What are the core quality metrics that should be tracked for every stroke patient?

Stroke Quality Metrics

Every stroke program should track a core set of performance metrics covering acute management, secondary prevention, and outcomes, with the 2023 World Stroke Organization guidelines providing the most comprehensive framework for implementation across all care settings. 1

Core Compulsory Metrics

The European Stroke Organisation identifies 6 mandatory quality indicators that every stroke unit must track 2:

1. Door-to-needle time <60 minutes for IV thrombolysis patients
2. Stroke unit admission rate - percentage of all acute stroke patients admitted to stroke unit (or ICU when appropriate)
3. Brain imaging completion - 100% of suspected stroke patients receiving CT or MRI
4. Antiplatelet therapy at discharge for ischemic stroke patients
5. Anticoagulation at discharge for patients with atrial fibrillation
6. Dysphagia screening - percentage of patients screened for swallowing disorders

Clinical Significance of Time Metrics

For every 15-minute reduction in door-to-needle time, there is a 5% lower odds of in-hospital mortality (adjusted OR 0.95% CI 0.92-0.98) 3. Despite this, only 26.6% of patients achieve the recommended ≤60 minute door-to-needle time, highlighting a critical quality gap.

Acute Management Metrics

The 2023 World Stroke Organization guidelines provide an extensive acute care metric framework 1:

Time-Critical Interventions

• Time from stroke onset to healthcare professional assessment (minutes/hours)
• Proportion receiving stroke severity assessment (e.g., NIHSS)
• CT scan within 25 minutes of hospital arrival
• Door-to-needle time for IV thrombolysis
• Proportion receiving IV thrombolysis among eligible patients
• Mechanical thrombectomy rates (both early and late window >6 hours)
• Successful recanalization (mTICI 2b/3) after thrombectomy

Early Hospital Care Processes

• Aspirin within 48 hours for ischemic stroke
• DVT prophylaxis administration rate
• Time to first mobilization from stroke onset
• Hemicraniectomy for eligible patients with large hemispheric infarction
• Patient/family stroke education delivery
• Distribution of discharge locations

Hemorrhagic Stroke Specific

• Time to antihypertensive therapy in ICH with hypertension
• Blood pressure control achievement in first 24 hours for ICH
• Anticoagulation reversal time for anticoagulation-related ICH
• Therapeutic anticoagulation within 24 hours for cerebral venous sinus thrombosis

Secondary Prevention Metrics

Critical secondary prevention indicators that directly impact recurrent stroke risk 1:

Diagnostic Evaluation

• Stroke etiology workup initiated within 48 hours
• Complete brain and vascular imaging (extracranial/intracranial)
• Cardiac monitoring ≥24 hours completion rate

Risk Factor Management

• Blood pressure assessment and treatment rates
• BMI documentation at time of event
• HbA1c ≤7% achievement in diabetic patients
• LDL-cholesterol <70 mg/dL (1.8 mmol/L) achievement rate
• Physical activity engagement (low/moderate intensity, 10 min, 4 days/week)
• Smoking cessation counseling for active smokers
• Alcohol reduction counseling (>2 drinks/day men, >1 drink/day women)
• Sodium intake <2000 mg daily

Specific Interventions

• Oral anticoagulation for atrial fibrillation patients
• PFO assessment by neurocardiology team for cryptogenic stroke
• PFO closure in eligible cryptogenic stroke patients (age 18-60)
• Carotid endarterectomy within 14 days for severe ipsilateral stenosis
• Dual antiplatelet therapy within 24 hours for minor stroke (NIHSS ≤3-5) or high-risk TIA (ABCD2 ≥4)

Additional Priority Metrics

The ESO recommends selecting at least 3 of these 7 additional indicators 2:

1. Vascular imaging completion in ischemic stroke/TIA
2. Brain imaging within 1 hour for patients arriving within 2 hours of onset
3. IV thrombolytic therapy utilization rate among eligible patients
4. Carotid revascularization for ≥50% symptomatic stenosis (NASCET criteria)

Implementation Framework

Data Collection Requirements

Every stroke unit must maintain 2:

• Local stroke register tracking: age, sex, initial stroke severity, thrombolysis status, discharge disposition, mortality
• Entry into regional/national databank for benchmarking
• Multidisciplinary team documentation (weekly meetings with logbook confirmation each patient discussed)

Quality Improvement Structure

Healthcare institutions should establish 3:

• Multidisciplinary quality improvement committee reviewing benchmarks and outcomes (Class I, Level B)
• Clinical process improvement team
• Stroke care data repository to identify gaps and disparities
• Written protocols for acute intervention and secondary prevention

Common Pitfalls to Avoid

1. Focusing only on process metrics without outcome tracking - The Get With The Guidelines-Stroke program demonstrates that systematic metric collection drives measurable improvements: IV rtPA use increased from 42.9% to 72.84%, and overall defect-free care improved from 44.0% to 84.3% over 5 years 3

2. Neglecting gender disparities - Data shows women receive less defect-free care (66.3% vs 71.1% for men) and are less likely to be discharged home, requiring targeted interventions 3

3. Inadequate documentation of exclusions - When patients don't receive standard treatments, documentation of reasons increased by 13% with quality programs, enabling better understanding of care gaps 3

4. Missing the 72-hour follow-up window - Patients with disabilities should be followed within 72 hours by specialist stroke rehabilitation teams 1

Outcome Metrics for Comprehensive Assessment

Beyond process measures, track 4:

• Neurological status at 24 hours
• Ambulatory status at discharge
• Modified Rankin Scale at 30 and 90 days
• Hospital mortality rates
• Discharge disposition patterns

The most recent 2023 World Stroke Organization synthesis provides the definitive framework, recognizing that hospitals should maintain data collection systems and participate in external stroke data repositories to enable continuous quality improvement and benchmarking 1.
