Operative versus non-operative treatment of traumatic brain injuries in patients 80years of age or older.

Abstract

Traumatic brain injury (TBI) in older adults is an increasing issue in modern medicine. Nevertheless, it remains unclear which patients presenting with TBI and 80years of age or older benefit from an operative treatment. The aim of this study was to explore the effect of an operative treatment in isolated TBI patients ≥ 80years of age. Data were derived from the TraumaRegister DGU® from 2002 to 2016. Inclusion criteria were ≥ 80years of age, an Abbreviated Injury ScaleHead (AIS) ≥ 3, and an AISNon-Head ≤ 1. The cohort was split in operatively and non-operatively treated patients, and outcome was assessed at discharge using the Glasgow Outcome Scale (GOS). A favorable outcome was defined as a GOS of 4 or 5. A total of 1.693 patients (431 operatively and 1.262 non-operatively treated patients) were analyzed. Mortality rate was 54.4% (687 patients) in the non-operative group and 49.4% in the operative group. Simultaneously, there were more patients discharged with a GOS 2 (persistent vegetative state) in the operative group (7.9%, 34 patients) than in the non-operative group (1.0%, 13 patients). An analysis of the operatively treated patients showed an association between a higher mortality risk and brainstem hemorrhage (p = 0.04), fixed pupils (p = 0.001), initial intubation (p = 0.03), and an AISHead of 5/6 (p = 0.03). Patients 80years of age or older seem to benefit from an operative treatment regarding mortality rate. However, there has been a higher rate of a poor neurological outcome particularly with regard to persistent vegetative state in the operative treatment group at discharge.
