Isolated Traumatic Brain Injury in the Very Old

Background: Older age is an independent predictor of worse outcome from traumatic brain injury (TB)). No clear guidelines exist for the management of TBI in elderly patients. Objectives: To describe the outcomes of elderly patients presenting with TBI and intracranial bleeding (ICB), comparing a very elderly population (>= 80 years of age) to a younger one (70-79). Methods: Retrospective analysis of the outcomes of elderly patients presenting with TBI with ICB admitted to a level I trauma center. Results: The authors analyzed 100 consecutive patients aged 70-79 and 100 patients aged 80 and older. In-hospital mortality rates were 9% and 21% for groups 70-79 and >= 80 years old, respectively (P = 0.017). Patients 70-79 years old showed a 12-month survival rate of 73% and a median survival of 47 months. In patients >= 80 years old, 12-month survival was 63% and median survival was 27 months (P = NS). In patients presenting with a Glasgow Coma Scale score of >= 8, the in-hospital mortality rates were 41% (n=5/12) and 100% (n=8/8). Among patients >= 80 years old undergoing emergent surgical decompression, in-hospital mortality was 66% (n=12/18). Survivors presented with a severe drop in their functional score. Survival was dismal in patients 80 years old who were treated conservatively despite recommended operative guidelines. Conclusions: There is a lack of reliable means to evaluate the outcome in patients with poor functional status at baseline. The negative prognostic impact of severe TB) is profound, regardless of treatment choices.
