Long-term outcome after severe head injury.

Area of Science:

• Neurology
• Trauma Surgery

Background:

• Head injuries are a significant cause of long-term disability.
• Understanding the long-term prognosis of severe head injuries is crucial for patient care and resource allocation.

Purpose of the Study:

• To assess the long-term outcomes of patients with severe head injuries (unconsciousness or amnesia for ≥1 week).
• To identify predictors of outcome following severe head injury.
• To estimate the annual incidence of long-term disability from head injuries in England and Wales.

Main Methods:

• Retrospective cohort study of 7000 head injury patients.
• Follow-up of 479 patients with prolonged unconsciousness/amnesia (≥1 week).
• Examination of survivors and establishment of cause of death for non-survivors.

Main Results:

• Ten years post-injury, 4% were totally disabled and 14% severely disabled.
• 49% of patients recovered, while the remainder died.
• Age at injury, neurological responsiveness, and duration of post-traumatic amnesia reliably predicted outcome.

Conclusions:

• Severe head injuries result in substantial long-term disability.
• Prognostication is feasible based on specific injury characteristics.
• There is a need for enhanced patient and family support in the initial recovery phase.
