CLEVELAND ACUTE STROKE EXPERIENCE
• Cleveland Health Quality Choice– stroke data collected by trained abstractors since 1991– IV tPA datapoints added 1996– disbanded 1998
• Cuyahoga County Operation Stroke 1999– data collection instrument designed by the Medical Committee and
The Stroke Group (ETHOSR)
• grants from Genentech/Astra Zeneca
• Cleveland Clinic Health System Stroke QI Program– presented to JCAHO 4/01

• Retrospective cohort of 16 community based hospitals 5/96-12/98
• 67% (42/63) major protocol deviations– dosing errors– >3 hours– known increased bleeding risk (eg low platelets)
• Serious extracranial hemorrhage 17% (NINDS 2%)
• In-hospital mortality 31% (NINDS 13%)

CLEVELAND ACUTE STROKE EXPERIENCE
• Stroke QI requires data– quality of data varies (many hospitals = no data)– multiple barriers must be overcome (behavioral, political, resources)– team building through trust building
• Performance varies widely across hospitals– physicians and hospitals may not like their data– outliers may not mean bad care– community effectiveness may differ from NINDS efficacy
• Protocol deviations are very common – linked with bad outcomes
• Data can change behavior and improve stroke care – community performance improves over time with systematic QI
• Community hospitals can & should give IV tPA IF they are able to demonstrate they know how
