Outcome Measures
Primary Outcomes (1)
Change in t-PA use with assessment of appropriateness of use and complications.
The primary outcome was based on the change in the rate of tPA use between the "pre-intervention" period (Jan 2005 to Dec 2006) and the "post-intervention" period immediately following the conclusion of the first mock "code stroke / CME intervention (Jan 2008 to Jan 2010).
January 2005 to January 2010
Secondary Outcomes (4)
Changes in emergency physician knowledge and attitudes regarding thrombolytic use.
2007 to 2009
Intracerebral Hemorrhage
2007 to 2010
Systemic hemorrhage
2007 to 2010
tPA-use guideline deviations
2007 to 2010
Study Arms (2)
Intervention
ACTIVE COMPARATORControl
NO INTERVENTIONInterventions
Intervention hospitals received a barrier assessment - interactive educational intervention (BA-IEI) which included: on-site barrier assessment, annual "stroke champions" meetings, stroke center telephone access, quarterly mock stroke codes, and ongoing feedback and education.
Eligibility Criteria
You may qualify if:
- Physician staffed emergency department at all times
- /7 CT scanning availability
- Computerized pharmacy dispensing system for the emergency department or thrombolytic use log
- Agreement to participate and identified site investigator
You may not qualify if:
- Primary children's, psychiatric, or long-term (convalescent) care hospital
- Established academic comprehensive stroke center (Detroit Receiving Hospital, Henry Ford Hospital, University of Michigan)
- Annual emergency department volume greater than 100,000 patients per year (only one hospital)
