18. 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
