risk of in-hospital mortality for patients undergoing tASDH evacuation.MethodsA retrospective chart review was performed to identify all patients who underwent tASDH evacuation. Baseline clinical and demographic data including age, traumatic brain injury mechanism, admission Glasgow Coma Scale (GCS), and Rotterdam computed tomography Scale (RCS) were collected. In-hospital outcomes such as mortality and discharge disposition were collected. A scoring system (tASDH Score) which incorporates RCS (1-2 points), admissions GCS (0-1 points), and age (0-1 point) was created to predict the risk of in-hospital mortality following tASDH evacuation.ResultsBeing an octogenarian (OR = 6.91 [2.20-21.71], P = 0.0009), having a GCS of 9-12 (OR = 1.58 [1.32-4.12], P = 0.027) or 3-8 (OR = 2.07 [1.41-10.38], P = 0.018), and having an RCS of 4-6 (OR = 3.49 [1.45-8.44], P = 0.0055) were independently predictive of in-hospital mortality. The in-hospital mortality rate was lower for those with a tASDH score of 1 (10%), compared to those with a score of 2 (12%), 3 (42%), and 4 (100%).ConclusionsOctogenarians with an RCS of 4-6 and an admission GCS <13 have a high risk of mortality following tASDH evacuation. Knowledge of which patients are unlikely to survive ASDH evacuation may help guide neurosurgeons in prognostication and goals of care discussions.Copyright © 2023 Elsevier Inc. All rights reserved.
