Outcome evaluation following subarachnoid hemorrhage.

Area of Science:

• Neurology
• Neurosurgery
• Public Health

Background:

• Aneurysmal subarachnoid hemorrhage (SAH) is a critical neurological event with significant mortality and morbidity.
• Traditional prognostic indicators like the Hunt and Hess scale may not fully capture long-term functional outcomes.

Purpose of the Study:

• To evaluate the long-term physical, cognitive, and psychosocial outcomes of patients following aneurysmal subarachnoid hemorrhage.
• To assess the utility of integrating computerized tomography (CT) findings with clinical grading for improved prognosis prediction.
• To advocate for the inclusion of cognitive and psychosocial disturbances in outcome assessment systems.

Main Methods:

• Retrospective analysis of 78 aneurysmal subarachnoid hemorrhage (SAH) patients from 1983.
• Classification using Hunt and Hess neurological grades and CT-modified grades.
• One-year follow-up assessing physical recovery, morbidity, and mortality.
• Extended follow-up for a subset of patients evaluating quality of life, cognitive function, and psychosocial adjustment.

Main Results:

• At one year, only 41% of SAH patients achieved good physical recovery, with a 37% overall mortality rate.
• A significant proportion of patients with initially good neurological outcomes experienced severe cognitive and psychosocial impairment.
• When functional morbidity was included, only 33% of all patients had a favorable outcome.

Conclusions:

• Traditional outcome measures for SAH may underestimate long-term disability.
• Persistent cognitive and psychosocial deficits significantly impact functional recovery after SAH.
• Future outcome grading systems should incorporate comprehensive assessments of cognitive and psychosocial status.
