About

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.

Full description

A single-center randomized trial of adults patients undergoing emergency repair for ruptured brain aneurysms was trying to determing that if proactive "Healthcare Failure Mode and Effect Analysis" (HFMEA) could lower the rate of nursing-related adverse events from 1 in 5 patients to fewer than 1 in 15.

Nurses trained in HFMEA mapped every step of care-from arrival through discharge-identified the 12 highest-risk moments (e.g., delayed pressure checks, missed re-bleeding signs), and built checklists, alert thresholds, and team huddles to stop problems before they started.

aim: adding a structured, forward-looking safety drill to routine neuro-critical nursing appears to spare two out of every three avoidable complications after emergency "brain-aneurysm" surgery without extra technology or cost.

156 participants in 2 patient groups

Intervention group

Experimental group

Description:

Patients assigned to the intervention arm received every element of conventional emergency neurosurgical care plus a structured, prospective safety overlay derived from Healthcare Failure Mode and Effect Analysis. The add-on programme was delivered by a nine-member, hospital-authorised HFMEA team (one chief neurosurgeon, two attending neurosurgeons, one head nurse, four bedside nurses, one quality-manager) who had completed an 8-hour training course on HFMEA principles, risk-priority-number (RPN) scoring and decision-tree analysis. The programme ran from the minute the participant arrived in the emergency department until 30-days post-operation and consisted of six sequential steps that were re-applied every month.

Treatment:

Behavioral: HFMEA-based nursing-risk programme

Control group

No Intervention group

Description:

The control group received conventional nursing risk management, including: 1. Admission assessment: vital signs monitoring, neurological function assessment, Hunt-Hess grading; 2. Preoperative nursing: condition observation, psychological care, preoperative preparation; 3. Postoperative nursing: close monitoring of vital signs, neurological function observation, complication prevention; 4. Health education: disease knowledge, precautions, rehabilitation guidance; 5. Discharge guidance: medication instructions, follow-up arrangements, lifestyle recommendations.
