Summary
Stroke thrombolysis utilization is low in the community. Prompt admission to hospitals offering thrombolysis is crucial for improving treatment rates and patient outcomes.
Area of Science:
- Neurology
- Public Health
- Emergency Medicine
Background:
- Thrombolysis is a critical treatment for acute ischemic stroke.
- Assessing thrombolysis barriers in population-based studies is less common than in hospitalized cohorts.
- Understanding community-level utilization and barriers is essential for optimizing stroke care delivery.
Purpose of the Study:
- To determine the community-wide utilization rate of stroke thrombolysis.
- To identify barriers to thrombolysis in a geographically defined population.
- To evaluate the role of the stroke care provider as a potential barrier.
Main Methods:
- Post-hoc analysis of a prospective, population-based stroke study in Basel-City, Switzerland.
- Inclusion of permanent residents with stroke onset assessment interval (OAI) less than or equal to 3 hours.
- Comparison of demographic variables, NIHSS score, OAI, risk factors, and stroke care provider between thrombolyzed and non-thrombolyzed patients.
Main Results:
- A total of 269 stroke patients were analyzed; 49 had an OAI ≤3 hours.
- Thrombolysis utilization was 5.2% overall and 29% in the OAI ≤3-hour cohort.
- Barriers included mild/regressing stroke severity (48%), non-thrombolysis-offering hospitals (20%), contraindications (17%), and comorbidity (14%). Admission to a stroke unit significantly increased thrombolysis rates (35% vs. 0%).
Conclusions:
- Late admission remains the primary barrier to thrombolysis in the general stroke population.
- For eligible patients (OAI ≤3 hours), hospital type significantly impacts thrombolysis rates, with non-thrombolysis-offering facilities excluding patients as often as contraindications.
- Acute stroke patients should be transported directly to hospitals equipped for thrombolysis to maximize treatment access.

01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:29Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
01:29Stroke: Introduction and Types
A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
