Survival after severe brain injury in the aged

Area of Science:

• Trauma Surgery
• Neurosurgery
• Geriatric Medicine

Background:

• Severe blunt brain injury presents unique challenges in patient management.
• Age is a significant factor influencing outcomes in traumatic brain injury (TBI).

Purpose of the Study:

• To investigate the impact of age on mortality and functional recovery in patients with severe blunt brain injury.
• To compare outcomes and resource utilization between elderly and younger patients with similar injury severity.

Main Methods:

• Retrospective cohort study at a Level 1 trauma center.
• Comparison of 42 elderly patients (≥60 years) with 50 younger patients (20-40 years) with Glasgow Coma Scale (GCS) scores ≤5.
• Analysis of mortality rates and quality of survival using Glasgow Outcome Scale (GOS) scores.

Main Results:

• No differences in initial injury severity scores (GCS, RTS, ISS, AIS) or treatment intensity between age groups.
• Elderly patients had higher in-hospital mortality (79% vs. 36%) and a greater incidence of brain confusion and multiple lesions.
• Favorable recovery (GOS) was significantly lower in elderly (2%) versus younger patients (38%), with substantially higher costs per favorable outcome in the elderly.

Conclusions:

• Elderly patients with severe blunt brain injury face higher mortality and poorer functional recovery compared to younger counterparts.
• Older patients are more prone to secondary organ failure and consume more healthcare resources per successful outcome.
• Age is a critical determinant of outcomes in severe TBI, necessitating tailored management strategies.
