Weekend admission did not worsen outcomes for ischemic stroke patients in a large comprehensive stroke center. This suggests organized stroke care, not admission timing, is key for better patient results.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Public Health
Background:
- Previous research indicated higher mortality for ischemic stroke patients admitted on weekends.
- A potential 'weekend effect' in stroke care outcomes has been a subject of concern.
Purpose of the Study:
- To investigate if weekend admission is linked to poorer outcomes in ischemic stroke patients.
- To evaluate the 'weekend effect' in a large cohort from a comprehensive stroke center (CSC).
Main Methods:
- Retrospective analysis of consecutive ischemic stroke patients admitted within 6 hours of symptom onset.
- Exclusion of patients receiving intra-arterial therapy or in non-observational trials.
- Comparison of outcomes between weekday and weekend admissions using multivariate logistic regression, adjusting for age, NIHSS, and glucose levels.
Main Results:
- No significant difference in tissue plasminogen activator treatment rates between weekday and weekend admissions.
- Weekend admission was not a significant predictor of in-hospital mortality, length of stay, or discharge disposition.
- No significant differences observed in favorable functional outcomes at discharge or 90-day mortality between the groups.
Conclusions:
- The 'weekend effect' was not observed in this large cohort of ischemic stroke patients treated at comprehensive stroke centers.
- Access to 24/7 stroke specialists and organized stroke care systems likely mitigate the 'weekend effect'.
- Findings suggest re-evaluating EMS protocols for preferential weekend stroke patient transport to comprehensive stroke centers.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
