RESUMO
PURPOSE: Traumatic intracranial hematoma (TICH) is a neurosurgical emergency with high mortality and morbidity. The time to operative decompression is a modifiable but inconsistently reported risk factor for TICH patients? OUTCOMES: We aimed to provide contemporary time to evacuation data and long-term trends in timing of TICH evacuation in a trauma system. METHODS: A 13-year retrospective cohort study ending in 2021 at a trauma system with one level-1 trauma center included all patients undergoing urgent craniotomy or craniectomy for evacuation of TICH. Demographics, injury severity and key timeframes of care were collected. Subgroups analyzed were polytrauma versus isolated head injury, direct admissions versus transfers and those who survived versus those who died. Linear regression of times from injury to operating room was performed. RESULTS: Seventy-eight TICH patients (Age: 35 (22-56); 58 (74%) males; ISS: 25(25-41); AIS head: 5 (4-5); mortality: 21 (27%) patients) were identified. Initial GCS was 8 (3.25-14) which decreased to 3 (3-7) by arrival in the trauma center. There were 46 (59%) patients intubated prior to arrival. Median time from injury to operation was 4.88 (3.63-6.80) hours. Linear regression of injury to OR showed increasing times to operative intervention for direct admissions to the trauma center over the study period (p=0.04). There was no associated change in mortality or Glasgow outcome score over the same time. CONCLUSION: This contemporary data shows timing from injury to evacuation is approaching 5 hours. Over the 13-year study period the time to operative intervention significantly increased for direct admissions. This study will guide our institutions response to TICH presentations in the future. Other trauma systems should critically appraise their results with the same reporting standard.
