The investigators are testing whether a new nurse-led safety program (HFMEA) lowers problems during emergency brain-aneurysm surgery better than usual care.
Adults with a sudden brain bleed (subarachnoid hemorrhage) who need urgent clipping or coil placement at the hospital are randomly placed in one of two groups:
Usual nursing care, or Usual care plus HFMEA (nurses use checklists to spot and prevent risks such as re-bleeding, high brain pressure, infection, seizures).
The investigators count how often any nursing-related problems happen within 30 days after surgery, how long patients stay, and how satisfied the participants and their families are.
Results will show if this extra safety program should become standard practice.
