Weekend admissions for ischemic stroke are linked to higher mortality. This "weekend effect" impacts stroke outcomes regardless of hospital setting or physician specialty, suggesting potential care disparities.

Area of Science:

  • Neurology
  • Public Health
  • Healthcare Management

Background:

  • Weekend admissions are linked to increased in-hospital mortality.
  • The specific impact of the "weekend effect" on stroke mortality requires further investigation.

Purpose of the Study:

  • To evaluate the impact of weekend admissions on stroke mortality.
  • To analyze stroke mortality differences across various healthcare settings.

Main Methods:

  • Analysis of ischemic stroke admissions from April 2003 to March 2004 using the Canadian Hospital Morbidity Database.
  • Inclusion criteria: acute care facility admission with a principal diagnosis of ischemic stroke.
  • Inclusion of clinical variables and facility characteristics in the analysis.

Main Results:

  • 26,676 ischemic stroke admissions were analyzed.
  • Weekend admissions (24.8%) showed higher stroke mortality (8.5%) compared to weekday admissions (7.4%).
  • Multivariable analysis confirmed weekend admissions were associated with higher early mortality (OR, 1.14; 95% CI, 1.02 to 1.26) after adjustments.

Conclusions:

  • Stroke patients admitted on weekends face a higher risk-adjusted mortality.
  • Potential explanations include disparities in weekend resources, expertise, and healthcare provider availability.
  • The findings highlight a significant weekend effect on stroke outcomes.
